GRHID Servers provide a single point of access to find information throughout the network. A number of different protocols for information access can be used, depending on the 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 retrieving information from a GRHID Server are as follows:

Web Services for Continuity of Care (WS-CC)

WS-CC enables users to retrieve static Continuity of Care Records (CCRs) as well as build them on the fly with the information requested using a powerful query-by-example mechanism that hides the underlying database schema, allowing users to specify search criteria based on the CCR standard, without having to know XQuery. Information that is added to a GRHID Server via HL7 may also be retrieved using WS-CC. Information is always returned in the CCR format, so it can be imported into most EHR (Electronic Health Record) systems.

WS-CC includes three simple data access operations:

• GetCCR – Retrieve a specific CCR
• SearchCCR – Find a CCR based on any clinical search criteria
• BuildCCR – Build a CCR on demand from aggregated clinical data

Any system that has CCR import 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 this, 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.

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

GRHID Servers use HL7 2.x to "push" clinical information to other systems on demand. Messages are sent via socket-based communications using either the standard (pipe-delimited) encoding or XML encoding. Information that is received via WS-CC can be sent back out using HL7.
