Discussion Summary

The group reviewed the DIS proposal and discussed the proposed Phase 1 scope, including DICOM and FHIR content bindings, de-identification workflow, and alignment with existing standards.

Key Discussion Points

DICOM

• DIS should leverage existing DICOM de-identification standards and profiles.
• Transactions should reference DICOM Attribute Confidentiality Profiles and image retrieval locations.
• The proposal should reuse DICOM PS3.15 confidentiality profiles and associated de-identification evidence mechanisms where possible.

FHIR

• There is currently no IHE profile for FHIR de-identification.
• The group discussed examples from the IPS de-identification handbook.
• PCC could potentially develop FHIR de-identification profiles.
• Related work includes HL7 DARTS and DAPL, which define FHIR-based privacy transformation services and privacy-safe data profiles.

Pseudonymization

• Pseudonymization was identified as a gap area.
• No existing profiles were identified to support pseudonymization.
• Pseudonymization remains outside the initial DIS Phase 1 scope.

Technical Committee Feedback

• The Technical Committee indicated that DIS should profile an existing standard.
• The committee does not want to proceed with a profile based solely on generic REST/HTTP interactions.

Next Steps

• Continue discussion at the upcoming face-to-face meeting. Face-to-Face Agenda: ITI Face-to-Face Agenda
• Invite participation from IHE Radiology (RAD).
• Further evaluate DICOM and FHIR profiling approaches for Phase 1.
