After the injured in the traffic accident was treated, the doctor said he could be discharged from the hospital, but the injured refused to be discharged. What should I do?

I am a police officer who handles traffic accidents. This kind of situation happens very often here. It would be better if the doctor says that the patient can be discharged and is willing to issue a diagnosis certificate to indicate that the injured person has completed treatment. Well, if you have this certificate in hand, you can refuse to bear the medical expenses from the date of the certificate, and tell the accident handling police officer about this situation

Secondly, if the doctor refuses to issue the certificate, If you want to prove it, go to the traffic police and ask the traffic police to talk to the injured. Tell the injured that long-term hospitalization is not good for the body. Taking medicine or injections are not good for the body. Taking too many radioactive films for examination can also cause serious harm. It would be better for the injured to know that they would be discharged from the hospital.
