Clinical

Marital status of the patient associated with the allergy record, captured as part of the broader demographic profile linked to clinical documentation. Used in population health analytics and social determinants of health reporting where demographic context accompanies clinical allergy data.

Enterprise master patient index identifier linked to an allergy record, enabling consistent identification of the patient across multiple clinical systems and facilities. Used during patient matching and record consolidation to ensure allergy histories are accurately attributed within integrated health networks.

Upper threshold value associated with an allergy-related clinical measurement or dosage parameter, such as the maximum tolerated exposure level or reaction severity score ceiling. Used in clinical decision support rules to flag when an allergy-related value exceeds defined safe or reference limits.

Facility-assigned medical record number of the patient to whom an allergy record belongs. Serves as the primary patient identifier linking adverse reaction history to the clinical record within a specific healthcare facility's EHR or clinical data warehouse environment.

Middle name or initial of the patient associated with the allergy record. Used alongside first and last name fields to support accurate patient identity verification during allergy record review, reconciliation, or when resolving potential duplicate records in clinical systems.

Lower threshold value associated with an allergy-related clinical measurement or exposure parameter, such as the minimum detectable reaction threshold or lowest documented severity score. Used in clinical decision support and analytics to define the baseline boundary for allergy-related data validation.

Mobile phone number of the patient associated with the allergy record. Used to support patient outreach, allergy-related care coordination communications, and notification workflows when clinicians need to contact patients regarding updates or concerns about documented adverse reactions.

Username or system identifier of the user or process that last updated the allergy record. Captured as part of the audit trail in clinical data systems to ensure accountability and traceability of changes made to adverse reaction documentation, supporting compliance and data integrity requirements.

The date on which an existing adverse reaction or allergy record was last updated or edited within an EHR or clinical data system. Critical for audit trail compliance, data synchronization across interoperability platforms, and identifying record currency during HL7 FHIR AllergyIntolerance resource exchanges and ETL pipeline processing for downstream analytics systems.

Timestamp recording when an allergy record was most recently updated in the clinical system. Used in audit logging, data synchronization, and change tracking workflows to identify the most current version of an adverse reaction record and support regulatory compliance in clinical documentation.

The standardized or free-text label identifying a specific allergen or adverse reaction agent within a patient's clinical allergy record. Captured in EHR allergy modules using terminologies such as RxNorm, SNOMED CT, or NDF-RT, and used in PBM drug-allergy checking engines, clinical decision support systems, and interoperability data exchanges.

Free-text annotation field capturing supplemental clinical details about a patient's adverse reaction history in EHR allergy modules. Stores provider observations, reaction descriptions, or documentation caveats not captured in structured allergy fields across Epic, Cerner, and Meditech systems.

Numeric reference identifier assigned to a specific adverse reaction record within EHR allergy tracking systems such as Epic or Cerner. Used as a unique key to link allergy entries across clinical data tables, enabling deduplication and cross-system reconciliation in data warehouse pipelines.

Date on which a patient first experienced symptoms or a reaction associated with a documented allergy. Clinically significant for determining allergy duration, correlating with medication or treatment history, and supporting differential diagnosis during new patient encounters or allergy reconciliation reviews.

Blood oxygen saturation level recorded in association with an allergic reaction event, typically measured via pulse oximetry. Used to assess the severity of an acute allergic or anaphylactic response, supporting clinical triage decisions and documentation of physiological impact in the patient's allergy history.

Dollar amount reimbursed or paid in connection with a healthcare claim or encounter involving allergy-related diagnosis or treatment. Captured in claims and billing systems to track financial transactions associated with allergy management services, supporting revenue cycle reporting and cost analysis.

Date on which payment was processed for a healthcare claim or service associated with allergy diagnosis or treatment. Used in revenue cycle management and claims adjudication tracking to monitor reimbursement timelines and reconcile financial records tied to allergy-related clinical encounters.

Hierarchical reference linking a specific adverse reaction record to its superior classification or parent allergy category within EHR allergy ontology structures. Used in Epic and Cerner to associate drug-specific allergies to broader allergen classes, supporting clinical decision support rule evaluation.

Ratio value expressing a proportional measure related to an adverse reaction record, such as cross-reactivity probability or population prevalence of a specific allergen. Used in clinical analytics and EHR-integrated decision support tools to assess relative allergy risk across patient populations.

Time span duration defining the active or observed window of a patient's adverse reaction history in EHR and claims systems. Captures the interval between allergy onset and resolution or documentation, supporting longitudinal patient safety analysis and medication contraindication logic in PBM platforms.
