Does it Matter Who Decides? Outcomes of Surrogate Decision-Making for Community-Dwelling, Cognitively Impaired Older Adults Near the End of Life.

Abstract Context Cognitively impaired older adults frequently need surrogate decision-making near the end-of-life. It is unknown whether differences in the surrogate's relationship to the decedent are associated with different end-of-life treatment choices. Objectives To describe differences in end-of-life care for community dwelling, cognitively impaired older adults when children and spouses are involved in decision-making. Methods Retrospective observational study. Results Among 742 community-dwelling adults with cognitive impairment (mild cognitive impairment or dementia) prior to death, children participated in end-of-life decisions for 615 patients (83%) and spouses participated in decisions for 258 patients (35%), with both children and spouses participating for 131 patients (18%). When controlling for demographic characteristics, decedents with only a spouse decision-maker were less likely to undergo a life-sustaining treatment than decedents with only children decision-makers (P Conclusion Decedents with cognitive impairment or dementia were less likely to receive life-sustaining treatments when spouses versus children were involved with end-of-life treatment decisions but were no less likely to experience other measures of potentially burdensome end-of-life care.
