HIV status and substance use disorder treatment need and utilization among adults in the United States, 2015-2019: Implications for healthcare service provision and integration

Introduction: Substance use disorders (SUD) are associated with HIV acquisition and care disruptions. Most research focuses on clinical samples; however, we used a nationally representative, community-based sample to estimate SUD treatment need and utilization by HIV status. Methods: We included participants from the 2015-2019 National Survey on Drug Use and Health aged 18 and older who met past-year DSM-IV SUD criteria (n = 22,166). Participants self-reported whether a healthcare professional ever told them they had HIV or AIDS [i.e., people with HIV (PWH), non-PWH, HIV status unknown]. Outcomes included past-year: 1) any SUD treatment use; 2) any specialty SUD treatment use; and 3) perceived SUD treatment need. Survey weighted multivariable logistic regression models estimated the likelihood of each outcome by HIV status, adjusting for age, sex, race/ethnicity, education, survey year, health insurance status, and household income. Results: Overall, 0.5 % were PWH and 0.8 % had an HIV unknown status. Any past-year SUD treatment utilization was low across all groups (10.3 % non-PWH, 24.2 % PWH, and 17.3 % HIV status unknown respondents). Specialty SUD treatment utilization was reported by 7.2 % of non-PWH, 17.8 % PWH, and 10.9 % HIV status unknown respondents. Perceived treatment need was reported by 4.9 % of non-PWH, 12.4 % of PWH, and 3.7 % of HIV status unknown respondents. In adjusted models, PWH were more likely than non-PWH to report any past-year SUD treatment utilization (aOR = 2.06; 95 % CI = 1.08-3.94) or past-year specialty SUD treatment utilization (aOR = 2.07; 95 % CI = 1.07-4.01). Among those with a drug use disorder other than cannabis, respondents with HIV-unknown status were less likely than HIV-negative individuals to report past-year perceived treatment need (aOR = 0.39; 95 % CI = 0.20-0.77). Conclusions: Despite high SUD treatment need among PWH, more than three quarters of PWH with SUD reported no past-year treatment. Compared to non-PWH, PWH had higher treatment utilization and higher specialty treatment utilization, but SUD treatment was low across all groups. As SUD is associated with adverse HIV outcomes, our findings highlight the need for the integration of SUD treatment with HIV testing and care. Increasing access to SUD treatment could help reduce negative SUD-related outcomes along the HIV care continuum.
