CQFM Population Basis |
The population basis specifies the type of elements in the population.

For measures that have a population basis that is different than the subject, this element specifies the type of the population basis. For example, an encounter-based measure has a subject of Patient and a population basis of Encounter, and the population criteria all return lists of Encounters. |

CQFM Composite Scoring |
Indicates how the calculation is performed for the measure, including proportion, ratio, continuous-variable, and cohort. The value set is extensible, allowing additional measure scoring types to be represented. When present on a group, specifies the scoring to be used for this group, overriding the scoring specified for the overall measure. |

Provides an identifier for the measure within the program. |
CQFM Aggregate Method |
Specifies which method to be used to aggregate the measure observation values. |
CQFM Is Selective |
Allows a given data requirement to be identified as “selective”, meaning that it can be used as an additive criteria to filter a population. A selective data requirement is guaranteed to define a subset (not necessarily proper) of the initial population of a measure. If multiple data requirements are marked selective, they all apply (i.e. AND semantics). |

An extra warning about the correct use of the value set. |
