The Digital Economy and Hybrid Work Call for a Review of Compensation Criteria for Musculoskeletal Disorders.

Work-related musculoskeletal disorders (WRMSD) pose a significant occupational health challenge in Europe. The digitization of the economy substantially reshaped the nature and organization of work. The proliferation of hybrid working, characterized by a combination of office-based and remote work, has been accelerated by the COVID-19 pandemic. This review covers hybrid forms of work, their impact on WRMSDs, and the potential implications for WRMSD compensation. Approximately 30-40% of the European workforce could potentially transition to hybrid forms of work. Hybrid work arrangements can result in prolonged static postures of the trunk, neck, and upper limbs without adequate breaks, thereby increasing the risk of neck and lower back pain. As teleworking and hybrid working become more prevalent, an increase in non-specific WRMSDs is anticipated among the working population. In many countries, claims for WRMSDs necessitate a formal diagnosis by a healthcare professional. However, cases of non-specific WRMSDs, such as cervicalgia or chronic shoulder pain, - commonly observed in sedentary workers engaged in predominantly low-intensity, prolonged static work amid visually and cognitively demanding tasks - often do not meet the criteria for compensation as occupational diseases. The compensation system and/or the criteria for compensation must be adapted to accommodate the rise of telework, necessitating evolving criteria for compensation that address both medical and risk exposure considerations.

Workers' compensation costs for healthcare caregivers: Home healthcare, long-term care, and hospital nurses and nursing aides.

BACKGROUND: Healthcare workers (nurses and nursing aides) often have different exposures and injury risk factors depending on their occupational subsector and location (hospital, long-term care, or home health care). METHODS: A total of 5234 compensation claims for nurses and nursing aides who suffered injuries to their lower back, knee, and/or shoulder over a 5-year period were obtained from the Ohio Bureau of Workers' Compensation and analyzed. Injury causation data was also collected for each claim. The outcome variables included indemnity costs, medical costs, total costs, and the number of lost work days. The highest prescribed morphine equivalent dose for opioid medications was also calculated for each claim. RESULTS: Home healthcare nurses and nursing aides had the highest average total costs per claim. Hospital nurses and nursing aides had the highest total claim costs, of $5 million/year. Shoulder injuries for home healthcare nursing aides (HHNAs) had the highest average total claim costs ($20,600/injury) for all occupation, setting, and body area combinations. Opioids were most frequently prescribed for home healthcare nurses (HHNs) and nursing aides (18.9% and 17.7% having been prescribed opioids, respectively). Overexertion was the most common cause for HHN and nursing aide claims. CONCLUSIONS: With the rapidly expanding workforce in the home healthcare sector, there is a potential health crisis from the continued expansion of home healthcare worker injuries and their associated costs. In addition, the potential for opioid drug usage places these workers at risk for future dependence, overdose, and prolonged disability. Future research is needed to investigate the specific and ideally reversible causes of injury in claims categorized as caused by overexertion.

Work-related asthma surveillance in Washington State: time trends, industry rates, and workers' compensation costs, 2002-2016.

Objective: Washington State's work-related asthma (WRA) surveillance program utilizes workers' compensation (WC) data as its primary data source and has spanned a 15-year time period. This study analyses trends for WRA claim incidence rates compared to all WC claim incidence rates. WRA claim incidence rates and WC costs are analyzed by industry. Methods: Potential WRA cases were identified through the WC system and through direct provider report and classified by industry, age, and year of illness onset. WRA claim rates by industry and year were calculated using total work hours reported by employers covered by the WC system. Claim costs for accepted claims were compared by industry and year. Results: WRA claim incidence rates decreased 8.9% (95% CI: -10.6, -7.2) annually for the time period 2002-2016. The decline in WRA claim incidence rate is slightly faster than the incidence rate for all WC claims which had its steepest decrease from 2007 to 2010 at an estimated annual 8.4% decrease (95% CI: -11.8, -5.0). WRA claim rates were highest for workers in Public Administration, Manufacturing, and the Agricultural, Forestry, Fishing and Hunting industries. Median claim costs for WRA did not change significantly by year (p = 0.2, range $595-$1442) and the distribution of WRA WC claim costs by industry were highest in Manufacturing (21.3%) and Construction (16.4%) industries. Conclusion: WRA claim incidence rates are declining in Washington State. The cause for the decline is unclear. Workers across all industries in Washington remain at risk for WRA.

