Chronic diseases represent a major challenge for health care and social services. A number of people with chronic diseases require more services due to characteristics that increase their vulnerability. Given the burden of increasingly vulnerable patients on primary care, a pragmatic intervention in four Family Medicine Groups (primary care practices in Quebec, Canada) has been proposed for individuals with chronic diseases (diabetes, cardiovascular diseases, respiratory diseases, musculoskeletal diseases and/or chronic pain) who are frequent users of hospital services. The intervention combines case management by a nurse with group support meetings encouraging self-management based on the Stanford Chronic Disease Self-Management Program. The goals of this study are to: (1) analyze the implementation of the intervention in the participating practices in order to determine how the various contexts have influenced the implementation and the observed effects; (2) evaluate the proximal (self-efficacy, self-management, health habits, activation and psychological distress) and intermediate (empowerment, quality of life and health care use) effects of the intervention on patients; (3) conduct an economic analysis of the efficiency and cost-effectiveness of the intervention.
The analysis of the implementation will be conducted using realistic evaluation and participatory approaches within four categories of stakeholders (Family Medicine Group and health centre management, Family Medicine Group practitioners, patients and their families, health centre or community partners). The data will be obtained through individual and group interviews, project documentation reviews and by documenting the intervention. Evaluation of the effects on patients will be based on a pragmatic randomized before-after experimental design with a delayed intervention control group (six months). Economic analysis will include cost-effectiveness and cost-benefit analysis.
The integration of a case management intervention delivered by nurses and self-management group support into primary care practices has the potential to positively impact patient empowerment and quality of life and hopefully reduce the burden on health care. Decision-makers, managers and health care professionals will be aware of the factors to consider in promoting the implementation of this intervention into other primary care practices in the region and elsewhere.

Obstructive sleep apnea (OSA) is becoming increasingly prevalent in North America and has been described in association with specific chronic diseases, particularly cardiovascular diseases. In primary care, where the prevalence of co-occurring chronic conditions is very high, the potential association with OSA is unknown. The purpose of this study was to explore the association between OSA and 1) the presence and severity of multimorbidity (multiple co-occurring chronic conditions), and 2) subcategories of multimorbidity.
A cluster sampling technique was used to recruit 120 patients presenting with OSA of various severities from the records of a sleep laboratory in 2008. Severity of OSA was based on the results of the polysomnography. Patients invited to participate received a mail questionnaire including questions on sociodemographic characteristics and the Disease Burden Morbidity Assessment (DBMA). They also consented to give access to their medical records. The DBMA was used to provide an overall multimorbidity score and sub-score of diseases affecting various systems.
Bivariate analysis did not demonstrate an association between OSA and multimorbidity (r = 0.117; p = 0.205). However, severe OSA was associated with multimorbidity (adjusted odds ratio = 7.33 [1.67-32.23], p = 0.05). OSA was moderately correlated with vascular (r = 0.26, p = 0.01) and metabolic syndrome (r = 0.26, p = 0.01) multimorbidity sub-scores.
This study showed that severe OSA is associated with severe multimorbidity and sub-scores of multimorbidity. These results do not allow any causal inference. More research is required to confirm these associations. However, primary care providers should be aware of these potential associations and investigate OSA when deemed appropriate.

Multimorbidity is now acknowledged as a research priority in primary care. The identification of risk factors and people most at risk is an important step in guiding prevention and intervention strategies. The aim of this study was to examine the relationship between literacy and multimorbidity while controlling for potential confounders.
Participants were adult patients attending the family medicine clinic of a regional health centre in Saguenay (Quebec), Canada. Literacy was measured with the Newest Vital Sign (NVS). Multimorbidity was measured with the Disease Burden Morbidity Assessment (DBMA) by self-report. Information on potential confounders (age, sex, education and family income) was also collected. The association between literacy (independent variable) and multimorbidity was examined in bivariate and multivariate analyses. Two operational definitions of multimorbidity were used successively as the dependent variable; confounding variables were introduced into the model as potential predictors.
One hundred three patients (36 men) 19–83 years old were recruited; 41.8% had completed 12 years of school or less. Forty-seven percent of patients provided fewer than four correct answers on the NVS (possible low literacy) whereas 53% had four correct responses or more. Literacy and multimorbidity were associated in bivariate analyses (p < 0.01) but not in multivariate analyses, including age and family income.
