Ambulance out of the scene is not necessary to pull back the patient

Pull back the patient, everything depends on the actual situation, there is no patient, the patient walked away, or has died, you need to sign the car pay, as long as there is a voucher, plus the staff will have a recorded video record, or dismissal of the death of a single, that is perfectly fine, not rigid, no one or the patient is not a problem, but also hard to pull the person over.
