Measuring Social and Spatial Inequities in Access to Opioid Use Disorder Treatment for Reducing HIV and HCV Transmissions (019)


Study Information

Access to treatment and medication for opioid use disorder (MOUD) is essential for reducing HIV and HCV transmissions. However, the spatial distribution of the resources for treatment and medication is a result of various social factors, which can include potential inequities.

To demonstrate the utility of a spatial perspective in evaluating access to MOUD resources, The University of Chicago and Argonne National Laboratory will use a simulation approach to evaluate how treatment and intervention locations affect HIV and HCV transmissions. This study will also evaluate interventions using scenarios of varying levels of spatial inequity in HepCEP, a validated agent-based model (ABM) for Hepatitis C Elimination in Persons Who Inject Drugs (PWID). Outcomes from this study may provide insight into the complex factors that drive MOUD treatment heterogeneity within communities using more spatialized approaches for evaluation of efficacy.
