The purpose of this study was to explore the experience and perspectives of Medicaid providers in Missouri and the factors that make them more or less likely to take on new Medicaid patients following expansion. The team drew on rich, original data from interviews with primary care providers, specialists, and dentists in rural Missouri conducted during the first phase of the study to develop a quantitative survey for providers across the state. Key themes from interviews showed that participants had generally favorable views about Medicaid expansion and increased access to healthcare, though they were concerned about capacity within their practice and the health care workforce. Participants also reported challenges working with the Medicaid program, challenges treating Medicaid patients, and having received little formal training on Medicaid or expansion. The goal of the survey phase of this study was to elaborate on these themes for both rural and non-rural Missouri providers.
