2017 OMAS Survey

The 2017 OMAS is a critical tool for assessing health care access, health status, and health care use for Ohio’s current and potential future Medicaid participants. The 2017 OMAS builds upon prior Ohio Medicaid-sponsored surveys to identify trend changes in the Ohio’s Medicaid, Medicaid-eligible, and non-Medicaid populations. The 2017 survey is representative of all Ohioans – survey staff conducted almost 40,000 adult interviews and over 9,000 child interviews by adult proxy.

The 2017 OMAS is a MEDTAPP funded project sponsored by the Ohio Department of Medicaid and The Ohio State University. The survey vendor is RTI International, a non-profit organization that provides research and technical services.

Survey Data

The 2017 OMAS public use dataset and associated documentation will be available for download. This public use dataset contains all of the data collected from the adult and child questionnaires, except select geographic identifiers, including county of residence and zip code. Researchers interested in obtaining a dataset with these identifiers should make a data-use inquiry to learn more about the process for acquiring the restricted access research dataset.

2017 Public Use File

Please note that the 2017 Public Use Files were updated in April 2023 to address updates to the way that derived race-ethnicity variables were coded and how health insurance variables were imputed to better align with updates that were made as part of the 2021 OMAS data. Survey weights were also updated as part of the revision. If you utilized the earlier version of the file, your estimates may be slightly different, and we encourage you to re-download the file for analysis.

Design and Methods

The 2017 OMAS was structured as a stratified random digit dial dual-frame (cell phone and landline phone) complex designed (multiple strata) telephone survey that enables analyses at the state, Medicaid Managed Care Plan region, and select 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. It excluded institutional settings such as university dorms, incarceration facilities, assisted living facilities, hospitals, and businesses. The selection method ensured a reliable sample of residents.
