About OMAS

The Ohio Medicaid Assessment Survey (OMAS) is an Ohio-specific assessment that provides health care access, utilization, and health status information about residential Ohioans at the state, regional and county levels, with a concentration on Ohio’s Medicaid, Medicaid-eligible, and non-Medicaid populations. The OMAS mission is to assist the efficient and effective administration of Ohio’s Medicaid program.  

OMAS is a mail, web, and random digit dial telephone survey that first fielded in 1997. In its eighth iteration, OMAS enables tracking of the state’s health system and health status over time.

The main topics for OMAS are health care access, health care utilization, insurance status, chronic and acute health conditions, mental health, health risk behaviors, and health demographics such as employment, income, and socioeconomic indicators. These topics assist the Ohio Department of Medicaid and other health-associated state and local agencies in identifying health services and system gaps and assist in developing strategies for improving health services to Ohio’s population.

OMAS is widely used for health system research and program development by Ohio’s colleges and universities, state and local governments, private sector organizations, and policy makers. OMAS data have been used for grant applications, community health initiatives, academic publications and presentations, health system planning activities, and philanthropic activities. These uses comply with the OMAS project’s purpose to serve Ohio’s Medicaid population and the state’s health vulnerable populations.

OMAS is administered by an Executive Committee which holds representation from Ohio’s health-associated state agencies, academics, and health stakeholders, and is fielded with the assistance of the Research Triangle Institute (RTI), International. If you have been contacted to complete this important survey and have questions or concerns, please contact either RTI at 1-855-322-2826, or the State of Ohio at 1-800-678-6437.
