Linkage to care after HIV diagnosis among men who have sex with men and transgender women in Lima, Peru.

In Lima, Peru, HIV prevalence is estimated to be 15% among men who have sex with men (MSM) and 30% among transgender women (TW). We investigated timely linkage of MSM and TW to HIV care, as linkage to antiretroviral therapy (ART) is critical to protect the health of those living with HIV and to prevent onward transmission. We investigated linkage within 90 days of HIV diagnosis by matching data from two studies conducted in Lima between 2013 and 2015 to national ART program records. We used generalized linear modeling to assess predictors of timely linkage and late presentation to care. Of 487 newly-diagnosed MSM and TW, only 44% presented for care at an HIV clinic within 90 days. Timely linkage was less common among TW (aPR 0.7, 95% CI 0.5-1.0), those younger than 24 (aPR 0.8, 95% CI 0.6-1.0), and those reporting a history of sex work (aPR 0.7, 95% CI 0.6-0.9). Proximity to an ART program clinic was not associated with linkage; most participants linked to clinics offering "LGBTQ-friendly" care. The pattern of clinics selected by participants suggests the importance of concerns about confidentiality and stigma in decision-making about where to link to care.
