1.  Cross-cultural and factorial validity of PTSD check list—military version (PCL-M) in Sinhalese language 
European Journal of Psychotraumatology  2013;4:10.3402/ejpt.v4i0.19707.
Background
There are currently no validated instruments to assess the burden of combat-related Posttraumatic Stress Disorder (PTSD) in Sinhalese—the main spoken language in Sri Lanka.
Objective
The purpose of this research was to establish the cross-cultural and structural validity of the PTSD Check List—Military Version (PCL-M) translated into Sinhalese.
Methods
Expert committee consensus generation as well as translation–back translation approaches were used to establish the semantic, conceptual, and content equivalence of the Sinhalese and English versions of the PCL-M. Four translations of each item were made. In the absence of any “gold standard” psychometric instrument in Sinhalese to establish the criterion validity for the PCL-M (SIN), the study utilized more informal checks for assessment of validity and Sri Lankan cutoffs for caseness for PTSD to establish the psychometric strength of the translated instrument along with standard reliability analysis.
Confirmatory factor analysis was performed on PCL-M scoring of a random sample of 1,586 soldiers to examine construct validity.
Results
Thirteen of the 17 items were selected by popular vote, and the remaining 4 through discussion and consensus. Reliability measured by Cronbach's-α was 0.944 for the total scale and 0.812, 0.869, and 0.895 for the three DSM-IV sub-scales (re-experiencing, avoidance/numbing, and hyperarousal), respectively. The desired cutoff point for the translated instrument was determined to be 44.
The five-factor model by Elhai et al. and the four-factor model by King et al. fitted best, demonstrating good fit to all three fit indices, while the four-factor model and the DSM-IV three-factor model by Simms et al. only had acceptable levels of fit for root mean squared error of approximation. χ2 difference test comparing the two better-fitting models suggests that the five-factor model by Elhai et al. has the better fit.
Conclusion
The PCL-M (SIN) version is suitable for use in the study of PTSD in the Sri Lankan military forces, as judged by cross-cultural and construct validity as well as reliability.

2.  Managing mood disorders in patients attending pulmonary rehabilitation clinics 
Background
There is good evidence for the positive benefits of pulmonary rehabilitation (PR) in the prevention of hospital admissions, lower mortality, and improved health-related quality of life. There is also increasing evidence about the impact of PR on mental health and, in particular, mood disorders. We aimed to identify how depression in chronic obstructive pulmonary disease (COPD) patients in Victoria, Australia, is being managed in PR, to identify the prevalence of depressive symptoms among COPD patients who attend PR, and to determine whether patients with depressive symptoms or anxiety symptoms dropped out of PR early.
Method
Of 61 PR clinics, 44 were invited and 22 agreed to participate. Telephone interviews were conducted to see how depression and anxiety in COPD patients were being recognized and managed in these clinics. A total of 294 questionnaires were distributed to patients by clinic coordinators to determine the prevalence of anxiety/depression, as measured by the Hospital Anxiety and Depression Scale. Coordinators were contacted to provide information on whether respondents dropped out of rehabilitation early or continued with their treatment at 2–4 months post program.
Results
Seven clinics were not aware of local guidelines on assessment/treatment/management of mood. Four clinics did not use any screening tools or other aids in the recognition and management of depression and/or anxiety. Overall, eight clinics participating in this study requested advice on suitable screening tools. The patient survey indicated that the mean depression score on the Hospital Anxiety and Depression Scale was 5.0 (standard deviation 3.0, range 1–13). The mean anxiety score was 5.5 (standard deviation 3.4, range 0–18). There was no evidence of a link between failure to complete rehabilitation and depression or anxiety scores, as only three of 105 patients failed to complete their rehabilitation.
Discussion: Awareness of management guidelines for depression and anxiety in COPD patients was variable across the clinics recruited into our study. We found no link between compliance with rehabilitation and depression, but our sample had limitations.
Conclusion
Future research needs to investigate how best to encourage more use of available guidelines regarding integrating psychological and psychosocial support to supplement the exercise and education that are currently offered routinely by all PR clinics studied in Victoria, Australia.

