The NFusion IV System of Care will improve mental health outcomes for children, youth and young adults (birth to age 21) at risk for or with serious emotional disturbance (SED) and their families by expanding access to trauma and grief informed, culturally responsive evidence-based mental health services and related recovery support services, improved policy, practice and infrastructure, cross-agency collaboration and sustainable financing for five rural medically underserved counties in North Mississippi, Alcorn, DeSoto, Prentiss, Tippah, and Tishomingo. The NFusion IV System of Care expansion will ensure that children, youth, and young adults at risk for or with SED, and their families, receive effective services within their communities, and that providers collaborate to coordinate care in a family-friendly and culturally responsive manner. EBPs will include Screening, Brief Intervention and Referral to Treatment; Trauma-Focused Cognitive Behavioral Therapy; Cognitive Behavioral Therapy; Moral Recognition Therapy; Dialectical Behavior Therapy; Mental Health First Aid; youth-guided and family leadership. Project Name: NFusion IV System of Care. Populations served: 45% Female; 51% Male; 2% Transgender; 3% LGBTQI+; 38% African American; 5% Multiracial; 1% American Indian; 1% Asian; 5% Hispanic/Latinx; 50% trauma-involved; 45% COD; 85% at or below poverty level; 1% age birth < 5; 13% age 5-9 year; 13% age 10-12; 38% age 13-15 years; and 35% age 16-21 years. Strategies: The SOC expands trauma and grief informed care, cultural and linguistically responsive evidence-based mental health services, suicide prevention and intervention, policy development with a co-serving network of agencies strengthening transitional planning, integrated mental health treatment with cross-agency care coordination coupled with wraparound recovery support services with linkages to vocational counseling, education services, primary healthcare, dental, substance abuse prevention, stable housing, including independent living. Each participant will work with a care team that facilitates the identification and implementation of an individualized service plan in partnership with the child/youth, family, supports to achieve their personal goals. The SOC expansion will include family/youth peer support, family and youth leadership development, mentoring, and youth-guided activities. Goals: 1) Expand, integrate and sustain the SOC improving access, infrastructure and sustainable financing while ensuring a flexible, innovative CQI approach, cross-agency collaboration, implementing trauma/grief informed care; 2) Meaningfully involve children, youth and young adult consumers and family/caregivers in their own care and the broader governance of the SOC; 3) Facilitate a network of co-serving providers wrapped around the system of care who use trauma and grief-informed care, evidence-based practices and programs to assess, screen, treat, and manage mental health, including suicide risk; 4) Improve mental health functioning, embedding evidence-based and evidence-informed services and supports in early childhood, youth and young adult intervention services and mental health disorders treatment; 5) Improve health equity with targeted outreach in underserved communities to engage racial, ethnic and LGBTQI+ minorities into SOC services.
