Abstract

Catheter ablation of atrial fibrillation (CAF) is increasingly being used in the United States. This study aimed to identify variations in CAF use among Medicare beneficiaries (MBs) over a 6-year period (2013 to 2019). Using the Center of Medicare and Medicaid Services database, a 100% sample of MBs who underwent CAF from 2013 to 2019 was included. We stratified CAF use data geographically (Northeast, South, West, and Midwest) and identified the number of CAFs per 100,000 MBs, number of electrophysiologists performing CAFs per 100,000 MBs, number of CAFs per individual electrophysiologist, and average submitted charge for CAF. In addition, we stratified the data per urban versus rural areas and gender of the operator. We found that the mean atrial fibrillation (AF) prevalence, rates of CAFs, number of electrophysiologists performing CAFs, and number of CAFs per electrophysiologist have increased steadily in all regions. The mean AF prevalence was different among regions, with the highest prevalence in the Northeast (p <0.001); however, there was a pattern of higher CAFs rates in the West and the South (p ≥0.057). The number of electrophysiologists performing CAFs was not different among regions; however, the number of CAFs per electrophysiologist was higher in the West and the South (p <0.001). The average submitted charge for CAF has decreased over years and was the lowest in the West and the South (p <0.001). There was no major difference in these variables regarding operator gender. In conclusion, there are significant variations in CAF use among MBs in the United States according to geographic and urban versus rural regions. These variations have the potential to impact the outcomes in MBs diagnosed with AF.
