Healthcare FHIR R4 data schema reference

Vertex AI Search supports a subset of FHIR R4 resources. This page lists the supported FHIR resources and elements, and their Google-defined schema configurations, such as indexability, searchability, and retrievability. You can select the Custom schema option when you create the data store to edit the schema configuration at the time of data store creation or to edit the configuration after you create the data store.

Field-level specification

Vertex AI Search supports a subset of FHIR data elements within each of the supported FHIR resources. The following sections list the supported elements for all the supported FHIR resources and mention whether the elements are indexable, searchable, and retrievable under these conditions:

  • If repeated elements have an empty index or [], all instances of this element are supported. For example, in an AllergyIntolerance resource, all instances of clinicalStatus.coding[].code are supported.
  • If repeated elements have a specific index or [0], only the first instance is supported. For example, in a Composition resource only the first instance of author[0].display is supported.
  • Relative resource references are supported with the format Resource/resourceId. For example, subject.reference must have the value as Patient/034AB16.
  • Absolute references are only supported for Binary resources and with data type set to attachment. Absolute references are only supported for Cloud Storage locations that conform to the following pattern: gs://BUCKET_NAME/FILE_PATH.
  • Internal or logical references aren't supported and such reference aren't resolved.
