Scope and usage

KLGatewayChildrenHeadCircumference is used to document children’s 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 head circumference should be given as a decimal point with one precision.

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 occurred, follow the FHIR guidance to populate the field correctly. To indicate missing data, Observation.dataAbsentReason is used. Observation.dataAbsentReason is mandatory if no value is given. The value ‘unknown’ can always be used. It is also possible to use one of the other values in the ValueSet defined by the FHIR standard, if more details are nedded locally.

Constraints

Id	Grade	Path(s)	Details	Requirements
dk-core-observation-mandatory-units	error	Observation	If value is specified then unit and/or code must be specified : value.ofType(Quantity).value.exists() implies value.ofType(Quantity).unit.exists() or value.ofType(Quantity).code.exists()
dom-2	error	Observation	If the resource is contained in another resource, it SHALL NOT contain nested Resources : contained.contained.empty()
dom-3	error	Observation	If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource : contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()

dom-6	best practice	Observation	A resource should have narrative for robust management : text.`div`.exists()
ele-1	error	**ALL** elements	All FHIR elements must have a @value or children : hasValue() or (children().count() > id.count())
ext-1	error	**ALL** extensions	Must have either extensions or value[x], not both : extension.exists() != value.exists()
obs-1	error	Observation	If value is given as a decimal point number with more than one precision, an error is returned : value.ofType(Quantity).value.toString().matches('^[0-9]*\u002e?[0-9]$')
obs-2	error	Observation	If the value is not given, then explain why using dataAbsentReason : value.empty() implies dataAbsentReason.exists()
obs-3	error	Observation.referenceRange	Must have at least a low or a high or text : low.exists() or high.exists() or text.exists()
