Republican members of the Senate announced alternatives to the Affordable Care Act today. U-M has experts who can weigh in.

John Ayanian, director of the Institute for Healthcare Policy and Innovation, the Alice Hamilton Professor of Internal Medicine and professor of public health and public policy, is a long-time researcher on how access to health insurance affects individuals' access to health care, the quality of care they receive and their health outcomes. He leads IHPI's federally approved objective evaluation of the Healthy Michigan Plan, the expansion of Medicaid under the Affordable Care Act. The evaluation recently found that Michigan's expansion of Medicaid health insurance coverage has boosted the state's economy and budget, and will continue to do even as the state assumes more of the cost of caring for the 638,000 Michiganders who have signed up for the program. Read a news release on those findings.

Sue Anne Bell, clinical associate professor in the U-M School of Nursing. Bell focuses on health outcomes in relationship to emergencies and acute care, with an eye towards affecting policy change, particularly in terms of health disparities.

“The repeal of the ACA will have tremendous negative impacts on the health of low-income populations, who are already more likely to have ill health due to poverty. The ACA allowed millions of Americans access to health insurance, with undeniably positive results. For example, a recent study showed that children on Medicaid had better health outcomes as adults, including lower rates of death and disability, as well as higher incomes (which means less use of government benefits). With close to 20 million Americans expected to lose health insurance if the repeal passes, we stand to lose the progress we have made in health and health outcomes for Americans who need health care the most.”

Laura Gultekin, assistant professor in the U-M School of Nursing, works with low resource families through research and clinical practice. She can discuss the huge decline in the numbers of people who've needed free care at clinics before and after the ACA.

"The Affordable Care Act provided families who were working in low-wage, no-benefit jobs the opportunity to enroll in insurance and access the primary and specialty care services they needed to maintain and improve their health. I anticipate a repeal of the ACA will result in loss of insurance for many of those families, whether because they remain ineligible for benefits from their employers, or because they've now been identified as having pre-existing conditions."
