The Affordable Care Act’s (ACA) expansion of Medicaid to low-income adults is preventing thousands of premature deaths each year, a landmark study finds.[1] It saved the lives of at least 19,200 adults aged 55 to 64 over the four-year period from 2014 to 2017. Conversely, 15,600 older adults died prematurely because of state decisions not to expand Medicaid. (See Figure 1; see Table 1 for state-by-state estimates.) The lifesaving impacts of Medicaid expansion are large: an estimated 39 to 64 percent reduction in annual mortality rates for older adults gaining coverage.
... Nonetheless, the estimates show that Medicaid expansion ranks with other major public health interventions in terms of its lifesaving potential. If all states had expanded Medicaid, the number of lives saved just among older adults in 2017 would roughly equal the number of lives that seatbelts saved among the full population, based on estimates from the National Highway Traffic Safety Commission.[9] (See Figure 3.)
