ABSTRACT: Background
The use of transcatheter aortic valve replacement (TAVR) has grown rapidly. The purpose of this study was to assess whether hospital market competition was associated with the use of TAVR.Methods
We used 5 Healthcare Cost and Utilization Project state inpatient databases (Arizona, Florida, Iowa, Massachusetts, Washington) to identify patients undergoing TAVR (n = 5563) or surgical aortic valve replacement (n = 30,672) across 154 hospitals from 2011 to 2014. Using the Herfindahl-Hirschman Index (HHI) to calculate market competition, hospitals were categorized into commonly used categories of low (HHI >0.25), moderate (HHI 0.15-0.25), and high (HHI <0.15) competition. We associated market competition category with TAVR utilization using hierarchical logistic regres
