The emergency department is becoming an increasingly important setting for the management of community-acquired pneumonia (CAP). This trend reflects the shortened hospital stays and decreased mortality among elderly hospitalized patients resulting from rapid administration of antimicrobials. In addition, decisions about the site of care (inpatient vs outpatient) and antimicrobial therapy frequently are made in the emergency department. ⋯ When hospitalization is required, early switch from intravenous to oral therapy, followed by early discharge, can be a highly successful strategy. Antimicrobials that are available in both intravenous and oral formulations, such as the newer fluoroquinolones (e.g., levofloxacin and gatifloxacin), can simplify switch therapy For outpatients, an initial long-acting parenteral dose of azithromycin, ceftriaxone, or levofloxacin followed by oral therapy is an effective protocol. In addition, use of a prediction rule to identify low-risk patients with CAP may help guide decisions about the need for hospital admission.
