Key Features
- Comprehensive Allergy Data: Stores allergy or intolerance information linked to a patient, including allergy codes, clinical category, type, criticality, clinical status, and important dates such as onset and recording.
- FHIR Standards Alignment: Uses categories, statuses, and types defined by FHIR specifications, ensuring interoperability and standardization across healthcare systems.
- Role-Based Configuration: Access to configure the table requires the
snhcls.adminrole, ensuring proper governance. - Unique Identification: Each allergy or intolerance record has an auto-generated unique number (starting at ALLR00001001), with options for custom auto-numbering formats.
- Reference Fields: Links to patient records, healthcare encounters, and external healthcare systems for comprehensive clinical context.
Key Fields and Their Practical Use
- Age of onset: Tracks when the allergy or intolerance first appeared, aiding in clinical history analysis.
- Category: Classifies substances into Biological, Environment, Food, or Medication to support clinical filtering and reporting.
- Clinical status: Indicates whether the allergy or intolerance is Active, Inactive, or Resolved to guide clinical decision-making.
- Criticality: Assesses the potential severity of reactions (High, Low, Unable to access), supporting risk prioritization.
- Date fields: Capture the date/time of onset and recording for audit and timeline reconstruction.
- Verification status: Documents the certainty of the allergy assertion (Confirmed, Entered in error, Refuted, Unconfirmed), enhancing data reliability.
- Type: Differentiates between Allergy and Intolerance, clarifying the underlying physiological mechanism.
Practical Benefits for ServiceNow Customers
By utilizing the Allergy intolerance table, healthcare organizations can maintain standardized, detailed allergy and intolerance records integrated within their ServiceNow instance. This facilitates accurate clinical assessments, supports patient safety through better risk identification, and ensures compliance with healthcare data standards. The table’s references and statuses enable seamless integration with external systems and enhance data trustworthiness, empowering care teams to make informed decisions efficiently.
The Allergy intolerance [sn_hcls_allergy] table stores the information about a clinical assessment of an allergy or intolerance; a propensity, or a potential risk to an individual, to have an adverse reaction on future exposure to the specified substance, or class of substance.
Key features
- Stores any allergy or intolerance associated with a patient.
- Includes the allergy code, type, category, criticality, clinical status, date recorded, and date of onset.
Role required to configure the table: sn_hcls.admin.
