EvaluationResultTopicModel - Detailed Descriptions

Definitions for cimi-EvaluationResultTopic-model.

cimi-EvaluationResultTopic-model
Definition

The base class, independent of context, for evaluations (measurements, tests, or questions) and a value containing the result (answer).

The subject of a finding can be the entire patient, or an entity such as a location body structure, intervention, or condition. Things observed about the subject can include social and behavioral factors, subjective and objective observations, and assessments.

CIMI Alignment: 1) In CIMI V0.0.4, LaboratoryTestResult.specimen is 0.. but that cardinality makes it impossible to map to FHIR Observation, where specimen is 0..1. The cardinality of Specimen has been changed to 0..1 to enable FHIR mapping. 2) In CIMI V0.0.4, Findings (including EvaluationResult and LaboratoryTestResult) do not have related ('has-member') observations, nor components (sub-observations). These features of FHIR Observations were found to be very useful in modeling breast cancer pathology, and are included here. This represents a significant departure from the CIMI model. CompoundClinicalStatement has not been used to represent panel-like findings, because of the complexity of mapping this class to FHIR. 3) In CIMI V0.0.4, allowable datatypes for result (aka Value) include EmbeddedContent, GpsLocation, Multimedia, ParsableContent, and other types not allowed in a FHIR Observation. To make mapping feasible, the types of Value were restricted to only the allowable FHIR datatypes. 4) ExceptionValue has been moved to the RecordedContext, because it is only relevant when a value is supposed to be recorded, but is not. 5) The cardinality of FindingMethod has been changed from 0.. to 0..1 to make it possible to map to FHIR, where Observation.method is 0..1. 6) The class PhysicalEvaluationResult has been united with this class, and the body location (AnatomicalLocation) has been added to this class. This is because bodySite is part of Observation, and it cannot be profiled out of EvaluationResult and then re-included in PhysicalEvaluationResult. 7) The cardinality of AnatomicalLocation has been changed from 0..* to 0..1 to make it possible to map to FHIR, where Observation.bodySite is 0..1. 8) The attribute evaluationDate has been moved to RecordedContext, because it only applies to evaluations that have been done. 9) The attributes device and evaluationProcedure have been removed for brevity, since they are not used in the current IG.

cimi-EvaluationResultTopic-model.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.

CIMI Alignment: TopicCode is the new CIMI name for the attribute formerly called 'key' in CIMI V0.0.4.

Typehttp://hl7.org/fhir/us/breastcancer/StructureDefinition/cimi-TopicCode-model
cimi-EvaluationResultTopic-model.findingMethod
Definition

The technique used to create the finding; for example, the specific imaging technique, lab test code, or assessment vehicle.

CIMI Alignment: In CIMI V0.0.4, this attribute was called 'method'. The value set binding reflects CIMI's preference for LOINC codes.

Typehttp://hl7.org/fhir/us/breastcancer/StructureDefinition/cimi-FindingMethod-model
cimi-EvaluationResultTopic-model.interpretation
Definition

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.)

cimi-EvaluationResultTopic-model.anatomicalLocation
Definition

A location or structure in the body, including tissues, regions, cavities, and spaces; for example, right elbow, or left ventricle of the heart.

CIMI Alignment: In CIMI V0.0.4, AnatomicalLocation has no parent class. This appears to have been an oversight, and the parent should have been Entity, as modeled here.

Typehttp://hl7.org/fhir/us/breastcancer/StructureDefinition/cimi-AnatomicalLocation-model
cimi-EvaluationResultTopic-model.specimen
Definition

A specimen is a substance, physical object, or collection of objects, that the laboratory considers a single discrete, uniquely identified unit that is the subject of one or more steps in the laboratory workflow. A specimen may include multiple physical pieces as long as they are considered a single unit within the laboratory workflow. A specimen results from one to many specimen collection procedures, and may be contained in multiple specimen containers. Specimen may have one or more processing activities.

CIMI Alignment: This class has been cut down to parts relevant to the current oncology ballot. The attribute parentSpecimenIdentifier has been changed from an Identifier to a reference to a Specimen, to make it possible to map to FHIR.

cimi-EvaluationResultTopic-model.deltaFlag

Indicator of significant change (delta) from the last or previous measurement.

cimi-EvaluationResultTopic-model.precondition
Definition

A description of the conditions or context of an observation; for example, under sedation, fasting or post-exercise.

Body position and body site are also qualifiers, but handled separately. A qualifier cannot modify the measurement type; for example, a fasting blood sugar is still a blood sugar.

cimi-EvaluationResultTopic-model.evaluationComponent
Definition

A simplified, non-separable evaluation consisting of a finding code (represented by the Concept), value (or exception value), reference range, and interpretation.

The subject of the evaluation component is the same as in the parent evaluation.
