Answer

Computed tomography (CT) scanning or spiral CT scanning may be useful in differentiating mimics from actual nosocomial pneumonia. For example, blood cultures that are positive for MSSA/MRSA in a febrile intubated patient are not diagnostic of MSSA/MRSA nosocomial pneumonia/ventilator-associated pneumonia (VAP). The diagnosis of MSSA/MRSA community-acquired pneumonia/nosocomial pneumonia is based on the clinical presence of fever, cyanosis, hypotension, and rapid cavitation of infiltrates (

Since only approximately 25% of changes documented on portable chest radiographs of ventilated patients represent an infectious process, follow-up CT scanning should be obtained in this situation.
