Definitions for cimi-context-StatementContext-extension.
| Extension | |
| Definition | Compositional and reusable grouping of clinical statement attributes that provides the context for the topic of a clinical statement. The StatementContext class aligns with the SNOMED CT Situations with Explicit Context (SWEC) Concept Model. The StatementContext provides the expressivity required to specify that an act was performed or not performed or that a finding was asserted to be present or absent for the given subject of information. It also often holds provenance information relevant to the context of the clinical statement. It is important to note that by default the context applies to the conjunction of the attribute specified in the statement. For instance, if a clinical statement has a topic describing a rash on left arm and a context of 'absent', then the statement states that the subject of interest did not have a rash on the left arm but might have had one on the right arm. |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: children().count() > id.count()) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| Extension.id | |
| Definition | unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |

| Extension.extension ([CanonicalType[http://hl7.org/fhir/us/breastcancer/StructureDefinition/cimi-context-ContextCode-extension]]) | |
| Definition | A code representing the ontological status of the statement, e.g., whether it exists, does not exist, is planned, etc. Attribute aligns with the SNOMED CT Situation with Explicit Context (SWEC) Concept Model context attributes: 'Finding context (attribute)' (SCTID: 408729009) and 'Procedure context (attribute)' (SCTID: 408730004). The range allowed for this attribute shall be consistent with the SNOMED CT concept model specification for SWEC. |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Type | (Extension Type: CodeableConcept) |
| Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: children().count() > id.count()) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists()) |
| Extension.extension ([CanonicalType[http://hl7.org/fhir/us/breastcancer/StructureDefinition/cimi-encounter-Encounter-extension]]) | |
| Definition | A description of an interaction between a patient and healthcare provider(s) for the purpose of providing healthcare service(s) or assessing the health status of a patient. |
| Control | 0..* This element is affected by the following invariants: ele-1 |
| Type | (Extension Type: Reference(EncounterProfile)) |

| Extension.url | |
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Control | 1..1 |
| Type | uri |
| Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |

| Extension.value[x] | |
| Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). |
