Resource Profile: IHE SDC/eCP on FHIR Observation

This Observation Profile describes how to capture Question/Answer Pairs from IHE SDC. If the question is Multiselect multiple Observations with the same Question Code should be created. A section should also be represented as a grouping Observation. If the question has a follow up text or number entry field e.g. Other (Specify) the information from the textbox should be stored in the Observation.component.value, and the Observation.component.code should repeat the Observation.value as the sub-question.

Usage:

• Derived from this Resource Profile: US Pathology Grouper Observation
• Refer to this Resource Profile: IHE SDC/eCP on FHIR Observation
• Examples for this Resource Profile: Observation/observation-TNM-descriptors, Observation/observation-clinical-history, Observation/observation-distant-metastasis, Observation/observation-functional-status...

Constraints

Id	Grade	Path(s)	Details	Requirements
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-4	error	Observation	If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated : contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()
dom-5	error	Observation	If a resource is contained in another resource, it SHALL NOT have a security label : contained.meta.security.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-3	error	Observation.referenceRange	Must have at least a low or a high or text : low.exists() or high.exists() or text.exists()
obs-6	error	Observation	dataAbsentReason SHALL only be present if Observation.value[x] is not present : dataAbsentReason.empty() or value.empty()
obs-7	error	Observation	If Observation.code is the same as an Observation.component.code then the value element associated with the code SHALL NOT be present : value.empty() or component.code.where(coding.intersect(%resource.code.coding).exists()).empty()
