Plain English Summary
Background and study aims
Chronic Obstructive Pulmonary Disease (COPD) is a severe lung condition that affects a person's ability to exercise and perform normal physical functions due to a combination of breathlessness, poor physical fitness and loss of muscle strength. Patients with COPD often experience flare ups known as exacerbations due to chest infections, which result in their symptoms getting worse, more loss of function, and may require hospital treatment. Recovery from such exacerbations is often slow, and some patients never fully return to their previous level of activity. This can lead to permanent disability and premature death. The purpose of this study is to find out whether it is possible to undertake a larger study of exercise training in patients who have been admitted to hospital with a flare up of their COPD. We aim to find out whether patients will be willing to participate and perform exercise both during their time in hospital and then immediately after they get home, to see if this will allow patients to recover more quickly and get back to their previous level of activity without needing to stay in hospital for a prolonged period. Both of these periods of exercise will be started much earlier than the rehabilitation classes that are currently widely available to COPD patients after they have been in hospital. This study will help us to understand if exercising earlier after hospital admission has any benefits over exercising later and will help us to decide if a large study looking more closely at this is required.
Who can participate?
Patients who have been admitted to hospital with a flare up of their COPD.
What does the study involve?
The study will look at two different sorts of exercise: a bedside bicycle-based activity that can be undertaken whilst the patient is sat at the edge of their bed in hospital, and a supervised exercise program to be undertaken during the first two weeks after they have been discharged. Both forms of exercise will be supervised by a physiotherapist. The study will look at whether participants will be prepared to take a walking test and a special movement watch that patients will wear at home. They will also be asked to complete several questionnaires that ask about their activities at home and how their breathing problems are affecting their quality of life. Whilst they are in hospital a measurement of their muscle size will be done to see whether the exercise helps stops the muscles from wasting away when they are unwell. We will assess whether or not exercising participants early after a hospital admission has any affect in preventing further chest infections or flare ups of COPD, or reduces the number of re-admissions to hospital occurring within 3 months of discharge.
What are the possible benefits and risks of participating?
Participants may benefit from being in the study as exercise has been shown to help with recovery following COPD flare ups, and it is recommended that this activity starts within a month of being in hospital. However, in this study the exercise will happen in hospital and straight after discharge, which is earlier than what currently happens. There is the possibility that doing the exercise earlier may not be beneficial, and could cause some problems such as more difficulty breathing and muscle tiredness, but the activity will be carried out with a trained physiotherapist who is aware of these risks and will be looking out for them.
Where is the study run from?
The study will be run in Sheffield Teaching Hospitals NHS Foundation Trust and Aintree University Hospital NHS Foundation Trust (in Liverpool), with patients recruited from the Northern General Hospital and from Aintree University Hospital (UK).
When is the study starting and how long is it expected to run for?
The study will run from January 2015 to December 2016.
