Exit rates of accountable care organizations that serve high proportions of beneficiaries of racial and ethnic minority groups

Importance: The Medicare Shared Savings Program provides financial incentives for accountable care organizations (ACOs) to reduce costs of care. The structure of the shared savings program may not adequately adjust for challenges associated with caring for patients with high medical complexity and social needs, a population disproportionately made up of racial and ethnic minority groups. If so, ACOs serving racial and ethnic minority groups may be more likely to exit the program, raising concerns about the equitable distribution of potential benefits from health care delivery reform efforts. Objective: To evaluate whether ACOs with a high proportion of beneficaries of racial and ethnic minority groups are more likely to exit the Medicare Shared Savings Program and identify characteristics associated with this disparity. Design, Setting, and Participants: This retrospective observational cohort study used secondary data on Medicare Shared Savings Program ACOs from January 2012 through December 2018. Bivariate and multivariate cross-sectional regression analyses were used to understand whether ACO racial and ethnic composition was associated with program exit, and how ACOs with a high proportion of beneficaries of racial and ethnic minority groups differed in characteristics associated with program exit. Exposures: Racial and ethnic composition of an ACO\u27s beneficiaries. Main Outcomes and Measures: Shared savings program exit before 2018. Results: The study included 589 Medicare Shared Savings Program ACOs. The ACOs in the highest quartile of proportion of beneficaries of racial and ethnic minority groups were designated high-proportion ACOs (145 [25%]), and those in the lowest 3 quartiles were designated low-proportion ACOs (444 [75%]). In unadjusted analysis, a 10-percentage point increase in the proportion of beneficiaries of racial and ethnic minority groups was associated with a 1.12-fold increase in the odds of an ACO exit (95% CI, 1.00-1.25; P = .04). In adjusted analysis, there were significant associations among high-proportion ACOs between characteristics such as patient comorbidities, disability, and clinician composition and a higher likelihood of exit. Conclusions and Relevance: The study results suggest that ACOs that served a higher proportion of beneficaries of racial and ethnic minority groups were more likely to exit the Medicare Shared Savings Program, partially because of serving patients with greater disease severity and complexity. These findings raise concerns about how current payment reform efforts may differentially affect racial and ethnic minority groups

Out-Of-Network Primary Care Is Associated With Higher Per Beneficiary Spending In Medicare ACOs

Despite expectations that Medicare accountable care organizations (ACOs) would curb health care spending, their effect has been modest. One possible explanation is that ACOs’ inability to prohibit out-of-network care limits their control over spending. To examine this possibility, we examined the association between out-of-network care and per beneficiary spending using national Medicare data for 2012–15. While there was no association between out-of-network specialty care and ACO spending, each percentage-point increase in receipt of out-of-network primary care was associated with an increase of $10.79 in quarterly total ACO spending per beneficiary. When we broke down total spending by place of service, we found that out-of-network primary care was associated with higher spending in outpatient, skilled nursing facility, and emergency department settings, but not inpatient settings. Our findings suggest an opportunity for the Medicare program to realize substantial savings, if policy makers developed explicit incentives for beneficiaries to seek more of their primary care within network
