An ontology-based approach for data integration in regionally interoperable healthcare systems

摘要

In order to best utilize the limited resource of medical resources, and to reduce the cost andudimprove the quality of medical treatment, we propose to build an interoperable regional healthcareudsystems among several levels of medical treatment organizations. In this paper, our approaches are asudfollows:(1) the ontology based approach is introduced as the methodology and technological solution forudinformation integration; (2) the integration framework of data sharing among different organizations are proposed(3)the virtual database to realize data integration of hospital information system is established. Our methods realize the effective management and integration of the medical workflow and the mass information in the interoperable regional healthcare system. Furthermore, this research provides the interoperable regional healthcare system with characteristic of modularization, expansibility and the stability of the system is enhanced by hierarchy structure.
