Informed Consent Is the Essence of Capacity Assessment.

Informed consent is the single most important concept for understanding decision-making capacity. There is a steady pull in the clinical world to transform capacity into a technical concept that can be tested objectively, usually by calling for a psychiatric consult. This is a classic example of medicalization. In this article I argue that is a mistake, not just unnecessary but wrong, and explain how to normalize capacity assessment. Returning the locus of capacity assessment to the attending, the primary care doctor, and even to ethics consultation in today's environment will require a substantial effort to undo a strong but illusory impression of capacity assessment. Hospital attorneys as well as clinical ethicists with a sophisticated understanding of health law can be in the vanguard of this reorientation.
