Incidence, trends and factors associated with psychological injury among health and social care workers in New South Wales, Australia: a retrospective cohort study of workers' compensation claims.

OBJECTIVES: To describe and compare the incidence and trends of workers' compensation (WC) claims for psychological injury: (1) between health and social care (HSC) industry and other industries; (2) among specific occupations in the HSC industry; and (3) to determine if psychological injury claim rates differ by age and gender in the HSC industry and among specific occupations. METHODS: A retrospective cohort study was conducted using data from the New South Wales WC system. Workers with accepted psychological injury claims between July 2012 and June 2021 were included. Negative binomial regression models were employed to estimate incidence rate ratios and 95% CIs. RESULTS: The HSC industry had a higher incidence (2.4 per 1000 workers) than all other industries combined (1.1 per 1000 workers). In the HSC industry, the incidence increased from 1.8 in 2013-2015 to 3.4 in 2019-2021. Ambulance officers had the highest incidence (24.9 per 1000 workers) and the highest growth rate. Nurses and midwives, and aged and disability care workers also had fast-growing incidence over the 9 years. Risk of psychological injury claims was highest among female workers and older adults. CONCLUSIONS: The increasing incidence and trend of psychological injury claims among HSC workers in New South Wales signify a growing public health issue. Greater efforts are needed to prevent work-related psychological injury in the HSC industry and support affected workers. The different patterns of psychological injury claims across occupations suggest that interventions should be tailored to each occupational group.

Time off work following psychological injury among health and social care workers: a population-based retrospective cohort study in New South Wales, Australia.

OBJECTIVE: This study aimed to determine the disability duration and burden of compensated time loss in the health and social care (HSC) sector following psychological injury. METHODS: A retrospective cohort study was conducted using data from the New South Wales workers' compensation system. The median weeks disability duration and total weeks of working time lost (WWL) per 1000 workers were compared between the HSC sector and all other industries, and between specific occupational groups in the HSC sector, using accelerated failure time models. RESULTS: HSC workers had a median (IQR) disability duration of 12.4 (3.3-40.0) weeks, which was less than the 15.3 (4.3-48.3) weeks observed in other industries. Within the HSC sector, ambulance officers had the longest disability duration at 31.1 (6.1-104.0) weeks and highest WWL at 15 734 weeks per 1000 workers. Conversely, nurses and midwives had the shortest disability duration at 8.0 (2.0-25.8) weeks, while other healthcare workers had the lowest WWL (17.0). Controlling for other determinants, ambulance officers had the highest likelihood of longer disability duration (time ratio (TR) 2.14; 95% CI 1.64 to 2.78), followed by social workers (TR 1.46; 95% CI 1.20 to 1.79) and administrators and managers (TR 1.41; 95% CI 1.15 to 1.71). Older age, female sex, full-time employment and working in small organisations correlated with extended disability duration. CONCLUSION: There is considerable variation in the duration and burden of work disability due to psychological injury across occupational groups in the HSC sector. Findings suggest the need for occupation-specific workplace rehabilitation and psychological support to reduce the impact of psychological injury on HSC workers and improve return-to-work outcomes.

The relationship between work disability and subsequent suicide or self-harm: A scoping review.

Work disability occurs when an injury or illness limits the ability of a worker to participate in employment. While evidence suggests that people with work disability are at increased risk of suicide and intentional self-harm, this relationship has not been the subject of systematic review. This scoping review aims to assess and summarise the research literature regarding the relationship between work disability and subsequent suicide or intentional self-harm. Review protocol was published on the Open Science Foundation and is reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Peer-reviewed studies published in English from 1st January 2000 were included if they reported suicide or self-harm outcomes in people aged 15 years or older with work disability. Studies were identified via systematic search of Medline, Scopus and Pubmed databases, via recommendation from topic experts, and citation searching of included articles. A narrative synthesis was undertaken. Literature search yielded 859 records of which 47 eligible studies were included, nine set in workers' compensation, 20 in sickness absence, 13 in disability pension systems, and five from mixed cohorts. Of 44 quantitative studies, 41 reported a positive relationship between work disability and suicidal behaviour. The relationship is observed consistently across nations, work disability income support systems and health conditions. Several factors elevate risk of suicidal behaviour, including presence of mental health conditions and longer work disability duration. There were few studies in some nations and no suicide prevention interventions. The risk of suicide and self-harm is elevated in people experiencing work disability. Further observational research is required to fill evidence gaps. This review suggests the need for governments, employers and those involved in the care of people with work disability to focus on identification and monitoring of those at greatest risk of suicidal behaviour, and suicide prevention.

Impact of legislative reform on benefit access and disability duration in workers' compensation: an interrupted time series study.

OBJECTIVES: To determine the impact of legislative changes to the New South Wales (NSW) workers' compensation scheme on injured workers access to benefits, insurer claim processing and work disability duration. METHODS: Population-based interrupted time series study of workers' compensation claims made in NSW 2 years before and after legislative amendment in June 2012. Outcomes included incidence of accepted claims per 100 000 workers, the median and 75th percentile insurer decision time in days, and the median and 75th percentile of work disability duration in weeks. Effects were assessed relative to a comparator of seven other Australian workers' compensation jurisdictions. RESULTS: n=1 069 231 accepted workers' compensation claims were analysed. Claiming in NSW fell 15.3% following legislative reform, equivalent to 46.6 fewer claims per 100 000 covered workers per month. This effect was greater in time loss claims (17.3%) than medical-only claims (10.3%). Across models, there were consistent trend increases in insurer decision time. Median work disability duration increased following the legislative reform. CONCLUSIONS: The observed reduction in access to benefits was consistent with the policy objective of improving the financial sustainability of the compensation scheme. However, this was accompanied by changes in other markers of performance that were unintended, and are suggestive of adverse health consequences of the reform. This study demonstrates the need for care in reform of workers' compensation scheme policy.

Work absence due to compensable RTCs in Victoria, Australia.

INTRODUCTION: RTC burden is commonly measured using fatality or hospitalisation statistics. However, non-fatal and less severe injuries contribute substantial economic and human costs, including work absence. In Victoria, Australia, two major compensation systems provide income support to employed people injured in RTCs; workers' compensation (if RTC occurred during work) and an RTC-specific compensation system. This study aimed to describe the number and rate of episodes of work absence due to compensable RTC and determine factors associated with work-related RTC resulting in work absence. METHODS: Administrative data for working-age people (15-65 years) with accepted compensation claims between 1 July 2003 and 30 June 2013 were extracted from Victoria's Compensation Research Database and analysed. Injured people receiving at least one day of income support were retained. Rate calculations used Victoria's labour force as the denominator and negative binomial regression determined any time-based trend changes. Multivariable logistic regression was used to determine odds of the RTC being work-related. RESULTS: There were 40 677 claims made by workers with an RTC injury that consequently missed work, averaging 4068 claims per year at a rate of 12.9 per 100 000 working population. Work-related cases contributed 17.4% (N=7061). Males, older adults and RTCs involving heavy vehicles, buses, trains and trams had higher odds of a work-related RTC resulting in work absence. More severe injuries tended not to be work-related. CONCLUSIONS: Work absence due to RTC injury constitutes a substantial burden, and this measure could provide a valuable addition to conventional RTC statistics.
