Abstract

PURPOSE
This study took a retrospective approach to investigate patients with catheter-associated urinary tract infection (CAUTI) over 2 years at a single hospital's intensive care unit (ICU) to identify meaningful risk factors and causative organisms.
MATERIALS AND METHODS
A retrograde analysis was performed on patients with indwelling catheters between January 2009 and December 2010 in Yeouido St. Mary Hospital medical and surgical ICU. CAUTI was defined as isolated bacterial growth of 100,000 colony-forming units or more either 48 hours after transfer to the ICU if a urinary catheter was placed before the transfer or 48 hours after insertion if the catheter was inserted in the ICU. Only the patients whose culture results were negative before ICU admission were included.
RESULTS
There were a total of 1,315 patients with indwelling urinary catheters in our hospital's medical and surgical ICU between January 2009 and December 2010. Of these patients, 241 had positive urine culture results, and 61 had CAUTI. Using multivariate logistic regression analysis, those with diabetes were 4.55 (p<0.001) times as likely to have occurrences of CAUTI than were those without and also had a 1.10-fold (p<0.01) longer duration of an indwelling catheter. Upon urine culture, among the 61 patients with CAUTI, Escherichia coli was the most common bacterium grown; it was identified in 24 patients (38.7%).
CONCLUSIONS
The factors and causative organisms contributing to the development of CAUTI in the management of ICU patients must be considered to prevent the occurrence of UTIs in this setting.
