Time Spent with HIV Viral Load > 1500 Copies/mL Among Persons Engaged in Continuity HIV Care in an Urban Clinic in the United States, 2010–2015

Research output: Contribution to journalArticle

Abstract

Persons with HIV who have entered care but have viral load > 1500 copies/mL may be the source of the majority of new HIV infections in the United States. We followed patients engaged in continuity care in the Johns Hopkins HIV Clinical Cohort between January 2010 and August 2015. We estimated person-time spent with viral load > 1500 copies/mL while in care after antiretroviral therapy (ART) initiation, while in care, and while alive. Person-time was classified according to the most recent viral load measurement. Of 11,283.1 person-years in care on after ART initiation, 11,954.7 person-years in care and 13,990.0 total person-years of follow-up spent alive, 12.5, 14.8%, and between 12.6 and 27.2%, respectively (depending on assumptions about the viral load of persons lost to clinic) were spent with viral load > 1500 copies/mL. Patients with lower baseline CD4 cell count, younger age, black race, history of injection drug use, or baseline hazardous alcohol use spent more time with viral load > 1500 copies/mL after ART initiation.
