Aim
Long-term care considerations for persons with dementia are complex. Multi-criteria decision analysis (MCDA) methods are increasingly used to support healthcare decisions. The objective of this scoping review was to identify and analyze published MCDAs in which preferences for living and care concepts for persons with dementia are determined.
Subject and methods
A literature search was conducted in PubMed, EMBASE, Web of Science, and Google Scholar in October 2021. Searches were limited to peer-reviewed articles published up to October 14, 2021. The included publications aimed at eliciting care preferences for persons with dementia from patients, relatives, healthcare practitioners or the broader public by means of MCDA.
Results
Ten studies were included of whom seven were published in 2017 or afterwards. In nine studies, a discrete choice experiment (DCE) was conducted. The majority of studies surveyed the general population or caregivers of persons with dementia. Five studies assessed preferences for attributes of home care and two for long-term care facilities. Willingness to pay was addressed in eight studies. Choice task structure and experimental design varied widely. Despite different objectives, strong preferences for continuous care by the same person, organizational aspects, and caregiver expertise were found across studies.
Conclusion
This review shows that MCDA methods have successfully been applied to analyze preferences for living and care arrangements for persons with dementia. The majority of publications report on DCEs, and a variety of different study objectives and methodological approaches have been observed. Further research is needed to inform the design of innovative concepts which are a valuable alternative to existing care options.
