Epidemiological profile of healthcare-associated infections caused by Carbapenemase-producing Enterobacteriaceae

Abstract

Objective: To study the epidemiological profile of Healthcare-associated Infections caused by Enterobacteria which carry the Klebsiella pneumoniae Carbapenemase gene (blaKPC) in the hospital environment. Method: A descriptive study was conducted in a private hospital in Belo Horizonte, MG, Brazil, which included all patients with infections caused by Enterobacteriaceae which carry the Klebsiella pneumoniae Carbapenemase gene. The data were collected by the Automated System of Hospital Infection Control and analyzed by descriptive statistics by the Epi Info 7 program. Results: Eighty-two (82) patients participated in the study. Klebsiella pneumoniae was the most frequent species (68%) isolated in blood (30%), bronchoalveolar lavage (22%) and urine (18%), while catheter-associated bloodstream infection (30%) predominated regarding topography. A case fatality rate of 62% is highlighted in evaluating the outcome. Conclusion: The resistance genes spread rapidly, limiting the antimicrobial options for treating infectious diseases. The epidemiological profile of Healthcare-Associated Infections found in this study can be prevented by prevention and infection control programs.
