DVD Versus Physiotherapist-Led Inhaler Education: A Randomised Controlled Trial

Area of Science:

• Pediatric respiratory medicine
• Health education technology

Background:

• Correct inhaler technique is crucial for effective respiratory medication delivery in pediatric patients.
• Inhaler misuse is common, leading to suboptimal therapeutic outcomes.
• Innovative educational methods are needed to improve patient and caregiver adherence and technique.

Purpose of the Study:

• To evaluate the efficacy of Digital Versatile Disc (DVD) based inhaler instruction compared to traditional individual education.
• To assess the feasibility of a standardized inhaler technique outcome measure in a clinical research setting.
• To compare changes in inhaler technique, knowledge, and self-efficacy between DVD and individual education groups.

Main Methods:

• A randomized controlled trial was conducted in a pediatric ward.
• Participants (new or existing pediatric inhaler users) were randomized to receive education via DVD or individual instruction from a physiotherapist.
• Inhaler technique, self-efficacy, and knowledge were assessed immediately post-intervention and at a three-month follow-up.

Main Results:

• No statistically significant differences were observed between the DVD and individual education groups in terms of inhaler technique, self-efficacy, or knowledge at any assessment point.
• The developed inhaler technique outcome measure proved feasible for use in research.
• Twenty-one participants completed the study.

Conclusions:

• DVD-based inhaler education is an effective and equivalent alternative to individual instruction for teaching pediatric inhaler technique to caregivers.
• This approach offers a scalable and potentially cost-effective method for improving adherence and therapeutic outcomes in pediatric respiratory care.
