The Ukrainian Institute on Public Health Policy (UIPHP), in collaboration with leading experts from Yale University and the University of Pennsylvania, proposes to create an addiction and HIV prevention technology transfer center focused on HIV prevention and addiction treatment in Ukraine. The proposed Ukrainian HIV International Addiction Technology Transfer Center (UHI-ATTC) will expand and enhance clinical and organization competencies, capacity and evidence-based knowledge, skills and attitudes of the HIV prevention and addiction workforce in Ukraine through effective training, coaching, mentoring, technical assistance, technology transfer, dissemination, and sustainability strategies. The UHI-ATTC will support expansion and enhancement of innovative evidence-based treatment practices with a focus on MAT with methadone, buprenorphine, and XRNTX. We will deploy evidence-based strategies consistent with SAMHSA's mission and strengthen it with innovative training, dissemination, ongoing technical assistance, implementation support, and fidelity maintenance strategies to implement culturally relevant evidence-based, health-focused, and person-oriented practices to 400 medical professionals over three years using in-person and technology-based training strategies. UHI-ATTC goals are to: create the first ATTC in Ukraine to expand and enhance addiction treatment services for people with or at risk for HIV through our established stakeholders and collaborative partnerships; develop a three-year strategic plan that focuses on addiction treatment for primary and secondary HIV prevention; utilize innovative technology transfer, technical assistance and training strategies to promote the adoption of evidence-based addiction treatment practices, participate in activities across the ATTC network to support and promote the adoption of evidence-based practices, recovery oriented systems of care and educational standards.
