Hospital infections in a school hospital intensive care center in the north of Paraná state

Abstract

The objective of this descriptive study was to perform an epidemiologic characterization of hospital infections in an Intensive Care Centre of a teaching hospital in the north of Paraná State, from June 2003 to June 2004. A number of 1304 patient discharges were identified, 208 out of which presented hospital infection. Hospital infection rate was 15.95%. Staphylococcus aureus was the most frequently isolated microorganism with an incidence rate of 12.98%, followed by Pseudomonas aeruginosa 12.5%, Acinetobacter baumannii 9.61%; other microorganisms presented lower percentages. With respect to nosocomial infections topography, pneumonia had the highest incidence rate: 66.34%; urinary tract infections presented a 22.11% incidence rate, surgical site, 5.76% and the vascular system, 1.92%. Amongst the respiratory infections, S. aureus presented a 15.94% incidence rate, A baumannii, 13.76%, and P. aeruginosa, 9.42%. Regarding urinary tract infections, Candida sp. showed a 32.60% incidence rate, P. aeruginosa, 32.60%, E. coli, 10.86% and Enterobacter sp., 10.86%. Antimicrobial susceptibility test results showed that A. baumannii presented a sensitivity rate of 69,07 % to carbapenens. All S. aureus samples were sensitive to vancomycin and 34.5% were sensitive to oxacillin. Mortality incidence rate with respect to hospital infections was 27.88%.
