PS-CA Library of Profiles


This version of the PS-CA Implementation Guide has been superseded by a newer version. A full list of versions & releases of the PS-CA Implementation Guide may be found at Guides.


PS-CA Structure

A patient summary, as defined in both the IPS and PS-CA specifications, is a document. The Composition (PS-CA) profile dictates the structure of the patient summary document in a way that combines information about the creation of the patient summary (e.g., header information) with clinical information about the patient (e.g., composition sections).

The Composition (PS-CA) profile relies on the capability in FHIR to reference other FHIR resources to establish a link between the Composition resource and the other resources that belong to each of its sections .

All the resources that make up the Patient Summary document (e.g., Compositon, Immunization, Condition, MedicationRequest, etc.) are transported together using a FHIR Bundle. This Bundle SHALL include all the resources that are referenced directly or indirectly by the PS-CA Composition.

List of Profiles in PS-CA Version 1

Pages have been developed for the profiles in PS-CA Version 1. Each of the pages include the:

  • profile differential table
  • extensions (if applicable)
  • description of the differences between this profile and the equivalent IPS profile

Bundle

Bundle (PS-CA)

This profile represents the constraints applied to the Bundle resource by the International Patient Summary (IPS) FHIR Implementation Guide.

Composition

Composition (PS-CA)

This profile represents the constraints applied to the Composition resource by the PS-CA project. A Canadian Patient Summary (PS-CA) document is an electronic health record extract containing essential healthcare information about a subject of care. It is informed by the IPS-UV Composition profile, but differs in its application of MS flags on some of the sections to allow for jurisdictional implementors flexibility in what sections systems must support in order to show conformance to their respective patient summaries.

Header Section

Patient (PS-CA)

This profile represents the constraints applied to the Patient resource by the PS-CA project to represent the minimum expectations for the Patient resource when used in the PS-CA composition profile or in one of the referred resources. It is informed by the constraints of the Patient-UV-IPS profile and the Canadian Baseline Profile

Note: Some elements in the Header section (author, attester, custodian) reference profiles that do not have appropriate equivalents in the current IPS specification, implementers are encouraged to utilize the minimal profiling expectations outlined National Canadian Baseline profiles in these cases:

Medication Section

Medication (PS-CA)

This profile represents the constraints applied to the Medication resource by the PS-CA project to represent a medication in the patient summary. It is informed by the constraints of the Medication-UV-IPS profile and the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of Medication Summary information.

MedicationRequest (PS-CA)

This profile represents the constraints applied to the MedicationRequest resource by the PS-CA project, which is informed by the constraints of the most recent direction of the IPS-UV (September Connectathon Build) and by the constraints of the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of information record of a medication request information in the patient summary.

MedicationStatement (PS-CA)

This profile represents the constraints applied to the MedicationStatement resource by the PS-CA project to represent a record of a medication statement in the patient summary. It is informed by the constraints of the MedicationStatement-UV-IPS profile and the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of Medication Summary information.

Allergies Section

AllergyIntolerance (PS-CA)

This profile represents the constraints applied to the AllergyIntolerance resource by the PS-CA project, which is informed by the constraints of the AllergyIntolerance-UV-IPS profile and the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of Allergies and Intolerances. It documents the relevant allergies or intolerances (conditions) for a patient, describing the kind of reaction (e.g. rash, anaphylaxis); preferably the agents that cause it; and optionally the criticality and the certainty of the allergy.

Problems Section

Condition (PS-CA)

This profile represents the constraints applied to the Condition resource by the PS-CA project, which is informed by the constraints of the Condition-UV-IPS profile and the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of A record of a problem is represented in the patient summary as an instance of the Condition resource constrained by this profile.

Procedure History Section

Procedure (PS-CA)

This profile represents the constraints applied to the Procedure resource by the PS-CA project, which is informed by the constraints of the Procedure-UV-IPS profile and the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of History of Procedure information.

Immunization Section

Immunization (PS-CA)

This profile represents the constraints applied to the Immunization resource by the PS-CA project to represent a record of immunization in the patient summary. It is informed by the constraints of the Immunization-UV-IPS profile and the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of Medication Summary information. It describes the event of a patient being administered a vaccination or a record of a vaccination as reported by a patient, a clinician or another party.

Social History Section

Observation Tobacco Use (PS-CA)

This profile represents the constraints applied to the Observation resource by the PS-CA project to represent Tobacco use assessment in a patient summary. It is informed by the constraints of the Observation-TobaccoUse-UV-IPS profile and the Canadian Baseline Profile to allow for cross-border and cross-jurisdiction sharing of Social History Information.

Observation Alcohol Use (PS-CA)

This profile represents the constraints applied to the Observation resource by the PS-CA project to represent Alcohol use assessment in a patient summary. It is informed by the constraints of the Observation-AlcoholUse-UV-IPS profile to allow for cross-border and cross-jurisdiction sharing of Social History Information. No equivalent Canadian Baseline Profile exists at the time of this draft.

Vital Signs Section

The Vital Signs section in both IPS-UV and PS-CA point to the base R4 FHIR profiles for vital signs.

Implementors are expected to meet the base expectations for receiving/producing content modeled after the FHIR vital sign profile, however it is up to the jurisdiction to determine which of the vital sign sub-profiles from the base R4 specification they are expecting to support in the first version (e.g., BMI, height, weight, blood pressure, heart rate, etc.).

Other Sections

Remaining sections that are identified in the Composition PS-CA are considered out of scope for the profiling efforts of Version 1. The following sections remain in the Composition profile but maintain their original references to the IPS-UV profiles: MedicalDevices, Results, PastIllnessHx, FunctionalStatus, PlanOfCare, PregnancyHx, AdvanceDirectives.

These sections will be profiled, along with a new section for FamilyHistory as part of PS-CA Version 2.
