Harbor Homes, Inc. d/b/a Harbor Care will implement a state-wide evidence-based substance use disorder/ co-occurring mental health treatment and recovery support services program (Cynthia Day Family Center) for women ages 18+ who are pregnant, post-partum, and/or parenting (PPW) and require low-intensity or high-intensity residential substance use disorder treatment, and are homeless or at-risk-of homelessness. The children of the women will also be provided with care on-site with their mothers. Harbor Care offers integrated substance use/ co-occurring disorder (SUD/COD) treatment, primary and oral healthcare, and housing services to this population, including a disproportionate share of veterans, justice-involved adults, and adults with co-occurring disorders. The geographic catchment area is the state of New Hampshire, with a focus on Hillsborough County (Target Region). As one of only two entities in NH currently operating a clinically-intensive residential SUD/COD treatment program for pregnant and parenting women (CDFC), Harbor Care has the physical space, programming, partnerships and staff expertise to fully implement all activities required. Residential services will occur within Harbor Care’s licensed 66-bed facility in Nashua, Hillsborough County, NH. SAMHSA funds will be used to expand and enhance NH’s treatment and recovery capacity by building and testing a trauma-informed, integrated Family Centered Treatment model tailored to the unique needs of PPW and their families experiencing or at risk of homelessness in NH (project goal). Four primary objectives will occur over the 5-year grant period: (1) To expand residential and outpatient treatment services capacity for PPW by 35%, conducting outreach to 500 families (100 each year) and serving 250 homeless/at-risk women with SUD/ COD (50 each year), reducing addiction severity by an average of 60%; (2) To improve recovery outcomes for PPW and their families by 50% at 6 months by building and testing an integrated health care, behavioral health treatment and recovery support services care model that reflects best practices of a Level-5 Family Centered treatment model and SAMHSA Level VI Integrated Care ; (3) To develop and implement medical, behavioral, and social service care for an estimated 150 children (50 each year residing on-site with their mothers) and family members of PPW; (4) To train and/or educate 200 of NH’s service providers (40 each year) to increase their capacity to recognize SUD/COD in PPW and actively participate in care using best practices. Anticipated outcomes include: (1) Decreasing: recidivism into homelessness; illicit drug/alcohol use and relapse; mental illness symptoms; readmission to inpatient SUD facilities/psychiatric hospitals; avoidable ED visits; negative encounters with law enforcement; number of children in foster care; first-year medical costs of drug-exposed infants; and (2) Increasing/improving: parenting and family functioning; family reunification outcomes; engagement in employment; personal income; social support/social connectedness; engagement with integrated health care; and child-related health, education and social outcomes. Harbor Care will implement in-person and telehealth-based universal screening in 25+ service access points throughout NH to ensure those with the greatest need are recruited for the program. At the end of the project, the NH will have an integrated system of care in place for PPW, responsive to its most vulnerable community members, with Harbor Care achieving a Level V Family-Centered Treatment model functioning within a Level VI Integrated Care system. Grant-funded staff will utilize evidence-based practices through a trauma-informed, harm-reduction model to meet the needs of the population of focus.
