Hospitalized Arterial and Venous Thrombotic Events in Patients Diagnosed in the Ambulatory Setting with COVID-19 Compared to Influenza

Studies of hospitalized COVID-19 patients suggest an increased risk of arterial thromboembolism (ATE) and venous thromboembolism (VTE). The incidence and determinants of these events after COVID-19 diagnosis in the ambulatory setting are less clear.

This presentation estimates the risk of ATE and VTE among patients with ambulatory-diagnosed COVID-19 before and during COVID-19 vaccine availability compared to patients with ambulatory-diagnosed influenza. It was presented at the 39th International Conference on Pharmacoepidemiology and Therapeutic Risk Management.
