The Research And Implementation Of Electronic Health Record Based On HL7

With the development of social economic development and living standards, the people make higher demands on health services [1]. Chinese new medical reform program is to create a practical, shared medical and health information platform. It is an unprecedented opportunity for the construction of health information, and to build regional health information system with electronic health record as a core is an important direction for health information.Based on this background, the paper builds the electronic health record system which is based on the HL7standard. Electronic health record system can not only provide residents with complete personal health information, but also provides a wealth of clinical data source for medical personnel [2]. The introduction of the HL7standard not only make the system exchange data with external agencies,such as the medical insurance system, medical business systems, and so on, but also provide a basis for health information platform to further expand the regional extent.After analyzing the state of the field of electronic health record at home and abroad, this paper summarizes the main features and requirements of the electronic health record system, designs the business processes of this system, paper makes detailed design and implementation of electronic health record system using MVC model and J2EE platform. At the same time, this paper introduces the basic principles of the HL7(Health Level7) standard, describes the archiving information of this system using the HL7RIM model through analysis of the HL7specification documents, establishes an implementing model of constructing and parsing a feasible set of HL7message, and builds HL7engine applied in the sub module of the system after using Web Services technology.