3.  Effects of case management in community aged care on client and carer outcomes: a systematic review of randomized trials and comparative observational studies 
Background
Case management has been applied in community aged care to meet frail older people’s holistic needs and promote cost-effectiveness. This systematic review aims to evaluate the effects of case management in community aged care on client and carer outcomes.
Methods
We searched Web of Science, Scopus, Medline, CINAHL (EBSCO) and PsycINFO (CSA) from inception to 2011 July. Inclusion criteria were: no restriction on date, English language, community-dwelling older people and/or carers, case management in community aged care, published in refereed journals, randomized control trials (RCTs) or comparative observational studies, examining client or carer outcomes. Quality of studies was assessed by using such indicators as quality control, randomization, comparability, follow-up rate, dropout, blinding assessors, and intention-to-treat analysis. Two reviewers independently screened potentially relevant studies, extracted information and assessed study quality. A narrative summary of findings were presented.
Results
Ten RCTs and five comparative observational studies were identified. One RCT was rated high quality. Client outcomes included mortality (7 studies), physical or cognitive functioning (6 studies), medical conditions (2 studies), behavioral problems (2 studies) , unmet service needs (3 studies), psychological health or well-being (7 studies) , and satisfaction with care (4 studies), while carer outcomes included stress or burden (6 studies), satisfaction with care (2 studies), psychological health or well-being (5 studies), and social consequences (such as social support and relationships with clients) (2 studies). Five of the seven studies reported that case management in community aged care interventions significantly improved psychological health or well-being in the intervention group, while all the three studies consistently reported fewer unmet service needs among the intervention participants. In contrast, available studies reported mixed results regarding client physical or cognitive functioning and carer stress or burden. There was also limited evidence indicating significant effects of the interventions on the other client and carer outcomes as described above.
Conclusions
Available evidence showed that case management in community aged care can improve client psychological health or well-being and unmet service needs. Future studies should investigate what specific components of case management are crucial in improving clients and their carers’ outcomes.

4.  Signs of progress in the Australian post-2000 COPD experience, but some old problems remain 
This study aims to describe current trends in Australia regarding chronic obstructive pulmonary disease (COPD) mortality and morbidity rates, and in its treatment and prevention from 2000 to 2010. The study’s purpose is to better define future directions in curbing COPD. People with COPD and their caregivers who attend patient support groups (n = 21), pulmonary rehabilitation group coordinators (n = 27) within Victoria, and the Australian Lung Foundation provided informed feedback. COPD was a leading underlying cause of death in both sexes during these years. Nevertheless, mortality rates declined from 1980 to 2007, with rates for males almost halving. Its prevalence has also substantially declined. Smoking rates have declined in age groups over 40 years old in both sexes. The COPD-X Plan provides evidence-based guidelines for the management of COPD. Many government, professional, and community initiatives have been recently implemented to promote the Plan. Two studies—one conducted before and one conducted after the publication of the COPD-X Plan—report some progress, but there are still very considerable departures from evidence-based practice. The Australian Lung Foundation estimates that only 1% of patients who could benefit from pulmonary rehabilitation programs have suitable access to such programs. A common priority for all informants was that there needed to be greater awareness of—and a more positive orientation to—COPD in both the Australian and health professional communities. The study concluded that substantial reductions in COPD and smoking cessation rates contrast with more limited progress toward adopting other aspects of evidence-based practice. The “good news” story concerning reductions in COPD disease with improving smoking cessation rates could form the basis for suitable media campaigns.

5.  Child Health Partnerships: a review of program characteristics, outcomes and their relationship 
Background
Novel approaches are increasingly employed to address the social determinants of health of children world-wide. Such approaches have included complex social programs involving multiple stakeholders from different sectors jointly working together (hereafter Child Health Partnerships). Previous reviews have questioned whether these programs have led to significant improvements in child health and related outcomes. We aim to provide definitive answers to this question as well as identifying the characteristics of successful partnerships.
Methods
A comprehensive literature search identified 11 major Child Health Partnerships in four comparable developed countries. A critical review is focused on various aspects of these including their target groups, program mechanics and outcomes.
Results and Conclusions
There was evidence of success in several major areas from the formation of effective joint operations of partners in different partnership models to improvement in both child wellbeing and parenting. There is emerging evidence that Child Health Partnerships are cost-effective. Population characteristics and local contexts need to be taken into account in the introduction and implementation of these programs.

