Influence of workers' compensation eligibility upon functional recovery 10 to 28 years after polytrauma

Background: Previous studies have shown that work-related injuries are often associated with inferior outcomes. The aim of the current study was to compare the long-term functional outcome after polytrauma between work-related and non-work-related injuries at a minimum follow-up of 10 years. Methods: Six hundred thirty-seven polytrauma patients were evaluated using a patient questionnaire and a physical examination. The average follow-up was 17.5 years (range 10-28 years); the average Injury Severity Score (ISS) was 20.7 (range 4 to 54). Results: A multivariate analysis, with adjustments for age, sex, injury severity, and injury pattern, demonstrated that work-related injuries resulted in significantly inferior outcomes measured by the Hannove Score for Polytrauma Outcome (HASPOC), 12-Item Short-Form Health Survey (SF-12), requirement for medical aids and devices, length of rehabilitation, and retirement status (P < .05). Conclusions: Polytrauma patients receiving workers' compensation achieve significantly inferior long-term outcomes than other patients. The obtained results demonstrate that psychosocial variables such as insurance status have a significant impact on the functional recovery following polytrauma.
