Structures: Extension Definitions

These define constraints on FHIR data types for systems conforming to this implementation guide.

CQM Aggregate Method

Specifies which method to be used to aggregate the measure observation values.

CQM Applies To

Indicates the population that this stratifier should apply to. If no appliesTo extension is present, the stratifier is calculated based on the result of the population calculation (e.g. the calculated numerator for a proportion scoring).

CQM Component

Specifies an artifact this is a component of a composite artifact.

CQM 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.

CQM Criteria Reference

Specifies which population criteria is the input to an observation definition, or the initial population for a ratio numerator or denominator.

CQM Effective Period Anchor

Specifies the anchor date for the effective period as defined by a starting date and a range.

CQM Effective Period Duration

Specifies the reporting period for the measure.

CQM Group Id

Specifies the id of a particular group within the measure referenced by the related artifact resource.

CQM Improvement Notation

Information on whether an increase or decrease in score is the preferred result (e.g., a higher score indicates better quality OR a lower score indicates better quality OR quality is within a range).

Additional Guidance: improvementNotation

Reference range with definition of score within a defined interval (or a “passing score” over or under a certain threshold) indicates better quality to the improvement notation value set. Please provide comments on this additional code and if there are other codes needed in this value set.

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.

CQM 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

CQM Is Test Case

Indicates whether this instance represents the definition of a test case.

CQM Operation

Specifies the operation definition

CQM 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].

CQM Rate Aggregation

Describes how to combine the information calculated, based on logic in each of several populations, into one summarized result.

CQM 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.

CQM 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.

CQM Scoring Precision

The number of decimal places to include in the score when the score is a decimal-valued result.

CQM Scoring Unit

Defines the expected units of measure for the measure score.

CQM Supplemental Data Guidance

Provides additional guidance on the meaning and reporting of supplemental data elements included in the measure overall.

CQM Test Case Description

Provides a clear description of the test case.

CQM 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.

CQM Weight

What is the weight of the contribution of this measure to the overall score.
