What are the rates and predictors of 30-day readmission and in-hospital complications following inpatient ventricular tachycardia catheter ablation?
Inpatient VT ablation is associated with an 8.2% in-hospital complication rate and a 16.3% 30-day readmission rate, primarily driven by recurrent VT and comorbidities like CKD and CHF.
BACKGROUND: Utilization of catheter ablation of ventricular tachycardia (VT) has steadily increased in recent years. Exploring short-term outcomes is vital in health care planning and resource allocation. METHODS: The Nationwide Readmissions Database from 2010 to 2014 was queried using the ICD-9 codes for VT (427.1) and catheter ablation (37.34) to identify study population. Incidence, causes of 30-day readmission, in-hospital complications as well as predictors of 30-day readmissions, complications, and cost of care were analyzed. RESULTS: Among 11 725 patients who survived to discharge after index admission for VT ablation, 1911 (16.3%) were readmitted within 30 days. Paroxysmal VT was the most common cause of 30-day readmission (39.51%). Dyslipidemia, chronic kidney disease (CKD), previous CABG, congestive heart failure (CHF), chronic pulmonary disease, and anemia predicted increased risk of 30-day readmissions. The overall in-hospital complication rate was 8.2% with vascular and cardiac complications being the most common. Co-existing CKD and CHF and the need for mechanical circulatory support (MCS) predicted higher complication rates. Similarly increasing age, CKD, CHF, anemia, in-hospital use of MCS or left heart catheterization, teaching hospital, and disposition to nursing facilities predicted higher cost. CONCLUSION: Approximately one in six patients was readmitted after VT ablation, with paroxysmal VT being the most common cause of the readmission. A complication rate of 8.2% was noted. We also identified a predictive model for increased risk of readmission, complication, and factors influencing the cost of care that can be utilized to improve the outcomes related to VT ablation.
Sharma et al. (Fri,) conducted a observational in Ventricular tachycardia (n=11,725). Catheter ablation was evaluated on 30-day readmission. Inpatient ventricular tachycardia catheter ablation was associated with a 30-day readmission rate of 16.3% and an overall in-hospital complication rate of 8.2%.
