Community-Acquired Pneumonia in the Elderly:

May 01, 2003

ABSTRACT: In addition to advanced age, factors such as comorbid illness and debility determine the risk of community- acquired pneumonia (CAP). Many elderly persons do not have the classic symptoms of CAP; instead, they may present with confusion, lethargy, tachypnea, anorexia, or abdominal pain. Even with thorough investigation, an infectious pathogen can be identified in only about half of patients. In addition to the causative organisms for pneumonia in younger adults, elderly persons are at risk for infection with organisms such as Haemophilus influenzae, Staphylococcus aureus, enteric gram-negative bacteria, and anaerobes, and for polymicrobial infection. Prompt empiric treatment is essential. Recommended initial therapy choices include a ß-lactam agent with a macrolide, or an antipneumococcal fluoroquinolone.
