Appointed research nurses of DPH and HCA are asked to distribute research information pamphlets to all patients and family caregivers eligible for the study, based on their clinical assessments of patients using the Karnofsky Performance Status Scale; patients who received a score of 20 or below are considered too ill and ineligible to participate. At least one week is given for full consideration to participate in the study, after which, the research nurses contact each eligible family to seek their verbal consent for study participation. Once verbal consent is obtained, a simple information sheet containing the names and contact details of the patient-family dyad are forwarded to a member of the research team. The responsible researcher then contacts the patient-family dyad via telephone to organize a convenient time for the first baseline assessment meeting.
