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 where this observation belongs to.

Mandatory: 2 elements (3 nested mandatory elements)
Fixed Value: 3 elements
