Extension certainty - Detailed Descriptions

Patient Care Work Group Maturity Level: 1InformativeUse Context: Any

Detailed Descriptions for the elements in the extension.

Extension
Element IdExtension
Definition

Statement about the degree of clinical certainty that the specific substance was the cause of the manifestation in this reaction event.

Cardinality0..1
Comments

When certainty is missing, it means no information exists (although it could be in narrative). By contrast, the unknown code is used when there is an explicit assertion that certainty is not known, such as when a patient eats a meal and it is unknown which food caused the reaction.
