1176 FATIGUE RISK MANAGEMENT PROGRAM INCREASES SLEEP AND ALERTNESS IN FIREFIGHTERS

Abstract

Introduction: Firefighters work challenging schedules under highly stressful and demanding conditions. Extended‐duration (greater than or equal to 24h) work shifts are common. Obtaining adequate sleep and maintaining alertness throughout overnight shifts is challenging. We conducted a station‐level, randomized trial of a fatigue risk management program (FRMP) in an urban fire department which included policies designed to maximize sleep opportunities. Methods: Thirty‐four fire stations, including more than 500 firefighters, were paired and one station from each pair randomized to receive the FRMP intervention. Sleep health education and screening for common sleep disorders was provided for firefighters assigned to FRMP fire stations. Additionally, FRMP stations were outfitted with blackout shades for windows in sleep quarters and a policy to permit and encourage napping during the late afternoon, if not required to work, was instituted. Control and FRMP firefighters completed baseline and follow‐up surveys approximately one year later. Results: More than three‐quarters of firefighters assigned to a FRMP station reported sleeping in a room where the blackout shades were installed. Whereas 63.5% of firefighters reported that light negatively impacted their sleep on the baseline survey, 81% of those firefighters reported that the blackout shades improved their sleep. Additionally, 79% of firefighters in the FRMP group reported taking advantage of the rest policy. Firefighters in the FRMP group reported significantly improved sleep quality as compared to firefighters in the control group (p<0.001). Only 23% of firefighters in the control group reported increasing their sleep duration overall. In the FRMP group, 49% of firefighters reported increased sleep at the fire station. At follow‐up, firefighters in the FRMP group reported feeling less sleepy (p<0.001). Firefighters in the FRMP group reported that the FRMP was important and helpful and they recommended it to other fire departments. Conclusion: This project provides evidence for improved sleep associated with a fatigue risk management program. Sleep management approaches that are practical and readily deployable in occupational settings should be rapidly expanded.
