The experimental arm of the Colour COPD Trial will receive a 5 point sputum colour chart, adapted from Bronkotest® a self-management plan and rescue pack containing 5 days of antibiotic and steroid treatment.
Participants in both the experimental arm and control arm will receive a screening appointment and 12 month follow up appointment which will be similar to the usual annual COPD review, thus align well to usual care. These appointments will take place either face-to-face at the GP practice, over a video link or via the telephone. Participants will also receive telephone calls at 2 weeks, and then at 3,6 and 9 months after enrolment, these follow up telephone calls which will be carried out by the research team at the University of Birmingham.
