Epworth sleepiness scale in medical residents: quality of sleep and its relationship to quality of life

BACKGROUND: Resident doctors are continuously exposed to prolonged working hours and night shifts, making them susceptible to the many physical, psychological, and cognitive side effects of sleep deprivation, which may affect their quality of life. Therefore, this study aimed to determine the prevalence of sleep penury in resident doctors and to assess the association between self-apprehended sleepiness and quality of life. METHODS: A cross-sectional study was carried out in the governmental hospitals in the North of the West Bank between May 2017 and September 2017. Doctors enrolled in residency programmes completed questionnaires about general, sociodemographic, and sleep characteristics. The doctors completed the Arabic Version of the Epworth Sleepiness Scale (ArESS) to assess subjective daytime sleepiness and the RAND 36-item short-form health survey (SF-36) to determine quality of life. RESULTS: A total of 101 participants were enrolled. Daytime sleepiness was observed in 37.6% (n = 38) of the participants with an ESS score of ≥10. There was a notable negative correlation between the ESS and quality of health index in the physical composition (r = − 0.351, p < 0.001) demonstrated in the following four subscales: the physical functioning (p < 0.001), role limitations due to physical health (p = 0.045), body pain (p = 0.036), and general health (p < 0.001) components of the SF-36 scale. Females and residents of the centre region had poorer mental quality (p = 0.006 and 0.020, respectively). CONCLUSIONS: More than one third of the resident doctors suffer from daytime sleepiness according to the ESS. This was proven to significantly affect several aspects of their quality of life, including physical function and health, body pain, and general health. Sleep deprivation and improvement of quality of life require health promotion actions among medical residents.
