RESUMO
OBJECTIVES: Injuries at work are common and costly for individuals and employers. A common mechanism of workplace injury is through falls, but there have been few epidemiological studies of risk factors. This study aimed to identify patient, work and injury factors associated with injuries causing hospitalisation after falling at work in Victoria, Australia. METHODS: Data came from work-related hospitalised injury admissions, identified by International Classification of Diseases and Related Health Problems, Tenth Revision Australian Modification codes and compensation status, from Victorian Admitted Episodes Dataset between 1 July 2017 and 30 June 2022. Multivariate logistic regression analyses were conducted to identify factors associated with same-level falls and falls from height. RESULTS: This study included 42 176 work-related injury admissions: 8669 (20.6%) fall injuries and 33 507 (79.4%) other injuries. Rates of high falls were more common in males than females (0.44 (95% CI: 0.43, 0.46) vs 0.08 (0.08, 0.09) admissions per 1000 employed), while same-level falls were more common in females than males (0.21 (0.20, 0.22) vs 0.18 (0.17, 0.18)). Patients with same-level fall injuries, relative to all other work injuries, were more likely to be older women, and have at least one chronic condition; falls from height were associated with male sex and construction work and more likely to result in intracranial, internal organ injuries and fractures and longer hospital stay than non-fall injuries. CONCLUSION: Work-related falls were common and relatively severe. Same-level falls are relatively likely to occur in older women, the fastest-growing workplace demographic, and therefore the incidence is expected to increase. Comorbidities are an important fall risk factor. Employers could consider industry-relevant high and same-level fall prevention strategies for reducing the workplace injury burden.

OBJECTIVES: Hospital attendance related to fire, flame or smoke exposure is commonly associated with work. The aim of this study was to examine time trends and risk factors for work-related fire/flame/smoke injuries in Victoria, Australia. METHODS: This study was based on emergency department (ED) presentation records from the Victorian Emergency Minimum Dataset, 2003-2021. Cases were people aged 15-74 years with injury-related ED presentations, if cause of injury was recorded as fire/flame/smoke, based on coded data and/or narratives. Work-related rates were calculated per employed persons; non-work rates were calculated per population. Work-related and non-work-related cases were compared using logistic regression modelling. RESULTS: There were 11 838 ED presentations related to fire/flame/smoke: 1864 (15.7%) were work-related. Non-work-related rates were 12.3 ED presentations per 100 000 population, and work-related rates were 3.43 per 100 000 employed persons annually. Over the study period, work-related rates decreased annually by 2.0% (p<0.0001), while non-work rates increased by 1.1% (p<0.0001). Work-related cases (vs non-work) were associated with summer (vs winter), but the association with extreme bushfire periods (Victorian 'Black Saturday' and 'Black Summer') was not statistically significant. Work-related cases were less severe than non-work-related cases, evidenced by triage status and subsequent admission. CONCLUSIONS: Rates of occupational fire/flame/smoke-related injury presentations decreased over the past two decades in Victoria, while non-work-related rates increased. This could reflect improved safety in the workplace. Hospital data, however, cannot be used to distinguish occupation or industry therefore, employment data linkage studies are recommended to further inform workplace preventive measures.

