Implementing a self-management intervention for people with a chronic compensable musculoskeletal injury in a workers compensation context: a process evaluation.

PURPOSE: Determining factors critical for an intervention's success, specifically for whom and under what circumstances, is necessary if interventions are to be effectively targeted and efficiently implemented. This paper describes a process evaluation undertaken to assess the implementation of a novel self-management (SM) intervention developed for those with a chronic compensable work-related musculoskeletal disorder seeking to return to work. METHODS: The process evaluation, assessing the 'Self-Management for Return to Work' intervention, examined data from program leader evaluations, telephone interviews with stakeholders (injured worker participants, vocational rehabilitation consultant program leaders and compensation insurance regulators), post-intervention focus group session feedback, attendance lists and researcher notes. RESULTS: The evaluation identified several challenges and barriers associated with conducting research within the VR environment and with the characteristics of those targeted i.e., injured workers with a chronic compensable condition. These issues were primary contributing factors to the modifications to the randomised controlled trial methodology and the trial's premature cessation. CONCLUSIONS: Despite the difficulties encountered, high stakeholder acceptability suggests that the concept and theory underlying the targeted SM intervention were not flawed, though there is room for further tailoring to both the program method and its timing. The results of this process evaluation provide a useful platform for others considering the implementation of interventions within the vocational rehabilitation context or with individuals with chronic, compensated injuries.

The health and cost implications of high body mass index in Australian defence force personnel.

BACKGROUND: Frequent illness and injury among workers with high body mass index (BMI) can raise the costs of employee healthcare and reduce workforce maintenance and productivity. These issues are particularly important in vocational settings such as the military, which require good physical health, regular attendance and teamwork to operate efficiently. The purpose of this study was to compare the incidence of injury and illness, absenteeism, productivity, healthcare usage and administrative outcomes among Australian Defence Force personnel with varying BMI. METHODS: Personnel were grouped into cohorts according to the following ranges for (BMI): normal (18.5 - 24.9 kg/m2; n = 197), overweight (25-29.9 kg/m2; n = 154) and obese (≥30 kg/m2) with restricted body fat (≤28% for females, ≤24% for males) (n = 148) and with no restriction on body fat (n = 180). Medical records for each individual were audited retrospectively to record the incidence of injury and illness, absenteeism, productivity, healthcare usage (i.e., consultation with medical specialists, hospital stays, medical investigations, prescriptions) and administrative outcomes (e.g., discharge from service) over one year. These data were then grouped and compared between the cohorts. RESULTS: The prevalence of injury and illness, cost of medical specialist consultations and cost of medical scans were all higher (p < 0.05) in both obese cohorts compared with the normal cohort. The estimated productivity losses from restricted work days were also higher (p < 0.05) in the obese cohort with no restriction on body fat compared with the normal cohort. Within the obese cohort, the prevalence of injury and illness, healthcare usage and productivity were not significantly greater in the obese cohort with no restriction on body fat compared with the cohort with restricted body fat. The number of restricted work days, the rate of re-classification of Medical Employment Classification and the rate of discharge from service were similar between all four cohorts. CONCLUSIONS: High BMI in the military increases healthcare usage, but does not disrupt workforce maintenance. The greater prevalence of injury and illness, greater healthcare usage and lower productivity in obese Australian Defence Force personnel is not related to higher levels of body fat.

Are we there yet? Australian road safety targets and road traffic crash fatalities.

BACKGROUND: Road safety targets are widely used and provide a basis for evaluating progress in road safety outcomes against a quantified goal. In Australia, a reduction in fatalities from road traffic crashes (RTCs) is a public policy objective: a national target of no more than 5.6 fatalities per 100,000 population by 2010 was set in 2001. The purpose of this paper is to examine the progress Australia and its states and territories have made in reducing RTC fatalities, and to estimate when the 2010 target may be reached by the jurisdictions. METHODS: Following a descriptive analysis, univariate time-series models estimate past trends in fatality rates over recent decades. Data for differing time periods are analysed and different trend specifications estimated. Preferred models were selected on the basis of statistical criteria and the period covered by the data. The results of preferred regressions are used to determine out-of-sample forecasts of when the national target may be attained by the jurisdictions. Though there are limitations with the time series approach used, inadequate data precluded the estimation of a full causal/structural model. RESULTS: Statistically significant reductions in fatality rates since 1971 were found for all jurisdictions with the national rate decreasing on average, 3% per year since 1992. However the gains have varied across time and space, with percent changes in fatality rates ranging from an 8% increase in New South Wales 1972-1981 to a 46% decrease in Queensland 1982-1991. Based on an estimate of past trends, it is possible that the target set for 2010 may not be reached nationally, until 2016. Unsurprisingly, the analysis indicated a range of outcomes for the respective state/territory jurisdictions though these results should be interpreted with caution due to different assumptions and length of data. CONCLUSIONS: Results indicate that while Australia has been successful over recent decades in reducing RTC mortality, an important gap between aspirations and achievements remains. Moreover, unless there are fairly radical ("trend-breaking") changes in the factors that affect the incidence of RTC fatalities, deaths from RTCs are likely to remain above the national target in some areas of Australia, for years to come.

Does self-management for return to work increase the effectiveness of vocational rehabilitation for chronic compensated musculoskeletal disorders? Protocol for a randomised controlled trial.

