The Lean Core Patient Profile inherits from the FHIR Patient resource; refer to it for scope and usage definitions. This profile meets the requirements of the <KSA Patient demographic data set- Need further details here>. 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.
