In-hospital mortality of atrial fibrillation (AF) is higher in rural hospitals than in urban hospitals, a recent study found. The cross-sectional study of patients hospitalized for AF was performed in the National Inpatient Samples between 2012 and 2014 to compared in-hospital mortality in patients admitted to urban vs rural hospitals. 248,731 admissions for AF (mean age 69 years, 78% white, 48% women) were identified. Researchers found:
- 218,946 (88%) patients were from urban hospitals and 29,785 (12%) were from rural hospitals.
- Patients admitted to rural hospitals had a 17% increased risk of death compared to those admitted to urban hospitals (OR, 1.17).
- Similar results were obtained in a propensity score-matched analysis and in subgroup analyses by sex, race, and region.
