The New Jersey Department of Human Services' Division of Mental Health and Addiction Services (DMHAS) in partnership with the Rutgers University Behavioral Health Care (RUBHC) Center for Integrated Care (CIC), will implement the collaborative care model (CoCM) in two primary care and one pediatric care clinics located in Newark (Essex County) and Elizabeth (Union County), two federally designated medically underserved areas (MUA) in New Jersey. The CoCM initiative will serve 1,100 unduplicated individuals (100 people in year 1, 300 in years 2-4 and 100 in year 5) with serious mental illness (SMI), serious emotional disturbance (SED) and co-occurring physical health and/or substance use disorders (SUDs) who present in the primary care and pediatric clinics. Teams of psychiatric consultants, behavioral health care managers, nurse care managers, and support staff coordinate behavioral health services with primary care utilizing the CoCM, including patient-centered, team-based, measurement-based, and population-based health care, as well as evidence-based behavioral health practices, such as brief cognitive behavioral therapy, early detection clinical high-risk for psychosis, and medications for opioid use disorder. Project goals include increasing the identification and treatment of individuals with mental health and SUDs, increasing patients’ attendance and retention in care, monitoring metabolic parameters of individuals receiving antipsychotics, using measurement-based care (e.g., PHQ-9) to improve treatment of depression, and screening children for depression and anxiety using an evidence-based tool. DMHAS will review data collected by the RUBHC CIC to determine whether the project is meeting objectives, and it will ensure sustainability of the initiative.
