This profile defines the audit trail consumption requirements a community has to provide for a patient. The profile CH ATC defines and precises the actors and transaction [ITI-81] of the IHE IT Infrastructure Technical Framework Supplement Add RESTful Query to ATNA and defines the content of the Audit Messages. The different types of the Audit Messages are based on the requirements for Document and Policy Access management in order to achieve the Swiss regulation needs on the audit trail access by patients. These Audit Event types differ from the Audit Events which have also to be logged according to the IHE / CH:ATNA requirements.

The CH ATC profile text in the National Integration Profiles (SR816.11, Annex 5, Extension 2) is normative, this implementation guide is informative. This implementation guide is built with IG Publisher from HL7. See for more information about the Electronic Patient Record in Switzerland.

The Basic Audit Log Patterns (BALP) Implementation Guide is a Content Profile that defines some basic and reusable AuditEvent patterns. This includes basic audit log profiles for FHIR RESTful operations to be used when there is not a more specific audit event defined. A focus is enabling Privacy centric AuditEvent logs that hold well formed indication of the Patient when they are the subject of the activity being recorded in the log. Where a more specific audit event can be defined it should be derived off of these basic patterns. (built Tue, Aug 1, 2023 08:40-0500-05:00)
