1.  Risk of Injurious Fall and Hip Fracture up to 26 y before the Diagnosis of Parkinson Disease: Nested Case–Control Studies in a Nationwide Cohort 
PLoS Medicine  2016;13(2):e1001954.
Background
Low muscle strength has been found in late adolescence in individuals diagnosed with Parkinson disease (PD) 30 y later. This study investigated whether this lower muscle strength also may translate into increased risks of falling and fracture before the diagnosis of PD.
Methods and Findings
Among all Swedish citizens aged ≥50 y in 2005, two nested case–control cohorts were compiled. In cohort I, individuals diagnosed with PD during 1988–2012 (n = 24,412) were matched with up to ten controls (n = 243,363), and the risk of fall-related injuries before diagnosis of PD was evaluated. In cohort II, individuals with an injurious fall in need of emergency care during 1988–2012 (n = 622,333) were matched with one control (n = 622,333), and the risk of PD after the injurious fall was evaluated. In cohort I, 18.0% of cases and 11.5% of controls had at least one injurious fall (p < 0.001) prior to PD diagnosis in the case. Assessed by conditional logistic regression analysis adjusted for comorbid diagnoses and education level, PD was associated with increased risks of injurious fall up to 10 y before diagnosis (odds ratio [OR] 1.19, 95% CI 1.08–1.31; 7 to <10 y before diagnosis) and hip fracture ≥15 y before diagnosis (OR 1.36, 95% CI 1.10–1.69; 15–26 y before diagnosis). In cohort II, 0.7% of individuals with an injurious fall and 0.5% of controls were diagnosed with PD during follow-up (p < 0.001). The risk of PD was increased for up to 10 y after an injurious fall (OR 1.18, 95% CI 1.02–1.37; 7 to <10 y after diagnosis). An important limitation is that the diagnoses were obtained from registers and could not be clinically confirmed for the study.
Conclusions
The increased risks of falling and hip fracture prior to the diagnosis of PD may suggest the presence of clinically relevant neurodegenerative impairment many years before the diagnosis of this disease.
In two nested case-control studies using data from a nationwide cohort, Peter Nordström and colleagues assess the risk of injurious fall and hip fracture up to 26 years before the diagnosis of Parkinson's disease.
Editors' Summary
Background
Parkinson disease (PD) is a common, progressive neurological disease. The disease is caused by the gradual loss of the nerve cells that usually produce dopamine, a neurotransmitter that regulates the body’s movements (motor functions). The symptoms of PD, which develop slowly, include tremor (involuntary trembling of the hands, legs, arm, jaw, and face), slow movement, impaired balance and coordination, and rigidity (muscle stiffness). As these symptoms worsen, affected individuals may have trouble walking, speaking, and swallowing, and they may fall frequently, fracturing bones. No drugs are available to halt the loss of dopamine-producing nerve cells, but medications that replace or mimic the lost dopamine can reduce the severity of these motor symptoms. PD does not directly kill people, and many people with PD have a normal or near-normal life expectancy. However, PD puts a great strain on the body, which makes affected individuals vulnerable to life-threatening infection such as pneumonia.
Why Was This Study Done?
The motor symptoms of PD do not usually develop until people are around 60 years old. However, nonspecific “prodromal” signs (for example, changes in smell perception) can occur many years earlier. Indeed, a recent study reported low muscle strength in late adolescence in patients diagnosed with PD decades later. Could reduced muscular strength be a marker of neuromuscular dysfunction (problems with the nerves that control movement), and could this dysfunction translate into an increased risk of falls and fractures years before PD diagnosis? Here, researchers investigate these questions by undertaking a nested case—control study in a nationwide cohort. A nested case—control study identifies all the individuals in a group (here, everyone living in Sweden who was 50 years old or older at the end of 2005) who have a specific condition (here, PD), identifies several matched individuals (people who are similar to the cases in terms of age, gender, and certain other characteristics) in the same cohort who do not have the condition, and asks whether the cases and controls differ in terms of a specific characteristic (here, falls and fall-related injuries up to 26 years before the diagnosis of PD).
What Did the Researchers Do and Find?
The researchers identified 24,412 Swedish citizens who were diagnosed with PD between 1988 and 2012 by examining the Swedish National Patient Register and matched each case with up to ten controls to form a nested case—control cohort. During an average study period of 20 years prior to a PD diagnosis, 18.0% of cases and 11.5% of controls had at least one fall that caused an injury requiring emergency care. After adjusting for other factors that might affect an individual’s risk of a fall, PD was associated with an increased risk of injurious falls up to ten years before diagnosis (an odds ratio [OR] of 1.19; an OR represents the chance that an outcome will occur given a particular exposure compared to the chance of the outcome occurring in the absence of that exposure) and with an increased risk of hip fracture more than 15 years before diagnosis (OR 1.36; hip fractures are particularly common among people with PD). The strength of these associations was increased closer to PD diagnosis. Finally, in a second nested case—control cohort in which individuals with a record of injurious falls were matched with individuals with no history of falls, the risk of PD was higher among individuals with an injurious fall than among those without during the first ten years after the first recorded fall.
What Do These Findings Mean?
The use of diagnoses obtained from registers that could not be clinically confirmed may limit the accuracy of these findings. Moreover, these findings cannot prove that there is a shared causal link between injurious falls and PD (although the time-dependent changes in the strength of the associations and the results from the second nested case—control cohort strongly suggest a direct link between injurious falls and subsequent PD). However, the finding that the risk of injurious falls—particularly the risk of falls resulting in hip fracture—is increased decades prior to the diagnosis of PD suggests that clinically relevant but subtle neurodegenerative impairment could be present many years before the clinical onset of PD. These findings, which identify potential markers of PD more than a decade before diagnosis, need to be confirmed in other settings but provide new insights into the earliest, hitherto unrecognized, stages of PD.

2.  Hip Fracture Incidence in Relation to Age, Menopausal Status, and Age at Menopause: Prospective Analysis 
PLoS Medicine  2009;6(11):e1000181.
Using data from the UK Million Women Study, Emily Banks and colleagues investigate the relationships between the incidence of hip fracture and a woman's age, menopausal status, and age at menopause.
Background
Bone mineral density is known to decrease rapidly after the menopause. There is limited evidence about the separate contributions of a woman's age, menopausal status and age at menopause to the incidence of hip fracture.
Methods and Findings
Over one million middle-aged women joined the UK Million Women Study in 1996–2001 providing information on their menopausal status, age at menopause, and other factors, which was updated, where possible, 3 y later. All women were registered with the UK National Health Service (NHS) and were routinely linked to information on cause-specific admissions to NHS hospitals. 561,609 women who had never used hormone replacement therapy and who provided complete information on menopausal variables (at baseline 25% were pre/perimenopausal and 75% postmenopausal) were followed up for a total of 3.4 million woman-years (an average 6.2 y per woman). During follow-up 1,676 (0.3%) were admitted to hospital with a first incident hip fracture. Among women aged 50–54 y the relative risk (RR) of hip fracture risk was significantly higher in postmenopausal than premenopausal women (adjusted RR 2.22, 95% confidence interval [CI] 1.22–4.04; p = 0.009); there were too few premenopausal women aged 55 y and over for valid comparisons. Among postmenopausal women, hip fracture incidence increased steeply with age (p<0.001), with rates being about seven times higher at age 70–74 y than at 50–54 y (incidence rates of 0.82 versus 0.11 per 100 women over 5 y). Among postmenopausal women of a given age there was no significant difference in hip fracture incidence between women whose menopause was due to bilateral oophorectomy compared to a natural menopause (adjusted RR 1.20, 95% CI 0.94–1.55; p = 0.15), and age at menopause had little, if any, effect on hip fracture incidence.
Conclusions
At around the time of the menopause, hip fracture incidence is about twice as high in postmenopausal than in premenopausal women, but this effect is short lived. Among postmenopausal women, age is by far the main determinant of hip fracture incidence and, for women of a given age, their age at menopause has, at most, a weak additional effect.

Editors' Summary
Background
Anyone can break a hip but most hip fractures occur in elderly people. As people age, their bones gradually lose minerals and become less dense, which weakens the bones and makes them more susceptible to fracture. Because women lose bone density faster than men as they age and because women constitute the majority of the elderly, three-quarters of hip fractures occur in women. Hip fractures can cause long-term health problems and premature death. Thus, although surgical repair of a broken hip usually only requires a hospital stay of about a week, a quarter of elderly people who were living independently before their fracture have to stay in a nursing home for at least a year after their injury and a fifth of elderly people who break a hip die within the year. Most hip fractures are caused by falls. Regular exercise to improve strength and balance combined with review of medicines (to reduce side effects and interactions), regular eye examinations, and the removal of fall hazards from the home can help to prevent hip fractures in elderly people.
Why Was This Study Done?
Bone density decreases very rapidly in women immediately after menopause—the time when menstruation permanently stops—and then continues to decrease more slowly with age. Most women have their menopause in their early 50s but menopause can occur in younger women. Early menopause is thought to be a risk factor for osteoporosis (thinning of the bones) and fractures later in life but little is known about how menopause influences hip fracture risk as women age. In this prospective study (a type of study in which a group of people is followed for several years to see whether they develop a particular condition), the researchers investigate the incidence of hip fractures in relation to age, menopausal status, and age at menopause among the participants of the Million Women Study. This study, which recruited 1.3 million women aged 50–64 years who attended UK breast cancer screening clinics between 1996 and 2001, has been investigating how reproductive and lifestyle factors affect women's health.
What Did the Researchers Do and Find?
At enrollment and three years later, the study participants provided information about their menopausal status and other health and lifestyle factors likely to affect their fracture risk. From these data, the researchers identified more than half a million women who had never used hormone replacement therapy (which reduces fracture risk) and who had given complete information about their menopausal status. They then looked for statistical associations between the occurrence of a first hip fracture in these women over the next few years and their age, menopausal status, and age at menopause. Among women aged 50–54 years, postmenopausal women were twice as likely to have a hip fracture as premenopausal women. Among postmenopausal women, the incidence of hip fractures increased steeply with age and was seven times higher in 70–74-year olds than in 50–54-year olds. Women who had their menopause before age 45 had a slightly increased risk of hip fracture but any effect of age at menopause on the risk of hip fracture was small compared to the effect of age itself, and the slightly increased risk may have been due to other factors that could not be fully accounted for in the analysis.
What Do These Findings Mean?
These findings indicate that around the time of menopause, although hip fractures are rare, the risk of a fracture in postmenopausal women is twice that in premenopausal women. The findings also show that among postmenopausal women, age is the major determinant of hip fracture risk and that for women of a given age, their age at menopause has little effect on hip fracture risk. Women attending breast cancer screening clinics and completing questionnaires about their health may not be representative of the general population. Furthermore, these findings rely on women self-reporting their menopausal status accurately. Nevertheless, the results of this study suggest that clinicians advising women about hip fracture prevention should probably base their advice on the woman's age and on age-related factors such as frailty rather than on factors related to menopause. Clinicians can also now reassure elderly women who had an early menopause that their risk of hip fracture is unlikely to be higher than that of similar women who had a later menopause.

3.  Prevention of Falls and Fall-Related Injuries in Community-Dwelling Seniors 
Executive Summary
In early August 2007, the Medical Advisory Secretariat began work on the Aging in the Community project, an evidence-based review of the literature surrounding healthy aging in the community. The Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the ministry’s newly released Aging at Home Strategy.
After a broad literature review and consultation with experts, the secretariat identified 4 key areas that strongly predict an elderly person’s transition from independent community living to a long-term care home. Evidence-based analyses have been prepared for each of these 4 areas: falls and fall-related injuries, urinary incontinence, dementia, and social isolation. For the first area, falls and fall-related injuries, an economic model is described in a separate report.
Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/mas_about.html, to review these titles within the Aging in the Community series.

Caregiver- and Patient-Directed Interventions for Dementia: An Evidence-Based Analysis

The Falls/Fractures Economic Model in Ontario Residents Aged 65 Years and Over (FEMOR)
Objective
To identify interventions that may be effective in reducing the probability of an elderly person’s falling and/or sustaining a fall-related injury.
Background
Although estimates of fall rates vary widely based on the location, age, and living arrangements of the elderly population, it is estimated that each year approximately 30% of community-dwelling individuals aged 65 and older, and 50% of those aged 85 and older will fall. Of those individuals who fall, 12% to 42% will have a fall-related injury.
Several meta-analyses and cohort studies have identified falls and fall-related injuries as a strong predictor of admission to a long-term care (LTC) home. It has been shown that the risk of LTC home admission is over 5 times higher in seniors who experienced 2 or more falls without injury, and over 10 times higher in seniors who experienced a fall causing serious injury.
Falls result from the interaction of a variety of risk factors that can be both intrinsic and extrinsic. Intrinsic factors are those that pertain to the physical, demographic, and health status of the individual, while extrinsic factors relate to the physical and socio-economic environment. Intrinsic risk factors can be further grouped into psychosocial/demographic risks, medical risks, risks associated with activity level and dependence, and medication risks. Commonly described extrinsic risks are tripping hazards, balance and slip hazards, and vision hazards.
Note: It is recognized that the terms “senior” and “elderly” carry a range of meanings for different audiences; this report generally uses the former, but the terms are treated here as essentially interchangeable.
Evidence-Based Analysis of Effectiveness
Research Question
Since many risk factors for falls are modifiable, what interventions (devices, systems, programs) exist that reduce the risk of falls and/or fall-related injuries for community-dwelling seniors?
Inclusion and Exclusion Criteria
Inclusion Criteria
English language;
published between January 2000 and September 2007;
population of community-dwelling seniors (majority aged 65+); and
randomized controlled trials (RCTs), quasi-experimental trials, systematic reviews, or meta-analyses.
Exclusion Criteria
special populations (e.g., stroke or osteoporosis; however, studies restricted only to women were included);
studies only reporting surrogate outcomes; or
studies whose outcome cannot be extracted for meta-analysis.
Outcomes of Interest
number of fallers, and
number of falls resulting in injury/fracture.
Search Strategy
A search was performed in OVID MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, EMBASE, the Cumulative Index to Nursing & Allied Health Literature (CINAHL), The Cochrane Library, and the International Agency for Health Technology Assessment (INAHTA) for studies published between January 2000 and September 2007. Furthermore, all studies included in a 2003 Cochrane review were considered for inclusion in this analysis. Abstracts were reviewed by a single author, and studies meeting the inclusion criteria outlined above were obtained. Studies were grouped based on intervention type, and data on population characteristics, fall outcomes, and study design were extracted. Reference lists were also checked for relevant studies. The quality of the evidence was assessed as high, moderate, low, or very low according to the GRADE methodology.
Summary of Findings
The following 11 interventions were identified in the literature search: exercise programs, vision assessment and referral, cataract surgery, environmental modifications, vitamin D supplementation, vitamin D plus calcium supplementation, hormone replacement therapy (HRT), medication withdrawal, gait-stabilizing devices, hip protectors, and multifactorial interventions.
Exercise programs were stratified into targeted programs where the exercise routine was tailored to the individuals’ needs, and untargeted programs that were identical among subjects. Furthermore, analyses were stratified by exercise program duration (<6 months and ≥6 months) and fall risk of study participants. Similarly, the analyses on the environmental modification studies were stratified by risk. Low-risk study participants had had no fall in the year prior to study entry, while high-risk participants had had at least one fall in the previous year.
A total of 17 studies investigating multifactorial interventions were identified in the literature search. Of these studies, 10 reported results for a high-risk population with previous falls, while 6 reported results for study participants representative of the general population. One study provided stratified results by fall risk, and therefore results from this study were included in each stratified analysis.

