Usage Notes

Profile specific implementation guidance:

• The BodyStructure Reference extension may be suitable for use where
  • body site is not implicit in the code found in Observation.code and
  • body site information cannot be adequately captured by a single inline coded element in Observation.bodySite.
• When sending an observation that represents a study series or panel:
  • the group / panel code is sent in Observation.code
  • the overall comments are sent in Observation.note
  • the global interpretation by the producer of the study is sent in Observation.interpretation
  • individual results may be sent in Observation.component or by referencing individual observation results in Observation.hasMember
• When sending observations that group the set of results of a multi-modality procedure:
  • A multi-modality procedure observation is sent with individual component examinations in Observation.hasMember.
  • An individual component examination observation is referenced by that multi-modality procedure observation (Observation.hasMember) rather than directly at the diagnostic report level (DiagnosticReport.result).
