Research level
In informatics, there may be three different research levels: basic computer science, applied method informatics and applied informatics. The development and research of medical information system mainly belongs to the third level. The more powerful and comprehensive the software developed by the Institute of Computer Science is, the more it can be used to study its application methods in medical informatics. Of course, in this highly specialized research, professional knowledge is needed.
data standard
Information technology has been paid more and more attention in medical institutions and has been widely used. How to use information technology to better serve the hospital's medical treatment, scientific research and teaching has attracted more and more attention. Medical informatics came into being under this background. It is defined as "a discipline involving information processing and information exchange in medical practice, education and scientific research" internationally, and 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.
electronic medical record
Computerized medical record is an important research direction of medical informatics. Refers to the electronic medical record stored in a system, which can support users to obtain complete and accurate information; Prompt and warn medical staff; Give clinical decision-making services; Connection management, books and periodicals catalogue, basic clinical knowledge and other equipment. The advantage of electronic medical record is that the complete electronic medical record storage system supports multiple users to view at the same time, which ensures the enjoyment and exchange of personal medical information. Through the internet, doctors can obtain patients' electronic medical records at home or anywhere in the world at any time. At the same time, different users can be given different information query rights, thus ensuring the safety of medical records. Authorized users can only view appropriate medical records at appropriate times.
Information tool foundation
In addition, electronic medical records are no longer passive medical records. By integrating image information, writing papers can provide real-time medical monitoring, drug dose inquiry and other functions. Electronic medical record has become the basis of emerging information technology and information tools. Electronic medical records can be roughly divided into stand-alone electronic medical records and online electronic medical records. The advantage of online electronic medical record lies in using ASP server to provide global service, and ASP supplier to solve security and data integrity; The disadvantage is that the data is not on the computer where the doctor works.
Standardization of medical terms
Although the medical profession has invested heavily, there are still many problems to be solved urgently in electronic medical records. First of all, the input interface of medical record data is still not simple enough; Secondly, electronic medical records need unified medical terminology standards. The National Library of Medicine has developed a unified medical terminology system, which contains nearly one million terms describing medical concepts. Once the system is popularized, it will greatly promote the standardization of global medical terms.
