Plain English Summary

Background and study aims
The UK has one of the highest rates of asthma in the world. Nearly 6 in every 100 of the UK population have asthma, or 5.4 million people, most of whom are managed by GP surgeries. Hospital admission and death rates for asthma have dropped in the last decades of the last century, but these improvements have stalled since 2000. Early death from asthma was 1.5 times as high in the UK as in the rest of the EU in 2008, with around 1000 to 1200 deaths a year recorded since 2000. It is estimated that 9 out of 10 deaths could be prevented. Asthma is associated with high numbers of admissions and emergency department attendances, and it is estimated that 7 in 10 of these could have been prevented by appropriate early treatment and self-management. Poor control of asthma symptoms is common and the majority of asthma patients in the UK suffer potentially avoidable symptoms and reduction in their quality of life.
Although the UK leads the world in providing guidelines for asthma management, these have been poorly implemented. People with asthma do not receive evidence-based treatment and management, particularly individual action plans, which are known to improve outcomes. Patient education and proactive self-management have been convincingly shown to improve clinical outcomes in asthma and have been recommended in guidelines for 20 years.
Increasingly widespread access to the internet and mobile phones means that healthcare Digital Interventions (DIs) are accessible to the majority of patients, and can be used to provide information and support at any time the patient needs it . DIs can empower patients by providing better access to personalised information, and support for active involvement in treatment and self-management. A large analysis of multiple research studies found a small but meaningful positive effect of DIs on health-related behaviours. Another review of research found evidence that computer-based health interventions for those with chronic health conditions significantly improved knowledge, health behaviours and clinical outcomes. DIs have the potential to make significant savings by automating routine aspects of patient education, monitoring and support, freeing up health professional resources for when patients most need them. These savings can play an essential part in meeting the NHS Quality, Innovation, Productivity and Prevention (QIPP) agenda to achieve increased efficiency gains despite the growing demand created by an expanding and ageing population.
The main aim of the My Breathing Matters trial is to assess the feasibility, acceptability, effectiveness and cost-effectiveness of a DI in primary care for the self-management of asthma, in comparison to usual care (with provision of standard patient information materials produced by the charity Asthma UK).

Who can participate?
Adults who are receiving medication for asthma and whose asthma is affecting their life

What does the study involve?
People who are interesting in taking part in the study will complete the questionnaire and consent form provided and post it back to the research team in the freepost envelope provided. If they are eligible for the study, a research nurse will contact the participant to arrange an appointment to take part in the first part of the study. At this appointment the nurse will check the participant's asthma, and ask them to answer some questions about their breathing. If the participant is able to take part in the study, the nurse will put them in a group by chance (the same as flipping a coin).
One group will use the My Breathing Matters website at home. The other group will continue to receive usual care from their GP practice. Those who are in the group using the My Breathing Matters website can use the website as much or as little as they like. They will be given access to lifestyle modules, which aim to boost the ways that they can help their breathing. There will be the option to take part in a telephone interview later on in the study, to talk about experiences of My Breathing Matters. Participants can decide if want to do this when the investigators ask them, after they have tried My Breathing Matters.
For all groups, the study will last for 12 months. 3 months after joining the study all participants will be asked to answer some questions about their breathing (these will be questionnaires that will be posted to them, and they will be provided with a stamped, pre-addressed envelope to return them in). 12 months after joining the study, participants will have an appointment with a research nurse, to check their asthma.

What are the possible benefits and risks of participating?
The researchers cannot guarantee that taking part in this study will benefit patients. However, patients may find that the website has a positive impact on their breathing and general well-being, which has been shown in some previous studies. Patients will also receive a £10 gift voucher for taking part.
The investigators think there is very little risk of harm in taking part, and previous studies have found no negative events. My Breathing Matters is not meant to replace the care provided by GPs and patients should seek advice from GPs if they experience any problems. The main disadvantage is that the research will take up some of patients' time. They will need to attend two appointments (lasting 1 hour each) with a research nurse and complete some questionnaires sent to them in the post. Participants can use as much or as little of the website as they like.

My Breathing Matters is a digital intervention for the self-management of asthma, consisting of pharmacological support, (advice about asthma reviews and personal asthma action plans, information about medication and side effects) and non-pharmacological components (stress reduction, online versions of breathing retraining courses shown to be acceptable and feasible) and optional user-selected lifestyle modifications.

All interested patients will be screened by their Asthma Quality of Life Questionnaire score. All suitable patients will be invited to a baseline consultation with a research nurse at their local GP practice. The baseline appointment lasts approximately 30 minutes and includes consent, clinical and questionnaire measures. All eligible patients will be randomised at the baseline appointment to either usual care or the intervention arm of the study (randomised in a 1:1 ratio, stratified block randomisation by the average value of AQLQ scores in the BREATHE trial). All eligible patients receive standardised asthma advice – Asthma UK information leaflet.

Those patients randomised to the intervention arm will be given instructions for logging onto the intervention and have access to the online My Breathing Matters intervention for 12 months, and invited to take part in interviews to discuss their experiences using the intervention after 3 months. Those in the usual care group do not have access to My Breathing Matters (until they have completed their 12 month follow up appointment).

After 3 months all participants in both arms are asked to complete postal questionnaires, and then after 12 months all patients are invited to a second appointment with the research nurse to cover clinical and questionnaire measures.
