Cook County Jail Using Medications Plus Substance Treatment and Recovery Training (JUMP START) - Project JUMP START (Jail Using Medications Plus Substance Treatment And Recovery Training) aims to enhance and expand substance use services for persons with opioid use disorder (OUD) who are detained in the Cook County Jail (CCJ), both pre- and post-release from jail. Through our medical arm (Cermak Health Services) at CCJ, the project will screen and diagnose persons with OUD and provide: medications for OUD (MOUD)--including opioid overdose reversal medications (OORM), pre-release psychosocial services, pre-release SMART Recovery groups, integrated care for co-occurring psychiatric/mental health disorders, post-release community engagement with MOUD and community SUD treatment, and assistance with transportation, vocational/job training, and sober recovery housing. Cook County contains 5,275,541 residents, including the City of Chicago and 133 suburban municipalities, and is the second most populous county in the United States. The Cook County Jail (CCJ) serves approximately 100,000 persons per year. It is estimated that 12% of individuals in jails in the US have an OUD.(1) Presently, in CCJ, there are 747 detainees with an OUD diagnosis with 172 (23%) receiving any form of OUD. Even fewer detainees are receiving MOUD plus psychosocial supports or counseling. Project JUMP START will be open to all adult detainees (men and women) who are over the age of 18, diagnosed with an OUD, and determined to have 4 months or less time before release into the community. With this Project, we aim to serve 20 unduplicated persons each month, 240 unduplicated persons each year, and 1140 total unduplicated persons with OUD over the course of the grant (with three-month start-up period). Through our evidence-based interventions, we will increase the number of persons receiving OUD treatment, decrease opioid use in this population, and decrease risk of overdose. By addressing other issues (housing, employment, transportation, co-occurring disorders, post-release coordination), Project JUMP START will increase community engagement and long-term recovery for this target population. The project goals include: 1) Expand access to MOUD and psychosocial supports for detainees at CCJ with OUD. 2) Screen and treat co-morbid mental health issues in persons with OUD at Cook County Jail and post-release. 3) Provide recovery support services to the most vulnerable patients to access community-based treatment, remain in care, and promote long-term recovery. 4) Work with internal and external partners to provide wrap-around psychosocial and recovery support services.
