Many ethical dilemmas in clinical care involve a conflict between clinical indications and patient preferences (5). The patient's preferences are crosswise with what is deemed medically beneficial, creating a conflict between duties of beneficence (promoting patient welfare) and respecting patient autonomy (respecting patient wishes). To work through such dilemmas, one must first explore fully and thoughtfully the patient's preferences as well as the clinical indications. Why does the patient refuse treatment? Does the patient have the cognitive and emotional capacity to make this decision at this time? How urgent is the clinical situation, and is time available for discussion, collaboration, and perhaps compromise? Clinical standards for medical decision-making capacity include a genuine appreciation of the medical situation, the nature of the recommended care, and potential alternative courses for care along with the benefits, risks, and consequences of each alternative. In addition, the individual should have the ability to communicate a choice and to understand the information relevant to the medical situation. Decisions need to be arrived at through reasoning and must be consistent with the patient's values and goals. In this case, the patient appears incapable of recognizing the facts of his own medical situation. As a result, he cannot appreciate the potential consequences of his medical situation (1, 5, 6).
