Diagnosis and inhalation techniques in uncontrolled pediatric asthma

Abstract

Background: There are a certain number of children with uncontrolled asthma who do not improve even with guideline-based treatment.

Objective: To clarify the examination for complications, the effects of confirming and instructing inhalation techniques, and the use of biologics in children with uncontrolled asthma.

Methods: Children who were prescribed bronchial asthma medication at our hospital during the past 8 years were included in the study. Of these children, those who were under long-term management of asthma treatment STEP 3 or higher were selected, and the examination, diagnosis, and treatment were reviewed.

Results: 485 children were receiving STEP 3 or higher treatment, and 110 of them were assigned to uncontrolled asthma. Most of the cases were complicated with chronic sinusitis or gastroesophageal reflux disease, but rare diseases such as diffuse panbronchiolitis were also observed. Four children were treated with biologics. Approximately 70% of children with uncontrolled asthma were able to step down in treatment after patient education such as confirming and instructing on proper inhalation techniques.

Conclusion: This study reaffirms the importance of examining complications and patient education before intensifying the treatment in children with uncontrolled asthma.
