Temporal changes in occupational risks of COVID-19 hospitalisation in Germany, 2020-2021: a case-cohort study.

ABSTRACT:

Background

During the COVID-19 pandemic, certain occupational groups faced elevated infection risks. This study investigated changes in occupational risks of COVID-19 hospitalisation between 2020 and 2021.

Methods

Using a case-cohort design, we analysed data from Germany's Allgemeine Ortskrankenkasse statutory health insurance, including 28 925 COVID-19 hospitalisation cases and 498 484 non-cases in 2021. HRs with administrative workers as reference were calculated using weighted and stratified Cox regression models, adjusting for age, sex, comorbidities and socioeconomic status. The ratio of relative risk (RRR) assessed the differences between years.

Results

Healthcare workers showed the greatest reduction in relative risk (HR₂₀₂₀=2.74, 95% CI 2.46 to 3.05
