Association of current work, sleep situation and medical incidents among Japanese physicians

目的：本研究的目的是阐明日本医生目前的工作和睡眠状况，以及这些状况与日间过度嗜睡和医疗事故之间的关系。方法：对日本医科大学在校生进行自填式问卷调查。随机选择的受试者包括1165名医生。结果：共获得955名医生的有效问卷。男性平均睡眠时间为6小时13分钟，女性为6小时1分钟。睡眠不足的患病率男性为28.4%，女性为30.6%；失眠患病率分别为21.0%和18.1%；EDS患病率为17.3%。对于报告睡眠时间短、由于睡眠不足而缺乏休息、高频率待命/通宵工作的医生来说，EDS的调整后的优势比很高。在过去一个月内经历过医疗事故的医生占24.7%。对于工作时间长、高频率随叫随到/通宵工作、因睡眠不足而缺乏休息和失眠的人，医疗事故的调整优势比很高。结论：为了促进医生的最佳健康管理，确保医疗安全，充分考虑医生的工作和睡眠情况是很重要的。

OBJECTIVE : The aim of the present study was to clarify the current work and sleep situations of physicians in Japan and to clarify the association between these situations and excessive daytime sleepiness as well as medical incidents. METHODS : A self-administered questionnaire survey was conducted among the members of the Nihon University of Medicine. The randomly selected subjects comprised 1, 165 physicians. RESULTS : Valid responses were obtained from 955 physicians. Mean sleep duration was 6 h 13 min for men and 6 h 1 min for women. The prevalence of lack of rest due to sleep deprivation was 28.4% among men and 30.6% among women ; the prevalence of insomnia was 21.0% and 18.1%, respectively ; and the prevalence of EDS was 17.3%. The adjusted odds ratio for EDS was high for physicians who reported short sleep duration, lack of rest due to sleep deprivation, and a high frequency of on-call/overnight work. Physicians who had experienced a medical incident within the previous one month accounted for 24.7% of participants. The adjusted odds ratio for medical incidents was high for those subjected to long working hours, high frequency of on-call/overnight works, lack of rest due to sleep deprivation, and insomnia. CONCLUSION : In order to facilitate optimal health management for physicians as well as securing medical safety, it is important to fully consider the work and sleep situations of physicians.