CI refers to confidence interval; RR, relative risk.
Odds ratio is reported, because RR was not available.
Conclusions
High-quality evidence indicates that long-term exercise programs in mobile seniors and environmental modifications in the homes of frail elderly persons will effectively reduce falls and possibly fall-related injuries in Ontario’s elderly population.
A combination of vitamin D and calcium supplementation in elderly women will help reduce the risk of falls by more than 40%.
The use of outdoor gait-stabilizing devices for mobile seniors during the winter in Ontario may reduce falls and fall-related injuries; however, evidence is limited and more research is required in this area.
While psychotropic medication withdrawal may be an effective method for reducing falls, evidence is limited and long-term compliance has been demonstrated to be difficult to achieve.
Multifactorial interventions in high-risk populations may be effective; however, the effect is only marginally significant, and the quality of evidence is low.

4.  Utilization of DXA Bone Mineral Densitometry in Ontario 
Executive Summary
Issue
Systematic reviews and analyses of administrative data were performed to determine the appropriate use of bone mineral density (BMD) assessments using dual energy x-ray absorptiometry (DXA), and the associated trends in wrist and hip fractures in Ontario.
Background
Dual Energy X-ray Absorptiometry Bone Mineral Density Assessment
Dual energy x-ray absorptiometry bone densitometers measure bone density based on differential absorption of 2 x-ray beams by bone and soft tissues. It is the gold standard for detecting and diagnosing osteoporosis, a systemic disease characterized by low bone density and altered bone structure, resulting in low bone strength and increased risk of fractures. The test is fast (approximately 10 minutes) and accurate (exceeds 90% at the hip), with low radiation (1/3 to 1/5 of that from a chest x-ray). DXA densitometers are licensed as Class 3 medical devices in Canada. The World Health Organization has established criteria for osteoporosis and osteopenia based on DXA BMD measurements: osteoporosis is defined as a BMD that is >2.5 standard deviations below the mean BMD for normal young adults (i.e. T-score <–2.5), while osteopenia is defined as BMD that is more than 1 standard deviation but less than 2.5 standard deviation below the mean for normal young adults (i.e. T-score< –1 & ≥–2.5). DXA densitometry is presently an insured health service in Ontario.
Clinical Need
 
Burden of Disease
The Canadian Multicenter Osteoporosis Study (CaMos) found that 16% of Canadian women and 6.6% of Canadian men have osteoporosis based on the WHO criteria, with prevalence increasing with age. Osteopenia was found in 49.6% of Canadian women and 39% of Canadian men. In Ontario, it is estimated that nearly 530,000 Ontarians have some degrees of osteoporosis. Osteoporosis-related fragility fractures occur most often in the wrist, femur and pelvis. These fractures, particularly those in the hip, are associated with increased mortality, and decreased functional capacity and quality of life. A Canadian study showed that at 1 year after a hip fracture, the mortality rate was 20%. Another 20% required institutional care, 40% were unable to walk independently, and there was lower health-related quality of life due to attributes such as pain, decreased mobility and decreased ability to self-care. The cost of osteoporosis and osteoporotic fractures in Canada was estimated to be $1.3 billion in 1993.
Guidelines for Bone Mineral Density Testing
With 2 exceptions, almost all guidelines address only women. None of the guidelines recommend blanket population-based BMD testing. Instead, all guidelines recommend BMD testing in people at risk of osteoporosis, predominantly women aged 65 years or older. For women under 65 years of age, BMD testing is recommended only if one major or two minor risk factors for osteoporosis exist. Osteoporosis Canada did not restrict its recommendations to women, and thus their guidelines apply to both sexes. Major risk factors are age greater than or equal to 65 years, a history of previous fractures, family history (especially parental history) of fracture, and medication or disease conditions that affect bone metabolism (such as long-term glucocorticoid therapy). Minor risk factors include low body mass index, low calcium intake, alcohol consumption, and smoking.
Current Funding for Bone Mineral Density Testing
The Ontario Health Insurance Program (OHIP) Schedule presently reimburses DXA BMD at the hip and spine. Measurements at both sites are required if feasible. Patients at low risk of accelerated bone loss are limited to one BMD test within any 24-month period, but there are no restrictions on people at high risk. The total fee including the professional and technical components for a test involving 2 or more sites is $106.00 (Cdn).
Method of Review
This review consisted of 2 parts. The first part was an analysis of Ontario administrative data relating to DXA BMD, wrist and hip fractures, and use of antiresorptive drugs in people aged 65 years and older. The Institute for Clinical Evaluative Sciences extracted data from the OHIP claims database, the Canadian Institute for Health Information hospital discharge abstract database, the National Ambulatory Care Reporting System, and the Ontario Drug Benefit database using OHIP and ICD-10 codes. The data was analyzed to examine the trends in DXA BMD use from 1992 to 2005, and to identify areas requiring improvement.
The second part included systematic reviews and analyses of evidence relating to issues identified in the analyses of utilization data. Altogether, 8 reviews and qualitative syntheses were performed, consisting of 28 published systematic reviews and/or meta-analyses, 34 randomized controlled trials, and 63 observational studies.
Findings of Utilization Analysis
Analysis of administrative data showed a 10-fold increase in the number of BMD tests in Ontario between 1993 and 2005.
OHIP claims for BMD tests are presently increasing at a rate of 6 to 7% per year. Approximately 500,000 tests were performed in 2005/06 with an age-adjusted rate of 8,600 tests per 100,000 population.
Women accounted for 90 % of all BMD tests performed in the province.
In 2005/06, there was a 2-fold variation in the rate of DXA BMD tests across local integrated health networks, but a 10-fold variation between the county with the highest rate (Toronto) and that with the lowest rate (Kenora). The analysis also showed that:
With the increased use of BMD, there was a concomitant increase in the use of antiresorptive drugs (as shown in people 65 years and older) and a decrease in the rate of hip fractures in people age 50 years and older.
Repeat BMD made up approximately 41% of all tests. Most of the people (>90%) who had annual BMD tests in a 2-year or 3-year period were coded as being at high risk for osteoporosis.
18% (20,865) of the people who had a repeat BMD within a 24-month period and 34% (98,058) of the people who had one BMD test in a 3-year period were under 65 years, had no fracture in the year, and coded as low-risk.
Only 19% of people age greater than 65 years underwent BMD testing and 41% received osteoporosis treatment during the year following a fracture.
Men accounted for 24% of all hip fractures and 21 % of all wrist fractures, but only 10% of BMD tests. The rates of BMD tests and treatment in men after a fracture were only half of those in women.
In both men and women, the rate of hip and wrist fractures mainly increased after age 65 with the sharpest increase occurring after age 80 years.
Findings of Systematic Review and Analysis
Serial Bone Mineral Density Testing for People Not Receiving Osteoporosis Treatment
A systematic review showed that the mean rate of bone loss in people not receiving osteoporosis treatment (including postmenopausal women) is generally less than 1% per year. Higher rates of bone loss were reported for people with disease conditions or on medications that affect bone metabolism. In order to be considered a genuine biological change, the change in BMD between serial measurements must exceed the least significant change (variability) of the testing, ranging from 2.77% to 8% for precisions ranging from 1% to 3% respectively. Progression in BMD was analyzed, using different rates of baseline BMD values, rates of bone loss, precision, and BMD value for initiating treatment. The analyses showed that serial BMD measurements every 24 months (as per OHIP policy for low-risk individuals) is not necessary for people with no major risk factors for osteoporosis, provided that the baseline BMD is normal (T-score ≥ –1), and the rate of bone loss is less than or equal to 1% per year. The analyses showed that for someone with a normal baseline BMD and a rate of bone loss of less than 1% per year, the change in BMD is not likely to exceed least significant change (even for a 1% precision) in less than 3 years after the baseline test, and is not likely to drop to a BMD level that requires initiation of treatment in less than 16 years after the baseline test.
Serial Bone Mineral Density Testing in People Receiving Osteoporosis Therapy
Seven published meta-analysis of randomized controlled trials (RCTs) and 2 recent RCTs on BMD monitoring during osteoporosis therapy showed that although higher increases in BMD were generally associated with reduced risk of fracture, the change in BMD only explained a small percentage of the fracture risk reduction.
Studies showed that some people with small or no increase in BMD during treatment experienced significant fracture risk reduction, indicating that other factors such as improved bone microarchitecture might have contributed to fracture risk reduction.
There is conflicting evidence relating to the role of BMD testing in improving patient compliance with osteoporosis therapy.
Even though BMD may not be a perfect surrogate for reduction in fracture risk when monitoring responses to osteoporosis therapy, experts advised that it is still the only reliable test available for this purpose.
A systematic review conducted by the Medical Advisory Secretariat showed that the magnitude of increases in BMD during osteoporosis drug therapy varied among medications. Although most of the studies yielded mean percentage increases in BMD from baseline that did not exceed the least significant change for a 2% precision after 1 year of treatment, there were some exceptions.
Bone Mineral Density Testing and Treatment After a Fragility Fracture
A review of 3 published pooled analyses of observational studies and 12 prospective population-based observational studies showed that the presence of any prevalent fracture increases the relative risk for future fractures by approximately 2-fold or more. A review of 10 systematic reviews of RCTs and 3 additional RCTs showed that therapy with antiresorptive drugs significantly reduced the risk of vertebral fractures by 40 to 50% in postmenopausal osteoporotic women and osteoporotic men, and 2 antiresorptive drugs also reduced the risk of nonvertebral fractures by 30 to 50%. Evidence from observational studies in Canada and other jurisdictions suggests that patients who had undergone BMD measurements, particularly if a diagnosis of osteoporosis is made, were more likely to be given pharmacologic bone-sparing therapy. Despite these findings, the rate of BMD investigation and osteoporosis treatment after a fracture remained low (<20%) in Ontario as well as in other jurisdictions.
Bone Mineral Density Testing in Men
There are presently no specific Canadian guidelines for BMD screening in men. A review of the literature suggests that risk factors for fracture and the rate of vertebral deformity are similar for men and women, but the mortality rate after a hip fracture is higher in men compared with women. Two bisphosphonates had been shown to reduce the risk of vertebral and hip fractures in men. However, BMD testing and osteoporosis treatment were proportionately low in Ontario men in general, and particularly after a fracture, even though men accounted for 25% of the hip and wrist fractures. The Ontario data also showed that the rates of wrist fracture and hip fracture in men rose sharply in the 75- to 80-year age group.
Ontario-Based Economic Analysis
The economic analysis focused on analyzing the economic impact of decreasing future hip fractures by increasing the rate of BMD testing in men and women age greater than or equal to 65 years following a hip or wrist fracture. A decision analysis showed the above strategy, especially when enhanced by improved reporting of BMD tests, to be cost-effective, resulting in a cost-effectiveness ratio ranging from $2,285 (Cdn) per fracture avoided (worst-case scenario) to $1,981 (Cdn) per fracture avoided (best-case scenario). A budget impact analysis estimated that shifting utilization of BMD testing from the low risk population to high risk populations within Ontario would result in a saving of $0.85 million to $1.5 million (Cdn) to the health system. The potential net saving was estimated at $1.2 million to $5 million (Cdn) when the downstream cost-avoidance due to prevention of future hip fractures was factored into the analysis.
Other Factors for Consideration
There is a lack of standardization for BMD testing in Ontario. Two different standards are presently being used and experts suggest that variability in results from different facilities may lead to unnecessary testing. There is also no requirement for standardized equipment, procedure or reporting format. The current reimbursement policy for BMD testing encourages serial testing in people at low risk of accelerated bone loss. This review showed that biannual testing is not necessary for all cases. The lack of a database to collect clinical data on BMD testing makes it difficult to evaluate the clinical profiles of patients tested and outcomes of the BMD tests. There are ministry initiatives in progress under the Osteoporosis Program to address the development of a mandatory standardized requisition form for BMD tests to facilitate data collection and clinical decision-making. Work is also underway for developing guidelines for BMD testing in men and in perimenopausal women.
Conclusion
Increased use of BMD in Ontario since 1996 appears to be associated with increased use of antiresorptive medication and a decrease in hip and wrist fractures.
Data suggest that as many as 20% (98,000) of the DXA BMD tests in Ontario in 2005/06 were performed in people aged less than 65 years, with no fracture in the current year, and coded as being at low risk for accelerated bone loss; this is not consistent with current guidelines. Even though some of these people might have been incorrectly coded as low-risk, the number of tests in people truly at low risk could still be substantial.
Approximately 4% (21,000) of the DXA BMD tests in 2005/06 were repeat BMDs in low-risk individuals within a 24-month period. Even though this is in compliance with current OHIP reimbursement policies, evidence showed that biannual serial BMD testing is not necessary in individuals without major risk factors for fractures, provided that the baseline BMD is normal (T-score < –1). In this population, BMD measurements may be repeated in 3 to 5 years after the baseline test to establish the rate of bone loss, and further serial BMD tests may not be necessary for another 7 to 10 years if the rate of bone loss is no more than 1% per year. Precision of the test needs to be considered when interpreting serial BMD results.
Although changes in BMD may not be the perfect surrogate for reduction in fracture risk as a measure of response to osteoporosis treatment, experts advised that it is presently the only reliable test for monitoring response to treatment and to help motivate patients to continue treatment. Patients should not discontinue treatment if there is no increase in BMD after the first year of treatment. Lack of response or bone loss during treatment should prompt the physician to examine whether the patient is taking the medication appropriately.
Men and women who have had a fragility fracture at the hip, spine, wrist or shoulder are at increased risk of having a future fracture, but this population is presently under investigated and under treated. Additional efforts have to be made to communicate to physicians (particularly orthopaedic surgeons and family physicians) and the public about the need for a BMD test after fracture, and for initiating treatment if low BMD is found.
Men had a disproportionately low rate of BMD tests and osteoporosis treatment, especially after a fracture. Evidence and fracture data showed that the risk of hip and wrist fractures in men rises sharply at age 70 years.
Some counties had BMD utilization rates that were only 10% of that of the county with the highest utilization. The reasons for low utilization need to be explored and addressed.
Initiatives such as aligning reimbursement policy with current guidelines, developing specific guidelines for BMD testing in men and perimenopausal women, improving BMD reports to assist in clinical decision making, developing a registry to track BMD tests, improving access to BMD tests in remote/rural counties, establishing mechanisms to alert family physicians of fractures, and educating physicians and the public, will improve the appropriate utilization of BMD tests, and further decrease the rate of fractures in Ontario. Some of these initiatives such as developing guidelines for perimenopausal women and men, and developing a standardized requisition form for BMD testing, are currently in progress under the Ontario Osteoporosis Strategy.

