  1. HQMF R2.1 Updates Modularization, Episode of Care, Composite Measure Metadata

  2. Composite Measure Metadata

  3. HQMF R2 • Currently allowed typeCode values: • RPLC: replaces (prior version of measure in HQMF syntax) • XFRM: transformation of (prior document to HQMF syntax) • APND: is appendage of <relatedDocumenttypeCode="RPLC"><parentQualityMeasureDocument><id root="8a4d92b2-35fb-4aa7-0136-1df6d8c70252"/><setId root="2.16.840.1.113883.3.100.1" extension="BEB1C33C-2549-4E7F-9567-05ED38448464"/><versionNumber value="1.1"/></parentQualityMeasureDocument></relatedDocument>

  4. HQMF R2.1 • Additional typeCode values for reference to components of composite (HL7 ActRelationshipType) • New codes • XCRPT: excerpts • VRXCRPT: verbatim excerpts • DRIV: derived from • COMP: has component (jointly authored) • USE: uses (independently authored) • Additional relatedDocument child element • componentQualityMeasureDocument ?

  5. HQMF R2.1 Example <relatedDocumenttypeCode=”USE"><componentQualityMeasureDocument><id root="8a4d92b2-35fb-4aa7-0136-1df6d8c70252"/><setId root="2.16.840.1.113883.3.100.1" extension="BEB1C33C-2549-4E7F-9567-05ED38448464"/><versionNumber value="1.1"/></componentQualityMeasureDocument></relatedDocument>

  6. HQMF Modularization

  7. Separate Expression Logic andExpression Data Model

  8. Identify Source of Expressions <relatedDocumenttypeCode=”COMP"><expressionDocument><id root="22688A59-B73C-4276-9E83-778214E1CA3C"/><text mediaType="application/javascript"> <reference value="expression.js"/> </text></expressionDocument></relatedDocument>

  9. Use an Expression from HQMF <preconditiontypeCode="PRCN"><criteriaReferenceclassCode="OBS"moodCode="EVN"><id root="22688A59-B73C-4276-9E83-778214E1CA3C”extension="InpatientEncounterLOSLessThan120"/></criteriaReference></precondition>

  10. Define Data in HQMF <entrytypeCode="DRIV"> <localVariableName value="InpatientEncounter"/> <encounterCriteriaclassCode="ENC"moodCode="EVN"> <id root="e9a068dc-310a-48e4-95b0-eed852a8950b" extension="inpatientEncounter"/> <codevalueSet="2.16.840.1.113883.3.666.5.3001”codeSystem="2.16.840.1.113883.3.560.101.1"> <displayName value="Encounter Inpatient SNOMED-CT Value Set"/> </code> <title value="Inpatient encounter"/> <definition> <criteriaReferenceclassCode="ACT"moodCode="EVN"> <id root="2.16.840.1.113883.3.560" extension="EncounterPerformed"/> </criteriaReference> </definition> </encounterCriteria> </entry>

  11. Access Data from Expression HeD <operandxsi:type="Filter" scope="EncounterScope"> <sourcexsi:type="ExpressionRef" name="InpatientEncounter"/> … </operand> JavaScript varinpatientEncounters = patient.InpatientEncounter();

  12. Episode of CARE Measures

  13. HQMF R2 • Added a new ITMCNT measure attribute • Specified at the document or population level • Value is a CD specifying generic “procedure”, “encounter” etc.

  14. HQMF R2 ITMCNT <subjectOf> <measureAttribute> <code code="ITMCNT"codeSystem="2.16.840.1.113883.5.4"> <displayName value="Items to count"/> </code> <valuexsi:type="CD" code="71388002"codeSystem="2.16.840.1.113883.6.96"> </measureAttribute> </subjectOf>

  15. HQMF R2.1 • Analysis of MU2 episode of care measures reveals additional requirements • Need to differentiate between counted and non-counted items of same type • Need to support multiple counted items of same or different types • Update specification text • ITMCNT attribute value will be an II with @root and @extension corresponding to data criteria that represents items to be counted • Multiple ITMCNT attributes when required • No changes to XML schema

  16. HQMF R2.1 ITMCNT <subjectOf> <measureAttribute> <code code="ITMCNT"codeSystem="2.16.840.1.113883.5.4"> <displayName value="Items to count"/> </code> <valuexsi:type="II" root="e9a068dc-310a-48e4-95b0-eed852a8950b" extension="inpatientEncounter"/> </measureAttribute> </subjectOf>

  17. Summary

  18. Summary of Proposed Changes • Additional values for relatedDocument/@typeCode • Current: XFRM, RPLC, APND • Additional: COMP, USE, DRIV, XCRPT • Additional relatedDocumentchild elements • Current: parentQualityMeasureDocument • Additional: expressionDocument, componentQualityMeasureDocument • Change documentation of ITMCNT measure attribute • Describe use of data criteria reference via instance identifier
