N2 - Aims: Atrial fibrillation (AF) is a leading cause of hospitalisations, yet little is known about 30-day readmissions following discharge despite increasing policy focus on reducing readmissions. We assessed the rate, timing, causes and predictors of 30-day unplanned readmission following an acute and elective AF hospitalisation using population-wide data. Methods: We studied all patients hospitalised for AF from 2010 to 2015 at all public and most private hospitals in Australia and New Zealand. The main outcome measures were unplanned readmissions within 30 days of discharge, primary diagnosis associated with these readmissions, and their predictors as modelled by logistic regression. Results: Among 301,654 patients hospitalised for AF (mean age 69.2±13.6 yrs 55.6% female 65.2% acute presentations), 29,750 (9.9%) experienced an unplanned readmission within 30 days with 62.6% occurring by 14 days. Unplanned readmissions occurred more frequently following an acute versus elective AF hospitalisations (12.5% vs 4.9% p<0.001). The most common diagnoses associated with readmissions were recurrence of AF (n=9,890 33.2%), and preventable conditions including heart failure (n=2,683 9.0%), pneumonia (n=724 2.4%) and acute myocardial infarction (n=510 1.7%). A higher risk of 30-day readmission was associated with congenital cardiac/circulatory defect (OR 2.18 CI 1.44–3.30), congestive heart failure (OR 1.34 CI 1.30–1.39), and arrhythmia/conduction disorders (OR 1.25 CI 1.21–1.28). Conclusion: Almost 1 in 10 AF hospitalisations resulted in unplanned readmission within 30-days, mostly for AF recurrence. Improved clinical management of AF and transitional care planning are required to reduce unplanned readmissions following AF hospitalisations.
