The Coded Enumeration Observation Profile is used when the PHD observation value is represented by one of a limited set of codes. This corresponds to the Single Event Observation class in IEEE 11073-10206 ACOM and the Simple Discrete Observation in GHS.

The MDC code of the value in this observation resource corresponds to the value attribute in these ACOM and GHS observation classes.

One example of a coded measurement would be the Glucose Monitor meal context associated with a glucose concentration measurement. The code would indicate one of fasting, preprandial, postprandial, bedtime, etc. Coded measurements are often associated with other measurements. Another example would be the type of exercise in an activity session (walk, run, swim, hike, bike, etc.). Each of these enumerated options is given by a nomenclature code.

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()
mdc-1	warning	Observation.code	A published MDC Code is preferred but private MDC codes are allowed as well. : coding.exists() and coding.where(system = 'urn:iso:std:iso:11073:10101').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()
