Human immunodeficiency virus (HIV) care continuum attrition is a major global public health challenge. Few studies have examined this problem in resource-limited settings. We aimed to assess cumulative, current, and historical achievement along China’s HIV continuum of care.
A nationwide, serial cross-sectional study of all individuals with HIV infection diagnosed in China between 1 January 1985 and 31 December 2015 was conducted using data from China’s HIV/AIDS information systems. Biennial estimates of the number of persons living with HIV were also used. We defined 7 steps in HIV care continuum as infected (estimated), diagnosed, linked, retained, enrolled, receiving antiretroviral therapy (ART), and virally suppressed. Cumulative, 30-year performance, and biennial performance during the most recent 10 years were examined.
A total of 573529 persons diagnosed with HIV infection were included. Cumulatively, 94% were linked, 88% were retained, 73% were enrolled, 67% were receiving ART, and 44% were suppressed. Greatest attrition was observed for adolescents, minorities, and those who reported injecting drug use as their route of infection. Improvement was observed from 2005 to 2015. As of the end of 2015, 68% among those infected were diagnosed, 67% among diagnosed were receiving ART, and 65% among those receiving ART were virally suppressed. After adjusting for those without viral load testing, the proportion suppressed increased to 89%.
Despite dramatic improvements, China faces serious challenges in achieving the Joint United Nations Programme on HIV/AIDS 90-90-90 targets, because of substantial attrition along its continuum of HIV care.