This study suggests that there is no relationship between literacy and multimorbidity when controlling for age and family income.
The Disease Burden Morbidity Assessment (DBMA) is a self-report questionnaire used to estimate the disease burden experienced by patients. The aim of this study was to test and to measure the properties of the French translation of the DBMA (DBMA-Fv).
The original version of the DBMA was translated into French (Canadian) and first assessed during cognitive interviews. In the validation study, patients recruited during consecutive consultation periods completed the DBMA-Fv questionnaire while they were in the waiting room of a primary care setting (T1). Participants completed the same questionnaire mailed to their home two weeks later (T2). Concomitant validity of the DBMA-Fv was assessed using the Cumulative Illness Rating Scale (CIRS). Patient medical records were reviewed to verify chronic diseases and past medical history.
Ninety-seven patients were recruited and 85 (88%) returned the mailed questionnaires; 5 (5.9%) were incomplete. DBMA-Fv scores of the 80 participants with a complete questionnaire at T2 ranged from 0 to 30 (median 5.5, mean 7.7, SD = 7.0). Test-retest reliability of the DBMA-Fv was high (ICC: 0.86, 95% CI: 0.79-0.92). The DBMA-Fv and the CIRS correlated moderately at T1 (r = 0.46, 95% CI: 0.26 - 0.62, p < 0.01) and T2 (r = 0.56, 95% CI: 0.38 - 0.70, p < 0.01). The mean (SD) sensitivity of patient reports of a condition in relation to chart review at T2 was 73.9 (8.4) (range 62.5% to 90%). The overall mean (SD) specificity was 92.2 (6.7) (range 77.6% to 98.6%).
The DBMA-Fv's properties are similar to its English counterpart as to its median sensitivity and specificity compared to chart reviews. It correlated moderately with an established index of multimorbidity. A high percentage of patients were able to complete the test correctly as a mail questionnaire and it showed high test-retest reliability.
Clinical guidelines have been the subject of much criticism in primary care literature partly due to potential conflicts in their implementation among patients with multiple chronic conditions. We assessed the relevance of selected Canadian clinical guidelines on chronic diseases for patients with comorbidity and examined their quality.
We selected 16 chronic medical conditions according to their frequency of occurrence, complexity of treatment, and pertinence to primary care. Recent Canadian clinical guidelines (2004 - 2009) on these conditions, published in English or French, were retrieved. We assessed guideline relevance to the care of patients with comorbidity with a tool developed by Boyd and colleagues. Quality was assessed using the Appraisal of Guidelines Research and Evaluation (AGREE) instrument.
Regarding relevance, 56.2% of guidelines addressed treatment for patients with multiple chronic conditions and 18.8% addressed the issue for older patients. Fifteen guidelines (93.8%) included specific recommendations for patients with one concurrent condition; only three guidelines (18.8%) addressed specific recommendations for patients with two comorbid conditions and one for more than two concurrent comorbid conditions. Quality of the evaluated guidelines was good to very good in four out of the six domains measured using the AGREE instrument. The domains with lower mean scores were Stakeholder Involvement and Applicability.
The quality of the Canadian guidelines examined is generally good, yet their relevance for patients with two or more chronic conditions is very limited and there is room for improvement in this respect.
Patient enablement can be defined as the extent to which a patient is capable of understanding and coping with his or her health issues. This concept is linked to a number of health outcomes such as self-management of chronic diseases and quality of life. The Patient Enablement Instrument (PEI) was designed to measure this concept after a medical consultation. The instrument, in its original form and its translations into several languages, has proven to be reliable and valid. The purpose of this study was to evaluate the reliability of the French version of the PEI (PEI-Fv) in a family practice setting.
One hundred and ten participants were recruited in a family medicine clinic in the Saguenay region of Quebec (Canada). The PEI-Fv was completed twice, immediately after consultation with a physician (T1) and 2 weeks after the consultation (T2). The internal consistency of the tool was assessed with Cronbach's α and test-retest reliability by intraclass correlation coefficient.
The mean score for the PEI-Fv was 5.06 ± 3.97 (95% confidence interval [CI]: 4.30-5.81) at T1 and 4.63 ± 3.90 (95% CI: 3.82-5.44) at T2. Cronbach's α was high at T1 (α1 = 0.93; 95% CI: 0.91-0.95) and T2 (α2 = 0.93; 95% CI: 0.91-0.95). The intraclass correlation coefficient was 0.62 (95% CI: 0.48-0.74), indicating a moderate test-retest reliability.
