Analysis of HL7 EHRS Functional Model and Suggested Applications in China

摘要

HL7 electronic health record system (EHRS) functional model is an international standard which gives scientific instructions for EHRS design and implementation. It has the features of technological irrelevancy, requirement hierarchy and functional comprehensiveness. It is composed of overarching, care provision, care provision support, administrative support, population health support, record infrastructure and trusted infrastructure. This paper describes the functionalities of each section in detail. To apply this functional model, the history of Chinese health information system construction is reviewed and the weakness is analyzed as a basis. Then this paper gives suggestions on the construction of health information system in China: to enhance the functionality of healthcare systems, to enhance the information network function of regional health information network (RHIN), and to redesign the trust architecture of RHIN.
