Pneumonia in the elderly. Special considerations in a special population.
Bacterial infections of the lower respiratory tract in the elderly may not be as atypical in presentation as traditional wisdom once held. Recent studies indicate that more than one in three elderly patients have fever, cough, and leukocytosis; nevertheless, some elderly patients present with none of the features typically associated with pneumonia. An important and consistent clinical difference between younger and older patients is the broader range of bacterial respiratory pathogens found in the elderly, including gram-negative bacilli such as Haemophilus influenzae, Proteus mirabilis, and Moraxella catarrhalis. Little is gained by the initial use of narrow-spectrum antibiotic therapy, and much may be lost. Parenteral third-generation cephalosporins and oral fluoroquinolones are active against the major pathogens and can be used for empirical broad-spectrum therapy. Recent trials indicate that results are equally good with agents of either type. Perhaps a third of elderly patients with pneumonia do not require or benefit from hospitalization. The availability of excellent new broad-spectrum oral antimicrobial agents makes treatment at home or in a nursing home an attractive way to avoid the costs and many complications of hospitalization for acute care of these frail patients.
