Sequence Diagrams for select alternate flows

Illustrative alternate flows with a central system based on but not limited to additional and alternate flows defined in UC-04: Referral to Central Access and Triage (CAT).

Please see Single Entry Models for additional information about why there is multiple service requests (SRs) referenced in these flows.

The section below provides guidance on how to read the sequence diagrams:

• The green swim lane provides a simplified view of the actors and transactions that are not explicitly illustrated on the diagram. The Foundational Profiles defined in the Reference Architecture are referenced as required. See the Reference Architecture Release Information page for more information about released versions. These integration profiles are informative options to satisfy pre-requisite business requirements suggested for the particular use case.
• The blue swim lanes group sequence of processes (along with their required actors and transactions) that are needed to occur to satisfy this particular use case. These are to be read from left to right and top to bottom. Note that the sequence diagrams are not explicitly calling out whether the processes are synchronous or asynchronous, and in certain cases it may depend on the specific implementations.
• The actors and corresponding transactions in red, represent the technical actors and transactions that are the bases to achieve interoperability between the different clinical systems.
• For more information on core IHE Profiles and specific Canadian implementation guidance, refer to the Reference Architecture.
