摘要

This study is aimed at investigating the prevalence and associated risk factors of bacterial nosocomial infections in the intensive care unit (ICU) of the Provincial Hospital of Kenitra city of Morocco. For this purpose, 165 pathological specimens of154 patients were collected and analyzed for a period of 11 months; from 1st March 2012 to 30th January 2013. The obtained results showed that 40 of 154 patients develop bacterial nosocomial infections with a prevalence of 25.9%. Analysis of the statistical results revealed that nosocomial pneumonia represents the most common infection of about 48%, followed by urinary tract infection (36.5%), skin infection (9.7 %), and chest drain (5.8%). We have isolated fifty multiresistant bacteria including 46% ofAcinetobacter baumannii, 20% of Pseudomo-nas aeruginosa, 14% of Enterobacter cloacae, 8% of Klebsiella pneumoniae, 6% of Escherichia coli, and 6% of Aeromonas hydrophila. The intubation was the main risk factor.
