Abstract
INTRODUCTION: SARS-CoV-2 (COVID-19) infection and multisystem inflammatory syndrome in children (MIS-C) are risk factors for venous thromboembolism (VTE). Guidelines for VTE prophylaxis were established at our institution at the beginning of the pandemic. Patients who had any VTE risk factors in addition to COVID-19 met criteria for anticoagulation prophylaxis. Patients who were diagnosed with MIS-C met criteria regardless of additional risk factors.
MATERIALS AND METHODS: We conducted a retrospective review of patients admitted with COVID-19 or MIS-C to determine compliance with VTE prophylaxis guidelines and to evaluate the incidence of VTE and bleeding events in our population.
RESULTS AND CONCLUSIONS: Among a total of 678 patients admitted with COVID-19 or MIS-C, 519 (76 %) patients met criteria for VTE prophylaxis and 348 (65.6 %) started prophylaxis. Logistic regression analysis identified a personal or family history of thrombosis or thrombophilia, diagnosis of MIS-C, admission to the intensive care unit, and presence of a central venous catheter as significantly associated with starting VTE prophylaxis. There were 18 patients who developed VTE. Minor bleeding events occurred in 19 patients (5 %), patient important bleeding, no intervention occurred in 8 patients (2 %), clinically relevant nonmajor bleeding in 8 patients (2 %), and major bleeding in 10 patients (3 %). The incidence of VTE in our patients with COVID-19 and MIS-C is similar to VTE rates at other institutions. We found that universally recognized VTE risk factors were appropriate to include as risk factors for thrombosis in hospitalized children with COVID-19 and MIS-C.
