Better care, lower costs: Michigan Medicine leading the way

U-M has been at the national forefront of one of the most important trends in medicine today: population health.

This quest for better care quality, better health for entire populations, and lower health care costs will only increase in importance in coming years.

We got in on this trend on the ground floor, by participating in a Medicare demonstration project that began in 2005 and became the prototype for the Accountable Care Organization (ACO) movement. We have also played leadership roles in efforts funded by private insurers and state agencies.

We have formed two ACOs, and helped launch a statewide patient-centered medical home effort. Below, you'll find more about each of these efforts and more.

In a Jan. 2, 2013 letter to JAMA, two Dartmouth researchers wrote, "If all institutions behaved like the University of Michigan under the system of ACOs, the potential savings would be enormous."


In 2016, leaders of our effort published an overview of our involvement in population health in the American Journal of the Medical Sciences,

The forerunner of ACOs:
Medicare Physician Group Practice (PGP) Demonstration Project

Summary of JAMA paper: independent analysis of project results (Sept. 2012, Dartmouth)

JAMA paper - 2012;308(10):1015-1023. doi:10.1001/2012.jama.10812

Summary of final results (Aug. 2011)

Fast facts: Involved all 1,700+ members of the U-M Faculty Group Practice and thousands of Medicare fee-for-service patients. U-M was one of 10 PGPs to take part nationally, and one of only 2 that both met quality goals and reduced costs. More than $22M in Medicare spending saved, highest savings seen in dual-eligible (Medicare/Medicaid) patients.

Fast facts: POM ACO Involves nearly 6,000 physicians and other providers from physician groups across Michigan, and over 77,500 Medicare fee-for-service patients


Patient-centered medical home initiative: MiPCT



Transition to State Innovation Model for Patient Centered Medical Home

Fast facts: Three-year multi-payer project involving 500+ primary care practices & 1,800 primary care physicians affiliated with 41 physician/physician hospital organizations (POs/PHOs). UMHS is the project manager and the Michigan Department of Community Health is the lead oversight agency. Ended December 2016, with a transition to a State Innovation Model funded by a federal grant to the state of Michigan.



Organizations within UMHS involved in population health:

The Faculty Group Practice, part of the Medical School, serves as the physician organization for all 2,000+ U-M faculty physicians, who care for patients at the U-M Hospitals & Health Centers, the VA Ann Arbor Healthcare System, and select partner locations. Founded in 1996, the FGP manages the UMHS ambulatory care network of health centers in Ann Arbor and surrounding communities. It has a longtime commitment to efforts to improve quality of care, and reports a number of its own clinical quality and patient rating measures publicly via the UMHS Quality & Safety site.

The Population Health Office was created in January 2012 to manage the various population-based patient care delivery, quality improvement and reimbursement pilot programs in which the UMHS Faculty Group Practice (FGP) participates.  The office collaborates with the FGP Quality Management Program, and Ambulatory Care Services, as well as local and regional providers to develop and provide innovative ways to better deliver high quality, efficient care to specific UMHS patient populations.

The Complex Care Management Program was formed in 2005 to coordinate care for UMHS patients with the highest level of need, including physical illnesses, mental illness, homelessness, and lack of adequate health insurance.  To date, the program has seen drastic reductions in hospital admissions, ER visits, and total costs for this specific population of patients. 

The Michigan Care Management Resource Center assists and supports Michigan primary care and specialty practices as they build upon their current Patient Centered Medical Home (PCMH) and PCMH – Neighbor (PCMH-N) capabilities.
