응급의학과 전문의들의 수면의 질 분석

Abstract

Purpose: Emergency physicians cannot help doing night shift, and consequentially their circadian rhythms are broken and sleep quality decrease. We investigate sleep quality and the factors related with it, and make a suggestion for improvement of sleep quality. Methods: A nationwide survey was conducted with a representative sample of 406 emergency medicine specialist doing medical practice in emergency department in 2015. Results: The mean time of all duties was 14, and night duties were 7 per four weeks. Over half respondents thought they have some sleep problem in recent two weeks and are worried about sleep. The most common symptoms they have after night shift were fatigue and tiredness, and the next one is impaired memory, concentration, and judgement. Average Epworth Sleepiness Scale (ESS) was 7.54 (min 0, max 24), and 19 respondents had serious sleepiness during day time and may need medical advice. There was no difference of sleep quality according to sex, and whether having uninterrupted nap during night shift. However, the respondents having regular schedule pattern had better sleep quality and less day time sleepiness. Higher ESS was correlated with less satisfaction on shift schedule, intenser duty work, physically and mentally unhealthiness. Conclusion: Over half respondents answered they have sleep-related problems, and complaint various symptoms after night shift. Emergency physicians having regular shift schedule had better sleep quality and less symptoms after night shift. This requires additional analysis for the practically possible pattern of shift schedule.
