Breathing Retraining for Asthma Trial of Home Exercises for Teenagers (Breathe4T); Re-purposing, Refining and Feasibility - Stage 3

This trial will address the impaired quality of life of young people with asthma, despite appropriate medicines. Research shows that young people report needing to calm themselves down during an asthma attack to control their breathing. Although physiotherapist- delivered breathing retraining programmes now have a clear evidence base in adults with asthma, improving quality of life, there is a lack of evidence assessing its use in younger patients. The investigators have redesigned an adult training package to make it appropriate for young people and will now assess how effective such an intervention would be in this population. This study will include young people (12-17 years) with physician diagnosed asthma. The repurposing, optimisation and acceptability of the intervention in the adolescent age group has been undertaken in Stages 1 and 2 of the Breathe 4 Teens (BREATHE4T) project. A self-guided, breathing retraining digital intervention has been developed, delivered via a mobile friendly, online platform.

The current study is a randomised, controlled feasibility trial and will provide the necessary information for a substantive cost-effectiveness trial. Participants with access to the intervention will be compared to a usual care group. Asthma and quality of life of both groups will also be assessed at baseline, 2-month and 6-month time points. At the end of the 6 months, the control group will also be given access to the website.

The online nature of this study allows recruitment from across the United Kingdom. Recruitment methods would include primary care, hospital clinics, social media and posters. AsthmaUK will also provide publicity to assist recruitment.
