To identify predictors of return to work, duration of time off work, and claim closure for first responders experiencing injuries or illnesses, and summarize the claim data. Methods: First responder claims collected between January 2012 and July 2017 were obtained from a disability management company. Known predictors of return to work were extracted from the data including age, sex, diagnosis, years of service, claim lag, medical report lag, and the return-to-work duties. Survival analyses were performed to identify predictors of return to work and claim closure using the Cox proportional regression analysis. Log-rank tests were performed to identify predictors that affected the rate of return to work and claim closure. Summary statistics were performed for the injury and return-to-work data.
