目的了解2004-2008年安大略省工人24小时工作期间的工伤发生率。方法采用两个独立的数据来源（损失时间赔偿索赔和急诊科就诊记录），对职业活跃的成年人进行工伤和疾病的横断面观察研究。安大略省劳动力按一天中的时间、年龄、性别和职业分列的年工作时数是根据基于人口的调查估计的。结果因工作相关疾病就诊的急诊科发生率比因工伤损失索赔的发生率高约40%（急诊科记录707 933份，工伤损失索赔457 141份）。在这两个行政数据来源中，对于男性和女性以及所有年龄组来说，晚上、夜间和清晨期间与工作有关的伤害或疾病的风险较高。这种升高的风险在手工、混合和非手工职业群体中一致观察到。在损失时间赔偿索赔中，可归因于夜间或夜间工作时间表中工伤风险增加的比例在女性中为12.5%，在男性中为5.8%。结论：尽管在发达经济体中，非白天工作时间的就业率很高，但与晚间和夜间工作时间相关的工伤危险仍然相对不明显。这项研究表明，利用行政数据源提高按时间对工伤风险进行监测的能力是可行的。需要进行更复杂的病因学研究，以了解与不规律工作时间有关的危害的具体机制。
Objective To estimate the rate of work injury over the 24 h clock in Ontario workers over 5 years (2004-2008).Methods A cross-sectional, observational study of work-related injury and illness was conducted for a population of occupationally active adults using two independent data sources (lost-time compensation claims and emergency department encounter records). Hours worked annually by the Ontario labour force by time of day, age, gender and occupation were estimated from population-based surveys.Results There was an approximately 40% higher incidence of emergency department visits for work-related conditions than of lost-time workers' compensation claims (707 933 emergency department records and 457 141 lost-time claims). For men and women and across all age groups, there was an elevated risk of work-related injury or illness in the evening, night and early morning periods in both administrative data sources. This elevated risk was consistently observed across manual, mixed and non-manual occupational groups. The fraction of lost-time compensation claims that can be attributed to elevated risk of work injury in evening or night work schedules is 12.5% for women and 5.8% for men.Conclusions Despite the high prevalence of employment in non-daytime work schedules in developed economies, the work injury hazards associated with evening and night schedules remain relatively invisible. This study has demonstrated the feasibility of using administrative data sources to enhance capacity to conduct surveillance of work injury risk by time of day. More sophisticated aetiological research is needed to understand the specific mechanisms of hazards associated with non-regular work hours.
