Chronic obstructive pulmonary disease (COPD) is a highly prevalent disease whose sufferers consume a large amount of resources. Among community-dwelling Medicare beneficiaries, 12% reported that they had COPD in 2002. For clinicians, differentiating COPD from asthma may be difficult, but among patients with COPD and asthma, approximately 20% have both conditions. The economic impact of concomitant asthma and COPD is potentially large but has not been studied.
