Impact of nosocomial pneumonia on the outcome of mechanically-ventilated patients.

: BACKGROUND: Nosocomial pneumonia (NP) is a common complication in mechanically-ventilated patients and is considered to be one of the most common causes of morbidity and mortality. However, assessment of the associated mortality is not staightforward as it shares several risk factors with NP that confound the relationship. The aim of this study was to evaluate the impact of NP on the mortality rate in an intensive care unit.
