In 2012, the Ohio Department of Medicaid redoubled its efforts to collect population-level health and health systems data specific to Ohio’s Medicaid and Medicaid eligible populations. These data were critical to assess the potential impacts of the Patient Protection and Affordable Care Act. With this intensified focus, the Ohio Department of Medicaid replaced the Ohio Family Health Survey (OFHS) with the Ohio Medicaid Assessment Survey (OMAS).
The 2012 Ohio Medicaid Assessment Survey (OMAS) is a critical resource for assessing health statuses, health care access and service utilization, and select behavioral risks for Ohioans, with an emphasis on current Medicaid members and adults who are potentially eligible to receive Medicaid insurance. The 2012 OMAS is the 5th iteration of the series and builds upon prior surveys to identify trend changes for Ohio's Medicaid, Medicaid-eligible, and non-Medicaid populations. It is a cross-sectional random probability survey of non-institutionalized Ohio adults aged 19 years and older and proxy interviews of children aged 18 years and younger.

Design and Methods
The 2012 OMAS is a complex designed dual-framed (cell phone and landline phone) cross-sectional telephone survey with a sample size of 22,929. The 2012 OMAS enabled analysis for Ohio’s Appalachian, rural, suburban, and metropolitan county clusters, and enabled selected analysis at Medicaid Managed Care Regions and the county levels. Survey weighting was performed in stages at the county, regional, state, oversample, and cell phone levels to provide robust analyses with inferential certainty. The 2012 OMAS excluded institutional settings such as university dorms, incarceration facilities, assisted living facilities, hospitals, and businesses. Additionally, to address cultural/ethnic/racial variations, African-Americans are oversampled and Hispanics and Asians are set into separate sample lists via surname techniques. The data collection period for the 2012 OMAS began in late May 2012 and finished in early October 2012. Download the full methods report to learn more about the design and data collection processes.

Research and Reports
Below is a list of briefs and reports that address key findings from the 2012 OMAS. In addition to these documents, descriptive tables are also available for download. These descriptive tables have information on the distribution of key variables for all of Ohio, the four county clusters, the eight Medicaid Managed Care Planning Regions, and those currently enrolled and not enrolled in Medicaid. Data on the adult variables are available for three populations: non-senior adults (ages 19-64), seniors (ages 65 and older, and all adults (ages 19 and older). Data on the child variables are provided for the population of all children (ages 0-18).
For any research using data from the 2012 OMAS, a research plan should be specified that includes primary hypotheses and corresponding statistical analysis strategies.
A one-page summary of the methods used to create the descriptive tables is also available for download.
