Policy-Focused Impact.

A new study led by Renu Tipirneni, M.D., M.Sc., assistant professor of internal medicine, and published in the journal Psychiatric Services, found expanding Medicaid to more low-income adults helped many of them feel healthier, and do a better job at work or a job search, in just one year after they got their new health coverage.

But people with behavioral health conditions, including mental health disorders such as depression or addiction to alcohol or drugs, got an especially big boost in many health and work-related measures, the study shows.

New study find expanding Medicaid means health problems get found and health improves

Nearly one in three low-income people who enrolled in Michigan's expanded Medicaid program discovered they had a chronic illness that had never been diagnosed before, according to a new study. 

And whether it was a newly found condition or one they'd known about before, half of Medicaid expansion enrollees with chronic conditions said their overall health improved after one year of coverage or more. Nearly as many said their mental health had improved.

The Latest

Traditional Medicare spends much more on post-hospital care for people in their 60s than private insurance. But the additional spending doesn't keep patients from ending up back in the hospital, finds a new study led by Scott Regenbogen, M.D., M.P.H., which used data from hospitals in the statewide Michigan Value Collaborative.


A study of Medicare HMO participants whose insurance covers part of hearing aid cost reveals disparities in use and difference in incidence of major conditions after three years. The study was led by Elham Mahmoudi, Ph.D., M.B.A., M.S.


A new study led by Sean Esteban McCabe, Ph.D., M.S.W., M.A., shows that the frequency and age at which older teens and young adults misuse prescription drugs are two predictors of substance use disorders later in life, especially alcohol misuse.


Geoff Barnes, M.D., M.Sc., is a cardiologist and a vascular medicine specialist at Michigan Medicine, and a health services researcher who is passionate about improving the safety of medication care.

"We know that medication-based treatment is effective for people with an opioid use disorder, even in reducing mortality, but many people do not receive these treatments. Much of the barrier lies in access and limited numbers of trained providers, but the picture is also more complex. It is critical to understand how addiction treatment is delivered in the U.S. in order to improve it."
