description | The US Core Patient Profile inherits from the FHIR [Patient](https://hl7.org/fhir/R4/patient.html) resource; refer to it for scope and usage definitions. This profile meets the requirements of the [U.S. Core Data for Interoperability (USCDI)](https://www.healthit.gov/isp/united-states-core-data-interoperability-uscdi) *Patient Demographics/Information* Data Class. It sets minimum expectations for the Patient resource to record, search, and fetch basic demographics and other administrative information about an individual patient. It specifies which core elements, extensions, vocabularies, and value sets **SHALL** be present and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption. | (Base Level) The goal of this profile is to describe a data-minimized version of Patient used to convey information about the patient for Identity Matching utilizing the $idi-match operation. Only requires that 'some valuable data' be populated within the Patient resource and utilizes no weighting of element values. | Values Differ
