Nosocomial (i.e., originating or taking place in a hospital) pneumonia is the leading cause of death from acquired nosocomial infections. The estimated prevalence of nosocomial pneumonia in intensive care units ranges from 10% to 65%, with fatality rates of 13-55%. ⋯ Recent investigations have provided new insights into the pathogenesis of VAP, and improved techniques have been developed for its diagnosis. Most important, emerging clinical data now suggest that new management strategies for VAP, including more specific indications for antimicrobial use, may significantly improve patients' outcomes.
