Obiective To develop an integration profile for hospital clinical system and medical image information system, and discuss relative problems on regional medical image sharing based on the Cross-Enterprise Document Sharing Integration Profile (XDS). Methods As medical image constitutes important information of the patient health record, it is logical to extend the XDS integration profile to include images. The new integration profile for sharing images and image reports between multiple enterprises and the XDS for Imaging(XDS-I) was used. Results The XDS-I profile can be used in medical image sharing system in multiple enterprises. Conclusion The IHE XDS-I can give references for medical imaging regional sharing.

Based on the analysis of dataflow and workflow of hospital HIS?RIS and PACs,this article projects a system integration model in the digital hospital construction.By the design of a typical hospital information system,a method of all the information system workflow integration is proposed and validated,which is based on the HL7 and DICOM.

Objective To focus on the expressiveness and flexibility of OpenSDE: an application that supports recording of structured narrative data. Methods OpenSDE enabled data entry with (customizable) forms based on trees of medical concepts. The relevant scope for data entry could be tailored per medical domain by construction of a domain-specific tree. OpenSDE was intended for structuring narrative data to make these available for both care and research. Results The OpenSDE application was used at two departments in aspects of radiology, neurology, pediatrics, and child psychiatry. Conclusion OpenSDE is superior to traditional text entry method in aspects of correct and full expression and clinical decision support.

One important problem of regional information system in healthcare is the access to electronic patient records across healthcare institute boundaries. The Integrating Healthcare Enterprise initiatively proposes the integration profile of the retrieve information for display that enables a user to retrieve and display patients' related documents cross hospitals. The middleware is added to HIS to realize the cross-hospital data access to clinical information with access authorization and privacy regulations. Besides,the integration of cross-hospital patients' clinical information is achieved based on the realization of Patient ID protocol in different systems.

Objective To further develop SDE for structured documentation of clinical data based on medical ontology. Methods OpenSDE was customized for the broad domain of medical ontology: medical concepts and its descriptors from history taking and physical examination were modeled into a tree structure. Results An expandable EMR system with structured data entry was developed. Conclusion Structured data entry is significant to clinical decision based on EMR.

Objective It is being increasingly recognized that electronic management of health information(eHealth) contributes greatly to safe medical treatment,high efficiency and better quality of health care.Definitive standards are required for medical information systems to share electronic health records.Methods The structure and contents of electronic health records were extensively investigated for sharing standards.The standards were evaluated in their functions and influences to the sharing of electronic health records.Results Suggestions were given to the standards of regional electronic health records.Conclusion Regional electronic health records facilitates individual medical care.

Based on the clinical informatization construction of large comprehensive hospitals , as required by information -based closed-loop management of medical advices , the paper analyzes the objectives and contents of informatization constructization in the closed-loop management of medical advices in modern hospitals , introduces the application effects of closed -loop management of medi-cal advices , and points out that such a management mode is the basis for future development of smart health care .

Electronic Healthcare Record (EHR) is one of the most important part of the medical information system. This paper proposes both the objective of sharing tele-medical information based on PACS and the building plan including the multi- dimensional electronic records integration, the medical PACS grid storage and the electronic authenticated security technique. This study has great significance to the development of eHealth.

Objective To explore the application ways of IHE XDS technology in electronic medical record (EMR) system and develop application system of clinical EMR integration. Methods The clinical EMR integration plan was worked out based on IHE XDS technical framework. Results A EMR solution based on IHE XDS was presented. It was consisted of the components of the clinical Data Entry, XDS Registry, clinical document Repository, EMR application server and the i-node accessing server. The system was tested and the result indicated that the system was effective and scalable. Conclusion IHE XDS profile can be not only used to realize the sharing of EMR documents across multiple hospital, but also support the collection clinical data within a hospital clinical system integration.
