    296 adults 50–92 years of age (mean age 66 y, 52% women) who had physician diagnosed asthma, medication use suggestive of moderate-to-severe asthma, bronchodilator reversibility (>8% of baseline FEV1), and demonstrated ability to keep a daily symptom diary.

    Embedded ImageIntervention:

    symptom monitoring plus PFM (n = 149) or symptom monitoring only (n = 147). All patients attended four 90 minute small group sessions that included development of personalised action plans and review of asthma diaries. Patients were instructed in …
