HL7 FHIR Implementation Guide: Breast Cancer Data, Release 1 - US Realm (Draft for Comment 2)
This page is part of the Breast Cancer Data Logical Models and FHIR Profiles (v0.2.0: STU 1 Draft) based on FHIR R3. . For a full list of available versions, see the Directory of published versions 
The official URL for this logical model is:
http://hl7.org/fhir/us/breastcancer/StructureDefinition/oncology-DCISNuclearGrade-model
An evaluation of the size and shape of the nucleus in tumor cells and the percentage of tumor cells that are in the process of dividing or growing. Cancers with low nuclear grade grow and spread less quickly than cancers with high nuclear grade. In breast cancer, nuclear grade is typically evaluated for ductal carcinoma in situ (DCIS) only. There is currently no concept code for DCIS Nuclear Grade in LOINC, SNOMED, or NCI Metathesaurus.
This logical model was published on Fri Aug 17 00:00:00 AEST 2018 as a draft by The HL7 Cancer Interoperability Group sponsored by Clinical Interoperability Council Work Group (CIC).

| Name | Flags | Card. | Type | Description & Constraints |
|---|---|---|---|---|
  oncology-DCISNuclearGrade-model | 0..* | |||
  personOfRecord | 1..1 | Reference(BC PersonOfRecord Logical Model) | The person this entry belongs to. | |
 laboratoryObservationTopic | 1..1 | BackboneElement | The topic composition for laboratory observations. A specimen is required, anatomical location is excluded (since the specimen indicates the collection body site). Also includes a diagnostic service (indicating the type of laboratory), not present in general observations. | |
 topicCode | 1..1 | Coding | The concept representing the finding or action that is the topic of the statement. | |
| findingMethod | 0..1 | Coding | The technique used to create the finding, for example, the specific imaging technical, lab test code, or assessment vehicle. Binding: http://loinc.org/vs (preferred) | |
 details | 0..1 | string | A text note containing additional details, explanation, description, comment, or summarization. Details can discuss, support, explain changes to, or dispute information. | |
| category | 1..* | Coding | A class or division of people or things having particular shared characteristics | |
 extension | 0..* | Extension | Additional Content defined by implementations Slice: Unordered, Open by value:url | |

| display | Σ | 0..1 | string | Representation defined by the system |
 userSelected | Σ | 0..1 | boolean | If this coding was chosen directly by the user |
| breastSpecimen | 1..1 | Reference(BC BreastSpecimen Logical Model) | Specimen resulting from biopsy or excision of breast and surrounding tissue. | |
 precondition | 0..* | Coding, Reference(BC Observation Logical Model) | A description of the conditions or context of an observation, for example, under sedation, fasting or post-exercise. Body position and body site are also qualifiers, but handled separately. A qualifier cannot modify the measurement type; for example, a fasting blood sugar is still a blood sugar. | |
| diagnosticService | 0..* | Coding | The service completing the observations, e.g. biochemistry, microbiology, blood bank. | |

| observationContext | 1..1 | BackboneElement | Context for recording an evaluation result, used to indicate an evaluation has been made. | |
| contextCode | 1..1 | Coding | A code representing the ontological status of the statement, e.g., whether it exists, does not exist, is planned, etc. | |

 encounter | 0..1 | http://hl7.org/fhir/us/breastcancer/StructureDefinition/cimi-encounter-Encounter-model | A description of an interaction between a patient and healthcare provider(s) for the purpose of providing healthcare service(s) or assessing the health status of a patient. | |
| interpretation | 0..1 | Coding | A clinical interpretation of a finding (applies to both assertions and observation). Binding: Observation Interpretation Codes (extensible) | |
| findingStatus | 1..1 | code | Indicates whether the finding is preliminary, amended, final, etc. Binding: ObservationStatus (required) | |
| relevantTime | 0..1 | dateTime, http://hl7.org/fhir/us/breastcancer/StructureDefinition/shr-core-TimePeriod-model | The time or time period that the finding addresses. | |
| resultValue | 0..1 | Coding | The finding itself, such as the blood pressure value recorded. Binding: BC DCISNuclearGradeVS ValueSet (required) | |
| exceptionValue | 0..1 | Coding | Reason that a value associated with a test or other finding is missing. Binding: DataAbsentReason (extensible) | |
| deltaFlag | 0..1 | Coding | Indicator of significant change (delta) from the last or previous measurement. Binding: BC DeltaFlagVS ValueSet (required) | |
