Cost Effectiveness of Novel RNA Testing Intervention: Total Cost (Including Both Testing and HIV-positive Patient Management) Per Participant (Base Case Patient Modeled) Secondary · Data collected over 2 years, data is a predicted time point extrapolated to 10 years

Model outputs will include an analysis of the cost effectiveness of the novel testing intervention assessing several parameters of the HIV prevention and care cascade using stochastic, agent-based mathematical modelling. The population of interest modeled was 18- to 39-year-old heterosexuals in Kenya. The age range coincides with the sampled population in this study (NCT03508908) which provided the majority of the parameters for the networks and behavioral modules in the simulation. The observations from this study were weighted to match the sex and age composition reported in the Kenya Fact a

Cost Effectiveness of Novel RNA Testing Intervention: Disability-Adjusted Life Years (Base Case Patient Modeled) Secondary · Data collected over 2 years, data is a predicted time point extrapolated to 10years

Disability-adjusted Life Year (DALY) is an index calculated as the sum of years of life lost (YLL) plus the years lost due to disability (YLD), where 1 DALY represents one lost year of healthy life. The higher the DALY index value, the worse the outcome, where there is no theoretical minimum ore maximum index value. the sampled population in this study (NCT03508908) which provided the majority of the parameters for the networks and behavioral modules in the simulation.

Sponsor's own description

This study will assess the impact of an HIV-1 RNA testing intervention targeting adult patients aged 18-39 years who seek urgent care for symptoms at primary care facilities and meet specific risk criteria for acute HIV infection. All newly diagnosed HIV-infected patients in the intervention arm will be linked to care and offered both immediate treatment and assisted partner notification. Partners will also be tested using the HIV testing intervention, and pre-exposure prophylaxis will be offered to uninfected individuals with HIV-infected partners. The cost-effectiveness of this intervention will be evaluated.
