Key Features
- Captures detailed allergy or intolerance information linked to a patient, including allergy codes, types, categories, and clinical status.
- Tracks criticality levels to estimate the potential seriousness of reactions.
- Records relevant dates such as onset and when the allergy was first documented.
- Associates allergy records with healthcare encounters and external systems via references.
- Includes auto-generated alphanumeric identifiers for easy tracking and management of allergy records.
- Supports configuration by users with the snhcls.admin role for customization and integration.
Practical Use and Configuration
ServiceNow customers can utilize this table to maintain accurate and standardized allergy information aligned with FHIR specifications. Key form fields enable categorization by substance type (e.g., food, medication), clinical status (active, inactive, resolved), and verification status (confirmed, refuted, etc.), facilitating clinical decision-making and patient safety.
The auto-numbering feature allows customization of allergy record identifiers, ensuring alignment with organizational standards. Integrations with external EMR systems are supported through external ID and source references.
Benefits for ServiceNow Customers
- Enables consistent and comprehensive allergy data capture to improve patient care and risk management.
- Facilitates interoperability with external healthcare systems using standard references and codes.
- Supports clinical workflows by providing clear status and criticality indicators for allergy and intolerance records.
- Allows administrators to configure and extend allergy data management to meet organizational needs.
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.
