Prevalence of nosocomial urinary tract infection in PICU of referral children hospital in Iran

ABSTRACT

To determine the prevalence of the occurrence, risk factors and microbiology for acquiring UTIs in the PICU of one of the main referral children hospital in Iran. A surveillance study was conducted among all children admitted to PICU in the Mofid children hospital in Tehran between July 2007 and July 2008. During the one year, 428 patients were admitted to PICU for 48 hours or more and a total of 31 [7.2%] acquired UTIs, yielding an overall incidence density, of 11 per 1000 PICU days. One bacteremic [4.3%] ICU-acquired UTIs occurred. Mean hospital staying in UTI patients was 22 days comparing with 7 days in other patients [P value<0.001] but mortality rate difference was not significant [P value=0.2]. The most common organisms isolated were Escherichia coli [30.4%], Kelebsiellapneumoniae[30.4%] and Candida a/b/cans[21.7%]. Monitoring of a PICU-acquired UTI is important in critically ill patients. The results of this study offer a reliable measure of the prevalence of nosocomial UTIs at hospitals in Iran and provide a baseline for future studies
