Office management of the patient with chronic cough.

Chronic cough is a common complaint in the ambulatory setting and can result in significant compromise in quality of life and, uncommonly, is a presenting symptom of serious or life-threatening disease. Although there are many potential causes, an organized approach to diagnosis that may include therapeutic trials of select medications can establish the diagnosis in over 90% of presenting patients. Management hinges on accurate etiologic diagnosis. Consultation with a pulmonologist, otolaryngologist, or allergist is indicated in selected cases where diagnosis is unclear or specific therapy is mandated.
