People with dementia and their care partners report a lack of support, treatment, and information, fragmented services, and a lack of inclusion in decisions about their care. Care planning may address these issues; however, there is scarce literature on the process or benefits of care planning for people with dementia. This review describes the literature on care planning for community-dwelling people with dementia and their care partners. A systematic scoping methodology was followed to identify the research questions, identify relevant documents, select relevant documents, chart the data, and collate, summarise, and report the results. 31 full-text documents published between 2010 and May 2020 were identified and reviewed. Seven were guidelines, seven were expert opinion pieces, 11 were intervention studies, and six were descriptive studies. The topics and process of care planning varied depending on the service context (e.g., memory clinic, home care, and primary care). Care planning was presented as a component of case management in 15 papers. Six of the 11 intervention studies reported positive outcomes, one showed no improvement, and one did not evaluate outcomes for people with dementia or their care partners. Of the six with positive outcomes, four evaluated care planning in the context of care management. There is limited evidence that care planning alone improves outcomes for people with dementia and their care partners. It is unclear whether it may have benefits when combined with care management.