The internal consistency of the PEI-Fv is excellent. Test-retest reliability was moderate to good. Test-retest reliability should be examined in further studies at a less than 2-week interval to reduce maturation bias. This instrument can be used to measure enablement after consultation in a French-speaking family practice setting.
In October 2006, federal funding was announced for the development of a national strategy to fight cardiovascular disease (CVD) in Canada. The comprehensive, independent, stakeholder-driven Canadian Heart Health Strategy and Action Plan (CHHS-AP) was delivered to the Minister of Health on February 24, 2009.
The mandate of CHHS-AP Theme Working Group (TWG) 6 was to identify the optimal chronic disease management model that incorporated timely access to rehabilitation services and end-of-life planning and care. The purpose of the present paper was to provide an overview of worldwide approaches to CVD and cardiac rehabilitation (CR) strategies and recommendations for CR care in Canada, within the context of the well-known Chronic Care Model (CCM). A separate paper will address end-of-life issues in CVD.
TWG 6 was composed of content representatives, primary care representatives and patients. Input in the area of Aboriginal and indigenous cardiovascular health was obtained through individual expert consultation. Information germane to the present paper was gathered from international literature and best practice guidelines. The CCM principles were discussed and agreed on by all. Prioritization of recommendations and overall messaging was discussed and decided on within the entire TWG. The full TWG report was presented to the CHHS-AP Steering Committee and was used to inform the recommendations of the CHHS-AP.
Specific actionable recommendations for CR are made in accordance with the key principles of the CCM.
The present CR blueprint, as part of the CHHS-AP, will be a first step toward reducing the health care burden of CVD in Canada.

The inverse care law persists: people living in poverty have the greatest needs and face considerable challenges in getting the care they need. Evidence reveals that GPs encounter difficulties in delivering care to poor patients, while many of those patients feel stigmatized by healthcare professionals. Patients living in poverty report negative healthcare experiences and unmet healthcare needs. Indeed, there is a growing recognition in primary care research of the importance of addressing the capabilities and social conditions of the poor when delivering care. Few studies have looked at the factors contributing to effective and "socially responsive" care for people living in poverty.
Our study adopts a qualitative ethnographic approach in four healthcare organizations in deprived areas of metropolitan Montreal (Québec, Canada), using patient shadowing techniques and interviews. Data will be collected through fieldwork observations and informal interviews with patients before and after consultations. We will observe medical consultations, care organization activities, and waiting areas and reception of patients. We will conduct a total of 36 individual interviews with 12 GPs and 24 patients. The interviews will be audio-recorded and transcribed for purposes of analysis. The analysis consists of debriefing sessions, coding and interpretive analysis.
This study aims to investigate how positive healthcare interactions between physicians and patients can improve the management of chronic conditions. We hypothesize that factors related to care organization, to healthcare professionals' experience and to patients may enhance the quality of healthcare interactions, which may have positive impacts for preventing and managing chronic conditions. Our study will provide a unique set of data grounded in the perspectives of healthcare professionals and of patients living in poverty.
Among the strategies used to reform primary care, the participation of nurses in primary care practices appears to offer a promising avenue to better meet the needs of vulnerable patients. The present study explores the perceptions and expectations of patients with multimorbidity regarding nurses' presence in primary care practices.
18 primary (health) care patients with multimorbidity participated in semi-directed interviews, in order to explore their perceptions and expectations in regard to the involvement of nurses in primary care practices. Interviews were audio-recorded and transcribed. After reviewing the transcripts, the principal investigator and research assistants performed thematic analysis independently and reached consensus on the retained themes.
Patients with multimorbidity were open to the participation of nurses in primary care practices. They expected greater accessibility, for both themselves and for new patients. However, the issue of shared roles between nurses and doctors was a source of concern. Many patients held the traditional view of the nurse's role as an assistant to the doctor in his or her various duties. In general, participants said they were confident about nurses' competency but expressed concern about nurses performing certain acts that their doctor used to, notwithstanding a close collaboration between the two professionals.
Patients with multimorbidity are open to the involvement of nurses in primary care practices. However, they expect this participation to be established using clear definitions of professional roles and fields of practice.
