Medical informatics is devoted to studying the application of data information and knowledge in the medical field.

Medical informatics (also known as health informatics or medical informatics) is an interdisciplinary subject of information science, medicine and health care. It studies related resources, designs and methods to optimize the acquisition, storage, retrieval and utilization of health and biomedical information. As a new frontier interdisciplinary subject, the tools used in medical informatics include not only computer and informatics technology, but also clinical guiding principles, corresponding medical terms and information exchange system as a platform.

Medical informatics includes some subordinate sub-fields, such as bioinformatics, pharmacoinformatics, public health informatics, medical graphic informatics and so on. The term medical informatics began in the late 1970s. Before that, it was expressed in other terms, such as medical computer science, medical information science, computer in medicine, health informatics and more professional terms such as nursing informatics and dental informatics.

Information technology has been paid more and more attention by medical institutions and widely used. How to use information technology to better serve the medical treatment, scientific research and teaching in hospitals has attracted more and more attention. Medical informatics came into being under this background, which is defined as "a discipline involving information processing and information exchange in medical practice, education and scientific research" internationally.

It is a new interdisciplinary subject of medicine, computer science, artificial intelligence, decision-making, statistics and information management. The latest progress in medical informatics research includes electronic medical records, hospital information systems, decision support systems, image information technology, telemedicine and Internet, and data standards.

Medical informatics is widely used, involving many fields. The following are some specific applications of medical informatics:

1, electronic medical record and clinical decision support system

2. Drug design and discovery

3. Genomics and protein Genomics.

4. Clinical trial design and data management

5. Biomedical image analysis and processing

6, disease prediction and risk assessment

7. Analysis and mining of medical and health big data.

8. Telemedicine and mobile medicine

9, medical education and science popularization

These applications are helpful to improve the diagnosis and treatment effect, optimize the allocation of medical resources, promote the research and development of new drugs, and accelerate the transformation and application of cutting-edge technologies such as genomics and protein genomics in the medical field.
