Multicenter Study Clinical Trial
Difficulties in differential diagnosis of COPD and asthma in primary care.
Chronic obstructive pulmonary disease (COPD) and asthma treatment must be based on appropriate diagnosis. However, patients receiving inhaled therapy in primary care may not be accurately diagnosed according to current guidelines. ⋯ Most patients can be classified as having COPD or asthma by primary care physicians. The use of the two questionnaires did not provide a better differential diagnostic compared with symptoms and spirometry with a BDT. Misdiagnosis may lead to inadequate treatment.
