Effectiveness of an HIV care model integrated into addiction care based on medication-assisted treatment for HIV-positive people who use drugs.

Our objective was to evaluate the effectiveness of initiated or reinitiated antiretroviral therapy (ART) in HIV-positive active drug users receiving integrated HIV and addiction care in a harm reduction setting. We performed a study of HIV-positive persons who use drugs (PWUD) in a harm reduction unit in Madrid, Spain. Participants received HIV care integrated into addiction care and received at least one dose of observed ART based on medication-assisted treatment between January 2013 and December 2019. Individuals newly diagnosed with HIV (n = 13) had a greater median CD4 cell count at baseline were less likely to be late presenters, had a greater CD4 cell count increase, and were less likely to have AIDS in comparison to those who were aware of their HIV status (n = 87) at initiation or reinitiation of ART. The overall VS was 73% in the intention-to-treat (ITT) analysis and 92.4% in the modified intention-to-treat (mITT) analysis. People who were engaged in OST, people with >90% adherence to ART, and older people were positively associated with VS in the multivariate analysis. An HIV care model integrated into a harm reduction facility demonstrated a high uptake of HIV treatment, retention in care, improvement in adherence, and achievement of VS. [ABSTRACT FROM AUTHOR]
