When selections are made using this control the appropriate Concept identifier is added to the record.Binding Concept to a Particular Combination of Values or the Result of a Computation Involving Several Items of Previously Entered Data
Figure 6.2.5-5: Two examples of how data entry of specific values can be foundation for automatic addition of appropriate SNOMED CT clinical findings
When specific values are entered the appropriate (defined) Concept identifier is added to the record. The above examples show how specific numeric values can lead to specific clinical findings, based on pre-defined rules.
The example at the bottom of Figure 39, illustrate that the BMI can be automatically calculated by the entered values for body weight and height. Moreover, it is possible to develop rule-based coding (i.e. algorithms that assign BMI values between 20 and 24 to the SNOMED CT Concept 35425004 | normal body mass index |, or to a more specific Concept 412768003 | body mass index 20-24 - normal |.
