What is a central line-associated bloodstream infection (CLABSI)?

A central line-associated bloodstream infection (CLABSI) specifically refers to an infection that occurs when bacteria or other pathogens enter the bloodstream through a central venous catheter. Central lines are used for patients who require long-term intravenous access for medications, fluids, or blood products. The risk of infection increases due to the direct connection to the bloodstream and the potential for bacteria to enter the system at the insertion site or along the catheter itself.

This type of infection is significantly associated with the presence and maintenance of central lines, and its classification emphasizes the importance of monitoring and managing these devices to prevent infections. Effective practices to reduce the risk of CLABSI include proper hand hygiene, maintaining a sterile environment when inserting or caring for the catheter, and routinely assessing the need for the line.

Other options listed do not reflect the specific definition of CLABSI. Surgical infections relate to operative procedures rather than the use of central lines. Infections linked to intravenous antibiotics might occur but are not specific to central lines. Infections related to urinary catheters describe a different category of healthcare-associated infections, known as catheter-associated urinary tract infections (CAUTIs), which are distinct from bloodstream infections associated with central lines.
