Objectives

Narrative objectives1

The coronavirus disease 2019 (COVID-19) has become a huge threat all over the world as a pandemic, which also could cause thrombosis including venous thromboembolism (VTE). Based on the concept of a high risk for thrombosis occurrence in patients with COVID-19, there could be a potential benefit of anticoagulation therapy for the primary prevention of thrombosis and treatment for COVID-19. However, the optimal strategies for the prevention of thrombosis and anticoagulation therapy in COVID-19 still remain unknown. Additionally, ethnic differences may have notable implications in the presentation of thrombosis. Unfortunately, there is a scarcity of data on current status of thrombosis and anticoagulation therapy in patients with COVID-19 in Japan. Thus, we are going to conduct the observational study to reveal the current status of thrombosis and anticoagulation therapy in patients with COVID-19 in Japan.

Results

In the present large-scale observational study, pharmacological thromboprophylaxis for hospitalized patients with COVID-19 was common especially in patients with severe COVID-19, and management strategies varied widely across the participating centers. The overall incidence of thrombosis was substantially low with an increased incidence according to the severity of the COVID-19.