6.  The effects of an area-based intervention on the uptake of maternal and child health assessments in Australia: A community trial 
Background
Recognition of the importance of the early years in determining health and educational attainment and promotion of the World Health Organization Health for All (HFA) principles has led to an international trend towards community-based initiatives to improve developmental outcomes among socio-economically disadvantaged children. In this study we examine whether, Best Start, an Australian area-based initiative to improve child health was effective in improving access to Maternal and Child Health (MCH) services.
Methods
The study compares access to information, parental confidence and annual 3.5 year Ages and Stages visiting rates before (2001/02) and after (2004/05) the introduction of Best Start. Access to information and parental confidence were measured in surveys of parents with 3 year old children. There were 1666 surveys in the first wave and 1838 surveys in the second wave. The analysis of visiting rates for the 3.5 year Ages and Stages visit included all eligible Victorian children. Best Start sites included 1,739 eligible children in 2001/02 and 1437 eligible children in 2004/05. The comparable figures in the rest of the state were and 45, 497 and 45, 953 respectively.
Results
There was a significant increase in attendance at the 3.5 year Ages and Stages visit in 2004/05 compared to 2001/02 in all areas. However the increase in attendance was significantly greater at Best Start sites than the rest of the state. Access to information and parental confidence improved over the course of the intervention in Best Start sites with MCH projects compared to other Best Start sites.
Conclusion
These results suggest that community-based initiatives in disadvantaged areas may improve parents' access to child health information, improve their confidence and increase MCH service use. These outcomes suggest such programmes could potentially contribute to strategies to reduce child health inequalities.

7.  Impact of telephone triage on emergency after hours GP Medicare usage: a time-series analysis 
Background
The Australian government sponsored trials aimed at addressing problems in after hours primary medical care service use in five different parts of the country with different after hours care problems. The study's objective was to determine in four of the five trials where telephone triage was the sole innovation, if there was a reduction in emergency GP after hours service utilization (GP first call-out) as measured in Medicare Benefits Schedule claim data. Monthly MBS claim data in both the pre-trial and trial periods was monitored over a 3-year period in each trial area as well as in a national sample outside the trial areas (National comparator). Poisson regression analysis was used in analysis.
Results
There was significant reduction in first call out MBS claims in three of the four study areas where stand-alone call centre services existed. These were the Statewide Call Centre in both its Metropolitan and Non-metropolitan areas in which it operated – Relative Risk (RR) = 0.87 (95% Confidence interval: 0.86 – 0.88) and 0.60 (95% CI: 0.54 – 0.68) respectively. There was also a reduction in the Regional Call Centre in the non-Metropolitan area in which it operated (RR = 0.46 (95% CI: 0.35 – 0.61) though a small increase in its Metropolitan area (RR = 1.11 (95% CI: 1.06 – 1.17). For the two telephone triage services embedded in existing organisations, there was also a significant reduction for the Deputising Service – RR = 0.62 (95% CI: 0.61 – 0.64) but no change in the Local Triage centre area.
Conclusion
The four telephone triage services were associated with reduced GP MBS claims for first callout after hours care in most study areas. It is possible that other factors could be responsible for some of this reduction, for example, MBS submitted claims for after hours GP services being reclassified from 'after hours' to 'in hours'. The goals of stand-alone call centres which are aimed principally at meeting population needs rather than managing demand may be being met only in part.

