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.
