II. BUILDING CLAUSE LOGIC
After a clause is named, the measure author begins defining the logic. First let’s review the tools
available to the measure author when building a measure clause.
A. Available Tools
When the measure developer performs a right-click on the clause name (e.g., Encounters), a menu
displays with the following options: Add, Copy, Paste, Cut, Delete, Expand, Edit, and View Human
Readable. By hovering over ‘Add’ an expanded menu is displayed with the following options: Union,
Intersection, QDM element, Timing, Functions, and Relationship.
The steps for building four common measure clauses are reviewed in the Build a Measure
Clause section of this chapter. The following are options within the expanded ‘Add’ menu of the
Union is a subset operator which can be used when constructing a measure clause. To
review use cases for the set operators Union and Intersection, review the
Quality Data Model.
Once Union is added to the measure logic, at least one child node must be added to the
subset operator Union. The options to add Union, Intersection, QDM Element, Timing,
Functions, Relationships, and an existing Clause are enabled, as pictured below.
