AllergyIntolerance

The following topic describes information for the AllergyIntolerance resource.

To interact with the REST endpoints in the AllergyIntolerance resource, see AllergyIntolerance.

Overview

The AllergyIntolerance resource provides the clinical assessment of a patient's allergy when exposed to a specific substance or class of substance, including information about the adverse reaction. Soarian Clinicals does not differentiate between an allergy and an intolerance. The term allergy is used generically and may overlap with an intolerance. Substances include medications, foods, and environmental allergens (such as plants and animals).

Allergy negation statements for No Known Allergies (NKA), No Known Drug Allergies (NKDA), and No Known Food Allergies (NKFA) are reported using the code element. If a patient has not been asked about their allergies, these statements are conveyed by the absence of information (empty query response). Allergy negation statements for latex and contrast are not coded and are conveyed in the response with the AllergyIntolerance.code.text element as No known latex allergy (situation) or No known contrast allergy (situation).

Soarian Clinicals supports a read-only Application Programming Interface (API). This API accepts GET and POST based search and GET based read interactions. The response represents the most current information about the patient that is charted in Soarian Clinicals at the time of the query.
