2015 OMAS Survey


The 2015 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 2015 OMAS builds upon prior Ohio Medicaid-sponsored surveys to identify trend changes in the Ohio’s Medicaid, Medicaid-eligible, and non-Medicaid populations. The 2015 survey is representative of all Ohioans – survey staff conducted over 42,000 adult interviews and 10,000 child interviews by adult proxy.

The 2015 OMAS is a MEDTAPP funded project sponsored by the Ohio Department of Medicaid, Ohio Department of Health, and The Ohio State University. The survey vendor is RTI International, a non-profit organization that provides research and technical services.

Survey Data

The 2015 OMAS public use dataset and associated documentation are 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, zip code, and census tract. Researchers interested in obtaining a dataset with these identifiers should contact GRC to learn more about the process for acquiring the restricted access research dataset.

Many of the 2015 survey questions have also been administered in previous years. Download the variable crosswalks to learn which survey measures are comparable across years.

2015 Public Use File

Changes to the 2015 OMAS data include revisions to the derived dichotomous variables “flp138_flag” and “fpl138_m_flag” – please note that the continuous variable for FPL (fpl_pct) is not impacted. Additionally, a correction has been made to the variable “wt_c”, child weight variable, for children 0-1 years of age.”

Design and Methods

The 2015 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. Additionally, to address cultural/ethnic/racial variations, African-Americans were oversampled and Hispanics and Asians were set into separate sample lists via surname techniques.