Massive efforts in Canada have been made to renew primary healthcare. However, although early evaluations of initiatives and research on certain aspects of the reform are promising, none have examined the link between patient assessments of care and health outcomes or the impacts at a population level. The goal of this project is to examine the effect of patient-centred and effective primary healthcare on the evolution of chronic illness burden and health functioning in a population, and in particularly vulnerable groups: the multi-morbid and the poor.
A randomly selected cohort of 2000 adults aged 25 to 75 years will be recruited within the geographic boundaries of four local healthcare networks in Quebec. At recruitment, cohort members will report on socio-demographic information, functional health and healthcare use. Two weeks, 12 months and 24 months after recruitment, cohort participants will complete a self-administered questionnaire on current health and health behaviours in order to evaluate primary healthcare received in the previous year.
The dependent variables are calculated as change over time of functional health status, chronic illness burden, and health behaviours. Dimensions of patient-centred care and clinical processes are measured using sub-scales of validated instruments. We will use Poisson regression modelling to estimate the incidence rate of chronic illness burden scores and structural equation modelling to explore relationships between variables and to examine the impact of dimensions of patient-centred care and effective primary healthcare.
Results will provide valuable information for primary healthcare clinicians on the course of chronic illness over time and the impact on health outcomes of accessible, patient-centred and effective care. A demonstration of impact will contribute to the promotion of continuous quality improvement activities at a clinical level. While considerable advances have been made in the management of specific chronic illnesses, this will make a unique contribution to effective care for persons with multiple morbidities. Furthermore, the cohort and data architecture will serve as a research platform for future projects.
We introduce a primary care practice model for caring for patients with multimorbidity. Primary care for these patients requires flexibility and ongoing coordination, and it often must be tailored to individual circumstances. Such complex and flexible care could be accomplished within communities of practice, whose participants are willing to learn from their shared practice, further each other’s goals, share their stories of success and failure, and promote the continued evolution of collective learning. Primary care in these communities would be conceived as a complex adaptive process in which the participants use an iterative approach to care improvement that integrates what they learn and do collectively over time. Clinicians in these communities would define common goals, cocreate care plans, and engage in reflective case-based learning. As community members manage their knowledge, gain insights, and develop new care strategies, they can improve care for patients with multiple conditions. Using a mix of methods, future research should explore the conditions that are necessary for collective learning within communities of clinicians who care for patients with multimorbidity and who develop new knowledge in practice. By understanding these conditions, we can foster the development of collective learning and improve primary care for these patients.

Time to focus on the needs of this vulnerable and growing population
Published prevalence studies on multimorbidity present diverse data collection methods, sources of data, targeted age groups, diagnoses considered and study populations, making the comparability of prevalence estimates questionable. The objective of this study was to compare prevalence estimates of multimorbidity derived from two sources and to examine the impact of the number of diagnoses considered in the measurement of multimorbidity.
Prevalence of multimorbidity was estimated in adults over 25 years of age from two separate Canadian studies: a 2005 survey of 26,000 respondents randomly selected from the general population and a 2003 study of 980 patients from 21 family practices. We estimated the prevalence of multimorbidity based on the co-occurrence of ≥ 2 and ≥ 3 diseases of the seven diseases listed in the general population survey. For primary care patients, we also estimated multimorbidity prevalence using an open list of chronic diseases.
Prevalence estimates were considerably higher for each age group in the primary care sample than in the general population. For primary care patients, the number of chronic diseases considered for estimates resulted in large differences, especially in younger age groups. The prevalence of multimorbidity increased with age in both study populations.
The prevalence of multimorbidity was substantially lower when estimated in a general population than in a family practice-based sample and was higher when the number of conditions considered increased.
The quality of the physician-patient therapeutic relationship is a key factor in the effectiveness of care. Unfortunately, physicians and people living in poverty inhabit very different social milieux, and this great social distance hinders the development of a therapeutic alliance. Social competence is a process based on knowledge, skills and attitudes that support effective interaction between the physician and patient despite the intervening social distance. It enables physicians to better understand their patients' living conditions and to adapt care to patients' needs and abilities.
