Real-world evidence that among atrial fibrillation patients warfarin is associated with reduced nonelective admissions compared with those on DOACs.

DOACs for AF thromboprophylaxis are associated with the increased risk of ED attendance, recurrent hospitalization, and numerical rise in ED re-attendance and first nonelective hospitalization compared to warfarin. However, these real-world data cannot establish if this difference results from medication adherence, lack of regular warfarin clinic monitoring, unmeasured confounders, or fundamental agent efficacy disparities.
