CLARE|MATRIX (C|M) is proposing the Overdose Treatment Access for Pregnant and Postpartum People (ODTx-PPP) project to focus on serving California's South and Central Los Angeles area. The geographical catchment area is part of Los Angeles (LA) County Service Planning Area 6 (SPA 6) and is comprised of 8 urban communities. The goal of the project is to expand access of naloxone to pregnant and postpartum people (PPP) residing in the south and central LA area, by 1) expanding SPA 6's prenatal and birthing care practitioners and providers, pharmacists, and social service providers, awareness and knowledge of overdose prevention, reversal, and Naloxone prescribing, 2) providing them with support and resources that will facilitate them to develop training and feedback peer networks, and 3) improving their attitude towards prescribing Naloxone to PPP by reducing stigma and provider bias against PPP using substances, and destigmatizing Naloxone prescription to nurture a landscape of more equitable access to OUD harm reduction and treatment for PPP. Through this project, C|M will use its expertise in opioid use disorder treatment, overdose prevention and response, and its outreach and training infrastructure to establish a Training of Trainers (ToT) model. C|M has secured the commitment of one partner, thus far, UCLA ISAP, to provide consultation for curriculum and training development and to participate in the Community Engaged Advisory Board. C|M will train 200 prenatal and birthing care practitioners and providers, pharmacists, and social service providers over the five-year period of this grant. To successfully implement this project, C|M will use 1.30 FTE from existing staff, who will seamlessly integrate project priorities into daily operations. The staffing plan includes a Project Director and Lead Trainer as key personnel and an Evaluator as support with data and tracking.
