Methods: We conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) -guided search in PubMed and PsycInfo for research on the effect of race concordance on addiction treatment outcomes for Black patients. Three reviewers read each title and abstract; one reviewer completed full-text reviews and data extraction. Discrepancies were discussed until consensus was reached. Articles meeting inclusion criteria addressed: 1) Black individuals; 2) treatment outcomes; and 3) patient-clinician race concordance in SUD treatment. We included peer-reviewed articles and scholarly commentaries.
In a subsequent analysis, we identified the elements of treatment pertaining to the three spheres of recognition (i.e., affection and care, acknowledgment of achievement, and legal rights) in the articles reviewed and explored the potential for race concordance to improve patient experience in each domain.
Results: The scoping review identified 329 non-duplicate articles. We completed full text reviews of 141 articles; 14 articles met criteria. Articles were published between 1971-2021 (13 before 2002). We identified one randomized clinical trial examining the effects of race concordance for Black patients (n= 6). At the one-year follow-up, the three retained Black patients in race-concordant dyads reported less intravenous drug use and decreased usage of shared needles. Of the remaining 13 non-randomized studies, three reported significant associations with race concordance, with polysubstance abstinence, perceived provider empathy, and less time in jail nine-months post-treatment. The remaining studies did not report associations between race concordance and treatment outcomes.
Some findings in this review suggest the potential for race concordance to engender recognition via affective care by increased empathy in patient-clinician relationships and achievement through shared understanding of treatment goals. Legal recognition was not represented in the review findings, though ability to make informed decisions about medical care given institutional policies could be a proxy for legal recognition in medical settings.
Conclusions: The inconclusiveness regarding the effect of race concordance on SUD treatment outcomes may be due to the lack of measures related to recognition in the studies reviewed. Given the value that patients and clinicians place on race concordance, future research should explore how recognition by Black clinicians, through emotional investment, mutual reassurance, and equity in decision making, affects SUD treatment outcomes.
