Incidence and risk of work-related fracture injuries: experience of a state-managed workers' compensation system.
Incidence rates of occupational fractures at various anatomic sites and associated risk factors have not been well documented. We identified 3490 work-related fractures from a West Virginia Workers Compensation database that occurred between July 1, 1994, and June 30, 1995. The annual incidence rate was 55 per 10,000 workers, which is substantially higher than the work-related fracture rates reported previously. The incidence rate of fracture was highest in the agricultural sector, followed by the mining, construction, and manufacturing sectors (202.0, 165.2, 116.7, and 88.0 per 10,000 workers, respectively). The age-specific gender distribution comparing fracture and non-fracture injuries showed a bimodal distribution, with greater proportions of female employees at the younger and older age groups. Fracture of the phalanges was the most common, followed by fractures of the foot bone and carpal bone (15.8, 9.5, and 7.9 per 10,000 workers, respectively). In a multiple logistic regression analysis, age, gender, occupation, caught in-between objects, fall, struck by or against object, and vehicle collision were significant independent predictors of fracture (all sites combined). We believe work-related fractures to be a bigger problem than previously reported. The association among gender, age, occupation, and causes of fractures identified in this study will be useful in developing gender- and occupation-specific prevention intervention.