5.  Balloon Kyphoplasty 
Executive Summary
Objective
To review the evidence on the effectiveness and cost-effectiveness of balloon kyphoplasty for the treatment of vertebral compression fractures (VCFs).
Clinical Need
Vertebral compression fractures are one of the most common types of osteoporotic fractures. They can lead to chronic pain and spinal deformity. They are caused when the vertebral body (the thick block of bone at the front of each vertebra) is too weak to support the loads of activities of daily living. Spinal deformity due to a collapsed vertebral body can substantially affect the quality of life of elderly people, who are especially at risk for osteoporotic fractures due to decreasing bone mass with age. A population-based study across 12 European centres recently found that VCFs have a negative impact on health-related quality of life. Complications associated with VCFs are pulmonary dysfunction, eating disorders, loss of independence, and mental status change due to pain and the use of medications. Osteoporotic VCFs also are associated with a higher rate of death.
VCFs affect an estimated 25% of women over age 50 years and 40% of women over age 80 years. Only about 30% of these fractures are diagnosed in clinical practice. A Canadian multicentre osteoporosis study reported on the prevalence of vertebral deformity in Canada in people over 50 years of age. To define the limit of normality, they plotted a normal distribution, including mean and standard deviations (SDs) derived from a reference population without any deformity. They reported a prevalence rate of 23.5% in women and a rate of 21.5% in men, using 3 SDs from the mean as the limit of normality. When they used 4 SDs, the prevalence was 9.3% and 7.3%, respectively. They also found the prevalence of vertebral deformity increased with age. For people older than 80 years of age, the prevalence for women and men was 45% and 36%, respectively, using 3 SDs as the limit of normality.
About 85% of VCFs are due to primary osteoporosis. Secondary osteoporosis and neoplasms account for the remaining 15%. A VCF is operationally defined as a reduction in vertebral body height of at least 20% from the initial measurement. It is considered mild if the reduction in height is between 20% and 25%; moderate, if it is between 25% and 40%; and severs, if it is more than 40%. The most frequently fractured locations are the third-lower part of the thorax and the superior lumbar levels. The cervical vertebrae and the upper third of the thorax are rarely involved.
Traditionally, bed rest, medication, and bracing are used to treat painful VCFs. However, anti-inflammatory and narcotic medications are often poorly tolerated by the elderly and may harm the gastrointestinal tract. Bed rest and inactivity may accelerate bone loss, and bracing may restrict diaphragmatic movement. Furthermore, medical treatment does not treat the fracture in a way that ameliorates the pain and spinal deformity.
Over the past decade, the injection of bone cement through the skin into a fractured vertebral body has been used to treat VCFs. The goal of cement injection is to reduce pain by stabilizing the fracture. The secondary indication of these procedures is management of painful vertebral fractures caused by benign or malignant neoplasms (e.g., hemangioma, multiple myeloma, and metastatic cancer).
The Technology
Balloon kyphoplasty is a modified vertebroplasty technique. It is a minimally invasive procedure that aims to relieve pain, restore vertebral height, and correct kyphosis. During this procedure, an inflatable bone tamp is inserted into the collapsed vertebral body. Once inflated, the balloon elevates the end plates and thereby restores the height of the vertebral body. The balloon is deflated and removed, and the space is filled with bone cement. Creating a space in the vertebral body enables the application of more viscous cement and at a much lower pressure than is needed for vertebroplasty. This may result in less cement leakage and fewer complications. Balloons typically are inserted bilaterally, into each fractured vertebral body. Kyphoplasty usually is done under general anesthesia in about 1.5 hours. Patients typically are observed for only a few hours after the surgery, but some may require an overnight hospital stay.
Health Canada has licensed KyphX Xpander Inflatable Bone Tamp (Kyphon Inc., Sunnyvale, CA), for kyphoplasty in patients with VCFs. KyphX is the only commercially available device for percutaneous kyphoplasty. The KyphX kit uses a series of bone filler device tubes. Each bone filler device must be loaded manually with cement. The cement is injected into the cavity by pressing an inner stylet.
In the United States, the Food and Drug Administration cleared the KyphX Inflatable Bone Tamp for marketing in July 1998. CE (Conformité European) marketing was obtained in February 2000 for the reduction of fracture and/or creation of a void in cancellous bone.
Review Strategy
The aim of this literature review was to evaluate the safety and effectiveness of balloon kyphoplasty in the treatment of painful VCFs.
INAHTA, Cochrane CCTR (formerly Cochrane Controlled Trials Register), and DSR were searched for health technology assessment reports. In addition, MEDLINE, EMBASE, and MEDLINE In-Process & Other Non-Indexed Citations were searched from January 1, 2000 to September 21, 2004. The search was limited to English-language articles and human studies.
The positive end points selected for this assessment were as follows:
Reduction in pain scores
Reduction in vertebral height loss
Reduction in kyphotic (Cobb) angle
Improvement in quality of life scores
The search did not yield any health technology assessments on balloon kyphoplasty. The search yielded 152 citations, including those for review articles. No randomized controlled trials (RCTs) on balloon kyphoplasty were identified. All of the published studies were either prospective cohort studies or retrospective studies with no controls. Eleven studies (all case series) met the inclusion criteria. There was also a comparative study published in German that had been translated into English.
Summary of Findings
The results of the 1 comparative study (level 3a evidence) that was included in this review showed that, compared with conservative medical care, balloon kyphoplasty significantly improved patient outcomes.
Patients who had balloon kyphoplasty reported a significant reduction in pain that was maintained throughout follow-up (6 months), whereas pain scores did not change in the control group. Patients in the balloon kyphoplasty group did not need pain medication after 3 days. In the control group, about one-half of the patients needed more pain medication in the first 4 weeks after the procedure. After 6 weeks, 82% of the patients in the control group were still taking pain medication regularly.
Adjacent fractures were more frequent in the control group than in the balloon kyphoplasty group.
The case series reported on several important clinical outcomes.
Pain: Four studies on osteoporosis patients and 1 study on patients with multiple myeloma/primary cancers used the Visual Analogue Scale (VAS) to measure pain before and after balloon kyphoplasty. All of these studies reported that patients had significantly less pain after the procedure. This was maintained during follow-up. Two other studies on patients with osteoporosis also used the VAS to measure pain and found a significant improvement in pain scores; however, they did not provide follow-up data.
Vertebral body height: All 5 studies that assessed vertebral body height in patients with osteoporosis reported a significant improvement in vertebral body height after balloon kyphoplasty. One study had 1-year follow-up data for 26 patients. Vertebral body height was significantly better at 6 months and 1 year for both the anterior and midline measurements.
Two studies reported that vertebral body height was restored significantly after balloon kyphoplasty for patients with multiple myeloma or metastatic disease. In another study, the researchers reported complete height restoration in 9% of patients, a mean 56% height restoration in 60% of patients, and no appreciable height restoration in 31% of the patients who received balloon kyphoplasty.
Kyphosis correction: Four studies that assessed Cobb angle before and after balloon kyphoplasty in patients with osteoporosis found a significant reduction in degree of kyphosis after the procedure. In these studies, the differences between preoperative and postoperative Cobb angles were 3.4°, 7°, 8.8°, and 9.9°.
Only 1 study investigated kyphosis correction in patients with multiple myeloma or metastatic disease. The authors reported a significant improvement (5.2°) in local kyphosis.
Quality of life: Four studies used the Short Form 36 (SF-36) Health Survey Questionnaire to measure the quality of life in patients with osteoporosis after they had balloon kyphoplasty. A significant improvement in most of the domains of the SF-36 (bodily pain, social functioning, vitality, physical functioning, mental health, and role functioning) was observed in 2 studies. One study found that general health declined, although not significantly, and another found that role emotional declined.
Both studies that used the Oswestry Disability Index found that patients had a better quality of life after balloon kyphoplasty. In one study, this improvement was statistically significant. In another study, researchers found that quality of life after kyphoplasty improved significantly, as measured with the Roland-Morris Disability Questionnaire. Yet another study used a quality of life questionnaire and found that 62% of the patients that had balloon kyphoplasty had returned to normal activities, whereas 2 patients had reduced mobility.
To measure quality of life in patients with multiple myeloma or metastatic disease, one group of researchers used the SF-36 and found significantly better scores on bodily pain, physical functioning, vitality, and social functioning after kyphoplasty. However, the scores for general health, mental health, role physical, and role emotional had not improved. A study that used the Oswestry Disability Index reported that patients’ scores were better postoperatively and at 3 months follow-up.
These were the main findings on complications in patients with osteoporosis:
The bone cement leaked in 37 (6%) of 620 treated fractures.
There were no reports of neurological deficits.
There were no reports of pulmonary embolism due to cement leakage.
There were 6 cases of cardiovascular events in 362 patients:
3 (0.8%) patients had myocardial infarction.
3 (0.8%) patients had cardiac arrhythmias.
There was 1 (0.27%) case of pulmonary embolism due to deep venous thrombosis.
There were 20 (8.4%) cases of new fractures in 238 patients.
For patients with multiple myeloma or metastatic disease, these were the main findings:
The bone cement leaked in 12 (9.6%) of 125 procedures.
There were no reports of neurological deficits.
Economic Analysis
Balloon kyphoplasty requires anesthesia. Standard vertebroplasty requires sedation and an analgesic. Based on these considerations, the professional fees (Cdn) for each procedure is shown in Table 1.
Professional Fees for Standard Vertebroplasty and Balloon Kyphoplasty
Balloon kyphoplasty has a sizable device cost add-on of $3,578 (the device cost per case) that standard vertebroplasty does not have. Therefore, the up-front cost (i.e., physician’s fees and device costs) is $187 for standard vertebroplasty and $3,812 for balloon kyphoplasty. (All costs are in Canadian currency.)
There are also “downstream costs” of the procedures, based on the different adverse outcomes associated with each. This includes the risk of developing new fractures (21% for vertebroplasty vs. 8.4% for balloon kyphoplasty), neurological complications (3.9% for vertebroplasty vs. 0% for balloon kyphoplasty), pulmonary embolism (0.1% for vertebroplasty vs. 0% for balloon kyphoplasty), and cement leakage (26.5% for vertebroplasty vs. 6.0% for balloon kyphoplasty). Accounting for these risks, and the base costs to treat each of these complications, the expected downstream costs are estimated at less than $500 per case. Therefore, the expected total direct medical cost per patient is about $700 for standard vertebroplasty and $4,300 for balloon kyphoplasty.
Kyphon, the manufacturer of the inflatable bone tamps has stated that the predicted Canadian incidence of osteoporosis in 2005 is about 29,000. The predicted incidence of cancer-related vertebral fractures in 2005 is 6,731. Based on Ontario having about 38% of the Canadian population, the incidence in the province is likely to be about 11,000 for osteoporosis and 2,500 for cancer-related vertebral fractures. This means there could be as many as 13,500 procedures per year in Ontario; however, this is highly unlikely because most of the cancer-related fractures likely would be treated with medication. Given a $3,600 incremental direct medical cost associated with balloon kyphoplasty, the budget impact of adopting this technology could be as high as $48.6 million per year; however, based on data from the Provider Services Branch, about 120 standard vertebroplasties are done in Ontario annually. Given these current utilization patterns, the budget impact is likely to be in the range of $430,000 per year. This is because of the sizable device cost add-on of $3,578 (per case) for balloon kyphoplasty that standard vertebroplasty does not have.
Policy Considerations
Other treatments for osteoporotic VCFs are medical management and open surgery. In cases without neurological involvement, the medical treatment of osteoporotic VCFs comprises bed rest, orthotic management, and pain medication. However, these treatments are not free of side effects. Bed rest over time can result in more bone and muscle loss, and can speed the deterioration of the underlying condition. Medication can lead to altered mood or mental status. Surgery in these patients has been limited because of its inherent risks and invasiveness, and the poor quality of osteoporotic bones. However, it may be indicated in patients with neurological deficits.
Neither of these vertebral augmentation procedures eliminates the need for aggressive treatment of osteoporosis. Osteoporotic VCFs are often under-diagnosed and under-treated. A survey of physicians in Ontario (1) who treated elderly patients living in long-term care homes found that although these physicians were aware of the rates of osteoporosis in these patients, 45% did not routinely assess them for osteoporosis, and 26% did not routinely treat them for osteoporosis.
Management of the underlying condition that weakens the vertebral bodies should be part of the treatment plan. All patients with osteoporosis should be in a medical therapy program to treat the underlying condition, and the referring health care provider should monitor the clinical progress of the patient.
The main complication associated with vertebroplasty and balloon kyphoplasty is cement leakage (extravertebral or vascular). This may result in more patient morbidity, longer hospitalizations, the need for open surgery, and the use of pain medications, all of which have related costs. Extravertebral cement leakage can cause neurological complications, like spinal cord compression, nerve root compression, and radiculopathy. In some cases, surgery is required to remove the cement and release the nerve. The rate of cement leakage is much lower after balloon kyphoplasty than after vertebroplasty. Furthermore, the neurological complications seen with vertebroplasty have not seen in the studies of balloon kyphoplasty. Rarely, cement leakage into the venous system will cause a pulmonary embolism. Finally, compared with vertebroplasty, the rate of new fractures is lower after balloon kyphoplasty.
Diffusion – International, National, Provincial
In Canada, balloon kyphoplasty has not yet been funded in any of the provinces. The first balloon kyphoplasty performed in Canada was in July 2004 in Ontario.
In the United States, the technology is considered by some states as medically reasonable and necessary for the treatment of painful vertebral body compression fractures.
Conclusion
There is level 4 evidence that balloon kyphoplasty to treat pain associated with VCFs due to osteoporosis is as effective as vertebroplasty at relieving pain. Furthermore, the evidence suggests that it restores the height of the affected vertebra. It also results in lower fracture rates in other vertebrae compared with vertebroplasty, and in fewer neurological complications due to cement leakage compared with vertebroplasty. Balloon kyphoplasty is a reasonable alternative to vertebroplasty, although it must be reiterated that this conclusion is based on evidence from level 4 studies.
Balloon kyphoplasty should be restricted to facilities that have sufficient volumes to develop and maintain the expertise required to maximize good quality outcomes. Therefore, consideration should be given to limiting the number of facilities in the province that can do balloon kyphoplasty.

6.  Caregiver- and Patient-Directed Interventions for Dementia 
Executive Summary
In early August 2007, the Medical Advisory Secretariat began work on the Aging in the Community project, an evidence-based review of the literature surrounding healthy aging in the community. The Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the ministry’s newly released Aging at Home Strategy.
After a broad literature review and consultation with experts, the secretariat identified 4 key areas that strongly predict an elderly person’s transition from independent community living to a long-term care home. Evidence-based analyses have been prepared for each of these 4 areas: falls and fall-related injuries, urinary incontinence, dementia, and social isolation. For the first area, falls and fall-related injuries, an economic model is described in a separate report.
Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/mas_about.html, to review these titles within the Aging in the Community series.

