Advanced care planning (ACP) is a process of thinking about, talking about, and sometimes documenting preferences and wishes for future care. ACP provides an avenue to include persons with dementia in care planning when capacities for expressed preferences are more consistently present. ACP also offers families direction on future care decision making which can alleviate burden. However, knowledge gaps exist regarding when to engage persons with dementia and care partners in ACP discussions and what areas of future care to focus on. This presentation will provide an overview of a series of studies that together examined the types of ACP conversations considered most pertinent for persons with dementia and their families, the challenges and opportunities of using ACP workbooks and other materials to support ACP processes and the current state of comfort and capacity to address ACP with persons with dementia.
