Progress in Understanding and Managing Ventilator-Associated Pneumonia: Insights from Pathophysiology to Tailored Approaches

Category	Detail
Condition	Ventilator-Associated Pneumonia (VAP)
Key Mechanisms	Disruption of respiratory microbiome and host immune status due to mechanical ventilation and antibiotic exposure.
Target Population	Critically ill patients requiring invasive mechanical ventilation.
Care Setting	Intensive Care Unit (ICU)

VAP is associated with substantial morbidity and mortality.
Early antibiotic therapy does not consistently improve outcomes.
The respiratory microbiome plays a crucial role in VAP susceptibility.
Antimicrobial stewardship is essential to preserve microbiome homeostasis.
Rapid molecular diagnostics can improve targeted therapy but face implementation challenges.

Optimize antibiotic therapy by minimizing unnecessary exposure and considering delayed initiation until microbiological confirmation.

Therapeutic drug monitoring in both serum and alveolar fluid is recommended, though underexplored.

Patients with suspected VAP in the ICU.

Consider immune-phenotype-guided therapy for septic patients with VAP.
