Introduction The urinary tract infection is the most common healthcare-associated infection. Sixty-six % to 86% of nosocomial UTI is known to be associated with urinary instrument such as urinary catheterization.

Methods Setting: a university hospital with 863 beds Methods: A prospective surveillance of UTI for the patients in MICU & SICU was performed and the infection rate was analyzed during the period from June 2005 to June 2007. From 2006, the urinary catheterization care was actively educated to the healthcare practitioners; especially the unnecessary bladder irrigation and catheter change were abandoned and other CDC guidelines for UTI prevention were recommended as well. UTI rate was compared between the pre- and post-intervention period. The urinary catheter utilization ratio was also analyzed.

Conclusions With the active education of urinary catheter care to the healthcare practitioners, the UTI rate decreased significantly, although the urinary catheter utilization ratio did not show a reduction.
