Approximately 80,000 central venous catheter–related bloodstream infections occur in United States intensive care units each year [1,2]. In general, the diagnostic approach to catheter-related bloodstream infection (CRBSI) consists of clinical evaluation and microbiologic confirmation with separate blood cultures obtained from the catheter as well as a peripheral vein.
The clinical features and diagnosis of CRBSI will be reviewed here. Issues related to treatment of CRBSI are discussed in detail separately. (See "Treatment of intravascular catheter-related infections".)
For surveillance purposes, the Centers for Disease Control and Prevention (CDC) has introduced the term laboratory-confirmed bloodstream infection (LCBI) . LCBI must meet at least one of the following criteria:
●Patient has a recognized pathogen cultured from one or more blood cultures, and the pathogen is not related to an infection at another site.
●Patient has at least one of the following signs or symptoms: fever (>38.0°C), chills, or hypotension, and the pathogen is not related to an infection at another site or, if the organism is a common commensal, it must be present from two or more blood cultures drawn on separate occasions.To continue reading this article, you must log in with your personal, hospital, or group practice subscription.
