Medical service informatization is an international development trend. With the rapid development of information technology, more and more hospitals in China are accelerating the implementation of the overall construction based on the information technology platform, HIS system, in order to improve the level of service and core competitiveness of the hospital. Informatization not only improves the efficiency of doctors, so that doctors have more time to serve patients, but also improves patient satisfaction and trust, and invariably establishes the hospital's image of science and technology. Therefore, the gradual integration of medical business applications and basic network platforms is becoming a new direction for the development of informatization in domestic hospitals, especially large and medium-sized hospitals.
Medical informatization, i.e., digitalization, networking and informatization of medical services, refers to the collection, storage, processing, extraction and data exchange of patient information and management information between hospitals as well as between departments belonging to hospitals and meeting the functional requirements of all authorized users by means of computer science and modern network communication technology and database technology. According to the international unified medical system informatization level division, the construction of medical informatization is divided into three levels: hospital information management system, clinical information management system and public **** health informatization.
Most hospitals in China are still at the stage of building hospital information management systems, i.e., hospital information management systems centered on pricing/charging systems and financial systems. The Ministry of Health's "Twelfth Five-Year Plan" clearly states that health informatization is an important task in deepening healthcare reform. The Ministry of Health has preliminarily determined the roadmap for China's health informatization construction, referred to as the "3521 Project", that is, the construction of the national, provincial and municipal health information platforms, strengthen the public **** health, medical services, the new rural cooperative, the basic drug system, the comprehensive management of the five business applications, the construction of the health record and the electronic medical record of the two basic databases and the construction of a dedicated network.
