Plain English Summary
Background and study aims
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that cause breathing difficulties. The course of COPD is characterised by a worsening of symptoms or exacerbations requiring a change of medication, more intensive treatment, and possibly an admission to hospital. What would be of greater value to the health service would be the identification of indicators of such worsening in order to help patients manage their condition better. Therefore, this study aimed to find out whether it is possible to predict a worsening of COPD symptoms using device worn on the body.
Who can participate?
Patients aged 40 years or above with COPD
What does the study involve?
Participants are recruited from either hospital wards or from a routine assessment for pulmonary rehabilitation. Patients will then be given information about the study. Individuals recruited from the wards complete some questionnaires and measures of physical function before they leave hospital. Individuals recruited from pulmonary rehabilitation assessments complete the same measures during a study visit. All participants are asked to complete a symptom diary at the end of each day and to wear a vest-like monitor which measures their heart rate, breathing rate, skin temperature and physical activity for 6-7 weeks. After this period, participants attend a final visit to repeat the previous measures.
What are the possible benefits and risks of participating?
There are no direct benefits to participants taking part in this study due to its observational nature; however, participants will be sent a summary of their data on request. There are no known risks to participants taking part in this study and the research team are happy to reimburse travel costs.
Where is the study run from?
Glenfield Hospital, University Hospitals of Leicester NHS Trust (UK)

Study information
Scientific title
SYMPHONY (SYMptoms and PHysiology to Observe and uNderstand activitY): Using continuous, passive, non-invasive wearable technology to understand the interactions between physiology, behaviour, the environment and exacerbations of chronic obstructive pulmonary disease (COPD)
Acronym
SYMPHONY (SYMptoms and PHysiology to Observe and uNderstand activitY)
Study hypothesis
1. On days with elevated symptom severity, breathing rate, heart rate and skin temperature will be higher and physical activity will be lower than days with stable or milder symptom severity
2. It will be possible to predict symptom-based and event-based exacerbations of COPD using the physiological and behavioural information obtained from wearable technology
3. It will be feasible to collect behavioural and physiological data using wearable technology
4. The wearable technology will be acceptable to patients

Condition
Chronic obstructive pulmonary disease (COPD)
Intervention
This prospective study has two groups; patients admitted for an acute exacerbation of COPD (acute group) and patients with stable disease (Stable group). The acute group will be recruited from hospital wards following admission for an acute exacerbation of COPD. The stable group will be recruited from hospital-based and community-based pulmonary rehabilitation assessment appointments as part of the usual care pathway.
For the acute group, patients admitted for an acute exacerbation of COPD will be screened by COPD Specialist Nurses for eligibility. Eligible patients will then be provided verbal and written information about the study. A member of the research team will speak to the patient to determine whether they wish to participate in the study. Written informed consent will be obtained. Participants will be asked to complete some questionnaires (outlined below), and their balance, walking speed and ability to rise from a chair will be assessed. Following discharge, participants will be asked to wear a light-weight device made from thin, breathable fabric for 6 weeks (±3 days for patient preference). Participants will be asked to wear this during waking hours only (except any water-based activities). Participants will be asked to charge the device overnight or during water-based activities for at least 30-60 minutes each day. Participants will be provided with cleaning equipment and instructions. A member of the research team will contact participants every fortnight by telephone to check how they are getting on.
For the stable group, a member of the pulmonary rehabilitation team will provide written and verbal information about the study during their pulmonary rehabilitation assessment visit as part of usual care. A member of the research team will contact eligible participants by telephone to find out if they would like to take part in the study and answer any questions they may have. This phone call may occur less than 12 hours after the completion of their pulmonary rehabilitation assessment if they are due to start pulmonary rehabilitation within two weeks of that date. People wishing to take part will be asked to attend the Respiratory Biomedical Research Unit at Glenfield Hospital. The visit will last no longer than 1 hour. Following informed consent, participants will be asked to complete some questionnaires (outlined below), and their balance, walking speed and ability to rise from a chair will be assessed. Participants will be asked to wear the chest-worn device for 1 week in order to obtain pre-rehabilitation (baseline) information about their physical activity and physiology. If the time between study visit and starting rehabilitation is less than 1 week, the participant will be asked to wear the device for that duration (e.g. 4 days). Once participants begin their pulmonary rehabilitation programme, they will be asked to wear the device for 6 weeks (the length of the pulmonary rehabilitation programme) with the same instructions as the acute group. Participants who do not go on to complete pulmonary rehabilitation will still be allowed to remain in the trial if they wish.
All patients will be asked to monitor their exacerbations using the EXAcerbations of Chronic pulmonary disease Tool (EXACT) patient-reported outcome (PRO) daily diary. The diary assesses breathlessness, cough and sputum, chest symptoms, difficulty bringing up sputum, feeling tired or weak, sleep disturbance, and feeling scared or worried about their COPD. Participants will be given an electronic device or paper version to complete the diary.
Environmental data will be obtained from the Met Office and will include physical, chemical and biological data on the lat-long co-ordinate of each participants home address during their study involvement.
Qualitative interviews will be conducted for a sub-sample of both acute and stable participants during their follow-up appointment. Participants will be asked about their COPD management, coping, and experiences of exacerbations. They will also be asked about their experiences of the study, the study technology and symptom diary, providing valuable feedback on how they could be improved.
Participants are free to withdraw at any time without providing a reason and with no change to their usual care.
