Evidence Based Medicine on FHIR Implementation Guide, published by HL7 International / Clinical Decision Support. This guide is not an authorized publication; it is the continuous build for version 1.0.0-ballot3 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/ebm/ and changes regularly. See the Directory of published versions

The Evidence Based Medicine on FHIR Implementation Guide Code System and Recommendation Justification Code System are currently created within the EBMonFHIR IG. As this IG matures, it is the expectations that terms used will be moved in preferential order to:

This code system is a temporary workspace while drafting the Evidence Based Medicine Implementation Guide. It may not be stable and may not be persistent.
This resource (this entire set of content) is being used for active development of a code system to support a RecommendationJustification Profile of ArtifactAssessment Resource. This code system is not yet released for expected use and may not be stable. This resource may be used for the continuous development of the code system, and published versions of the code system (when ready) may be published as separate resources with stable identifiers.
This CodeSystem is used for common values for the ResearchStudy.classifier element and will likely move to terminology.hl7.org when it is mature.
Codes for use with the OutcomeImportance Profile, to provide values for the content.classifier element where content.type is Outcome Desirabiltiy.
Profile Names in the Evidence Based Medicine on FHIR (EBMonFHIR) Implementation Guide.

Codes for use with the Classifier drop-down menu for FEvIR(R): Recommendation Justification Builder.

Codes for use in the DocumentReference.type element when referenced from ResearchStudy.relatesTo.targetReference.
Codes for use in the Group.characteristic.code element in a SearchStrategy Profile.
These codes represent the types of identifier used in a study. This is a UDP specific value set. These are codes used in M11 but in the M11 Specification each code is associated with a distinct M11 attribute rather than being a classifier for a more general attribute. FHIR structures are designed to work with a repeating identifier attribute classified by an approriate terminology. This value set enables that by using NCIT codes to create a FHIR value set.

These codes represent the types of role ResearchStudy.associatedParty can play. This is required for the mechanism used by FHIR for associating one entity with another. This is a UDP specific value set and uses NCIT codes to create an appropriate FHIR value set.
