Informed consent Informed consent is a process through which the healthcare professional informs the patient about the treatment he or she will receive, as well as the risks, benefits and alternatives. This information and understanding process finishes in the signing of the written informed consent form, a document in which the patient authorises the performance of the medical service. This signature must be made consciously and voluntarily by the patient, who can accept it or reject it. The objective is that the patient can make decisions regarding his or her health according to his or her own free will. In addition, it is verified that the patient has received and understood the information provided by the professional responsible for his or her treatment. The current state regulation of information and consent is included in in Law 41/2002, of November 14th, the basic regulator of patient autonomy and of rights and obligations in matters of clinical information and documentation. As its name indicates, it shows respect for fundamental rights such as autonomy and self-determination, where the patient, after receiving adequate information, will make his or her own free. According to the current legislation (Law 41/2002) any action in the field of a patient's health requires the free and voluntary consent of the affected, in addition, in the case of the example provided, as it is a dental extraction, which can be considered as an invasive procedure since it involves certain risks, must be collected in writing. According to my personal experience, since I have recently had to undergo two endodontic procedures, I have previously been given information about what the technique consists of, as well as its possible consequences and complications. In addition to this, on the day I had them performed, I was previously given the informed consent document, collecting all the fundamental information that had already been given to me beforehand so that it was recorded that I had been adequately informed on the basis of my needs and therefore authorised to finally carry out the procedure. The patient's consent has to be given before the intended action, once the appropriate information has been provided. Whenever possible, information should be provided sufficiently in advance to allow the patient to reflect and ask for any clarification he or she considers necessary for a decision to be taken.
