Abstract

Objective: To understand the current role of urologists in Medicare Shared Savings Program (MSSP) Accountable Care Organizations (ACOs) and the organizational characteristics of ACOs with participating urologists.

Materials and methods: Using 2012-2013 Medicare data and the National Provider Identifier Database, we classified each urologist in the U.S. and Puerto Rico as either an MSSP ACO participant or nonparticipating provider. We then examined the distribution of ACO-participating urologists across the U.S. and among the first 220 MSSP ACOs. We also compared the characteristics of ACOs with and without participating urologists.

Results: Among 11,084 identified urologists, 1118 (10%) were MSSP ACO participants. ACO-participating urologists practiced more frequently in the Northeast and Midwest (P < .001), and were more commonly female (10% vs 8%, P = .003). At an organizational level, only 110 (50%) of the initial MSSP ACOs included at least one urologist; among this group, the number of participating urologists ranged from 1 to 55. ACOs with one or more participating urologist were larger organizations, with respect to both the number of assigned beneficiaries and the number of providers per 1000 beneficiaries (P < .001 for each comparison). The patient populations served by ACOs with and without urologists were similar (P > .05 for each comparison).

Conclusion: A modest percentage of urologists participate in MSSP ACOs, although many of these organizations still lack any formal involvement by urological surgeons. Without such participation, improving the coordination, quality, and cost of urologic care for Medicare beneficiaries may be more challenging.
