Residential substance use disorder treatment is designed to treat more severe substance use disorders. Considering the strong association between substance use and HIV, providing HIV prevention services during residential substance use disorder treatment is imperative. However, not all treatment facilities offer the same services, and differences in residential substance use disorder treatment facilities providing HIV prevention services might stem from facility-level characteristics. Using 3 years (2018-2020) of cross-sectional data from the National Survey of Substance Abuse Treatment Services, we examined which treatment facility characteristics were associated with having HIV prevention services. Using a logistic regression model with HIV prevention services as the outcome, we found that facilities that were accredited, engaged in community outreach, and offered assistance with housing and transportation were more likely to provide HIV prevention services. Furthermore, facilities in the Midwest and West were less likely to provide HIV prevention services than those in the South.
