“…While hospitals performing CDC NHSN CAUTI surveillance have developed systems to capture catheter days in their intensive care units, few have the ability to capture the data in other areas of the hospital. Kim and colleagues 14 conducted a study of 99,834 patients over a 2-year period (2002-2004) comparing CAUTI rates using both device-days and patient-days as the denominator in their calculations and found that the 2 rates were highly correlated. They concluded that rates based on patient-days can serve as a surrogate for rates based on device-days.…”

PURPOSE:The purpose of this study was to determine the effect of a silver-alloy hydrogel catheter on symptomatic catheter-associated urinary tract infections (CAUTIs).DESIGN:Multicenter before-after non-randomized cohort study.SUBJECTS AND SETTING:Seven acute care hospitals ranging in size from 124 to 607 beds participated in this study. The study population included adult patients with a positive urine culture 2 or more days after admission, who underwent Foley catheterization.METHODS:Catheter-associated urinary tract infection surveillance was conducted at each hospital for at least 3 months during the use of a standard catheter and 3 months during the use of the silver-alloy hydrogel catheter. Both the National Healthcare Safety Network (NHSN) surveillance and a clinical definition of CAUTI were used for rate calculation.RESULTS:A 47% relative reduction in the CAUTI rate was observed with the silver-alloy hydrogel catheter compared to the standard catheter when both infection definitions were used (0.945/1000 patient days vs 0.498/1000 patient days) (odds ratio = 0.53; P < .0001; 95% CI: 0.45–0.62). When only NHSN-defined CAUTIs were considered, a 58% relative reduction occurred in the silver-alloy hydrogel period (0.60/1000 patient days vs 0.25/1000 patient days) (odds ratio = 0.42; P < .0001; 95% CI: 0.34–0.53). Antimicrobial days for CAUTIs decreased from 1165 (standard catheter period) to 406 (silver-alloy hydrogel period).CONCLUSIONS:Use of a silver-alloy hydrogel urinary catheter reduced symptomatic CAUTI occurrences as defined by both NHSN and clinical criteria.
