In a potentially ground breaking study of healthcare-associated pneumonia (HCAP) patients, atypical pathogens were identified in 10% of cases!

Application to clinical practice: Add atypical coverage with a macrolide or respiratory fluoroquinolone for HCAP patients who have been in the community for any length of time.

The study also identified HCAP patients who may not require 3 'big gun' broad-spectrum antibiotics. This is a practice changing article for ED providers. For more analysis of the study, please note the bonus reading links below.
