Abstract
Housing insecurity is a critical social driver of health, strongly associated with increased risk of substance use, adverse medical and psychiatric outcomes, and legal and employment instability. These risks are particularly acute during pregnancy and parenting times of life, where housing instability exacerbates maternal stress and adversely affects infant and early childhood health. Patients who have completed residential substance use disorder treatment often have limited options regarding housing as they are often reintroduced to low-income environments and experience discrimination associated with their substance use problems. This pilot project evaluated the impact of a structured housing voucher intervention on housing stability and substance use–related outcomes among perinatal patients and mothers following discharge from residential substance use disorder treatment. Participants (n = 12) were enrolled in a voucher-based housing payment program for up to 12 months that provided rental assistance alongside integrated medical, psychiatric, substance use disorder treatment, and case management services. Monthly assessments were conducted to evaluate housing status, mental and physical health, legal and employment outcomes, and substance use outcomes. Our results indicated that participants showed reductions in housing insecurity and little substance use over the course of their participation in the study. Improvements were also observed in legal and employment domains, as well as in self-reported mental health indicators. These findings underscore the critical role of housing interventions in promoting sustained recovery and maternal–child well-being. Further investigation in larger, randomized samples is warranted to establish generalizability and inform policy implementation.
