CQFM Aggregate Method |
Specifies which method to be used to aggregate the measure observation values. |

CQFM Component |
Specifies an artifact this is a component of a composite artifact. |
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. |

Please provide comments on this additional code and if there are other codes needed in the improvement notation value set. If an additional code is added to the improvement notation (like normative reference range as suggested), where is guidance about the reference range best included in the specification for implementer use? Some suggestions include: the guidance field, the rate aggregation field or adding an extension to improvementNotation to add text. |
CQFM Include In Report Type |
Indicates what types of report the element on which it appears should be included in. If no values are specified, the default behavior is that elements are included in all report types |
CQFM Is Test Case |
Indicates whether this instance represents the definition of a test case. |
CQFM Operation |
Specifies the operation definition |
CQFM Population Basis |
The population basis specifies the type of elements in the population. For a subject-based measure, this is boolean (because the subject and the population basis are the same, and the population criteria define yes/no values for each individual 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. Note that the subject of a measure can be found in the element subject[x]. |
CQFM Rate Aggregation |
Describes how to combine the information calculated, based on logic in each of several populations, into one summarized result. |
CQFM Risk Adjustment |
A description of the risk adjustment factors that may impact the resulting score for the measure and how they may be accounted for when computing and reporting measure results. |
CQFM 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. |
CQFM Scoring Precision |
The number of decimal places to include in the score when the score is a decimal-valued result. |
CQFM Scoring Unit |
Defines the expected units of measure for the measure score. |
CQFM Supplemental Data Guidance |
Provides additional guidance on the meaning and reporting of supplemental data elements included in the measure overall. |
CQFM Test Case Description |
Provides a clear description of the test case. |
CQFM Type |
Indicates whether the measure is used to examine a process, an outcome over time, a patient-reported outcome, or a structure measure such as utilization. |
CQFM Weight |
What is the weight of the contribution of this measure to the overall score. |
