Decision-Making Capacity to Refuse Treatment at the End of Life: The Need for Recognizing Real-World Practices

End-of-life decision making is a troublesome ethical dilemma. These decisions should be made in trustful patient-doctor relationships. We aimed to propose a balanced approach when discussing this complex issue. We categorized the research into four approaches and suggest that a multidisciplinary approach may be appropriate. We also analyzed the pitfalls of the multidisciplinary approach. Our conclusion is two-fold. First, discussions in this field should be based on real-world practice. If this is not the case, the proposal may be armchair theory, which is not effective in a clinical setting. Second, interdisciplinary researchers should not stick to their position too firmly and should listen to others. Otherwise, proposals made will be paternalistic or philosophically biased. Therefore, when philosophical collaboration is applied to the topic of clinical bioethics, it is necessary to thoroughly examine different positions and carry out careful discussions with consideration for medical care settings. Researchers must also understand what is needed for a trustful patient-doctor relationship. By making such efforts, clinical bioethics will contribute to the wellbeing of patients.
