This kind of case can only be a lawsuit of breach of contract or medical malpractice, which is a special form of personal injury compensation. In addition, the burden of proof in breach of contract litigation lies with the patient, which is more difficult, and the burden of proof in medical malpractice litigation lies with the doctor. If the doctor can't provide the operation record, which will affect the identification, the medical association will not accept it. In this way, according to the rules of evidence in civil litigation, the doctor will bear the adverse consequences of not providing evidence.
