Younger People with HIV Are Missing Out in the Continuum of Care


Young people with HIV are less likely to access and benefit from HIV care and treatment at all levels of the "care cascade" from testing to starting antiretroviral therapy (ART) to achieving viral suppression, according to findings reported in the June 17, 2013, advance edition of JAMA Internal Medicine. Overall, only about 25% of HIV positive people achieved undetectable viral load.

It is well known that effective ART can dramatically reduce the risk of AIDS-related illness and death, but recent research has shown that only about one-quarter of HIV positive people in the U.S. have been tested, linked to care, started treatment, maintained good adherence, and achieved undetectable viral load. The rest fall between the cracks at various stages of the so-called cascade of care.

H. Irene Hall from the U.S. Centers for Disease Control and Prevention (CDC) and colleagues evaluated disparities in these indicators between different groups of people with HIV categorized by sex, age, race/ethnicity, and transmission category (e.g., men who have sex with men, heterosexual men and women, injection drug users).

Effective treatment not only benefits individuals with HIV, but also prevents transmission of the virus, so disparities in care and treatment may contribute to the higher incidence rates seen in some groups, the study authors noted as background.

Usingdata from the CDC's National HIV Surveillance System, the researchers estimated the number of people with HIV who are aware and unaware of their status. They then calculated the percentage who were linked to care within 3 months of HIV diagnosis, based on CD4 T-cell count and viral load. Finally, they estimated percentages of people who remained in care, were prescribed ART, and achieved viral suppression using data from the Medical Monitoring Project, a surveillance system of people receiving HIV care in selected representative areas.


o   82% had been diagnosed as HIV positive;

o   66% were linked to care;

o   37% were retained in care;

o   33% were prescribed ART;

o   25% had viral load suppressed to >200 copies/mL.

"Significant age disparities exist at each step of the continuum of care," the researchers summarized. "Additional efforts are needed to ensure that all persons with HIV receive a diagnosis and optimal care to reduce morbidity, mortality, disparities in care and treatment, and ultimately HIV transmission."

"Individuals, health care providers, health departments, and government agencies must all work together to increase the numbers of people living with HIV who are aware of their status, linked to and retained in care, receiving treatment and adherent to treatment," they concluded.

"The sobering numbers of those missing out on effective treatment because they did not know they were infected and those who knew their status but did not seek care spurred collaboration between the HIV treatment and prevention movements, 2 areas with different funding streams that often operated independently of one another," wrote Katerina Christopoulos and Diane Havlir from the University of California at San Francisco in an accompanying commentary. "Already the HIV community has mobilized to further develop and study interventions that address bottlenecks in the cascade. Achieving an AIDS-free generation will be within reach if, and only if, these efforts succeed."
