Medical Informatics is dedicated to the study of the application of data information and knowledge in the field of healthcare.

Medical Informatics (also known as Health Informatics or Medical Informatics) is an interdisciplinary field at the intersection of information science, medicine, and health care. It examines relevant resources, designs and methods to optimize the acquisition, storage, retrieval and utilization of health and biomedical information. Medical informatics, as an emerging cutting-edge interdisciplinary discipline, uses tools that encompass not only computers, informatics technologies, but also clinical guidelines, appropriate medical terminology, and information communication systems as the platform for implementation.

Medical informatics includes a number of subordinate subfields, such as: bioinformatics, pharmacoinformatics, public **** health informatics, medical graphic informatics and so on. The term medical informatics began in the late 1970s. Prior to this time it was expressed in other terms such as medical computer science, medical information science, computers in medicine, health informatics, and more specialized terms such as nursing informatics, dental informatics, and so on.

Information technology is being increasingly emphasized and widely used in healthcare organizations. How to use information technology to better serve the hospital's medical, scientific research and teaching, has become increasingly concerned. Medical informatics has emerged in this context, which is defined internationally as "a discipline involving information processing and information exchange in medical practice, education, and scientific research",

is an emerging cross-discipline of medicine, computer science, artificial intelligence, decision-making, statistics, and information management. Recent advances in medical informatics research include electronic medical records, hospital information systems, decision support systems, imaging information technology, telemedicine and the Internet, and data standards.

Medical informatics has a wide range of applications in a variety of fields. The following are some specific applications of pharmaceutical informatics:

1, electronic medical records and clinical decision support systems

2, drug design and discovery

3, genomics and proteomics research

4, clinical trial design and data management

5, biomedical image analysis and processing

6, Disease prediction and risk assessment

7, Healthcare big data analysis and mining

8, Telemedicine and mobile healthcare

9, Medical education and popularization of science and technology

These applications can help to improve diagnostic and therapeutic efficacy, optimize healthcare resource allocation, promote the research and development of novel medicines, and accelerate the translational application of frontier science and technology in the medical field, such as genomics and proteomics.
