Resource Profile: AllergyIntolerance - Emergency Allergy or Intolerance (v1, permissive)

Official URL: https://fhir.dha.go.ke/ems/StructureDefinition/em-allergy-intolerance-v1 Version: 1.0.0
Active as of 2026-10-02 Computable Name: EMAllergyIntoleranceV1

A looser variant of EMAllergyIntolerance for sources that capture allergy history as free text during initial intake (e.g. "Penicillin allergy", manifestation "moderate") rather than fully coded clinicalStatus, verificationStatus, and criticality. Use EMAllergyIntolerance instead once a source can supply those fields.
