We identified a cohort of adult patients on hemodialysis who were newly diagnosed with atrial fibrillation (AF) in 2007-2011 and who participated in a low-income subsidy program of Medicare Part D. Index date – the 30th day after discharge from the first hospitalization with an AF diagnosis or the 30th day after a first outpatient AF diagnosis. ESRD – end-stage renal disease.
