The Centers for Disease Control published its long awaited guidelines for preventing transmission of human immunodeficiency virus and hepatitis B virus to patients on July 12, 1991. The guidelines recommend voluntary HIV and HBV testing of all health care workers performing exposure-prone invasive procedures. Special safeguards are applicable to any worker who is infected with HIV or the most virulent form of hepatitis B—i.e., hepatitis B e antigen positive (HBeAg). HIV or HBsAg-positive health care workers should not carry out exposure-prone invasive procedures unless an expert panel has approved and provided individualized guidance, and the patient is informed about the HCW's serological status.
Characteristics of exposureprone procedures include digital palpitation of a needle tip in a body cavity or the simultaneous presence of the worker's fingers and a sharp instrument in a poorly visualized or confined anatomic site.
