Scripps local data suggests low incidence of MRSA (3%) and Pseudomonas aeruginosa (3%)

Routine anaerobic coverage not indicated unless empyema or abscess

Blood and sputum cultures should be ordered when considering broad spectrum coverage against MRSA and P. aeruginosa

• De-escalate antibiotics if MRSA/P. aeruginosa not isolated at 48-72 hours
• Negative MRSA nasal cultures can be used to de-escalate anti-MRSA therapy
