Venous Thromboembolism in Patients Discharged after COVID-19 Hospitalization

Abstract Background Venous thromboembolism (VTE) is a frequent complication of COVID-19, so that the importance adequate in-hospital thromboprophylaxis in patients hospitalized with COVID-19 well established. However, incidence VTE after discharge and whether postdischarge beneficial safe are unclear. In this prospective observational single-center study, we report 6 weeks hospitalization use thromboprophylaxis. Methods Patients confirmed were invited to multidisciplinary follow-up clinic discharge. D-dimer C-reactive protein measured, all screened for deep vein thrombosis venous duplex-ultrasound. Additionally, selected high-risk received computed tomography pulmonary angiogram or ventilation–perfusion (V/Q) scan screen incidental embolism. Results Of 485 consecutive from March through June 2020, 146 analyzed, which 39% had been admitted intensive care unit (ICU). Postdischarge was prescribed 28% patients, but used more frequently ICU stay (61%) higher maximal levels during hospitalization. Six discharge, elevated values present 32% ward 42% patients. Only one asymptomatic (0.7%) symptomatic embolism diagnosed systematic screening. No bleedings reported. Conclusion who screening revealed low VTE. A strategy selectively providing seems potentially effective.
