Bloodstream infection (BSI) is a major complication in patients with central venous catheters or other vascular-access devices. A positive culture from a catheter is one of the criteria used to diagnose this condition. However, pathogens are sometimes detected in catheters removed from patients with no evidence of a BSI. The risk for developing a BSI subsequent to removal of an infected catheter is unclear.
To explore this issue, researchers in France conducted a retrospective study involving patients in their intensive care unit (ICU) who had arterial, venous, or dialysis catheters inserted and left in place >24 hours and who survived >48 hours after catheter removal. In this ICU, catheters removed for any reason are routinely cultured usin…
