Clinic Description Annotator for FHIR and SPARC

Clinical Description Annotator

Annotator for annotating measurement results, workflows, workflow tools, models, and workflow tool process datasets in SPARC SDS datasets to the data format required for digitaltwins-on-fhir.

Usage

Annotate the measurements data for SPARC SDS dataset

• Add measurement for one patient

from fhir_cda import Annotator
from fhir_cda.ehr import ObservationMeasurement, ObservationValue, Quantity

annotator = Annotator("./dataset/dataset-sparc").measurements()

m = ObservationMeasurement(
    value=ObservationValue(
        value_quantity=Quantity(
            value=30,
            unit="year",
            code="a")),
    code="30525-0")

annotator.add_measurements("sub-001", m).save()

• Add measurements for one patient

m1 = ObservationMeasurement(
    value=ObservationValue(
        value_quantity=Quantity(
            value=0.15,
            unit="cm",
            code="cm")),
    code="21889-1")
m2 = ObservationMeasurement(
    value=ObservationValue(
        value_quantity=Quantity(
            value=0.15,
            unit="cm",
            code="cm",
            system="http://unitsofmeasure.org")),
    code="21889-1",
    code_system="http://loinc.org",
    display="Size Tumor")
annotator.add_measurements("sub-001", [m1, m2]).save()

• Add measurement for multiple patients

m = ObservationMeasurement(
    value=ObservationValue(value_string="Female"),
    code="99502-7",
    display="Recorded sex or gender",
    code_system="http://loinc.org")
annotator.add_measurements(["sub-001", "sub-002"], m).save()

• A measurements for multiple patients

m1 = ObservationMeasurement(
    value=ObservationValue(value_string="Female"),
    code="99502-7",
    display="Recorded sex or gender",
    code_system="http://loinc.org")
m2 = ObservationMeasurement(
    value=ObservationValue(
        value_quantity=Quantity(
            value=0.15,
            unit="cm",
            code="cm",
            system="http://unitsofmeasure.org")),
    code="21889-1",
    code_system="http://loinc.org",
    display="Size Tumor")
annotator.add_measurements(["sub-001", "sub-002"], [m1, m2])
annotator.save()

• Add DocumentReference measurements

from fhir_cda.ehr import DocumentReferenceMeasurement
m2 = DocumentReferenceMeasurement(
    url="https://example.org/files/df0c4efd-69a6-428a-ba70-786caecfadfb.obj",
    content_type="model/obj",
    title="Breast Surface Mesh")
annotator.add_measurements(["sub-001"], [m2]).save()

• Automated generating ImagingStudy Measurement for all patients by scan dataset

annotator.automated_generating_imaging_study_measurement_by_scan_dataset()

• Add ImagingStudy measurements manually
  • Note: If we add it manually, we'll need to add the ImagingStudy measurement for each patient one by one. Alternatively, we can use a loop to automate the process.

from fhir_cda.ehr import ImagingStudyMeasurement
from fhir_cda.utils import check_first_file_extension
from pathlib import Path

p1 = Path("./dataset/dataset-sparc/primary/sub-001")
p1_sams = [x for x in p1.iterdir() if x.is_dir()]
p1_dcm_sams = [sam for sam in p1_sams if check_first_file_extension(sam) == "dcm"]
m4 = ImagingStudyMeasurement(uuid="",
                             sample_paths=p1_dcm_sams,
                             endpoint_url="",
                             description="dcm")
annotator.add_measurements(["sub-001"], [m4])

• Notice: The default value for unit system and code system are:

unit_system = "http://unitsofmeasure.org"
code_system = "http://loinc.org"

Design Decisions

• ImagingStudy Instances are not include at this stage, because but can be added it if required.
