This document discusses capacity vs competence and provides guidance on assessing a patient's capacity to make medical decisions. It defines capacity as the ability to make an informed decision about a specific treatment, while competence is a legal term determined by a court. Capacity is situation-specific and the threshold for what constitutes capacity depends on the risks of a patient's choices - higher risk decisions require a higher level of understanding. It provides criteria for assessing decision-making capacity, including communicating a choice, understanding information, appreciating consequences, and reasoning about options. Clinicians should document whether a patient has capacity and the basis for that determination.
