Experiences of Discrimination and Treatment Outcomes Among Pregnant and Postpartum People With Opioid Use Disorder [ID: 1376917]

INTRODUCTION: Experiences of discrimination among pregnant and postpartum people with opioid use disorder (OUD) are common and likely affect utilization of medication for OUD (MOUD), which is associated with reduced risk of overdose and death. We aimed to examine experiences of discrimination by prenatal care (PNC) and substance use disorder (SUD) treatment settings and estimate its effect on the risk of various MOUD utilization outcomes. METHODS: Patient-stakeholders co-designed survey questions to measure self-reported outcomes related to MOUD treatment utilization, return to substance use, and overdose. First, we examined the proportion of participants who endorsed items on a modified Healthcare Discrimination Scale and summed the total scores. Next, we quantified the effect of discrimination experienced by health care setting on postpartum MOUD utilization, return to use, and overdose using log-binomial models to calculate relative risk (RR) and 95% CIs. RESULTS: Among the 100 participants enrolled in the study, 57 reported experiencing discrimination, 56 within PNC and 33 within SUD treatment settings. Discrimination within PNC (RR 2.6, CI 1.06–6.40) and SUD treatment (RR 3.26, CI 1.59–6.70) were associated with increased risk of not using MOUD as prescribed. Discrimination within SUD treatment settings correlated with an increased risk of MOUD discontinuation (RR 2.56, CI 1.19–5.54) and return to use (RR 2.36, CI 1.18–4.73). CONCLUSION: Experiences of discrimination were common, especially within prenatal care settings, and discrimination was associated with poor MOUD treatment outcomes and risk of return to use. Interventions to address discrimination within health care settings can improve outcomes for pregnant and postpartum people with OUD.
