Plain English Summary

Background and study aims
In the adult population, advance care planning (ACP) has shown to improve communication around care planning. However, ACP tools or interventions for child and adolescent cancer patients are scarce and evidence is lacking. There is evidence that adolescent patients have the desire and ability to share their values, beliefs, and preferences for treatment at the end of life. Especially communication about topics such as “what to do if the adolescent should get significantly worse” remains difficult, leaving room for improvement.

Aiming to improve parent-adolescent communication about ACP topics, the study team has developed an intervention for adolescents with cancer and their parent(s). This study will assess the effectiveness of a pediatric ACP intervention (BOOST) for adolescents with cancer and their parent(s) in Belgium. In addition, there will be a process evaluation to evaluate the implementation, mechanisms of impact, and context of the intervention.

Who can participate?
Adolescents aged 10 -18 with any type of cancer in treatment at the pediatric oncology ward, and their parent(s).

What does the study involve?
The intervention group will receive the BOOST pACP intervention. The control group will receive care as usual.

The goal of the BOOST pACP intervention is to improve parent-adolescent communication on advance care planning topics. The BOOST pACP intervention involves three conversation sessions between a trained facilitator (external to the medical team) and an adolescent with cancer andtheir parent(s). Before the conversation sessions take place, the family receives preparation booklets. During the first conversation session, the facilitator will introduce the content of the upcoming conversation sessions to the adolescent and parent(s), by showing a short video and discussing two topics with conversation cards. The second conversation session takes place with the adolescent and parent(s) separately and is structured by conversation cards. Examples of topics discussed are “worries and fears” and “expectations for the future”. In the third conversation session, the adolescent and parent(s) will fill out a summary sheet together. If they give permission, the facilitator will share the summary sheet with their pediatric oncologist.

Adolescents and parents will fill out questionnaires on three occasions: before the study begins; after they have received the intervention (approximately 3 months after the study begins); and again at approximately 7 months after the study begins. The questionnaires will evaluate attitude, self-efficacy, intention, and communication with each other regarding ACP topics (among other determinants). The pediatric oncologist questionnaires evaluate the ACP topics they have talked about to the family and the ACP topics they are planning to talk about to the family in the near future.

A process evaluation will be conducted to evaluate how the intervention was implemented and to assess the experiences of different groups. The process evaluation entails monitoring during the data collection period and interviews with adolescents and parents after the intervention and with facilitators and healthcare professionals after the data collection period.

What are the possible benefits and risks of participating?
This study can deliver valuable evidence about the effects of ACP for adolescent cancer patients. The aim is to facilitate parent-child communication about ACP topics, in a way that adolescents feel empowered to engage more in their care plan. Talking about care preferences and open communication within families and with the medical team could improve a sense of control and autonomy.

It is possible participants will experience negative feelings, due to reflecting on potentially sensitive topics more than usual. However, these risks are minimal, taking into consideration that adolescents and parents are able to decide what topics they would like to discuss in the sessions. The study team will also monitor anxiety in adolescents and parents to allow a timely response to adverse events. The trained facilitator will give the contact information of the psychologist on the ward at the start of the conversation sessions and will emphasize they can always contact them when needed.

Where is the study run from?
Vrije Universiteit Brussels (VUB) and Ghent University (Belgium).

When is the study starting and how long is it expected to run for?
September 2018 to October 2023

Who is funding the study?
The Research Foundation- Flanders (Fonds Wetenschappelijk Onderzoek) and the Child Cancer Fund (Kinderkankerfonds) (Belgium)

ConditionImproving communication on advance care planning (ACP) topics between adolescents with cancer and their parents
InterventionCurrent intervention as of 04/05/2021:
The intervention group will receive the BOOST pACP intervention (Benefits of Obtaining Ownership Systematically Together), in addition to standard care. The control group will receive care as usual.

Two routes will be used to recruit patients:
1. Pediatric oncologists (together with psychologists) at each of the four participating wards will select adolescents based on the inclusion criteria first. Subsequently, they will review whether their parent(s) adhere to the inclusion criteria also.
2. Through patient organizations and other non-profit organizations. Organizations will be asked to post an open call in their newsletters, on their website and on other social media platforms (eg. Facebook, LinkedIn and/or Twitter) or share this in other ways that are common communication channels when interacting with their members and network. The research team has developed a flyer and social media image for organizations to share. Interested families can contact our data collectors.

The intervention group will be compared in terms of parent-adolescent communication to a usual care control group. Randomization will be performed per a computerized random number generator with a 1:1 allocation ratio to either the intervention arm or the standard care arm (control group) using simple randomization. Randomization will be stratified by age (two groups: 10-14 years versus 15-18 years).

The intervention consists of the following 10 components:
1. Training of facilitators that will lead the conversation sessions and coaching on the job every 3 months
2. Preparation booklets for the parent(s) and the adolescent
3. A video with experts by experience talking about the impact of the intervention (shown during the first conversation session)
4. Conversation session 1 involves an introductory session with parent(s) and adolescent together. Two broad topics (identity; experience of disease and treatment) are discussed with conversation cards.
5. Conversation session 2a, only with the adolescent, involves a conversation with the adolescent alone. Six ACP topics are discussed with conversation cards: talking to others; hope and comfort; worries and fear; care preferences; expectations for the future; and about dying. Adolescents are asked to divide the topics into two categories: “I would like to discuss this topic with my parent(s)” and “at the moment I do not feel the need to discuss this topic with my parent(s)”.
6. Conversation session 2b, only with the parent(s), involves a conversation with the parent(s) alone. Seven ACP topics are discussed with conversation cards: talking to your child; parenthood; hope and comfort; worries and fear; care and treatment; expectations of the future; and about dying.
7. Conversation session 3 a conversation with parent(s) and adolescent together. They are given the opportunity to talk about certain ACP topics if they wish to.
8. The adolescent with parent(s) fill in a summary sheet together during the third conversation session. They can fill out whether they agree that this summary sheet is shared with their oncologist.
9. A transfer of information from the intervention facilitator to a treating pediatric oncologist/medical team, if families give permission
10. Conversation cards that can be used as a game of quartet at home. Families will receive conversation cards at the end of conversation session 3.

The conversation sessions are guided by a trained facilitator that has a background and experience as a psychologist, external to the treating medical team.
