Informed consent in theory and practice

The theoretical, legal, and medical doctrines of informed consent are analyzed. The elements of informed consent include disclosure of information, competency, understanding, voluntariness, and decision-making. The doctrine is ground in deference to individual autonomy and recognition that the exercise of self-determination in matters of health is a liberty interest honored by our history and traditions. The exceptions to informed consent including emergency, incompetency, therapeutic privilege, and waiver are especially important in critically ill patients and reflect a balancing of autonomy values and society's interest in the promotion of health. Legal decisions inevitably are based on atypical physician-patient encounters and focus on a particular problem or procedure rather than on overall medical care. In addition, they often reflect an artificial view of the doctor-patient relationship. Medical decision-making is a complex, evolving pursuit of a diagnosis and proper treatment regimen. Moreover, patients are not always interested in the role assigned to them by law. A reconceptualization of informed consent doctrines utilizing sliding scale standards based on variables pertinent to each individual patient is suggested.
