AbstractBackgroundDementia can negatively impact the well‐being and quality of life of patients and informal caregivers. Digital self‐management tools have the potential to support those living with dementia. The aim of this review was to identify digital tools used in dementia care, investigate how they support users, and highlight pertinent clinical and psychosocial outcomes.MethodSix databases were searched (i.e. CINAHL, EMBASE, MEDLINE, PsycINFO, Web of Science, and the Cochrane Review) using free text and equivalent database‐controlled vocabulary terms.ResultTwenty‐six articles were identified reporting 21 digital tools focused mainly on caregivers ‐ thus caregivers form the focus of this review. The digital tools promoted self‐management and support through five main functions: Supporting psychoeducation and self‐help; improving competency and ability; sustaining and promoting well‐being; encouraging behaviour change and providing motivation; and facilitating contact and communication with healthcare professionals and other users. There was mixed‐to‐limited evidence to support a positive influence of digital tools on mental health, burden, quality of life, and caregiver perceived ability.ConclusionDigital health technology has the potential to support caregivers, however areas such as mental health, burden, and quality of life may be resistant to some digital interventions. It is important to understand issues around accessibility, uptake, and continued use of digital tools and their potential to be integrated within dementia care pathways and routine clinical care.
