- Millions More Uninsured Could Impact Health of Those with Insurance, Too Kaiser Health News by Julie Rovner—Much has been written lately about how individuals' health could suffer if they lose insurance under the health proposals circulating in the U.S. House and Senate. But there is another consequence: creating millions more people without insurance could also adversely affect the health of people who remain insured. "We know that communities with higher rates of uninsurance have worse access to care for those with Medicare or private insurance," said John Ayanian, director of the Institute for Healthcare Policy and Innovation at the University of Michigan. And if either of the GOP proposals under consideration becomes law, he said, "it's very likely we would go back to some of those same problems we had a decade ago with high rates of uninsurance."
