Abstract

Objective: The aim of this study was to investigate patients' inhaler competence and satisfaction with the Easyhaler® dry powder inhaler. Design: Two open, uncontrolled, non-randomised studies. Setting: Real life based on patients attending 56 respiratory clinics in Hungary. Participants: Patients with asthma or chronic obstructive pulmonary disease (COPD) (n = 1016). Intervention: In a 3-month study, adult patients (age range 18-88 years; n = 797) received twice-daily inhalations of formoterol via Easyhaler®, and in a consequential study (from one visit to another, with 3-12 months in-between) children and adolescents (age range 4-17 years; n = 219) received salbutamol via Easyhaler® as needed. Main Outcome Measures: Control of six Easyhaler® handling steps and patients' satisfaction with Easyhaler® based on questionnaires. Results: Correct performances (minimum and maximum of the six steps) were noticed after one demonstration in 92-98 % of the adults, 87-99 % of the elderly, 81-96 % of the children and 83-99 % of the adolescents. These figures had markedly increased at the last visit. Repeat instructions were necessary in 26 % of the cases. Investigators found Easyhaler® easy to teach in 87 % of the patients and difficult in only 0.5 %. Patients found Easyhaler® easy to learn and use, and the patients' (and parents') satisfaction with the inhaler was very high. Lung function values [forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF)] improved statistically significantly during the studies, indicating good inhaler competence and treatment adherence. Conclusion: Investigators found Easyhaler® easy to teach and patients found it easy to use, and their satisfaction with the device was high.
