Detailed Descriptions for the elements in the Measure resource.

Measure
Element IdMeasure
Definition

The Measure resource provides the definition of a quality measure.

Measure.url
Element IdMeasure.url
Definition

An absolute URI that is used to identify this measure when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which an authoritative instance of this measure is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the measure is stored on different servers.

Short DisplayCanonical identifier for this measure, represented as a URI (globally unique)
Cardinality0..1
Typeuri
Requirements

Allows the measure to be referenced by a single globally unique identifier.

Summarytrue
Comments

Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version.

The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions.

In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found.

Measure.identifier
Element IdMeasure.identifier
Definition

A formal identifier that is used to identify this measure when it is represented in other formats, or referenced in a specification, model, design or an instance.

Short DisplayAdditional identifier for the measure
NoteThis is a business identifier, not a resource identifier (see discussion)
Cardinality0..*
TypeIdentifier
Requirements

Allows externally provided and/or usable business identifiers to be easily associated with the module.

Summarytrue
Comments

Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this measure outside of FHIR, where it is not possible to use the logical URI.

Measure.version
Element IdMeasure.version
Definition

The identifier that is used to identify this version of the measure when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the measure author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification. Note that a version is required for non-experimental active artifacts.

Short DisplayBusiness version of the measure
NoteThis is a business versionId, not a resource version id (see discussion)
Cardinality0..1
Typestring
Summarytrue
Comments

There may be different measure instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the measure with the format [url]|[version]. The version SHOULD NOT contain a '#' - see Business Version.

Measure.name

A Boolean value to indicate that this measure is authored for testing purposes (or education/evaluation/marketing) and is not intended to be used for genuine usage.

Short DisplayFor testing purposes, not real usage

Measure.subject[x]
Element IdMeasure.subject[x]

Short DisplayE.g. Patient, Practitioner, RelatedPerson, Organization, Location, Device
Cardinality0..1
Terminology BindingParticipant Resource Types (Extensible)
TypeCodeableConcept|Reference(Group)
[x] NoteSee Choice of Datatypes for further information about how to use [x]
Meaning if MissingPatient
Summaryfalse
Comments

The subject of the measure is critical in interpreting the criteria definitions, as the logic in the measures is evaluated with respect to a particular subject. This corresponds roughly to the notion of a Compartment in that it limits what content is available based on its relationship to the subject. In CQL, this corresponds to the context declaration.

Measure.basis
Element IdMeasure.basis
Definition

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.

Short DisplayPopulation basis
Cardinality0..1
Terminology BindingAll FHIR Types (Required)
Typecode
Meaning if Missingboolean
Requirements

Allows non-subject-based measures to be specified

Summarytrue
Comments

For a subject-based measure, the population basis is simply boolean; all the criteria are expressed as true/false conditions that determine membership of an individual case in the population. For non-subject-based measures, the population basis can be any resource type, and the criteria are queries that return the subject's contribution to the population as a list of that resource type. For example, for a procedure-based measure, the population criteria would return lists of procedures that should be included in each population.

Measure.date
Element IdMeasure.date
Definition

The date (and optionally time) when the measure was published. The date must change when the business version changes and it must change if the status code changes. In addition, it should change when the substantive content of the measure changes.

Measure.useContext
Element IdMeasure.useContext

Comments

The measure rate for an organization or clinician is based upon the entities’ aggregate data and summarizes the performance of the entity over a given time period (e.g., monthly, quarterly, yearly). The aggregated data are derived from the results of a specific measure algorithm and, if appropriate, the application of specific risk adjustment models. Can also be used to describe how to risk adjust the data based on supplemental data elements described in the eMeasure (e.g., pneumonia hospital measures antibiotic selection in the ICU versus non-ICU and then the roll-up of the two). This could be applied to aggregated cohort measure definitions (e.g., CDC's aggregate reporting for TB at the state level).
