Pattern of linkage and retention in HIV care continuum among patients attending referral HIV care clinic in private sector in India

Continued engagement throughout the HIV care continuum, from HIV diagnosis through retention on antiretroviral therapy (ART), is crucial for enhancing impact of HIV care programs. We assessed linkage and retention in HIV care among people living with HIV (PLHIV) enrolled at a private HIV care clinic in Pune, India. Of 1220 patients, 28% delayed linkage after HIV diagnosis with a median delay of 24 months (IQR = 8-43). Younger people, women, low socioeconomic status, and those diagnosed at facilities other than the study clinic were more likely to delay linkage. Those with advanced HIV disease at diagnosis and testing for HIV due to HIV-related illness were linked to care immediately. Of a total of 629 patients eligible for ART at first CD4 count, 68% initiated ART within 3 months. Among those not eligible for ART, only 46% of patients sought subsequent CD4 count in time. Multivariate logistic regression analysis revealed that patients with initial CD4 count of 350-500 cells/cu mm (OR: 2, 95% CI: 1.1-3.5) and500 cells/cu mm (OR: 2.1, 95% CI: 1.2-3.7) were less likely to do subsequent CD4 test on time as compared to those with CD450 cells/cu mm. Among patients not eligible for ART, those having12 years of education (OR: 0.4, 95% CI: 0.2-0.9) were more likely to have timely uptake of subsequent CD4 count. Among ART eligible patients, being an unskilled laborer (OR: 2.2, 95% CI: 1.1-4.2) predicted lower uptake. The study highlights a long delay from HIV diagnosis to linkage and further attrition during pre-ART and ART phases. It identifies need for newer approaches aimed at timely linkage and continued retention for patients with low education, unskilled laborers, and importantly, asymptomatic patients.
