This ELEMENT Domain Model is included for illustrative purposes. The structure and terminology binding will be subject to change in forthcoming releases of the LRA. An ELEMENT to represent that a patient has a propensity for an allergic reaction or adverse reaction to a substance, food or drug¹. An allergy or adverse reaction propensity element is used to populate the patient's allergy and adverse reactions list. This is a list of all the substances/drugs/food that a person is at future risk of having an adverse reaction or allergy to. Ideally there should be only one entry per drug/substance/food/causative agent⁴. It is not required for there to be a corresponding Allergy or Adverse Reaction Event element for each Allergy Or Adverse Reaction Propensity element⁴. ^1: NPFIT-FNT-TO-DPM-0725.06 - NPfIT Message Implementation Manual 7.2.02 ^4: NPFIT-FNT-TO-SCG-0001.06 SCG Guidance on the Representation of Allergies and Adverse Reaction Information Using NHS Message Templates

Attributes

Name	Data type	Occurs	Description	Value Constraints
name	SC	1..1	The name, expressed as a coded value or as plain text, specifies the clinical or administrative concept to which this EHR node corresponds, as labelled in the EHR system in which it was first committed.	value Literal value(s): FINDING_OBSERVATION_ELEMENT
rc_id	II.Uuid	1..1	The globally-unique identifier by which this node in the EHR hierarchy is referenced in the EHR system to which the data were first committed. This identifier shall be retained by the EHR Recipient and re-used whenever this RECORD_COMPONENT is subsequently included in another EHR_EXTRACT.
meaning	CD.CV	1..1	A code to describe a propensity to an allergic or adverse reaction.	code Semantic expression constraint Literal expression constraint
synthesised	BL	1..1	This attribute value shall be TRUE if this RECORD_COMPONENT has been created in order to comply with this standard , but this point in the EHR hierarchy has no corresponding node in the EHR from which it was extracted.
obs_time	IVL_TS	0..1	The date and time, or interval, at which the propensity to an allergic or adverse reaction was present.
value	ANY	1..1	An ELEMENT has a single DATA_VALUE containing the value, unless this is indicated as absent by a null_flavour attribute.	nullFlavor Literal value(s): NA
