Learning Systems for Accountable Care Organizations

2013-2020
Prepared For

U.S. Department of Health and Human Services, Center for Medicare & Medicaid Innovation

Under a contract with the Centers for Medicare & Medicaid Services (CMS) Innovation Center, Mathematica operated multiple learning systems for Medicare accountable care organizations (ACOs) to promote the rapid distribution of innovative ideas and strategies for improving health care delivery and quality.

ACOs consist of doctors, hospitals, and other health care providers who work together to deliver coordinated, high quality care to Medicare beneficiaries. These organizations accept responsibility not only for the quality of care but also for the cost of care, and they provide data to CMS so that the agency can assess their performance. ACOs that efficiently deliver high quality care receive from CMS some of the savings that they generated for the Medicare program.  

Between 2013 and 2021, Mathematica helped the CMS Innovation Center accelerate the dissemination of innovative strategies for improving quality while reducing costs by operating learning systems for Medicare ACOs. Mathematica and its partners—HCMDM, the Institute for Healthcare Improvement, and Premier, Inc.—operated distinct learning systems for different types of ACOs. In 2019, the ACOs included those who are participating the Next Generation ACO Model; the Comprehensive End-Stage Renal Disease Care Model; the Vermont All-Payer ACO Model; and the Medicare Shared Savings Program, which includes ACOs who are participating in the Track 1+ Model and the Pathways to Success Program. Previously, Mathematica also supported the Pioneer ACO, Advanced Payment, and ACO Investment Models.
