93 Adherence to Direct Oral Anticoagulants among U.S. Veterans with Atrial Fibrillation in the Era of the Veteran Health Administration DOAC Population Management Tool

Introduction: An estimated one-third of atrial fibrillation (AF) patients treated with a Direct Oral Anticoagulant (DOAC) are considered non-adherent, increasing the risk of stroke and systemic embolism (SSE). Minimal resources to automatically identify non-adherence or measure adherence over time exist. The DOAC Population Management Tool (PMT) alerts clinicians to non-adherence and supports program management by benchmarking facility and healthcare system adherence rates. The purpose of this evaluation is to describe DOAC adherence using the PMT within Veteran Heath Administration (VHA) where anticoagulation stewardship is commonplace, and an electronic population health tool is widely available.
