The development of a conceptual model and self-reported measure of occupational health and safety vulnerability.

Injuries at work have a substantial economic and societal burden. Often groups of labour market participants, such as young workers, recent immigrants or temporary workers are labelled as being "vulnerable" to work injury. However, defining groups in this way does little to enable a better understanding of the broader factors that place workers at increased risk of injury. In this paper we describe the development of a new measure of occupational health and safety (OH&S) vulnerability. The purpose of this measure was to allow the identification of workers at increased risk of injury, and to enable the monitoring and surveillance of OH&S vulnerability in the labour market. The development included a systematic literature search, and conducting focus groups with a variety of stakeholder groups, to generate a pool of potential items, followed by a series of steps to reduce these items to a more manageable pool. The final measure is 29-item instrument that captures information on four related, but distinct dimensions, thought to be associated with increased risk of injury. These dimensions are: hazard exposure; occupational health and safety policies and procedures; OH&S awareness; and empowerment to participate in injury prevention. In a large sample of employees in Ontario and British Columbia the final measure displayed minimal missing responses, reasonably good distributions across response categories, and strong factorial validity. This new measure of OH&S vulnerability can identify workers who are at risk of injury and provide information on the dimensions of work that may increase this risk. This measurement could be undertaken at one point in time to compare vulnerability across groups, or be undertaken at multiple time points to examine changes in dimensions of OH&S vulnerability, for example, in response to a primary prevention intervention.

Occupational injury risk among ambulance officers and paramedics compared with other healthcare workers in Victoria, Australia: analysis of workers' compensation claims from 2003 to 2012.

OBJECTIVE: To investigate occupational risk of musculoskeletal (MSK) and mental injury among ambulance officers and paramedics, and compare with nurse professionals, social and welfare professionals, and carers and aides in Victoria, Australia, using workers' compensation (WC) claims statistics. METHODS: Data were retrieved from the Victorian Compensation Research Database (CRD). Analysis was restricted to claims received between 1 July 2003 and 30 June 2012. WC claim rates were calculated using labour force statistics, and expressed per 1000 full-time equivalent workers. Adjusted HRs with 95% CIs for injury risk were estimated using multivariable regression modelling. RESULTS: Ambulance officers and paramedics had an upward trend in WC claim rates for all injuries and the highest rates for MSK and mental injury, in comparison with other healthcare workers during the study period. In the 2009-2012 time period, ambulance officers and paramedics' risk of lower back MSK and mental injury was approximately 13 times higher than nurse professionals, HRs 57.6 vs 4.4 and 17.77 vs 1.29, respectively. Social and welfare professionals had the second highest risk of mental injury, which was up to threefold greater than in nurses. Carers and aides and nurse professionals had similar HRs overall for all injury categories. CONCLUSIONS: Differential patterns of MSK and mental injury exist among healthcare occupational groups in Victoria, Australia. Given the significant findings, especially the high risks among ambulance personnel, future research should focus on the circumstances of injury to improve understanding and inform prevention programmes.
