• Study description:
  The aim of the study is to contextualize the risk of venous and arterial thromboembolic events associated with COVID-19, during the Omicron period, and SARS-CoV-2 vaccination. The research objectives which will be addressed incrementally to support the project aim are to estimate the background incidence rate of venous and arterial thromboembolic events among the general pre-pandemic population, to estimate the incidence rate of venous and arterial thromboembolic events among patients with COVID-19 within 30-, 60-, and 90- and 180-days during the Omicron period, stratified by prior SARS-CoV-2 vaccination and prior infection status, to estimate the incidence rate of venous and arterial thromboembolic events among patients with SARS-CoV-2 vaccination within 30-, 60-, 90- and 180-days, stratified by prior infection status, to estimate the association between clinical risk factors including prior SARS-CoV-2 vaccination on the incidence rate of venous and arterial events among patients with COVID-19 and the impact that thromboembolic events have on worsening severity of COVID-19 during the Omicron period and to estimate incidence rate ratios for venous and arterial thromboembolic events among patients with COVID-19 and people vaccinated against SARS-CoV-2, compared to the background population using incidence rates estimated in objectives 1 to 3.
