Treatment of community-acquired pneumonia in an ambulatory setting.

Community-acquired pneumonia continues to be a significant cause of morbidity and mortality despite broad-spectrum antibiotics and advances in critical care. Frequently, the diagnosis is confounded by coexisting cardiac or pulmonary conditions. Recognition of patients at risk for complications from pneumonia is critical when making the decision of how and where to treat. This review summarizes the diagnosis and treatment of community-acquired pneumonia with oral antibiotics in an outpatient setting. Specific pathogens and clinical presentations in certain at-risk populations are highlighted. Also presented are validated algorithms for evaluating and identifying patients who may be at risk for serious complications of pneumonia and require treatment in an inpatient setting.
