Three-Year Impacts of the Affordable Care Act: Improved Medical Care and Health Among Low-Income Adults

The following comes from a Commonwealth Fund summary of research first published in Health Affairs Web.


Synopsis
Low-income adults in Arkansas and Kentucky who obtained coverage under the Affordable Care Act’s Medicaid expansion had better access to primary care and preventive health services, lower out-of-pocket costs, improved medication compliance, and improved self-reported health status than did low-income adults in Texas, which did not expand Medicaid. Among adults with chronic conditions, ACA coverage was associated with better disease management and medication compliance and a significant increase in self-reported health status.

The Issue
Congress is currently weighing the future of the Affordable Care Act. Since becoming law, the ACA has helped more than 20 million Americans enroll in health insurance coverage, and national studies have noted improvements in coverage, consumer satisfaction, and access to care. In this Commonwealth Fund–supported study, researchers compared Kentucky, which expanded Medicaid as prescribed by the ACA; Arkansas, which obtained a waiver to use federal Medicaid funds available through the ACA to purchase private marketplace insurance for low-income adults; and Texas, which did not expand Medicaid coverage. Looking at these three states, the authors assessed ongoing changes in health care use and self-reported health among low-income adults, including those with chronic conditions, after three full years of the ACA’s coverage expansions.

Key Findings

  • By the end of 2016, the uninsured rate in Arkansas and Kentucky—the two expansion states—had dropped by more than 20 percentage points compared to Texas, the nonexpansion state. In 2016, the uninsured rate was 7.4 percent in Kentucky, 11.7 percent in Arkansas, and 28.2 percent in Texas.
  • Low-income adults in Kentucky and Arkansas who gained coverage experienced a 41-percentage-point increase in having a usual source of care, a $337 reduction in annual out-of-pocket costs, and a 23-point increase in the share of those who reported they were in “excellent” health.
  • Results were similarly positive for people with chronic illnesses who gained coverage because of the ACA. Low-income patients with diabetes, heart disease, hypertension, and stroke who gained coverage were 56 points more likely to report having regular care for their condition than were chronically ill adults in Texas, 51 points less likely than those in Texas to skip medications because of the cost, and 20 points more likely to report being in excellent health.
