Hospital medical records are legally binding documents. Once formed, the subject can't be changed, especially the part of the patient's self-description! Doctors will collect the medical history of patients and their families when writing hospital medical records. At this time, patients and their families should tell the truth. After the doctor has written the inpatient medical record within the specified time, he will verify it again and sign it for approval. If you feel that the record is wrong, you can ask the medical record writer and sign it after revision. But once it is signed and approved, it cannot be amended.
