Cost-effectiveness of implementing HIV and HIV/syphilis dual testing among key populations in Viet Nam: a modelling analysis

摘要: Objectives Key populations, including sex workers, men who have sex with men, and people who inject drugs, have a high risk of HIV and sexually transmitted infections. We assessed the health and economic impacts of different HIV and syphilis testing strategies among three key populations in Viet Nam using a dual HIV/syphilis rapid diagnostic test (RDT). Setting We used the spectrum AIDS impact model to simulate the HIV epidemic in Viet Nam and evaluated five testing scenarios among key populations. We used a 15-year time horizon and a provider perspective for costs. Participants We simulate the entire population of Viet Nam in the model. Interventions We modelled five testing scenarios among key populations:(1) annual testing with an HIV RDT,(2) annual testing with a dual RDT,(3) biannual testing using dual RDT and HIV RDT,(4) biannual testing using HIV RDT and (5) biannual testing using dual RDT …
