Draft as of 2024-12-19

Definitions for the ProblemObservation logical model.

Guidance on how to interpret the contents of this table can be found here

0. Observation
Logical Container	ClinicalDocument (CDA Class)
Validation	Instance of this type are validated by templateId
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
Invariants	should-text-ref-value: SHOULD contain text/reference/@value (`text.reference.value.exists()`) should-author: SHOULD contain author (`author.exists()`)
2. Observation.templateId
Control	1..?

Slice Name	problem-obs
Control	1..1
6. Observation.templateId:problem-obs.root
Control	1..?
Pattern Value	`2.16.840.1.113883.10.20.22.4.4`
8. Observation.templateId:problem-obs.extension
Control	1..?
Pattern Value	`2024-05-01`
10. Observation.classCode

When the Problem is Social Determinant of Health Observation, the observation/value SHOULD be a SNOMED code selected from ValueSet Social Determinant of Health Conditions 2.16.840.1.113762.1.4.1196.788 DYNAMIC (CONF:4515-32951).
Comments	This value MAY contain zero or one [0..1] @code (CONF:1198-31871).
Binding	See additional binding
38. Observation.value.qualifier
Short	The observation/value and all the qualifiers together (often referred to as a post-coordinated expression) make up one concept. Qualifiers constrain the meaning of the primary code, and cannot negate it or change its meaning. Qualifiers can only be used according to well-defined rules of post-coordination and only if the underlying code system defines the use of such qualifiers or if there is a third code system that specifies how other code systems may be combined. In cases where SNOMED CT does not have a precoordinated code that would be appropriate for the problem list, concept post coordination may be used in CDA following the principles outlined in HL7 Version 3 Implementation Guide: TermInfo - Using SNOMED CT in CDA R2 Models, Release 1 using the V3 CD Data type 1 style. This is shown in the sample XML.

Short	Who and/or what the observation is about
Comments	One would expect this element to be a cardinality of 1..1. The only circumstance in which the subject can be missing is when the observation is made by a device that does not know the patient. In this case, the observation SHALL be matched to a patient through some context/channel matching technique, and at this point, the observation should be updated. The subject of an Observation may in some cases be a procedure. This supports the regulatory inspection use case where observations are captured during inspections of a procedure that is being performed (independent of any particular patient or whether patient related at all).

182. Observation.entryRelationship:age.contextConductionInd
Definition	The entryRelationship.contextConductionInd differs from the otherwise common use of this attribute in that in all other cases where this attribute is used, the value is fixed at "true", whereas here the value is defaulted to "true", and can be changed to "false" when referencing an entry in the same document. Setting the context conduction to false when referencing an entry in the same document keeps clear the fact that the referenced object retains its original context.

Definition	Relates an Observation to the ObservationRange class, where the expected range of values for a particular observation can be specified. Guidance on how to interpret the value by comparison to a normal or recommended range. Multiple reference ranges are interpreted as an "OR". In other words, to represent two distinct target populations, two `referenceRange` elements would be used.
Short	Provides guide for interpretation
Comments	Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties.

Short	The observation/value and all the qualifiers together (often referred to as a post-coordinated expression) make up one concept. Qualifiers constrain the meaning of the primary code, and cannot negate it or change its meaning. Qualifiers can only be used according to well-defined rules of post-coordination and only if the underlying code system defines the use of such qualifiers or if there is a third code system that specifies how other code systems may be combined. In cases where SNOMED CT does not have a precoordinated code that would be appropriate for the problem list, concept post coordination may be used in CDA following the principles outlined in HL7 Version 3 Implementation Guide: TermInfo - Using SNOMED CT in CDA R2 Models, Release 1 using the V3 CD Data type 1 style. This is shown in the sample XML.

482. Observation.entryRelationship:dateOfDiagnosis.contextConductionInd
Definition	The entryRelationship.contextConductionInd differs from the otherwise common use of this attribute in that in all other cases where this attribute is used, the value is fixed at "true", whereas here the value is defaulted to "true", and can be changed to "false" when referencing an entry in the same document. Setting the context conduction to false when referencing an entry in the same document keeps clear the fact that the referenced object retains its original context.
