Pneumonia that occurs 48 hrs or more after admission and was not present at the time of admission
Antimicrobial therapy is not indicated for aspiration pneumonitis from micro-aspiration due to vomiting
Aspiration pneumonia from swallowing difficulties does not require additional anaerobic coverage (i.e. metronidazole) since oral anaerobes (i.e. Peptostreptococcus) are covered by most beta-lactams
Collect blood cultures and respiratory culture (sputum, endotracheal aspirate or bronchoscopic samples), ideally BEFORE antimicrobials are started
