Abstract

OBJECTIVES:

To quantify the HIV care cascade in a Cape Town sub-district to understand rates of linkage to and engagement in HIV care.

METHODS:

We used routinely collected data to reconstruct the treatment cascade for 8382 infected individuals who tested HIV + in 2012/2013. We obtained data on patient gender, year of initial HIV-positive test, age at testing and initial CD4 cell count and defined five stages of the HIV care cascade. We quantified attrition across cascade stages.

RESULTS:

Two-thirds of the sample (5646) were women. Men were older at time of first testing (36.5 vs. 31.3 years) and had more advanced HIV disease at diagnosis (298 vs. 404 CD4 cells/µL for women). The median duration of follow-up was 818 days. Among women, 90.5% attended an initial HIV care visit, 54.6% became eligible for antiretroviral therapy under local guidelines during follow-up, 49.3% initiated ART and 45.6% achieved a therapeutic response. Among men, 88.0% attended an initial HIV care visit, 67.4% became ART eligible during follow-up, 48.0% initiated ART and 42.4% achieved a therapeutic response. Approximately 3% of women and 5% of men died during follow-up.

CONCLUSIONS:

We were able to reconstruct the HIV treatment cascade using routinely collected data. In this setting, rates of engagement in care differ by gender in key stages of the cascade, with men faring worse than women at each cascade point. This highlights the need for interventions aimed at encouraging earlier testing, linkage, ART initiation and retention among men.
