Symptomatic burden of COPD for patients receiving dual or triple therapy

Abstract

Although patients who consult their physicians more frequently than average may be overrepresented because of the observational design of this study, we report that unmet needs remain for patients with COPD, despite the use of dual or triple therapy. A percentage of patients with COPD reported major symptom burden affecting their daily living and causing a large impairment in the health status, regardless of treatment adherence.
