The U.S. Centers for Disease Control and Prevention (CDC) today published new recommendations for health care providers that are designed to make voluntary HIV screening a routine part of medical care for all patients aged 13 to 64. The recommendations aim to simplify the HIV testing process in health care settings and increase early HIV diagnosis among the estimated more than 250,000 HIV-positive Americans who are unaware of their infection. The recommendations also include new measures to improve diagnosis among pregnant women and further reduce mother-to-child HIV transmission. The Revised Recommendations for HIV Testing of Adults, Adolescents, and Pregnant Women in Health Care Settings were published today in CDC's Morbidity and Mortality Weekly Report (MMWR).
Increasing the proportion of people who know their HIV status is an essential component of comprehensive HIV treatment and prevention efforts in the United States. Early diagnosis is critical in order for people with HIV to receive life-extending therapy. However, today, nearly 40 percent of individuals diagnosed with HIV are diagnosed within one year of infection progressing to AIDS, when it may be too late for them to fully benefit from treatment. Additionally, studies show that most people who learn they are infected take steps to protect their partners, while people who are unaware of their infection are estimated to account for between 50 percent and 70 percent of new sexually transmitted HIV infections.
"We urgently need new approaches to reach the quarter-million Americans with HIV who do not realize they are infected," said Dr. Julie L. Gerberding, CDC director. "People with HIV have a right to know that they are infected so they can seek treatment and take steps to protect themselves and their partners."
The new recommendations are designed to overcome several barriers that hindered implementation of the earlier recommendations, which called for HIV testing for patients in health care settings with high HIV prevalence (above 1 percent) and for all high-risk individuals. Implementation of these recommendations was difficult because many health care facilities do not have information on HIV prevalence, and many providers report that they do not have sufficient time to conduct risk assessments. Physicians also report that the processes related to separate, written consent and pre-test counseling for HIV testing have posed significant barriers. In surveys and in consultations held by CDC, health care providers consistently reported these time-consuming processes were not feasible in emergency rooms and other busy health care settings.
"Our goal is to ensure that everyone who receives medical care also has the opportunity to learn if they are infected with HIV," said Dr. Kevin Fenton, Director of CDC's National Center for HIV, STD and TB Prevention. "These new recommendations will make routine HIV screening feasible in busy medical settings where it previously was impractical. Making the HIV test a normal part of care for all Americans is also an important step toward removing the stigma still associated with testing."
CDC continues to support the full range of HIV prevention interventions needed to reduce HIV infections in the United States, including comprehensive interventions for both HIV-infected and high-risk individuals. As part of these efforts, CDC believes it is essential to reach everyone with the opportunity to learn whether they are infected with HIV. These recommendations are designed to maximize opportunities for early diagnosis in health care settings, but must be supplemented with innovative approaches to expand testing in community settings and ensure linkages to prevention and care.
