reaction revisionrxn_rev

Tracks the version or iteration number of an adverse reaction record that has been updated or amended since initial documentation. Used in clinical data management to maintain an audit trail of changes to allergy and adverse event records, supporting data integrity and regulatory compliance requirements.

reaction riskrxn_rsk

Captures the assessed danger level or probability of recurrence associated with an adverse reaction or allergic event, informing future prescribing and treatment decisions. Used in clinical decision support and allergy management systems to stratify patient safety risk and trigger appropriate contraindication alerts.

reaction routerxn_rte

Documents the route of exposure or administration of the substance that triggered an adverse reaction, such as oral, intravenous, topical, or inhalation. Used in allergy and adverse drug reaction tracking to identify exposure pathways, support contraindication logic, and guide safer alternative treatment selection.

reaction scheduled daterxn_sched_dt

Records the planned calendar date for a clinical activity related to an adverse reaction event, such as a follow-up allergy assessment, challenge test, or desensitization procedure appointment. Used in care coordination and adverse event management workflows to track planned clinical interventions.

reaction scheduled timerxn_sched_tm

Records the planned clock time for a clinical activity associated with an adverse reaction event, such as a scheduled allergy follow-up, desensitization session, or reaction monitoring appointment. Used alongside the scheduled date in care coordination systems to ensure timely clinical intervention and resource allocation.

reaction scorerxn_scr

A calculated numeric rating that quantifies the severity or intensity of a documented physiological response, such as an adverse drug reaction or allergic event. Used in clinical documentation to standardize assessment and support treatment decision-making across care episodes.

reaction sequencerxn_seq

A numeric ordering value that identifies the position of a specific physiological response within a series of documented reactions for a patient encounter or allergy record. Enables proper sequencing and retrieval of multiple reaction events in clinical data systems.

reaction service daterxn_svc_dt

The calendar date on which clinical care or evaluation was delivered in response to a documented physiological reaction, such as an adverse event or allergic episode. Used to establish the timeline of reaction-related treatment within clinical and claims records.

reaction severityrxn_sev

A coded or descriptive classification indicating the clinical seriousness of a documented physiological response, ranging from mild to life-threatening. Used in adverse event reporting, allergy documentation, and pharmacovigilance workflows to guide treatment urgency and patient safety protocols.

reaction sexrxn_sex

The biological sex of the patient associated with a documented physiological reaction or adverse event record. Used in pharmacovigilance, adverse drug reaction reporting, and clinical research to analyze sex-based differences in reaction occurrence, severity, and outcomes.

reaction sourcerxn_src

Identifies the originating system, reporter, or data feed from which a physiological reaction record was received or generated, such as an EHR, pharmacy system, or adverse event registry. Supports data lineage tracking and reconciliation across integrated clinical platforms.

reaction start daterxn_start_dt

The calendar date on which a documented physiological reaction or adverse event first manifested in the patient. Critical for establishing reaction onset timelines, correlating with medication administration records, and supporting adverse drug reaction reporting and pharmacovigilance analysis.

reaction start timerxn_start_tm

The specific time of day at which a documented physiological reaction or adverse event was first observed or reported. Used alongside reaction start date to establish precise onset timing, which is critical in acute care settings and adverse event causality assessments.

reaction staterxn_st

The U.S. state or territory associated with the geographic location where a physiological reaction was documented or reported. Used in public health surveillance, adverse event reporting systems, and population health analytics to identify regional patterns in reaction incidence.

reaction statusrxn_sts

A coded value representing the current clinical state of a documented physiological reaction, such as active, resolved, or recurring. Used in allergy and adverse event tracking to reflect the ongoing clinical relevance of the reaction and inform treatment planning.

reaction street addressrxn_st_addr

The physical street address associated with the location where a physiological reaction was reported or treated, such as a clinic, hospital, or patient residence. Used in adverse event reporting and public health tracking to establish geographic context for the reaction event.

reaction strengthrxn_str

The concentration or potency of the substance, typically a drug or allergen, associated with triggering a documented physiological reaction. Used in adverse drug reaction analysis and allergy documentation to correlate dose levels with reaction severity and inform future prescribing decisions.

reaction subtotalrxn_subtot

A partial aggregated value representing a subset of costs, events, or counts associated with documented physiological reactions within a defined grouping or reporting period. Used in clinical analytics and healthcare financial reporting to support hierarchical summarization of reaction-related data.

reaction system identifierrxn_sys_id

A unique system-generated identifier assigned to a documented physiological reaction record within a clinical or administrative data platform. Enables consistent cross-system tracking, deduplication, and linkage of reaction events across EHR, pharmacy, and adverse event reporting systems.

reaction targetrxn_tgt

Identifies the specific anatomical site, organ system, or biological pathway affected by a documented physiological reaction or adverse event. Used in clinical documentation and pharmacovigilance reporting to characterize the nature and mechanism of the patient's adverse response.
