Cost and clinical outcomes in the use of new oral anticoagulants versus warfarin in deep vein thrombosis: A systematic review protocol

Review question / Objective: What are the benefits of using new oral anticoagulants compared to warfarin in terms of efficacy, bleeding, and cost among people with deep vein thrombosis? This study aimed to compare the effectiveness, bleeding incidence, and cost between NOAC and warfarin in DVT patients. Condition being studied: The patient confirmed DVT with the results of the Wells' score and D-dimer test stating "possible DVT" and followed by an ultrasound examination which stated "DVT positive". Patients are taking oral anticoagulants to treat DVT or to prevent a recurrence. Oral anticoagulants consist of apixaban, rivaroxaban, edoxaban, dabigatran, and warfarin.