Introduction
Caregiver-Directed Interventions for Dementia
Patient-Directed Interventions for Dementia
Economic Analysis of Caregiver- and Patient-Directed Interventions for Dementia
Caregiver-Directed Interventions for Dementia
Objective
To identify interventions that may be effective in supporting the well-being of unpaid caregivers of seniors with dementia living in the community.
Clinical Need: Target Population and Condition
Dementia is a progressive and largely irreversible syndrome that is characterized by a loss of cognitive function severe enough to impact social or occupational functioning. The components of cognitive function affected include memory and learning, attention, concentration and orientation, problem-solving, calculation, language, and geographic orientation. Dementia was identified as one of the key predictors in a senior’s transition from independent community living to admission to a long-term care (LTC) home, in that approximately 90% of individuals diagnosed with dementia will be institutionalized before death. In addition, cognitive decline linked to dementia is one of the most commonly cited reasons for institutionalization.
Prevalence estimates of dementia in the Ontario population have largely been extrapolated from the Canadian Study of Health and Aging conducted in 1991. Based on these estimates, it is projected that there will be approximately 165,000 dementia cases in Ontario in the year 2008, and by 2010 the number of cases will increase by nearly 17% over 2005 levels. By 2020 the number of cases is expected to increase by nearly 55%, due to a rise in the number of people in the age categories with the highest prevalence (85+). With the increase in the aging population, dementia will continue to have a significant economic impact on the Canadian health care system. In 1991, the total costs associated with dementia in Canada were $3.9 billion (Cdn) with $2.18 billion coming from LTC.
Caregivers play a crucial role in the management of individuals with dementia because of the high level of dependency and morbidity associated with the condition. It has been documented that a greater demand is faced by dementia caregivers compared with caregivers of persons with other chronic diseases. The increased burden of caregiving contributes to a host of chronic health problems seen among many informal caregivers of persons with dementia. Much of this burden results from managing the behavioural and psychological symptoms of dementia (BPSD), which have been established as a predictor of institutionalization for elderly patients with dementia.
It is recognized that for some patients with dementia, an LTC facility can provide the most appropriate care; however, many patients move into LTC unnecessarily. For individuals with dementia to remain in the community longer, caregivers require many types of formal and informal support services to alleviate the stress of caregiving. These include both respite care and psychosocial interventions. Psychosocial interventions encompass a broad range of interventions such as psychoeducational interventions, counseling, supportive therapy, and behavioural interventions.
Assuming that 50% of persons with dementia live in the community, a conservative estimate of the number of informal caregivers in Ontario is 82,500. Accounting for the fact that 29% of people with dementia live alone, this leaves a remaining estimate of 58,575 Ontarians providing care for a person with dementia with whom they reside.
Description of Interventions
The 2 main categories of caregiver-directed interventions examined in this review are respite care and psychosocial interventions. Respite care is defined as a break or relief for the caregiver. In most cases, respite is provided in the home, through day programs, or at institutions (usually 30 days or less). Depending on a caregiver’s needs, respite services will vary in delivery and duration. Respite care is carried out by a variety of individuals, including paid staff, volunteers, family, or friends.
Psychosocial interventions encompass a broad range of interventions and have been classified in various ways in the literature. This review will examine educational, behavioural, dementia-specific, supportive, and coping interventions. The analysis focuses on behavioural interventions, that is, those designed to help the caregiver manage BPSD. As described earlier, BPSD are one of the most challenging aspects of caring for a senior with dementia, causing an increase in caregiver burden. The analysis also examines multicomponent interventions, which include at least 2 of the above-mentioned interventions.
Methods of Evidence-Based Analysis
A comprehensive search strategy was used to identify systematic reviews and randomized controlled trials (RCTs) that examined the effectiveness of interventions for caregivers of dementia patients.
Questions
Section 2.1
Are respite care services effective in supporting the well-being of unpaid caregivers of seniors with dementia in the community?
Do respite care services impact on rates of institutionalization of these seniors?
Section 2.2
Which psychosocial interventions are effective in supporting the well-being of unpaid caregivers of seniors with dementia in the community?
Which interventions reduce the risk for institutionalization of seniors with dementia?
Outcomes of Interest
any quantitative measure of caregiver psychological health, including caregiver burden, depression, quality of life, well-being, strain, mastery (taking control of one’s situation), reactivity to behaviour problems, etc.;
rate of institutionalization; and
cost-effectiveness.
Assessment of Quality of Evidence
The quality of the evidence was assessed as High, Moderate, Low, or Very low according to the GRADE methodology and GRADE Working Group. As per GRADE the following definitions apply:
Summary of Findings
Conclusions in Table 1 are drawn from Sections 2.1 and 2.2 of the report.
Summary of Conclusions on Caregiver-Directed Interventions
There is limited evidence from RCTs that respite care is effective in improving outcomes for those caring for seniors with dementia.
There is considerable qualitative evidence of the perceived benefits of respite care.
Respite care is known as one of the key formal support services for alleviating caregiver burden in those caring for dementia patients.
Respite care services need to be tailored to individual caregiver needs as there are vast differences among caregivers and patients with dementia (severity, type of dementia, amount of informal/formal support available, housing situation, etc.)
There is moderate- to high-quality evidence that individual behavioural interventions (≥ 6 sessions), directed towards the caregiver (or combined with the patient) are effective in improving psychological health in dementia caregivers.
There is moderate- to high-quality evidence that multicomponent interventions improve caregiver psychosocial health and may affect rates of institutionalization of dementia patients.
RCT indicates randomized controlled trial.
Patient-Directed Interventions for Dementia
Objective
The section on patient-directed interventions for dementia is broken down into 4 subsections with the following questions:
3.1 Physical Exercise for Seniors with Dementia – Secondary Prevention
What is the effectiveness of physical exercise for the improvement or maintenance of basic activities of daily living (ADLs), such as eating, bathing, toileting, and functional ability, in seniors with mild to moderate dementia?
3.2 Nonpharmacologic and Nonexercise Interventions to Improve Cognitive Functioning in Seniors With Dementia – Secondary Prevention
What is the effectiveness of nonpharmacologic interventions to improve cognitive functioning in seniors with mild to moderate dementia?
3.3 Physical Exercise for Delaying the Onset of Dementia – Primary Prevention
Can exercise decrease the risk of subsequent cognitive decline/dementia?
3.4 Cognitive Interventions for Delaying the Onset of Dementia – Primary Prevention
Does cognitive training decrease the risk of cognitive impairment, deterioration in the performance of basic ADLs or instrumental activities of daily living (IADLs),1 or incidence of dementia in seniors with good cognitive and physical functioning?
Clinical Need: Target Population and Condition
Secondary Prevention2
Exercise
Physical deterioration is linked to dementia. This is thought to be due to reduced muscle mass leading to decreased activity levels and muscle atrophy, increasing the potential for unsafe mobility while performing basic ADLs such as eating, bathing, toileting, and functional ability.
Improved physical conditioning for seniors with dementia may extend their independent mobility and maintain performance of ADL.
Nonpharmacologic and Nonexercise Interventions
Cognitive impairments, including memory problems, are a defining feature of dementia. These impairments can lead to anxiety, depression, and withdrawal from activities. The impact of these cognitive problems on daily activities increases pressure on caregivers.
Cognitive interventions aim to improve these impairments in people with mild to moderate dementia.
Primary Prevention3
Exercise
Various vascular risk factors have been found to contribute to the development of dementia (e.g., hypertension, hypercholesterolemia, diabetes, overweight).
Physical exercise is important in promoting overall and vascular health. However, it is unclear whether physical exercise can decrease the risk of cognitive decline/dementia.
Nonpharmacologic and Nonexercise Interventions
Having more years of education (i.e., a higher cognitive reserve) is associated with a lower prevalence of dementia in crossectional population-based studies and a lower incidence of dementia in cohorts followed longitudinally. However, it is unclear whether cognitive training can increase cognitive reserve or decrease the risk of cognitive impairment, prevent or delay deterioration in the performance of ADLs or IADLs or reduce the incidence of dementia.
Description of Interventions
Physical exercise and nonpharmacologic/nonexercise interventions (e.g., cognitive training) for the primary and secondary prevention of dementia are assessed in this review.
Evidence-Based Analysis Methods
A comprehensive search strategy was used to identify systematic reviews and RCTs that examined the effectiveness, safety and cost effectiveness of exercise and cognitive interventions for the primary and secondary prevention of dementia.
Questions
Section 3.1: What is the effectiveness of physical exercise for the improvement or maintenance of ADLs in seniors with mild to moderate dementia?
Section 3.2: What is the effectiveness of nonpharmacologic/nonexercise interventions to improve cognitive functioning in seniors with mild to moderate dementia?
Section 3.3: Can exercise decrease the risk of subsequent cognitive decline/dementia?
Section 3.4: Does cognitive training decrease the risk of cognitive impairment, prevent or delay deterioration in the performance of ADLs or IADLs, or reduce the incidence of dementia in seniors with good cognitive and physical functioning?
Assessment of Quality of Evidence
The quality of the evidence was assessed as High, Moderate, Low, or Very low according to the GRADE methodology. As per GRADE the following definitions apply:
Summary of Findings
Table 2 summarizes the conclusions from Sections 3.1 through 3.4.
Summary of Conclusions on Patient-Directed Interventions*
Previous systematic review indicated that “cognitive training” is not effective in patients with dementia.
A recent RCT suggests that CST (up to 7 weeks) is effective for improving cognitive function and quality of life in patients with dementia.
Regular leisure time physical activity in midlife is associated with a reduced risk of dementia in later life (mean follow-up 21 years).
Regular physical activity in seniors is associated with a reduced risk of cognitive decline (mean follow-up 2 years).
Regular physical activity in seniors is associated with a reduced risk of dementia (mean follow-up 6–7 years).
Evidence that cognitive training for specific functions (memory, reasoning, and speed of processing) produces improvements in these specific domains.
Limited inconclusive evidence that cognitive training can offset deterioration in the performance of self-reported IADL scores and performance assessments.
1° indicates primary; 2°, secondary; CST, cognitive stimulation therapy; IADL, instrumental activities of daily living; RCT, randomized controlled trial.
Benefit/Risk Analysis
As per the GRADE Working Group, the overall recommendations consider 4 main factors:
the trade-offs, taking into account the estimated size of the effect for the main outcome, the confidence limits around those estimates, and the relative value placed on the outcome;
the quality of the evidence;
translation of the evidence into practice in a specific setting, taking into consideration important factors that could be expected to modify the size of the expected effects such as proximity to a hospital or availability of necessary expertise; and
uncertainty about the baseline risk for the population of interest.
The GRADE Working Group also recommends that incremental costs of health care alternatives should be considered explicitly alongside the expected health benefits and harms. Recommendations rely on judgments about the value of the incremental health benefits in relation to the incremental costs. The last column in Table 3 reflects the overall trade-off between benefits and harms (adverse events) and incorporates any risk/uncertainty (cost-effectiveness).
Overall Summary Statement of the Benefit and Risk for Patient-Directed Interventions*
Economic Analysis
Budget Impact Analysis of Effective Interventions for Dementia
Caregiver-directed behavioural techniques and patient-directed exercise programs were found to be effective when assessing mild to moderate dementia outcomes in seniors living in the community. Therefore, an annual budget impact was calculated based on eligible seniors in the community with mild and moderate dementia and their respective caregivers who were willing to participate in interventional home sessions. Table 4 describes the annual budget impact for these interventions.
Annual Budget Impact (2008 Canadian Dollars)
Assumed 7% prevalence of dementia aged 65+ in Ontario.
Assumed 8 weekly sessions plus 4 monthly phone calls.
Assumed 12 weekly sessions plus biweekly sessions thereafter (total of 20).
Assumed 2 sessions per week for first 5 weeks. Assumed 90% of seniors in the community with dementia have mild to moderate disease. Assumed 4.5% of seniors 65+ are in long-term care, and the remainder are in the community. Assumed a rate of participation of 60% for both patients and caregivers and of 41% for patient-directed exercise. Assumed 100% compliance since intervention administered at the home. Cost for trained staff from Ministry of Health and Long-Term Care data source. Assumed cost of personal support worker to be equivalent to in-home support. Cost for recreation therapist from Alberta government Website.
Note: This budget impact analysis was calculated for the first year after introducing the interventions from the Ministry of Health and Long-Term Care perspective using prevalence data only. Prevalence estimates are for seniors in the community with mild to moderate dementia and their respective caregivers who are willing to participate in an interventional session administered at the home setting. Incidence and mortality rates were not factored in. Current expenditures in the province are unknown and therefore were not included in the analysis. Numbers may change based on population trends, rate of intervention uptake, trends in current programs in place in the province, and assumptions on costs. The number of patients was based on patients likely to access these interventions in Ontario based on assumptions stated below from the literature. An expert panel confirmed resource consumption.

7.  Social Isolation in Community-Dwelling Seniors 
Executive Summary
In early August 2007, the Medical Advisory Secretariat began work on the Aging in the Community project, an evidence-based review of the literature surrounding healthy aging in the community. The Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the ministry’s newly released Aging at Home Strategy.
After a broad literature review and consultation with experts, the secretariat identified 4 key areas that strongly predict an elderly person’s transition from independent community living to a long-term care home. Evidence-based analyses have been prepared for each of these 4 areas: falls and fall-related injuries, urinary incontinence, dementia, and social isolation. For the first area, falls and fall-related injuries, an economic model is described in a separate report.
Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/mas_about.html, to review these titles within the Aging in the Community series.

