Release Notes

v0.2.0 (02/09/2025)

  • Updated to use the UK-Core-Observation-Lab profile for representing test groups (i.e. batteries, panels and profiles) rather than the UK-Core-Observation-Group-Lab profile.
  • Added Extension UKCore-ObservationOrganizer. This extension mirrors the Observation.organizer data element introduced in FHIR R6, which indicates whether an Observation is being used to represent a test group. Updated the relevant FHIR examples to use the new extension.
  • Added an open slice to UK-Core-Observation-Lab.code to support the use of the following SNOMED CT reference sets:
    • 1853561000000109 | PaLM (Pathology and Laboratory Medicine) procedure simple reference set
    • 1853551000000106 | PaLM (Pathology and Laboratory Medicine) observable entity simple reference set
    • 999002881000000100 | Pathology Bounded Code List (PBCL) observables simple reference set
  • Created separate FHIR value sets for the SNOMED PaLM and SNOMED PBCL observable entity reference sets (these were previously combined in a single FHIR value set).
  • Added guidance for using the standard FHIR Extension valueset-reference with UK-Core-Observation-Lab.code.
  • Removed references to the UKCore-Bundle and UKCore-MessageHeader profiles and replaced them with the Bundle and MessageHeader resources from the base FHIR specification.
  • Added guidance to UKCore-Observation-Lab (Test Result) to clarify that units of measure must only be represented as text rather than using a coded representation.
  • Updated all links to the UK Core Implementation Guide to the latest version (STU3 Sequence).
  • Added the CapabilityStatements and MessageDefinitions pages (both under the FHIR Assets menu bar item).
  • Updated the Home page as follows:
    • Renamed the 'Pathology Data Products' section heading to 'SNOMED CT for Pathology Reporting' and updated the associated content.
    • Added a section for the DAPB4101 Pathology and Laboratory Medicine Reporting Information Standard.
  • Removed the Build menu bar item which contained the 'How to Construct a Pathology Test Request Bundle' and 'How to Construct a Pathology Test Report Bundle' pages. The content from these pages has been combined into a How to Construct Bundles page and added to the Design menu bar item.
  • Updated the Full Blood Count Report example to include Observation.interpretation for out of range values.
  • Updated the Lipids Profile and HbA1c Report example to include the SNOMED CT PaLM concept for serum cholesterol/high density lipoprotein ratio result.
  • Updated the current GP practice data flows diagram and description in the Background page to include message acknowledgements.
  • Updated to use the latest NHS England FHIR Implementation Guide template.

v0.1.8 (30/08/2024)

  • Updated the following examples:
    • Full Blood Count Request - changed the data element used to carry clinical context from ServiceRequest.note to ServiceRequest.reasonCode.text
    • Full Blood Count Report - changed the data element used to carry clinical context from ServiceRequest.note to ServiceRequest.reasonCode.text
    • DiagnosticReport Snippets - added an example for extension-DiagnosticReport.note, changed DiagnosticReport.basedOn.type from "http://hl7.org/fhir/StructureDefinition/ServiceRequest" to "ServiceRequest" and added an additional instance of DiagnosticReport.category to illustrate how a laboratory department name may be carried.
    • ServiceRequest Snippets - added examples for ServiceRequest.identifier.type to illustrate the use of separate business identifiers for the laboratory service requester and laboratory service provider.
  • Added additional guidance to the Design Overview page and UKCore-Observation-Lab (Test Result) profile definition regarding the use of text for semi-quantitative and qualitative result types.
  • Added an Extensions page (under the FHIR Assets menu bar item).

v0.1.7 (21/06/2024)

  • Added two new Bundle examples, Glucose Tolerance Test Report Unstructured and Urine MC&S Report Unstructured, based on the existing structured versions of the same examples. The unstructured versions illustrate how complex reports may be represented using formatted text within a single Observation, rather than using a set of structured, coded Observations.
  • Updated the Urine MC&S Report Structured example to include a new overarching test group Observation, with the following code (taken from the SNOMED CT PaLM procedure reference set):
    • 401324008 | Urinary microscopy, culture and sensitivities
  • Added the following new Bundle examples:
  • Updated UKCore-Observation-Lab.code in the examples to use content from the SNOMED CT PBCL reference set alongside equivalent content from the SNOMED CT PaLM content reference set.
  • Updated UKCore-Practitioner.identifier in the Bundle examples with a test GMC code for the requesting practitioner.

v0.1.6 (17/05/2024)

  • Updated the Additional Guidance section in each of the Profiles to align with the content and format used in the UK Core Implementation Guide (STU2 Sequence).
  • Added links from each of the Profiles to the examples in the Examples Index, and also added links to the examples in the UK Core Implementation Guide. Included a new Table view for all examples.
  • Added a new Data Mapping page (under the Design menu bar item). This provides a set of data mappings between the FHIR profiles that are referenced by this implementation guide and the PMIP EDIFACT (NHS003) messaging specification.
  • Updated the CodeSystems and ValueSets pages (under the FHIR Assets menu bar item).

v0.1.5 (01/03/2024)

  • Updated the examples in the Examples Index to correct various validation errors.
  • Updated the Design Overview page to include a description of how various types of test result (i.e. quantitative, semi-quantitative, qualitative, quantitative with an interpretation, narrative) should be represented and added corresponding Observation examples to the Examples Index.
  • Included changes to the pathology related profiles that were made as part of the HL7 UK STU2 Ballot process.

v0.1.4 (29/12/2023)

v0.1.3 (08/12/2023)

  • Added a new Background page (under the Design menu bar item). This incorporates content from the previous version of the Design Overview page, with additional material describing GP practice pathology data flows.
  • Updated the Design Overview page (under the Design menu bar item). This now contains additional content, including a summary of the FHIR design approach that has been adopted as part of this implementation guide and the use of SNOMED CT.
  • Updated references to the PaLM and PBCL SNOMED CT reference sets throughout the implementation guide.

v0.1.2 (30/10/2023)

  • Removed all FHIR STU3 related content, in line with the recent announcement from the NHS England Interoperability Standards Team that CareConnect has been deprecated and all development on the CareConnect FHIR STU3 assets has ceased.
  • Updated the examples in the Examples Index to include a populated category element for UKCore-DiagnosticReport-Lab, UKCore-Observation-Group-Lab and UKCore-Observation-Lab.
  • Updated the structure of the implementation guide to align with the latest NHS England FHIR Implementation Guide template.

v0.1.1 (04/10/2023)

  • Updated to incorporate a new set of laboratory specific FHIR R4 derived profiles, as defined in the UK Core Implementation Guide (STU2 Sequence):
    • UKCore-DiagnosticReport-Lab
    • UKCore-Observation-Group-Lab
    • UKCore-Observation-Lab
    • UKCore-ServiceRequest-Lab
    • Note: UKCore-Specimen does not have a pathology specific derived profile.
  • Updated to use the NHS England FHIR Implementation Guide template.

v0.1.0 (17/04/2023)

  • Initial draft.
