Summary of Allergy intolerance table

The Allergy intolerance [snhclsallergy] table in ServiceNow's Healthcare and Life Sciences data model stores clinical assessment information regarding a patient's allergy or intolerance. It captures the propensity or potential risk of an adverse reaction to specified substances or substance classes upon future exposure. This enables healthcare providers to track, manage, and assess allergy-related risks for patients within the system.

Key Features

Comprehensive allergy and intolerance data: Records include allergy codes, categories, clinical status, criticality, verification status, and dates related to onset and recording.
Detailed patient association: Each record references the patient and relevant healthcare encounters, ensuring contextual clinical data linkage.
Standardized classifications: Uses choice lists aligned with FHIR specifications for categories (e.g., Biological, Environment, Food, Medication), clinical statuses (Active, Inactive, Resolved), criticality (High, Low, Unable to assess), types (Allergy, Intolerance), and verification statuses (Confirmed, Entered in error, Refuted, Unconfirmed).
Auto-numbering support: Allergy intolerance records are assigned unique alpha-numeric identifiers (e.g., ALLR00001001) with customizable auto-numbering formats.
Role-based configuration: Requires the snhcls.admin role to configure the table and related settings.
External system integration: Supports referencing external healthcare sources and identifiers, facilitating interoperability with electronic medical records (EMRs).

Practical Implications for ServiceNow Customers

By leveraging this table, ServiceNow customers within healthcare environments can effectively document and manage allergy and intolerance data consistent with healthcare standards. This enhances patient safety by enabling accurate tracking of allergy risks, supports clinical decision-making, and ensures data interoperability with external health systems. The structured and standardized data fields help maintain data quality and compliance with healthcare regulations.

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.

The following types are available by default: High Low Unable to access For more information about the available types, see allergy intolerance criticality types defined in the FHIR specifications.
Date of onset	Date/Time	Date and time that the allergy or intolerance began.
Date recorded	Date/Time	Date the first version of the allergy or intolerance was recorded into the application.
Encounter	Reference	Healthcare event during which this allergy intolerance was asserted.
External id	String	Identifier of the record in an electronic medical record (EMR) system.
Number	String	Alpha-numeric profile identifier of the allergy intolerance. The value is auto-generated and is incremented every time you add a new allergy or intolerance to your ServiceNow instance. The initial value for the Number field is ALLR00001001. Note: To customize the number, define the auto-numbering format for the Allergy intolerance [sn_hcls_allergy] table.
