In the preceding chapter we spoke of the requirement for informed consent in absolute terms, as something that was an invariable component of medical decision making. Over the years, courts have come to recognize that there are a number of situations in which physicians are permitted to render treatment without patients’ informed consent. Even under the earlier simple consent requirement, consent to treatment was not required in all situations. There are different kinds of situations in which requiring disclosure and obtaining consent could be detrimental to the patient, such as in an emergency or when the disclosure itself would harm the patient, and therefore in these situations informed consent is not required. Patients may also waive, or give up, the right to be informed and/or to consent. Here the concern is not with promoting health values but with promoting autonomy. Informed consent may also be dispensed with in a fourth set of cases, those of legally required treatment, in which the harm from requiring informed consent is not necessarily to the patient (or the patient alone) but to other important societal interests (e.g., civil commitment of the dangerous mentally ill—see Chapter 11—or forced treatment of patients with infectious disease). In addition, informed consent requirements are modified when a patient is incompetent (see Chapter 5). Each of these exceptions contains the potential for undermining the values sought to be implemented by the informed consent doctrine: self-determination and informed decision making. Exceptions that are too broadly defined and applied are a threat to these values. On the other hand, these exceptions are an important vehicle for the interjection into the decisionmaking process of another set of values, society’s interest in promoting the health of individuals. When judiciously defined and applied, the exceptions accord health-related values their due. However, the exceptions can be, and sometimes have been, defined so broadly as to dilute, if not dissolve, the fundamental duties imposed by the doctrine and to undermine its essential purpose of assuring patient participation in medical decision making (1).
