Pre-hospital medical emergency institutions were established in the 195s, and are often called emergency centers or emergency rescue centers. There are four main modes of operation: one is independent mode, which means that the management and operation of emergency centers are completely independent and have legal personality, with independent financial accounting, and the emergency centers are responsible for receiving emergency calls and delivering patients to hospitals; Second, the relying mode, in terms of management system, the emergency center belongs to an independent institution, but it is located in a hospital, and some emergency personnel, ambulances, emergency equipment and expenses are solved by the hospital, and the government and the hospital invest together to solve the operating costs of the center. Third, the relying mode, not as an independent institution, is not only located in a hospital, but also all emergency personnel, ambulances, emergency equipment and expenses are solved by the hospital. It belongs to a department of the hospital: the fourth is the command mode. The emergency center is an institution with an independent legal person, but its function is only to accept emergency calls and dispatch ambulances and personnel from other hospitals to the scene for emergency treatment.
all parts of the country choose modes according to local conditions. The emergency centers in Beijing, Shanghai, Wuhan, Tianjin and Kunming are independent modes, the emergency centers in Chongqing are dependent modes, the county-level emergency stations are often dependent modes, and the emergency centers in Changzhou, Shenzhen and Chengdu are command modes. Over the years, people have been arguing about the advantages and disadvantages of the above models. In recent years, the independent model is ideal, and there are 6 independent models in 11 cities in Zhejiang Province.
