Abstract
Shanghai is piloting to develop an EHR system to solve the problems of medical document sharing for collaborative healthcare, the solution of which is considering to following IHE XDS (cross-enterprise document sharing) and XCA (cross-community access) technical profiles as well as combined with grid storage for images. The first phase of the project targets text and image documents sharing cross four local domains or communities, each of which consists of multiple hospitals. The prototype system was designed and developed with service-oriented architecture (SOA) and Event-Driven Architecture (EDA), basing on IHE XDS.b and XCA profiles, and consists of four level components: one central city registry; the multiple domain registries, each of which is for one local domain or community; the multiple repositories corresponding to multiple local domain registries; and multiple document source agents, each of which is located in each hospital to provide the patient healthcare information. The system was developed and tested for performance evaluation including data publication, user query and image retrieval. The results are extremely positive and demonstrate that the designed EHR solution based on SOA with grid concept can scale effectively to serve medical document sharing cross-domain or community in a large city.
