Key Differences between the IPS-UV and PS-CA

Must Support Differences:

The following elements are considered Must Support in the Medication (IPS) profile that are relaxed in this version of the PS-CA profile:

  • Medication.ingredient and sub-elements

    Note: Systems that support these elements are encouraged to send them in patient summaries

Cardinality Differences:

There are no cardinality differences between this profile and IPS-UV

Vocabulary Differences:

Terminology Guidance: In Canada, CCDD is the preferred binding type for medication codes. However, for broader international comprehension, it's recommended that, where mappings exist, implementers also include IPS free-set concepts alongside CCDD. This approach aims to balance national preferences with the need for international interoperability. Additionally, systems have the flexibility to send other Canadian codes, such as SNOMED CT CA, DIN, and NPN.

Other differences between the IPS and PS-CA Include:

  • Data type profiles (e.g., CodeableConcept) and reference targets (e.g., Patient) replaced with PS-CA equivalents when appropriate
