SJCH's Compton YFTREE - St. John's Community Health (SJCH) will implement the Compton Youth and Family Treatment and Recovery Project (Compton YFTREE) to expand access to comprehensive, family-centered, trauma-informed, evidence-based substance use disorder and co-occurring disorder treatment and recovery support for children ages 11 and under, adolescents ages 12-17, young adults ages 18-25, their families and primary caregivers, and pregnant and parenting women in Compton and surrounding South Los Angeles communities. The project will use SJCH's integrated network of primary care clinics, school-based health centers, and community-based services, with Dominguez High School Health Center and other established sites serving as key entry points and the Community Wellness Center serving as the central hub for outpatient treatment, family services, peer recovery support, groups, and aftercare as capacity expands. SJCH will serve 50 unduplicated children, adolescents, and young adults with SUD and/or COD in Year 1 and 100 annually in Years 2-5, for a total of 450 participants over the five-year project period. The population will be approximately 5% children ages 11 and under, 25% adolescents ages 12-17, and 70% young adults ages 18-25; approximately 55% will be male and 45% female. Participants are expected to have substantial clinical and social needs, including chronic or complex health conditions, housing instability, justice-system or foster care involvement, disability, and involvement with multiple service systems. Compton YFTREE will provide screening and developmentally appropriate early identification; comprehensive assessment and personalized treatment planning; integrated outpatient SUD/COD treatment using Screening, Brief Intervention, and Referral to Treatment, Motivational Interviewing, A-CRA, CBT, and Ask-Counsel-Treat; family services; case management and wraparound support; peer recovery support; access to medications for alcohol and opioid use disorders; tobacco and vaping intervention; overdose prevention education and naloxone distribution; healthy-choice education; aftercare; and connections to SJCH and community resources. Community Health Workers and a Youth Peer Recovery Specialist will be integrated into participating primary care teams and patient-visit workflows, working with providers and Licensed Clinical Social Worker staff to support engagement, treatment, recovery, and follow-up. The project will provide screening or developmentally appropriate early-identification services to at least 500 individuals in Year 1 and 1,000 annually in Years 2-5. At least 90% of enrolled participants will complete assessment and a personalized treatment plan within 14 days; 75% will begin recommended treatment within 14 days; 60% will remain engaged at three months or complete treatment earlier as planned; and 50% of participants completing the three-month reassessment will report abstinence or another age-appropriate favorable substance-use outcome. When appropriate, 75% of participants will have caregiver involvement, and 80% of surveyed caregivers will report increased ability to support recovery. All pregnant and parenting women engaged through the project will receive SUD/COD screening and needs identification, and 85% of those with identified needs will complete an intervention, begin treatment, or connect to an appropriate service within 30 days. The project will provide peer recovery support, care coordination, wraparound services, treatment navigation, and/or aftercare to at least 350 participants and ensure that all participants completing treatment receive an individualized aftercare plan. Compton YFTREE will improve timely access to treatment, strengthen recovery and family stability, and build a coordinated youth and family SUD/COD service model across SJCH's Compton network.
