MedPAC Cites Dobson | DaVanzo's ACO Study in June Report

Published Monday, July 22, 2019

The Medicare Payment and Advisory Commission (MedPAC) has cited the Dobson | DaVanzo evaluation of Medicare Shared Savings Program (MSSP) Accountable Care Organizations (ACOs) (funded by NAACOS) in its June 2019 report. Within the report, MedPAC corroborates the overall savings level described in our report. MedPAC carefully describes and compares a variety of recent evaluations from the literature, including those from Harvard, University of Michigan, the National Institutes of Health, NORC, and Dobson | DaVanzo.

As noted in our study of MSSP and elsewhere in the literature, ACO programs are fiendishly difficult to evaluate. This is part of the nature of voluntary provider-driven programs: they are in some part driven by an inherent bias of providers deciding to be in the program. This, coupled with retrospective patient assignment rules and rapidly shifting ACO provider rolls, can make for a program where almost every measurable aspect shifts over time (chiefly which providers and patients are included).

We look forward to continuing the public discussion of the impact of this important program and contributing further to the literature.
