这项研究考察了休息时间对工业事故风险的时间趋势的影响，试图复制早期的发现，即风险随着工作时间的推移而线性增加。在两项独立的研究中，研究了工伤趋势与休息时间的关系。在研究一中，比较了一家大型工程公司每周轮换三班制的在轨和脱轨工人。检查了超过12个月的工伤记录(N=4645起)。研究二涉及采访在不同职业环境中遭受工伤的患者(N=407名患者)。两项研究均采用层次对数线性分析。在研究一中，从休息后连续工作的第一个半小时到第二个半小时，风险增加，但在随后的半个小时中保持相对稳定，尽管在轨工人的第三个半小时有所下降。在一些数据中，在工作期结束前的一段时间内，风险也有所下降。报告的受伤人数在轮班接近尾声时急剧下降，但除此之外，观察到的趋势在连续工作期间或上午、下午和夜间轮班之间没有不同。在研究二中，从连续工作的第一个半小时到第二个半小时，风险增加，然后在第三个半小时内保持相对稳定。目前和之前的研究结果之间的反差可能是由于之前研究相对独特的工作环境造成的。有人认为，目前的趋势反映了在相对不受限制的任务环境中工作的影响，而疲劳以外的原因可能是先前和当前研究中观察到的趋势的基础。
This study examined the impact of rest breaks on temporal trends in industrial accident risks in an attempt to replicate earlier findings of a linear increase in risk as a function of elapsed time on task. In two separate studies, the trend in work‐related injuries were studied in relation to the timing of rest breaks. In study one, comparisons were made between on‐ and off‐track workers on weekly rotating three‐shift systems operating in a large engineering company. Records of on‐duty injuries that occurred over 12 months were examined (N=4645 incidents). Study two involved interviewing patients who had suffered work‐related hand injuries in a variety of occupational settings (N=407 patients). Hierarchical log linear analysis was used in both studies. In study one, risk increased from the first to the second half‐hour of continuous work following a break, but then remained relatively constant in subsequent half‐hour periods, although there was a fall in the third half‐hour for on‐track workers. In some of the data, there was also a decrease in risk in the period leading up to the end of a work period. There was a sharp decline in reported injuries toward the very end of a shift, but otherwise the observed trends did not differ between successive periods of continuous work or between morning, afternoon, and night shifts. In study two, risk increased from the first to the second half‐hour of continuous work and then remained relatively constant in the third half‐hour. The contrast between the current and previous findings may be due to the relatively unique work environment of the previous study. It is suggested that the current trends reflect the effects of working in a relatively unconstrained task environment, and that causes other than fatigue may underlie the trends observed in both the previous and current studies.
