The use of advance directives for autonomy in dementia care: A scoping meta-review and thematic synthesis.

Dementia may reduce individuals' capacity for autonomy and decision-making competence. Advance directives are subject to theoretical bioethical debate as tools to safeguard or extend autonomy in dementia. However, the extent and manner in which advance directives are actually used for these purposes in practice remain less examined. We aimed to examine how advance directives are used as tools for individual autonomy in dementia care. We systematically searched six databases and performed a thematic analysis and synthesis of included reviews based on an original model of six autonomy-relevant dimensions of advance directives. A total of 18 reviews met the inclusion criteria. We identified 12 themes across six dimensions. We found a lack of knowledge integration on the actual use of advance directives for autonomy in dementia care. Evidence suggests significant variation in the autonomy-relevant dimensions of advance directives, with a tendency towards an inconsistent or low level of implementation as a tool for autonomy. Further reviews and primary studies on all aspects of the use of advance directives for autonomy in dementia care would contribute significantly to dementia research and practice.
