Decision making capacity fatigues after repeated decisions similar to skeletal muscle. The
result is decision fatigue, in which subsequent decisions are altered toward the status quo.
Surrogates are at risk for decision fatigue yet it has not been studied. We propose a
randomized study in the outpatient setting in surrogates and patients at high risk for
needing to make complex decisions, in an effort to determine the impact of decision fatigue
on surrogate self-control and subsequent choices.
