Abstract

Advance directives allow people to accept or decline medical interventions and to appoint surrogate decision makers if they become incapacitated. Living wills are written in ambiguous terms and require interpretation by clinical providers. Living wills cannot cover all conceivable end-of-life decisions. There is too much variability in clinical decision making to make an all-encompassing living will possible. While there are many limitations of advance directives, this article reviews some of the most troublesome ethical dilemmas with regard to advance directives.
