The role of differing levels of frailty in choice of oral anticoagulants for older adults with atrial fibrillation (AF) remains unclear. To examine the outcomes of direct oral anticoagulants (DOAC) versus warfarin by frailty levels 1:1 propensity score-matched analysis of Medicare data, 2010-2017 Community Medicare beneficiaries with AF who initiated dabigatran, rivaroxaban, apixaban, or warfarin Composite endpoint of death, ischemic stroke, or major bleeding by frailty levels, defined by a claims-based frailty index In the dabigatran-warfarin cohort (n=158,712; median follow-up, 72 days), the event rate (per 1,000 person-years) was 63.5 for dabigatran-initiators and 65.6 for warfarin-initiators (hazard ratio [HR], 0.98 [95% CI: 0.92, 1.05]; rate difference [RD], −2.2 [−6.5, 2.1]). For non-frail, pre-frail, and frail groups, HRs were 0.81 (0.68, 0.97), 0.98 (0.90, 1.08), and 1.09 (0.96, 1.23), respectively. In the rivaroxaban-warfarin cohort (n=275,944; median follow-up, 82 days), the event rate (per 1,000 person-years) was 77.8 for rivaroxaban-initiators and 83.7 for warfarin-initiators (HR, 0.98 [0.94-1.02]; RD, −3.9 [−10.3, 2.4]). For non-frail, pre-frail, and frail groups, HRs were 0.88 (0.77, 0.99), 1.04 (0.98, 1.10), and 0.96 (0.89, 1.04), respectively. In the apixaban-warfarin cohort (n=218,738; median follow-up, 84 days), the event rate (per 1,000 person-years) was 60.1 for apixaban-initiators and 92.3 for warfarin-initiators (HR, 0.68 [0.65, 0.72]; RD, −32.2 [−36.1, −28.3]). For non-frail, pre-frail, and frail groups, HRs were 0.61 (0.52, 0.71), 0.66 (0.61, 0.70), and 0.73 (0.67, 0.80), respectively. Residual confounding, lack of clinical frailty assessment For older adults with AF, apixaban was associated with lower rates of adverse events across all frailty levels. Dabigatran and rivaroxaban were associated with lower event rates only among non-frail patients. National Institute on Aging
