HIV self-testing economic evaluations
While great strides have been made in expanding antiretroviral therapy (ART) coverage and achieving viral suppression, knowledge of HIV status is lagging behind. There are multiple potential solutions to improving knowledge of HIV status, including improving HIV testing algorithms and through the use of HIV self-testing (HIVST). Governments throughout sub-Saharan Africa are currently improving their HIV testing strategies and trying to identify use-cases for HIVST.
HIVST in particular is recognized as an innovative method to increase the proportion of people who know their HIV status, and has been demonstrated to have high accuracy and acceptability. Nationwide distribution of HIVST, however, will largely depend on cost and cost-effectiveness compared to the current standard of care. The cost of HIVST delivery has been found to be higher than routine facility-based HIV testing using rapid, finger stick test with whole blood, mainly driven by HIVST kit cost and additional costs associated with community-based distribution. These high costs may be different depending on the approach to HIVST delivery. We work on these topics in several African countries.
