The severity of ICU-acquired pneumonia

Abstract

Much controversy exists about pneumonia in intensive care - especially, ventilator-associated pneumonia (VAP) - about its diagnosis and its attributable mortality. A better consensus exists about its prevention and its treatment. VAP occurs in already critically ill patients, and the relationship between preexisting organ dysfunction or failures and the severity of VAP has been recently highlighted. The role of the underlying disease should be considered as dominant, and this fact explains the paradox that exists between the high mortality of VAP and the relative minor effect of prevention measures on mortality. © 2013 Springer Science+Business Media New York.
