A Procedure Plan is a specification that defines the set of Protocols that must be done in order to perform the Scheduled Procedure Steps of a Requested Procedure. Each Scheduled Procedure Step is preformed according to a single Protcol which may be identified by one or more Protocol Codes. The Protocols actually performed during a Procedure Step may differ from those prescribed in the related Procedure Plan. Audit of actually performed Protocols versus the prescribed Procedure Plan is an important element of quality control, but is not specified by this Standard.
Note: The fact that Protocols Codes are in a given order in a Procedure Plan is not evident in Figure 7.3. However, the order of Protocols is represented at the syntax level (i.e. as the sequence of items present in the Protocol Code Sequence (0040,0008)).