The Falls/Fractures Economic Model in Ontario Residents Aged 65 Years and Over (FEMOR)
Objective of the Evidence-Based Analysis
The objective was to systematically review interventions aimed at preventing or reducing social isolation and loneliness in community-dwelling seniors, that is, persons ≥ 65 years of age who are not living in long-term care institutions. The analyses focused on the following questions:
Are interventions to reduce social isolation and/or loneliness effective?
Do these interventions improve health, well-being, and/or quality of life?
Do these interventions impact on independent community living by delaying or preventing functional decline or disability?
Do the interventions impact on health care utilization, such as physician visits, emergency visits, hospitalization, or admission to long-term care?
Background: Target Population and Condition
Social and family relationships are a core element of quality of life for seniors, and these relationships have been ranked second, next to health, as the most important area of life. Several related concepts—reduced social contact, being alone, isolation, and feelings of loneliness—have all been associated with a reduced quality of life in older people. Social isolation and loneliness have also been associated with a number of negative outcomes such as poor health, maladaptive behaviour, and depressed mood. Higher levels of loneliness have also been associated with increased likelihood of institutionalization.
Note: It is recognized that the terms “senior” and “elderly” carry a range of meanings for different audiences; this report generally uses the former, but the terms are treated here as essentially interchangeable.
Methods of the Evidence-Based Analysis
The scientific evidence base was evaluated through a systematic literature review. The literature searches were conducted with several computerized bibliographic databases for literature published between January 1980 and February 2008. The search was restricted to English-language reports on human studies and excluded letters, comments and editorials, and case reports. Journal articles eligible for inclusion in the review included those that reported on single, focused interventions directed towards or evaluating social isolation or loneliness; included, in whole or in part, community-dwelling seniors (≥ 65 years); included some quantitative outcome measure on social isolation or loneliness; and included a comparative group. Assessments of current practices were obtained through consultations with various individuals and agencies including the Ontario Community Care Access Centres and the Ontario Assistive Devices Program. An Ontario-based budget impact was also assessed for the identified effective interventions for social isolation.
Findings
A systematic review of the published literature focusing on interventions for social isolation and loneliness in community-dwelling seniors identified 11 quantitative studies. The studies involved European or American populations with diverse recruitment strategies, intervention objectives, and limited follow-up, with cohorts from 10 to 15 years ago involving mainly elderly women less than 75 years of age. The studies involved 2 classes of interventions: in-person group support activities and technology-assisted interventions. These were delivered to diverse targeted groups of seniors such as those with mental distress, physically inactive seniors, low-income groups, and informal caregivers. The interventions were primarily focused on behaviour-based change. Modifying factors (client attitude or preference) and process issues (targeting methods of at-risk subjects, delivery methods, and settings) influenced intervention participation and outcomes.
Both classes of interventions were found to reduce social isolation and loneliness in seniors. Social support groups were found to effectively decrease social isolation for seniors on wait lists for senior apartments and those living in senior citizen apartments. Community-based exercise programs featuring health and wellness for physically inactive community-dwelling seniors also effectively reduced loneliness. Rehabilitation for mild/moderate hearing loss was effective in improving communication disabilities and reducing loneliness in seniors. Interventions evaluated for informal caregivers of seniors with dementia, however, had limited effectiveness for social isolation or loneliness.
Research into interventions for social isolation in seniors has not been broadly based, relative to the diverse personal, social, health, economic, and environmentally interrelated factors potentially affecting isolation. Although rehabilitation for hearing-related disability was evaluated, the systematic review did not locate research on interventions for other common causes of aging-related disability and loneliness, such as vision loss or mobility declines. Despite recent technological advances in e-health or telehealth, controlled studies evaluating technology-assisted interventions for social isolation have examined only basic technologies such as phone- or computer-mediated support groups.
Conclusions
Although effective interventions were identified for social isolation and loneliness in community-dwelling seniors, they were directed at specifically targeted groups and involved only a few of the many potential causes of social isolation. Little research has been directed at identifying effective interventions that influence the social isolation and other burdens imposed upon caregivers, in spite of the key role that caregivers assume in caring for seniors. The evidence on technology-assisted interventions and their effects on the social health and well-being of seniors and their caregivers is limited, but increasing demand for home health care and the need for efficiencies warrant further exploration. Interventions for social isolation in community-dwelling seniors need to be researched more broadly in order to develop effective, appropriate, and comprehensive strategies for at-risk populations.

8.  The Risk of Fractures Associated with Thiazolidinediones: A Self-controlled Case-Series Study 
PLoS Medicine  2009;6(9):e1000154.
Ian Douglas and colleagues analyze records from the UK General Practice Research Database, and find that among individuals prescribed thiazolidinediones who develop a fracture, fractures are more common during periods of thiazolidinedione exposure than unexposed periods.
Background
The results of clinical trials have suggested that the thiazolidinedione antidiabetic agents rosiglitazone and pioglitazone are associated with an increased risk of fractures, but such studies had limited power. The increased risk in these trials appeared to be limited to women and mainly involved fractures of the arm, wrist, hand, or foot: risk patterns that could not be readily explained. Our objective was to further investigate the risk of fracture associated with thiazolidinedione use.
Methods and Findings
The self-controlled case-series design was used to compare rates of fracture during thiazolidinedione exposed and unexposed periods and thus estimate within-person rate ratios. We used anonymised primary care data from the United Kingdom General Practice Research Database (GPRD). All patients aged 40 y or older with a recorded fracture and at least one prescription for a thiazolidinedione were included (n = 1,819). We found a within-person rate ratio of 1.43 (95% confidence interval [CI] 1.25–1.62) for fracture at any site comparing exposed with unexposed periods among patients prescribed any thiazolidinedione. This association was similar in men and women and in patients treated with either rosiglitazone or pioglitazone. The increased risk was also evident at a range of fracture sites, including hip, spine, arm, foot, wrist, or hand. The risk increased with increasing duration of thiazolidinedione exposure: rate ratio 2.00 (95% CI 1.48–2.70) for 4 y or more of exposure.
Conclusion
Within individuals who experience a fracture, fracture risk is increased during periods of exposure to thiazolidinediones (both rosiglitazone and pioglitazone) compared with unexposed periods. The increased risk is observed in both men and women and at a range of fracture sites. The risk also increases with longer duration of use.

Editors' Summary
Background
Worldwide, nearly 250 million people have diabetes and this number is increasing rapidly, particularly in developing countries. Diabetes is a chronic disease characterized by dangerous amounts of sugar (glucose) in the blood. Blood-sugar levels are normally controlled by insulin, a hormone that the pancreas releases when blood-sugar levels rise after eating (the digestion of food produces glucose). Blood-sugar control fails in people with diabetes because they make no insulin (type 1 diabetes) or because the fat cells and muscle cells that usually respond to insulin by removing sugar from the blood have become insulin insensitive (type 2 diabetes). Type 1 diabetes is treated with insulin injections; type 2 diabetes—the most common type of diabetes—is controlled with diet, exercise, and antidiabetic pills, drugs that help the pancreas make more insulin (for example, sulfonylureas) or that make cells more sensitive to insulin (for example, thiazolidinediones). Long-term complications of diabetes include kidney failure, blindness, and nerve damage, and an increased risk of developing cardiovascular problems, including heart disease and strokes.
Why Was This Study Done?
Thiazolidinediones are widely used to treat type 2 diabetes but, worryingly, these drugs seem to increase people's risk of developing cardiovascular problems. In addition, they may increase the risk of bone fractures although the evidence for this particular association is limited. Given the large number of people with diabetes, it is important to understand the benefits and risks of thiazolidinedione treatment of diabetes as fully as possible. In this self-controlled case-series study, therefore, the researchers investigate the risk of fracture associated with the use of rosiglitazone and pioglitazone (two thiazolidinedione antidiabetic agents). A “self-controlled case-series study” compares how often an event (in this case, a fracture) occurs (the event's “rate”) in a population of individuals during a period of time when the individuals are not exposed to a medical intervention (in this case, treatment with thiazolidinediones) to its rate during a period when they are exposed to the intervention. Because each person acts as their own control, this study design helps to eliminate the possibility that unrecognized characteristics that vary between people (“confounders”) are responsible for differences in the event rate rather than the intervention itself.
What Did the Researchers Do and Find?
The researchers identified 1,819 people aged 40 years or older with a recorded fracture and at least one prescription for a thiazolidinedione by searching the UK General Practice Research Database, which contains personal and health data for more than 6 million UK residents. They compared these people's fracture rate during periods when they were taking a thiazolidinedione to their fracture rate when they weren't taking one of these drugs. After adjusting for age (age is a potential confounder because the risk of fractures increases with age and all the patients were older during their exposed period than during their unexposed period), the rate ratio for fracture at any site in patients during thiazolidinedione-exposed periods compared with thiazolidinedione-unexposed periods was 1.43. That is, nearly one and half times as many fractures occurred when people were taking thiazolidinediones than when they were not taking these drugs. The association between taking thiazolidinediones and the risk of fracture was similar in men and women and at several fracture sites but increased with the length of thiazolidinedione exposure.
What Do These Findings Mean?
These findings suggest that taking thiazolidinediones is associated with an increased risk of fracture at a wide range of sites in both men and women. They also suggest that the risk of fracture increases with treatment duration. These findings do not prove that thiazolidinediones cause fractures because, despite the self-controlled case-series design of this study, it remains possible that the people who have fractures share some unknown characteristic that affects their chances of breaking a bone. The accuracy of the findings is also dependent on the quality of the data in the General Practice Research Database. Nonetheless, these results are in keeping with the findings of clinical trials and other observational studies, suggesting they represent a real effect of treatment with thiazolidinediones. Although it is not clear yet how thiazolidinediones weaken bones, these findings need to be included in the ongoing debate about the risks and benefits of the treatment of type 2 diabetes with thiazolidinediones.

9.  Benzodiazepines and hip fractures in elderly people: case-control study 
BMJ : British Medical Journal  2001;322(7288):704-708.
Objective
To determine whether benzodiazepines are associated with an increased risk of hip fracture.
Design
Case-control study.
Participants
All incident cases of hip fracture not related to traffic accidents or cancer in patients over 65 years of age. 245 cases were matched to 817 controls.
Setting
Emergency department of a university hospital.
Main outcome measures
Exposure to benzodiazepines and other potential risk or protective factors or lifestyle items.
Results
The use of benzodiazepines as determined from questionnaires, medical records, or plasma samples at admission to hospital was not associated with an increased risk of hip fracture (odds ratio 0.9, 95% confidence interval 0.5 to 1.5). Hip fracture was, however, associated with the use of two or more benzodiazepines, as determined from questionnaires or medical records but not from plasma samples. Of the individual drugs, only lorazepam was significantly associated with an increased risk of hip fracture (1.8, 1.1 to 3.1).
Conclusion
Except for lorazepam, the presence of benzodiazepines in plasma was not associated with an increased risk of hip fracture. The method used to ascertain exposure could influence the results of case-control studies.
What is already known on this topicBenzodiazepines increase the risk of elderly people falling in a dose dependent wayTheir role in hip fracture remains disputed, with increased risk sometimes attributed to drugs with a longer half life or those used to induce sleepWhat this study addsBenzodiazepines were not associated with hip fracture either as a group or according to half life or to characterisation as hypnotic or anxiolyticPatients using two or more benzodiazepines may be at higher riskPatients using lorazepam or certain other benzodiazepines may also be at a higher risk of fracture

10.  The effect of Tai Chi Chuan in reducing falls among elderly people: design of a randomized clinical trial in the Netherlands [ISRCTN98840266] 
BMC Geriatrics  2006;6:6.
Background
Falls are a significant public health problem. Thirty to fifty percent of the elderly of 65 years and older fall each year. Falls are the most common type of accident in this age group and can result in fractures and subsequent disabilities, increased fear of falling, social isolation, decreased mobility, and even an increased mortality. Several forms of exercise have been associated with a reduced risk of falling and with a wide range of physiological as well as psychosocial health benefits. Tai Chi Chuan seems to be the most promising form of exercise in the elderly, but the evidence is still controversial.
In this article the design of a randomized clinical trial is presented. The trial evaluates the effect of Tai Chi Chuan on fall prevention and physical and psychological function in older adults.
Methods/Design
270 people of seventy years and older living at home will be identified in the files of the participating general practitioners. People will be asked to participate when meeting the following inclusion criteria: have experienced a fall in the preceding year or suffer from two of the following risk factors: disturbed balance, mobility problems, dizziness, or the use of benzodiazepines or diuretics. People will be randomly allocated to either the Tai Chi Chuan group (13 weeks, twice a week) or the no treatment control group.
The primary outcome measure is the number of new falls, measured with a diary. The secondary outcome measures are balance, fear of falling, blood pressure, heart rate, lung function parameters, physical activity, functional status, quality of life, mental health, use of walking devices, medication, use of health care services, adjustments to the house, severity of fall incidents and subsequent injuries. Process parameters will be measured to evaluate the Tai Chi Chuan intervention. A cost-effectiveness analysis will be carried out alongside the evaluation of the clinical results. Follow-up measurements will be collected at 3, 6 and 12 months after randomization.
Discussion
As far as we know this is the first trial in Europe considering Tai Chi Chuan and fall prevention. This project will answer a pragmatic research question regarding the efficacy of Tai Chi Chuan regarding fall reduction.

11.  Predicting imminent risk for fracture in patients aged 50 or older with osteoporosis using US claims data 
Archives of Osteoporosis  2016;11(1):26.
Summary
Patient characteristics contributing to imminent risk for fracture, defined as risk of near-term fracture within the next 12 to 24 months, have not been well defined. In patients without recent fracture, we identified factors predicting imminent risk for vertebral/nonvertebral fracture, including falls, age, comorbidities, and other potential fall risk factors.
Purpose
Several factors contribute to long-term fracture risk in patients with osteoporosis, including age, bone mineral density, and fracture history. Some patients may be at imminent risk for fracture, defined here as a risk of near-term fracture within 12–24 months. Many patient characteristics contributing to imminent risk for fracture have not been well defined. This case-control study used US commercial and Medicare supplemental insured data for women and men without recent fracture to identify factors associated with imminent risk for fracture.
Methods
Patients included were aged ≥50 with osteoporosis, had a vertebral or nonvertebral fracture claim (index date; fracture group) or no fracture claim (control group) from January 1, 2006, to September 30, 2012, continuously enrolled and without fracture in the 24 months before index. Potential risk factors during the period before fracture were assessed.
Results
Using data from 12 months before fracture, factors significantly associated with imminent risk for fracture were previous falls, older age, poorer health status, specific comorbidities (psychosis, Alzheimer’s disease, central nervous system disease), and other fall risk factors (wheelchair use, psychoactive medication use, mobility impairment). Similar findings were observed with data from 24 months before fracture.
Conclusions
In patients with osteoporosis and no recent fracture, falls, older age, poorer health status, comorbidities, and other potential fall risk factors were predictive of imminent risk for fracture. Identification of factors associated with imminent risk for vertebral/nonvertebral fracture may help identify and risk stratify those patients most in need of immediate and appropriate treatment to decrease fracture risk.

