Pathogens causing healthcareassociated urinary tract infection in intensive care unit patients

Abstract:

ObjectiveTo understand healthcareassociated urinary tract infection (HAUTI) and pathogens causing HAUTI in intensive care unit (ICU) patients, so as to provide scientific basis for the prevention and control of HAUTI. MethodsTargeted surveillance data about HAUTI  in 32 hospitals in 2013 were analyzed. ResultsA total of  23 680 ICU patients were monitored, 157 cases of HAUTI occurred,  HAUTI rate was 0.66%; the usage rate of urinary tract catheter was 80.83%，catheterassociated UTI was 1.25‰.  A total of 162 pathogenic strains were detected, the percentage of fungi, gramnegative bacteria, and grampositive bacteria was 40.74% (n=66)； 31.48 % (n=51), and 27.78% (n=45) respectively. ConclusionThe main pathogens causing HAIURI are fungi, comprehensive intervention measures should be taken to control HAUTI in ICU patients.
