The National Institute on Drug Abuse’s (NIDA) Justice Community Overdose Innovation Network (JCOIN 2.0) provides an opportunity to advance the criminal legal system (CLS) as a provider of services, particularly for those with opioid use disorders (OUD) or other substance use (SU) behaviors who are at risk for overdose. The Administrative (Admin) Core is co-led by Dr. Faye Taxman and Ms. Amy Murphy with Dr. Carrie Pettus and collaborators from each Coordination Translation Center (CTC) Core and proposed CTC affiliates. The proposed Admin Core for JCOIN 2.0 is the same team that led JCOIN 1.0, with the addition of Dr. Henderson who will assist the CTC in engaging minoritized communities, practitioners, and scholars. The CTC team represents a diverse and experienced cadre of scholars, practitioners, and people with lived experience (PWLE) in the CLS and team members with expertise in overdose and SU prevention and treatment. The Admin Core will serve the critical function of being the communication center that allows for the receipt and transmission of all resources regarding JCOIN initiatives. The Admin Core and its website and social media outlets serve as a comprehensive resource for researchers, policymakers, treatment providers, CLS professionals, PWLE and their loved ones, and the general public. The CTC Admin Core will provide support to NIDA, funded research Hubs (Hubs), Methodology and Advanced Analytics Resource Center (MAARC), Advisory Panel(s), the JCOIN Steering Committee (SC), and other CTC Cores. The Admin Core proposes to pursue three aims. Aim 1: Maintain and enhance external-facing communications infrastructure established in JCOIN 1.0 and expand that infrastructure in JCOIN 2.0. Admin Core diffusion of information will be measured by website engagement, social media reach, podcast downloads, and diversity of characteristics and backgrounds of individuals consuming disseminated content. Aim 2: Provide internal collaboration and communication infrastructure and logistical support. In JCOIN 2.0, the Admin Core will focus benchmarks for success around the use and enhancement of communication infrastructure, ease and frequency of infrastructure use, development of publications and toolkits, and successful support for the JCOIN SC. Aim 3: Monitor network outputs. This aim will be achieved through positive collaboration among the JCOIN community and external stakeholders, and timely and innovative reporting to NIDA and grantees. The Admin Core maintains a highly utilized JCOIN website that has been enhanced in each year of JCOIN 1.0. The Admin Core aims to add enhancements during JCOIN 2.0 including a) an Opportunity Board; b) JCOIN Events Calendar; c) Sensitivity readers and inclusive language bots; d) Diverse audience augmentations; e) Public and private dashboards; f) JCOIN Town Halls; and g) Educational and Artificial Intelligence features. JTEC will continue and expand in JCOIN 2.0, which is a dynamic online learning center that rea...
