Surrogate decision makers (SDMs) are challenged by difficult decisions at the end of life. This becomes more complex in young adult patients when parents are frequently the SDMs. This age group (18 to 39 years old) commonly lacks advanced directives to provide guidance which results in increased moral distress during end of life decisions. Multiple factors help guide medical decision making throughout a patient's disease course and at the end of life. These include personal patient factors and SDM factors.
