Background: In Canada, more than 60% of persons living with dementia reside in their own homes, and over 25% rely heavilyon their care partners (ie, family members or friends) for assistance with daily activities such as personal hygiene, eating, andwalking. Assistive technology (AT) is a key dementia management strategy, helping to maintain health and social support inhome and community settings. AT comprises assistive products and services required for safe and effective use. Persons livingwith dementia and their care partners often require multiple types of AT to maintain their needs, dignity, and autonomy. AT fordementia management is rapidly developing with abundant scientific literature, which can present a challenge to efficientlynavigate and extract insightsfor policy and personal decision-making. Objective: This scoping review aims to synthesize review-level evidence from published scientific literature on AT to supportdementia management for persons living with dementia and their care partners in their homes and communities. Research gapsin knowledge and areas for further investigation into the use and access of AT will be identified. This review will provide anoverview of AT types and characteristics and chart the outcomes and conclusions in review-level evidence. Methods: This review will follow the Joanna Briggs Institute's framework for conducting scoping reviews and the PRISMA-ScR(Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. In total, 6electronic databases will be searched. Articles will be screened according to the Population-Concept-Context (PCC) frameworkfor eligible studies. Population includes persons living with dementia, their care partners, and health care professionals (eg,therapists or others who recommend AT). Concept includes AT and self-help devices of many types. Context includes homesand communities. A data charting template will guide data extraction, charting, and summarization. A descriptive numerical summary and an overview of the findings will be presented. Data, such as (1) article information (eg, author and year), (2) articlecharacteristics (eg, review type), (3) AT types and characteristics, (4) setting and population characteristics, and (5) key reviewoutcomes and conclusions, will be extracted. Results: A total of 10,978 unique citations were identified across the 6 electronic databases. This review is in the full-textscreening stage, which is expected to be completed by October 2024. Conclusions: This review will provide a comprehensive understanding and documentation of the published scientific literatureon AT to support dementia management. Findings from this review are expected to provide evidence-based insights on thecomplexities of AT types, uses, availability, and access. The author group's diverse national and international perspectives maycontribute to knowledge exchange and influence standards to improve the daily function, safety, and well-being of persons livingwith dementia.
