Yes • One significant gap is DSS will tie to SOAP. There is significant industry movement towards REST.

• DSS has 2 levels, one is model of the service which is implementation agnostic. Could support standard with implementation based on REST, but it would have to be developed.

• DSS is designed to be able to support patient data, unlike Infobutton.

• Has broader scope than Infobutton

(N) Does not Fit: Exceptions

No • UC1 is not designed to carry patient data

• If CCDA is chosen, would probably have to use related HL7 Clinical statements for the Item Payload bucket.

• If vMR is chosen, would probably have to use the vMR Clinical Statements for the Item Payload bucket

• External options may exist for transforming CCDA request into a vMR component

Yes • Can transform CCDA request into a vMR component from the execution system

• Not everything from CCDA goes easily into vMR, but vMR is designed to easily accept CCDA components

(P) Partially Fits: Context; Response Metadata

(N) Does not Fit: Exceptions

Yes • Fits Clinical; Supporting Evidence; Supporting Resource; Actions data requirements

• Attribute value list is not supported in UC1 schema, however the schema does allow extensions using XSD

• Would use subset of HeD UC1 schema that may require further modifications



(Y) Fits: Clinical;

(P) Partially Fits:


No • There is a profile in IHE that uses DSS and returns IHE as an output. But hasn’t been finalized within IHE

• Lacks the ability to group and organize things the way that UC1 does

StandardSummary of

Findings from UCR Crosswalk

Keep? Rationale





No • Does fit this situation, however CDS Knowledge artifact may be the better option

• UC1 action would need to be modified to represent payload for UC2 regarding vMR

• May need a model agnostic response

No • Some vendors may want to support this as an option, however CDS Knowledge Artifact is the better option

• Adoption of this standard is low, so there is not a driving reason to extend support to it
