Ohio Medicaid Assessment Survey (OMAS)
The Ohio Medicaid Assessment Survey (OMAS) is a representative survey that collects 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 began fielding in 1997. The main topics include 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. The longevity of the survey enables tracking of the state's health system and population health status over time.
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 policymakers. OMAS data have been used for grant applications, community health initiatives, academic publications and presentations, health system planning activities, and philanthropic activities.
OMAS is overseen by an Executive Committee which includes representation from Ohio’s health-associated state agencies, academics, and health stakeholders, and is fielded with the assistance of RTI International.
If you have been contacted to complete this important survey and have questions or concerns, please contact RTI at 1-833-947-2577.
