COVID-19 Registry to Assess Frequency, Risk Factors, Management, and Outcomes of Arterial and Venous Thromboembolic Complications (CORONA-VTE NET)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Novel coronavirus 2019 (COVID-19) has emerged as a major international public health concern. While much of the morbidity and mortality associated with COVID-19 has been attributed to acute respiratory distress syndrome (ARDS) or end-organ failure, emerging data suggest that disorders of coagulation, in particular hypercoagulability and venous thromboembolism (VTE), may represent an additional major, and possibly preventable, complication (Wu C, et al. JAMA Intern Med. 2020 Mar 13. \[Epub ahead of print\] and Tang N, et al. Thromb. Haemost. 2020 Feb 19. \[EPub Ahead of Print\]). Abnormal coagulation testing results, especially markedly elevated D-dimer and FDP, have been associated with a poor prognosis in COVID-19 infection. We propose the following Electronic Health Record (EHR)-guided 10000-patient, retrospective observational cohort study to assess VTE incidence, risk factors, prevention and management patterns, and thrombotic outcomes in patients with COVID-19 infection. In order to gain the valuable perspective of other regional and national centers providing care for large populations of COVID-19, we have started a collaborative network with 5 additional sites which will provide us with de-identified data from 1000 patients each. These 5000 patients in addition to the 5000-patient cohort we are enrolling within the Mass General Brigham Network will comprise this study population.
