A doctor may, when he is unable to continue to treat a patient for one reason or another, delegate another doctor and the same competence to him. The patient and his patients usually look at the doctor for a look of some hesitation and suspicion. If, during the course of the disease, there is confusion between the doctor and the doctor, the original doctor will be aware of the patient and his parents. In fact, a doctor who has a colleague who has the same qualifications does not have any responsibility in the event of injury to the patient, provided that the doctor shows that the agent is not the original doctor, but an alternative.
