To explore the feasibility and effectiveness of an alternating shift pattern in two-hour segments in the state of emergency management of public health events.
A cross-sectional research design was conducted in our study. The nursing staff working in the admission ward of suspected or confirmed patients with COVID-19 in December 2022 were selected as subjects by the whole-group sampling method. We adopted a shift pattern of alternating shifts every two-hour in the isolation wards. The vital signs parameters were captured by uniformly wearing the multi-signs sensing devices, and the questionnaires collected the symptoms.
Sixty-seven female participants, with a mean age of 33.09 ± 5.96 years, were included in this study. Measurements of body temperature (T), blood oxygen saturation (SpO), respiratory rate (RR), and heart rate (HR) while wearing personal protective equipment (PPE) all remained within normal limits. None of the nurses reported sweating, dizziness, blurred vision, palpitations, or dyspnea. Statistical analysis showed significant differences between the critical care group and the non-critical care group in terms of age (P = 0.041), working duration (P = 0.036), and the total number of entries into isolation areas for nursing care (rounds) (P = 0.007). However, there were no statistically significant differences in vital signs based on age, work duration, or body mass index (BMI). The data indicated a notable increase in body temperature compared to other vital sign parameters with increasing work time while wearing PPE. Body temperature approached the upper limit when working close to 2 h long.
The alternating shift pattern in two-hour segments can effectively maintain the physical well-being of nurses wearing PPE without increasing the burden on nursing staff or the wastage of protective materials. This approach is recommended for addressing similar public health events in the future.
探讨在突发公共卫生事件应急管理状态下两小时分段交替轮班模式的可行性和有效性。
本研究采用横断面研究设计。通过整群抽样法选取2022年12月在新型冠状病毒肺炎疑似或确诊患者收治病房工作的护理人员作为研究对象。在隔离病房采用每两小时交替轮班的模式。通过统一佩戴多体征传感设备采集生命体征参数，通过问卷收集症状。
本研究纳入67名女性参与者，平均年龄为33.09±5.96岁。佩戴个人防护装备（PPE）时的体温（T）、血氧饱和度（SpO）、呼吸频率（RR）和心率（HR）测量值均保持在正常范围内。没有护士报告出汗、头晕、视力模糊、心悸或呼吸困难。统计分析显示，重症护理组和非重症护理组在年龄（P = 0.041）、工作时长（P = 0.036）以及进入隔离区进行护理的总次数（轮次）（P = 0.007）方面存在显著差异。然而，基于年龄、工作时长或体重指数（BMI）的生命体征没有统计学上的显著差异。数据表明，与其他生命体征参数相比，佩戴PPE工作时间增加时体温显著升高。工作接近2小时时体温接近上限。
两小时分段交替轮班模式可以有效维持佩戴PPE护士的身体健康，而不会增加护理人员的负担或防护物资的浪费。建议采用这种方法应对未来类似的突发公共卫生事件。