OBJECTIVES: Autoimmune disorders are multifactorial but occupational exposures have long been implicated, including respirable crystalline silica (RCS). A modern epidemic of silicosis is emerging internationally, associated with dry processing of engineered stone with high (>90%) RCS content. We aimed to investigate the prevalence of clinical autoimmune disease and common autoantibodies in exposed workers. METHODS: Stone benchtop industry workers in Victoria, Australia were offered free screening for silicosis and related disorders. Symptoms or diagnoses of autoimmune disease were evaluated by questionnaire and blood tests taken for rheumatoid factor (RF), antinuclear antibodies (ANAs) and extractable nuclear antigens (ENAs). RESULTS: Among 1238 workers (93.3% male) screened from 2019 to 2021, 0.9% were confirmed with autoimmune disease. Among those without clinical disease, 24.6% had detectable ANAs (93.5% male), 4.6% detectable ENAs and 2.6% were positive for RF. Silicosis was diagnosed in 253 workers (24.3% of those with diagnostic information available). Of those with ANA readings, 54 (6.6%) had ANA titre >1:320. The likelihood of positive autoantibodies increased with age; smoking; higher exposure to RCS and silicosis diagnosis. CONCLUSION: The proportion of workers with detectable ANAs or ENAs was considerably higher than the 5%-9% expected in the general population. Some of the antibodies detected (eg, Scl-70, CENPB) have high sensitivity and specificity for systemic sclerosis. Long-term follow-up will be needed to estimate incidence. Rheumatologists should explore occupational history in new cases of autoimmune disease. Screening for autoimmune disease is indicated in workers exposed to RCS as these individuals need specialised management and may be entitled to compensation.
RESUMO
BACKGROUND: The Perceived Stress Scale (PSS-10) has been used in a range of occupational cohorts, but only recently in stone benchtop workers undergoing screening for silicosis. The aim of this study was to compare psychometric properties of the PSS-10 in stone benchtop workers amongst those born overseas or who used an interpreter. METHODS: Stone benchtop workers in Melbourne, Australia completed the PSS-10 as part of their occupational screening for silicosis. Internal consistency was assessed with Cronbach's α for the total score and the positive and negative subscales. Validity was assessed using confirmatory factor analysis (CFA). Analysis was performed for the total group and for subgroups according to sex, interpreter use, overseas-born, and language spoken at home. RESULTS: The results of 682 workers with complete PSS-10 scores were included in analysis. Most participants were male (93%), with mean age 36.9 years (SD 11.4), with just over half (51.6%) born in Australia, 10.1% using an interpreter, and 17.5% using a language other than English at home. Cronbach's α for the overall group (α = 0.878) suggested good internal consistency. DISCUSSION: CFA analysis for validity testing suggested PSS-10 performance was good for both sexes, moderate for country of birth and language spoken at home categories, but poorer for those who used an interpreter. Whilst professional interpreters provide a range of benefits in the clinical setting, the use of translated and validated instruments are important, particularly in cohorts with large numbers of migrant workers. CONCLUSION: This study describes the psychometric properties of the PSS-10 in a population of stone benchtop workers, with good internal consistency, and mixed performance from validity testing across various subgroups.

BACKGROUND AND OBJECTIVE: Chest x-ray (CXR) remains a core component of health monitoring guidelines for workers at risk of exposure to crystalline silica. There has however been a lack of evidence regarding the sensitivity of CXR to detect silicosis in artificial stone benchtop industry workers. METHODS: Paired CXR and high-resolution computed tomography (HRCT) images were acquired from 110 artificial stone benchtop industry workers. Blinded to the clinical diagnosis, each CXR and HRCT was independently read by two thoracic radiologists from a panel of seven, in accordance with International Labour Office (ILO) methodology for CXR and International Classification of HRCT for Occupational and Environmental Respiratory Diseases. Accuracy of screening positive (ILO major category 1, 2 or 3) and negative (ILO major category 0) CXRs were compared with identification of radiological features of silicosis on HRCT. RESULTS: CXR was positive for silicosis in 27/110 (24.5%) workers and HRCT in 40/110 (36.4%). Of the 83 with a negative CXR (ILO category 0), 15 (18.1%) had silicosis on HRCT. All 11 workers with ILO category 2 or 3 CXRs had silicosis on HRCT. In 99 workers ILO category 0 or 1 CXRs, the sensitivity of screening positive CXR compared to silicosis identified by HRCT was 48% (95%CI 29-68) and specificity 97% (90-100). CONCLUSION: Compared to HRCT, sensitivity of CXR was low but specificity was high. Reliance on CXR for health monitoring would provide false reassurance for many workers, delay management and underestimate the prevalence of silicosis in the artificial stone benchtop industry.

BACKGROUND: Governments of Western countries need people to work to older ages, however the COVID-19 pandemic impacted the workforce by pushing older adults to retire. Socio-demographic factors that influence the decision to retire in the pre-pandemic period were, poor or good health, finances, marital status, and gender. The aim of this study was to explore aspects that contributed to the decision to retire among middle-aged and older people in England who retired during the COVID-19 pandemic. METHODS: In September 2022 semi-structured interviews were conducted with a sample of participants from the Health and Employment After Fifty (HEAF) study who retired since March 2020. Consenting participants were purposively selected to achieve a wide spread of characteristics deemed important in the retirement process. Telephone interviews were conducted, audio-recorded, transcribed and then thematically analysed. RESULTS: 24 interviews were conducted (10 men and 14 women, mean age 65 years). Six themes were identified: four of them were non-COVID-19 aspects while two can be interpreted as impact of COVID-19 on the workforce. Work-related factors were of major importance. A sense of appreciation and attachment in relation to their employer, and conversely high work demands and stress, as well as changes in work responsibilities and work practices since lockdown and/or perception of personal safety in the workplace during the pandemic influenced their retirement decision, as did physical and mental health issues. Another theme suggested that some participants felt they had reached the 'right' age and needed to spend more time with family. Having the financial capacity to retire was widely mentioned but was never the main factor. CONCLUSIONS: The decision to retire during the pandemic was multi-factorial although changes to work during lockdown were of great importance. Post-pandemic, our findings suggest that there are modifiable aspects of work, including appreciation and fair pay and work conditions, that employers and policy makers could encourage to retain their older workers.

