Planning for end-of-life care: findings from the Canadian Study of Health and Aging.

Steps involved in formalizing end-of-life care preferences and factors related to these steps are unclear in the literature. Using data from the third wave of the Canadian Study of Health and Aging (CSHA-3), we examined the relations between demographic and health predictors, on the one hand, and three outcomes, on the other (whether participants had thought about, discussed , or formalized their end-of-life preferences), and considered, as well, whether relations existed among the three outcomes. Canadian region of residence, female gender, and more years of education predicted having thought about preferences; region of residence, female gender, and lack of cognitive impairment predicted discussion of preferences; and region of residence and not being married predicted whether formal documents were in place. Ontario residents were most likely to have thought about, discussed, and formalized their preferences, whereas Atlantic residents were least likely to. Finally, having thought about preferences was associated with discussion, and having thought about and having discussed preferences were each associated with formalization of preferences. These findings are in keeping with the position that Advance Directives (AD) execution is a multi-stage process. A better understanding of this process may prove useful for the development of interventions to promote planning for end-of-life care.
