Legal analysis: Medical record materials are the synthesis of words, symbols, charts, images, slices and other materials formed by medical personnel in medical activities. The signature of medical staff in medical records represents the medical staff's diagnosis and concern for the patient's condition. On the one hand, the phenomenon of signing on behalf of medical institutions is not standardized, on the other hand, it also reflects the medical staff's weak awareness of legal risks. If the signature is signed on behalf of others without authorization and is not ratified by the principal afterwards, it will have no effect on the principal and the actor will bear the responsibility. If there is a signature legally authorized by the client, the client shall bear the responsibility.

Legal basis: Article 8 of the Basic Specification for Medical Records Writing should be written in accordance with the provisions and signed by the corresponding medical personnel. The medical records written by medical practitioners and interns shall be reviewed, revised and signed by medical personnel registered in this medical institution. Medical institutions shall, according to their own actual situation, write medical records after confirming that medical personnel are competent for their professional work.
