Prevalence, Risk Factors, and Mortality for Ventilator-Associated Pneumonia in Middle-Aged, Old, and Very Old Critically Ill Patients*

Abstract

In this multicenter cohort study, ventilator-associated pneumonia did not occur more frequently among elderly, but the associated mortality in these patients was higher. New temperature rise was less common in elderly patients with ventilator-associated pneumonia, whereas more episodes among elderly patients were caused by Enterobacteriaceae.
