The PS-CA is based on and is closely aligned to the IPS. It addresses both the content of a well formed Patient Summary document using the FHIR standard version 4.0.1, as well as the exchange mechanisms as listed in the Reference Architecture. Version 1.0.0 TI of the specification package has been updated to offer guidance towards a secure, access-controlled exchange of documents over the internet.
The Specifications package for the Projectathon 2023 includes the:
...
Therefore, the Projectathon test cases have been organized into two categories:
| Category 1: Test cases that test individual actor capabilities in isolation E.g., how a system can handle encrypted transactions, how a system can handle a CA:FeX transaction, how a system can handle an OAuth 2 token exchange, etc. |
| Category 2: Complex test cases that group individual actor capabilities with other relevant actor capabilities to simulate real world scenarios. E.g., how a patient summary creator system can submit the document to a repository by using an OAuth 2 integration, etc. |

Participants
Vendors and jurisdictions who plan= to implement the PS-CA Specifications are invited to participate in the Projectathon. In addition, any interested party that has Patient Summaries in their future roadmap are welcome to participate.
Participants of the Projectathon are able to:
- Have the opportunity to be an early adopter and an influencer of the final specification;
- Gain a better understanding of the expected integration patterns for their products;
- Identify dependencies and integration challenges;
- Interact with the jurisdictional teams that will ultimately use their products;
- Ensure quality for the benefit of clinicians and patients;
- Accelerate their readiness for implementation;
- Save time and money through a harmonized pan-Canadian approach;
- Get familiar with the validation/testing processes and tools; and
- Help achieve our collective goals of developing a quality national standard.
Additionally, through participation in the Projectathon, participants were able to prepare for practical applications of the PS-CA Specifications.
Approach
A suite of virtual tools, collectively referred to as Gazelle, will be deployed to support the free, 4-day remote testing event from March 6-9, 2023. Gazelle provides vendors an opportunity to validate the role they will be playing in an ecosystem and ensure they are able to satisfy the interoperability requirements. Furthermore, Gazelle offers several self-serve, self-test and innovation opportunities for jurisdictions and vendors to test their alignment to the represented integration profiles.
The Projectathon event was organized by Infoway with support from a world leader organization in the space - IHE Catalyst.
Preparation and Requirements
In preparation for the Projectathon, Infoway and IHE Catalyst will:
- Host training webinars;
- Develop a FHIR document viewer;
- Deploy an OpenAPI browser for both interface specifications (MHD and CA:FeX);
- Develop clinical scenarios that identified the required test data for the Projectathon;
- Offer helpdesk support prior to and during the Projectathon; and
- Publish a report on learnings after the Projectathon.
Participants are required to:
- Register for the event
- Attend training webinars
- Review training materials
- Complete pre-Projectathon and connectivity testing
- Validate test cases and clinical scenarios
- Integrate to Gazelle platform
- Create test records
- Implement APIs
- Prototype FHIR transactions
- Prototype the PS-CA FHIR document
- Prototype export of FHIR document
Interoperability Specifications
...
pan-Canadian Patient Summary (Available here: PS-CA v1.0.0 TI)
The PS-CA is composed of four documents, as listed below.
In addition, you may wish to review this diagram which provides a high-level view of relevant Integration Profiles to support the PS-CA project. This view contains a superset of profiles that offer alternatives to exchanging Patient Summaries, depending on Jurisdictional service type and availability. Mandatory and optional capability support is described in the sequence diagrams associated with each Use Case analysis.

Pre-Projectathon Preparations
For successful participation in the Projectathon, pre-Projectathon tests and connectivity tests are important.
The purpose of the Pre-Projectathon tests are to help vendors:
Test their IHE profile implementation in their system using the virtual systems in Gazelle to find and fix issues;
Improve the quality of their tests prior to the Projectathon; and
Help familiarize themselves with the Gazelle tool prior to the Projectathon, including how to access and use Gazelle simulators to perform the tests.
The Pre-Projectathon Test period will be open from January 15 - February 28, 2023. A Pre-Projectathon Test webinar was held on February 17, 2022 at 11AM ET. During this webinar, participants were shown how to access and use Gazelle in order to perform the tests.

As part of the pre-Projectathon testing, participants will be required to conduct connectivity testing. The purpose of a Connectivity Testing period is to check, in advance, whether participants' systems are configured and ready to communicate with other vendor systems during the Projectathon event. A Connectivity Testing webinar was held on March 1, 2022 at 11AM ET.
