Abstract
OBJECTIVE: Excessive daytime sleepiness (EDS) in emergency medicine (EM) residents is associated with patient safety. However, studies regarding EDS in EM residents are limited. The objective of this study was to identify the prevalence of EDS and its associated factors among EM residents. METHODS: Epworth sleepiness scale scores, working hours per week (WHW), night working days per month, working environment, and depression were analyzed using data from the 2019 Korean Emergency Medicine Resident Survey. RESULTS: The survey response rate was 63.8% (384/601). Among 241 respondents, the prevalence rate of EDS was 32.4%. Multivariable logistic regression analysis demonstrated that WHW (odds ratio [OR] = 1.03, 95% confidence interval [CI] = 1.01-1.06) and depression (OR = 3.64, 95% CI = 1.91-6.96) had increased ORs for EDS. CONCLUSIONS: Approximately one-third of EM residents had EDS. Depression and WHW were the associated factors.
