Experiences and perspectives on chimeric antigen receptor (CAR) T-cell therapy among recipients, carers and referrers (RE-TELL): a qualitative study to inform CAR T-cell service design

Abstract

ObjectivesRE-TELL is a qualitative study, which aims to understand patient, support person, clinician and coordinator experiences and perspectives of chimeric antigen receptor (CAR) T-cell therapy, to inform design of a clinical CAR T-cell service in Aotearoa New Zealand.DesignSemistructured qualitative interviews focused on domains of: experience through treatment, elements that work well and those that could be improved on. Interviews used thematic analysis to identify key themes. A workshop was held to obtain participants’ reflections on interim analysis and proposed improvements.ParticipantsNew Zealanders with experience of CAR T-cell therapy, including recipients, support persons, clinicians and coordinators.ResultsWe interviewed 19 participants comprising 5 CAR T-cell recipients, 3 support persons, 6 clinicians and 5 coordinators. Four participants identified as Māori. Thematic analysis identified three global themes. The first, ‘sociocultural factors impact CAR T access’, identified potential sources of inequity including geographic, financial and informed consent barriers. The second, ‘varying emotions, roles and enablers’, identified an easier treatment experience compared with alternatives; an underwhelming cell administration process; frustration with inpatient monitoring; burden on support persons and importance of ‘bridge’ organisations such as charities and patient support groups. Lastly, ‘golden opportunities: reimagining CAR T service delivery’, suggested: improved geographical access to CAR T-cell therapy, while retaining consolidated clinician experience; a ‘dashboard’ with information on CAR T-cell treatment, time frames and manufacture; a health navigator to co-ordinate non-medical aspects of treatment and signpost care; embedding of indigenous data sovereignty and ownership of cells; a cell infusion ceremony, incorporating family involvement and Māori cultural elements and outpatient administration and monitoring where possible.ConclusionThis study documented the current experience of New Zealanders receiving CAR T-cell therapy and identified opportunities for future service development. These insights are relevant to service design within Aotearoa New Zealand, and other countries developing equitable CAR T-cell services.
