Background: The incidence of bleeding complications in patients with venous thromboembolism (VTE) on new oral anticoagulants (NOACs) has not been widely studied in contemporary clinical practice in Africa. The purpose of this study was to determine the rates of major bleeding, clinically relevant non-major bleeding (CRNM) and minor bleeding associated with NOAC use.

Methods: A retrospective review was carried out of patients diagnosed with venous thromboembolism and treated with NOACs at the Aga Khan University Hospital, Nairobi, from January 2014 to December 2019.
