Insights
A brief video improved children's inhaler technique immediately after a pediatric visit, but the effect faded by one month. This asthma intervention did not significantly boost self-efficacy or control.
Area of Science:
- Pediatric Pulmonology
- Asthma Management
- Health Education
Background:
- Proper inhaler technique is crucial for effective asthma management in children.
- Brief educational interventions may offer a scalable approach to improve adherence and outcomes.
- Existing research highlights challenges in maintaining long-term adherence to proper inhaler use.
Purpose of the Study:
- To evaluate the immediate and one-month effectiveness of a brief video intervention on pediatric asthma inhaler technique.
- To assess the impact of the video intervention on children's inhaler self-efficacy and asthma control.
- To provide data for future studies on optimizing asthma education delivery in clinical settings.
Main Methods:
- Pilot randomized controlled trial involving 91 children (ages 7-17) with persistent asthma.
- Intervention group watched a 3-minute metered-dose inhaler (MDI) video; control group watched a nutrition video.
- Inhaler technique assessed using a validated checklist immediately post-intervention and at one-month follow-up.
Main Results:
- Significant immediate improvement in MDI technique observed in the intervention group (mean=1.12 steps).
- This improvement in inhaler technique was not sustained at the one-month follow-up.
- No significant differences were found in inhaler self-efficacy or asthma control between groups.
Conclusions:
- A brief video intervention can effectively improve children's inhaler technique in the short term.
- Sustaining the benefits of inhaler technique interventions requires further investigation, possibly through booster sessions.
- Future research should explore strategies to maintain improved inhaler technique for better long-term asthma management.
Objective:
This primary objective of this pilot randomized, controlled trial was to determine whether a brief video intervention delivered after a pediatric office visit could improve inhaler technique in children with asthma immediately and one month later. The intervention's effect on children's inhaler self-efficacy and asthma control was also evaluated.
Methods:
Children (n=91) ages 7-17 years with persistent asthma were recruited at two pediatric practices in North Carolina. Eligible children demonstrated their inhaler technique for metered dose inhalers (MDIs) either with or without a spacer. A trained research assistant used a validated inhaler technique checklist to record which steps children performed correctly. After a regularly scheduled office visit, children were randomized to watch either a 3-min MDI video (intervention group) or a nutrition video (control group) in English or Spanish. Children's technique was assessed again after watching the video and one month later.
Results:
Children were primarily male (56%) and non-White (60%). When compared with the control group, children in the intervention group demonstrated a significant improvement in MDI technique post-intervention [mean=1.12 steps, 95% CI (0.73, 1.50)] but the improvement was not sustained at 1-month follow-up. The intervention did not lead to significant improvements in inhaler self-efficacy or asthma control.
Conclusions:
A brief video intervention offered during pediatric clinic visits can lead to immediate improvements in children's inhaler technique. Future studies should evaluate whether booster training videos can help maintain improvements in children's inhaler technique over time.
