Multicenter Study Clinical Trial Controlled Clinical Trial
Hydrogel/silver ion-coated urinary catheter reduces nosocomial urinary tract infection rates in intensive care unit patients: a multicenter study.
Indwelling urinary catheters are the leading source of nosocomial urinary tract infections (NUTIs). The Bardex I.C. catheter is a hydrogel latex Foley catheter with a monolayer of silver metal applied to the inner and outer surfaces of the catheter. We investigated the Bardex I.C. catheter for its ability to decrease the NUTI rate in critical care units. ⋯ A trend toward a reduction in NUTIs with the use of the hydrogel/silver-coated catheter was noted in all intensive care units at each institution as shown by the unadjusted and adjusted catheter-associated infection rates. One hospital demonstrated a statistically significant reduction in NUTIs. However, statistical significance was not met when the results were adjusted. The cost analysis at one institution demonstrated cost savings with the use of the silver-coated catheter. Future analysis may require a double-blind, prospective-controlled study of longer duration to reach statistical significance.
