Adapting Body Reprogramming for Severe Asthma: a Feasibility Study

There are many symptoms associated with severe asthma, not all of them asthma specific (e.g. mental fog, fatigue, unexplained pain), and the relationship between these symptoms and quality of life is complex.

Body reprogramming (BR) is another non-drug intervention originally developed for fibromyalgia patients. BR aims to to improve health and wellbeing in a personalised way, with evidence-based lifestyle changes. The frequency and severity of the non-asthma specific symptoms in severe asthma are similar to those experienced by patients with fibromyalgia. Therefore, the investigators propose that BR may be a suitable non-drug intervention for severe asthma patients who report many non-asthma specific symptoms. This intervention includes optimising knowledge of disease management, physical activity, relaxation and other psychological and biological lifestyle changes which aim to improve wellbeing and mood, and this could lead to better self-management of complex symptoms in asthma patients.

Phase 1 Eligible patients attending a severe asthma service at an Royal Devon and Exeter (RD\&E) Hospital will be identified by a health professional familiar to them and invited to take part in the study by post, including a Participant Invitation, Information Leaflet and consent form. The Invitation Letter and Patient Information Leaflet will include instructions to read the material carefully and to bring the consent form with them to their next scheduled clinic appointment.

Participants will be asked to attend four weekly sessions of Body Reprogramming via group video call using Zoom. Each session will include up to 8 patients and will consist of a 25-30 minute live presentation delivered by a researcher from the University of Plymouth. At the end of the presentation, there will be an opportunity to ask questions or raise points of interest. Each session will include a 'practice and report back next week' instruction, and participants will be encouraged to provide written after completing all sessions. feedback before Session topics will include: conceptualising severe asthma, stress and happiness, movement and exercise, and eating and asthma triggers.

Demographics (e.g. age) and clinical data (e.g. current drug treatment) will be collected from participants' hospital notes at the start of the programme. Participants will be asked to complete a series of questionnaires for the first and last weeks of Body Reprogramming. These will be posted to participants and returned to the research team using an enclosed Freepost envelope. Questionnaires will include: the Severe Asthma Questionnaire (SAQ), the General Symptom Questionnaire (GSQ), the Positive And Negative Affect Schedule (PANAS), the Asthma Control Questionnaire. At the end of the course participants will be asked to complete the much shorter General Symptom Questionnaire-Asthma (GSQ-A) instead of the full GSQ. In addition to these questionnaires participants will also be asked to complete and return the Global Rating of Change Questionnaire (GRCQ) and the Friends and Family Test after completing the intervention. These should take no longer than 20 minutes to complete.

Following the course, participants will be invited to attend a focus group with up to 5 other participants via video call or a one to one interview also via video. This time will be used to discuss participants experience of Body Reprogramming, including any problems they may have faced. This will last for up to 2 hours and will be recorded using a voice recorder for transcription and analysis by the research team.

Analysis will include generation of summary statistics and mean differences for numerical data, including the number of people who were invited and attended each BR course.

Thematic analysis of transcribed focus group data will be used to inform any changes which need to made to improve the programme before Phase 2.

Phase 2 Before commencing a biologic treatment for severe asthma in normal clinic care, patients are reviewed by a multidisciplinary team responsible for their care, and the participating hospital's Principal Investigator will identify eligible participants. Participant recruitment will then proceed as outlined in Phase 1.

A modified GRCQ will completed by participants at the end of the intervention in phase 2. The changes to the wording of GRCQ are to take into account that participants have started a new treatment (the biologic drug) and completed BR. Except for this change, the same questionnaire data will be collected at the same time-points in this phase.
