Nationwide Adult Medicaid Consumer Assessment of Healthcare Providers and Systems

In fall 2014, the Center for Medicaid and CHIP Services (CMCS) conducted a Nationwide Adult Medicaid (NAM) Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey of Medicaid enrollees to attain national and state-by-state measures of access, barriers to care, and experiences with care across delivery systems and major population subgroups. The survey interviewed a representative sample of adults ages 18 and older enrolled in Medicaid during October through December 2013. This first-of-its kind survey provides baseline information on the experiences of low-income adults prior to a state’s expansion of coverage to the new adult group that took effect on January 1, 2014. These data will be used to inform the Centers for Medicare & Medicaid Services and state efforts to improve health care delivery for Medicaid enrollees.
