The effect of training of metered-dose inhaler technique on asthma control and quality of life in children with asthma: a randomized trial

ABSTRACT The purpose of the study was to determine the effect of two different training styles (with brochure or video) with follow-ups for metered-dose inhaler (MDI) technique on asthma control and quality of life in children with asthma. Training for MDI technique was provided to 66 children (age 7–11 years) by using an MDI Technique Checklist. On the day of training and 4 weeks later, asthma control level (as assessed using the Childhood Asthma Control Test-C-ACT) and quality of life (as assessed using the Pediatric Asthma Quality of Life Questionnaire-PAQLQ) of the children were assessed. MDI Technique Checklist, C-ACT, and PAQLQ scores showed a statistically significant increase in both groups (p <.001), and technique reached the maximum score in the video group. Two different training methods on MDI technique provided the children with improved asthma control and quality of life. Follow-ups should be continued either to maintain or to improve skills.
