Tort liability law
Article 58 If a patient suffers damage due to one of the following circumstances, it is presumed that the medical institution is at fault:
(a) in violation of laws, administrative regulations, rules and other relevant medical norms;
(two) concealing or refusing to provide medical records related to the dispute;
(3) Forging, tampering with or destroying medical records.
So the hospital should take full responsibility. Now, it is necessary to preserve the evidence of modifying medical records, coordinate or litigate.
