Outcomes of Hemorrhagic Stroke Patients with Atrial Fibrillation or Flutter.

Abstract

Hemorrhagic stroke is a life-threatening complication, and may be particularly prevalent in patients with atrial fibrillation/flutter (AF/AFL) due to their need for anticoagulation. We sought to estimate in-hospital mortality, length of stay (LOS) and in-patient treatment cost of patients with AF/AFL admitted with hemorrhagic stroke. We used the 2008-2011 National Inpatient Sample to identify adult AF/AFL patients with a principle discharge diagnosis of subarachnoid or intracerebral hemorrhage. Endpoints of interest included in-hospital mortality, LOS, and hospital treatment costs (2015 US$). In-hospital mortality for subarachnoid and intracerebral hemorrhage was 31.3% and 31.8%, respectively. Patients had a median LOS of 5 days and 25% of patients accrued costs in excess of $24,107/stay. Admissions for hemorrhagic stroke among patients with AF/AFL were associated with substantial in-hospital mortality and treatment costs.
