Does Fatigue Coaching Improve Functioning and Fatigue in Resident Night Shifts

Fatigue Clinical Trial

Official title: Personalized Fatigue-Mitigation Lifestyle Coaching (PFMLC) to Improve Performance and Recovery Among Emergency Medicine Residents on Night Shifts

Status Not yet recruiting

Clinical Trial Summary

Emergency Medicine (EM) requires 24/7 staff coverage resulting in healthcare workers' circadian rhythm disruptions that impair clinical and cognitive performance, physical recovery, and contribute to burnout. Multiple well-being surveys continue to highlight EM's challenges with sleep impairment due to the nature of the specialty. Despite evidence that lifestyle strategies effectively optimize performance and recovery, EM residents have variable lifestyle choices to prepare for overnight shifts. This prospective randomized controlled trial will examine whether a pre-shift personalized fatigue-mitigation lifestyle coaching (PFMLC) for EM residents on overnight shifts minimizes the effects of circadian rhythm disruptions on performance and recovery compared to those who receive one-time passive information on lifestyle practices. All participants will receive lifestyle strategy materials on fatigue mitigation to improve performance. Residents' self-reported and biometric data will inform PFMLC in the active arm. Performance and recovery from night shifts will be assessed by changes in sleep, heart rate variability, readiness/recovery, alertness, cognitive performance, and mental health using Fitbit and validated measures.

Clinical Trial Description

The investigators will use a block-randomized design utilizing each 28-day scheduling period as a block.

Baseline characteristics and confounding factors such as gender, habitual diet, sleep, and caffeine intake will be collected on the first night of the study. Outcome measures will be assessed at the beginning of the shift and between the hours of 2:00 AM to 5:00 AM when sleep propensity and decreased alertness peak.

Outcome measures include a) Stanford Sleepiness Scale (SSS): which takes about 15 seconds to complete. b) Work Exhaustion (4 questions overall): take 20 seconds to complete. c) electronic psychomotor vigilance test: take 3 minutes to complete. The psychomotor vigilance test is a gamified method to measure both vigilance and reaction time. Done on a phone, a colored block appears on the screen, and when a participant sees the block, the participant taps the screen. Reaction time is measured in milliseconds and the average reaction time over the 3 minutes is calculated by the program and reported to the participant as well as stored in the participant's profile.

Study participants will be required to participate in the study for a total of 18 days. Each study participant will contribute biometric data for 7 days before a string of at least 4 consecutive night shifts, then for another 7 days (for a total of 18 days). A self-care handout containing nutrition tips for fatigue mitigation in night shift workers will be given to all participants at the beginning of the study. A Fitbit device will be provided to all participants to measure biometrics data.

Control: The investigators will not provide personalized coaching and ask the control participants to follow and record their typical nightshift habits. The control participants will participate in the surveys and tests as above. Control participants will receive a daily text message to remind them to do the surveys and tests during their shifts. The investigators will instruct the control participants to make sure their phones are silenced during this time as part of better habits for sleep. ;
