Coagulopathy of COVID-19: A Pragmatic Randomized Controlled Trial of Therapeutic Anticoagulation Versus Standard Care

Summary

Coagulopathy of COVID-19 afflicts approximately 20% of patients with severe COVID-19 and is associated with need for critical care and death. COVID-19 coagulopathy is characterized by elevated D-dimer, an indicator of fibrin formation and clot lysis, and a mildly prolonged prothrombin time, suggestive of coagulation consumption. To date, it seems that COVID-19 coagulopathy manifests with thromboembolism, thus anticoagulation may be of benefit. We propose to conduct a parallel pragmatic multi-centre open-label randomized controlled trial to determine the effect of therapeutic anticoagulation compared to standard care in hospitalized patients admitted for COVID-19 with an elevated D-dimer.
