Short-term outcomes of atrial flutter ablation

Area of Science:

• Cardiology
• Electrophysiology
• Health Services Research

Background:

• Early readmissions post-atrial flutter (AFL) ablation impact patient quality of life and healthcare costs.
• Understanding readmission predictors is crucial for effective patient management.

Purpose of the Study:

• To identify factors associated with 90-day readmissions following AFL catheter ablation.
• To analyze common causes and predictors of readmission in AFL patients.

Main Methods:

• Utilized the National Readmission Database (2013-2014) to identify AFL patients undergoing catheter ablation.
• Employed Cox proportional and hierarchical logistic regression to determine predictors of readmission and complications.
• Analyzed readmission causes using ICD-9-CM codes.

Main Results:

• The 90-day readmission rate was 18.19%, with 50% occurring within 30 days.
• Common readmission causes included heart failure, atrial fibrillation, atrial flutter, respiratory complications, infections, and bleeding.
• Predictors of readmission included pre-existing heart failure, chronic pulmonary disease, anemia, malignancy, weekend admission, and longer length of stay (≥5 days).

Conclusions:

• Cardiac etiologies are the most frequent reasons for readmission after AFL ablation.
• Identifying high-risk individuals, meticulous discharge planning, and close post-discharge follow-up are key to reducing readmission rates.
