What is the OEPS?

The Opioid Environment Policy Scan (OEPS) is an open-source data warehouse focused on the multi-dimensional risk environment impacting opioid use and health outcomes across the United States.

The OEPS provides access to data at multiple spatial scales, from U.S. states down to Census tracts. It is designed to support research seeking to study environments impacting and impacted by opioid use and opioid use disorder (OUD), inform public policy, and reduce harm in communities nationwide.

The OEPS Explorer makes it quick and easy to explore, visualize, and download data. Read more about the project, our methodology, and our data standards.

The OEPS is led by the Healthy Regions and Policies Lab, based at the Department of Geography & GIScience at the University of Illinois at Urbana-Champaign. It was developed for the Justice Community Opioid Innovation Network (JCOIN), an NIH HEAL Initiative, as part of the Methodology and Advanced Analytics Resource Center at the University of Chicago.
