ADMINISTRATIVE CORE: PROJECT SUMMARY/ABSTRACT The Administrative Core of the HD2A Research Adoption Support Center (RASC) will host an efficient centralized home for the HD2A Program. It will provide the necessary infrastructure, operational and logistical support, and foster welcoming, productive and positive relationships within and across the RASC Cores and throughout the HD2A. With strong administrative and scientific leadership, RASC’s Administrative Core will design, develop, maintain and update user-friendly accessible platforms for HD2A grantees and the public. Robust online tools and resources will provide the field with the best of dissemination and implementation (D&I) methods and measures to maximize adoption of evidence-based substance use and pain interventions. Moreover, as the heart of the RASC, the Administrative Core will strive to foster a culture of HD2A community. The Administrative Core is the organizing hub of all RASC logistics and resources. It provides a coordination and collaboration infrastructure for the entire HEAL D2A Program. It is engineered to: ASSESS, adapt and respond to the needs of the Innovation Projects, the RASC Substance Use Disorder Implementation Support (SUD-IS), Pain Implementation Support (Pain-IS), and Research & Evaluation (R&E) cores, as well as the broader HEAL D2A Program; ASSIST with project management, coordination, and collaboration; ADVANCE practical, meaningful, widespread and long-range impact, by leveraging innovative, high-quality and accessible D&I resource materials. As the “grease and glue” for the RASC, the Administrative Core is the structural foundation for day-to-day work, technical support, research synergy, and efficiency--always striving toward the goal of high-profile impact. We aim to ignite expansive impacts throughout the fields of substance use disorder and pain intervention research. Leadership of the Administration Core has extensive experience managing a national implementation support network (the SAMHSA Technology Transfer Centers [ATTC; MHTTC]), an established resource upon which the RASC elaborates, expands and advances with state-of-the science D&I methods, measures, and a deep roster of individuals with translational research and practice expertise. As with the other cores and the overall RASC, the Administrative Core will be dedicated to at the very least meeting the needs and advancing the D&I impact of the HD2A program, but our ultimate goal is to change the field in order make evidence-based interventions for pain and substance use disorders readily and equitably available.
