Effect of Antiarrhythmic Drug Initiation on Readmission After Catheter Ablation for Atrial Fibrillation
چکیده انگلیسی

ObjectivesThis study sought to evaluate the impact on antiarrhythmic drug (AAD) initiation on the risk of readmission after catheter ablation for atrial fibrillation (AF) among patients not already treated with an AAD.BackgroundHospital readmission, a commonly tracked indicator of quality and efficiency of care delivery, occurs in about 15% patients within 90 days of undergoing catheter ablation for AF.MethodsUsing a large national administrative claims database, we identified all atrial fibrillation patients (≥18 years of age) who underwent catheter ablation between January 2005 and December 2013 (n = 7,442). We identified the subset of patients who had not been on an AAD in the 90 days before ablation (n = 2,542) and, among those, the patients in whom an AAD was initiated at discharge following the ablation (n = 519).ResultsThe readmission rate was significantly lower among patients who were initiated on an AAD compared with those who were not (11.6% vs. 16.2%, p = 0.009). The association persisted after adjustment for age, sex, Charlson index, and CHADS2 score (hazard ratio [HR]: 0.73, 95% confidence interval [CI]: 0.56 to 0.97; p = 0.03). In unadjusted time to event analysis, amiodarone (HR: 0.55, 95% CI: 0.32 to 0.94; p = 0.039) was associated with the greatest reduction in readmission whereas dronedarone, Class II agents, and Class IC agents had no statistically significant effect on readmission. AADs were discontinued in 44.5% of patients at 3 months.ConclusionsInitiation of an AAD at discharge of catheter ablation is associated with a significant reduction in readmission within 90 days. Routine initiation of an AAD after catheter ablation may reduce healthcare utilization in the periablation period; however, the high rate of medication discontinuation may suggest that side effects or inefficacy may limit long-term AAD use post-ablation.
