Advance Care Planning can be used to engage people with dementia in decision-making about future care. The current studyaims to advance the state of knowledge about Advance Care Planning interventions aimed at older people with early-stagedementia and to describe the effects of various interventions as well as the feedback on the interventions from this patientgroup and their family caregivers. The study is reported in accordance with PRISMA for scoping reviews. The search for studiesand reports included electronic databases, websites, books, and reference lists. Data from the selected studies, includingpublication year, title, purpose, study population, intervention, methods, and results, were extracted. Six full-text articleswere identified as suitable for inclusion. The six interventions had differing approaches. A supportive structure was helpfulfor both people with dementia and family caregivers. The feeling of being listened to and engaged in the care planning seems tobe of most importance, not the intervention design itself.
