Abstract 17425: Utilization of Radiofrequency Catheter Ablation for Treatment of Atrial Fibrillation in United States
INTRODUCTION: Utilization of radiofrequency catheter ablation (RFA) for treatment of atrial fibrillation (AF) is increasing.It is increasingly being performed outside of the specialized centers . The aim of our study was to investigate the trends in utilization of catheter ablation for AF in the United States from 2000 through 2008.
METHODS: This was a cross sectional study using the Nationwide Inpatient Sample (NIS) database. AF as primary discharge diagnosis was identified with appropriate International Classification of Diseases, IX edition codes. Patients undergoing catheter ablation for AF from 2000-2008 were included. Patients profile, characteristics pertaining to the facility, costof care, disposition, and trends over the study period were recorded. Trends in catheter ablation were analyzed for a variety of demographic attributes using Stata IC 11.0 (Stata-Corp, College Station, TX).
RESULTS: 47255 patients were identified in the NIS database that had undergone catheter ablation for AF from 2000-2008. Overall, the number of procedures increased from 2000 to 2008 with a relative percent increase of 12.6. This trend was seen among all age groups, gender and ethnicities. At any given year, age group 50-64 years and 65-79 years had maximum number of procedures compared to rest of the age group. 68.4% were male and 31.6% were female. Most of the procedures (71.1%) were performed in patients with minimum comorbidities. Private insurance (60.2%) and Medicare (34.5%) constituted the major primary expected payer for these procedures. The mean length of stay was 2.5 days , total cost of hospitalization associated with AF ablation doubled between 2000 to 2008 adjusted to infaltion dollar of the year 2000.
CONCLUSION: Catheter ablation procedures for AF have increased exponentially from 2000 to 2008. This trend was seen among all age groups, gender and ethnicities. The procedure is performed predominantly in teaching and large sized hospitals . This is the first study to evaluate utilization of atrial fibrillation abaltion procedure in United States across all insurances.
