The so-called emergency green channel refers to the hospital to provide fast and efficient service system for patients with acute and critical illnesses. The scope of green channel treatment includes all kinds of critical patients who need to be rescued immediately; “three no” people. Green channel procedure: As soon as the ambulance arrives, the triage nurse and nurse guide/nurse immediately push the flat cart to the side of the ambulance and assist the family to lift the patient onto the flat cart, while the nurse understands the simple medical history and symptoms and decides whether the patient should be resuscitated in the resuscitation room according to the condition. Those who are determined to be in need of resuscitation are immediately pushed into the resuscitation room. The ambulance stops at the door of the resuscitation room, about 5 m away, to ensure that the patient enters the resuscitation room at the first time. The nurse in the resuscitation room immediately measures the patient’s vital signs, administers oxygen, monitors, and opens intravenous access, while the doctor on duty in the emergency room immediately interviews the patient and conducts a comprehensive physical examination, makes a preliminary diagnosis, and decides whether to open the green channel according to the patient’s condition. If the patient needs to do auxiliary examinations, if the condition allows moving, he/she will be accompanied by the medical guide and the doctor on duty; if the condition does not allow moving, bedside examinations will be performed in the resuscitation room; ultrasound, X-ray, laboratory tests for blood, etc. Doctors of each auxiliary department will arrive at the resuscitation room within 5 minutes after receiving the invitation of bedside examination in the resuscitation room. The procedures of registration, examination, treatment and medication are simplified, with examination first and medication first, followed by supplementary payment and medication collection, etc. If there is no family member, the guide doctor or nurse will do it for them. Patients entering the green channel will present valid documents (or no documents if their condition is critical), and the second-line doctors in the emergency department will be responsible for registering their condition and the fees owed, and will stamp and sign on each examination and treatment sheet, and the relevant auxiliary departments will be given priority examination with the green channel seal on the examination sheet. If the patient needs to be hospitalized, the second-line doctor of emergency medicine will also sign and stamp the hospitalization notice, and the hospitalization department will see the green channel seal and complete the hospitalization procedures as quickly as possible. The doctor on duty will contact the relevant departments by telephone in advance, and the doctor on duty and the medical guide will accompany the patient to the ward and do the handover procedures. If the condition involves multiple departments or requires emergency surgery, the emergency doctor on duty will call the relevant departments in the rescue room for consultation, and the consulting physician must arrive within 10 minutes to study the condition and treatment plan together, and if emergency surgery is required, all preoperative preparations, such as placement of gastric tube, urinary catheter, blood preparation, preoperative conversation and signature, will be completed in the rescue room, and the patient will be accompanied by the doctor and pushed to the operating room directly. All the expenses incurred by patients who enter the emergency green channel in various medical and technical departments before hospitalization are recorded by the second line of emergency medicine in a special “patient’s unpaid fee book”, and the hospital has a special cost recovery office with a special person responsible for collecting the fees, and relevant records are reported to the hospital leadership. In other words, ordinary patients cannot apply for the green channel, and they have to pay for the green channel as well.
