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
Long-term clinical effects of an inhaler guidance DVD in patients with bronchial asthma
Objectives: Erroneous use of inhalers is a serious problem. Given the multitude of devices currently available, it can be difficult to convey the correct methods for their efficient use to patients. We previously generated an educational DVD that visually and audibly explains the proper use of all inhaler types available in Japan to provide inhalation guidance to patients. Herein, we report the 1-year follow-up of patients who received or did not receive the DVD guidance.
Methods: Sixty-nine bronchial asthma patients undergoing outpatient treatment who received inhalation guidance from a pharmacist using a standard package insert were randomly allocated to a DVD group (n=35) or a no-DVD group (n=34). Their current oral or inhalant drug regimens were unchanged. Various parameters were measured 12 months later. Frequencies of aggravation during the 12-month period were also determined.
Results: Compared with the no-DVD group, there were significant improvements in asthma control test scores, forced vital capacity, FEV1, impulse oscillometry, resonant frequency, induced sputum eosinophil count, and FeNO in the DVD group after 12 months. Pulmonary function and inflammation parameters improved significantly with the use of the instructive DVD in addition to the package inserts. The frequency of asthma aggravation significantly decreased in the DVD group during the 12-month study period, likely because inhalation procedures were performed accurately.
Conclusions: A DVD that provides accurate inhalation guidance enhances the quality of life of asthma patients and has substantial clinical ramifications. Thus, this tool would be beneficial for patients in Japan and worldwide
A prospective study exploring the predictors of response to benralizumab in patients with refractory bronchial asthma
A prospective study exploring the predictors of response to benralizumab in patients with refractory bronchial asthma
OBJECTIVE: This study aimed to evaluate the predictors of response to benralizumab therapy in patients with refractory bronchial asthma. METHODS: After 16 weeks of benralizumab therapy, 32 patients with refractory bronchial asthma were assigned to two groups based on the response to treatment as indicated by changes in the asthma control test score (responders and non-responders) and evaluated for clinical characteristics. RESULTS: Overall, 25 responders and 7 non-responders were identified at week 16. Logistic regression analysis identified a peripheral eosinophil count of >300/μL during benralizumab treatment and a maximal peripheral eosinophil count of >300/μL in the past year as predictors of response. CONCLUSIONS: The predictors of response to benralizumab included a peripheral eosinophil count of >300/μL during treatment and a maximal peripheral eosinophil count of >300/μL in the past year. These findings could improve patient selection and reduce medical costs in the future
