The free-text or structured narrative explaining the nature of a patient's adverse reaction, including reaction type, severity, and causative agent. Stored in EHR allergy modules and transmitted via HL7 v2 AL1 segments or FHIR AllergyIntolerance.note fields for clinical decision support and care coordination.

allergy detailalrg_dtl

Granular clinical information associated with a patient's adverse reaction record, including specific reaction manifestations, onset patterns, and severity classifications. Populated in EHR systems such as Epic and Cerner, and referenced by pharmacy benefit management platforms during drug utilization review and clinical alerts processing.

allergy discharge datealrg_dsch_dt

The date a patient was released from an inpatient facility as recorded in the context of an adverse reaction history event. Used in institutional EHR and claims data systems to correlate allergy-related inpatient episodes with discharge dispositions, supporting utilization review and post-discharge care planning workflows.

allergy due datealrg_due_dt

The payment deadline date for a adverse reaction history. Used to track temporal information related to allergy due date. This field is commonly used in electronic health records (EHR), healthcare information systems (HIS), and clinical data warehouses for allergy management and reporting.

The time span length for a adverse reaction history. Used in healthcare data management and clinical workflows. This field is commonly used in electronic health records (EHR), healthcare information systems (HIS), and clinical data warehouses for allergy management and reporting.

allergy effective datealrg_eff_dt

The date on which a documented adverse reaction or allergy record becomes clinically active in the patient's medical history. Used in EHR allergy modules and interoperability systems to determine the valid start of an allergy record for clinical decision support, drug-allergy checking, and longitudinal patient record management.

allergy emailalrg_eml

The electronic mail address associated with a patient or provider contact record within an adverse reaction or allergy history entry. Captured in EHR patient demographic modules and care coordination platforms, this field supports patient communication workflows and allergy-related notification routing in healthcare data integration systems.
