Prince William County Community Services (PWC) of Virginia will implement a Children's Mental Health Initiative (CMHI) to screen 2,000 youth (250-550/year), serving all youth with individualized treatment plans, with special emphasis on 400 youth (65-125/year) with complex mental health conditions. PWC is an over 60% majority minority county with Hispanic (25.4%), Black (22.1%), Asian (10.2%) or Other (2.4%) residents. Staff will use culturally informed practices to implement the CMHI consistent with youth enrolled for services. Target groups include (1) minority populations (2) co-occurring SED and substance use disorder (SUD), emphasis on youth with opioid/fentanyl use as this is the fastest growing subgroup in care from 2019 to present, and (3) suicidal ideation and behavior of youth which is also increasing rapidly in PWC. Resource generation, sustainability planning, and the use of collaborative and integrated systems interventions will target two overall aims: (1) Strengthen the System of Care by improving understanding and implementation of SOC principles; offer training linked to clearly identified needs; expand trauma informed approaches to community organizations and businesses; improve policies; and increase youth and family engagement from planning, service delivery and service selection to evaluation. (2) Improve the Service Delivery System to increase access to Evidence-Based Practices (EBP), reduce wait times, increase trust and satisfaction, and improved retention in treatment. Four goals with 3-6 measurable objectives will be addressed: Goal 1. Expand capacity and access for youth/families with complex mental health needs with emphasis on minority, co-occurring SUD/OUD disorders and depression/suicidality to EBPs through systematic screening, treatment planning, and provision of EBPs with fidelity. Goal 2. Improve youth, family, engaged service/resource stakeholders, and community capacity to detect, refer and support youth with SED through improving trainings (mental health, SUD, trauma/resilience, suicide) and the use of technology to improve engagement in treatment, reinforcement of improvement, data collection, and micro-communications. Goal 3. Integrate system improvement activities and objectives via Network Analysis at the community and organization levels. Increase engagement of stakeholders to improve access and quality of services, resources, equity, and voice for minority populations. Goal 4. Incorporate the Connected County Care (C3) app platform for youth, caregivers, treatment providers and key stakeholder agencies to increase feedback, resource support and data collection targeting daily living skills, symptoms, social support, coping skills, and agency of youth and caregivers. To accomplish all goals a Governance Board of local key stakeholders that represent the diversity of the County will support a compreshensive and ongoing Needs Assessment, integrating recovery support services, trauma-informed approaches, and promoting and sustaining family and youth involvement. The process will be data-driven and evidence-based and will incorporate three strategic documents that will guide implementation and evaluation of the SOC: (1) Implementation Plan, (2) Sustainability Plan and, (3) Evaluation Plan. EBPs will be incorporated with a comprehensive evaluation process and system of care development activities to solidify a sustainable SOC. A Continuous Quality Improvement (CQI) model merged with Clinical Process Improvement (CPI) will identify gaps and successes and will be used to introduce frequent, small reviews and changes. The CMHI team has completed an interaction comparison for specific EBPs that will be introduced or expanded with SAMHSA seed dollars. These include Intensive Care Coordination, Collaborative Assessment and Managment of Suicidality, Trauma-Focused Cognitive Behavioral Therapy, Eye Movement Desensitization and Reprocessing, and Seeking Safety.