8.  Impact of standalone and embedded telephone triage systems on after hours primary medical care service utilisation and mix in Australia 
Background
The Australian government sponsored five local trials aimed at addressing problems in after hours (AH) primary medical care (PMC). The study's objective was to determine if the four trials, where telephone triage was the sole innovation, led to a reduction in AH service utilisation and change in service mix towards AH GP clinics. Changes in utilisation and mix of AH GP clinic and home visits, ED and ambulance use were monitored in the trial areas, and in a national sample to adjust for the effects of secular trend. Pre- and post-trial telephone surveys of two separate random samples of approximately 350 AH PMC user households in each area were conducted.
Results
Some types of AH PMC use became more frequent in both of the standalone services using nurse-administered proprietary call centre software, which were aimed at better addressing population need (Statewide call centre; Regional call centre). Service use overall (95%CI: 1.03–1.83) and GP clinic use (95%CI: 1.07–2.00) increased in the metro area of the Statewide call centre and in GP clinic (95%CI: 1.04–2.14) and home visits (95%CI: 1.03–3.91) in the non-metro area of the Regional call centre. Service mix only changed in the non-metro area of the Regional call centre with increased contact in GP home visits (95%CI: 1.02–4.38). Levels of use remained unchanged in both embedded services using other than proprietary software, which were established to support the GP workforce (Deputising service; Local triage centre). Service mix only changed in the Deputising service with a change away from AH GP clinics in both contact (95%CI: 0.39–0.97) and frequency (95% CI: -2.12 – -0.7).
Conclusion
Bearing in mind limitations in estimating AH PMC utilisation levels and mix, it is concluded that the impacts of telephone triage were generally smaller in Australia than reported elsewhere. There were different impacts on levels of service utilisation and service mix in standalone call centres and embedded services. Impacts of telephone triage on service utilisation and mix are influenced by the type of telephone triage offered, the goals of the agency providing the service, as well as local factors. (345 words)

9.  Comparison of the uptake of health assessment items for Aboriginal and Torres Strait Islander people and other Australians: Implications for policy 
Background
Health Assessment (HA) items were introduced in 1999 for Aboriginal and Torres Strait Islander people aged at least 55 years and all Australians aged over 75 years. In 2004 a new item was introduced for HAs among adult Aboriginal and Torres Strait Islander people aged 15–54 years. The new item has been applauded as a major policy innovation however this enthusiasm has been tempered with concern about potential barriers to its uptake. In this study we aim to determine whether there are disparities in uptake of HA items for Aboriginal and Torres Strait Islander people compared to other Australians.
Method
The analysis was based on Health Insurance Commission data. Indigenous status was ascertained based on the item number used. Logistic regression was used to compare uptake of HA items for older people among Aboriginal and Torres Strait Islander people compared to other Australians. Adjustments were made for dual eligibility. Uptake of the HA items for older people was compared to the uptake of the new item for Aboriginal and Torres Strait Islander people aged 15–44 years.
Results
Our analyses suggest a significant and persistent disparity in the uptake of items for older patients among Aboriginal and Torres Strait Islander people compared to other Australians. A similar disparity appears to exist in the uptake of the new adult Aboriginal and Torres Strait Islander HA item.
Conclusion
Further engagement of primary care providers and the community around the uptake of the new HA items may be required to ensure that the anticipated health benefits eventuate.

10.  Strengthening Medicare: Will increasing the bulk-billing rate and supply of general practitioners increase access to Medicare-funded general practitioner services and does rurality matter? 
Background
Recent increases in the bulk-billing rate have been taken as an indication that the Federal government's Strengthening Medicare initiative, and particularly the bulk-billing incentives, are 'working'. Given the enduring geographic differences in the supply of general practitioners (GPs) it is timely to reconsider the impact that this increase in the provision of 'free care' will have on access to Medicare-funded GP services in rural and urban areas of Australia. Utilisation has been modelled as two different stochastic processes: the decision to consult and the frequency of consultation.
Results
In the decision to consult model the supply of FFS GPs is a more important predictor of utilisation than the bulk-billing rate. Paradoxically the modelling predicts that ceteris paribus increases in either GP supply or the bulk-billing rate appear to have perverse effects in some areas by decreasing utilisation. In the frequency of consultation model, GP density is not a predictor and increasing the bulk-billing rate will unambiguously increase the frequency of consultation across all areas. In both models, the positive impacts associated with changes in supply and cost are constrained outside the inner metropolitan area by reduced geographic accessibility to Medicare-funded GP services. The modelling also shows that people are more likely to consult a GP in areas of high socioeconomic disadvantage, although socioeconomic status is not a predictor of frequency of consultation.
Conclusion
Bulk-billing rates and the supply of FFS GPs are important features of the Australian health care system that are, potentially, amenable to policy manipulation. The implications of this research are that government policies designed to achieve similarity in these characteristics across geographic areas will not result in equity of access because they fail to address problems caused by geographic inaccessibility in rural and remote areas. Attempting to increase bulk-billing rates in some of these areas may, in fact, reduce access to FFS GP services.
