Gebz:FHIR bc-FetusObservation

1 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.

1.1 Profile

The entire profile can be found at: bc-FetusObservation

1.2 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.
