Brief Summary:
Approximately half a million Americans annually experience venous thromboembolic disease, including deep venous thrombosis (DVT) and pulmonary embolism (PE). Since 2010, four new oral anticoagulants have been approved for marketing in addition to the vitamin K antagonist warfarin. Very limited head-to-head data exists comparing these treatment options, leaving patients, clinicians, and other stakeholders with little guidance for selecting the best strategy that balances recurrence reduction with risk of bleeding. In the DARE Warfarin CER Study, the researchers compare all five currently available oral anticoagulant agents for the extended treatment of DVT and PE, as well as no extended treatment. This study also aims to evaluate whether treatment heterogeneity exists for specific populations, such as older patients or those with renal dysfunction. In a secondary aim, the study will also leverage a database of linked electronic health record-insurance claims to validate diagnosis definitions and account for potential residual confounding by factors unmeasured in claims data. As the patient population includes all Medicare novel anticoagulant users and large numbers of commercially insured and Medicaid patients, the results will likely be transportable to the majority of US patients experiencing a DVT or PE. Pursuant to the objectives of the Patient-Centered Outcomes Research Institute, a study advisory committee consisting of key stakeholders will be actively involved in the study design and dissemination of results.
