Cognitively impaired and cognitively intact older adults seemingly differ regarding engagement in aspects of advance care plans (ACPs). Through informant reports in the Canadian Study on Health and Aging, we examined differences between deceased cognitively impaired and intact older adults in components of ACPs: (1) discussions/arrangements for end-of-life care; (2) creation of legal documents; and in ACP outcomes, (3) location of death; and (4) dying in accordance with wishes. Cognitively impaired older adults were more likely to have made arrangements for a substitute decision-maker (OR = 1.90) and to have created legal documents (OR = 2.64 for health care preferences, OR = 2.00 for naming a decision-maker). They were less likely to have discussed preferences for end-of-life care (OR = 0.62). These findings suggest that ACPs differ for cognitively impaired persons, indicating a need for further investigation. This is a step towards understanding this complex process in a particularly vulnerable population.
