3.1 Background analysis:
With the popularization of the Internet and the development of information technology, hospital informatization construction has always been the focus of hospital development. The existing hospital internal network has data interaction delays, low security access levels, and real-time communication verification. These problems directly affect the future development and operation of the hospital. With the development of science and technology and the popularization of applications, especially the development of computer technology and network technology, with the continuous expansion of hospital internal network application requirements, the existing network structure and mode can no longer meet the existing requirements.
The online medical service based on computer network technology has truly realized the prospect of "joint medical care", and the idea of remote consultation among various medical institutions can be further realized, which can effectively solve the clinical business development efficiency caused by the lack of talents in medical institutions in my country Insufficient problem. At the same time, the emergence of computer network technology can also improve the efficiency of other non-clinical businesses in hospitals, such as hospital file management and hospital financial management based on information technology. All in all, actively developing network technology and applying it to hospital information construction and management will help improve the efficiency of hospitals.

With the support of computer network technology, the information construction of the hospital can be carried out in an orderly manner. At present, the information construction of the hospital has spread all over various departments, such as clinical departments, financial departments, and file management departments. The advantages brought by computer network technology, such as automated management, remote control, and improved work efficiency, will largely solve the development problems of various departments of the hospital, and make the hospital gradually get rid of human resource anxiety. With the continuous deepening of the network, some human positions may no longer exist, and network automation management will replace traditional manpower, and better play the functions entrusted by engineers.
Under such a medical scenario, the hospital's future medical costs will be greatly reduced. The decline in medical costs means that patients' medical expenses will be reduced simultaneously. Therefore, this article believes that with the continuous development of hospital informatization, the domestic problems of "difficult to see a doctor" and "expensive to see a doctor" will continue to be alleviated. All in all, actively developing computer network technology and applying it to the construction and management of hospital information will help to reduce the cost of running a hospital.
