PathCardinalityTypeDescription
Evidence0..*EvidenceThe Evidence Resource provides a machine-interpretable expression of an evidence concept including the evidence variables (eg population, exposures/interventions, comparators, outcomes, measured variables, confounding variables), the statistics, and the certainty of this evidence.
Evidence.id0..1http://hl7.org/fhirpath/System.StringThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Evidence.meta0..1MetaThe metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
Evidence.implicitRules0..1uriA reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Evidence.language0..1codeThe base language in which the resource is written.
Evidence.text0..1NarrativeA human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
Evidence.contained0..*ResourceThese resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.
Evidence.extension0..*ExtensionMay be used to represent additional information that is not part of the basic definition of the resource. 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.
Evidence.modifierExtension0..*ExtensionMay be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it 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 is allowed to 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).
Evidence.url0..1uriAn absolute URI that is used to identify this evidence 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 summary is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the summary is stored on different servers.
Evidence.identifier0..*IdentifierA formal identifier that is used to identify this summary when it is represented in other formats, or referenced in a specification, model, design or an instance.
Evidence.version0..1stringThe identifier that is used to identify this version of the summary when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the summary 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.
Evidence.title0..1stringA short, descriptive, user-friendly title for the summary.
Evidence.citeAs[x]0..1ReferenceCitation Resource or display of suggested citation for this evidence.
Evidence.status1..1codeThe status of this summary. Enables tracking the life-cycle of the content.
Evidence.date0..1dateTimeThe date (and optionally time) when the summary 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 summary changes.
Evidence.useContext0..*UsageContextThe 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 evidence instances.
Evidence.approvalDate0..1dateThe date on which the resource content was approved by the publisher. Approval happens once when the content is officially approved for usage.
Evidence.lastReviewDate0..1dateThe date on which the resource content was last reviewed. Review happens periodically after approval but does not change the original approval date.
Evidence.publisher0..1stringThe name of the organization or individual that published the evidence.
Evidence.contact0..*ContactDetailContact details to assist a user in finding and communicating with the publisher.
Evidence.author0..*ContactDetailAn individiual, organization, or device primarily involved in the creation and maintenance of the content.
Evidence.editor0..*ContactDetailAn individiual, organization, or device primarily responsible for internal coherence of the content.
Evidence.reviewer0..*ContactDetailAn individiual, organization, or device primarily responsible for review of some aspect of the content.
Evidence.endorser0..*ContactDetailAn individiual, organization, or device responsible for officially endorsing the content for use in some setting.
