If aspiration pneumonia is acquired in a hospital, what additional coverage is often considered?

• A. Anti-pseudomonal and/or MRSA coverage
• B. Only anaerobic coverage
• C. Antifungal coverage
• D. No change to regimen

Answer: (A)

In hospital-acquired aspiration pneumonia, the pathogens tend to be more resistant and include organisms like Pseudomonas aeruginosa and MRSA, so empiric treatment is broadened to cover both. That typically means using an anti-pseudomonal agent (such as a beta-lactam with anti-pseudomonal activity or a carbapenem) and adding MRSA coverage (like vancomycin or linezolid) upfront, with de-escalation once culture results are known. While anaerobes can be involved in aspiration, narrowing therapy to anaerobic coverage alone would miss these important aerobic and resistant pathogens seen in the hospital setting. Antifungal coverage isn’t routinely added unless specific risk factors for fungal infection are present. No change to broad coverage would risk inadequate initial therapy in a hospital environment where resistant bacteria are more common.
