Clinical Document Architecture with Australian Schema
1.0.1 - active
Clinical Document Architecture with Australian Schema - Local Development build (v1.0.1) built by the FHIR (HL7® FHIR® Standard) Build Tools. See the Directory of published versions
| Official URL: http://hl7.org/cda/stds/core/StructureDefinition/Authenticator | Version: 1.0.1 | |||
| Active as of 2025-10-10 | Maturity Level: 1 | Responsible: HL7 | Computable Name: Authenticator | |
Represents a participant who has attested to the accuracy of the document, but who does not have privileges to legally authenticate the document. An example would be a resident physician who sees a patient and dictates a note, then later signs it. A clinical document can have zero to many authenticators. While electronic signatures are not captured in a CDA document, both authentication and legal authentication require that a document has been signed manually or electronically by the responsible individual. An authenticator has a required authenticator.time indicating the time of authentication, and a required authenticator.signatureCode, indicating that a signature has been obtained and is on file.
