  1. IHE IT Audit Messaging

  2. Proposed Division of Labor • IT Profiles and Framework • Define Transport • Define Events • Define Message Structure • Define Message Vocabulary • Discipline Frameworks • Implementation guidance • Actor specific considerations • Extended descriptions of events

  3. Event oriented, not transaction oriented • Common Audit Message describes events in terms of: • The event code • The active participants • Programs, People, etc. • The objects • Records, instances, people, etc. • A very generic structure instead of event specific structures like the IHE Radiology messages.

  4. Common Audit Message • Vocabularies • Basic IETF vocabulary • DICOM vocabulary • Defines minimum reporting requirements for particular events • Defines terminology vocabulary • Temporary IT vocabulary • Address gaps in DICOM vocabulary (especially for administrative activities).

  5. Real World Activities Product Audit Capabilities Product Capabilities Site Policies Reported Events Audit Repository All Events Application Transport Application Activities System Reportable Events DICOM Audit Vocabulary IETF CAM IHE Profiled and/or IHE Recommendations Describable Events

  6. Simple Comparison • IHE Interim User Login • DICOM • Event: ID= EV(CD14,DCM,”User Authentication), EventType= “login” or “Logout” • Active Participant (Mandatory) • UserID: Identity of person logging in, Role=Login • Active Participant (Optional) • UserID: Identity of process or node that authenticated the user, Role=Authenticator

  7. Complex Comparison • Instances Transferred • DICOM Supplement 95, A.Y.6 (pg 12) • IHE Interim, Rnode and InstancesAction

  8. Vocabulary Extensions • Primary Path • Proposals to SDO (DICOM, ASTM, etc.) • Incorporation of the SDO vocabulary by IHE • Interim Path • IHE vocabulary only when necessary due to lack of an appropriate SDO activity.

  9. Vocabulary Extensions • Extension Reviews • No Synonyms. Use existing IETF or DICOM vocabulary whenever it is applicable, even in other non-DICOM situations. • No Ambiguity. Define new vocabulary for new events and concepts. • Private Vocabularies • No conflict with standard vocabularies provided there are no synonyms or ambiguous terms used.

  10. Vocabulary Extensions • If there are no synonyms or ambiguous terms, then • You can mix messages and vocabulary • An application can use whichever vocabulary applies to a particular event
