# ELEMENT Constrained Domain Model: AllergiesOrAdverseReactionPropensity
A constrained 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 agent2. It is not required for there to be a corresponding Allergy or Adverse Reaction Event element for each Allergy Or Adverse Reaction Propensity element4. NOTE: The LRA Discharge Summary requirement for 'newPropensityFlag' can be derived value from the date the allergy or adverse reaction was identified. It is calculated on basis of allergies recorded after admission of patient in this hospital care spell. Require Date of Admission and Date of Identification to derive whether an Allergy is a New propensity 1: NPFIT-FNT-TO-DPM-0725.06 - NPfIT Message Implementation Manual 7.2.02 2.
