StructureDefinition: MeasureCriteria - Detailed Descriptions

Definitions for the MeasureCriteria Profile.

1. Expression
Definition

A expression that is evaluated in a specified context and returns a value. The context of use of the expression must specify the context in which the expression is evaluated, and how the result of the expression is used.

Control0..* This element is affected by the following invariants: ele-1
InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
exp-1: An expression or a reference must be provided (: expression.exists() or reference.exists())
2. Expression.id
Definition

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

Control0..1
Typestring
3. Expression.extension
Definition

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

Control0..*
TypeExtension
Alternate Namesextensions, user content
Comments

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
SlicingThis element introduces a set of slices on Expression.extension. The slices are unordered and Open, and can be differentiated using the following discriminators:
  • value @ url
4. Expression.description
Definition

A brief, natural language description of the condition that effectively communicates the intended semantics.

Control1..1
Typestring
InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
5. Expression.name
Definition

A short name assigned to the expression to allow for multiple reuse of the expression in the context where it is defined.

Control1..1
Typeid
InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. Expression.language
Definition

The media type of the language for the expression.

Control1..1
BindingThe media type of the expression language.
The codes SHALL be taken from ExpressionLanguage; other codes may be used where these codes are not suitable

InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. Expression.expression
Definition

An expression in the specified language that returns a value.

Control1..1
Typestring
InvariantsDefined on this element
ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
8. Expression.reference
Definition

A URI that defines where the expression is found.

Control0..1
Typeuri
Comments

If both a reference and an expression is found, the reference SHALL point to the same expression.
