Data Type Profile: SDCUsageContext - Detailed Descriptions

Page standards status: Trial-use Maturity Level: 3

Definitions for the sdc-usagecontext data type profile.

1. UsageContext
Definition

Specifies clinical/business/etc. metadata that can be used to retrieve, index and/or categorize an artifact. This metadata can either be specific to the applicable population (e.g., age category, DRG) or the specific context of care (e.g., venue, care setting, provider of care).

Control0..* This element is affected by the following invariants: ele-1

ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
sdc-uc-1: If code is gender, focus, user, venue or species, value must be CodeableConcept. If code is age, value must be Range. If code is workflow, task or program, value must be CodeableConcept or Reference (: code.system!='http://terminology.hl7.org/CodeSystem/usage-context-type' or (((code.code='gender' or code.code='focus' or code.code='user' or code.code='venue' or code.code='species') implies value.exists() and value is CodeableConcept) and (code.code='age' implies value.exists() and value is Range) and ((code.code='workflow' or code.code='task' or code.code='program') implies (value.exists() and (value is CodeableConcept or value is Reference)))))
2. UsageContext.id
Definition

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Control0..1
Typestring
3. UsageContext.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

9. UsageContext.value[x]:valueCodeableConcept.coding
Definition

A reference to a code defined by a terminology system.

Control0..*
TypeCoding
Must Supporttrue
Requirements

Allows for alternative encodings within a code system, and translations to other code systems.

Comments

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

12. UsageContext.value[x]:valueCodeableConcept.coding.system
Definition

The identification of the code system that defines the meaning of the symbol in the code.

Control0..1
Typeuri
Must Supporttrue
Requirements

Need to be unambiguous about the source of the definition of the symbol.

Comments

The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
13. UsageContext.value[x]:valueCodeableConcept.coding.version
Definition

The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

NoteThis is a business versionId, not a resource version id (see discussion)
Control0..1
Typestring
Comments

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
14. UsageContext.value[x]:valueCodeableConcept.coding.code
Definition

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Control0..1
Typecode
Must Supporttrue
Requirements

Need to refer to a particular code in the system.

InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
15. UsageContext.value[x]:valueCodeableConcept.coding.display
Definition

A representation of the meaning of the code in the system, following the rules of the system.

Control0..1
Typestring
Requirements

Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
16. UsageContext.value[x]:valueCodeableConcept.coding.userSelected
Definition

Indicates that this coding was chosen by a user directly - e.g. off a pick list of available items (codes or displays).

Control0..1
Typeboolean
Requirements

This has been identified as a clinical safety criterium - that this exact system/code pair was chosen explicitly, rather than inferred by the system based on some rules or language processing.

Comments

Amongst a set of alternatives, a directly chosen code is the most appropriate starting point for new translations. There is some ambiguity about what exactly 'directly chosen' implies, and trading partner agreement may be needed to clarify the use of this element and its consequences more completely.

InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
17. UsageContext.value[x]:valueCodeableConcept.text
Definition

A human language representation of the concept as seen/selected/uttered by the user who entered the data and/or which represents the intended meaning of the user.

Control0..1
Typestring
Requirements

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Comments

Very often the text is the same as a displayName of one of the codings.
