How Much Physiotherapy, Chiropractic, and Osteopathy Care Do Compensated Australian Workers with Low Back Pain Receive? A Retrospective Cohort Study.

OBJECTIVES: To identify the prevalence and frequency of physiotherapy, chiropractic, and/or osteopathy care in Australians with workers' compensation claims for low back pain (LBP). METHODS: We included workers with accepted workers' compensation claims longer than 2 weeks from the Australian states of Victoria, Queensland, South Australia, and Western Australia. Workers were grouped by whether they attended physiotherapy, chiropractic, and/or osteopathy in the first 2 years of their claim. Descriptive statistics and logistic regression were used to describe differences between groups. Descriptive statistics and negative binomial regression were used to describe differences in the number of attendances in each group. RESULTS: Most workers had at least one physical therapy attendance during the period of their claim (n = 23,619, 82.0%). Worker state, socioeconomic status, and remoteness were the largest contributing factors to likelihood of physical therapy attendance. Most workers only attended physiotherapy (n = 21,035, 89.1%, median of 13 times). Far fewer only attended chiropractic (n = 528, 2.2%, median of 8 times) or only osteopathy (n = 296, 1.3%, median of 10 times), while 1,750 (7.5%) attended for care with more than one type of physical therapy (median of 31 times). CONCLUSION: Most Australian workers with workers' compensation time loss claims for LBP attend physiotherapy at least once during their claims. State of claim is the strongest predictor of which physical therapy profession they attend, possibly due to regional availability. Workers who see a physiotherapist have significantly more attendances. Future research should explore the relationship between these patterns of care and claimant outcomes, including work disability duration.

The Association of Physiotherapy Continuity of Care with Duration of Time Loss Among Compensated Australian Workers with Low Back Pain.

PURPOSE: The aims of this study are to determine how continuous the care provided by physiotherapists to compensated workers with low back pain is, what factors are associated with physiotherapy continuity of care (CoC; treatment by the same provider), and what the association between physiotherapy CoC and duration of working time loss is. METHODS: Workers' compensation claims and payments data from Victoria and South Australia were analysed. Continuity of care was measured with the usual provider continuity metric. Binary logistic regression examined factors associated with CoC. Cox regression models examined the association between working time loss and CoC. RESULTS: Thirty-six percent of workers experienced complete CoC, 25.8% high CoC, 26.1% moderate CoC, and 11.7% low CoC. Odds of complete CoC decreased with increased service volume. With decreasing CoC, there was significantly longer duration of compensated time loss. CONCLUSION: Higher CoC with a physiotherapist is associated with shorter compensated working time loss duration for Australian workers with low back pain.

Patterns of physiotherapy attendance in compensated Australian workers with low back pain: a retrospective cohort study.

ABSTRACT: Workers with low back pain (LBP) frequently seek care from physiotherapists. We sought to identify patterns of physiotherapy attendance and factors associated with these patterns in Australian workers with accepted compensation claims for LBP. We included workers with accepted workers' compensation claims for LBP from 4 Australian states between 2011 and 2015. We used trajectory modelling to identify distinct groups of workers based on the number (ie, volume) of monthly physiotherapy attendances over a 2-year period from claim acceptance. Descriptive statistics and logistic regression models were used to compare the characteristics of the groups. A small but significant proportion attend numerous times over a long period. 79.0% of the sample (N = 22,767) attended physiotherapy at least once in the 2 years after claim acceptance. Among these, trajectory modelling identified 4 distinct patterns of attendance. Most (N = 11,808, 51.9%) recorded a short-term low-volume pattern, 26.8% (n = 6089) recorded a short-term high-volume pattern, 14.3% (n = 3255) recorded a long-term low-volume pattern, and 7.1% (n = 1615) recorded a long-term high-volume pattern. Workers from Victoria (OR 0.34, 99% CI 0.31, 0.37), South Australia (OR 0.69, 99% CI 0.60, 0.80), and Western Australia (OR 0.79, 99% CI 0.69, 0.88) were significantly less likely to attend physiotherapy than workers from Queensland. Victorian workers were significantly more likely to be in one of the 2 long-term trajectory groups (OR 8.17, 99% CI 6.86, 9.73; OR 18.68, 99% CI 13.57, 25.70). In conclusion, most compensated Australian workers with LBP attend physiotherapy. Significant interjurisdictional differences between attendance patterns suggests that policy may play an important role in healthcare delivery.

