To share data with other users and systems in your network, it must be sent to a GRHID Server to be indexed and organized. GRHID Servers use a number of different protocols for receiving information in order to address the different needs and capabilities of each healthcare organization.  We will continue to add any new standards that are adopted and/or mandated by the healthcare community (for example: see HITSP, CCHIT, and IHE) to ensure that we remain compatible with other industry solutions. The options for adding information to a GRHID Server are as follows:

HL7 Messaging Standard Version 2.x (HL7 2.x)

GRHID Servers use HL7 2.x to add clinical data to the database.  Messages are received via socket-based communications using either the standard (pipe-delimited) encoding or XML encoding.  Messages can also be received via SOAP web services.

Clinical data received via HL7 communications is added to the data repository along with clinical data broken out from electronic documents in order to create a more complete picture of each patient’s health. 

Web Services for Continuity of Care (WS-CC)

WS-CC provides a simple, powerful way to transfer entire data sets in the Continuity of Care Record (CCR) format using a single transaction. The CCRs are retained for audit and non-repudiation purposes, and are also available to the next provider in the chain of care. The data objects in the CCR are also broken out so they can be dynamically re-aggregated into new CCR data sets as requested, or so that the data can be sent to another system in an HL7 message.

The operation for transferring a CCR to a GRHID Server is PostCCR. Any system that has CCR export capability can generate the necessary web service client in minutes using the WS-CC WSDL, which is compatible with both Java and the .NET framework.  For more information on WS-CC, see the GRHID Demo.

Cross-Enterprise Document Sharing (XDS)

GRHID Servers support the IHE Cross-Enterprise Document Sharing Integration Profile for sharing of any type of electronic clinical document. In XDS terms, a GRHID Server acts as both a document registry and a document repository.
