(HealthDay News) — For young adults without known risk factors, a one-time routine HIV screen at 25 years would optimize clinical outcomes and be cost-effective, according to a study published in the January issue of the Journal of Adolescent Health.

Anne M. Neilan, MD, MPH, from Massachusetts General Hospital in Boston, and colleagues simulated HIV-uninfected 12-year-olds without identified risk factors who faced age-specific HIV infection risks. The authors modeled a one-time HIV screen ($36) at age 15, 18, 21, 25, or 30 years, each in addition to current US screening practices (30% screened by age 24).

The researchers found that all one-time screens detected a small proportion of lifetime infections (0.1% to 10.3%). A screen at 25 years led to the most favorable care continuum outcomes at age 25 compared to current screening practices, with a higher proportion diagnosed (77% vs 51%), linked to care (71% vs 51%), retained in care (68%  vs 44%), and virologically suppressed (49% vs 32%). A screen at age 25 years not only provided the greatest clinical benefit but also was cost-effective ($96,000/year-of-life saved [YLS]) by US standards of <$100,000/YLS compared with the next most effective screen.

"Focusing screening on adolescents and young adults ages 18 or younger is a less efficient use of a one-time screen among AYA than screening at a later age," the authors write.
