, antibiotic-impregnated catheters, antisep- tic dressings and hubs) have had some positive effect on CLABSI rates, but the most important way to reduce the risk of CLABSI is remove the catheter.
It is a good practice on ICU rounds to evaluate the need for each tube, catheter, or device every day so that the devices may be removed as soon as possible.
Obviously infected lines, indicated by draining purulence or erythema, should be removed immediately, whereas catheters suspected of being infected may be wire changed and the tip sent for culture.
