Microbiology (VAP)

Organisms

Gram-negative enteric bacilli (36%)

Primarily Klebsiella, E. coli, Enterobacter

Including MSSA and MRSA

Notes

Data from endotracheal or bronchoscopy cultures collected 48 hours or more after critical care admission in 2022

Enterococcus and Candida are commonly isolated in sputum cultures of hospitalized patients. They are generally considered colonizers and do not warrant antimicrobial therapy

Viruses (rhinovirus, influenza, parainfluenza, SARS-CoV-2) are increasingly recognized as a cause of VAP
