The following defining attributes are unique in the context of the 386053000 |Evaluation procedure (procedure)| subhierarchy. Many of these attributes (e.g., Component, Scale type) are used to define Observable entity concepts.  Evaluation procedures may use the attributes below in addition to those attributes allotted to the 

Concept
t71388002 |Procedure (procedure)|
 hierarchy (see Procedure Attributes Summary page).  All of the attributes for Evaluation procedure concepts should be grouped.  However, Some of the current modeling does not reflect this guidance, and examples used on this page are inconsistent with current guidance.  The future of this hierarchy in relation to the observable entity hierarchy is under review.  See 'Observable Entity vs. Evaluation Procedure' at at Observable Entity.

Component

Component refers to what is being observed or measured by a procedure.

For example,

  • Concept

Although Pharmaceutical / biologic product (product) and its descendants are considered valid values for the Component (attribute), they are not currently used as values for this attribute in the International Release. The only exception is 787859002 |Vaccine product (medicinal product)| and its descendants, which are used as valid values for this attribute.

Has specimen

Has Specimen indicates the type of specimen on which a measurement or observation is performed.

Measurement method

Measurement Method specifies the method by which an evaluation procedure is performed. It provides additional specificity. For measurement procedures, the 

Concept
t260686004 |Method (attribute)|
is given the value
Concept
t129266000 |Measurement - action (qualifier value)|
.  No concept can be defined with a 
Concept
t370129005 |Measurement method (attribute)|
unless it is being used to refine a 
Concept
t260686004 |Method (attribute)|
 that has a value of 
Concept
t129266000 |Measurement - action (qualifier value)|
 
or one of its subtypes that is also specified in the concept definition. That is, use of 
Concept
t370129005 |Measurement method (attribute)|
 must be in addition to a

or one of its subtypes.

Time aspect

Time Aspect specifies temporal relationships for a measurement procedure.  While this attribute has been approved, guidelines for its implementation await development.


Further clarification

An evaluation procedure may evaluate a property of a component, or a property may be the sole focus of the method. In the latter case, component isn’t included since only the property is being evaluated.

For example of - an evaluation procedure evaluating a property property of a component,:

  • Concept
