Health and Healthcare Outcomes Research Program

Health and Healthcare Outcomes Research Program

Evaluating and improving healthcare quality, access, and economic outcomes for people with chronic health conditions.

Our focus

The Health and Healthcare Outcomes Research Program carries out research related to evaluation and innovation in health care to improve health outcomes (i.e., access, quality of life, satisfaction, health related social needs, costs) for people with specific chronic conditions. Health policy implications of these outcomes are a key focus.

Current projects examine the uptake and outcomes of care coordination services and impacts of the pandemic on health care use and health related social needs.

What we do

Our research centers on evaluating and improving healthcare quality, access, and economic outcomes for people with chronic health conditions. With Dr. Hynes’ joint appointment at the US Department of Veterans Affairs (VA), Veterans are a special population focus of our research conducted at the VA. Our OSU-based research focuses on people with specific chronic diseases.

Our research employs health services research methods design (observational and interventional) and integrating large-scale health records, insurance claims (VA, Medicare) and survey data, including use of REDCap for data collection and management. Our OSU-based projects rely on research computing resources supported by the OSU Center for Quantitative Life Sciences, Health Data & Informatics program.
