Data Element Information
Use Case Description(s)
Use Case Description To ensure interoperability across the healthcare ecosystem, national standardizing bodies must align. For example, if one standard body requires allergy criticality, then all standard bodies should require that same data element.
Estimate the breadth of applicability of the use case(s) for this data element Level 1
ONC Priority
  • None of the above
Maturity of Use and Technical Specifications for Data Element
Applicable Standard(s) HL7 FHIR R4 Allergy Intolerance Criticality, Rx Norm, SNOMED CT, National Drug Code (NDC)
http://hl7.org/fhir/ValueSet/allergy-intolerance-criticality
Additional Specifications HL7 FHIR R4 Allergy Intolerance Criticality
Current Use (Level 1) Captured, stored, or accessed in at least one production EHR or HIT module
Extent of exchange (Level 1) Between two production EHRs or other HIT modules using available interoperability standards
Supporting Artifacts HL7 FHIR R4
http://hl7.org/fhir/ValueSet/allergy-intolerance-criticality
Potential Challenges
Restrictions on Standardization (e.g. proprietary code) None
Restrictions on Use (e.g. licensing, user fees) None
Privacy and Security Concerns Standard HIPAA concerns.
Estimate of Overall Burden Minimal burden to implement since the data element is already being exchanged. This data element impacts patient safety to ensure clinicians understand the criticality of the patient's allergy.
Other Implementation Challenges Educational awareness for clinicians will be necessary since this field has replaced severity in clinical practice.
ONC Evaluation Details
Each submitted Data Element has been evaluated based on the following criteria. The overall Level classification is a composite of the maturity based on these individual criteria. This information can be used to identify areas that require additional work to raise the overall classification level and consideration for inclusion in future versions of USCDI
Criterion #1
Maturity - Current Standards		 Level 2 - Data element is represented by a terminology standard or SDO-balloted technical specification or implementation guide.
Criterion #2
Maturity - Current Use 		Level 1 - Data element is captured, stored, or accessed in at least one production EHR or HIT module.
Criterion #3
Maturity - Current Exchange		 Level 1 - Data element is electronically exchanged between two production EHRs or other HIT modules using available interoperability standards.
Criterion #4
Use Case(s) - Breadth of Applicability		 Level 2 - Use cases apply to most care settings or specialties.

PACIO Supports Advancement to USCDI V6

  • Data Class: Allergies and Intolerances Data Class
  • Data Element: Criticality (Level 2)
  • Recommendation: Advance Criticality data element from Level 2 to final USCDI v6.
  • Rationale: The PACIO Project Community* supports the earlier comments from CMS regarding food allergy intolerance, including the recommendation to advance the Criticality data element from Level 2 to inclusion in the final USCDI V6. The inclusion of the Criticality data element in the Allergies and Intolerances data class of USCDI V6 is a crucial for enhancing patient safety and clinical decision-making. The criticality data element is the necessary companion to the allergy or intolerance agent and the clinical manifestation, aka reaction, that have been included in the USCDI since V4. While the patient's allergy or intolerance agent and clinical manifestation (reaction) provide foundational information about what triggers a reaction and how it presents, the Criticality data element adds an essential layer by indicating the severity and potential impact of a future reaction. This allows healthcare providers to assess risks more accurately and prioritize interventions, ensuring that they can make informed decisions about prescribing medications, selecting alternative treatments, and avoiding agents that could trigger severe reactions.