12.  Parkinson’s Disease and Osteoporosis 
Parkinson’s disease (PD) and osteoporosis are two conditions that affect a considerable proportion of the elderly population and have a significant socio-economic impact, which is linked partly to increases in hospital admissions following fractures and partly to increased consumption of drugs.
Reduced walking speed, difficulty walking in tandem, reduced visual acuity and reduced thigh circumference are independent risk factors for fall-related hip fractures. Falls are a major fracture risk factor in elderly people and are the leading cause of emergency department admissions in parkinsonian patients. Falls are a much more frequent occurrence in PD patients than in their healthy peers and the factors that contribute most to this increased risk are older age, longer disease duration, more severe disease (as measured using the Hoehn & Yahr scale), bradykinesia, rigidity, gait disorders, postural instability, the presence of dementia and the presence of atypical parkinsonism. Fractures, obviously correlated with the frequency of falls, are also more common in individuals with PD compared with the age-matched healthy population, and the femur is the most frequent fracture site. A reduced bone mass density (BMD) appears to be a factor correlated with increased fracture risk in parkinsonian subjects. Individuals with PD have lower BMD values than healthy, age-matched controls and this reduction seems to be related to their bodyweight (a low body mass index, BMI), reduced physical activity, disease duration, disease severity (Hoehn and Yahr stage), calcium intake and exposure to sunlight. From a pathophysiological point of view, various factors are implicated in osteoporosis in PD: - immobilisation: this is known to be a factor in bone loss, even though, at present, the precise pathophysiological mechanism by which it might induce osteopenia remains unclear; one hypothesis suggests an increase in osteoclast activity and a suppression of osteoblast activity.- endocrine factors: in addition to reduced levels of GH, ACTH and cortisol in PD patients versus age-matched controls, there also seems to be a vitamin D deficiency. Vitamin D acts not only on bone metabolism but also on various other tissues, including the nervous system.- nutritional factors: weight loss is a factor often present in patients with PD, even early in the disease; however, it is much more marked in the advanced stages of PD, when the cognitive problems, dysphagia and delayed gastric emptying appear. BMD is even lower in PD patients with low bodyweight compared with the overall population of PD patients who, per se, already have a low BMD compared with that of the general population. Low bodyweight and low physical activity are risk factors for low BMD in PD. Fracture risk may be reduced by dietary supplementation of calcium and vitamin D.- iatrogenic factors: a recent study showed that high daily doses of levodopa are associated with an increased fracture risk and this is probably linked to the fact that levodopa increases hyperhomocysteinaemia in subjects with PD.
Given the mortality and morbidity of fractures in the elderly population, and particularly in subjects with PD, it is reasonable to suggest that these patients should be submitted to measurement of vitamin levels (vitamins D, B12 and folate), BMD measurement and assessment of fall risk, and also that preventive measures should be implemented in order to reduce their fracture risk. In the absence of specific guidelines and recommendations on the treatment and prevention of osteoporosis in PD, it currently seems reasonable to follow the existing indications for post-menopausal treatment of osteoporosis, given that the fracture risk profile in PD subjects may differ from that of the general population on account of their increased fall risk, low level of physical activity, reduced vitamin D intake and swallowing difficulties.

13.  Do Sex Differences Exist in Rates of Falls and Fractures in Hutterite, Rural, and Nonrural Populations, Aged 20 to 66 Years? 
Background
Falls and fractures are a major public health concern with an economic impact of more than USD 19 billion per year. Extensive research into the risk of falls and fractures in elderly populations has been performed; however, little is known about fall or fracture risk in younger populations. Additionally, sex- and population-specific (rural versus nonrural) fall and fracture risk may be important in identifying groups most at risk in an effort to develop preventive measures.
Questions/purposes
The purpose of this study was to determine whether sex and population (rural versus nonrural) differences exist in fall and fracture rates.
Methods
Data from 1256 (538 men) participants of the South Dakota Rural Bone Health Study, a population-based cohort study, including those living a rural lifestyle (n = 349 non-Hutterites and 572 Hutterites) and a nonrural lifestyle (n = 335), were used to address our a priori hypotheses. Health histories, physical activity recall, anthropometric measurements, and dual-energy xray absorptiometry measurements of body composition were obtained longitudinally from participants every 18 months for 7.5 years. Falls and fractures were self-reported and fractures were confirmed through medical record review. Incidence rates were calculated as the number of falls or fractures per 1000 person-years and generalized estimating equations determined the association of sex and population group with fall and fractures rates while accounting for the repeated longitudinal measurements on the same person. All models adjusted for age group, percent time in moderate and vigorous physical activity, lean and fat mass, grip strength, and previous diagnosis of osteoarthritis.
Results
Males aged 39 years and younger had a 135% greater fall risk than females in the same age category (p = 0.03), but there was no differences between males and females 40 years of age or older (p = 0.26; age-by-sex interaction, p = 0.05). No sex differences were observed for fracture risk. After controlling for covariates, rural and nonrural individuals fell at higher rates than Hutterites (84% and 50%, respectively, p < 0.001). Additionally, rural individuals fractured at a 72% greater rate than Hutterites after controlling for covariates (p = 0.03).
Conclusions
Sex differences in fall risk among younger individuals along with population differences in fall and fracture rates suggest that sex and lifestyle factors may have an impact on fall and fracture risk. Future studies focusing on sex- and population-specific risk factors are necessary to develop prevention strategies tailored to specific populations.

14.  National outpatient medication profiling: medications associated with outpatient fractures in community-dwelling elderly veterans 
What is already known about this subject
Polypharmacy, to include a subissue of potentially inappropriate prescribing, in community-dwelling elderly is widespread.The objective of this study was to identify the magnitude of problematic outpatient drug prescribing and its potential association as a risk factor for injuries.
What this study adds
This is the first national study of outpatient injuries in elderly veterans.The results are consistent with previous published literature highlighting the risks associated with prescribing central nervous system drugs in the elderly.
Aims
The primary objective of this retrospective case–control study in an elderly veteran population was to assess the impact of specific medications with recognized side-effects that increase the risk of a fall and were prescribed prior to fractures treated in the outpatient setting compared with patients treated for nonspecific chest pain.
Methods
Two national Veterans Health Administration (VHA) databases were used to identify 17 273 unique patients, aged ≥65 years, treated in outpatient settings with a fracture in fiscal year 2005, and for whom we could link to all of their outpatient prescriptions (809 536). For comparison, we identified other elderly patients with outpatient clinic visits for nonspecific chest pain (N = 62 331) for whom we could link with their 2 987 394 outpatient prescriptions. We categorized the fall-related medications as drugs that primarily affect the cardiovascular (CVS), the central nervous (CNS) or the muscular skeletal system (MSS).
Results
Significant differences in the two patient groups occurred in the CNS category. Approximately 41% of the patients with fracture-coded encounters were prescribed CNS drugs compared with 31% of the patients in the comparison group (P < 0.0003). Finally, the use of muscle relaxants in the MSS category was significantly higher in the fracture group than in the nonspecific chest pain group.
Conclusions
Studies using administrative data can foster the development of more proactive pharmacovigilance systems and assist in formulary refinement, particularly in countries with national healthcare systems that have integrated patient data. Particular attention and monitoring of elderly patients taking CNS medications may be important for injury prevention.

15.  Is health-related quality of life associated with the risk of low-energy wrist fracture: a case-control study 
Background
Some risk factors for low-energy wrist fracture have been identified. However, self-reported measures such as health-related quality of life (HRQOL) have not been examined as potential risk factors for wrist fracture. The aims of this study were to compare HRQOL prior to a low-energy wrist fracture in elderly patients (≥ 50 years) with HRQOL in age- and sex-matched controls, and to explore the association between HRQOL and wrist fracture after adjusting for known risk factors for fracture such as age, weight, osteoporosis and falls.
Methods
Patients with a low-energy wrist fracture (n = 181) and age- and sex-matched controls (n = 181) were studied. Shortly after fracture (median 10 days), patients assessed their HRQOL before fracture using the Short Form 36 (SF-36). Statistical tests included t tests and multivariate logistic regression analysis.
Results
Several dimensions of HRQOL were significantly associated with wrist fracture. The direction of the associations with wrist fracture varied between the different sub-dimensions of the SF-36. After controlling for demographic and clinical variables, higher scores on general health (odds ratio (OR) = 1.31, 95% confidence interval (CI) = 1.10–1.56), bodily pain (OR = 1.18, 95% CI = 1.03–1.34) and mental health (OR = 1.39, 95% CI = 1.09–1.79) were related to an increased chance of being a wrist fracture patient rather than a control. In contrast, higher scores on physical role limitation (OR = 0.87, 95% CI = 0.79–0.95) and social function (OR = 0.65, 95% CI 0.53–0.80) decreased this chance. Significant associations with wrist fracture were also found for living alone (OR = 1.91, 95% CI 1.07–3.4), low body mass index (BMI) (OR = 0.92, 95% CI 0.86–0.98), osteoporosis (OR = 3.30, 95% CI 1.67–6.50) and previous falls (OR = 2.01, 95% CI 1.16–3.49).
Conclusion
Wrist fracture patients perceive themselves to be as healthy as the controls before fracture. Our data indicate that patients with favourable and unfavourable HRQOL measures may be at increased risk of wrist fracture.

16.  Leisure Physical Activity and the Risk of Fracture in Men 
PLoS Medicine  2007;4(6):e199.
Background
Data from previous studies are inconsistent, and it is therefore uncertain whether, to what extent, and at what level leisure physical activity influences the risk of osteoporotic fractures in men.
Methods and Findings
A cohort of 2,205 men, 49–51 y of age, was enrolled in a longitudinal, population-based study. Leisure physical activity and other lifestyle habits were established at baseline and at ages 60, 70, 77, and 82 y. During 35 y of follow-up, 482 men had at least one fracture. Cox's proportional hazards regression was used to determine hazard ratios (HRs) of fracture associated with time-dependent physical activity habits and covariates. Men with a sedentary lifestyle (HR 2.56, 95% confidence interval 1.55–4.24) or men who walked or bicycled only for pleasure (HR 1.61, 95% confidence interval 1.10–2.36) had an increased adjusted risk of hip fracture compared with men who participated in regular sports activities for at least 3 h/wk. At the end of follow-up, 8.4% of the men with a high physical activity, 13.3% of the men with a medium physical activity, and 20.5% of the men with a low physical activity had suffered a hip fracture. According to the estimation of population-attributable risk, one third of all hip fractures could be prevented by participation in regular sports activities. High activity also conferred a reduced overall fracture risk.
Conclusions
Our data indicate that regular sports activities can reduce the risk of fractures in older men.
From a large cohort study with 35 years of follow-up, Michaelsson and colleagues conclude that regular sport activities can reduce the risk of fractures in older men.
Editors' Summary
Background.
One of the hazards of old age is that the bones become less dense—and therefore weaker—so when an elderly person falls, the result is often a broken bone. As many as half of all women and a quarter of men older than 50 y will break a bone because of this, and the consequences can be serious, particularly if the hip is broken. The thinning of bones, which is known as osteoporosis, does affect all people as they age, but the degree to which it occurs varies greatly between individuals. A priority area for medical research is finding ways in which osteoporosis can be reduced, with the aim of improving the lives of older people and reducing their risk of “osteoporotic fractures.” It is known that genetic and environmental factors can both play a part in how rapidly osteoporosis develops, but it is generally agreed that personal lifestyle factors are also important. Osteoporosis develops over many years; in most people bone density starts to decline after the age of about 30 y. Preventive action should therefore begin early.
Most research so far has focused on women, who are more at risk as the thinning of their bones increases after the menopause. (Indeed osteoporosis has sometimes been wrongly described as a “woman's disease.”) It is now accepted that women who are more physically active reduce the rate of decline in their bone density and, as a result, are less likely to break bones when they are elderly. There has been little research in men and the results have not been consistent.
Why Was This Study Done?
In order to provide better evidence as to whether men who do more physical activity have fewer osteoporotic fractures than those with lower activity levels, the researchers wanted to complete a study that was larger and was conducted over a longer period of time than previous research.
What Did the Researchers Do and Find?
Between 1970 and 1973, the researchers invited all those men living in Uppsala, Sweden, who were aged between 49 and 51 y to participate in a health survey. Most of them (2,205) agreed to do so. When the study began, they were asked questions about the amount of physical activity they took outside working hours. They were asked the same questions again when they were aged 60, 70, 77, and 82 y. A record was also kept of the number of fractures the men had suffered during the 35-y study period. (Although some of the men died before the end of the study, about half were still alive at the end.) On the basis of the answers to the questions on physical activity at the start of the study, the researchers divided the men into three categories: those whose lifestyle was considered to be “sedentary,” those whose leisure activities included some walking and cycling, and those who participated in sports for at least 3 h a week. These were referred to as the low, medium, and high activity groups. Over the 35-y period, 428 men had at least one fracture and 134 broke a hip, but there were big differences between the groups—20% of the low-activity men had fractures compared with 13% of those with medium activity and only 8% of those in the high-activity group. In particular, the chance of having a hip fracture was reduced by increased activity.
What Do These Findings Mean?
Taking exercise reduces the risk of an osteoporotic fracture. Participating in sports seems to be particularly effective; the researchers calculate that one-third of fractures could be prevented if men could be persuaded to take part in sports regularly. The researchers do note that the very best evidence always comes from studies where people are assigned at random to receive a particular “treatment” (in this case, it would be exercise) and are compared with others who did not receive the treatment. This is known as a “randomized controlled trial.” Such a trial would be difficult, if not impossible, to organize on this topic, and the approach adopted by the researchers, which is known as a “cohort study,” does provide very strong evidence. There are many other benefits from increased exercise (for example, in reducing the risk of heart attacks and strokes), and most governments are now promoting sports and other active leisure pursuits. This study adds further weight to support such policies.

17.  Percutaneous Vertebroplasty for Treatment of Painful Osteoporotic Vertebral Compression Fractures 
Executive Summary
Objective of Analysis
The objective of this analysis is to examine the safety and effectiveness of percutaneous vertebroplasty for treatment of osteoporotic vertebral compression fractures (VCFs) compared with conservative treatment.
Clinical Need and Target Population
Osteoporosis and associated fractures are important health issues in ageing populations. Vertebral compression fracture secondary to osteoporosis is a cause of morbidity in older adults. VCFs can affect both genders, but are more common among elderly females and can occur as a result of a fall or a minor trauma. The fracture may occur spontaneously during a simple activity such as picking up an object or rising up from a chair. Pain originating from the fracture site frequently increases with weight bearing. It is most severe during the first few weeks and decreases with rest and inactivity.
Traditional treatment of painful VCFs includes bed rest, analgesic use, back bracing and muscle relaxants. The comorbidities associated with VCFs include deep venous thrombosis, acceleration of osteopenea, loss of height, respiratory problems and emotional problems due to chronic pain.
Percutaneous vertebroplasty is a minimally invasive surgical procedure that has gained popularity as a new treatment option in the care for these patients. The technique of vertebroplasty was initially developed in France to treat osteolytic metastasis, myeloma, and hemangioma. The indications were further expanded to painful osteoporotic VCFs and subsequently to treatment of asymptomatic VCFs.
The mechanism of pain relief, which occurs within minutes to hours after vertebroplasty, is still not known. Pain pathways in the surrounding tissue appear to be altered in response to mechanical, chemical, vascular, and thermal stimuli after the injection of the cement. It has been suggested that mechanisms other than mechanical stabilization of the fracture, such as thermal injury to the nerve endings, results in immediate pain relief.
Percutaneous Vertebroplasty
Percutaneous vertebroplasty is performed with the patient in prone position and under local or general anesthesia. The procedure involves fluoroscopic imaging to guide the injection of bone cement into the fractured vertebral body to support the fractured bone. After injection of the cement, the patient is placed in supine position for about 1 hour while the cement hardens.
Cement leakage is the most frequent complication of vertebroplasty. The leakages may remain asymptomatic or cause symptoms of nerve irritation through compression of nerve roots. There are several reports of pulmonary cement embolism (PCE) following vertebroplasty. In some cases, the PCE may remain asymptomatic. Symptomatic PCE can be recognized by their clinical signs and symptoms such as chest pain, dyspnea, tachypnea, cyanosis, coughing, hemoptysis, dizziness, and sweating.
Research Methods
Literature Search
A literature search was performed on Feb 9, 2010 using OVID MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, EMBASE, the Cumulative Index to Nursing & Allied Health Literature (CINAHL), the Cochrane Library, and the International Agency for Health Technology Assessment (INAHTA) for studies published from January 1, 2005 to February 9, 2010.
Studies were initially reviewed by titles and abstracts. For those studies meeting the eligibility criteria, full-text articles were obtained and reviewed. Reference lists were also examined for any additional relevant studies not identified through the search. Articles with an unknown eligibility were reviewed with a second clinical epidemiologist and then a group of epidemiologists until consensus was established. Data extraction was carried out by the author.
Inclusion Criteria
Study design: Randomized controlled trials (RCTs) comparing vertebroplasty with a control group or other interventions

