Traditional analyses of the impact of work-related injuries have focused on numbers and rates (per 100,000 employed) of injuries and, occasionally, tabulations of injury costs from workers compensation data. This study combines workers, compensation data with actual work hours data (from payroll records) and survey data. In order to develop an additional metric for analysis, work-related injury costs were calculated as number of dollars in workers compensation per 100 work-hours and modeled using a generalized linear model. Gamma regression was used to explore the associations between work-related injury cost rates and individual employee risk factors, taking account of the exposure variable of workhours for each employee. This study makes use of data from a large NIOSH study in which a prospective cohort of 9,377 material handling employees was observed for up to two years from 1996 to 1998. All types of work-related injuries were included. The injury costs include medical and indemnity payments. The 9,377 workers contributed 22.2 million work-hours. There were 2,065 injury claims with a total of $2.l million in payments. For the study population the average work-related injury cost rate was $9.48/100 work-hours. The risk factors that were found to be significantly associated with the cost rate were history of previous back injury, age group, job title, smoking, and back belt wearing. Analysis of cost per hours of work adds another dimension to analysis of work-related injuries and in combination with survey data, allows assessment of individual characteristics and risk factors in relationship to work-related injuries. Targeting of research prevention strategies may be enhanced with these additional analyses.
