R5: ClinicalUseDefinition.undesirableEffect (new:BackboneElement)


Optional Extension Element - found in all resources.

ShortR5: A possible negative outcome from the use of this treatment (new)Optional Extensions Element
Comments

Element ClinicalUseDefinition.undesirableEffect is not mapped to FHIR R4, since FHIR R5 ClinicalUseDefinition is not mapped. Element ClinicalUseDefinition.undesirableEffect has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).

Definition

An Extension


May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
