This table captures the risk of adverse reactions to specific substances and helps healthcare providers manage patient safety effectively. Show full answer Show less ## Key Features * **Patient Associations:** Tracks any allergy or intolerance linked to a patient. * **Data Points:** Includes critical information such as allergy code, type, category, criticality, clinical status, and relevant dates. * **Role Requirement:** Configuration of the table requires the snhcls.admin role. * **Auto-Numbering:** The system auto-generates an identifier for each allergy or intolerance entry, beginning from ALLR00001001, with the ability to customize the format. ## Key Outcomes By utilizing the Allergy Intolerance table, ServiceNow customers can efficiently manage and document allergies and intolerances, which enhances patient care and safety. The structured data supports clinical decision-making and compliance with healthcare standards, ensuring that all relevant information is accessible and up to date. 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.{#hcls-allergy-intolerance__allergy-table-sd} ## Key features {#hcls-allergy-intolerance__section_r3h_m3k_4pb} * Stores any allergy or intolerance associated with a patient. * Includes the allergy code, type, category, criticality, clinical status, date recorded, and date of onset. {#hcls-allergy-intolerance__ul_s3h_m3k_4pb} Role required to configure the table: sn_hcls.admin.

The following categories are available by default: * Biological * Environment * Food * Medication {#hcls-allergy-intolerance__ul_qdf_jwm_ppb} For more information about the available categories, see [allergy intolerance categories](https://www.hl7.org/fhir/valueset-allergy-intolerance-category.html) defined in the FHIR specifications. | | Clinical status | Choice list | Status of the allergy or intolerance under clinical trial. The following statuses are available by default: * Active * Inactive * Resolved {#hcls-allergy-intolerance__ul_v5y_t1l_ppb} For more information about the available statuses, see [allergy intolerance clinical statuses](https://www.hl7.org/fhir/valueset-allergyintolerance-clinical.html) defined in the FHIR specifications. | | Criticality | Choice list | Estimate of the potential clinical harm or seriousness of a reaction to an identified substance. The following types are available by default: * High * Low * Unable to access {#hcls-allergy-intolerance__ul_tr2_gbl_ppb} For more information about the available types, see [allergy intolerance criticality types](https://www.hl7.org/fhir/valueset-allergy-intolerance-criticality.html) 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. For more information, see [Add auto-numbering records in a table](https://www.servicenow.com/docs/access?context=t_AutoNumberingRecordsInATable&version=australia&pubname=australia-platform-administration&ft:locale=en-US). | | Patient | Reference | Patient who has the allergy or intolerance. | | Source | Reference | Source system details of an external healthcare system in a ServiceNow instance. | | Type | Choice list | Underlying physiological mechanism for a reaction risk. The following types are available by default: * Allergy * Intolerance {#hcls-allergy-intolerance__ul_eyl_dxm_ppb} For more information about the available types, see [allergy intolerance types](https://www.hl7.org/fhir/valueset-allergy-intolerance-type.html) defined in the FHIR specifications. | | Verification status | Choice list | Assertion about certainty associated with a propensity or potential risk of a reaction to the identified substance. The following statuses are available by default: * Confirmed * Entered in error * Refuted * Unconfirmed {#hcls-allergy-intolerance__ul_k4z_kbl_ppb} For more information about the available statuses, see [allergy intolerance verification statuses](https://www.hl7.org/fhir/valueset-allergyintolerance-verification.html) defined in the FHIR specifications. | [Table 1.
