Scope and usage

KLGatewayChildrenHeadCircumference is used to document childrens head circumference.

Observation.code.coding holds the valid values for the types of observations allowed. It is bound to a mandatory LOINC code: 9843-4 ‘Head Occipital-frontal circumference’, and a SNOMED CT code 363812007 ‘Head circumference (observable entity)’.

The Observation.value[x] is a valueQuantity. The unit is drawn from UCUM and is always ‘cm’.

The effective time of the observation is documented in Observation.effective[x].

Observation.category is populated to conform to international vital-sign standards. The value should always be ‘vital-signs’.

Observation.subject holds the reference to the child. Observation.encounter holds the reference to the encounter in which the observation is performed.

Notice that the status-attribute is mandatory. For normal use, just set to “final”, if data is missing or another problem has occured, follow the FHIR guidance to populate the field correctly. To indicate missing data, Observation.dataAbsentReason can be used as well.
