Safety and feasibility of same-day discharge for catheter ablation of atrial fibrillation: a systematic review and meta-analysis.

Purpose: Most centers performing catheter ablation (CA) of atrial fibrillation (AF) admit the patients for an overnight hospital stay to monitor for post-procedure complications, but the clinical benefits of this overnight hospital admission policy have not been carefully investigated. We hypothesized that same-day discharge strategy is safe and feasible in patients with AF undergoing CA.
Methods: A systematic review of studies comparing the safety of same-day discharge vs hospital admission for AF patients undergoing CA was conducted in PubMed/MEDLINE, Embase, Scopus, and Web of Science. No randomized controlled trials met the inclusion criteria; therefore, observational cohort studies were included. Mantel-Haenszel risk ratios were calculated and I ² statistics were reported for heterogeneity assessment.
Results: A total of 8 observational studies with 10,102 patients were included. There were no statistically significant differences between same-day discharge vs hospital admission in all studied outcomes including post-discharge 30-day hospital visits (RR: 0.90; 95% CI: 0.40-2.02; p = 0.81), post-discharge vascular/bleeding complications (RR: 0.93; 95% CI: 0.46-1.88; p = 0.85), post-discharge stroke/transient ischemic attack/thromboembolism (RR: 0.70; 95% CI: 0.23-2.20; p = 0.55), and post-discharge recurrent arrhythmias (RR: 0.81; 95% CI: 0.60-1.09; p = 0.1).
Conclusion: In carefully selected AF patients undergoing CA, same-day discharge strategy is feasible and safe. There are no significant differences in post-discharge 30-day hospital visits, post-discharge vascular complications, and other safety outcomes. Randomized trials are needed to validate these hypothesis-generating findings.
