Abstract
Pneumonia is a parenchymal lung infection that usually shows as an infiltrate on chest films, except in those with severe dehydration or in the patient with acquired immunodeficiency syndrome (AIDS).1 Incidence is highest in the young (less than 5 years) and old (especially nursing home residents). With about 60,000 deaths yearly, pneumonia is the sixth leading cause of deaths. There are an estimated 4 million cases of pneumonia in the United States yearly, with up to 600,000 hospital admissions.2 For the family physician, pneumonia ranks as the 25th most common problem seen and accounts for 0.8% of office visits. A family physician with 2000 patients would see, on the average, 25 to 30 patients each year with pneumonia. About 20% of outpatient pneumonia patients require admission to the hospital, but most of the epidemiologic data on pneumonias are from inpatients. There are few controlled clinical trials on outpatient pneumonia treatments.
