Many patients’ families feel unhappy when they are asked to sign a pre-operative interview, and some even equate it to signing a “life and death” letter. On the other hand, when there is a medical incident or a medical accident, both the doctor and the patient will take this document out and say something about it. In fact, this document can not and should not take such responsibility. The document “Pre-operative Talk” is in essence “Informed Consent of the Patient (for Medical Measures)”. As the name implies, the primary function of this document is to allow the patient to be informed, to read it, to have as clear and detailed an understanding as possible of his or her condition and the circumstances surrounding the treatment of the disease, and to make a decision on that basis as to whether or not to accept the medical treatment provided by the doctor. So, what are the most important things that the doctor should tell the patient in terms of “information”? First, of course, the patient must have a clear understanding of his or her condition. What is the disease, where it is located, what is its nature, how serious it is, and whether it is combined with other conditions that may affect treatment. Second, the patient must understand the need for surgical treatment. What is the purpose of surgical treatment and what benefits it can bring to the patient. Finally, of course, the risks of surgical treatment must be communicated. In a strict sense, any medical intervention carries with it foreseeable or unpredictable risks, which can sometimes be so great as to endanger the life or health of the patient. An informed consent form with these three components is a complete document. It is the third part, which emphasizes the risks and possible complications of the procedure, that gives the impression of a “life and death” agreement. In fact, it is for the benefit of the surgical treatment that the treatment is performed and that the patient receives the treatment, and only when the benefit far outweighs the risk does it make real sense. A document that overemphasizes the benefits may hide the bogeyman; a document that overemphasizes the risks may contain an abdication of responsibility. Therefore, a bad informed consent document may exacerbate the mistrust between doctor and patient, and may be the product of mutual distrust. And a warm, objective and humane informed consent can help build patients’ confidence, promote mutual trust between doctors and patients, and avoid unnecessary misunderstandings and medical disputes that are embarrassing for both doctors and patients. The “informed consent for medical treatment” should not be equated with the “medical liability division”. This document should not assume excessive responsibility. What should be done is to let the patient be informed as much as possible, that’s all. As for the determination of medical liability, that is another matter. It does not follow that if an accident or complication occurs that is listed in the informed consent form, the provider is no longer liable. If a medical practitioner fails to protect the interests of the patient, fails to take the necessary measures to avoid possible complications, or fails to make every effort to save the patient after a complication or accident has occurred, the medical practitioner’s liability is still inevitable. On the other hand, it is also important to recognize that the life process is so complex that there are always unexpected events in the development of disease, and our knowledge is still limited and we cannot always anticipate all possible problems. The table of medical accidents and complications only lists the most frequent and serious cases. If some accidents and complications occur that are not on this list, the medical provider cannot be held responsible for them. It is necessary to objectively analyze whether the medical party has done its due diligence in the process of medical treatment and has done its duty as a medical party. If the doctor has done his or her best, then he or she should be exempted from liability. I often talk to my patients about what I would do if my own family members were in this situation. Giving the patient a general reference builds mutual trust and gives the patient confidence. With doctor-patient trust, we doctors have one of the best and most powerful helpers to overcome the disease.
