Epidemological study of the relationship between night-shift, sleep problems and medical accidents among nurses

有人指出，睡眠问题可能与职业失误或险些失手有关。因此，关键是要揭示护士睡眠问题和医疗差错的实际情况，以便为讨论夜班或不定期工作的工人维持健康和防止职业差错的措施奠定基础。本研究以医院护士为调查对象，调查护士夜班工作与睡眠障碍的实际状况，分析夜班工作与各种医疗事故的关系。调查对象是8家配备400张床位或更多床位的医院的护士。回收问卷4407份，问卷回收率为94.0%。在医疗差错和夜班工作之间观察到了统计上的显著关系。睡眠时间的分布与医疗差错之间没有统计学上的显著关系。(1)入睡困难和白天过度困倦与(2)医疗差错有显著相关性，而(1)主观睡眠评估、睡眠维持困难、清晨觉醒和入睡困难与(2)医疗差错之间无统计学意义。

It has been pointed out that there may be associations between sleep problems and occupational mistakes or near-misses. It is therefore critical to reveal the actual statuses of sleep problems and medical mistakes among nurses in order to have a basis for discussion of measures for workers who work night or irregular shifts to maintain g6od health and to prevent occupational mistakes. In the present study, a survey was conducted targeting hospital nurses to examine the actual statuses of night-shift work and sleep disorders among nurses and to analyze associations between night-shift work and various medical accidents. The survey targets were nurses working in eight hospitals equipped with 400 beds or more. The number of responses was 4,407, and the collection rate of the questionnaire was 94.0%. A statistically significant relationship was observed between medical mistakes and night-shift work. No statistically significant relationship was observed between the distribution of sleep duration and medical mistakes. Statistically siqnificant relationships were observed between (1) difficulty in initiating sleep and excessive daytime sleepiness and (2) medical mistakes, but no statistically significant relationship was observed between (1) subjective sleep evaluation, difficulty in maintaining sleep, and early-morning awakening and difficulty in getting back to sleep and (2) medical mistakes.
