Shift workers regularly report sleep problems, fatigue, and the need for recuperative rest between shifts (intershift recovery). We sought to characterize intershift recovery among emergency medical services (EMS) workers and the role of worker demographics and work-related factors.
We combined cross-sectional survey data from two studies of EMS shift workers who completed standardized instruments, including the Occupational Fatigue Exhaustion Recovery (OFER) scale. A multivariable regression identified demographic and work factors most strongly associated with intershift recovery.
Mean intershift recovery among 450 EMS workers varied by clinical setting, general health status, length of work shift, sleep quality score, fatigue score, and daytime sleepiness. Recovery was better for EMS workers who report greater satisfaction with their schedule, higher for shift schedules >12 hours, and lowest for individuals who usually work 12-hour shifts.
In this sample of EMS workers, greater recovery between shifts is associated with satisfaction with scheduling and longer shift length. There were weaker associations of recovery with health status, sleep quality, and workplace fatigue. Future studies should address the relationship of intershift recovery with time off between shifts, workload, and workplace safety and performance.
轮班工作者经常报告睡眠问题、疲劳以及轮班间恢复性休息的需求（轮班间恢复）。我们试图描述紧急医疗服务（EMS）工作者的轮班间恢复情况以及工作者人口统计学特征和工作相关因素的作用。
我们合并了两项针对完成标准化工具（包括职业疲劳疲惫恢复（OFER）量表）的EMS轮班工作者研究的横断面调查数据。多变量回归确定了与轮班间恢复最密切相关的人口统计学和工作因素。
450名EMS工作者的平均轮班间恢复情况因临床环境、总体健康状况、工作时长、睡眠质量得分、疲劳得分和日间嗜睡程度而异。对排班满意度较高的EMS工作者恢复情况更好，超过12小时的轮班安排恢复情况较高，而通常上12小时轮班的个体恢复情况最低。
在这个EMS工作者样本中，轮班间更好的恢复与排班满意度和更长的轮班时长相关。恢复与健康状况、睡眠质量和工作场所疲劳的关联较弱。未来的研究应探讨轮班间恢复与轮班间隙休息时间、工作量以及工作场所安全和绩效之间的关系。
