PS-CA Interoperability Specifications (PS-CA Specifications)

• Implementable and testable specifications, based on the IHE International Patient Summary specification and the HL7 IPS Implementation Guide.
• Building blocks to create and share condition-independent and specialty-agnostic patient summaries, irrespective of the condition of the patient or the treatment sought or specialty of the provider delivery care.

PS-CA FHIR Implementation Guide

• Implementable, testable specification for the HL7 FHIR composition that defines the data payload of the PS-CA specification, based on the HL7 FHIR IPS implementation guide.
• Contains information for solution developers to implement the PS-CA content data model using the HL7® Fast Healthcare Interoperability Resources (FHIR®) standard. It describes the data elements & types, cardinality, constraints, and code system references.

PS-CA Companion Guide to Use Cases & Definitions

• Companion document to the PS-CA Specifications that presents the broader context for clinical, business, interoperability and solution development considerations that were discovered during the development of the PS-CA. 
• Defines the healthcare problem that the PS-CA addresses and includes healthcare use cases and interoperability requirements in terms that will be traceable to the content in the pan-Canadian Patient Summary - Companion Guide to Reference Architecture.

PS-CA Companion Guide to Reference Architecture

• Contains background information on the abstracted PS-CA actors and transactions for the Pan-Canadian Patient Summary Interoperable Specifications, describes baseline information on the recommended IHE profiles, and includes links to the IHE source documentation where stakeholders can get additional details on each PS-CA actor and transaction.
• Includes descriptions of alternatives and choices for implementation patterns and ecosystem architectures to support the PS-CA in current state, including sequence diagrams that demonstrate the relationship and dependencies between the PS-CA actors and transactions.

• Addresses standardized sharing of vital patient information for the benefit of health care providers and patients using FHIR based information exchange.
• Similar to, and accomplishes the same objectives as, a Health Information Exchange (HIE).
• The first priority of this specification will be to define a document exchange interface for CA:FeX, clearly defining how a FHIR document can be transacted with a Clinical Data Repository. 

• Provides supporting Reference Architecture for the PS-CA and CA:FeX interoperability specifications.
• An evolving blueprint of service availability that supports a broader interoperability landscape, not limited to patient summaries. 
• A conceptual technical view that provides a common vocabulary and a set of actors and transactions representing typical components in a digital health ecosystem (public and private sector solutions). It is a combination of building blocks adopted from international standards development bodies and Canadian developed implementation patterns.
