自我监控当前表现的认知能力对于医院护士维护安全和健康是重要的。然而，关于轮班工作对自我监控能力影响的研究还很少。我们研究了30名病房女护士(平均年龄28.2 岁)在轮换三班制中自我监测准确性的差异。他们的自我监控能力是通过从实际反应时间中减去在离开工作场所前执行的精神运动警戒任务的预测反应时间来计算的。使用混合效应模型来评估轮班、清醒时间和先前睡眠时间对自我监控能力的影响。我们观察到护士的自我监控能力受损，尤其是在上夜班之后。尽管所有班次的实际表现仍然很高，但他们在夜班时对反应时间的自我预测变得悲观，导致大约−100毫秒的差异。即使在调整了睡眠时间和清醒时间后，这种转变对自我监控的影响也是明显的。我们的发现表明，他们的工作时间和昼夜节律之间的不一致可能会影响到甚至专业护士。强调维持昼夜节律的职业管理将提高护士的安全和健康。
The cognitive ability to self-monitor one’s current performance is important for hospital nurses to maintain safety and health. However, studies on the effects of rotating shift work on self-monitoring ability are insufficient. We examined the differences in self-monitoring accuracy across shifts in a rotating three-shift system among 30 female ward nurses (mean age 28.2 years). Their self-monitoring ability was calculated by subtracting the predicted reaction times of the psychomotor vigilance task performed just before exiting the workplace from the actual reaction times. A mixed-effect model was employed to assess the effects of shift, awake hours, and prior sleep duration on self-monitoring ability. We observed impaired self-monitoring ability in nurses, particularly after the night shift. Although actual performance remained high across all shifts, their self-predictions on reaction times became pessimistic in the night shift, resulting in a difference of approximately−100 msec. The effect of the shift on self-monitoring was obvious even after adjusting for sleep duration and hours awake. Our findings indicate that the misalignment between their working hours and circadian rhythms may affect even professional nurses. Occupational management that emphasizes maintaining circadian rhythms will improve the safety and health of nurses.