Step-downs reduce workers' compensation payments to encourage return to work: are they effective?

OBJECTIVE: To determine whether step-downs, which cut the rate of compensation paid to injured workers after they have been on benefits for several months, are effective as a return to work incentive. METHODS: We aggregated administrative claims data from seven Australian workers' compensation systems to calculate weekly scheme exit rates, a proxy for return to work. Jurisdictions were further subdivided into four injury subgroups: fractures, musculoskeletal, mental health and other trauma. The effect of step-downs on scheme exit was tested using a regression discontinuity design. Results were pooled into meta-analyses to calculate combined effects and the proportion of variance attributable to heterogeneity. RESULTS: The combined effect of step-downs was a 0.86 percentage point (95% CI -1.45 to -0.27) reduction in the exit rate, with significant heterogeneity between jurisdictions (I2=68%, p=0.003). Neither timing nor magnitude of step-downs was a significant moderator of effects. Within injury subgroups, only fractures had a significant combined effect (-0.84, 95% CI -1.61 to -0.07). Sensitivity analysis indicated potential effects within mental health and musculoskeletal conditions as well. CONCLUSIONS: The results suggest some workers' compensation recipients anticipate step-downs and exit the system early to avoid the reduction in income. However, the effects were small and suggest step-downs have marginal practical significance. We conclude that step-downs are generally ineffective as a return to work policy initiative.Postprint link: https://www.medrxiv.org/content/10.1101/19012286.

Analysis of Thoroughbred horse farm workers' compensation insurance claims in Kentucky: Injury frequency, cost, lost time, and associated occupational factors.

BACKGROUND: Thoroughbred horse farm workers self-report a high frequency of work-related injuries and pain. However, an analysis of Thoroughbred horse farm workers' compensation injury claims is absent from the literature, yet may benefit worker safety. METHODS: We analyzed workers' compensation insurance firm data containing 2276 claims filed between 2008 and 2015. Injury frequency, cost, and lost time per cause, nature, and body part injured were examined qualitatively and via univariate tests. Factors associated with high cost and high duration lost time claims were modeled via multivariable logistic regression. RESULTS: The average Thoroughbred worker claim cost $4,198 and accrued 10 days lost time, involving strikes (57% of total claims), sprains/strains (34%), and wrist/hand injuries (18%). Injuries primarily occurred on mornings (54%), weekdays (79%), and during the transition from breeding to sales (23%). Jobs with a high level of horse contact had significantly higher cost ($6,487) and higher duration lost time (16.8 days) claims, with significantly higher cost claims on the weekends ($6,471) and from the oldest workers ($7466), vs reference groups. Logistic models indicate significantly increased odds of a high-cost injury among high horse contact jobs (OR = 1.87; 95% C.I. = 1.53-2.29) and older age tertiles (1.38; 1.08-1.75; 1.70, 1.32-2.18). The odds of a high duration lost time injury are significantly increased among high horse contact jobs (1.91; 1.53-2.39) and males (1.50, 1.13-1.98), with significantly reduced odds among the most tenured workers (0.74; 0.56-0.99). CONCLUSIONS: Our findings elucidate factors to reduce injury frequency, cost, and lost time among Thoroughbred horse farm workers.

Implementation of Early Intervention Protocol in Australia for 'High Risk' Injured Workers is Associated with Fewer Lost Work Days Over 2 Years Than Usual (Stepped) Care.

Purpose To evaluate whether a protocol for early intervention addressing the psychosocial risk factors for delayed return to work in workers with soft tissue injuries would achieve better long-term outcomes than usual (stepped) care. Methods The study used a controlled, non-randomised prospective design to compare two case management approaches. For the intervention condition, workers screened within 1-3 weeks of injury as being at high risk of delayed returned to work by the Örebro Musculoskeletal Pain Screening Questionnaire-short version (ÖMPSQ-SF) were offered psychological assessment and a comprehensive protocol to address the identified obstacles for return to work. Similarly identified injured workers in the control condition were managed under usual (stepped) care arrangements. Results At 2-year follow-up, the mean lost work days for the Intervention group was less than half that of the usual care group, their claim costs were 30% lower, as was the growth trajectory of their costs after 11 months. Conclusions The findings supported the hypothesis that brief psychological risk factor screening, combined with a protocol for active collaboration between key stakeholders to address identified psychological and workplace factors for delayed return to work, can achieve better return on investment than usual (stepped) care.

