Medicaid Expansion Increased Medications For Opioid Use Disorder Among Adults Referred By Criminal Justice Agencies.

Abstract

Individuals involved with the US criminal justice system have high rates of opioid use disorder (OUD) but face significant barriers to evidence-based treatment. Using 2008-17 data from the Treatment Episode Data Set-Admissions, we examined trends in receipt of medications for OUD among individuals referred by criminal justice agencies and other sources both before and after Medicaid expansion. Individuals referred by criminal justice agencies were less likely to receive medications for OUD than were those referred by other sources during our study period, although this disparity narrowed slightly after Medicaid expansion. Receipt of medications for OUD increased more for individuals referred by criminal justice agencies in states that expanded Medicaid compared with those in states that did not. Medicaid expansion may improve evidence-based treatment for individuals with criminal justice involvement and OUD, although additional policy change outside the health care sector is likely needed to reduce persistent treatment disparities.
