  title: Medplum Clinical Data Query
  summary: Locate a patient by name, read the Patient resource, then pull that patient's Observations.
  description: >-
    A US Core clinical-data read flow against the Medplum FHIR R4 backend. A
    patient is located by name through a type-level search, read by id, and then
    that patient's Observations (US Core vital signs and laboratory results) are
    retrieved by patient reference. This follows the FHIR RESTful API search and
    read interactions used to assemble a patient's clinical summary. Every step
    inlines its request so the flow is self-contained.
