Role of anticoagulants contraindications, adherence, and drug cost-sharing on racial disparity in the prescription of novel oral anticoagulants and future risk of thromboembolic stroke

Project: Research project

Project Details


Oral anticoagulation (OAC) reduces thromboembolic events associated with atrial fibrillation (AF), yet 50% of AF patient are not prescribed OAC. Recent studies, including our preliminary findings, also showed significant racial disparity in OAC prescription even after accounting for access to care, health insurance and stroke risk factors. In this study, we will evaluate whether amount of drug cost-sharing, supplemental coverage and OAC contraindications explain OAC underuse and racial disparity in prescription of OAC in AF patients.