This qualitative research is based on a comprehensive design using in-depth semi-structured interviews with 25 general practitioners working with low-income patients in Montreal's metropolitan area (Québec, Canada). Physicians will be recruited based on two criteria: they provide care to low-income patients with at least one chronic illness, and are identified by their peers as having expertise in providing care to a poor population. For this recruitment, we will draw upon contacts we have made in another research study (Loignon et al., 2009) involving clinics located in poor neighbourhoods. That study will include in-clinic observations and interviews with physicians, both of which will help us identify physicians who have developed skills for treating low-income patients. We will also use the snowball sampling technique, asking participants to refer us to other physicians who meet our inclusion criteria. The semi-structured interviews, of 60 to 90 minutes each, will be recorded and transcribed. Our techniques for ensuring internal validity will include data analysis of transcribed interviews, indexation and reduction of data with software qualitative analysis, and development and validation of interpretations.
This research project will allow us to identify the dimensions of the social competence process that helps physicians establish therapeutic relationships with low-income patients living with chronic illness. This study will also offer concrete recommendations for improving health interventions among low-income patients and for helping them to better manage their chronic illnesses. Ultimately, our aim is to strengthen the capacity of the health care system and of professionals to provide care that is adapted to the social conditions of people living in poverty.
Reports on the relationship between comorbidity and glycemia control in diabetic patients are conflicting and the method of measuring comorbidity varies widely among studies. The aim of the present study was to evaluate the relationship between diabetes control and comorbidity, taking into account all comorbidities and their severity, in a primary care setting. We performed a retrospective descriptive study based on chart review of 96 randomly selected type 2 diabetic patients. Comorbidity was measured with the cumulative illness rating scale (CIRS), an exhaustive comorbidity index. Diabetes was considered as controlled if the mean value of two measurements of glycosylated hemoglobin A (HbA1c) was less than 7%. Taking diabetes control as the dependent variable, its relationship with the CIRS score, age, sex, diabetes duration, and diabetes-related complications was explored. Diabetes control was not significantly related with the CIRS score, age, sex or diabetes severity. Diabetes duration was the only variable significantly related to diabetes control. Our study suggests that comorbidity measured with the CIRS in patients with type 2 diabetes is not a factor that prevents the achievement of a good glycemia control.

Abundant literature supports the beneficial effects of physical activity for improving health of people with chronic diseases. The relationship between multimorbidity and physical activity levels, however, has been little evaluated. The purpose of the current exploratory study was to examine the relationship between a) multimorbidity and physical activity levels, and b) long-term limitations on activity, self-rated general health, psychological distress, and physical activity levels for each sex in adults, after age, education, income, and employment factors were controlled for.
Data from the Quebec Health Survey 1998 were used. The sample included 16,782 adults 18–69 yr of age. Independent variables were multimorbidity, long-term limitations on activity, self-rated general health, and psychological distress. The dependent variable was physical activity levels. Links between the independent and dependent variables were assessed separately for men and women with multinomial regressions while accounting for the survey sampling design and household clustering.
About 46% of the participants were men. Multimorbidity was not associated with physical activity levels for either men or women. Men and women with long-term limitations on activity and with poor-to-average self-rated general health were less likely to be physically active. No relationship between psychological distress and physical activity was found for men. Women with high levels of psychological distress were less likely to be physically active.
Multimorbidity was not associated with physical activity levels in either sex, when age, education, income, and employment factors were controlled for. Long-term limitations on activity and poor-to-average self-rated general health seem related to a reduction in physical activity levels for both sexes, whereas psychological distress was associated with a reduction in physical activity levels only among women. Longitudinal studies using a comorbidity or multimorbidity index to account for severity of the chronic diseases are needed to replicate the results of this exploratory study.
To provide a summary of evidence on the effectiveness of interventions to promote physical activity among patients affected by at least 1 chronic disease. The interventions studied were each targeted at a single risk factor.
MEDLINE, CINAHL, and EMBASE were searched from 1966 to 2006 using 2 sets of search terms. First we searched using physical activity or physical fitness or exercise and health care or primary care or primary health care or family practice or medical office or physician’s office and health promotion or health education or counselling. Then we used physical activity or exercise and diabetes or hyperlipidemia or hypertension or obesity or cardiovascular disease or pulmonary disease or risk factor or comorbidity and health promotion or health education or counselling or prescription.
We chose randomized controlled trials or trials with a controlled quasi-experimental design that evaluated single risk factor interventions to promote physical activity among adult patients in primary care settings who were affected by at least 1 chronic disease, that reported participation in physical activity as a primary outcome, and that were published in English or French.
Of the 4858 articles found, 62 were assessed, and 3 were selected. Two studies concluded that the interventions evaluated had no effect on level of physical activity. The other reported a positive short-term effect with use of an intensive intervention that was based on the theory of planned behaviour and integrated nurses into the general practitioner counseling process.
