A Scoping Review of the Utilization of Opioid Use Treatment, Harm Reduction, and Culturally Tailored Interventions Among Racial/Ethnic Minorities in the United States.

As part of a multilayered scoping review, we assessed literature on prevention and management interventions for racial/ethnic minorities in the United States (US) who non-medically use prescription opioids and/or who use illicit opioids such as heroin. The review specifically focused on access to and uptake of medications for opioid use disorder (MOUD) and harm reduction resources. We conducted a scoping review of peer-reviewed literature and governmental reports published between January 2000 and August 2024 on patterns of access to, and acceptability and utilization of, overdose prevention and opioid use management resources among racial/ethnic minorities in the US. Searches were conducted on Cochrane, PubMed, Embase, and Google Scholar, with us examining studies on the uptake of MOUD, such as buprenorphine and methadone, syringe services programs (SSPs), safe consumption sites, and harm reduction resources like naloxone (used to reverse overdoses) and fentanyl test strips (used to test for the presence of fentanyl in drug supplies). Additionally, we sought to identify and describe existing interventions for opioid use prevention and management that have expressly incorporated cultural adaptations related to racial/ethnic minorities' specific needs and preferences in an effort to improve participants' sense of salience and acceptability and thus enhance utilization. We further endeavored to leverage this scoping review towards the development of research and intervention guidelines contoured to improve future scholarship and programming with these populations. The existing evidence suggests that racial/ethnic minorities in the US, specifically Black individuals, have diminished access to and/or utilization of preventive and management resources and amenities such as buprenorphine and naloxone, owing to structural deficits, provider bias, socioeconomic obstacles, geographic barriers, and communal stigma and distrust. Black individuals, relative to White individuals, also appear less likely to report using SSPs to obtain syringes and related resources, but across racial groups, those who used SSPs were more likely to be trained in, possess, and/or use naloxone. Further, there have been very few culturally tailored interventions for harm reduction or MOUD; there were limited data across the reviewed works on Native American/Indigenous or Asian populations; and the broader body of literature lacks methodological rigor. We close by proposing a cultural humility-focused model for better meeting the complex needs of these populations through research and primary and secondary intervention.
