HIV Care Continuum and Meeting 90-90-90 Targets: Cascade of Care Analyses of a US Military Cohort

Introduction The new initiative by the Department of Health and Human Services (DHHS) aims to decrease new HIV infections in the U.S. by 75% within 5 years and 90% within 10 years. Our objective was to evaluate whether the U.S. military provides a good example of the benefits of such policies. Materials and methods We conducted an analysis of a cohort of 1,405 active duty military personnel with HIV enrolled in the Natural History Study who were diagnosed between 2003 and 2015 at six U.S. military medical centers. The study was approved by institutional reviewboards at the Uniformed Services University of the Health Sciences and each of the sites. We evaluated the impact of Department of Defense (DoD) HIV care policies, including screening, linkage to care, treatment eligibility, and combined antiretroviral therapy (cART) initiation on achieving viral suppression (VS) within 3 years of diagnosis. As a secondary outcome, we evaluated the DoD's achievement of UNAIDS 90-90-90 targets. Results Nearly all (99%) were linked to care within 60 days. Among patients diagnosed in 2003-2009, 77.5% (95% confidence intervals (CI) 73.9-80.6%) became eligible for cART within 3 years of diagnosis, 70.6% (95% CI 66.6-74.1%) overall initiated cART, and 64.2% (95% CI 60.1-68.0%) overall achieved VS. Among patients diagnosed in 2010-2015, 98.7% (95% CI 96.7-99.5%) became eligible for cART within 3 years of diagnosis, 98.5% (95% CI 96.4-99.4%) overall initiated cART, and 89.8% (95% CI 86.0-92.5%) overall achieved VS. Conclusions U.S. military HIV policies have been highly successful in achieving VS goals, exceeding the UNAIDS 90-90-90 targets. In spite of limitations, including generalizability, this example demonstrates the feasibility of the DHHS initiative to decrease new infections through testing, early treatment, and retention in care.
