D-PO01-193 - Temporal Trends Of Emergency Department Visits Of Patients With Atrial Fibrillation: A Nationwide Population-based Study (ID 960)

 E. Choi: Nothing relevant to disclose.


Background: The prevalence of atrial fibrillation (AF) is increasing, leading to an increase in the healthcare burden.
Objective: We aimed to describe temporal trends in emergency department (ED) visits of patients with AF over 12 years.
Methods: A repeated cross-sectional cohort of ED visits in patients with AF was conducted using the Korean nationwide claims database between 2006 and 2017. We identified patients who had ≥1 ED visits each year. The prevalence of ED visits, patients’ characteristics, cause of ED visit, and clinical outcomes were evaluated.
Results: During the study period, 30% of AF patients attended the ED at least once in a year, and the annual numbers continuously increased (Figure A). The mean age and CHA2DS2-VASc scores of AF patients who attended ED progressively increased, and oral anticoagulant prescription rate increased over time (29.5% to 59.5%). The most common cause of ED visits was cerebral infarction. After the ED visit, 65% to 75% of patients were subsequently hospitalized. Although patients had a higher risk profile over time, the 30-day and 90-day mortality after ED visit decreased from 2006 to 2017 (Figure B). ED visits due to ischemic stroke, intracranial hemorrhage, and myocardial infarction decreased, whereas ED visits due to AF, gastrointestinal bleeding, and other major bleeding slightly increased among total AF population over 12 years (Figure C).
Conclusion: A substantial proportion of patients with AF attended ED every year, and the annual numbers of AF patients who visited the ED significantly increased over 12 years. Optimized management approaches in a holistic and integrated manner should be provided to reduce ED visits of AF patients.
