"Forty-one percent of local jail jurisdictions initiated behavioral or psychological treatment for OUD, 24% continued MAT for persons admitted with a current prescription or getting services from a methadone clinic prior to admission, and 19% initiated MAT for inmates with OUD at midyear 2019. Regardless of region, jail jurisdiction size, locality, or opioid overdose death rate, larger percentages of jail jurisdictions initiated behavioral or psychological treatment for OUD than initiated or continued MAT. 

"In states with 24.0 or more opioid overdose deaths per 100,000 U.S. residents ages 15 to 74, 28% of jail jurisdictions continued MAT, while 25% initiated MAT. In states with fewer than 10.0 opioid overdose deaths per 100,000, 19% of jail jurisdictions continued MAT and 13% initiated MAT for OUD."