Reexamining the persisting wage gap between male and female PAs.

OBJECTIVE: To determine the magnitude of any difference in total compensation between male and female physician assistants (PAs) after controlling for personal and workplace factors related to compensation. METHODS: Using data from the 2019 AAPA Salary Survey, the authors conducted a sequential regression analysis to examine the relationship between a variety of personal and practice demographics and total compensation. RESULTS: After controlling for compensation-related factors, a wage gap between male and female PAs persisted: female PAs were paid almost $0.93 for every $1 male PAs were paid in the first year of work ($9,010 less). This wage gap widened by $201 for every year of work experience. CONCLUSIONS: A wage gap between male and female PAs persists even after including all compensation types and controlling for compensation-related factors that may differ between male and female PAs. Proposed policy implications could begin to mitigate the gap.

An Evidence-Based Care Model for Workers With Concussion.

OBJECTIVE: To evaluate the impact of an evidence-based assessment program for people with workers' compensation claims for concussion on healthcare utilization and duration of lost time from work. SETTING: An assessment program for people with a work-related concussion was introduced to provide physician assessment focused on education and appropriate triage. PARTICIPANTS: A total of 3865 people with accepted workers' compensation claims for concussion with dates of injury between January 1, 2014, and February 28, 2017. DESIGN: A quasiexperimental pre-/poststudy of healthcare utilization (measured by healthcare costs) and duration of time off work (measured by loss of earnings benefits) in a cohort of people with workers' compensation claims for concussion in the period prior to and following introduction of a new assessment program. Administrative data were retrospectively analyzed to compare outcomes in patients from the preassessment program implementation period to those in the postimplementation period. RESULTS: The assessment program resulted in reduced healthcare utilization reflected by a 14.4% (95% confidence interval, -28.7% to -0.8%) decrease in healthcare costs. The greatest decrease in healthcare costs was for assessment services (-27.9%) followed by diagnostic services (-25.7%). There was no significant difference in time off work as measured by loss-of-earnings benefits. CONCLUSION: A care model for people with a work-related concussion involving an evidence-based assessment by a single physician focused on patient education resulted in significantly decreased healthcare utilization without increasing duration of time off work.

Usefulness of a job-exposure matrix 'MADE' as a decision tool for compensation of work-related musculoskeletal disorders.

We aimed to assess the predictivity of the biomechanical job-exposure matrix 'MADE' using compensation data from the National Health Insurance for work-related disorders. Data were obtained from 2013 to 2015, area under curves (AUC), sensitivity, specificity and predictive values were calculated using compensation results as reference. We collected 163 128 cases data. AUC ranged from 0.64 for shoulders disorder to 0.82 for knee disorders. If two thresholds were considered, 28.7% of the sample fit under or over those. The matrix showed a fair predictivity. Such matrix cannot replace expertise but might be a tool used for improving compensation process.

Transfer of the health care burden of occupational injuries and diseases from labor insurance to national health insurance in Taiwan.

BACKGROUND: Occupational injury and diseases result in substantial national health care burden. However, medical costs are often transferred to injured workers or the health insurance system. This study aims to examine the health care service utilization patterns of injured workers under the National Health Insurance (NHI) program in Taiwan and the barriers to medical benefit claims from labor insurance workers' compensation. METHODS: The total amount spent on medical benefits and national health expenditure from 1980 to 2014 was obtained. Workers who have experienced occupational injuries or diseases were identified in four waves of national surveys, and the types of medical care use were compared. In-depth interviews were conducted with 52 workers who had experienced occupational injuries and diseases. RESULTS: Since the implementation of the NHI program in 1995, medical benefits from workers' compensation have dropped substantially. In total, 75% of the workers who experienced occupational injuries or diseases had their medical costs covered through NHI. The time and effort costs caused by barriers against claiming medical benefits from workers' compensation decreased the incentive for workers from certain socioeconomic groups to make workers' compensation claims. CONCLUSION: Medical costs attributable to occupational injuries or diseases were mainly paid through NHI instead of through labor insurance. The economic burden was partially shifted from employers to workers, taxpayers, and the government.

