Representing Negation

Goto: Clinicians on FHIR

Background

There are a number of clinical concepts (and hence clinical FHIR resources) to which negation are commonly applied. Examples include

• Allergy/Intolerance
• Observation
• Condition
• Procedure
• Medication

There does not appear to be a consistent way in applying negation to these (and other similar) resources.

PCWG, FHIR and OO agree that a consistent approach to this matter is highly desirable to ensure interoperability. These groups agree to collaborate in order to determine an agreed approach to achieve this goal.
