A number of hospitals in Shanghai are piloting the development of an EHR solution based on a grid concept with a service-oriented architecture (SOA). The first phase of the project targets the Diagnostic Imaging domain and allows seamless sharing of images and reports across the multiple hospitals. The EHR solution is fully aligned with the IHE XDS-I integration profile and consists of the components of the XDS-I Registry, Repository, Source and Consumer actors. By using SOA, the solution uses ebXML over secured http for all transactions with in the grid. However, communication with the PACS and RIS is DICOM and HL7 v3.x. The solution was installed in three hospitals and one date center in Shanghai and tested for performance of data publication, user query and image retrieval. The results are extremely positive and demonstrate that the EHR solution based on SOA with grid concept can scale effectively to server a regional implementation.
