Abstract 152: Adherence to Rivaroxaban versus Apixaban Among Patients With Atrial Fibrillation: Analysis of Overall Population and Subgroups of Prior Oral Anticoagulant Users
Circulation-cardiovascular Quality and Outcomes(2017)
Abstract
Background: Medication nonadherence predicts poor outcomes among patients with non-valvular atrial fibrillation (NVAF). Understanding differences in adherence rates among non-vitamin K oral anticoagulants (NOACs) could guide treatment decisions, promote adherence and improve clinical outcomes. Objective: To compare adherence to rivaroxaban and apixaban among the overall NVAF population and subgroups at higher risk for adverse clinical outcomes (e.g., prior OAC use, multiple comorbidities, and with risk factors for nonadherence). Methods: Using healthcare claims from the Truven Health Analytics MarketScan database from 7/2012-7/2015, adult patients with 2 dispensings of rivaroxaban or apixaban at least 180 days apart, with u003e 60 days of supply, ≥ 6 months of pre- and post-index eligibility, ≥ 2 atrial fibrillation diagnoses pre- or post-index, and without valvular involvement were identified. Propensity score methods were used to create matched cohorts of rivaroxaban and apixaban patients, adjusting for dem...
