ContextGiven recent Medicare rules reimbursing clinicians for engaging in advance care planning, there is heightened need to understand factors associated with the timing of advance directive (AD) completion before death and how the timing impacts care decisions.ObjectiveThe purpose of this study was to investigate patterns in timing of AD completion and the relationship between timing and documented care preferences. We hypothesize that ADs completed late in the course of illness or very early in the disease trajectory will reflect higher preferences for aggressive care.MethodsWe conducted a retrospective study using logistic regressions to analyze data from the Health and Retirement Study, a nationally representative longitudinal survey of older adults.ResultsThe analytic sample included exit interviews conducted from 2000 to 2012 among 2904 proxy reporters of deceased participants who had an AD. Nearly three-quarters (71%) of ADs were completed a year or more before death. Being younger or a racial/ethnic minority, and having lower education, a diagnosis of cancer or lung disease, and an expected death were associated with completing an AD within the three months before death, while having the lowest quartile of assets and memory problems were inversely associated with AD completion. Minorities, those with lower education, expected death, and timing of AD completion were associated with electing aggressive care.ConclusionEarly documentation of care wishes may not be associated with an increased likelihood of electing aggressive care; however, ADs completed in the last months of life have higher rates of election of aggressive care.Copyright © 2016 American Academy of Hospice and Palliative Medicine.
