The seven elements of informed consent (as defined by Beauchamp and Childress) include threshold elements (competence and voluntariness), information elements (disclosure, recommendation, and understanding) and consent elements (decision and authorization). Some philosophers such as Harry Frankfurt consider Beauchamp and Childress criteria insufficient. They claim that an action can only be considered autonomous if it involves the exercise of the capacity to form higher-order values about desires when acting intentionally. What this means is that patients may understand their situation and choices but would not be autonomous unless the patient is able to form value judgements about their reasons for choosing treatment options they would not be acting autonomously.
