Shift-Work Sleep Disorder | Fire Fighter Fatigue Management Program: Operation Fight Fatigue

Shift-Work Sleep Disorder research study

What is the primary objective of this study?

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.

Who is eligible to participate?

Inclusion Criteria: - Must be a fire department employee at a participating fire department. Exclusion Criteria: - May not be 17 years of age or younger. - Will not be included if not a firefighter.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Shift-Work Sleep Disorder

Insomnia

Restless Leg Syndrome

Obstructive Sleep Apnea

Impaired Driving

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Behavioral:Sleep health education provided via a web-based programAll 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 treatmentFirefighters 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 StationFirst, 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.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

InterventionFirefighters in this group will receive at the beginning of the study an introduction to the study, sleep education, sleep disorder screening survey, health survey, increased sleep opportunities at their fire department, followed later by physiological monitoring of a portion of the firefighters, and then finally an 'end of year' survey at the end of the study.

ControlFirefighters in this group will only receive an introduction to the study and a health survey, followed later by physiological monitoring of a portion of the firefighters, and then at the end of the study will receive the sleep disorders screening survey, sleep education (Intervention group received screening survey and education much earlier at the beginning of the study), and an 'end of year' survey. None of these firefighters will receive the increased sleep opportunities as the Intervention group will.
