Who will take informed consent? 
RECRUITMENT
The research assistant for this trial (CF) will screen for potential study participants from a series of Hospital oncology and haematology outpatient clinics. Nursing colleagues working at these clinics will be assisting in the recruitment process. Once interested candidates meet the eligibility criteria, they will be provided with participant information leaflets, and informed written consent will be obtained by way of in-person clinic attendance. All potential participants will have the opportunity to withdraw at any time point during the study period.
