Abstract

Background: Hospital-acquired pneumonia is a very serious disease, the most common among nosocomial infections, the rate of treatment failure is high due to the increasing antibiotic resistance of bacteria. Objectives: Describe the characteristics of pathogenic bacteria and determine antibiotic resistance rates of bacteria isolated on patients with hospital-acquired pneumonia at Can Tho General Hospital. Materials and methods: A cross-sectional descriptive study, performed on the medical records of hospital-acquired pneumonia patients treated as inpatients at the Intensive Care Unit - Anti-Poison and General Internal Medicine Department of Can Tho General Hospital in 2021-2022. Results: Out of 102 medical records, the Common pathogens are Klebsiella pneumoniae 44%, Acinetobacter baumannii 27%, Escherichia coli 12% and Pseudomonas aeruginosa 17%. Gram-negative bacteria are highly resistant to the following groups: cephalosporins, carbapenems and fluoroquinolones. K. pneumonia was still sensitive to amikacin (52%), A. baumannii was resistant to most antibiotics except colistin (sensitive 100%), P. aeruginosa is 100% sensitive to colistin, E. coli is quite sensitive to amikacin 100%, carbapenem over 60%, piperacillin/tazobactam 60%. Conclusions: Gram-negative bacteria are the main causative agents of hospital-acquired pneumonia and most of these bacteria are now highly resistant to cephalosporins, carbapenems, and fluoroquinolones.
