Avaliação da resistência microbiana em hospitais privados de Fortaleza - Ceará

Abstract

The study assessed the presence of bacteria resistant to antimicrobial in the private hospitals network insured to a health plans operator from Fortaleza, Ceará. The study included patients using antimicrobials, and the samples of isolated antibiograms from adult patients from February 2009 to May 2010 were analyzed. Of the 1345 patients that were followed, it was observed that 1,321 cultures/antibiograms with microbial growth (at 55.94%), 739 of these cultures being the ICU unity with the highest rate of positive cultures. The most commonly isolated bacteria in the ward was Klebsiella pneumoniae, and in the ICU, Pseudomonas aeruginosa. Beta-Lactamase Enzymes of Expanded Spectrum (ESBL) were detected in 43.55% and 39.78% of Enterobacteriaceae isolated in the ICU and in the ward, respectively; 56.48% and 58.82% of Pseudomonas sp. in the ICU and in the ward, respectively; and 85.11% and 75.00% of isolated Acinetobacter sp. in the ICU and in the ward, respectively. Carbapenems were observed with a resistance rate of 16.13% in the ICU and 8.60% in the ward for Enterobacteria; 48.15% and 29.41% for Pseudomonas sp. and 82.98% and 58.33% for Acinetobacter sp. The microbial resistance observed in this study allowed the knowledge of the microbiological profile of the private hospitals to be analyzed.