There is insufficient evidence to assess the effectiveness of single risk factor interventions to promote physical activity among patients affected by at least 1 chronic disease in primary care settings. Of 3 studies, only 1 reported a short-term positive effect.

Proportion de patients ayant des conditions musculo-squelettiques chroniques et, dans ce sous-échantillon, le nombre moyen de comorbidités et la proportion de patients atteints de maladies chroniques (hypertension, maladies cardio-vasculaires, maladies rénales et ulcères d’estomac ou reflux) pouvant se détériorer avec la prise d’AINS.
La banque de données comprenait 980 patients dont l’âge moyen était 56 ans. La prévalence des conditions musculo-squelettiques chroniques s’élevait à 58%pour l’ensemble de l’échantillon. Parmi les patients atteints de ces conditions, le nombre de comorbidités variait de 0 à 11 pour une moyenne de 4. Environ 49% des patients avaient de l’hypertension, 31% des maladies cardiaques, 31% des troubles urinaires ou maladies du rein et 17% des ulcères d’estomac ou du reflux. Finalement, 70% des patients avec des conditions musculo-squelettiques chroniques présentaient au moins une comorbidité parmi les 4 énumérées.
Plus de la moitié des patients qui consultent en première ligne ont des conditions musculo-squelettiques chroniques. Le nombre moyen de comorbidités parmi ces patients est élevé et plusieurs présentent des comorbidités qui peuvent se détériorer avec l’usage d’AINS. Le médecin de famille doit donc demeurer vigilant avec l’utilisation des AINS dans cette clientèle.
Nearly 50% of Canadians are overweight and their number is increasing rapidly. The majority of obese subjects are treated by primary care physicians (PCPs) who often feel uncomfortable with the management of obesity. The current research proposal is aimed at the development and implementation of an innovative, integrated, interdisciplinary obesity care management system involving both primary and secondary care professionals.
We will use both action and evaluative research in order to achieve the following specific objectives. The first one is to develop and implement a preceptorship-based continuing medical education (CME) program complemented by a web site for physicians and nurses working in Family Medicine Groups (FMGs). This CME will be based on needs assessment and will be validated by one FMG using questionnaires and semi structured interviews. Also, references and teaching tools will be available for participants on the web site. Our second objective is to establish a collaborative intra and inter-regional interdisciplinary network to enable on-going expertise update and networking for FMG teams. This tool consists of a discussion forum and monthly virtual meetings of all participants. Our third objective is to evaluate the implementation of our program for its ability to train 8 FMGs per year, the access and utilization of electronic tools and the participants' satisfaction. This will be measured with questionnaires, web logging tools and group interviews. Our fourth objective is to determine the impact for the participants regarding knowledge and expertise, attitudes and perceptions, self-efficacy for the management of obesity, and changes in FMG organization for obesity management. Questionnaires and interviews will be used for this purpose. Our fifth objective is to deliver transferable knowledge for health professionals and decision-makers. Strategies and pitfalls of setting up this program will also be identified.
This project is relevant to health system's decision-makers who are confronted with an important increase in the prevalence of obesity. It is therefore critical to develop strategies allowing the management of obesity in the 1st line setting. Results of this research project could therefore influence health care organization in the field of obesity but also eventually for other chronic diseases.
The presence of multiple chronic conditions is associated with lower health related quality of life (HRQOL). Disease severity also influences HRQOL. To analyse the effects of all possible combinations of single diseases along with their severity on HRQOL seems cumbersome. Grouping diseases and their severity in specific organ domains may facilitate the study of the complex relationship between multiple chronic conditions and HRQOL. The goal of this study was to analyse impaired organ domains that affect the most HRQOL of patients with multiple chronic conditions in primary care and their possible interactions.
We analysed data from 238 patients recruited from the clientele of 21 family physicians. We classified all chronic conditions along with the measure of their severity into the 14 organ domains of the Cumulative Illness Rating Scale (CIRS). Patients also completed the 36-item Medical Outcomes Study questionnaire (SF-36). One-way analyses of variance were performed to study the relationship between the severity score for each CIRS domain and both physical component summary (PCS) and mental component summary (MCS) of HRQOL. Two-way analyses of variance were conducted to investigate the significance of possible organ domains interactions. Variables involved in significant bivariate relationships or interactions were candidates for inclusion in a multivariate model. Five additional variables were included in the multivariate model because of their possible confounding effect: perceived social support, age, education, perceived economic status and residual CIRS.
