Thrombotic Events in COVID-19 Patients Not Requiring Hospitalization at the Time of Diagnosis

To inform future sample size calculations pertaining to thrombosis in COVID-19-associated coagulopathy, we describe occurrence of thrombotic events and death among patients aged 40-79 years not hospitalized at the time of COVID-19 identification. We used electronic health record (EHR) data from 64 health care organizations (including inpatient and outpatient data), provided through the TriNetX Live™ platform in their USA network to identify COVID-19 cases in the outpatient setting from February 20, 2020 through September 11, 2020.
