- Patients who are thought to have entered the terminal stages of their illness will be excluded. This will be judged at recruitment by the screening clinician from the patient's general practice. In the case that a recruited patient has become too ill to participate in the research or has died before participation, and a linked caregiver has expressed interest in the study, the caregiver will be contacted, offered sympathies, and will be given the opportunity to withdraw from the study or continue as planned. All conversations about the study will be conducted in a supportive manner that recognises the sensitivity of the subject matter.
