How do CLABSI infections most often occur?

• A. Direct spread from urinary tract
• B. Migration of skin bacteria along the catheter insertion site or hub contamination
• C. Hematogenous seeding from a distant infection
• D. Contaminated IV fluids

Answer: (D)

Central line infections almost always start with bacteria that colonize the catheter surface, typically from the patient’s own skin. Bacteria migrate along the external insertion tract or contaminate the catheter hub when it’s accessed, and once inside the catheter, they form a biofilm that sticks to the lumen and serves as a reservoir for bloodstream infection. This intraluminal/extraluminal colonization is far more common than infections caused by contaminated IV fluids or by distant infections seeding the line. Because of this, preventing CLABSI centers on strict aseptic technique during insertion and handling of the line, thorough hand hygiene, proper hub and lumen disinfection, and minimizing the line’s duration.
