The Effect of Racial Concordance for Black Patients in Addiction Treatment: A Scoping Review of the Literature.

BACKGROUND

In the United States, Black people with substance use disorders (SUDs) have less access to treatment and worse treatment outcomes compared to White people. Though systemic racism is the root of these inequities, adapting treatment settings to serve this population may be a pragmatic way to improve access and outcomes. Shared racial identity between a patient and a provider, or , is one feature of culturally tailored care that may improve treatment access, experiences, and outcomes for Black people. There is some evidence that racial concordance improves medical treatment for Black patients in non-addiction settings, but it is unknown whether racial concordance affects experiences or outcomes in addiction treatment.

METHODS

We conducted a scoping review guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-to understand the effect of racial concordance on Black patients in addiction treatment. Three reviewers read each title and abstract to identify eligible articles. The inclusion criteria were: (1) Black patients; (2) treatment access, experiences, or outcomes; and (3) patient-provider racial concordance in addiction treatment. One reviewer completed full-text reviews and data extraction.

RESULTS

We identified 259 nonduplicate articles and completed full-text reviews of 77 articles. Eleven articles, published between 1971 and 2016, met criteria. Racial concordance was not associated with treatment access or engagement, though it was associated with some positive outcomes including increased perceived provider empathy. Few studies met the review criteria and there were no randomized controlled trials.

CONCLUSIONS

The studies identified in this review did not provide adequate evidence that racial concordance improved treatment access, experiences, or outcomes for Black patients. Future research should include a wider range of outcome measures, including relational measures (eg, medical trust, discrimination) and examine whether and under what circumstances racial concordance improves experiences and outcomes for Black patients in addiction treatment.
