Clinical Document Architecture
2.0.1-sd - release

Clinical Document Architecture, published by Health Level 7. This guide is not an authorized publication; it is the continuous build for version 2.0.1-sd built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/CDA-core-sd/ and changes regularly. See the Directory of published versions

Logical Model: Act (CDA Class)

Official URL: http://hl7.org/cda/stds/core/StructureDefinition/Act Version: 2.0.1-sd
Active as of 2025-10-02 Computable Name: Act

A derivative of the RIM Act class, to be used when the other more specific classes aren't appropriate.

Act.negationInd, when set to "true", is a positive assertion that the Act as a whole is negated. Some properties such as Act.id, Act.moodCode, and the participations are not affected. These properties always have the same meaning: i.e., the author remains the author of the negative Act. An act statement with negationInd is still a statement about the specific fact described by the Act. For instance, a negated "finding of wheezing on July 1" means that the author positively denies that there was wheezing on July 1, and that he takes the same responsibility for such statement and the same requirement to have evidence for such statement than if he had not used negation.
