Objective: To determine the rate of pathogens and antibiotic resistance of gram-negative bacteria in hospital acquired pneumonia patients at the Respiratory Department, Thong Nhat hospital from April 2022 to April 2024.
Methods: Prospective, descriptive.
Results: Pathogens mainly gram-negative bacteria 83.6% (K. pneumoniae 28.4%; A. baumannii 19.4%; P. aeruginosa 17.9% and E. coli 10.4%); S. aureus 16.4%. All strains are resistant to cephalosporines and fluoroquinolones 60-100%. K. pneumoniae, P. aeruginosa and A. baumannii are resistant to 45-70% with imipenem and meropenem.
Conclusion: The leading cause of hospital acquired pneumonia is gram negative bacteria. K. pneumoniae, P. aeruginosa and A. baumannii are highly resistant to carbapenems.