Capture, Coding, and Reporting of Health Care and Medicine Information in Australian Workers' Compensation Systems.

OBJECTIVE: This study aims to characterize the approaches to collecting, coding, and reporting health care and medicines data within Australian workers' compensation schemes. METHODS: We conducted a cross-sectional survey of data and information professionals in major Australian workers' compensation jurisdictions. Questionnaires were developed with input from key informants and a review of existing documentation. RESULTS: Twenty-five participants representing regulators (40%) and insurers (60%) with representation from all Australian jurisdictions were included. Health care and medicines data sources, depth, coding standards, and reporting practices exhibited significant variability across the Australian workers' compensation schemes. CONCLUSIONS: Substantial variability exists in the capture, coding, and reporting of health care and medicine data in Australian workers' compensation jurisdictions. There are opportunities to advance understanding of medicines and health service delivery in these schemes through greater harmonization of data collection, data coding, and reporting.

Development and initial application of a harmonised multi-jurisdiction work injury compensation database.

Objectives: Workers' compensation schemes provide funding for wage replacement and healthcare for injured and ill workers. In Australia, workers' compensation schemes operate independently in different jurisdictions, making comparisons of health service use challenging. We sought to develop and deploy a new database of health service and income support data, harmonising data from multiple Australian workers' compensation jurisdictions. Methods: We worked with workers' compensation authorities from six Australian jurisdictions to combine claims, healthcare, medicines and wage replacement data for a sample of compensated workers with claims for musculoskeletal conditions. We designed a structured relational database and developed a bespoke health services coding scheme to harmonise data across jurisdictions. Results: The Multi-Jurisdiction Workers' Compensation Database contains four data sets: claims, services, medicines and wage replacement. The claims data set contains 158,946 claims for low back pain (49.6%), limb fracture (23.8%) and non-specific limb conditions (26.7%). The services data set contains a total of 4.2 million cleaned and harmonised services including doctors (29.9%), physical therapists (56.3%), psychological therapists (2.8%), diagnostic procedures (5.5%) and examinations and assessments (5.6%). The medicines data set contains 524,380 medicine dispenses, with 208,504 (39.8%) dispenses for opioid analgesics. Conclusions: The development of this database presents potential opportunities to gain a greater understanding of health service use in the Australian workers' compensation sector, to measure the impact of policy change on health services and to provide a method for further data harmonisation. Future efforts could seek to conduct linkage with other data sources.

The Association Between Continuity of Care With a Primary Care Physician and Duration of Work Disability for Low Back Pain: A Retrospective Cohort Study.

OBJECTIVES: The aims of the study are to determine the continuity of care (CoC) provided by primary care physicians among workers with low back pain, to identify factors associated with CoC, and to investigate whether CoC is associated with working time loss. METHODS: Continuity of care was measured with the usual provider continuity metric. Ordinal logistic regression models examined factors associated with CoC. Quantile regression models examined the association between working time loss and CoC. RESULTS: Complete CoC was observed in 33.8% of workers, high CoC among 37.7%, moderate CoC in 22.1%, and low CoC in 6.4%. In workers with more than 2-months time loss, those with complete CoC had less time off work. CONCLUSIONS: Higher CoC with a primary care physician is associated with less working time loss and this relationship is strongest in the subacute phase of low back pain.

Assessment of a new tool to improve case manager identification of delayed return to work in the first two weeks of a workers' compensation claim.