Comparing disability and return to work outcomes between alternative and traditional workers' compensation programs.

BACKGROUND: The Union Construction Workers' Compensation Program (UCWCP) was developed in 1996 as an alternative workers' compensation arrangement. The program includes use of a preapproved medical and rehabilitation network and alternative dispute resolution (ADR), and prioritizes a quick and safe return-to-work. The aim of this study is to determine if differences in recovery-related outcomes exist between UCWCP and the statutory workers' compensation system (SWCS). METHODS: Claims data from 2003 to 2016 were classified as processed through UCWCP or SWCS. Outcomes included: temporary total disability (TTD), vocational rehabilitation (VR), claim duration and costs, and permanent partial disability (PPD). The relative risk of incurring TTD, VR, and PPD in UCWCP vs SWCS was calculated using log-binomial regression. Linear regression examined the relationship between programs and continuous outcomes including costs and duration. Estimates were adjusted for age, sex, wage, and severity. RESULTS: The UCWCP processed 15.8% of claims; higher percentages of UCWCP claimants were older and earned higher wages. Results point to positive findings of decreased TTD incidence and cost, lower risk of TTD extending over time, higher likelihood of VR participation, and less attorney involvement and stipulation agreements associated with UCWCP membership. Differences were more apparent in workers who suffered permanent physical impairment. CONCLUSION: Findings suggest that the defining programmatic elements of the UCWCP, including its medical provider and rehabilitation network and access to ADR, have been successful in their aims. Claims with increased severity exhibited more pronounced differences vs SWCS, potentially due, in part, to greater use of programmatic elements.

Work injuries in internal migrants to Alberta, Canada. Do workers' compensation records provide an unbiased estimate of risk?

INTRODUCTION: It is not known whether out-of-province Canadians, who travel to Alberta for work, are at increased risk of occupational injury. METHODS: Workers' compensation board (WCB) claims in 2013 to 2015 for those injured in Alberta were extracted by home province. Denominator data, from Statistics Canada, indicated the numbers from Alberta and Newfoundland and Labrador (NL) employed in Alberta in 2012. Both datasets were stratified by industry, age, and gender. Logistic regression estimated the risk of a worker from NL making a WCB claim in 2013 or 2014, stratified by time lost from work. Bias from under-reporting was examined in responses to injury questions in a cohort of trades' workers across Canada and in a pilot study in Fort McMurray, Alberta. RESULTS: Injury reporting rate in workers from NL was lower than those from Alberta, with a marked deficit (odds ratio [OR] = 0.17; 95% confidence interval [CI], 0.12-0.27) for injuries resulting in 1 to 30 days off work. Among the 1520 from Alberta in the trades' cohort, 327 participants reported 444 work injuries: 34.5% were reported to the WCB, rising to 69.4% in those treated by a physician. A total of 52 injuries in Alberta were recorded by 151 workers in the Fort McMurray cohort. In logistic regression, very similar factors predicted WCB reporting in the trades and Fort McMurray cohorts, but those from out-of-province or recently settled in Alberta were much less likely to report (OR = 0.02; 95% CI, 0.00-0.40). CONCLUSION: Differential rates of under-reporting explain in part the overall low estimates of injuries in interprovincial workers but not the deficit in time-loss 1 to 30 days.

Predictors of Return to Work for Occupational Rehabilitation Users in Work-Related Injury Insurance Claims: Insights from Mental Health.

