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.
