This study highlights the significant prevalence of Pseudomonas aeruginosa (PA) as a major bacterial pathogen causing ventilator-associated pneumonia (VAP) in ICU patients, with a high detection rate of 71.7% in tested patients, emphasizing the need for targeted screening and treatment strategies.

High PA prevalence in VAP:
The study found a very high rate of PA detection in VAP cases, indicating its significant role as a causative agent in ICU patients with VAP.

Colistin efficacy:
Despite concerns about resistance, the study observed a substantial proportion (66.7%) of PA isolates remaining sensitive to colistin, suggesting its potential as an effective treatment option.

Antibiotic stewardship:
Due to the high prevalence of PA and the need for appropriate antibiotic selection, the study emphasizes the importance of robust antibiotic stewardship programs to guide targeted therapy and minimize resistance development.

Microbial resistance monitoring:
Continuous monitoring of bacterial resistance patterns is crucial to ensure optimal treatment strategies against prevalent pathogens like PA.
