The BOOST Paediatric Advance Care Planning Intervention for Adolescents with Cancer and Their Parents: Development, Acceptability and Feasibility

Abstract Background Although advance care planning (ACP) has been widely recommended to support patient and family engagement in understanding the patient’s values, preferences and goals of care, there are only a few models in paediatric oncology that capture ACP as a process of behaviour change. We aimed to develop and test the acceptability and feasibility of BOOST pACP (Benefits of Obtaining Ownership Systematically Together in paediatric Advance Care Planning) – an intervention to improve ACP in adolescents with cancer, their parents and paediatric oncologists. Methods Several methods informed the intervention development process: 1) Problem identification: interviews with 11 healthcare professionals working in paediatric oncology; 2) Identification of evidence: literature review of existing pACP tools and barriers and facilitators in performing pACP; 3) Logic model and 4) Intervention design: collaborative expert meetings with researchers and professionals in pACP; 5a) Acceptability test of the materials: interviews with 9 healthcare professionals, 4 adolescents and young adults with cancer and 6 parents; 5b) Feasibility test of core intervention components with 3 families, including interviews about their experiences. Results The BOOST pACP intervention was iteratively developed and adapted, based on feedback from families, healthcare professionals, and pACP experts (e.g., components were changed, deleted, and added; formulation of themes and associated questions were amended to enhance acceptability). The core components of the BOOST pACP intervention include: 4 ACP conversation sessions with the adolescent and/or parent(s) provided by a trained facilitator, structured by interactive conversation cards covering different ACP themes, followed by a transfer of information from the intervention facilitator to the paediatric oncologist. Core intervention components were deemed feasible by all participating families. Conclusion The BOOST pACP intervention was developed by close involvement of both adolescent patients and their parents, healthcare professionals and pACP experts. The final intervention and supporting materials are considered appropriate and feasible. Its effectiveness in improving parent-adolescent communication on ACP themes is currently being tested in a multi-centre randomised controlled trial. Researchers aiming to develop a complex psychosocial intervention for a vulnerable target group could use the step-by-step approach described in this paper.

Abstract Background Research has highlighted the need for evidence-based interventions to improve paediatric advance care planning (pACP) in adolescents with cancer. Although adolescents express the desire and ability to share their values, beliefs and preferences for treatment, there is a lack of structured multicomponent interventions to improve parent-adolescent communication on different ACP themes including those not limited to end-of-life care. The aim of this study is to evaluate the effectiveness and implementation, context and mechanisms of impact of a novel ACP program in paediatric oncology. Methods We will conduct a multi-centre parallel-group randomised controlled superiority trial with embedded mixed-methods process evaluation in Flanders, Belgium. Adolescents aged 10–18 who have cancer, and their parent(s) will be recruited via all four university hospitals in Flanders, Belgium, and support groups. Families will be randomised to receive care as usual or the multicomponent BOOST pACP program, consisting of three conversation sessions between an external facilitator and the adolescent and parent(s). The primary endpoint is improved parent-adolescent communication from the perspective of the adolescent. Secondary endpoints are adolescents’ and parents’ attitudes, self-efficacy, intention and behaviour regarding talking about ACP themes with each other, parents’ perspective of shared decision making in the last clinical encounter, and the paediatric oncologist’s intention and behaviour regarding talking about ACP themes with the family. Measurements will be performed at baseline, at 3 months and at 7 months using structured self-reported questionnaires. We will perform a process evaluation in the intervention group, with measurement throughout and post-intervention, using structured diaries filled out by the facilitators, interviews with facilitators, interviews with involved paediatric oncology teams, and audio-recordings of the BOOST pACP conversations. Discussion The BOOST pACP program has been developed to stimulate conversations on ACP themes between parent(s) and the adolescents, simultaneously lowering the threshold to discuss similar themes with healthcare professionals, initiating a process of normalization and integration of ACP in standard care. This combined outcome and process evaluation aims to contribute to building the necessary evidence to improve ACP in paediatric oncology. Trial registration The study is registered at ISRCTN, ISRCTN33228289. Registration date: January 22, 2021.
