Summary

Firefighters frequently work extended duration shifts and long work weeks which have adverse effects on alertness, health, safety and performance. This protocol uses a survey instrument to examine the effects of extended duration shifts on safety outcomes (e.g., motor vehicle crashes, accidents, injuries), health (e.g., diagnosis and treatment of sleep disorders, improved general health indices, decreased number of sick days), and performance (e.g., decreased response time). This study will expand understanding of the nature, scope, etiology and consequences of firefighter fatigue and increase our ability to develop guidelines that can be generalized across fire departments throughout North America. This study could provide an avenue to make lasting policy improvements that could enhance the safety, health, and performance of firefighters.

Detailed description

Firefighters work some of the most challenging schedules known under highly stressful and demanding conditions. The need to work frequent extended shifts leads to acute and chronic sleep deficiency as well as disruption of circadian rhythms. Firefighters on-call overnight are also particularly susceptible to sleep inertia, the neurocognitive impairment experienced immediately upon waking. In addition, it is likely that a significant proportion of firefighters suffer from undiagnosed sleep disorders, which further impair sleep and exacerbate fatigue. The proposed fatigue countermeasure aims to increase sleep opportunities, and thereby improve firefighter safety and health. We will be conducting a station-level, randomized clinical trial of policies designed to maximize sleep opportunities during current 24-hour shifts to improve alertness, performance, health and safety in firefighters. We will leverage the comprehensive fatigue management program we developed and the web-based technology we implemented in previous Federal Emergency Management Agency projects, and will continue to offer our web-based education program and sleep disorders screening. By conducting a collaborative study involving sleep medicine clinicians, sleep researchers, a consultant on alarms, together with the representatives from the management, and union leadership of the fire department, we expect we will develop a sleep optimization program with a high probability of success and test the hypotheses that increasing the sleep opportunity of firefighters will improve the alertness, performance, safety and physical and mental health of firefighters. The results of this study will provide policy makers with the scientific evidence they require to develop effective fatigue countermeasure programs for firefighters. We will be conducting a randomized clinical trial, providing the most rigorous evaluation possible in an operational setting. Half the fire stations in a department will be randomly assigned to complete the intervention, termed Operation Fight Fatigue, in the first year of the study. The other half of the fire stations will complete the intervention in the second year. In this way, all firefighters will have the chance to benefit. We expect the fatigue countermeasure intervention to improve the alertness, performance, health and safety of firefighters. We will be evaluating a cost-effective intervention to improve the safety and health of firefighters in departments throughout the United States.

Interventions

Type	Name	Description
BEHAVIORAL	Sleep health education provided via a web-based program	All firefighters in the experimental group and controls will be asked to complete an approximately 30 minute education session. This education session will split into two modules, module 1: an introduction to the program along with basic sleeps hygiene information and module 2: standard training. Topics covered in module 2 will include basic sleep physiology, the causes and consequences of sleep disorders, and fatigue countermeasures. We will emphasize strategies to maximize sleep and reduce fatigue both on and off work.
OTHER	Sleep disorder detection and treatment	Firefighters in the intervention districts will complete a sleep disorders screening questionnaire. The questionnaire will focus on identifying individuals who show increased likelihood of suffering from obstructive sleep apnea, insomnia, shift work disorder, and restless legs syndrome using validated screening tools. Those assessed to be at high risk for one of these sleep disorders will be referred to a local AASM-accredited Clinical Sleep Disorders Service for evaluation and, if necessary, treatment. Diagnosis and treatment of sleep-related disorders will reduce the risk of fatigue-related accidents and improve the health and safety of affected individuals.
OTHER	Optimization of Sleep in Fire Station	First, we will review and retrofit the sleeping quarters to provide a better environment for napping and sleep; light, noise, bed type, space, temperature, and location would all be considered and where possible, changes made to improve the sleeping environment. Secondly, we will work with management and union personnel to develop a 'sleep friendly' policy during the daytime, with specified protected times for naps during the day before the overnight work in order to reduce sleepiness during overnight work. Finally, we will upgrade the alerting systems, that is, we will work with management and union personnel to consider changing the policy that requires the sleeping areas of all stations to receive all alarm calls, even if that particular station is not required to attend the alarm.
