III. DEFINING POPULATIONS
The required and optional populations for the measure scoring type will be listed within the
[Populations] sub-tab of the [Population Workspace]. To define a measure population, users will add
logical operators and clauses built within the [Clause Workspace]. Instructions for adding a logical
operator and/or a clause are provided next.
A. Adding a Logical Operator to a Population
There are four available logical operators available to add to a measure population AND, AND NOT,
OR, and OR NOT. These are used to link the measure logic clauses built within [Clause Workspace].
The top level logical operator is the first operator in the logic tree following the population name.
The top level logical operator may not be removed. The top level logical operator for the following
populations defaults to ‘AND’: Initial Populations, Numerators, Denominators, and Measure
Populations. The top level logic operator for the following populations defaults to ‘OR’: Numerator
Exclusions, Denominator Exclusions, Denominator Exceptions, and Measure Population Exclusions.
Instructions for adding a logical operator to a measure population are provided next.
1. On the [Populations] sub-tab of the [Population Workspace], identify the population where
the logical operator will be added.