Purpose This study evaluates the Occupational Rehabilitation (OR) initiatives regarding return to work (RTW) and sustaining at work following work-related injuries. This study also identifies the predictors and predicts the likelihoods of RTW and sustainability for OR users. Methods The study is conducted on the compensation claim data for people who are injured at work in the state of Victoria, Australia. The claims which commenced OR services between the first of July 2012 and the end of June 2015 are included. The claims which used original employer services (OES) have been separated from claims which used new employer services (NES). We investigated a range of predictors categorised into four groups as claimant, injury, and employment characteristics and claim management. The RTW and sustaining at work are outcomes of interest. To evaluate the predictors, we use Chi-squared test and logistic regression modelling. Also, we prioritized the predictors using Akaike Information Criterion (AIC) measure and Cross-validation error. Four predictive models are developed using significant predictors for OES and NES users to predict RTW and sustainability. We examined the multicollinearity of the developed models using Variance Inflation Factor (VIF). Results About 75% and 60% of OES users achieved RTW and have been sustained at work respectively, whilst just approximately 30% of NES users have been placed at a new employer and 25% of them have been sustained at work. The predictors which have the most association with OES and NES outcomes are the use of psychiatric services and age groups respectively. We found that having mental conditions is as an important indicator to allocate injured workers into OES or NES initiatives. Our study shows that injured workers with mental issues do not always have lower RTW rate. They just need special consideration. Conclusion Understanding the predictors of RTW and sustainability helps to develop interventions to ensure sustained RTW. This study will assist decision makers to improve design and implementation of OR services and tailor services according to clients' needs.

Work Disability in Australia: An Overview of Prevalence, Expenditure, Support Systems and Services.

Purpose This study sought to describe Australian systems of income support for people with work disability. Specific aims were to summarise and compare the features of the income support systems, including the rehabilitation and employment services funded or provided by those systems, and factors affecting transition between systems. Further objectives were to estimate the prevalence of work disability in Australia and the national expenditure on work disability income support. Methods A mixed methods project involving collation and analysis of existing publicly available documentation and data, and interviews with 25 experts across ten major systems of income support. The prevalence of work disability and expenditure in each system, and in total, was estimated using publicly accessible data sources. System features and service models were synthesised from data sources, tabulated and compared qualitatively. Results In Australia during the 2015/2016 financial year an estimated 786,000 people with work disability received income support from a Commonwealth, state, territory or private source. An additional 6.5 million people accessed employer provided leave entitlements for short periods of work incapacity. A total of $37.2 billion Australian dollars was spent on income support for these people during the year. This support was provided through a complex array of government authorities, private sector insurers and employers. Service models vary substantially between systems, with case management the only service provided across all systems. Healthcare and return to work services were provided in some systems, although models differed markedly between systems. Income support ranged from 19 to 100% of earnings for a person earning the average weekly Australian wage pre-disability. There is a paucity of information relating to movement between systems of support, however it is likely that many thousands of people with long periods of work disability transition between systems annually. Conclusions This study demonstrates the substantial financial and human impact of work disability on Australian society. Findings indicate multiple opportunities for reducing the burden of work disability, including aligning case management and healthcare service models, and engaging employers in prevention and rehabilitation. The findings suggest a need for greater interrogation and evaluation of Australian work disability support systems.

Impact of a Safe Resident Handling Program in Nursing Homes on Return-to-Work and Re-injury Outcomes Following Work Injury.

Purpose This study examined the impact of a Safe Resident Handling Program (SRHP) on length of disability and re-injury, following work-related injuries of nursing home workers. Resident handling-related injuries and back injuries were of particular interest. Methods A large national nursing home corporation introduced a SRHP followed by three years of training for 136 centers. Lost-time workers' compensation claims (3 years pre-SRHP and 6 years post-SRHP) were evaluated. For each claim, length of first episode of disability and recurrence of disabling injury were evaluated over time. Differences were assessed using Chi square analyses and a generalized linear model, and "avoided" costs were projected. Results The SRHP had no impact on length of disability, but did appear to significantly reduce the rate of recurrence among resident handling-related injuries. As indemnity and medical costs were three times higher for claimants with recurrent disabling injuries, the SRHP resulted in significant "avoided" costs due to "avoided" recurrence. Conclusions In addition to reducing overall injury rates, SRHPs appear to improve long-term return-to-work success by reducing the rate of recurrent disabling injuries resulting in work disability. In this study, the impact was sustained over years, even after a formal training and implementation program ended. Since back pain is inherently a recurrent condition, results suggest that SRHPs help workers remain at work and return-to-work.

