A qualifying
Glossary ref
Gloss
Spacetrue
tqualifying characteristic
is an attribute that may have one of several possible values for a particular glossary-ref
Gloss
tConcept
. If a particular glossary-ref
Gloss
tqualifier
is applied to a glossary-ref
Gloss
tConcept
, the resulting glossary-ref
Gloss
texpression
represents a more tightly defined glossary-ref
Gloss
tsubtype
of that glossary-ref
Gloss
tConcept
.

Example: It might be possible to qualify a disorder such as

scg-expression
Concept
ShowParts
t
term
53084003|bacterial
pneumonia|
according to its clinical course ( scg-expression
Concept
ShowParts
t
term
53737009|acute|
or scg-expression

t
term
90734009|chronic|
) or severity ("mild," "moderate" or scg-expression
Concept
ShowParts
t
term

). With appropriate glossary-ref
Gloss
tqualifiers
, "injury of skin of the left side of face" could then be represented even if a single glossary-ref
Gloss
tConcept
Identifier
cannot express this.

A similar tightening of the definition of a

glossary-ref
Gloss
tConcept
can be achieved by allowing one or more of the glossary-ref
Gloss
tdefining
characteristics
associated with a glossary-ref
Gloss
tConcept
to be refined. A glossary-ref
Gloss
tdefining
characteristic
is refined by an glossary-ref
Gloss
texpression
that applies a specified glossary-ref
Gloss
tsubtype
of the value stated in the definition.

Example:

scg-expression
Concept
ShowParts
t
term
125605004|Fracture
of
bone|
could be refined by qualifying it with the finding site"tibia" to represent the Scg expression
