病房护士的睡眠质量对日周性作业疲劳的影响

目的 探讨病房护士的睡眠质量对日周性作业疲劳的影响.方法 利用整群抽样的方法,调查了浙江省杭州市的3所三等甲级医院479名病房护士(非孕期、非病假)的睡眠质量及其日周性作业疲劳情况.采用匹茨堡睡眠质量指数量表(PSQI)评定睡眠质量;使用作业疲劳症状自评量表(2002)评定被调查对象1天的疲劳情况;自拟一般资料问卷收集护士的一般资料.结果 病房护士的睡眠质量普遍较差:PSQI总均分为7.31±3.45,PSQI7分的病房护士有200位(41.75%),睡眠总分与学历呈负相关(r=-0.11,P＜0.01),学历与睡眠质量、入睡时间和睡眠时间呈负相关;睡眠与婚姻、工龄、职称、职务无相关性.病房护士的睡眠质量与作业疲劳存在密切的关联:(1)睡眠总分与1天4个时间点的疲劳均分呈正相关(r值分别为0.42,0.34,0.25,0.33,P值均0.01).(2)睡眠总分与4个时间点疲劳的5个因子有相关性.(3)睡眠的7个因子之间以及4个时间点的疲劳均分之间也呈明显的相关.(4)睡眠质量与作业疲劳的多元回归分析结果显示,睡眠质量、日间功能、睡眠障碍以及催眠药物的使用是导致工作疲劳的重要因素.(5)睡眠质量与延迟下班无相关(r=0.06,P=-0.17).结论 应重视病房护士的睡眠质量,了解护士的工作疲劳程度,科学地安排工作任务和流程,合理地进行人力资源管理,注重睡眠卫生的宣传和教育,劳逸结合,提高病房护士的睡眠质量,降低工作疲劳感.

Effect of sleep quality on day cycle fatigue in ward nurses

OBJECTIVE: To explore the effect of sleep quality on day cycle work fatigue in ward nurses. METHODS: Through a cluster sampling of three hospitals, 479 clinical frontline nurses were investigated in hangzhou, Zhejiang, China. Using Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep quality; Using self-reported work-related fatigue symptom scale to evaluate day cycle fatigue status; common information was also collected. RESULTS: The sleep quality of ward nurses is generally poor, with total PSQI score 7.31 +/- 3.45. 41.75% ward nurses have total PSQI score over 7, the total PSQI score showed a negative linear correlation with educational background (r = -0.11, P = 0.01), educational background also represented a negative correlation with sleep quality, sleep latency and sleep duration; there are no correlation between sleep and marriage, work age, professional title and duty. Work-related fatigue was closely correlated with sleep quality: Total PSQI score showed a positive correlation with four daytime points fatigue in the next day (r = 0.42, r = 0.34, r = 0.25, r = 0.33, P < 0.01). Total PSQI score is also related to five fatigue factors in four daytime points. There are significant correlation between seven factors of sleep and fatigue levels of four time points. Multiple regression analysis showed that Sleep quality, day function; sleep disturbance and drug use pay important part in work fatigue. There is no correlation between sleep quality and delayed off-work (r = 0.06, P = 0.17). CONCLUSION: Managers should think highly of sleep quality of ward nurses, acknowledge its degree of work fatigue and apply evidence based methods arrange work responsibility and follow sheet, then rationalize human resources management, emphasize sleep hygiene education, improve sleep quality and reduce work fatigue.
