Advance Care Planning in the Context of Dementia: Defining Concordance

Background and Objectives Individuals with dementia may require a surrogate decision maker as their disease progresses. To prepare for this potential role, dementia care partners need to develop a thorough understanding of their care recipient's end-of-life values and preferences, or care dyad advance care planning (ACP) concordance. As part of our pilot study implementing the LEAD intervention with dementia care dyads, we conducted a multimethod investigation to define care dyad ACP concordance.Research Design and Methods We conducted a scoping review of peer-reviewed studies published after 1991 in English focusing on care dyad ACP concordance in dementia care and included 34 articles. Concurrently, we used descriptive qualitative analysis to analyze 7 dyadic ACP conversations from a pilot study about dyadic dementia ACP.Results The scoping review demonstrated (a) no definition of care dyad ACP concordance was reported; (b) surrogate accuracy in end-of-life decisions varies widely; and (c) best practices for ACP in dementia may aid in achieving ACP concordance, but do not prioritize it as an outcome. Qualitative analysis identified 7 elements for achieving concordance: Respect/Regard; use of Clarifying Processes; Conveying Health Care Scenarios; Affirmation of Understanding; Recognizing Uncertainty; Expression of Positive Emotions; and Trust.Discussion and Implications Care dyad ACP concordance occurs when care recipients and care partners both understand a care recipient's end-of-life values, understand the end-of-life preferences informed by those values, and the care partner expresses a willingness to accomplish the care recipient's wishes to the best of their ability. ACP concordance can be further operationalized for research and clinical care.
