|Data Element Information|
|Rationale for Separate Consideration||Food allergens are another substance that can cause allergies and intolerances. Medication and Drug Class are called out in USCDI V1 as specific elements, thus food allergens should be as well. Everyone consumes food and within the healthcare system, a person’s food allergies should be documented and well known so as to avoid causing unnecessary harm which can lead to increased costs of care.
Food allergies are sometimes captured with drug allergies, but are a separate allergy causing substance and should be distinct from drugs. Food allergens are transmitted to a food service software system, but medication allergies are not.
|Use Case Description(s)|
|Use Case Description||When a patient is admitted to the healthcare system, they are given a “diet order” so that they can be provided with the proper meal, often based on disease state (problems). Food substances or food allergens that cause an allergic reaction or intolerance are included with the diet order that is transmitted to a food service software system (which is often separate from the EHR) so these substances can be avoided when a patient is served their meal. Food allergies are typically collected when a patient is admitted, possibly at the same time as medication and environmental allergies.|
|Estimated number of stakeholders capturing, accessing using or exchanging||This would impact all healthcare facilities who provide meals to patients, including, but not limited to hospitals, long term care, rehabilitation facilities, and home health. Practitioners such as physicians, nurses, and dietitians would capture, access, use and exchange this data and people who work to prepare and serve meals would also use the data element. Patients who have food allergies would be impacted by the lack of capture and submission.|

|Use Case Description||Food allergy information would also be available to the patient’s providers including, but not limited to physicians, nurses, and registered dietitians, regardless of the care setting. Typically a registered dietitian would use food allergy information while counseling or educating a patient with a food allergy so the patient knows what foods should be avoided; other practitioners might do the same.
Food allergies may also be captured and displayed on patient portals.
|Estimated number of stakeholders capturing, accessing using or exchanging||This would impact any practitioner who educates patients on their food intake and any patient who has food allergies.|
|Maturity of Use and Technical Specifications for Data Element|
|Applicable Standard(s)||SNOMED CT with a value set created in VSAC (OID: 2.16.840.1.113718.104.22.1686.3)
HL7 Cross Paradigm Specification: Allergy and Intolerance Substance Value Set(s) Definition: http://www.hl7.org/implement/standards/product_brief.cfm?product_id=482 was used to create the value set
|Current Use||In limited use in production environments|
FHIR R4 NutritionOrder via AllergyIntolerance
https://www.hl7.org/fhir/nutritionorder.html and https://www.hl7.org/fhir/allergyintolerance.html
|Number of organizations/individuals with which this data element has been electronically exchanged||2-3|
HL7 Version 3 Diet and Nutrition Orders Domain Analysis Model: http://www.hl7.org/implement/standards/product_brief.cfm?product_id=289
HL7 Cross Paradigm Specification: Allergy and Intolerance Substance Value Set(s) Definition: http://www.hl7.org/implement/standards/product_brief.cfm?product_id=482
|Restrictions on Standardization (e.g. proprietary code)||Since the work has already been done to create a value set of common food allergen substances with data from multiple hospital systems, there should be no restrictions on the standardization of this data element|
|Restrictions on Use (e.g. licensing, user fees)||The value set for common dietary food substances is available for free in VSAC so there are no restrictions on the use of this data element.|
|Privacy and Security Concerns||There are no privacy and security concerns with the use and exchange of this data element|
|Estimate of Overall Burden||The burden to capture this data element may be limited as some systems may already be capturing food allergies, just not sharing the information more widely outside of a food service software system. If this information is collected by practitioners, it may be in notes versus structured fields so the burden may increase since it should be captured in structured data fields and used for its multiple purposes.|
