Patient advisors

Patient and public involvement (PPI) refers to an active partnership between patients and/or members of the public and researchers. Researchers and clinicians may not have first-hand experience of the illness, disease or health condition that they wish to research. PPI groups can therefore provide researchers with insights into what it is like to live with a particular disease, illness or health condition helping to make health research more relevant to the needs of patients, carers and service users.

Our group of patient advisors all have COPD and first-hand experience of Pulmonary Rehabilitation.
