STU3 Release for FHIR R4 (v3.0.0)

This release includes changes due to ballot reconciliation and connectathon testing. The following sections summarize the changes from the balloted version (v2.*0), followed by a detailed changes list of all changes applied.

Terminology Services Change Summary

Changes to the CQFMExecutableValueSet profile:
  • Changed the warning extension from cqfm-usageWarning to valueset-warning (base extension)
  • Changed the fixed value of the warning extension to discuss conformance only (moved guidance to the IG)
  • Changed expansion contains elements to require a version unless the parameters element has a system-version for the system
Changes to the CQFMQualityProgram profile:
  • Removed cqfm-activeOnly and cqfm-expansionUri extensions in favor of the more general cqfm-expansionParameters extension
Changes to the ValueSet/$expand operation:
  • Clarified semantics of the manifest parameter
  • Clarified semantics of the expansion parameter
  • Changed includePreview parameter to includeDraft
Changes to the Measure Terminology Service:
  • Added Expansion Rules to describe expected expansion behavior in the presence of a manifest
  • Recommended support for useContext search parameters
  • Recommended support for reference search parameters
Changes to align with FHIR publishing
  • Added support for the terminology model of a server’s capability statement
  • Added support for batch operations for $validate-code
  • Required support for activeOnly and displayLanguage in $validate-code
  • Required support for activeOnly, displayLanguage, limitedExpansion, and default-to-latest-version parameters in $expand
  • Recommended support for includeDesignation, designation, and paging parameters in $expand
Outstanding Questions
  • Search by URL should return all versions with that URL, otherwise there is no way to get the list of versions for a given value set URL
  • If searches return a SUBSETTED resource by default, should the server should allow the _summary=false parameter to request full resources?
  • Given the id of a ValueSet is the OID, how can I retrieve specific versions of a ValueSet?
  • How can I retrieve a list of available expansions for a given ValueSet URL?
  • Can I use a GET to invoke $expand with both the url and valueSetVersion parameters? (Connectathon testing resulted in an error)

Measure Representation Change Summary

Changes to the CQFMMeasure profile:
  • Required CQFMMeasure Library reference to be a CQFMLibrary
  • Relaxed scoring, type, and improvementNotation cardinality
Changes to the CQFMComputableMeasure profile:

  • Added valueFilter extension to support additional filtering in dataRequirement
  • Added constraints to enforce scoring, populationBasis, and improvementNotation be specified at the root or all groups, but not both

  • Required Library to be a CQFMComputableLibrary and all expressions to be text/cql-expression or -identifier
Added CQFMExecutableMeasure
  • Required Library to be a CQFMExecutableLibrary and all expressions to be text/cql-identifier
Changes to measure repository service:
  • Removed the bundle-based packaging profiles in favor of artifact-based profiles to ensure artifact packaging can use paging when artifact packages contain a large number of components
  • Added support for advertising CQL version support
Changes to measure authoring:
  • Allowed any number of models to be referenced, rather than requiring one and only one reference to QICore
  • Recommended not disabling method invocation to allow fluent functions to be used
  • Added support for mixed-basis ratio measure
  • Added ability to associated stratifiers with specific populations
  • Added the ability to specify scoringUnit for a measure

STU2 Ballot for FHIR R4 (v**0)

This ballot is a minimal update to the STU1 ballot to address the following items:

  • Updated to use FHIR R4
  • Added artifact packaging guidance and conformance requirements

STU1 Release for FHIR STU3 (v*0.0)

  • Clarifications and fixes throughout

Compatible, substantive

  • 21181 *.1 relationships
  • 21684 Risk adjustment naming conventions? - QM #15
  • 21156 Clarify where the risk adjustment variables are stored in the fhir document.
  • 21155 Inconsistent conformance requirements (16 and 17).
  • 21986 Denominator exceptions in differential table? - QM #136
  • 21988 Supporting measurement period without specifying year? - QM #137
  • 21145 conformance requirement 13 states that a continuous variable measure SHALL have a criteriaReference extension but the profile has this extension as 0..1 rather than . Should the profile have *.1?
  • 21187 consider for all slices that are not “measure observation” to make cqfm-criteriaReference and cqfm-aggregateMethod 0..0
  • 21183 initial population slice for proportion measure is .2. Should be *. (*.2 is for ratio measure).
  • 21192 EXM55 library references
  • 21178 Does it make sense for the profile itself to specify usage for criteriaReference and aggregateMethod (measure observations)
  • 21191 consider slicing content and including the required contentType (text/cql) and optional ones (application/elm+xml, application/elm+json)
  • 21984 Require use of specific model? - QM #135
  • 21158 Should this be a conformance requirement?
  • 21188 consider making cqfm-criteriaReference and cqfm-aggregateMethod *.1 for “measure observation” slice.
  • 21186 measure population exclusion slice should be 0..* population.code for this slice should still be required (*.1)
  • 21182 should population.identifier, supplementalData.identifier and stratification.identifier be required?
  • 21185 missing denominator exception slice
  • 21173 This statement uses SHOULD NOT language but the conformance requirement is SHALL NOT. Recommend rewording for clarity.
  • 21146 should conformance requirement 13 require an aggregateMethod extension on the measure observation criteria? It currently does not.

Non-compatible

  • 21998 Restrict stratification of ratio measure - QM #142
  • 21994 Library namespace guidance - QM #140
  • 21056 Disallow the use of strings for membership testing in value sets and code systems
  • 21996 Library alias guidance - QM #141
