Workers' disability and return to work.

A severe injury on the job often results in a medical recovery period requiring either a temporary or long-term absence from work. Rehabilitation interventions emphasizing return to work may facilitate recovery and prevent workers from becoming unemployed. A review of the current literature suggests a direct relationship between workers' demographic and disability-related characteristics, early referral to rehabilitation and successful return to work. This article describes findings from a research study designed to investigate factors associated with the return to work of injured workers. Data from 200 workers' compensation cases from a large automobile manufacturing employer in the state of Michigan were analyzed in terms of workers' demographics and other characteristics including type and severity of injury, cause of injury, type of medical intervention received, disability status, worker's job experience and wages before injury; disability costs to employer; the provision of vocational rehabilitation services; and return-to-work outcomes. Variables found to be significantly related to return to work outcomes included workers' age, education, wages before injury, job seniority and severity of the injury. Workers who successfully returned to work had higher seniority in their jobs, more education and were paid higher wages. Workers whose injuries were more severe and longer lasting, were less likely to return to work. Back impairments appeared to be a particular risk factor for return to work regardless of vocational rehabilitation intervention.
