If a participant decides they would like to take part and contacts the respiratory research team or have been contacted by the team, an initial appointment will be arranged. This will take part at the participants home, GP surgery or Queen Alexandra Hospital depending on the patients choice. After obtaining consent, suitability for inclusion onto pulmonary rehabilitation will be assessed. A full medical history (including confirmation of diagnosis, COPD severity, smoking history, medications and current activity) along with blood pressure will be taken to assess for any exclusion criteria. The timed "Up and Go" Test will also be performed to assess safety of mobility and exercising. This is to ensure it is safe for the participant to exercise independently. If a participant does not meet the inclusion criteria, they will be referred back to their GP with the reason they were not suitable for PR. It is explained to the participant that they can withdraw from the study at any point and that this will not affect their care. If a participant decides they do not wish to be included onto the study they will be referred to the conventional NHS PR programme. If a participant is suitable for PR and is willing to participate, further screening is undertaken. This can take place immediately if this initial appointment is carried out at QAH, or a further appointment will be arranged at QAH will be arranged.
