Chronic obstructive pulmonary disease (COPD) is a heterogeneous group of slowly progressive diseases characterized by airflow obstruction that interferes with normal breathing (1). In 2005, approximately one in 20 deaths in the United States had COPD as the underlying cause. Smoking is estimated to be responsible for at least 75% of COPD deaths (2). Excess health-care expenditures are estimated at nearly $6,000 annually for every COPD patient in the United States (3).
