Best Practices For Designing Discrete Choice Experiments And The Use For Older Adults With Cognitive Impairment

Objective: the aim of this scoping review is to 1) identify guidelines, frameworks, issues, and recommendations regarding the development of a discrete choice experiment (DCE), 2) look at potential design considerations regarding the development of a DCE for older adults with dementia, and 3) summarize knowledge about the current inclusion of and experiences with older adults with cognitive impairment in DCE studies. Methods: Two literature searches divided into two topics were performed in PubMed, CINAHL, and PsycINFO. Results: Topic 1 found 19 articles regarding frameworks, guidelines and design considerations for DCEs in healthcare. Topic 2 found eight articles regarding the effect of cognitive impairment on DCE results and/or discussing the inclusion of cognitive impaired older adults in these DCE studies. Conclusion: There is minimal literature available regarding the effect of cognitive impairment on DCE results. In future studies we will explore if DCEs can be used to involve older adults with dementia in decisions regarding transitions in care.
