Digital informatization is an international development trend, and all countries attach great importance to the development of digital informatization. Among the "digital China" in China, "digital medical care" can best reflect China's emphasis on digital informatization.

With the rapid development of information technology, more and more hospitals in China are accelerating the overall construction based on information platform and HIS system to improve the service level and core competitiveness of hospitals.

Informatization not only improves doctors' work efficiency, allows doctors to have more time to serve patients, but also improves patients' satisfaction and trust, and invisibly establishes the scientific and technological image of the hospital. Therefore, the gradual integration of medical service application and basic network platform is becoming a new direction of informatization development of domestic hospitals, especially large and medium-sized hospitals.

Information refers to the objects transmitted and processed through audio, news and communication systems, and generally refers to all the contents spread by human society. People can distinguish different things by obtaining and identifying different information from nature and society, so as to understand and transform the world. In all communication and control systems, information is a common form of communication.

According to the concept of information, people can conclude that information has the following characteristics:

1. The greater the probability P(x) of message x, the smaller the information; Conversely, the smaller the probability of occurrence, the greater the amount of information. As you can see, the amount of information (which we refer to as I) is inversely proportional to the probability of message occurrence.

2. When the probability is 1, everyone knows what happened, so the amount of information is 0.

3. When a message consists of several independent small messages, the information contained in this message should be equal to the sum of the information contained in each small message.