Results of Evidence-Based Analysis
A systematic search yielded 168 citations. The titles and the abstracts of the citations were reviewed and full text of the identified citations was retrieved for further consideration. Upon review of the full publications and applying the inclusion and exclusion criteria, 5 RCTs were identified. Of these, two compared vertebroplasty with sham procedure, two compared vertebroplasty with conservative treatment, and one compared vertebroplasty with balloon kyphoplasty.
Randomized Controlled Trials
Recently, the results of two blinded randomized placebo-controlled trials of percutaneous vertebroplasty were reported. These trials, providing the highest quality of evidence available to date, do not support the use of vertebroplasty in patients with painful osteoporotic vertebral compression fractures. Based on the results of these trials, vertebroplasty offer no additional benefit over usual care and is not risk free.
In these trials the treatment allocation was blinded to the patients and outcome assessors. The control group received a sham procedure simulating vertebroplasty to minimize the effect of expectations and to reduce the potential for bias in self-reporting of outcomes. Both trials applied stringent exclusion criteria so that the results are generalizable to the patient populations that are candidates for vertebroplasty. In both trials vertebroplasty procedures were performed by highly skilled interventionists. Multiple valid outcome measures including pain, physical, mental, and social function were employed to test the between group differences in outcomes.
Prior to these two trials, there were two open randomized trials in which vertebroplasty was compared with conservative medical treatment. In the first randomized trial, patients were allowed to cross over to the other arm and had to be stopped after two weeks due to the high numbers of patients crossing over. The other study did not allow cross over and recently published the results of 12 months follow-up.
The following is the summary of the results of these 4 trials:
Two blinded RCTs on vertebroplasty provide the highest level of evidence available to date. Results of these two trials are supported by findings of an open randomized trial with 12 months follow-up. Blinded RCTs showed:
No significant differences in pain scores of patients who received vertebroplasty and patients who received a sham procedure as measured at 3 days, 2 weeks and 1 month in one study and at 1 week, 1 month, 3 months, and 6 months in the other.
The observed differences in pain scores between the two groups were neither statistically significant nor clinically important at any time points.
The above findings were consistent with the findings of an open RCT in which patients were followed for 12 months. This study showed that improvement in pain was similar between the two groups at 3 months and were sustained to 12 months.
In the blinded RCTs, physical, mental, and social functioning were measured at the above time points using 4-5 of the following 7 instruments: RDQ, EQ-5D, SF-36 PCS, SF-36 MCS, AQoL, QUALEFFO, SOF-ADL
There were no significant differences in any of these measures between patients who received vertebroplasty and patients who received a sham procedure at any of the above time points (with a few exceptions in favour of control intervention).
These findings were also consistent with the findings of an open RCT which demonstrated no significant between group differences in scores of ED-5Q, SF-36 PCS, SF 36 MCS, DPQ, Barthel, and MMSE which measure physical, mental, and social functioning (with a few exceptions in favour of control intervention).
One small (n=34) open RCT with a two week follow-up detected a significantly higher improvement in pain scores at 1 day after the intervention in vertebroplasty group compared with conservative treatment group. However, at 2 weeks follow-up, this difference was smaller and was not statistically significant.
Conservative treatment was associated with fewer clinically important complications
Risk of new VCFs following vertebroplasty was higher than those in conservative treatment but it requires further investigation.

18.  Association of polypharmacy with fall-related fractures in older Taiwanese people: age- and gender-specific analyses 
BMJ Open  2014;4(3):e004428.
Objective
To elucidate the associations between polypharmacy and age- and gender-specific risks of admission for fall-related fractures.
Design
Nested case–control study.
Setting
This analysis was randomly selected from all elderly beneficiaries in 2007–2008, and represents some 30% of the whole older insurers using Taiwan's National Health Insurance Research Database.
Participants
We identified 5933 cases newly admitted for fall-related fractures during 2007–2008, and 29 665 random controls free from fracture.
Primary and secondary outcome measures
Polypharmacy was defined as the use of fall-related drugs of four or more categories of medications and prescribed related to fall within a 1-year period. Logistic regression models were employed to estimate the ORs and related 95% CIs. The interaction of polypharmacy with age and sex was assessed separately.
Results
Compared with those who consumed no category of medication, older people who consumed 1, 2, 3 and ≥4 categories of medications were all at significantly increased odds of developing fall-related fractures, with a significant dose–gradient pattern (β=0.7953; p for trend <0.0001). There were significant interactions between polypharmacy and age, but no significant interactions between polypharmacy and gender. The dose–gradient relationship between number of medications category and risk of fall-related fractures was more obvious in women than in men (β=0.1962 vs β=0.1873). Additionally, it was most evident in older people aged 75–84 years (β=0.2338).
Conclusions
This population-based study in Taiwan confirms the link between polypharmacy and increased risk of fall-related fractures in older people; and highlights that elderly women and older people aged 75–84 years will be the targeted participants for further prevention from fall-related fractures caused by polypharmacy.

19.  P22 - Cognitive Impairment in Hip Fracture Patients 
Introduction:
Proximal femur fractures are the most frequent traumatic skeletal lesions. Despite improved understanding of the risk factors for and means of preventing these fractures, their frequency continues to increase. In Italy there are estimated to be more than 80000 new proximal femur fracture cases every year. These fractures are closely correlated with osteoporosis and are therefore more frequent in the elderly population. Indeed, other fracture risk factors are age and falls. Cognitive decline is one of the intrinsic risk factors for falling as it influences postural control and lower limb muscle strength.
Hip fracture itself is an event capable of triggering a progressive cognitive decline; the incidence of this ranges from 16% to 62% and it is associated with increased morbidity and mortality. The aim of this study was to describe the association between cognitive decline and proximal femur fractures.
Materials and methods:
As part of Indaco 2, an epidemiological survey proposed by SIOT (the Italian Society of Orthopaedics and Traumatology), data were collected relating to 7355 patients attending over 100 orthopaedics and traumatology clinics throughout Italy, recruited over a 6-month period. A questionnaire was administered that, as well as covering various aspects of the patient’s history, also included the Short Portable Mental Status Questionnaire(SPMSQ). This instrument is made up of 10 items that assess the patient’s cognitive abilities.
Results:
From the 7355 questionnaires collected, we excluded those referring to patients under the age of 65 years, this parameter being a criterion for exclusion from the study; we also excluded those with an incomplete SPMSQ. We then excluded, from the remaining 6294 questionnaires, those that failed to provide anamnestic data on the femur fracture. Therefore, the final analysis was performed on 6285 patients, who had a mean age of 77 years (±7.55).
The patients with a femur fracture totalled 2877 and their mean age was 80.3 years (±7.55). The fracture-free patients numbered 3408, and had a mean age of 74.2 years (±6.32). For the final analysis, we dichotomised the SPMSQ variable, thus forming two groups: one comprising patients with normal to mildly impaired cognitive status, and the other patients with moderately to severely impaired cognitive status.
In the group of fracture patients, the SPMSQ showed normal to mildly impaired cognitive status in 67% of the patients, who had a mean age of 78.28 years (±7.2), and moderately to severely impaired cognitive status in 33%, who had a mean age of 84.41 years (±6.49). In the fracture-free population, on the other hand, 90.75% of the patients, with a mean age of 73.64 years (±6.03), showed normal to mildly impaired cognitive status, while only 9.25%, with a mean age of 79.64 years (±6.56), showed moderately to severely impaired cognition. The difference in cognitive status between the two groups (fracture and fracture-free) was statistically significant (p< 0.0001), even after adjusting for the age of the patients.
Conclusions:
The results of our epidemiological study confirm that cognitive status is more impaired in patients with fractures compared with fracture-free subjects, even after adjusting for age. However, the question of whether cognitive decline was the cause of, or secondary to, the fracture it remains to be established.

21.  Effect of a Nutrition Supplement and Physical Activity Program on Pneumonia and Walking Capacity in Chilean Older People: A Factorial Cluster Randomized Trial 
PLoS Medicine  2011;8(4):e1001023.
Alan Dangour and colleagues report results from the CENEX (Cost-effectiveness Evaluation of a Nutritional supplement and EXercise program for older people) trial, which evaluates a nutritional and exercise program aiming to prevent pneumonia and physical decline in Chilean people.
Background
Ageing is associated with increased risk of poor health and functional decline. Uncertainties about the health-related benefits of nutrition and physical activity for older people have precluded their widespread implementation. We investigated the effectiveness and cost-effectiveness of a national nutritional supplementation program and/or a physical activity intervention among older people in Chile.
Methods and Findings
We conducted a cluster randomized factorial trial among low to middle socioeconomic status adults aged 65–67.9 years living in Santiago, Chile. We randomized 28 clusters (health centers) into the study and recruited 2,799 individuals in 2005 (∼100 per cluster). The interventions were a daily micronutrient-rich nutritional supplement, or two 1-hour physical activity classes per week, or both interventions, or neither, for 24 months. The primary outcomes, assessed blind to allocation, were incidence of pneumonia over 24 months, and physical function assessed by walking capacity 24 months after enrolment. Adherence was good for the nutritional supplement (∼75%), and moderate for the physical activity intervention (∼43%). Over 24 months the incidence rate of pneumonia did not differ between intervention and control clusters (32.5 versus 32.6 per 1,000 person years respectively; risk ratio = 1.00; 95% confidence interval 0.61–1.63; p = 0.99). In intention-to-treat analysis, after 24 months there was a significant difference in walking capacity between the intervention and control clusters (mean difference 33.8 meters; 95% confidence interval 13.9–53.8; p = 0.001). The overall cost of the physical activity intervention over 24 months was US$164/participant; equivalent to US$4.84/extra meter walked. The number of falls and fractures was balanced across physical activity intervention arms and no serious adverse events were reported for either intervention.
Conclusions
Chile's nutritional supplementation program for older people is not effective in reducing the incidence of pneumonia. This trial suggests that the provision of locally accessible physical activity classes in a transition economy population can be a cost-effective means of enhancing physical function in later life.

Editors' Summary
Background
By 2050, about a quarter of the world's population will be aged 60 years or over, with Asia and Latin America experiencing the most dramatic increases in the proportion of older people. For example, in Chile, which has recently undergone rapid demographic transition, the proportion of the population aged 60 years or over has increased from 8% to 12% over the past 25 years.
Current global policy initiatives that promote healthy ageing include an emphasis on adequate nutrient intakes, as longitudinal studies (conducted in high-income countries) suggest that achieving nutritional sufficiency and maintaining moderate levels of physical activity both decrease risk of mortality by preserving immune function and lean body mass and so reduce the numerous risk factors for disability and chronic disease in later life. Such interventions may also decrease the risk of infection, particularly pneumonia, a common cause of death in older people. However, older people in low- and middle-income countries frequently have diets with insufficient calories (energy) and/or micronutrients.
Why Was This Study Done?
Currently, there is no high-quality evidence to support the benefits of improved nutrition and increased physical activity levels from low-income or transition economies, where the ongoing demographic trends suggest that the needs are greatest. National policies aimed at preserving health and function in older people with interventions such as cash-transfers and provision of “food baskets” are often used in Latin American countries, such as Chile, but are rarely formally evaluated. Therefore, the purpose of this study (the Cost-effectiveness Evaluation of a Nutritional supplement and EXercise program for older people—CENEX) was to evaluate Chile's national nutritional supplementation program and/or physical exercise, to investigate whether this program prevented pneumonia and physical functional decline in older people in Santiago, and also to investigate whether these interventions were cost-effective.
What Did the Researchers Do and Find?
The researchers randomly allocated 28 participating health centers in Santiago, Chile, into one of four arms: (1) nutritional supplementation; (2) nutritional supplementation+physical activity; (3) physical activity alone; (4) control. From May to December 2005, 2,799 eligible adults aged 65–67.9 years and living in low to middle socioeconomic circumstances, who attended each health center, were recruited into the study and received the allocated intervention—daily micronutrient-rich nutritional supplement, or two 1-hour physical activity classes per week, or both interventions or neither—for 24 months. The researchers did not know the allocation arm of each patient and over the course of the study assessed the incidence of pneumonia (viral and bacterial as based on diagnosis at the health center or hospital) and physical function was measured by walking capacity (meters walked in 6 minutes). The researchers used administrative records and interviews with staff and patients to estimate the cost-effectiveness of the interventions.
Participant retention in the study was 84%, although only three-quarters of patients receiving the nutritional intervention and less than half (43%) of patients in the physical activity intervention arm adhered to their respective programs. Over 24 months, the incidence rate of pneumonia did not differ between intervention and control groups (32.5 versus 32.6 per 1,000 person years, respectively), but at the end of the study period, there was a significant difference in walking capacity between the intervention and control clusters (mean difference 33.8 meters). The number of falls and fractures in the study arms were similar. The overall costs over 24 months were US$91.00 and US$163.70 per participant for the nutritional supplement and physical activity interventions, respectively. The cost of the physical activity intervention per extra meter walked at 24 months was US$4.84.
What Do These Findings Mean?
The results of this trial suggest that there is little evidence to support the effectiveness of Chile's national nutritional supplementation program in reducing the incidence of pneumonia for 65.0–67.9 year olds. Therefore, given Chile's high burden of infectious and nutrition-related chronic diseases and the associated high health costs, this program should not be considered as a priority preventive public health intervention. However, the provision of locally available physical activity classes to older people could be of clinical benefit, especially in urban settings such as Santiago, although future challenges include increasing the uptake of, and retention to, such programs.

22.  Behavioural Interventions for Urinary Incontinence in Community-Dwelling Seniors 
Executive Summary
In early August 2007, the Medical Advisory Secretariat began work on the Aging in the Community project, an evidence-based review of the literature surrounding healthy aging in the community. The Health System Strategy Division at the Ministry of Health and Long-Term Care subsequently asked the secretariat to provide an evidentiary platform for the ministry’s newly released Aging at Home Strategy.
After a broad literature review and consultation with experts, the secretariat identified 4 key areas that strongly predict an elderly person’s transition from independent community living to a long-term care home. Evidence-based analyses have been prepared for each of these 4 areas: falls and fall-related injuries, urinary incontinence, dementia, and social isolation. For the first area, falls and fall-related injuries, an economic model is described in a separate report.
Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/mas_about.html, to review these titles within the Aging in the Community series.

