A patient can have an allergy to medication, food, or materials, to name a few. If you want to access a patient’s current allergies—as documented by a specific organization—you can use this API action to retrieve a list. Typically, you can use this for:
- determining appropriate medication dosages for a patient’s allergies; or
- understanding a patient’s environmental allergies (e.g., latex allergy).
You can use this API action with the Redox FHIR® API.
Your connection's system can return results with their own FHIR® or query-based API.
The following actions must be completed before attempting the steps below.
This table has notes about how to use parameters for this API action specifically, but it's not exhaustive. Refer to the AllergyIntolerance resource schema for more details.
You must include at least one identifier for the patient that's used by the EHR system you're querying. If you don't have a patient identifier, you can find one by searching for a patient with demographics.
You can refine your search by searching specifically for a patient's active, inactive, or resolved allergies).
The response contains one or more allergies for an individual patient. In a FHIR® response, you can find the total number of included medications in the total array.
It’s also possible that you receive an empty response body with no listed allergies. This doesn’t necessarily mean that the patient is allergy-free; it only means that the organization hasn’t documented any known allergies for the patient.
The returned data fields that should help inform your workflow the most are the clinicalStatus and reaction arrays.
