Effectiveness of training patients using DVD in the accurate use of inhalers for the treatment of bronchial asthma.

BACKGROUND: Inhalants are the standard treatment for patients with bronchial asthma. Inaccurate inhaler use leads to inadequate therapeutic effects and unnecessary dosage increases. However, it is a challenge for practitioners to master the various devices available and train patients on the accurate use of inhalers. Thus, establishing a system to instruct patients on how to accurately use inhalers is essential. We prepared a DVD and accompanying user manual explaining the operation of each inhaler device used in Japan. This pilot study aimed to examine the efficacy of these materials.
METHODS: The subjects were 33 outpatients with bronchial asthma who received treatment in our facility for asthma and had already received conventional inhalant training. The oral medication and inhalants used by the patients were not changed. The patients were randomly assigned to a DVD viewing group or non-viewing group; various parameters were comparatively examined after 4 weeks.
RESULTS: Significant improvements in Asthma Control Test scores, inhalation technique, forced vital capacity, forced expiratory volume in 1 s, impulse oscillometry resonant frequency, and induced sputum eosinophil count were observed in the DVD viewing group at 4 weeks post training.
CONCLUSIONS: Pulmonary function and inflammatory parameters improved significantly in the DVD viewing group. These findings suggest that unnecessary step-up of asthma treatment can be avoided, leading to treatment cost reduction. Training patients with asthma in accurate inhaler use improves quality of life and therefore has great clinical significance. Hence, this method should be used more extensively in Japan and worldwide.
