The aim of this study was to evaluate the impact of a new patient education programme on adults with asthma. This self-management programme included an individual assessment of patient's needs and two educational group sessions. Teaching methods and session content are described as well as caregivers training programme. The training sessions included a written asthma action plan based on symptoms and personal peak expiratory flow. Patients (n = 238) aged from 18 to 60 years were allocated to the intervention (group A) or control group (group B). Patients filled during 1 year a daily diary and questionnaire and they were administered telephone interviews. 127 patients were included in the treatment program and 111 in the control group. There was a significant improvement in the educated group with regard to symptoms free days (P = 0.03), number of awakenings (P = 0.04), consumption of corticosteroids (P = 0.03), consumption of beta2-agonists (P = 0.03), and quality of life score (P = 0.01). In conclusion, this study validates a specific educational approach named "un souffle nouveau".
