Managing exposure to tuberculosis in the PACU: CDC guidelines and cost analysis

The Postanesthesia Care Unit (PACU) is an area of high risk for the transmission of Mycobacterium tuberculosis. The Centers for Disease Control (CDC) have recommended administrative controls, engineering controls, and personal protection devices to reduce the risks; nevertheless, perianesthesia nurses inhale airborne pathogens. The CDC guidelines are enforced by the Occupational Safety and Health Administration (OSHA). If an exposure occurs, the health-care facility has an OSHA-mandated course of action. The cost of follow-up of exposed persons can be high, depending on the patient census of the PACU at the time of unprotected exposure. This report presents the CDC guidelines for follow-up of exposure and costs based on typical surgical volumes and admission patterns for a large hospital with 10 thousand or more annual surgical procedures.
