Informed consent is an official document that legally serves as evidence that the patient has agreed to the treatment or surgical procedure, after having a full understanding about the procedure, its indications, benefits, risks and alternatives. The elements that constitute the validity of an informed consent include voluntarism, capacity, disclosure, understanding, and decision. Understanding entails that the patient has full knowledge of the procedure and its relevance to the condition. Disclosure is the counterpart of the physician in providing the patient the needed information of the procedure such as nature, purpose, risks, benefits, and feasible alternatives. Capacity refers to the legal authority of the patient to make decisions concerning own healthcare. Decision is when the patient signifies and authorizes the physician and hospital to perform the procedure.
