Architectural Constraints and Considerations

Secondary Benefits

Use of HL7v3 conforms with the architectural design of Canada's digital health blueprint.

AB MR2009 extends the Canadian specification with the ability to merge and logically delete providers.

HL7v3 messaging does not provide the means to transmit a the history of changes to a provider records.

The PRS XML Messaging specification is proprietary to the registry solution but is shared across several provinces.

Standardizing on MR2009 across EHR applications reduces complexity within the infostructure and for implementers by minimizing variability in models and vocabulary.

Recommendation

Supporting Rationale

AB MR2009 (HL7 v3)The AB MR2009 specification was designed to meet the in-scope use cases for PRS consumers and conforms with the architectural design of Canada's digital health blueprint. It extends the Canadian specification with the ability to merge and logically delete providers.

Architectural Constraints and Considerations

Secondary Benefits

Source systems are not typically EHR consumer systems.

HL7v3 messaging does not provide the means to transmit a the history of changes to a provider records. (UC-6)

The PRS XML Messaging specification is proprietary to the registry solution but is shared across several provinces.

 

Recommendation

Supporting Rationale

PRS XML MessagingThe PRS XML specification was designed to meet the in-scope use cases for PRS source systems. Although the specification is proprietary to the specific provider registry solution used in Alberta it is relatively straightforward to implement.
