Overview

  • Outcomes of cancer treatment.

Profile: CancerDiseaseStatus

http://hl7.org/fhir/us/mcode/StructureDefinition-mcode-cancer-disease-status.html

  • Base FHIR Resource: Observation
  • Derived from: Observation
  • Description: A clinician’s qualitative judgement on the current trend of the cancer.
  • mCODE-specific Attribute Constraints:
    • basedOn reference is restricted to (ServiceRequest | MedicationRequest)
    • partOf reference is restricted to (MedicationAdministration | MedicationStatement | Procedure)
    • Subject is required, must support and references (Cancer Patient)
    • Focus references (Cancer Condition Parent)
    • Status is must support
    • Code is must support and is fixed to LOINC#88040-1 “Response to cancer treatment”
    • Effective[x] is must support and is restricted to dateTime and Period
    • Performer reference is restricted to (US Core Practitioner Profile)
    • Value[x] is restricted to valueCoedableConcept and is must support
    • bodySite, specimen, device, referenceRange, hasMember, and component are zeroed out
  • mCODE-specific Extensions:
    • mcode-evidence-type
  • mCODE-specific Slices: none
  • mCODE-specific ValueSets:
    • valueCodeableConcept is bound to Condition Status Trend Value Set (required)

Other Notes of Interest: 

  • This profile is meant to represent the current trend of the cancer as a whole, not the response to a specific treatment
  • The LOINC code chosen to represent this observation (88040-1) does not precisely match the meaning of the profile; however, it’s the closest available at the present time. The current LOINC code is more granular than the definition of the profile and a new LOINC code has been requested to represent cancer disease status.
  • The basedOn, partOf, performer, subject, focus, value[x], and effective[x] attributes are restricted so references that would not be logical for this profile are not allowed.
  • bodySite, specimen, device, referenceRange, hasMember, and component are zeroed out because including a data element for this attributes would not be logical for this profile.
  • The purpose of mcode-evidence-type is to signify what kind of evidence was used as input to clinical judgement. This is the S and O in SOAP.
