Connectathon Jan 2021 Tentative Imaging Use Cases
- FHIRcast imaging use cases
- Coordinating with FHIRcast
- AI Imaging Results
- VNA sharing data with EMR
- EMR access to imaging study
- Comprehensive imaging SWF
- Linking between observation, diagnosticreport, documentreference and imagingstudy
- ImagingStudy reference in DiagnosticReport
Examples:
- https://wiki.hl7.org/index.php?title=201805_FHIRcast
- https://confluence.hl7.org/display/FHIR/2020-09+Situation+Awareness+for+Novel+Epidemic+Response
Scenario: Linking between observation, diagnosticreport / composition, documentreference and imagingstudy – coordinate with FHIRcast
Actors:
- EMR
- VNA / EIR / PACS
- EMR viewer
- Enterprise imaging viewer
Steps
- EMR viewer retrieves DiagnosticReport from EMR
- EMR viewer discovers associated ImagingStudy
- EMR viewer displays report and launches Enterprise Viewer w/ ImagingStudy context
- Enterprise imaging viewer displays ImagingStudy
- Option: Imaging Viewer creates observation and makes it available to EMR, which links to diagnostic report
- Option: Report creation variant of this?
Scenario: FHIR-enhanced Diagnostic Reading
- Links between ImagingStudy and other FHIR resources (ServiceRequest, Reason, etc.) provide additional relevant context to reading clinician
Actors:
- Diagnostic Viewer
- EMR
- VNA / PACS
Steps
- DV loads DICOM study
- DV loads ImagingStudy associated with the DICOM study
- DV follows links in ImagingStudy to access additional study context
- BasedOn
- Reason
- ...
Examples
- TODO – add examples of relevant information and how it would be related to the ImagingStudy
Scenario: Encoding AI results and radiology reports in FHIR
Actors
- Report creator
- EMR
- Report viewer
Steps
- Report creator creates radiology report
- Report creator extracts Observations from radiology report
- Report creator stores report in FHIR in one of
- Set of observations
- DiagnosticReport
- Composition
- Report viewer finds / presents information stored in above encodings
- Option: Report viewer handles conflicting observations?
- Filter by status
- Option: Report creator looks at existing observations before storing output
- See if existing data needs to be updated / deprecated
Scenario: AI Results (see previous workflow)
- FHIR results creator
- Follows AI result to imaging as per above scenario
- Option: Does this require linking back from FHIR result to DICOM result?
Scenario: FHIR-based SWF (not part of initial scenarios)
- Open questions:
- What resource(s) go into MWL content?
- What resource(s) are used by archive to reconcile study?
- What resource(s) are used to notify EMR of study complete
- ImagingStudy as EMR notification
- VNA creates ImagingStudy in EMR as equivalent to ORU 'study complete' message
Scenario: MHD / MHD-I (not part of initial scenarios)
Other notes:
- FHIRcast mechanism to indicate a resource has been updated
- EMR could create ImagingStudy via QIDO to VNA
- Possible MWL equivalent model
- Patient = DICOM Patient
- ServiceRequest = DICOM Requested Procedure
- Task= DICOM Requested Procedure Step
- ServiceRequest = DICOM Requested Procedure
- Patient = DICOM Patient
