Keeping cost from getting in the way of stroke prevention

People who survive a stroke in their 40s, 50s or early 60s may still have decades to live—but only if they take blood thinners, blood pressure drugs and other medications that can reduce their risk of a second stroke.

If they don’t have insurance and money to cover the cost of those medications, though, they might stop taking them—and their risk of another stroke will spike. And if they suffer another one, it will probably cause much more disability than the first—and cost much more to treat than the cost of the medications that could have prevented it.

Now, a new study shows what happened when more young stroke survivors got access to health insurance after the federal Affordable Care Act took effect. A lot of the credit may go specifically to the decision by a majority of states to let more people enroll in Medicaid.

In all, the ACA and Medicaid expansion stopped a trend that had been climbing for years: More and more stroke survivors under age 65 lacking insurance and reporting they didn’t take their medications due to cost.

After the ACA’s insurance programs went into effect in 2014, both trends reversed rapidly, the study shows. Where once nearly 1 in 4 younger stroke survivors said cost had gotten in the way of their medication use, the number dropped to 18 percent. Meanwhile, among stroke survivors over age 65, who had access to Medicare, not much changed in either insurance status or cost-related non-adherence, as it’s called.

Deborah A. Levine, M.D., MPH, led the University of Michigan team that did the analysis, and published it in JAMA Neurology. She runs a clinic for stroke survivors at U-M’s Frankel Cardiovascular Center, part of Michigan Medicine.

“What’s exciting about these findings is that they show that the ACA was effective at increasing insurance and decreasing cost-related non-adherence to medication among stroke survivors younger than 65 in the United States, suggesting that further expansion of Medicaid to additional states would have a larger impact and help stroke survivors in those states,” she says.

Her own experience treating stroke patients in Michigan—which expanded Medicaid in spring of 2014—prompted Levine to team with colleagues to study national data collected by the Centers for Disease Control and Prevention.

“Before expansion, many of the younger patients who I saw after a stroke were unable to afford their medication—and that contributed to their first stroke. So we would work hard to try to help them find ways to get affordable medication to reduce the risk of another stroke,” says Levine, who is an associate professor internal medicine and neurology at the U-M Medical School and a member of the U-M Institute for Healthcare Policy and Innovation. “Now, more of my patients are qualifying for Medicaid, and so have greater access to stroke preventive medications.”

In all, nearly 31 percent of all stroke survivors ages 45 to 64 in the new study were covered by Medicaid in 2014 to 2016, up from 24 percent in 2011 to 2013.

But Levine cautions that Medicaid expansion—which is under consideration in three states and not enacted in 14 states—will reduce but not solve the problem of stroke survivors being unable to afford medications.

Many stroke survivors still struggle to afford their medications because they don’t have insurance or their insurance shifts more of the costs of medications to patients. These stroke survivors are still vulnerable.

“All stroke survivors need affordable insurance and prescription drug coverage,” says Levine. “In addition, they need affordable drug prices and co-payments to get the medications they need and prevent another stroke.”
