Background: Broad consensus exists on the relevance of advance care planning in dementia. Although people with young-onset dementia and their family are hypothesized to have distinct needs and preferences in this area, they are hardly ever included in studies. Aim: We aim to explore the experiences with and views on advance care planning of people with young-onset dementia and their family caregivers. Design: A qualitative study was conducted, analyzing semi-structured interviews through the method of constant comparative analysis. Setting/participants: We included 10 people with young-onset dementia and 10 of their family caregivers in Flanders. Results: Participants lacked awareness about the concept of advance care planning, especially as a communication process. They had not or barely engaged in planning future care yet pointed out possible benefits of doing so. Initially, people with young-onset dementia and their caregivers directly associated advance care planning with planning for the actual end of life. When discussing advance care planning as a communication process, they paid ample attention to non-medical aspects and did not distinguish between medical, mental, and social health. Rather, respondents thought in the overarching framework of what is important to them now and in the future. Conclusions: Engagement in advance care planning might be hindered if it is too medicalized and exclusively patient-centered. To accommodate advance care planning to people with young-onset dementia’s and their caregivers’ needs, it should be presented and implemented as a holistic, flexible, and relational communication process. Policy and practice recommendations are provided on how to do so.

Background: The significance of advance care planning in dementia is widely acknowledged. Despite the suggestion that younger people with dementia and their family might have distinct needs and preferences in this area, studies on advance care planning in young-onset dementia are absent. Aim: We aim to explore (1) whether family caregivers had already engaged in advance care planning with patients and/ or professionals and the accompanying reasons and (2) family caregivers’ preferences for how to ideally engage in the process with patients, family and professionals. Design: A qualitative study was conducted: we analysed semi-structured interviews ( n = 15) through the method of constant comparative analysis. Setting/participants: We included Flemish family caregivers of persons with young-onset dementia. Results: Plans for the future typically concerned non-medical affairs. Participants’ limited engagement in advance care planning was clarified through several reasons: not considering it useful, hindering patient behaviour, adopting a day-to-day attitude, caregivers emotionally protecting themselves and uncertainty about patients’ cognitive competence. However, endorsement for advance care planning showed from respondents’ preferences that it should be initiated timely, by a third party, and emphasize patients’ remaining capacities. Finally, the need for information and high-quality care emerged. Conclusion: A gap of knowledge, of information and in care intertwiningly hinder advance care planning. In young-onset dementia, engaging in advance care planning is not an option equally accessible as not doing so. Policy makers, institutions and professionals could reflect on their responsibility in providing these patients and caregivers an actual choice to engage in advance care planning or not.
