Evaluating Worksite Sleep Health Coaching in Firefighters: The Sleep Assistance for Firefighters Study

Overview

Insufficient sleep is a significant public health issue, particularly affecting shift workers like firefighters, nearly half of whom report short or poor-quality sleep, with 35-40% screening positive for sleep disorders. Cognitive Behavioral Therapy for Insomnia (CBTi) is a recommended and effective treatment, but access to such interventions remains low. This study will recruit 20 fire agencies in Arizona (400 firefighters) to test if a CBTi-informed intervention, including sleep health coaching and agency-wide promotion, improves sleep more effectively than usual care. The trial will also explore factors that influence successful implementation across agencies.

Insufficient sleep is a major public health crisis in the United States and worldwide, disproportionately affecting shift workers and other at-risk groups. Firefighters are one such group at heightened risk for disturbed sleep. Almost half of career firefighters report short sleep and poor sleep quality, and 35-40% of firefighters screen positive for a sleep disorder. Evidence-based sleep health interventions are available and highly effective in eliciting behavioral change. The American College of Physicians recommends Cognitive Behavioral Therapy for Insomnia (CBTi) as the first-line treatment for Insomnia Disorder, and substantial evidence supports the efficacy of this therapy with comorbid conditions, including shiftwork and obstructive sleep apnea. Unfortunately, access to CBT-informed sleep health interventions remains low. Workplace wellness programs could be one way to help more firefighters receive sleep intervention. This study will recruit 20 fire agencies in Arizona (n = 400 career firefighters) to examine whether a CBTi-informed intervention is more effective than usual care in reducing sleep disturbances or improving multidimensional sleep health. The intervention will last one year and will include telephone-administered sleep health coaching to firefighters, sleep health promotion to the agency and agency leaders, and external/internal facilitation strategies for implementation. The trial will also examine which combinations of factors are associated with successful agency implementation of the intervention. All participating agencies will receive the intervention; however, some agencies will wait longer to receive the intervention than others.
