Prognostic Impact of Early Appropriate Antimicrobial Therapy in Critically Ill Patients With Nosocomial Pneumonia Due to Gram-Negative Pathogens: A Multicenter Cohort Study

In this study, EAAT was not associated with a reduced day 28 mortality, a faster resolution of organ failure, a higher day 14 clinical cure rate, or a shorter time to MV weaning or ICU discharge in critically ill patients with HAP, vHAP, or VAP due to GNB. However, a prognostic benefit from EAAT cannot be ruled out due to lack of statistical power.
