Nosocomial pneumonia in the noncritical care setting.

The optimal approach to the recognition, management, and prevention of nosocomial pneumonia is evolving. A broad spectrum of potential pathogens is recognized in the hospital setting, and more invasive procedures have been developed in attempts to improve diagnostic accuracy. Newer, broad spectrum antimicrobial agents are continually introduced, yet the presence of resistant organisms is increasingly recognized. The reports released in the past year show physicians are making advances toward gaining a better understanding of this common infection.
