Thrombosis in Hospitalized Patients With COVID-19 in a New York City Health System

Educational Objective
To understand the risks of thrombosis in hospitalized patients with COVID-19
1 Credit CME

Patients with coronavirus disease 2019 (COVID-19) are at increased risk of thrombosis.1 However, studies have been limited in size, did not report all thrombotic events, and focused on patients with severe disease hospitalized in intensive care units (ICUs). We assessed the incidence of, and risk factors for, venous and arterial thrombotic events in all hospitalized patients with COVID-19 at a large health system consisting of 4 hospitals in New York City.
