Experiences of pregnant and postpartum people of color engaged in a randomized clinical trial of medication to treat opioid use disorder during pregnancy: A "Positive Outliers" analysis.

introductionRacial and ethnic inequities persist in medication treatment initiation and adherence for pregnant and postpartum people with opioid use disorder (OUD). Our objective was to understand the experiences of "positive outliers," specifically pregnant and postpartum people of color with OUD who utilized medication treatment and engaged in a randomized clinical trial for buprenorphine despite historical, cultural, and structural barriers.

methodsWe conducted two sets of semi-structured qualitative interviews. First, trained peers with lived expertise as mothers in recovery interviewed individuals who identified with a non-white race and/or ethnicity and enrolled in the Medication Treatment for OUD in Expectant Mothers (MOMs) trial (NCT03918850). Second, we interviewed principal investigators, clinicians, and research coordinators from the 13 MOMs trial sites. We used an inductive thematic approach informed by the Social Ecological Model of Racism and Anti-Racism. Transcripts were double-coded and reviewed until consensus was reached. Preliminary findings from participant and staff interviews were merged and triangulated with peers to inform theme development.

resultsWe completed 17 interviews with MOMs trial participants from 7 sites. Participants identified as Hispanic (29%), Black non-Hispanic (24%), multi-racial Hispanic (18%), multi-racial non-Hispanic (18%), and American Indian, Native Hawaiian, or Pacific Islander (12%). Thirty-two interviews with trial staff were also completed. Three themes emerged: (1) Although some participants expected racist treatment and research exploitation, all participants interviewed reported non-discriminatory, non-judgmental care within the MOMs trial; (2) Compassionate care, frequent, personalized, and integrated encounters, and emotional support helped counteract prior stigmatizing and discriminatory health care interactions, enabling participants of color to feel particularly supported, trusted, and empowered during the MOMs trial; and (3) Despite pervasive cultural stigma around addiction and concerns about taking an investigational drug while pregnant, participants expressed that pregnancy status, care team trust, and transparent communication with MOMs trial staff encouraged medication utilization and adherence.

conclusionFacilitators of successful engagement in the MOMs trial and retention in medication treatment among pregnant and postpartum people of color with OUD included non-judgmental care, sustained trust, and frequent contact. Key perinatal OUD clinical interventions and trial improvements include personalized communication and scheduling flexibility to promote engagement of marginalized populations.
