Performance in the Medicare Shared Savings Program by accountable care organizations disproportionately serving dual and disabled populations.
The purpose of this study was to examine performance by accountable care organizations (ACOs) in the top quintile of their proportion of beneficiaries who were dually enrolled in Medicare and Medicaid (high-dual), and the top quintile of disabled beneficiaries (high-disabled). Measures used were quality scores, savings per beneficiary, whether or not the ACO shared savings and the amount of shared savings. The researchers found that high-dual and high-disabled ACOs had similar or higher spending than other ACOs at baseline, but achieved greater savings and were equally or more likely to earn shared savings; alternative payment models can have positive financial outcomes for providers serving vulnerable populations.

Association between Medicare accountable care organization implementation and spending among clinically vulnerable beneficiaries.
The purpose of this cohort study was to examine the effect of Medicare accountable care organization (ACO) contracts on both spending and high-cost institutional utilization for all Medicare beneficiaries and for clinically vulnerable beneficiaries. The main outcomes and measures for this study were total spending per beneficiary-quarter, spending categories, utilization of hospitals and emergency departments, ambulatory care sensitive admissions, and 30-day readmissions. The study found that total spending decreased by $34 per beneficiary-quarter after implementation of ACO contracts across the overall Medicare population and decreased $114 in clinically vulnerable patients. In the overall Medicare cohort, hospitalizations and emergency department visits decreased by 1.3 and 3.0 events per 1000 beneficiaries per quarter, respectively. Hospitalizations and emergency department visits decreased in the clinically vulnerable cohort by 2.9 and 4.1 events per 1000 beneficiaries per quarter, respectively. Variations in total spending related with ACOs did not differ by clinical condition of beneficiaries.
