The MICHELLE Trial: Anticoagulation Post-Discharge in Patients Hospitalized Secondary to COVID-19

Background:Patients diagnosed with COVID-19 have an increased risk of thromboembolic events, including pulmonary embolism and deep vein thrombosis (DVT). In addition, COVID-19 patients with increased coagulation parameters such as D-dimer, fibrin degradation products, prothrombin time, and activated partial thromboplastin time are at higher risk of morbidity and mortality.
Several RCTs have investigated the benefit of anticoagulation in patients with COVID-19 in various clinical settings. The INSPIRATION Trial investigated outcomes with an intermediate vs. standard prophylactic dose of anticoagulation in ICU patients. A multiplatform trial and HEP-COVID Trial investigated therapeutic anticoagulation in critically ill and non-critically ill hospitalized patients. The ACTIV-4B Trial investigated anticoagulation in symptomatic COVID-19 patients who did not require hospitalization. Currently, there is some evidence in support of therapeutic anticoagulation in non-critically ill hospitalized patients. However, there is no evidence to support the use of full dose anticoagulation in either the ICU or outpatient setting.
