We are a group of organizations who have already implemented IHE profiles We recognized the user stories – IHE already addresses them We could leverage existing products and toolkits – it wasn’t scary We can get this done fast

5: Laboratory sends lab results to ordering provider Laboratory may not have a patient ID. If they do, they would likely use XDR on the sending edge. If not: A: Use order number as pseudo patient identifier B: Relax XDR metadata requirements 12: Primary care provider sends patient immunization data to public health Several initiatives within CMS already use XDR on the receiving edge, so this may just be scenario 1.
Straightforward integration with NHIN Exchange One metadata model supports both minimal and extended metadata Developed, maintained, and enhanced through a formal and open process Can work across the continuum of care settings, from small practices to integrated delivery networks
Supports point-to-point encryption; doesn’t currently support non-trusted intermediaries Intended recipient metadata integrated into content container metadata ebXML can look daunting SOAP looks hard
EHRA support NHIN Direct can make it to the real world faster with IHE Maturity of the approach: small changes to XDR are much preferable to inventing something new This is a profile, not just a protocol It’s simple, scalable, and sustainable
