bc-FetusObservation

This is a generic profile for observations related to a fetus.

Each Fetus Observation must have:

  • a reference to the fetus BodySite, only in case there is no Patient record for the unborn fetus, this is the focus of the Observation
  • a subject, either the child Patient, or the woman Patient in case there is no Patient record for the unborn fetus
  • performer should be provided if known (this may not always be the case for historical data). performer is the responsible care professional.

Profile

The entire profile can be found at: bc-FetusObservation

Pattern

This is a pattern for fetus-related Observations in Birthcare. Not for observations related to the born child. Note that the meta.profile element should at least include nl-core-observation and preferably bc-FetusObservation.

All FHIR instances which follow this pattern will be valid Fetus Observations. Other fields from the FHIR profile may be present: this description is a minimal representation.
