The Effects of Medicaid Expansion under the ACA: Findings from a Literature Review

The three appendix tables support the Kaiser Commission on Medicaid and the Uninsured brief titled, “The Effects of Medicaid Expansion under the ACA: Findings from a Literature Review.” Each table corresponds to one of the three sections in the brief (Medicaid expansion’s impacts on coverage; access to care, utilization, and health outcomes; and economic outcomes). The tables provide additional details on the focus of and major findings from each individual Medicaid expansion study. Within each table, nationwide studies are displayed first followed by multi-state and then single state studies. Within those groupings, studies are listed in reverse chronological order (most recent first). Studies with findings that apply to multiple sections are included in more than one table or table sub-section.

Studies were selected for this literature review based on several specific criteria, all intended to preserve the project’s focus on direct effects of Medicaid expansion under the Affordable Care Act (ACA). These tables include peer-reviewed studies, free-standing reports, government reports, and white papers published between January 2014 and May 2016 using data from 2014 or later. The brief also includes only studies that report specific impacts of expansion and excludes studies or findings on impacts of ACA coverage expansions generally (not specific to Medicaid expansion alone), studies investigating potential effects of expansion in states that have not (or had not, at the time of the study) expanded Medicaid, and studies published by advocacy organizations.
