Hospital-physician integration and clinical volume in traditional Medicare.
The purpose of this study was to test the effect of hospital-physician integration on primary care physicians' (PCP) clinical volume in traditional Medicare. The researchers identified 70,000 PCPs, some of whom remained non-integrated and some who became hospital-integrated during this study period. An event study design was utilized to identify the effect of integration on key measures of physicians' clinical volume, including the number of claims, work-relative value units (RVUs), professional revenue generated, number of patients treated, and facility fee revenue generated. The study found that per-physician clinical volume declined by statistically and economically significant margins. Relative to the comparison group who remained non-integrated, work RVUs fell by 7%; the number of patients treated fell by 4%; and claims volume among PCPs who became hospital-integrated fell by over 15%.

ACO awareness and perceptions among specialists versus primary care physicians: a survey of a large Medicare Shared Savings program.
This research letter describes a survey that was conducted to compare accountable care organization (ACO) awareness and perceptions among specialists versus primary care physicians (PCPs). The survey was administered in 2018 to clinicians in the Physician Organization of Michigan ACO, which was the largest Medicare Shared Savings Program (MSSP) in Michigan and among the ten largest nationally at the time. The analysis focused on 1022 non-pediatrician physician respondents practicing within 10 provider organizations. Physician respondents included PCPs (23%) and specialists (77%). The most common specialty was internal medicine (20%), followed by surgeons (14%). Specialists were less likely to be aware of ACO participation and incentives. They were also 25% less likely to know they were in an ACO compared to PCPs. In addition, specialists were 18% less likely to know their ACO was accountable for both spending and quality or that their ACO had lowered spending in the previous year. This difference in perception may help to explain ACOs’ modest impact on spending and quality.
