目的探讨基线(T1)间隔少于11小时的工作班次(快速返回)是否能预测护士在1年随访(T2)时的健康问题。方法对1224名护士在2009年(T1)和2010年(T2)进行问卷调查。在控制了年龄、性别、T1时相应的结果变量、T1时的夜班次数、T1到T2时的夜班次数、T1时的快速返回次数的变化和T2时的夜班次数后，采用粗略和调整后的Logistic回归分析来评估T1时的年快速返回次数与T2时的下列结果变量的关系：轮班工作障碍(SWD)、过度嗜睡(Epworth嗜睡量表)、病理性疲劳(Chalder疲劳量表)和焦虑抑郁(医院焦虑抑郁量表)。T2时95%可信区间为1.00~1.01，病理性疲劳为1.01，95%可信区间为1.00~1.01。从T1到T2的快速返回次数减少导致T2时病理性疲劳的风险降低(OR=0.67，95%CI为0.45至0.99)。在调整后的分析中，T1时的快速返回与T2时的过度嗜睡、焦虑或抑郁之间没有关联。结论这是第一项关于快速返回与未来健康问题之间关系的纵向研究。在1年的随访中，快速回报增加了SWD和病理性疲劳的风险。从一年到下一年减少快速回报的数量与发生病理性疲劳的风险降低有关。
Objectives We investigated whether the number of work shifts separated by less than 11 hours (quick returns) at baseline (T1) could predict health problems in nurses at 1-year follow-up (T2).Methods 1224 nurses responded to a questionnaire-based survey in 2009 (T1) and 2010 (T2). Crude and adjusted logistic regression analyses were completed to assess the association between annual number of quick returns at T1 and the following outcome variables at T2: shift work disorder (SWD), excessive sleepiness (Epworth Sleepiness Scale), pathological fatigue (Chalder Fatigue Scale) and anxiety and depression (Hospital Anxiety and Depression Scale), while controlling for age, gender, the corresponding outcome variable at T1, number of night shifts at T1, change in number of quick returns and number of night shifts from T1 to T2.Results The adjusted analyses showed that the annual number of quick returns at T1 predicted the occurrence of SWD (OR=1.01, 95% CI 1.00 to 1.01) and pathological fatigue (OR=1.01, 95% CI 1.00 to 1.01) at T2. A decreased number of quick returns from T1 to T2 entailed a reduced risk of pathological fatigue (OR=0.67, 95% CI 0.45 to 0.99) at T2. There was no association between quick returns at T1 and excessive sleepiness, anxiety or depression at T2 in the adjusted analyses.Conclusions This is the first longitudinal study investigating the associations between quick returns and future health problems. Quick returns increased the risk of SWD and pathological fatigue at 1-year follow-up. Reducing the number of quick returns from 1 year to the next was related to reduced risk of developing pathological fatigue.
