Elements

PathShortDefinitionComments
A population, intervention, or exposure definitionThe ResearchElementDefinition resource describes a "PICO" element that knowledge (evidence, assertion, recommendation) is about.PICO stands for Population (the population within which exposures are being compared), Intervention (the conditional state or exposure state being described for its effect on outcomes), Comparison (the alternative conditional state or alternative exposure state being compared against), and Outcome (the result or effect of the intervention in the population).
urlCanonical identifier for this research element definition, represented as a URI (globally unique)An absolute URI that is used to identify this research element definition 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 at which an authoritative instance of this research element definition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the research element definition is stored on different servers.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](resource.html#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](resource.html#meta) element to indicate where the current master source of the resource can be found.
identifierAdditional identifier for the research element definitionA formal identifier that is used to identify this research element definition when it is represented in other formats, or referenced in a specification, model, design or an instance.Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this research element definition outside of FHIR, where it is not possible to use the logical URI.
versionBusiness version of the research element definitionThe identifier that is used to identify this version of the research element definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the research element definition 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.There may be different research element definition 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 research element definition with the format [url]|[version].
nameName for this research element definition (computer friendly)A natural language name identifying the research element definition. This name should be usable as an identifier for the module by machine processing applications such as code generation.The name is not expected to be globally unique. The name should be a simple alphanumeric type name to ensure that it is machine-processing friendly.
titleName for this research element definition (human friendly)A short, descriptive, user-friendly title for the research element definition.This name does not need to be machine-processing friendly and may contain punctuation, white-space, etc.
shortTitleTitle for use in informal contextsThe short title provides an alternate title for use in informal descriptive contexts where the full, formal title is not necessary.
subtitleSubordinate title of the ResearchElementDefinitionAn explanatory or alternate title for the ResearchElementDefinition giving additional information about its content.
statusdraft | active | retired | unknownThe status of this research element definition. Enables tracking the life-cycle of the content.Allows filtering of research element definitions that are appropriate for use versus not.
experimentalFor testing purposes, not real usageA Boolean value to indicate that this research element definition is authored for testing purposes (or education/evaluation/marketing) and is not intended to be used for genuine usage.Allows filtering of research element definitions that are appropriate for use versus not.
subject[x]E.g. Patient, Practitioner, RelatedPerson, Organization, Location, DeviceThe intended subjects for the ResearchElementDefinition. If this element is not provided, a Patient subject is assumed, but the subject of the ResearchElementDefinition can be anything.The subject of the ResearchElementDefinition is critical in interpreting the criteria definitions, as the logic in the ResearchElementDefinitions 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.
dateDate last changedThe date (and optionally time) when the research element definition 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 research element definition changes.Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the research element definition. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.
publisherName of the publisher (organization or individual)The name of the organization or individual that published the research element definition.Usually an organization but may be an individual. The publisher (or steward) of the research element definition is the organization or individual primarily responsible for the maintenance and upkeep of the research element definition. This is not necessarily the same individual or organization that developed and initially authored the content. The publisher is the primary point of contact for questions or issues with the research element definition. This item SHOULD be populated unless the information is available from context.
contactContact details for the publisherContact details to assist a user in finding and communicating with the publisher.May be a web site, an email address, a telephone number, etc.
descriptionNatural language description of the research element definitionA free text natural language description of the research element definition from a consumer's perspective.This description can be used to capture details such as why the research element definition was built, comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the research element definition as conveyed in the 'text' field of the resource itself. This item SHOULD be populated unless the information is available from context (e.g. the language of the research element definition is presumed to be the predominant language in the place the research element definition was created).
commentUsed for footnotes or explanatory notesA human-readable string to clarify or explain concepts about the resource.
useContextThe context that the content is intended to supportThe content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, ...) or may be references to specific programs (insurance plans, studies, ...) and may be used to assist with indexing and searching for appropriate research element definition instances.When multiple useContexts are specified, there is no expectation that all or any of the contexts apply.
jurisdictionIntended jurisdiction for research element definition (if applicable)A legal or geographic region in which the research element definition is intended to be used.It may be possible for the research element definition to be used in jurisdictions other than those for which it was originally designed or intended.
purposeWhy this research element definition is definedExplanation of why this research element definition is needed and why it has been designed as it has.This element does not describe the usage of the research element definition. Instead, it provides traceability of ''why'' the resource is either needed or ''why'' it is defined as it is. This may be used to point to source materials or specifications that drove the structure of this research element definition.
usageDescribes the clinical usage of the ResearchElementDefinitionA detailed description, from a clinical perspective, of how the ResearchElementDefinition is used.

characteristicWhat defines the members of the research elementA characteristic that defines the members of the research element. Multiple characteristics are applied with "and" semantics.Characteristics can be defined flexibly to accommodate different use cases for membership criteria, ranging from simple codes, all the way to using an expression language to express the criteria.
characteristic.idUnique id for inter-element referencingUnique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
characteristic.extensionAdditional content defined by implementationsMay 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.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.
characteristic.modifierExtensionExtensions that cannot be ignored even if unrecognizedMay be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. 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. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).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.