OBJECTIVE: To determine whether the Plan of Action for a Case (PACE) tool improved identification of workers at risk of delayed return to work. DESIGN: Prospective cohort of workers with accepted workers' compensation claims in the state of New South Wales, Australia. INTERVENTIONS: The 41-item PACE tool was completed by the case manager within the first two weeks of a claim. The tool gathered information from the worker, employer and treating practitioner. Multivariate logistic regression models predicted work time loss of at least one and three months. RESULTS: There were 524 claimants with complete PACE information. A total of 195 (37.2%) had work time loss of at least one month and 83 (15.8%) had time loss of at least three months. Being male, injury location, an Orebro Musculoskeletal Pain Screening Questionnaire-Short Form score >50, having a small employer, suitable duties not being available, being certified unfit, and the worker having low one-month recovery expectations predicted time loss of over one month. For three months, injury location, a Short Form Orebro score >50, no return-to-work coordinator, and being certified unfit were significant predictors. The model incorporating PACE information provided a significantly better prediction of both one- and three-month outcomes than baseline information (area-under-the-curve statistics-one month: 0.85 and 0.68, respectively; three months: 0.85 and 0.69, respectively; both P < 0.001). CONCLUSION: The PACE tool improved the ability to identify workers at risk of ongoing work disability and identified modifiable factors suited to case manager-led intervention.

The Impact of Income Sources on Financial Stress in Workers' Compensation Claimants.

PURPOSE: Workers' compensation schemes usually recompense workers below their regular wage. This may cause financial stress, which has previously been associated with poorer health and work outcomes after injury. We sought to determine the level of financial stress experienced by injured workers and the influence of post-injury income source on financial stress. METHODS: Analysis of a cross-sectional national survey of 4532 adults who had been injured at work and had at least one day of workers' compensation paid. Financial stress at time of survey was measured on a scale of 1-10 and subsequently dichotomised at the top quartile for further analysis. The effect of current main income source on financial stress, adjusted for demographic and psychosocial confounders, was assessed using logistic regression. RESULTS: Sixty-nine percent of workers whose main income was social assistance or insurance and 54% whose main income was workers' compensation were experiencing financial stress. Relative to wages or salaries, workers with a main income from social assistance or insurance (odds ratio: 3.33, 95% CI 2.22-5.00) and workers' compensation (1.71, 1.31-2.24) had higher odds of financial stress. Workers with a main income of an aged pension or superannuation had lower odds of financial stress (0.52, 0.28-0.97). CONCLUSION: Injured workers receiving workers' compensation or social assistance benefits are vulnerable to increased financial stress. Given the potential negative consequences of financial stress on health, particularly mental health, this study suggests the need for careful consideration of income replacement benefits in the design of workers' compensation schemes.

Factors Associated with Employer Support for Injured Workers During a Workers' Compensation Claim.

Purpose The employer/worker relationship can be an important catalyst for-or obstacle to-successful return to work (RTW). An understanding of factors associated with an injured worker's relationship with their employer, and employer involvement in RTW planning, is warranted. Methods Analysis of n = 8808 cross-sectional survey responses from injured workers in nine Australian workers' compensation (WC) jurisdictions. Workers completed a telephone survey between 6 and 24 months post-WC claim acceptance. Factors associated with the worker's perception of employer support were examined using ordinal regression. Factors associated with employer provision of RTW plans were examined using logistic regression. Results Factors associated with employer support included being aged over 50 years, not having a mental health condition, better self-rated health and less time between injury and claim. Factors associated with having a RTW plan included being female, not having a mental health condition and working for a self-insurer. Factors associated with having a written RTW plan included being female and being under 50 years. There was wide variation in the provision of RTW plans between WC jurisdictions. Conclusions There are strong associations between worker, claim and injury-related factors and the injured worker's experience of employer support. Identification of workers at risk of receiving inadequate support during the RTW process may enable interventions to improve support and RTW outcomes.

Concerns About Claiming, Postclaim Support, and Return to Work Planning: The Workplace's Impact on Return to Work.

OBJECTIVE: The aim of this study was to determine how injured Australian workers perceived employer emotional (eg, empathy) and instrumental [eg, return-to-work (RTW) planning] support during the RTW process and examine associations between support and RTW. METHODS: Using data from the 2014 National Return to Work Survey of injured workers with a workers' compensation claim, multinomial regression models examined relationships between support and RTW. RESULTS: Receiving support and developing RTW plans were significantly associated with a greater likelihood of RTW. When controlled for one another in a single model, postclaim support had the strongest association with RTW, with RTW planning also significantly and positively associated with RTW. CONCLUSION: Provision of both emotional and instrumental support are important employer-led work disability management interventions. Research is required to develop strategies for increasing employer support to lead to improved RTW outcomes for injured workers.
