Abstract

Background: The disproportionate impact of coronavirus disease (COVID-19) on healthcare workers has been highlighted; however, there is a lack of evidence regarding other high-risk occupations and industries.

Aims: This study estimated the risk of severe COVID-19 among a large cohort of workers in Ontario, Canada.

Methods: This study used a cohort of 1.2 million workers identified using workers' compensation claims records (1983-2019). Identified workers were linked with emergency department (ED) visits and hospitalizations (2020-2021). Cases coded as U0.71 (virus detected, confirmed case) were identified from ED visits and hospitalizations. Hazard ratios (HRs) and 95% confidence intervals (CI95%) for COVID-19 for each occupational group compared to all other workers in the cohort were calculated, adjusting for age and birth year. Standardized incidence ratios and 95% CI, comparing workers to the general population of Ontario were also calculated, adjusting for age, sex, year and region.

Results: A total of 10 322 severe COVID-19 cases among workers were identified through ED visits and hospitalizations. Workers in material handling (HR=1.32, CI95%=1.21-1.43), medicine and health (HR=1.27, CI95%=1.18-1.37), processing (food, water, textile) (HR=1.23, CI95%=1.12-1.36) and machining occupations (HR=1.11, CI95%=1.02-1.20) had some of the highest risks of COVID-19 when compared to all other workers in the cohort. Findings were somewhat consistent when comparing workers to the general population of Ontario.

Conclusions: Certain groups of workers in this cohort demonstrated elevated risks of severe COVID-19. The findings align with previous studies and emphasize the need to include occupational surveillance methods in future pandemic preparedness in Canada.

加拿大安大略省120万工人中严重COVID-19的发病率
背景:冠状病毒病(COVID-19)对医护人员的不成比例的影响已得到强调;然而,缺乏关于其他高风险职业和行业的证据。目的:本研究估计了加拿大安大略省一大批工人患严重COVID-19的风险。方法:本研究使用了120万名工人的队列,这些工人是通过工人赔偿索赔记录(1983-2019)确定的。确定的工人与急诊(ED)就诊和住院(2020-2021年)有关。编码为U0.71(检测到病毒,确诊病例)的病例是从急诊室就诊和住院中确定的。计算每个职业组与队列中所有其他工人相比的COVID-19风险比(hr)和95%置信区间(CI95%),并根据年龄和出生年份进行调整。在调整了年龄、性别、年份和地区后,还计算了安大略省工人与普通人群的标准化发病率和95% CI。结果:通过急诊科就诊和住院治疗,共发现工作人员重症病例10 322例。与队列中所有其他工人相比,从事物料搬运(HR=1.32, CI95%=1.21-1.43)、医药卫生(HR=1.27, CI95%=1.18-1.37)、加工(食品、水、纺织)(HR=1.23, CI95%=1.12-1.36)和机械加工(HR=1.11, CI95%=1.02-1.20)的工人感染COVID-19的风险最高。当将工人与安大略省的一般人口进行比较时,结果有些一致。结论:该队列中的某些工人组显示出严重COVID-19的风险升高。这些发现与以前的研究结果一致,并强调有必要在加拿大未来的大流行防范中纳入职业监测方法。

期刊介绍: Occupational Medicine is an international peer-reviewed journal which provides vital information for the promotion of workplace health and safety. The key strategic aims of the journal are to improve the practice of occupational health professionals through continuing education and to raise the profile of occupational health with key stakeholders including policy makers and representatives of employers and employees. Topics covered include work-related injury and illness, accident and illness prevention, health promotion, occupational disease, health education, the establishment and implementation of health and safety standards, monitoring of the work environment, and the management of recognized hazards. Contributions are welcomed from practising occupational health professionals and research workers in related fields.