Significant differences in the PCS (p < 0.01) were found in 12 of the 14 CIRS organ domains. A significant difference in MCS was found only in the Psychiatric domain. In the multivariate analysis for the PCS, the CIRS domains Musculoskeletal, Neurological, and Psychiatric, had an independent direct impact on PCS while the Upper gastrointestinal, Vascular, Cardiac and Respiratory domains were involved in interactions. A multivariate model was not necessary for the mental component.
Vascular, Upper gastrointestinal and Musculoskeletal systems have strong negative effects on HRQOL. Among combinations of systems, the respiratory and cardiac combination is of particular concern because of a synergistic negative effect. This study paves the way for a future study with a bigger sample that could yield a model of wider generalizability.
The quality of the relationship with the spouse/partner appears crucial among patients with multiple chronic conditions where illness management is complex and multifaceted. This study draws on data from the Quebec Health Survey (QHS) to examine, among patients with one or more chronic conditions, the relation between marital status, the perceived conflict with the spouse/partner, and what the patients do to manage their illness as well as how they perceive their health.
Data from the QHS 1998 were used. The sample included 7547 coupled adults who had one or more chronic health problems lasting more than 6 months. Independent variables included marital status, perceived conflict with the spouse/partner, and the number of chronic conditions. Illness management was defined broadly as a measure of the patient's efforts at self-care and an illness status indicator, including visits to the generalist and the specialist, the use of telephone health line in the last 12 months, self-rated general health, mental health, and a measure of psychological distress. Linkages between the independent variables and illness management were assessed for males and females separately with logistic regressions, while accounting for the survey sampling design and household clustering.
Female patients who did not live with their partner and had never been married were more likely to report a negative perception of their general health and a higher psychological distress than those who were married. Perceived conflict with the partner was linked to a negative perception of mental health and a higher psychological distress among both men and women. Compared to patients with only one chronic condition, males who reported more than one chronic condition were more likely to have consulted a generalist prior to the survey and used the telephone health line, whereas females were more likely to have consulted a specialist. Both males and females with more than one chronic condition were more likely to have a negative perception of their general health and mental health.
The study provides a useful preliminary measure of the importance of living arrangements and the quality of the couple relationship in chronic illness management broadly conceived as a measure of the patient's efforts at self-care and an illness status indicator. Results of this study prod us to examine more closely, within longitudinal designs, the influence of living arrangements and the presence of conflict in the couple on chronic illness management as well as the modifying effect of gender on these associations.
Measures of multimorbidity are often applied to source data, populations or outcomes outside the scope of their original developmental work. As the development of a multimorbidity measure is influenced by the population and outcome used, these influences should be taken into account when selecting a multimorbidity index. The aim of this study was to compare the strength of the association of health-related quality of life (HRQOL) with three multimorbidity indices: the Cumulative Illness Rating Scale (CIRS), the Charlson index (Charlson) and the Functional Comorbidity Index (FCI). The first two indices were not developed in light of HRQOL.
We used data on chronic diseases and on the SF-36 questionnaire assessing HRQOL of 238 adult primary care patients who participated in a previous study. We extracted all the diagnoses for every patient from chart review to score the CIRS, the FCI and the Charlson. Data for potential confounders (age, sex, self-perceived economic status and self-perceived social support) were also collected. We calculated the Pearson correlation coefficients (r) of the SF-36 scores with the three measures of multimorbidity, as well as the coefficient of determination, R2, while controlling for confounders.
The r values for the CIRS (range: -0.55 to -0.18) were always higher than those for the FCI (-0.47 to -0.10) and Charlson (-0.31 to -0.04) indices. The CIRS explained the highest percent of variation in all scores of the SF-36, except for the Mental Component Summary Score where the variation was not significant. Variations explained by the FCI were significant in all scores of SF-36 measuring physical health and in two scales evaluating mental health. Variations explained by the Charlson were significant in only three scores measuring physical health.
The CIRS is a better choice as a measure of multimorbidity than the FCI and the Charlson when HRQOL is the outcome of interest. However, the FCI may provide a good option to evaluate the physical aspect of HRQOL for the ease in its administration and scoring. The Charlson index may not be recommended as a measure of multimorbidity in studies related to either physical or mental aspects of HRQOL.
