3. Promoting HIV Testing in Diverse Populations |

Revised Recommendations for HIV TestingIn September 2006, the US Centers for Disease Control and Prevention (CDC) published revised recommendations for These recommendations mean that healthcare providers should offer routine screening for HIV infection unless the prevalence of undiagnosed HIV infection in their patient population has been shown to be < 0.1%. In the absence of data on HIV prevalence in a particular area, individual providers and provider organizations should offer voluntary screening until data that demonstrate the presence of < 1 HIV-infected case per 1,000 patients screened, at which level routine HIV screening is no longer warranted. Other important recommendations in this initiative include:
Opt-out vs Opt-in Throughout most of the history of the HIV epidemic, opt-in testing, the usual process, has required written consent and pretest counseling, requirements that can pose barriers to performing wider testing. Routine opt-out HIV testing, on the other hand, involves performing HIV testing as part of a patient’s routine health evaluation, without pretest counseling—similar to screening for other medical conditions—while also preserving the patient’s right to decline testing. The CDC suggested that HIV screening should be included in the forms for general consent for medical care that patients typically sign in most clinical settings—in other words, that specific written consent for HIV screening should not be required. In another important change, these 2006 guidelines recommend that, in healthcare settings, prevention counseling need not be offered with HIV diagnostic testing or as part of HIV screening. Healthcare Settings The 2006 recommendations are intended for all healthcare providers in both the public and the private sectors in settings where other diagnostic and screening tests are routinely performed, including:
The recommendations, however, do not apply to nonmedical settings, such as mobile HIV testing vans. USPSTF Recommendations The US Preventive Services Task Force (USPSTF)—a program of the federal Agency for Healthcare Research and Quality—has also issued a strong recommendation that clinicians screen all adolescents and adults who may be at increased risk for HIV infection. In this context, increased risk means having ≥ 1 individual risk factor (listed below) for HIV infection or receiving healthcare services at a facility that is located in an area with a high prevalence of HIV infection or that serves a high-risk population. [USPSTF 2005] Individual risk factors include:
Patients who request an HIV test but who do not report individual risk factors may also be considered at increased risk for HIV infection, because these are likely to include individuals who may not be willing to disclose their high-risk behaviors. High-prevalence or high-risk clinical settings include:
In addition, the USPSTF strongly recommends routine HIV testing for all pregnant women. However, the group did not recommend routine screening for adolescents and adults who are not at increased risk for HIV infection.
