Definitions for oncology-BreastPathologicalLymphNodeInvolvement-model.

oncology-BreastPathologicalLymphNodeInvolvement-model
Definition

Clinical assessment of lymph nodes for presence of cancer cells in staging the N category in cancers.

oncology-BreastPathologicalLymphNodeInvolvement-model.laboratoryObservationTopic
Definition

The topic composition for laboratory observations. A specimen is required, anatomical location is excluded (since the specimen indicates the collection body site). Also includes a diagnostic service (indicating the type of laboratory), not present in general observations.

Control1..1
TypeBackboneElement
oncology-BreastPathologicalLymphNodeInvolvement-model.laboratoryObservationTopic.topicCode
Definition

The concept representing the finding or action that is the topic of the statement.

For action topics, the TopicCode represents the action being described. For findings, the TopicCode represents the 'question' or property being investigated. For evaluation result findings, the TopicCode contains a concept for an observable entity, such as systolic blood pressure. For assertion findings, the TopicCode contains a code representing the condition, allergy, or other item being asserted. In all cases, the TopicCode describes the topic independent of the context of the action or the finding.

Control1..1

oncology-BreastPathologicalLymphNodeInvolvement-model.laboratoryObservationTopic.topicCode.id

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
oncology-BreastPathologicalLymphNodeInvolvement-model.laboratoryObservationTopic.topicCode.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Control0..*
TypeExtension
Comments

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.

oncology-BreastPathologicalLymphNodeInvolvement-model.laboratoryObservationTopic.topicCode.system
Definition

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

Control1..1
Typeuri
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 de-reference to some definition that establish the system clearly and unambiguously.

Fixed Valuehttp://snomed.info/sct
oncology-BreastPathologicalLymphNodeInvolvement-model.laboratoryObservationTopic.topicCode.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.

oncology-BreastPathologicalLymphNodeInvolvement-model.laboratoryObservationTopic.topicCode.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
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.

oncology-BreastPathologicalLymphNodeInvolvement-model.laboratoryObservationTopic.findingMethod
