   or a defined collection of data items in an

   information model.  The clinical meaning represented by of an instance of a data item with a meaning binding is determined by applying the meaning bindingto the value or set of values in that instance. The

Example

• An application that manages surgical procedure requests could identify requested procedures using concepts that are subtypes of 

  Concept
  t 387713003 Surgical procedure

  . In this case, the data item in which that concept is recorded should have a meaning binding that explicitly indicates that this is a request (e.g. the for that procedure. The expression template below ). When this meaning binding is applied this data item is interpreted as a subtype of 

  Concept
  t 400999005 Procedure requested (situation)

   and not as a completed procedure.represents this meaning binding. It indicates that the procedure selected should replace the "@procedure" 

  Gloss

  , resulting in an 

  Gloss
  t expression

   that means procedure has been requested, rather than suggesting incorrectly, that it has been done.

400999005 |Procedure requested (situation)|:
      { 363589002 |Associated procedure (attribute)| = [[ +id <387713003 |Surgical procedure| @procedure ]] }

/* Resulting Expression if "38102005 Cholecystectomy (procedure)" is entered */