BACKGROUND AND PURPOSE: Younger recipients of total hip arthroplasty (THA) highly prioritize returning to preoperative levels of physical activity (PA). Surgeons have tended to give cautious advice concerning high-impact sports participation, but there have been few long-term studies. The purpose of our study was to investigate the risk of revision arthroplasty in relation to postoperative PA levels. METHODS: Patients registered in the Geneva Arthroplasty Register (GAR) who had elective THA when they were aged < 65 years were studied. Postoperative PA was collected prospectively 5-yearly using the UCLA activity scale. Cox proportional hazards models were used to estimate associations between PA and risk of revision THA. RESULTS: Amongst 1,370 eligible subjects, median age at THA 58 years (interquartile range 51-61), UCLA scores were available for 973 (71%). During follow-up over 15 years, there were 79 revisions, giving a cumulative risk of 7.4% (95% confidence interval [CI] 5.8-9.4). After adjusting for covariates, we found an increased risk of revision for each unit increase in postoperative PA (HR 1.2, CI 1.1-1.4), and among people performing the most intensive PA (HR 2.7, CI 1.3-5.6) compared with those who were inactive. CONCLUSION: The overall risk of revision was small but intensive and moderate PA may be associated with an increased risk of revision.

INTRODUCTION: With demographic changes, there is increasing demand for individuals and governments to lengthen working lives. Jobs that are very physically demanding are likely to be more difficult to sustain at older ages. If workers at risk of mismatch of demand and capability could be identified early, there would be opportunities for intervention for health or lifestyle and/or re-training or redeployment. OBJECTIVE: To investigate whether self-reported walking speed (a good measure of function in elderly people) predicted health-related job loss (HRJL) longitudinally over 5 years of follow-up among middle-aged workers. DESIGN: Data came from the Health and Employment After Fifty (HEAF) prospective cohort study of middle-aged people (aged 50-64 years) in UK. SETTING: General population survey (sampling frame was 24 General Practice registers). PARTICIPANTS: The cohort included 8134 people recruited in 2013-2014. For the current analyses, 5217 people who ever worked and completed at least one follow-up questionnaire were eligible. PRIMARY OUTCOME: Exit from employment mainly or partly for health reasons (HRJL). RESULTS: At baseline, very slow walking speed was associated with: obesity, physical inactivity, smoking (men), financial hardship, lower educational attainment and not being in professional occupations. In total, 527 people (10%) reported at least one HRJL during follow-up. After adjustment, the HR for HRJL among men with very slow walking-speed was 4.32, 95% CI 2.72 to 6.87 and among women was 4.47, 95% CI 3.04 to 6.57. After further adjustment for 'difficulty coping with physical demands at work', hazards remained doubled in men and women. CONCLUSIONS: Self-reported walking speed could help identify older workers who are at increased risk of HRJL. This could provide opportunities for intervention through optimising health and lifestyle, restricting physical workload, retraining or redeployment. Early appropriate intervention could enable longer working lives and promote healthier, more equal ageing.

Background: Certain occupational characteristics have been linked with poor health and reduced longevity. However, the association between occupational characteristics and survival free of disability in a post-retirement age group has not been investigated. Methods: We investigated outcomes in 12,215 healthy older Australian adults in the Aspirin in Reducing Events in the Elderly (ASPREE) and ASPREE Longitudinal Study of Older Persons (ALSOP) sub-study. The ISCO-88 major occupational groups, settings, and activity levels were assigned based on free-text job descriptions. The Finnish Job Exposure Matrix was used to assign occupational characteristics to the three longest-held jobs. The primary endpoint, disability-free survival, was defined as a composite measure of death, dementia, or persistent physical disability. The endpoint of all-cause mortality was analyzed separately. Because of multiple exploratory analyses, only those associations with a two-sided value of p less than 0.005 were considered statistically significant. Cox proportional hazard models were used to calculate adjusted hazard ratios. Results: Having worked in an 'elementary' occupation was associated with a reduction in disability-free survival. A specific impact on disability-free survival was observed among those whose work had involved high accident risk and adverse social climate. No significant relationship was identified with those previously exposed to sedentary work, vigorous physical activity, work primarily outdoors, or a range of other occupational characteristics. All-cause mortality was not increased among any of the occupational groups. Conclusion: This exploratory study found a reduction in disability-free survival among people who worked in 'elementary' occupations, with specific risks associated with occupations involving high accident risks and adverse social climate.
