Research On Medical Information System Architecure And Development

Medical Informatics is a rising field of research with Medical Information System as one of its important branches. Although many information systems have been applied in clinical practice, since they are in lack of theoretical guidance, the development has been a disorderly one. The developers mechanically copy the development of information system from other fields to temporarily meet the demand in healthcare institutes, hence the products ever developed are either irrelative or repetitive and can not be integrated. In our country, the systematic research and development of medical information system has just begun in recent years.The establishment and improvement of a theory in this field is an urgent demand. Taking the establishment of a complete set of theory as the long-term target, with integrating distributed heterogeneous systems as the main subject, the thesis has made an in-depth research in the architecture of medical information system both theoretically and practically. The architecture of medical information system for system integration has been constructed and the development platform for medical information system has been designed and implemented. Specifically: A classification and summary is made on the content of theory for medical information system from both medical information and medical information system points of view, hence a theory basis is provided for the personnel in their research, development, maintenance, or use of the medical information system. After an analysis of the architectures of medical information system popular in these days, based on middle-ware theory, a design for the system structure of medical information system is put forward, and the problems in integration have been completely solved in terms of technical platform and medical model. Through an analysis into three schemes for distributed object-oriented technical platform, considering the peculiarity of medicare field, the distributed object-oriented technology platform MUSCLE is designed, and is implemented on the base of integration scheme of CORBA/EJB . Through the study of the standards for medical data exchange/communication, the application view for medical integration is concluded, and the integration model HIM of medical information system is designed on the basis of standard, the scheme for workflow integration, function integration, and interfaceintegration is implemented.The design and implementation of development platform for medicalinformation system is carried out on the base of the architecture for medicalinformation system. On the one hand, the system structure is implemented; onthe other hand, various components are provided for the development ofmedical information system, and repetitive development is avoided.Finally, through the design and implementation of two typical and practicalinformation systems, the effectiveness and rationality of the MUSCLE isproved. One is Digital Radiology System and the other is ECG Center based onASP model.
