How to Provide Feedback: 

  • All Collaborators are invited to document their comments using the PS-CA v2.0.0 DFT-preBallot spreadsheet, available here
  • Send an email to [email protected], with Subject Line "PS-CA", including the PS-CA v2.0.0 DFT-preBallot  spreadsheet as an attachment.
  • We kindly ask that each organization submit all comments within one spreadsheet submission. 
  • Upon submission, you will receive an acknowledgment email with a reference number. Infoway team will prepare dispositions for each comment, reaching out to submitters only when necessary, versus a full review of each comment at the PSWG.
  • Mid-October: PS-CA v2.0.0 DFT-Ballot will be published for stakeholders to begin working with, in preparation for the next Projectathon/Connectathon in Feb 2025.
  • December to January: Formal balloting. This plan will allow stakeholders to gain experience with this release between Oct-Dec and provide their feedback in a formal ballot cycle scheduled to occur before the Projectathon.

 Release Notes:


FHIR Implementation Guide Change Log

  • Changes to the FHIR Implementation Guide are documented in the Canadian FHIR Registry, PS-CA project, located here.

PS-CA Specifications

  • Updated the Glossary to include definitions for On-Demand and Shareable Health Links (SHL). 
  • Updated the PS-CA High-level Release Roadmap in the Preface to outline a strategic progression from initial, limited production rollouts to a comprehensive implementation model capable of supporting international exchanges of the patient summary. 
  • Added a PS-CA v2.0.0 overview section to the Preface. 
  • Updated the IPS-UV/PS-CA figure to include data domains that are part of New Brunswick's PS-CA implementation and updates to reflect changes to the other jurisdictional implementations. 
  • Added three new data domains: Advanced Directives, Pregnancy, and Plan of Care. These profiles are optional. 
  • Updated existing data domains to align with IPS.
  • Updated PS-CA Use Case Overview to include the purpose of each use case and removed the use case actor's description and mapping table, as the use case actors for each use case are defined in the Companion Guide: Use Cases and Definitions. 
  • Updated the design constraints and assumptions; removed the constraint of PS-CA being created solely from local data sources. The On-demand use case added in this release allows for a PS-CA to be created from local and external data sources. 
  • Updated the Core Interoperability Specification Requirements section to include separate pages for each use case for actor mapping to interoperability specifications.

Companion Guide: Use Cases and Definitions

  • Added two new use cases: UC-04: HCP Requests PS-CA On-Demand and UC-05: Patient Mediated Access and Exchange of their Patient Summary. 

Companion Guide: Reference Architecture

  • Sequence Diagrams for UC-01, UC-02, UC-03 updated with simplified legend by removing unused items and utilize either Interoperable Transaction or Non-Interoperable Action to categorize system behaviours and aligned with CA:FeX v2.1.0 DFT-preBallot naming scheme

  • Sequence Diagrams for UC-04 and UC-05 added

  • CA:FeX links updated to point to v2.1.0-DFT-preBallot where applicable

  • Reference Architecture (RA) links updated to point to v0.2.0 DFT-preBallot where applicable