Impact of an Advanced Imaging Utilization Review Program on Downstream Health Care Utilization and Costs for Low Back Pain.

BACKGROUND: Early magnetic resonance imaging (MRI) for acute low back pain (LBP) has been associated with increased costs, greater health care utilization, and longer disability duration in workers' compensation claimants. OBJECTIVES: To assess the impact of a state policy implemented in June 2010 that required prospective utilization review (UR) for early MRI among workers' compensation claimants with LBP. RESEARCH DESIGN: Interrupted time series. SUBJECTS: In total, 76,119 Washington State workers' compensation claimants with LBP between 2006 and 2014. MEASURES: Proportion of workers receiving imaging per month (MRI, computed tomography, radiographs) and lumbosacral injections and surgery; mean total health care costs per worker; mean duration of disability per worker. Measures were aggregated monthly and attributed to injury month. RESULTS: After accounting for secular trends, decreases in early MRI [level change: -5.27 (95% confidence interval, -4.22 to -6.31); trend change: -0.06 (-0.01 to -0.12)], any MRI [-4.34 (-3.01 to -5.67); -0.10 (-0.04 to -0.17)], and injection [trend change: -0.12 (-0.06 to -0.18)] utilization were associated with the policy. Radiograph utilization increased in parallel [level change: 2.46 (1.24-3.67)]. In addition, the policy resulted in significant decreasing changes in mean costs per claim, mean disability duration, and proportion of workers who received disability benefits. The policy had no effect on computed tomography or surgery utilization. CONCLUSIONS: The UR policy had discernable effects on health care utilization, costs, and disability. Integrating evidence-based guidelines with UR can improve quality of care and patient outcomes, while reducing use of low-value health services.

Tackling injustices of occupational lung disease acquired in South African mines: recent developments and ongoing challenges.

BACKGROUND: South Africa's mineral resources have produced, and continue to produce, enormous economic wealth; yet decades of colonialism, apartheid, capital flight, and challenges in the neoliberal post-apartheid era have resulted in high rates of occupational lung disease and low rates of compensation for ex-miners and their families. Given growing advocacy and activism of current and former mine workers, initiatives were launched by the South African government in 2012 to begin to address the legacy of injustice. This study aimed to assess developments over the last 5 years in providing compensation, quantify shortfalls and explore underlying challenges. METHODS: Using the database with compensable disease claims from over 200,000 miners, the medical assessment database of 400,000 health records and the employment database with 1.6 million miners, we calculated rates of claims, unpaid claims and shortfall in claim filing for each of the southern African countries with at least 25,000 miners who worked in South African mines, by disease type and gender. We also conducted interviews in Johannesburg, Eastern Cape, Lesotho and a local service unit near a mine site, supplemented by document review and auto-reflection, adopting the lens of a critical rights-based approach. RESULTS: By the end of 2017, 111,166 miners had received compensation (of which 55,864 were for permanent lung impairment, and another 52,473 for tuberculosis), however 107,714 compensable claims remained unpaid. Many (28.4%) compensable claims are from Mozambique, Lesotho, Swaziland, Botswana and elsewhere in southern Africa, a large proportion of which have been longstanding. A myriad of diverse systemic barriers persist, especially for workers and their families outside South Africa. Calculating predicted burden of occupational lung disease compared to compensable claims paid suggests a major shortfall in filing claims in addition to the large burden of still unpaid claims. CONCLUSION: Despite progress made, our analysis reveals ongoing complex barriers and illustrates that the considerable underfunding of the systems required for sustained prevention and social protection (including compensation) needs urgent attention. With class action suits in the process of settlement, the globalized mining sector is now beginning to be held accountable. A critical rights-based approach underlines the importance of ongoing concerted action by all.

Medical Care Spending and Labor Market Outcomes: Evidence from Workers' Compensation Reforms.

