The Effects of Market Competition on Cardiologists' Adoption of Transcatheter Aortic Valve Replacement.

ABSTRACT:

Background

For decades, the prevailing assumption regarding the diffusion of high-cost medical technologies has been that competitive markets favor more aggressive adoption of new treatments by health care providers (ie, the "Medical Arms Race"). However, novel regulations governing the adoption of transcatheter aortic valve replacement (TAVR) may have disrupted this paradigm when TAVR was introduced.

Objective

The objective of this study was to assess the relationship between the market concentration of physician group practices and the adoption of TAVR in its first years of use.

Research design

This was a retrospective cohort study.

Subjects

Physician group practices (n=5116) providing interventional cardiology services in the United States from May 1, 2012,
