Volume 3 - Content Profiles

There are four different categories of Audit Events in the context of the EPR:

  1. Document management (e.g. a document has been uploaded to the EPR of a patient or a list of document metadata has been retrieved)
  2. Policy management (e.g. a patient has given a healthcare professional access rights to his EPR)
  3. Access Patient Audit Record Repository by a patient or representative (a patient viewed the Audit Trail for the Audit Record Repository)
  4. Notification of the patient about the entry of healthcare professionals into a group

Each category is described as a content profile. These content profiles are based on the AuditEvent Resource, http://hl7.org/fhir/R4/auditevent.html.

The AuditEvent Resource has mapping rules to the DICOM audit message format, which allows to map to ATNA.
