Diagnostic accuracy of the WHO clinical staging system for defining eligibility for ART in sub-Saharan Africa
This is a systematic review and meta-analysis on antiretroviral therapy
Abstract
The World Health Organization recommends that HIV-positive adults with CD4 count ≤500 cells/mm3 initiate antiretroviral therapy (ART). In many countries of sub-Saharan Africa, CD4 count is not widely available or consistently used and instead the WHO clinical staging system is used to determine ART eligibility. However, concerns have been raised regarding its discriminatory ability to identify patients eligible to start ART. The authors therefore reviewed the accuracy of WHO stage 3 or 4 assessment in identifying ART eligibility according to CD4 count thresholds for ART initiation
