Venous Thrombosis Virtual Surveillance in COVID (VVIRTUOSO)

COVID-19 Research Area(s): Healthcare Delivery & Policy

The overall goal of the VVIRTUOSO study determine the rate of venous thrombosis after hospital discharge in 500 patients with COVID-19 using a virtual monitoring program at 12 sites in Canada and the United States. We will also explore factors that increase the likelihood of venous thrombosis. As part of this study, we will also assess VTE awareness and patient-reported quality of the monitoring program (quality of communication and patient satisfaction). Our multidisciplinary team includes researchers, clinicians, patient partners and collaborators Thrombosis Canada ( and the CanVECTOR Network ( We have the necessary experience, existing research network infrastructure, and knowledge translation mechanisms to successfully complete this study and disseminate the results rapidly and widely.
