Scope and Usage

This profile sets minimum expectations for the Observation resource that represents numerical measurement, calculation, or setting.

Formal Views of Profile Content

Description of Profiles, Differentials, Snapshots and how the different presentations work.

This structure is derived from Observation

Summary

The profile defines the following rules:

  • Observation.code shall have a coding from the ISO/IEEE 11073 MDC Metric nomenclature if there is an appropriate code available. Depending on the type of measurement, the Vital Signs profiles may require an additional LOINC code.
  • Observation.subject shall be present and refer to a Patient resource or MDS Device resource.
  • Either Observation.valueQuantity or Observation.valueRatio or, if there is no value, Observation.dataAbsentReason shall be present. Values shall have a UCUM unit code.
  • Observation.interpretation coding includes measurement status.
  • Observation.device shall be present and refer to the Numeric DeviceMetric resource which this observation belongs to.

Mandatory: 2 elements (3 nested mandatory elements)
Must-Support: 12 elements
Fixed Value: 3 elements
