Aimed at shifting and improving the delivery of addiction treatment within county jails, Health Management Associates (HMA) will partner with the Washington/Baltimore High Intensity Drug Trafficking Area (W/B HIDTA) and Fairfax County Sheriff’s Office to deliver a novel Project ECHO clinic. Funded by W/B HIDTA to support county jails in their region, the Medication for Opioid Use Disorder (MOUD) in County Jails ECHO Clinic will provide participants with HMA training specifically focused on initiating or expanding the use of MOUD within their facilities. The project will broaden county knowledge and understanding of MOUD and its place in the criminal justice system, increase the use of MOUD with evidence-based and emerging promising practices, and promote a culture that supports MOUD in jails.