Medical care represents an important component of workers' compensation benefits with the potential to improve health and post-injury labor outcomes, but little is known about the relationship between medical care spending and the labor outcomes of injured workers. We exploit the 2003--2004 California workers' compensation reforms which reduced medical spending disproportionately for workers incurring low back injuries. We link administrative claims data to earnings records for injured workers and their uninjured coworkers. We find that workers with low back injuries experienced a 7.6 percent post-reform decline in medical care, and an 8.1 percent drop in post-injury earnings relative to other injured workers.

Effectiveness of employer financial incentives in reducing time to report worker injury: an interrupted time series study of two Australian workers' compensation jurisdictions.

BACKGROUND: Early intervention following occupational injury can improve health outcomes and reduce the duration and cost of workers' compensation claims. Financial early reporting incentives (ERIs) for employers may shorten the time between injury and access to compensation benefits and services. We examined ERI effect on time spent in the claim lodgement process in two Australian states: South Australia (SA), which introduced them in January 2009, and Tasmania (TAS), which introduced them in July 2010. METHODS: Using administrative records of 1.47 million claims lodged between July 2006 and June 2012, we conducted an interrupted time series study of ERI impact on monthly median days in the claim lodgement process. Time periods included claim reporting, insurer decision, and total time. The 18-month gap in implementation between the states allowed for a multiple baseline design. In SA, we analysed periods within claim reporting: worker and employer reporting times (similar data were not available in TAS). To account for external threats to validity, we examined impact in reference to a comparator of other Australian workers' compensation jurisdictions. RESULTS: Total time in the process did not immediately change, though trend significantly decreased in both jurisdictions (SA: -0.36 days per month, 95% CI -0.63 to -0.09; TAS: 0.35, -0.50 to -0.20). Claim reporting time also decreased in both (SA: -1.6 days, -2.4 to -0.8; TAS: -5.4, -7.4 to -3.3). In TAS, there was a significant increase in insurer decision time (4.6, 3.9 to 5.4) and a similar but non-significant pattern in SA. In SA, worker reporting time significantly decreased (-4.7, -5.8 to -3.5), but employer reporting time did not (-0.3, -0.8 to 0.2). CONCLUSIONS: The results suggest that ERIs reduced claim lodgement time and, in the long-term, reduced total time in the claim lodgement process. However, only worker reporting time significantly decreased in SA, indicating that ERIs may not have shortened the process through the intended target of employer reporting time. Lack of similar data in Tasmania limited our ability to determine whether this was a result of ERIs or another component of the legislative changes. Further, increases in insurer decision time highlight possible unintended negative effects.

Age, sex, and the changing disability burden of compensated work-related musculoskeletal disorders in Canada and Australia.

BACKGROUND: The objectives of this study were (1) to identify age and sex trends in the disability burden of compensated work-related musculoskeletal disorders (MSDs) in Canada and Australia; and (2) to demonstrate a means of comparing workers' compensation data internationally. METHODS: All non-fatal, work-related MSD claims with at least one day of compensated time-loss were extracted for workers aged 15-80 during a 10-year period (2004-2013) using workers' compensation data from five Canadian and eight Australian jurisdictions. Disability burden was calculated for both countries by sex, age group, and injury classification, using cumulative compensated time-loss payments of up to two years post-injury. RESULTS: A total of 1.2 million MSD claims were compensated for time-loss in the Canadian and Australian jurisdictions during 2004-2013. This resulted in time-loss equivalent to 239,345 years in the Canadian jurisdictions and 321,488 years in the Australian jurisdictions. The number of time-loss years declined overall among male and female workers, but greater declines were observed for males and younger workers. The proportion of the disability burden grew among older workers (aged 55+), particularly males in the Canadian jurisdictions (Annual Percent Change [APC]: 7.2, 95% CI 6.7 to 7.7%) and females in the Australian jurisdictions (APC: 7.5, 95% CI 6.2 to 8.9%). CONCLUSIONS: The compensated disability burden of work-related MSDs is shifting towards older workers and particularly older females in Australia and older males in Canada. Employers and workers' compensation boards should consider the specific needs of older workers to reduce injuries and time off work. Comparative research made possible through research-stakeholder partnerships offers a unique opportunity to use existing administrative data to identify long-term trends in disability burden. Future research can apply similar approaches for estimating long-term trends in occupational health.
