Advance care planning at life milestones.

Much progress has been made in advance care planning (ACP), especially related to end of life and palliative care. These advances have moved thinking about ACP from a checklist approach to an upstream recognition that ACP is an iterative process that should begin early in adulthood and be revisited with each milestone or life-changing event. It is recognized that there are many stages and milestones in adult life that contribute to changing loci of responsibility and life goals.
