Definitions for the allergyintolerance-substanceExposureRisk extension.
Guidance on how to interpret the contents of this table can be found here
0. Extension | |
Definition | A complex extension allowing structured capture of the exposure risk of the patient for an adverse reaction (allergy or intolerance) to the specified substance/product. |
Short | Exposure risk of adverse reaction (allergy or intolerance) to the specified substance/product |
Comments | Changed: The 'substanceExposureRisk' extension is a structured and more flexible alternative to AllergyIntolerance.code for making positive or negative allergy or intolerance statements. This extension provides the capability to make "no known allergy" (or "no risk of adverse reaction") statements regarding any coded substance/product (including cases when a pre-coordinated "no allergy to x" concept for that substance/product does not exist). If the 'substanceExposureRisk' extension is present, the AllergyIntolerance.code element SHALL be omitted. |
Control | 0..1 |
2. Extension.extension:substance | |
Slice Name | substance |
Definition | Code for a substance or pharmaceutical product that is considered to be responsible for the adverse reaction risk or is known not to have an associated risk of an adverse reaction upon exposure. |
Short | Substance (or pharmaceutical product) |
Comments | It is strongly recommended that this element be populated using a terminology, where possible. For example, some terminologies used include RxNorm, SNOMED CT, DM+D, NDFRT, UNII, and ATC. Plain text should only be used if there is no appropriate terminology available. Additional details can be specified in the text. |
