If you take part in the trial then you will be required to visit your local trial team on a number of occasions during your 12 month trial period. There will be 6 visits in total and where possible these will be scheduled to coincide with your usual asthma outpatient appointments.
The initial visit, called the screening visit, will involve questionnaires, breathing tests, a blood test and allergy testing to determine whether you are suitable for the trial. At your second visit, called the randomisation visit, we will review the results of the tests from the screening visit and if you are eligible to take part, delivery and installation of a study device will be arranged.
You will receive a phone call after 1 month to check that everything is going ok and that there are no problems with the study device.
At 3, 6, 9 and 12 months after the device has been installed you will be seen by your local trial team and you will be asked to repeat the breathing tests and questionnaires.
