Patient navigation for perinatal substance use disorder treatment: A systematic review.

BACKGROUND: Substance use during the perinatal period (i.e., pregnancy through the first year postpartum) can pose significant maternal and infant health risks. However, access to lifesaving medications and standard care remains low for perinatal persons who use substances. This lack of substance use disorder treatment access stems from fragmented services, stigma, and social determinants of health-related barriers that could be addressed using patient navigators. This systematic review describes patient navigation models of care for perinatal people who use substances and associated outcomes. METHODS: We conducted a structured search of peer-reviewed, US-focused, English- or Spanish-language articles from 2000 to 2023 focused on 1) patient navigation, 2) prenatal and postpartum care, and 3) substance use treatment programs using PubMed, Scopus, PsycINFO, and CINAHL databases. RESULTS: After meeting eligibility criteria, 17 studies were included in this review. The majority (n=8) described outpatient patient navigation programs, with notable hospital (n=4) and residential (n=3) programs. Patient navigation was associated with reduced maternal substance use, increased receipt of services, and improved maternal and neonatal health. Findings were mixed for engagement in substance use disorder treatment and child custody outcomes. Programs that co-located care, engaged patients across the perinatal period, and worked to build trust and communication with family members and service providers were particularly successful. CONCLUSION: Patient navigation may be a promising strategy for improving maternal and infant health outcomes among perinatal persons who use substances. More experimental research is needed to test the effect of patient navigation programs for perinatal persons who use substances compared to other models of care.

Accessing perinatal substance use disorder care in your local community: A case study of an innovative hub and spoke network in western North Carolina.

INTRODUCTION: The incidence of substance use disorders (SUD) in the general population and in the pregnant person population has risen over the last 20 years. Concurrently, both perinatal and SUD care in rural areas is laden with access barriers including but not limited to geographical distance from potential treatment and stigma. An integrated outpatient perinatal substance use disorder (PSUD) clinic in an urban area in western North Carolina (WNC) found that patients who traveled further for prenatal care were less likely to continue seeking care in the postpartum period. Acknowledging that the risk of overdose increases in the postpartum period, the PSUD clinic utilized a hub and spoke model to promote healthcare accessibility. METHODS: The clinic adapted the Vermont hub and spoke model and the CHARM (Children and Recovering Mothers) collaborative. The urban hub in WNC has now developed eight spokes in rural communities. The hub provides education and technical assistance to the rural spokes, and the two engage in bidirectional referral pathways. This manuscript details the model and analyzes the existing strengths and barriers at two spokes, a family medicine Federally Qualified Health Center and a hospital affiliated obstetrics and gynecology practice and analyzes their process of implementation of integrated outpatient perinatal substance use care. RESULTS: Both spokes found coaching relationships and the sharing of resources such as clinical guidelines useful to begin prescribing buprenorphine for PSUD. Their context led one spoke to begin prescribing within one year while the other took two years. CONCLUSION: Comparing and contrasting these spokes serves to demonstrate that across many contexts, a hub and spoke model is a replicable intervention for rural perinatal substance use access to care barriers. Comparing the two spokes emphasizes the need for adaptation as well as standardization of the model to improve evidence-based PSUD care most effectively.
