Changelog

Changelog

v1.0.0 September 25 2024 published version

v0.5.0 updates

  • Updated CapabilityStatement to specify DSH/Connector Plane security and generate an OpenAPI Specification via HNZ Digital Tooling
  • Updated OpenAPI specification links
  • Documented Resource-Context custom header requirements in developer guide page, CapabilityStatement and OpenAPI specification
  • Upgraded NZBase IG dependency to v3.1 (current). Due to this update, the NZ Base NzPatient profile now contains the interpreter-required extension which this IG re-uses (instead of the old local extension named interpreterRequired which has been dropped). Example patient instances updated to use the NZ Base extension.

v0.4.9 updates

  • Updates to consent documentation.
  • The coding of relationship type 'Other' has changed to use the code #O (upper case letter 'O') from the FHIR/HL7 relationship type codes.

v0.4.8 updates

National system (RFCCS) identifiers

  • Consolidated national identifier system type codes into the IG CodeSystem (formerly a separate CodeSystem)
  • All national identifiers (slices on resource.Identifier) now have the system Url set to the HISO standard NamingSystem value https://standards.digital.health.nz/ns/rf-ccs-id

eSAM identifiers

The patient's address in the example diagnosis encounter now has an eSAM identifier with system Url set to the HISO standard NamingSystem value https://standards.digital.health.nz/ns/nz-address-id

Examples

  • In Patient with care team, membership has been adjusted to include a care team member with role/relationship type 'Other' using the correct coding.

Doc

  • Corrected Consent FHIR data models
  • Revised Terminology documentation page

v0.4.7 fixes

Renamed capability statement instance. Reinstated Consent.performer in consent examples.

v0.4.6 Updated canonical Url

The canonical base Url for the IG has been updated to https://fhir-ig.digital.health.nz/rheumatic-fever for publishing at the official HISO IG site.

This IG now appears in the HISO Implementation Guide index (UAT)

v0.4.5 Coding fixes and general updates

Classifiers for OAUTH scoping of RF data

Filtering classifiers added to various RF resource types to enable OAUTH scoping as follows:

  • Appointments have .serviceCategory set to $sct#58718002
  • Encounters have .type set to $sct#58718002
  • MedicationStatements have .category set to $sct#58718002

RF resource tagging

  • To enable OAuth scoped access controls, all RF resource instances should be tagged with the RF SNOMED code (meta.tag.code=58718002)
  • The RF profiles on CarePlan, Condition, CareTeam, Observation (DiagnosisGroup), MedicationRequest and Patient resource types now have an invariant requiring the RF SNOMED code tag.
  • All example instances have been RF-tagged
  • A tagging section has been added to the data standards page.

Consolidation of SNOMED NZ Edition terminology into one local CodeSystem

Testing has shown that applications cannot practically use codes defined in the NZ SNOMED edition because the New Zealand Health Terminology Service (NZHTS) is unable to support lookup and validation of these codes. (This stems from SNOMED affiliate licensing restrictions affecting the NZ Edition.)

As NZ SNOMED terms are in effect unusable for NZ applications, all these codes have been brought into a CodeSystem in the IG, so the IG itself defines the codes.

The IG now has a single local CodeSystem which consolidates all the special codes needed for New Zealand rheumatic fever FHIR data representation.
This CodeSystem includes codes which previously sat in their own systems eg. the RF diagnostic certainty codes.

The various ValueSets used throughout this IG now draw all their codes from the new common IG CodeSystem, or from applicable public terminology systems (http://snomed.sct/info, http://nzmt.org.nz).

The following IG artefacts have changed to draw some or all of their codes from the new common local CodeSystem:

  • RFConditionDiagnosticCertaintyValueSet
  • RFConditionRHDSeverityValueSet
  • RFConditionSummaryDiagnosisValueSet
  • RFDiagnosisGroupValueSet
  • RFRelatedPersonRoleValueSet (renamed from RFCareTeamParticipantRoleValueSet)
  • RFMedicationRequestMedicationFrequencyValueSet (renamed from RheumaticFeverMedicationRequestMedicationFrequencyValueSet)
  • RFMedicationAllergyValueSet (renamed from RheumaticFeverMedicationAllergyValueSet)

All instance examples featuring NZ-specific codings now use the local codesystem Uri in this IG instead of a SNOMED NZ edition Uri

DiagnosisGroup (Observation) profile strengthened

The DiagnosisGroup (Observation) profile now requires:

  1. All Observation instances (group-level) to be coded using local codes instead of SNOMED codes (however, the same code numbers are used as per the SNOMED terms.)
  2. All Observation component items are to be coded from a new ValueSet RFDiagnosisObservationCodingValueSet which draws all the diagnosis SNOMED codes plus one special local code #448021000210106 (Indolent carditis (disorder))

Revised categories in CarePlans and Conditions

The following profiles now require use of the local code #rf-nz to categorise all instances:

  • CarePlan profile requires instances to be categorised #rf-nz (was SNOMED #320721000210102)
  • Condition profile requires instances to be dual-categorised #rf-nz, SNOMED #58718002 (was SNOMED category only)
  • CareTeam profile requires instances to be categorised #rf-nz (was SNOMED #320741000210108)

Miscellaneous fixes

  • Altered relationship role ValueSet to include all codes from the (as per binding of FHIR RelatedPerson.relationship)
  • Medication statement examples - removed incorrect profile reference
  • Fixed a publisher error on the example Uri for the code system of the national identifier slice on identifier in CarePlan, CareTeam, Condition and Observation profiles.
  • Adjusted patient care team for example SageWestbrookAndWhanau to demonstrate a legal guardian type contact.

v0.4.4 CarePlan profile status history and examples updates

Profiles

  • RF CarePlan profile
    • Added a new complex extension to capture CarePlan status change with dates and reasons.
    • Removed the old specific extensions which tracked the reason a CarePlan instance entered on-hold or closed status.

Examples

  • Reworked Encounter example instances to use official test data
