Abstract

BACKGROUND: Understanding the factors associated with early readmissions following atrial flutter (AFL) ablation is critical to reduce the cost and improving the quality of life in AFL patients.

METHOD: The study cohort was derived from the National readmission database 2013-14. International Classification of Diseases, 9th Revision (ICD-9-CM) diagnosis code 427.32 and procedure code 37.34 were used to identify AFL and catheter ablation respectively. The primary and secondary outcomes were 90-day readmission and complications including in-hospital mortality. Cox proportional regression and hierarchical logistic regression were used to generate the predictors of primary and secondary outcomes respectively. Readmission causes were identified by ICD-9-CM code in primary diagnosis field of readmissions.

RESULT: Readmission rate of 18.19% (n = 1010 with1396 readmissions) was noted among AFL patients (n = 5552). Common etiologies for readmission were heart failure (12.23%), atrial fibrillation (11.13%), atrial flutter (8.93%), respiratory complications (9.42%), infections (7.4%), bleeding (7.39%, including GI bleed - 4.09% and Intracranial bleed - 0.79%) and stroke/TIA (1.89%). Multivariate predictors of 90-day readmission (Hazard ratio, 95% confidence interval, p-value) were preexisting heart failure (1.30, 1.13-1.49, p

CONCLUSION: Cardiac etiologies remain the most common reason for the readmission after AFL ablation. Identifying high risk patients, careful discharge planning and close follow-up post-discharge can potentially reduce readmission rates in AFL ablation patients.
