I. Background Recently, CDC issued recommendations calling for HIV screening for patients aged 13-64, when the individual accesses the health care system 1. For many patients, especially those without a primary care provider, the emergency department (ED) is the primary or only contact point for the health care system. Testing individuals while they are in the ED has the potential to identify persons who do not perceive themselves to be at risk for HIV. Several academic EDs have begun to offer HIV testing 10, and have initially indicated promising results.
