Realization of integration and working procedure on digital hospital information system

The integrating method and working procedure of a digital hospital information system were discussed in this paper. It adopts a unique modularized structure that allows interplatform data exchange among different hospital information systems (HIS, RIS and PACS) through the seamless integration of the above-mentioned three systems according to the international standards (DICOM, HL7 and TC251). The realization of communication interface standardization, function modularisation, common sharing of medical information resources and adaptation to local circumstances enables the system function, management function, information processing and communication function to be achieved on a complete platform, which provides such advantages as common sharing, openness, security, extensibility and simple operation, and offers completeness to present hospital management and future medical environment. Currently, it is being successfully applied at many hospitals in China such as the 5th People Hospital of Zhengzhou City to realize the digitized, network-dependent and film-independent modern hospital management.
