Technology-Enabled Learning Collaborative Program - Arizona State University (ASU), through the College of Health Solutions and the National Safety Net Advancement Center (SNAC), proposes the Arizona Maternal & Early Childhood Network for Training, Outreach, and Resilience (Arizona MENTOR), a statewide technology-enabled collaborative learning and capacity-building network designed to strengthen the maternal and early childhood behavioral health workforce and improve access to evidence-based care across Arizona. The project directly supports the goals of the HRSA Technology-enabled Collaborative Learning Program by expanding provider capacity, reducing professional isolation, strengthening organizational implementation of evidence-based practices, and improving access to high-quality behavioral health services for pregnant and postpartum individuals, infants, young children, and families living in rural, frontier, tribal, border, and medically underserved communities. Arizona continues to experience significant maternal and early childhood behavioral health challenges. Approximately 91,000 pregnancies and nearly 78,000 births occur annually, with nearly half of all births financed by Medicaid. Persistent workforce shortages, behavioral health provider scarcity, geographic maldistribution of specialty services, fragmented referral systems, and implementation barriers limit access to timely behavioral health care, particularly in Health Professional Shortage Areas and medically underserved communities. Primary care, pediatric, obstetric, and behavioral health providers frequently lack access to multidisciplinary consultation, ongoing mentorship, and implementation support needed to integrate evidence-based behavioral health services into routine clinical practice. Arizona MENTOR will establish a statewide network of approximately 40 healthcare organizations, including federally qualified health centers, rural health clinics, critical access hospitals, tribal health organizations, county health departments, community behavioral health centers, safety-net health systems, and independent primary care, pediatric, family medicine, and obstetric practices. The project will engage multidisciplinary care teams consisting of physicians, nurse practitioners, physician assistants, behavioral health clinicians, psychologists, social workers, pharmacists, nurses, community health workers, peer support specialists, care coordinators, quality improvement professionals, and practice administrators. The project will implement an integrated technology-enabled collaborative learning model built upon ASU's established Project ECHO infrastructure and statewide practice transformation expertise. Three complementary strategies will be employed: (1) longitudinal virtual, case-based collaborative learning connecting community providers with interdisciplinary specialists; (2) individualized practice transformation support, including workflow redesign, quality improvement coaching, technical assistance, and implementation facilitation; and (3) a statewide community of practice supported by an online Learning Hub that provides implementation resources, evidence-based toolkits, recorded educational sessions, and peer learning opportunities. Clinical activities will focus on maternal mental health and perinatal substance use disorders, infant and early childhood behavioral health, behavioral health integration within primary care and obstetric settings, and coordinated family-centered, trauma-informed care. Over the three-year project period, Arizona MENTOR will recruit at least 40 partner organizations, train a minimum of 500 multidisciplinary healthcare professionals annually, increase participant knowledge and confidence in evidence-based maternal and early childhood behavioral health care, strengthen implementation of standardized screening, referral, and behavioral health integration practices, and improve care coordination across participating organizations.
