Anticoagulation in COVID-19: A systematic review, meta-analysis and rapid guidance from the mayo clinic

Abstract

A higher risk of thrombosis has been described as a prominent feature of COVID-19. This systematic review synthesizes current data on thrombosis risk, prognostic implications, and anticoagulation effects in COVID-19. We included 37 studies from 4,070 unique citations. Meta-analysis was performed when feasible. Coagulopathy and thrombotic events were frequent among patients with COVID-19, and further increased in those with more severe forms of the disease. We also present guidance on the prevention and management of thrombosis from a multidisciplinary panel of specialists from the Mayo Clinic. The current certainty of evidence is generally very low, and continues to evolve.
