To determine the effects of sleep parameters and fatigue on the decline in alertness of nurses across shifts.
Shift work can lead to nurse fatigue owing to insufficient sleep and inadequate recovery time between shifts. Nurse fatigue has adverse effects on alertness and can affect provision of quality care.
An observational study using wrist actigraphs was conducted from 2019 to 2020. Participants were 82 rotating-shift nurses who provided direct nursing care in acute hospitals in South Korea. They wore actigraphs for 14 days to measure sleep parameters and predict hourly alertness and reported subjective fatigue before and after every shift.
Nurses demonstrated shorter sleep hours, lower sleep efficiency and longer sleep latency before night shifts compared with other shifts. Fatigue was the highest before day shifts. Sleep parameters and fatigue significantly affected the steep decline in alertness in participants with alertness scores below 70.
Sleep parameters and fatigue level contributed to the differences in decline in alertness across shifts.
Findings inform nurse managers, administrators to develop interventions to reduce fatigue, improve sleep quantity and quality and increase alertness among rotating-shift nurses. Management, institutional and individual factors should be considered when developing interventions.
确定睡眠参数和疲劳对轮班护士警觉度下降的影响。
由于睡眠不足和轮班之间恢复时间不足，轮班工作可能导致护士疲劳。护士疲劳对警觉度有不良影响，并可能影响提供高质量的护理。
这是一项 2019 年至 2020 年进行的观察性研究，使用腕部活动记录仪。参与者是韩国急性医院提供直接护理的 82 名轮班护士。他们佩戴活动记录仪 14 天，以测量睡眠参数并预测每小时的警觉度，并在每次轮班前和轮班后报告主观疲劳。
与其他班次相比，护士在夜班前的睡眠时间更短、睡眠效率更低、睡眠潜伏期更长。疲劳在白班前最高。睡眠参数和疲劳显著影响警觉度得分低于 70 的参与者警觉度的急剧下降。
睡眠参数和疲劳水平导致警觉度在轮班之间的差异。
研究结果为护士长和管理人员提供了信息，以制定干预措施，减少疲劳，提高睡眠质量和数量，并提高轮班护士的警觉度。在制定干预措施时，应考虑管理、机构和个人因素。
