目的:可以通过描述损伤严重程度趋势来加强创伤监测。这项研究报告了安大略省2004-2017年期间男性和女性工伤严重程度的趋势,加拿大。
方法:使用工人补偿福利支出的加权度量来定义伤害严重程度,从工人赔偿索赔与主要伤害或疾病归因于工作的急诊科(ED)记录的联系中获得。分母计数来自加拿大统计局的劳动力调查。每年伤害发生率的趋势,分类为低,中度,或严重程度高,使用回归模型进行检查,按年龄和性别分层。
结果:在14年的观察期内,分析中包括1,636,866条ED记录.总的来说,57.6%的职业伤害记录被归类为低严重程度,29.5%为中度严重程度,和12.8%为高严重性条件。女性中严重伤害的发生率有所增加(年变化百分比(APC):1.52%;95%CI:0.77,2.28),而男性和女性的中低严重伤害发生率普遍下降。在女性中,归因于有生命的机械力和攻击的伤害增加了低的原因,中度,和严重伤害。男性(APC:10.51%;95%CI:8.18,12.88)和女性(APC:16.37%;95%CI:13.37,19.45)脑震荡的发生率均增加。
结论:2004年至2017年间,安大略省女性的严重工伤发生率增加。在这项创伤性损伤严重程度的监测研究中应用的方法可以推广到其他司法管辖区的应用。
OBJECTIVE: Traumatic injury surveillance can be enhanced by describing injury severity trends. This study reports trends in work-related injury severity for males and females over the period 2004-2017 in Ontario, Canada.
METHODS: A weighted measure of workers\' compensation benefit expenditures was used to define injury severity, obtained from the linkage of workers\' compensation claims to emergency department (ED) records where the main injury or illness was attributed to work. Denominator counts were obtained from Statistics Canada\'s Labor Force Survey. Trends in the annual incidence of injury, classified as low, moderate, or high severity, were examined using regression modeling, stratified by age and sex.
RESULTS: Over a 14-year observation period, there were 1,636,866 ED records included in the analyses. Overall, 57.6% of occupational injury records were classified as low severity, 29.5% as moderate severity, and 12.8% as high severity conditions. There was an increase in the incidence of high severity injuries among females (annual percent change (APC): 1.52%; 95% CI: 0.77, 2.28), while the incidence of low and moderate severity injuries generally declined for males and females. Among females, injuries attributed to animate mechanical forces and assault increased as causes of low, moderate, and high severity injuries. The incidence of concussion increased for both males (APC: 10.51%; 95% CI: 8.18, 12.88) and females (APC: 16.37%; 95% CI: 13.37, 19.45).
CONCLUSIONS: The incidence of severe work-related injuries increased among females in Ontario between 2004 and 2017. The methods applied in this surveillance study of traumatic injury severity are plausibly generalizable to applications in other jurisdictions.
