1. In medical lawsuits, hospitals and patients are in an unequal position, and patients are in an absolutely disadvantaged position. Moreover, the procedures are complicated, time, energy and finances, and many patients cannot afford it, so it is not a very important medical treatment. Generally speaking, patients are unwilling to litigate for damage, so I can understand your mood and choice.
2. As long as you can prove that either the hospital operates beyond its scope or the attending doctor practices medicine without a license, the hospital is at fault. On the basis that the hospital is at fault, you can prove two more facts: one is the fact that your mother once received medical treatment in the hospital, and the other is the fact that your mother's body was damaged. If these two points are proved, the hospital will have suffered medical damage and should be liable for compensation. In this case, you do not need to apply for a medical malpractice appraisal.
3. After the promulgation of the Tort Liability Law, medical damage does not necessarily require medical malpractice. As long as the hospital violates the relevant national medical regulations and industry management standards, there will be medical negligence (even if (No medical malpractice occurred during treatment error). In this case, if the patient's body is harmed, the hospital will be responsible for compensation.
4. For specific legal provisions, you can check Chapter 7 of the Tort Liability Law. This chapter specifically stipulates liability for medical damages.
