Nosocomial urinary infection and implicated microorganisms

Abstract

Introduction: The nosocomial urinary tract infections are a common complication and a major health problem due to complications and frequent recurrences. It aims to identify microorganisms involved in nosocomial urinary infections, their relationship with the use of probe and hospital stay. Materials & methods: A descriptive retrospective study. Surveillance bases restricting urinary tract infections hospital origins were reviewed; general characteristics were described and differences between the lengths of time of stay were screened by microorganism Kluskal Wallis for a significance level of 95%. Results: 167 urinary tract infections were found of hospital origin, the median age was found to be of 75; most females (58%), 34.1% associated with the use of probe; 10% died in the hospital, most came from the adult intensive care unit. The most frequently isolated microorganism was Escherichia coli (46.1%); patients contributed a median stay of 20 days. Significant differences in length of stay by microorganism isolated in catheter-associated urinary tract infection was found, the microorganism related to the greatest length of stay was Proteus mirabilis; the remaining differences were not significant. Conclusions: The most frequently isolated microorganism was Escherichia coli, Proteus mirabilis was found to be related to probe the use and length of stay, additional studies are required to determine associations between hospital stay and resistance phenotypes empirical treatment protocols available to the date, consistent microorganisms isolated.
