Brief summary

The primary purpose of this study is to assess the burden of advanced HIV disease (CD4 cell count \<200 or \<350 cells/μL) among new patients and those returning to care after a gap in treatment, and the extent to which low coverage of CD4 cell count measurement among these patients may prevent adequate management of those with advanced HIV disease.

Detailed description

This study is part of a multi-regional IeDEA study across four African regions to assess the burden of advanced HIV disease among PLWH at ART initiation and re-initiation. Among adults and adolescents. The WHO defines advanced HIV disease as having a CD4 cell count \<200 cells/uL or having WHO stage 3 or 4 disease. In the region, the aim is to enrol 500 participants aged 18 years and older and to conduct a cross-sectional evaluation that will include assessments of WHO clinical stage, CD4 cell count, and ART exposure status at enrolment/re-enrolment into care, as well as barriers to HIV testing and care. In addition, extraction of routinely collected clinical data on all study participants from within the cohort dataset, including prospective data on participant treatment outcomes, and CD4 and HIV VL measurements performed as part of routine patient care. These data will be harmonized using the IeDEA-DES, which is a common data model for sharing observational HIV data designed and maintained by the Data Harmonization Working Group (DHWG) of IeDEA.
