Abstract

 Aims

To identify patterns of declining alertness at work among fixed night shift nurses using an objective measure and to determine the effect of sleep parameters on the decline in alertness at work.

Design

A prospective observational study.

Methods

Data were collected from 65 fixed night shift nurses who provided direct nursing care for patients in Korean hospitals between September 2020 and March 2021. Participants wore an actigraph for 14 days on their non-dominant hand to measure sleep parameters and predict their hourly alertness scores. They completed an online survey to provide their demographic information. Mixed-effect models were employed to determine the association between sleep parameters and the decline in alertness.

Results

The alertness scores of fixed night shift nurses constantly dropped every working hour. Scores dropped below 20% after 4 h from the beginning of the shift and below 30% after 6 h. Increased minutes in bed, minutes asleep and sleep efficiency reduced the risk of decreased alertness scores below 70. Increased sleep latency was associated with an increased risk of alertness scores dropping below 70.

Conclusion

The alertness of fixed night shift nurses drops steeply during regular hours and remains low during overtime. Sleep parameters contribute to the decline in alertness at work among fixed night shift nurses.

Impact

This study identified patterns of decline in alertness among fixed night shift nurses and the contributing factors for this decline, using an objective measure. The findings have important implications for the development of future interventions to improve the sleep hygiene of fixed night shift nurses to enhance their alertness at work.

目的

使用客观的测量方法确定固定夜班护士工作时警觉性下降的模式，并确定睡眠参数对工作时警觉性下降的影响。

设计

一项前瞻性的观察研究。

研究方法

收集了2020年9月至2021年3月期间在韩国医院为病人提供直接护理的65名固定夜班护士的数据。参与者在他们的非支配性手上佩戴了14天的测功仪，以测量睡眠参数并预测他们每小时的警觉性得分。他们完成了一项在线调查，以提供他们的人口统计信息。采用混合效应模型来确定睡眠参数和警觉性下降之间的关系。

结果

固定夜班护士的警觉性得分在每个工作小时内不断下降。在床上的时间、睡眠时间和睡眠效率的增加降低了警觉性分数低于70分的风险。睡眠潜伏期的增加与警觉性分数下降到70分以下的风险增加有关。

结论

固定夜班护士的警觉性在正常工作时间内急剧下降，在加班时仍然很低。睡眠参数有助于固定夜班护士工作时警觉性的下降。

影响

本研究使用客观的测量方法确定了固定夜班护士警觉性下降的模式和导致这种下降的因素。研究结果对今后制定干预措施以改善固定夜班护士的睡眠卫生以提高其工作警觉性有重要意义。
