Supported decision-making with persons with dementia: a scoping review protocol in partnership with lived experts

Introduction The United Nations Convention on the Rights of Persons with Disabilities asserts that all persons with disabilities have the right to receive the support they require to participate in decisions that affect them. Yet, persons with dementia continue to be excluded from decisions on issues that matter to them. Our planned scoping review seeks to address this gap by documenting the current knowledge on supported decision-making for persons with dementia and informing the next steps for research and practice.Methods and analysis We will use Arksey and O'Malley's (2005) six-stage framework to guide our review of the English scientific literature (2005 onwards), searching the following databases: MEDLINE, PsycINFO, CINAHL, AgeLine and the Social Science Abstracts. Our review will focus on primary studies examining supported decision-making for persons with dementia, including the voices of those with dementia. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews, we will identify (1) domains of supported decision-making discussed in the empirical literature and (2) practices/factors that facilitate or inhibit supported decision-making. Consultations with persons with dementia and their care partners will provide insights into lived experiences, helping identify gaps between research literature and lived realities. The preliminary title and abstract search for eligible articles were conducted between August and October 2023 and updated in June 2024, yielding 56 eligible articles for review.Ethics and dissemination This scoping review will be conducted following the standards of the Tri-Council Policy Statement for Ethical Conduct for Research Involving Humans (1998 with 2000, 2002 and 2005 amendments). The procedures for eliciting feedback from persons with dementia and their care partners were approved by the Office of Research Ethics Board at McGill University (Reference # 23-08-048). Dissemination of review findings to persons with dementia and care partners will occur during ongoing community consultations. Visual aids and brief lay summaries will be used to facilitate input and dialogue. Dissemination to the broader practice and research communities will include workshops conducted in collaboration with study partners and presentations and publications in peer-reviewed forums.
