Return to Orders & Observations Work Group

Return to Ordering Service Project Page

Return to Catalog Project Page


  • Substantive content freeze : August 10, 2018
  • Final Content freeze:
  • Ballot opens: August 24, 2018
  • Ballot closes: September 24, 2018

To Do post September Connectathon

  • ObservationDefinition:
    • Change datatype of the last 4 elements (validCodedValueSet, normalCodedValueSet, ...) from uri to Reference(ValueSet) -> RT 18995 PENDING PULL REQUEST
    • Clarify definition of qualifiedInterval ("Qualified range for continuous and ordinal observation results") -> RT 17429 PENDING PULL REQUEST (changed mapping from OM-2 to OM2-6)
  • CatalogEntry
    • Complement V2 mappings to the MFE segment -> RT 18996
    • Complement the description of classification to include categories of services and specialties (mapped to OM1-55 in V2) -> RT 18997
  • SpecimenDefinition:
    • change patientPreparation from string 0..1 to CodeableConcept 0..*. An example value set is: < 703763000 |Precondition value (qualifier value)| from SNOMED CT. Multiple pre-conditions or preparations can be specified, hence the cardinalities 0..*. In case there is no coded concept, the text element of CodeableConcept can be used. --> RT 19419
    • Correct value set of container.type to: < 706041008 |Device for body fluid and tissue collection/transfer/processing (physical object)| SNOMED CT --> RT 19422
    • Provide value set for container.material (glass, plastic, metal ... see Specimen DAM) --> RT 19425
    • Provide value set for collection (binding strength Example) --> RT 19426
    • Sometimes, the minimum volume may appear as a textual instruction. Therefore change minimumVolume from SimpleQuantity to a choice {SimpleQuantity, string} --> RT 19423
    • Challenge the usefulness of isDerived boolean element. In V2 OM4-2 “Derived specimen” uses table 0170 to specify whether the specimen is parent (e.g. blood culture) or child (e.g. pure colony isolate). Do we really need this element in SpecimenDefinition?
  • Coverage on examples: François provided for SpecimenDefinition and ObservationDefinition. Needed for other kinds of catalogs (medications, devices)
  • we should discuss Human Services use cases - look at our example use cases --> NEED TO ASSIGN TO SOMEONE
  • Profile on ActivityDefinition (NEED TO ASSIGN TO SOMEONE AFTER SEPT) --> François

To Do for September Connectathon

  • rename EntryDefinition to CatalogEntry --> DONE by Claude
  • Add scope and boundary text to resource -- DONE by Claude
  • Relationships from Activity Definition to SpecimenDefinition and ObservationDefinition --> DONE by Bryn
  • Tracker items from ballot - François prepared proposed resolutions for block vote. --> DONE
  • review value set bindings and definitions (François to do) --> DONE, review the proposals in the Post September Connectathon section above.
  • review relationship types in Catalog Entry (François to do): remove has-input, has-output and uses from the list --> DONE
  • ObservationDefinition cleanup:
    • Replace Coding by CodeableConcept on category and code --> DONE
    • Add element identifier (discovered as useful for Quest, and probably to most labs for internal identifier) --> DONE
    • I think element permittedDatatype should be of type code, with fhir value-set {quantity, time, string, CodeableConcept, ...etc) (Waiting to get core value set reference from Lorraine) --> DONE
    • Correct value set binding of qualifiedInterval.category: This is not a category of observation. An example value set would be: {"reference", "critical", "absolute"} --> DONE
    • Fix definitions for qualifiedInterval.category and qualifiedInterval.type (Actually, review all definitions for clarity and completeness) (FRANCOIS) --> DONE, see left over in section "Post September Connectathon" above.
    • qualifiedInterval.range: Correct the description from "Low bound of reference range, if relevant" to "range of the interval", also changed long description --> DONE
  • SpecimenDefinition: Apply resolutions of trackers listed here --> DONE
  • Connectathon proposal
    • François to flesh out use cases with Quest --> DONE
  • Claude to re-set up to add to build --> DONE

Done Items (June)

  • EntryDefinition: Rename purpose (1..1, CodeableConcept) to orderable (1..1, boolean) ---> Done!
  • EntryDefinition.status: Change datatype from CodeableConcept to code, change cardinality to 1..1, and assign FHIR value set PublicationStatus(required), (values: draft | active | retired | unknown). ---> Done!
  • EntryDefinition.relatedEntry.relationType: Change datatype from CodeableConcept to code, and define FHIR value set (required) with these values:
    • has-input: the related entry represents an item to be provided as input to the current item
    • has-output: the related entry represents an item produced as out put of the current item
    • uses: the related entry represents an item (product or material or substance) used by the current item
    • triggers: the related entry represents an activity that may be triggered by the current item
    • is-replaced-by: the related entry represents an item that replaces the current retired item

---> Done! Thanks Jose!

To Do Items for June

  • ObservationDefinition: various corrections
    • Correct datatype of elements category and code: from Coding to CodeableConcept
    • bind category to value set (preferred)
    • Correct datatype of element permittedDataType from Coding to code, with the binding to the FHIR value set {Quantity, CodeableConcept, string, boolean, integer, Range, Ratio, SampledData, time, dateTime, Period} (required)
    • Correct the definition of ObservationDefinition.qualifiedInterval from "Reference range for ordinal and continuous observations." to "Reference range for ordinal and quantity measurement observations."

EntryDefinition.type: Assign value set. The content of type represents the type of resource referenced by referencedItem (Medication, Device, Observation, ActivityDefinition, ...) How can we enforce that? [NOTE: WE DECIDED TO DEFER THIS UNTIL WE HAVE A CONCRETE USE CASE THAT WARRANT ITS USE.]

  • ActivityDefinition timingTiming (Timing) - confirm ability to carry a performance schedule as in eDos ---> Done!
    • an example of a performance schedule is "every Monday & Wednesday"
    • Yes, this is confirmed. The datatype Timing supports quite complex performance schedules, if needed.

Other to dos

  • Review all value sets and value set bindings
    • Add Knowledge Artifact and Order Set to the value set for type
    • review relationshipType value set - also look at similar one from Task
  • Review element definitions
  • Add search parameters to each resource - see connectathon report for suggestions for EntryDefinition
  • Prepare design summary in preparation for meeting with Lloyd
  • Add examples from connectathon to build
  • Review and prepare dispositions for comments from January ballot