BACKGROUND: Musculoskeletal disorders are common and costly disorders to workers compensation and motor accident insurance systems and are a leading contributor to the burden of ill-health. In Australia, vocational rehabilitation is provided to workers to assist them to stay in, or return to work. Self-management training may be an innovative addition to improve health and employment outcomes from vocational rehabilitation. METHODS/DESIGN: The research plan contains mixed methodology consisting of a single blind randomised controlled trial, an economic evaluation and qualitative research. Participants (n = 366) are volunteers with compensated musculoskeletal disorders of 3 months to 3 years in duration who were working at the time of the injury/onset of the chronic disorder. The trial tests the effectiveness of usual vocational rehabilitation plus the Chronic Disease Self-Management Program (CDSMP) to which two additional and newly-developed modules have been added, against vocational rehabilitation alone (control) The modules added to the CDSMP focus on how to navigate through compensation systems and manage the return to work process, and aim to be relevant to those in a vocational rehabilitation setting.The primary outcome of this study is readiness for return to work which will be evaluated using the Readiness for Return-to-Work scale. Secondary outcomes include return to work status, health efficacy (heiQ questionnaire) and general health status (SF-12v2(R) Health Survey). Measures will be taken at baseline, immediately post-intervention and at 6- and 12- months post-intervention by an independent assessor. An economic evaluation will compare the costs and outcomes between the intervention and control groups in terms of cost-effectiveness and a partial cost-benefit or cost analysis. The impact of the intervention will also be evaluated qualitatively, in terms of its acceptability to stakeholders. DISCUSSION: This article describes the protocol for a single blind randomised controlled trial with a one year follow-up. The results will provide evidence for the addition or not of self-management training within vocational rehabilitation for chronic compensated musculoskeletal disorders.

Are road traffic crash fatality rates converging among OECD countries?

This article examines the trends of road traffic crash (RTC) fatality rates in OECD countries over the past four decades. Based on recent developments in the economic growth literature we propose and test the hypothesis that RTC fatality rates initially increase with economic development, peak, and then gradually decrease. The theory predicts that, as a result, the RTC fatality rates of different countries will tend to converge over time. Our results for the period 1961-2007 reveal no evidence of the convergence of RTC fatality rates across the OECD as a whole for that time period. Nevertheless, there is evidence of convergence among sub-groups of countries. This evidence may assist policymakers as an additional way of benchmarking their country's performance against that of its peers and to identify the next-closest peer in country sub-groups with superior road safety performance.

Does injury compensation lead to worse health after whiplash? A systematic review.

One might expect that injury compensation would leave injured parties better off than they would otherwise have been, yet many believe that compensation does more harm than good. This study systematically reviews the evidence on this "compensation hypothesis" in relation to compensable whiplash injuries. PubMed, CINAHL, EMBASE, PEDro, PsycInfo, CCTR, Lexis, and EconLit were searched from the date of their inception to April 2010 to locate longitudinal studies, published in English, comparing the health outcomes of adults exposed/not exposed to compensation-related factors. Studies concerning serious neck injuries, using claimants only, or using proxy measures of health outcomes were excluded. Eleven studies were included. These examined the effect of lawyer involvement, litigation, claim submission, or previous claims on pain and other health outcomes. Among the 16 results reported were 9 statistically significant negative associations between compensation-related factors and health outcomes. Irrespective of the compensation-related factor involved and the health outcome measured, the quality of these studies was similar to studies that did not find a significant negative association: most took some measures to address selection bias, confounding, and measurement bias, and none resolved the potential for reverse causality bias that arises in the relationship between compensation-related factors and health. Unless ambiguous causal pathways are addressed, one cannot draw conclusions from statistical associations, regardless of their statistical significance and the extent of measures to address other sources of bias. Consequently, there is no clear evidence to support the idea that compensation and its related processes lead to worse health.

Public policy and the dependency of nursing home residents in Australia: 1968-69 to 2006-07.

OBJECTIVE: The purpose of this paper is to derive annual estimates of the aggregate dependency of the nursing home population in Australia, and to use these data to consider the impact of Government policies to target nursing home services to those with high care-needs/dependency. Two related tools, the 'Aggregate Dependency Value' and 'Aggregate Dependency Index', have been constructed using the principles of case-mixed based systems, to quantify the aggregate dependency of residents. Data on all residents 1968-1969 to 2006-2007, and on newly admitted residents 1992-1993 to 2006-2007 have been derived and analysed. METHODS: To construct the tools, the percent of residents classified into various dependency categories were weighted by proxy measures of their dependency. These were summed, and converted into index numbers to estimate rates of change in the aggregate dependency of residents. The derived data were used to consider possible impacts of the policies. RESULTS: The data indicate that the dependency of residents has, for the most part, increased over recent decades but that the rate of the increase has varied. An increase in the dependency of residents corresponds with the policies' objectives. CONCLUSIONS: The tools extend the ways the dependency of nursing home residents in Australia can be assessed. The estimates support the effectiveness of the Government's targeting policies but causal relationships have not been estimated.

The introduction of a targeted user-pays approach to funding high-level residential aged care in Australia: an empirical investigation of the impact on price.

In response to predictions that population ageing will increase government spending over the coming decades, in 1997-98, the Australian Government introduced means-tested income fees and accommodation charges for those admitted to nursing homes with income and assets above set threshold levels. Immediately prior, all residents paid the same price for their care and were not required to contribute towards the cost of their accommodation. In addition, in relation to those eligible to pay a higher price, the Government reduced its subsidisation of the cost of their care. The Government anticipated that the initiative would more equitably share the cost of age-related services across the public and private sectors, and result in some cost savings for itself. The purpose of this study is to assess the impact of the policy on the average price paid by residents. The findings suggest that the policy may have contributed to an increase in the average price paid, but statistical evidence is limited due to a number of data issues. Results also indicate that the rate of increase in the price was greater after the Residential Aged Care Structural Reform package was introduced. The study contributes to the economic analysis of the sector by evaluating time series estimates of prices paid by residents since the early 1970s.
