Practice guidelines of thromboprophylaxis and management of anticoagulation in hospitalized patients with COVID-19

Abstract

Corona virus disease 2019 (COVID-19) can lead to thrombotic complications through multiple mechanisms. Venous thromboembolism (VTE) is one of the most important causes of death or poor prognosis in hospitalized patients with COVID-19. The prognosis of thrombosis in COVID-19 patients can be improved with VTE and bleeding risk assessment, as well as appropriate VTE prophylaxis. However, in current clinical practice, there still is much room for progress in choose of appropriate prevention methods, anticoagulant regimens, doses, and courses based on the severity and specific condition of COVID-19 patients and dynamically balancing the risk of thrombosis and bleeding. In the past three years, a series of authoritative guidelines related to VTE and COVID-19 and high-quality, evidence-based medical research evidence have been released both in domestic and internationally. Based on this, in order to better guide the clinical practice in China, multi-discipline expert discussions and Delphi expert demonstrations formulated the"Thromboprophylaxis and management of anticoagulation in hospitalized patients with COVID-19: an update of the CTS guidelines", aiming to address the issues of thrombosis risk and prevention strategies caused by COVID-19, anticoagulant management of hospitalized patients, diagnosis and treatment of thrombosis, anticoagulant management of special populations, interaction and adjustment strategies of antiviral and anti-inflammatory drugs and anticoagulant drugs, follow-up after discharge and many other aspects of clinical situations. Recommendations and clinical guidelines are provided for appropriate thromboprophylaxis and anticoagulation management strategies for VTE in patients with COVID-19.
