Abstract

Background: The recently updated White House National HIV/AIDS Strategy (NHAS) includes specific progress indicators to improve the HIV care continuum in the USA, but the economic and epidemiological effect of achieving those indicators remains unclear. We aimed to project the impact of achieving NHAS goals on HIV incidence, prevalence, mortality, and costs among adults in the USA over 10 years. Methods: We constructed a dynamic transmission model of HIV progression and care engagement based on literature sources and the most recent published US Centers for Disease Control and Prevention data. We specifically considered achievement of the 2020 targets set forth in NHAS progress indicator 1 (90% awareness of serostatus), indicator 4 (85% linkage within 1 month), and indicator 5 (90% of diagnosed individuals in care). Findings: At current rates of engagement in the HIV care continuum, we project 524 000 (95% uncertainty range 442 000-712 000) new HIV infections and 375 000 deaths (364 000-578 000) between 2016 and 2025. Achievement of NHAS progress indicators 1 and 4 has modest epidemiological effect (new infections reduced by 2·0% and 3·9%, respectively). By contrast, increasing the proportion of diagnosed individuals in care (NHAS indicator 5) averts 52% (95% UR 47-56) of new infections. Achievement of all NHAS targets resulted in a 58% reduction (95% UR 52-61) in new infections and 128 000 lives saved (106 000-223 000) at an incremental health system cost of US 105 billion. Interpretation: Achievement of NHAS progress indicators for screening, linkage, and particularly improving retention in care, can substantially reduce the burden of HIV in the USA, but continued and increased financial investment will be required.
