D-PO01-197 - Thirty Day Readmission After Ventricular Tachycardia Ablations: A Report From National Readmission Database 2016 (ID 1514)


Background: Readmissions after cardiac procedures are common and contribute to increased healthcare utilization and costs. Data on 30-day readmissions after ventricular tachycardia ablation (VTA) are limited.
Objective: To investigate the cause and rate of readmission after VTA.
Methods: Patients undergoing ventricular tachycardia between January and November 2016 who survived the index hospitalization were identified in the Nationwide Readmissions Database. Incidence, causes, and costs of 30-day readmissions were analyzed. Two-sided p-value was considered significant.
Results: Of the 9616 VTA patients, 723 (7.5 %) were readmitted within 30 days. Mean age was 65.1 years (13.9), with 39.3% female. Out of total index admission, 3351 (34.9%) were elective. Inhospital all-cause mortality during index procedure and readmission were 1.4% and 3.7%, respectively. Out of all admission, 25.4% were due to arrhythmia (7.9% VT, supraventricular tachycardia 2.1%, atrial fibrillation/flutter 10.2%, ventricular fibrillation 0.3%. Other causes of readmission were heart failure (12.5%), Sepsis (4.9%), Stroke (1.0%), renal failure (2.3%) and others (53.9%). Median length of stay and charge of readmissions were 4 days (interquartile range, 2-7 days) and $39406 (interquartile range, $19978-81317), respectively.
Conclusion: All-cause readmissions after VTA are frequent with a high early post procedure mortality- 1/100 and 3/100 patients during index and readmission respectively. Further research is needed to identify measures to prevent readmissions and associated resource utilization.
