BACKGROUND HIV self-testing (HIVST) is effective in improving the uptake of HIV testing among key populations. Complementary data on the economic evaluation of HIVST is critical for planning and scaling up HIVST. This study aimed to evaluate the cost of a community-based organisation (CBO)-led HIVST model implemented in China. METHODS An economic evaluation was conducted by comparing a CBO-led HIVST model with a CBO-led facility-based HIV rapid diagnostics testing (HIV-RDT) model. The full economic cost, including fixed and variable cost, from a health provider perspective using a micro costing approach was estimated. We determined the incremental cost-effectiveness ratios of these two HIV testing models over a 2-yeartime horizon (i.e. duration of the programs), and reported costs using US dollars (2021). RESULTS From January 2017 to December 2018, a total of 4633 men were tested in the HIVST model, and 1780 men were tested in the HIV-RDT model. The total number of new diagnoses was 155 for HIVST and 126 for the HIV-RDT model; the HIV test positivity was 3.3% (95% confidence interval (CI): 2.8-3.9) for the HIVST model and 7.1% (95% CI: 5.9-8.4) for the HIV-RDT model. The mean cost per person tested was USD10.38 for HIVST and USD41.45 for HIV-RDT. The mean cost per diagnosed person was USD310.12 for HIVST compared with USD585.58 for HIV-RDT. CONCLUSION Compared to facility-based HIV-RDT, a CBO-led HIVST program is cheaper and more effective among MSM living in China.
