Objective: We determined geographic access to transcatheter aortic valve replacement (TAVR) in Michigan, and compared it to the access of other invasive cardiac services; namely, percutaneous coronary intervention (PCI), non-transplant cardiac surgery, and cardiac transplant surgery. Methods: A geographic information systems analysis was performed using the 2010 U.S. Census Survey and hospital data from the state of Michigan to construct maps of service areas around hospitals providing TAVR, PCI, non-transplant cardiac surgery, and cardiac transplant surgery. Hospital service areas ranging from 5-miles to 75-miles driving distance were included in the analysis. Geographic access was calculated as the percentage of the population living within the hospital service areas providing the four types of cardiac procedures studied in this analysis. Results: A total of 15 hospitals provide TAVR in Michigan in 2015. For TAVR clinical sites, the mean number of beds, total annual discharges, and total annual patient days are 571, 28,946, and 140,859, respectively. Of the 9,883,640 persons in Michigan, 2,365,783 (23.9%) live within 5 miles, 7,856,455 (79.5%) live within 30 miles, and 9,004,943 (91.1%) live within 50 miles driving distance of a hospital offering TAVR. In general, these proportions mirror those for PCI (8,857,148 [89.6%] living within 30 miles) and non-transplant cardiac surgery (8,814,143 [89.2%] living within 30 miles), as opposed to cardiac transplant surgery (5,481,122 [55.5%] living within 30 miles) (Figure). Conclusions: Nearly 4 of 5 Michigan residents live within 30 miles driving distance of a hospital providing TAVR. Relative to other invasive cardiac services, TAVR is more similar in geographic access to PCI and non-transplant cardiac surgery than it is to cardiac transplant surgery. These findings may have implications for whether TAVR remains a highly specialized procedure or becomes a more broadly available option for aortic stenosis.