Objective
To assess the effectiveness of behavioural interventions for the treatment and management of urinary incontinence (UI) in community-dwelling seniors.
Clinical Need: Target Population and Condition
Urinary incontinence defined as “the complaint of any involuntary leakage of urine” was identified as 1 of the key predictors in a senior’s transition from independent community living to admission to a long-term care (LTC) home. Urinary incontinence is a health problem that affects a substantial proportion of Ontario’s community-dwelling seniors (and indirectly affects caregivers), impacting their health, functioning, well-being and quality of life. Based on Canadian studies, prevalence estimates range from 9% to 30% for senior men and nearly double from 19% to 55% for senior women. The direct and indirect costs associated with UI are substantial. It is estimated that the total annual costs in Canada are $1.5 billion (Cdn), and that each year a senior living at home will spend $1,000 to $1,500 on incontinence supplies.
Interventions to treat and manage UI can be classified into broad categories which include lifestyle modification, behavioural techniques, medications, devices (e.g., continence pessaries), surgical interventions and adjunctive measures (e.g., absorbent products).
The focus of this review is behavioural interventions, since they are commonly the first line of treatment considered in seniors given that they are the least invasive options with no reported side effects, do not limit future treatment options, and can be applied in combination with other therapies. In addition, many seniors would not be ideal candidates for other types of interventions involving more risk, such as surgical measures.
Note: It is recognized that the terms “senior” and “elderly” carry a range of meanings for different audiences; this report generally uses the former, but the terms are treated here as essentially interchangeable.
Description of Technology/Therapy
Behavioural interventions can be divided into 2 categories according to the target population: caregiver-dependent techniques and patient-directed techniques. Caregiver-dependent techniques (also known as toileting assistance) are targeted at medically complex, frail individuals living at home with the assistance of a caregiver, who tends to be a family member. These seniors may also have cognitive deficits and/or motor deficits. A health care professional trains the senior’s caregiver to deliver an intervention such as prompted voiding, habit retraining, or timed voiding. The health care professional who trains the caregiver is commonly a nurse or a nurse with advanced training in the management of UI, such as a nurse continence advisor (NCA) or a clinical nurse specialist (CNS).
The second category of behavioural interventions consists of patient-directed techniques targeted towards mobile, motivated seniors. Seniors in this population are cognitively able, free from any major physical deficits, and motivated to regain and/or improve their continence. A nurse or a nurse with advanced training in UI management, such as an NCA or CNS, delivers the patient-directed techniques. These are often provided as multicomponent interventions including a combination of bladder training techniques, pelvic floor muscle training (PFMT), education on bladder control strategies, and self-monitoring. Pelvic floor muscle training, defined as a program of repeated pelvic floor muscle contractions taught and supervised by a health care professional, may be employed as part of a multicomponent intervention or in isolation.
Education is a large component of both caregiver-dependent and patient-directed behavioural interventions, and patient and/or caregiver involvement as well as continued practice strongly affect the success of treatment. Incontinence products, which include a large variety of pads and devices for effective containment of urine, may be used in conjunction with behavioural techniques at any point in the patient’s management.
Evidence-Based Analysis Methods
A comprehensive search strategy was used to identify systematic reviews and randomized controlled trials that examined the effectiveness, safety, and cost-effectiveness of caregiver-dependent and patient-directed behavioural interventions for the treatment of UI in community-dwelling seniors (see Appendix 1).
Research Questions
Are caregiver-dependent behavioural interventions effective in improving UI in medically complex, frail community-dwelling seniors with/without cognitive deficits and/or motor deficits?
Are patient-directed behavioural interventions effective in improving UI in mobile, motivated community-dwelling seniors?
Are behavioural interventions delivered by NCAs or CNSs in a clinic setting effective in improving incontinence outcomes in community-dwelling seniors?
Assessment of Quality of Evidence
The quality of the evidence was assessed as high, moderate, low, or very low according to the GRADE methodology and GRADE Working Group. As per GRADE the following definitions apply:
Summary of Findings
Executive Summary Table 1 summarizes the results of the analysis.
The available evidence was limited by considerable variation in study populations and in the type and severity of UI for studies examining both caregiver-directed and patient-directed interventions. The UI literature frequently is limited to reporting subjective outcome measures such as patient observations and symptoms. The primary outcome of interest, admission to a LTC home, was not reported in the UI literature. The number of eligible studies was low, and there were limited data on long-term follow-up.

Education
Self-monitoring
CI refers to confidence interval; CNS, clinical nurse specialist; NCA, nurse continence advisor; PFMT, pelvic floor muscle training; RCT, randomized controlled trial; WMD, weighted mean difference; UI, urinary incontinence.
Economic Analysis
A budget impact analysis was conducted to forecast costs for caregiver-dependent and patient-directed multicomponent behavioural techniques delivered by NCAs, and PFMT alone delivered by physiotherapists. All costs are reported in 2008 Canadian dollars. Based on epidemiological data, published medical literature and clinical expert opinion, the annual cost of caregiver-dependent behavioural techniques was estimated to be $9.2 M, while the annual costs of patient-directed behavioural techniques delivered by either an NCA or physiotherapist were estimated to be $25.5 M and $36.1 M, respectively. Estimates will vary if the underlying assumptions are changed.
Currently, the province of Ontario absorbs the cost of NCAs (available through the 42 Community Care Access Centres across the province) in the home setting. The 2007 Incontinence Care in the Community Report estimated that the total cost being absorbed by the public system of providing continence care in the home is $19.5 M in Ontario. This cost estimate included resources such as personnel, communication with physicians, record keeping and product costs. Clinic costs were not included in this estimation because currently these come out of the global budget of the respective hospital and very few continence clinics actually exist in the province. The budget impact analysis factored in a cost for the clinic setting, assuming that the public system would absorb the cost with this new model of community care.
Considerations for Ontario Health System
An expert panel on aging in the community met on 3 occasions from January to May 2008, and in part, discussed treatment of UI in seniors in Ontario with a focus on caregiver-dependent and patient-directed behavioural interventions. In particular, the panel discussed how treatment for UI is made available to seniors in Ontario and who provides the service. Some of the major themes arising from the discussions included:
Services/interventions that currently exist in Ontario offering behavioural interventions to treat UI are not consistent. There is a lack of consistency in how seniors access services for treatment of UI, who manages patients and what treatment patients receive.
Help-seeking behaviours are important to consider when designing optimal service delivery methods.
There is considerable social stigma associated with UI and therefore there is a need for public education and an awareness campaign.
The cost of incontinent supplies and the availability of NCAs were highlighted.
Conclusions
There is moderate-quality evidence that the following interventions are effective in improving UI in mobile motivated seniors:
Multicomponent behavioural interventions including a combination of bladder training techniques, PFMT (with or without biofeedback), education on bladder control strategies and self-monitoring techniques.
Pelvic floor muscle training alone.
There is moderate quality evidence that when behavioural interventions are led by NCAs or CNSs in a clinic setting, they are effective in improving UI in seniors.
There is limited low-quality evidence that prompted voiding may be effective in medically complex, frail seniors with motivated caregivers.
There is insufficient evidence for the following interventions in medically complex, frail seniors with motivated caregivers:
habit retraining, and
timed voiding.

23.  Inappropriate benzodiazepine use in older adults and the risk of fracture 
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECTBenzodiazepine use increases the risk of fracture in the elderly.It is controversial which conditions of use are most risky, e.g. use of short- or long-acting benzodiazepines, dose and duration of use.The well-known Beers criteria include statements about inappropriate benzodiazepine use in elderly and the risk of fracture, but their clinical value has never been tested in an outcome study.WHAT THIS STUDY ADDSInappropriate benzodiazepine use according to the Beers criteria is not associated with an increased risk of fracture.Daily dose and duration of use is associated with higher risk of fracture, not the type of benzodiazepine prescribed as the Beers criteria state.
AIMS
The Beers criteria for prescribing in elderly are well known and used for many drug utilization studies. We investigated the clinical value of the Beers criteria for benzodiazepine use, notably the association between inappropriate use and risk of fracture.
METHODS
We performed a nested case–control study within the Rotterdam Study, a population-based cohort study in 7983 elderly. The proportion of ‘inappropriate’ benzodiazepine use according to the Beers criteria was compared between fracture patients and controls. ‘Inappropriate’ use for elderly implies use of some long-acting benzodiazepines and some intermediate/short-acting ones exceeding a suggested maximum daily dose. Also, alternative criteria were applied to compare the risk of fracture. Cases were defined as persons with incident fracture between 1991 and 2002 who were current benzodiazepine users on the fracture date. Controls were matched on fracture date and were also current benzodiazepine users.
RESULTS
The risk of fracture in ‘inappropriate’ benzodiazepine users according to the Beers criteria was not significantly different from ‘appropriate’ users [odds ratio (OR) 1.07, 95% confidence interval (CI) 0.72, 1.60]. However, a significantly higher risk of fracture was found in ‘high dose’ users and a longer duration of use (14–90 days), irrespective of the type of benzodiazepine (OR 3.45, 95% CI 1.38, 8.59).
CONCLUSIONS
These findings suggest that inappropriate benzodiazepine use according to the Beers criteria is not associated with increased risk of fracture. Daily dose and longer duration of use (>14 days) is associated with higher risk of fracture, irrespective of the type of benzodiazepine prescribed.

24.  Hypnotics and the Occurrence of Bone Fractures in Hospitalized Dementia Patients: A Matched Case-Control Study Using a National Inpatient Database 
PLoS ONE  2015;10(6):e0129366.
Background
Preventing falls and bone fractures in hospital care is an important issue in geriatric medicine. Use of hypnotics is a potential risk factor for falls and bone fractures in older patients. However, data are lacking on the association between use of hypnotics and the occurrence of bone fracture.
Methods
We used a national inpatient database including 1,057 hospitals in Japan and included dementia patients aged 50 years or older who were hospitalized during a period of 12 months between April 2012 and March 2013. The primary outcome was the occurrence of bone fracture during hospitalization. Use of hypnotics was compared between patients with and without bone fracture in this matched case-control study.
Results
Of 140,494 patients, 830 patients suffered from in-hospital fracture. A 1:4 matching with age, sex and hospital created 817 cases with fracture and 3,158 matched patients without fracture. With adjustment for the Charlson comorbidity index, emergent admission, activities of daily living, and scores for level walking, a higher occurrence of fractures were seen with short-acting benzodiazepine hypnotics (odds ratio, 1.43; 95% confidence interval, 1.19–1.73; P<0.001), ultrashort-acting non-benzodiazepine hypnotics (1.66; 1.37–2.01; P<0.001), hydroxyzine (1.45; 1.15–1.82, P=0.001), risperidone and perospirone (1.37; 1.08–1.73; P=0.010). Other drug groups were not significantly associated with the occurrence of in-hospital fracture.
Conclusions
Short-acting benzodiazepine hypnotics and ultrashort-acting non-benzodiazepine hypnotics may increase risk of bone fracture in hospitalized dementia patients.

25.  Fracture or Vertebral Deformation? 
Vertebral fractures are the most common osteoporotic fractures, both in Europe and in the USA, affecting 25% of women over 50 years of age. Although often mild and asymptomatic, vertebral fractures have a considerable impact both on the quality of life and on the survival of those affected. In order to allow more precise identification of vertebral fractures, various methods have been proposed over the past 20 years, designed to furnish a more or less quantitative assessment of the spine. These methods can be divided into two groups: visual semi-quantitative (SQ) and morphometric quantitative. The SQ method, being based on the reading of radiographs has the advantage, compared to quantitative morphometry, of allowing differential diagnosis between vertebral deformations and vertebral fractures, and between the various causes, benign or malignant, of vertebral fractures, allowing, in uncertain cases, more complex examinations –CT or MRI – to be undertaken. Since vertebral fractures always manifest themselves as deformations of the vertebral body, but not all vertebral deformations are fractures, an “algorithm-based qualitative assessment” (ABQ) was recently developed in order to identify true vertebral fractures. The ABQ is based on two fundamental points: According to the ABQ, a vertebra is fractured only if there is central vertebral endplate depression.The ABQ introduces the concept of short vertebral height (SVH) to indicate vertebra that show reduced height, but no central depression. Cases of SVH are not fractures, but normal variants, growth-related abnormalities (Scheuermann’s disease), or arthrosic abnormalities.
Thus, all mid-thoracic cuneiform deformities without evident depression of the central endplate are considered SVHs by the ABQ method, but often as fractures by the SQ and morphometric methods. In a recent article, it was shown that SVH is not correlated with low BMD, whereas ABQ-defined deformities are closely associated with BMD in the osteoporotic range.
In clinical practice the assessment of vertebral fractures is commonly based on the radiologist’s reading of radiographs, the first essential step in the differential diagnosis of various causes of vertebral deformity.
Given the possibility, using dual-energy X-ray absorptiometry (DEXA), of obtaining images with good spatial resolution, it was recently suggested that the visual examination of these images might be used for the identification of vertebral fractures, a method called “vertebral fracture assessment (VFA)”. One advantage of this diagnostic approach is that it can be performed using low doses of radiation and be associated with the measurement of bone mineral density, thereby allowing, contemporaneously, both a qualitative and a quantitative evaluation of the spine, useful for the correct identification of vertebral fractures. According to the findings of recent studies, VFA shows a good level of agreement (96.3%) with semi-quantitative assessment of radiographs in the classification of vertebrae as normal or deformed. Furthermore, the VFA method has been shown to have excellent negative predictive value (98.0%) in distinguishing subjects with normal vertebrae from those with definite or possible vertebral deformities.
In 2005, the ISCD proposed the following diagnostic pathway for the identification of osteoporotic vertebral fractures in the presence of fracture risk factors: using the VFA method, perform an initial visual assessment of the spine on DEXA images;classify patients as normal if all the vertebrae are clearly visualised and found to be normal;classify patients as fractured in the presence of a moderate or severe fracture, identified using Genant’s SQ method;perform a radiographic examination if, on VFA, not all the vertebrae are visualised, orif one or more mild vertebral deformities are identified;on the radiograph, distinguish fractures from mild, non-fracture deformities;determine the type and severity of the fracture according to the SQ method;use morphometry to confirm the presence and severity of the fracture;over time, monitor the patient at risk of fragility fracture, using VFA as well as DEXA densitometry.
In conclusion, by associating VFA with definition – not only quantitative, but also qualitative – of fractures, it will be possible to identify a greater number of true mild, asymptomatic fractures, which constitute the evidence on which to base a drug treatment geared at preventing the occurrence of new fractures, which would be more severe and disabling. To achieve this, there is nevertheless a need for close collaboration between the clinician who requests the examination and the radiologist whose task it is to provide a report, both qualitative and morphometric, of the image of the spine.
