Bronchodilator response does not associate with asthma control or symptom burden among patients with poorly controlled asthma

This study found that bronchodilator response (BDR) was not associated with patient-oriented outcomes of asthma control or symptoms. This finding is important because it questions the continued use of BDR in clinical assessment, and further research will lead to improved tracking and treatment of patients with asthma, using tests and scores that more accurately reflect their current disease state. This study was performed by the American Lung Association Airways Clinical Research Centers.
