Percentage of cells with uniform intense complete membrane staining.

Quantity representing percentage of cells with uniform intense complete membrane staining.

Decimal representing a quantity with units, whose value may be bounded from above or below, as defined in FHIR.

This definition is not fully consistent with CIMI V0.0.4 (whose definition of Quantity lacks a comparator, but includes numerical precision). Complex data types that appear frequently in FHIR have not been profiled, even if CIMI defines them differently. This choice means that the breast cancer profiles use the native FHIR datatype, rather than having to substitute a CIMI profile everywhere the native type is used.

Comparator

Code for the unit of measure of the quantity.

Code representing code for the unit of measure of the quantity.

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

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.

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.

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

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

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.

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.

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.

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).

Need to refer to a particular code in the system.

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

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

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

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.

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.

Reason that a value associated with a test or other finding is missing.

CIMI Alignment: This attribute corresponds to EvaluationResultTopic.exceptionValue, but has been moved from topic to context because missing values are only relevant when they should be recorded, but are not. The value set binding extends the set of FHIR's required data absent values, with additional concepts from CIMI.

A clinical interpretation of a finding.

CIMI Alignment: The value set binding has been chosen to align with FHIR. (Note: it is not clear if Interpretation belongs in FindingTopic, rather than a context class, but that is how CIMI has modeled it.)

The usual or acceptable range for a test result.
