Specification Updates HQMF Query Health TWG and HL7 SDWG Joint WG meetings every Tuesday, Wednesday Started Analysis of Ballot requirements Will be discussing specific requirements that need more targeted discussions starting next week Use the Joint WG going forward for all HQMF Issues discussion surrounding the standard Discuss implementation specific issues in the TWG and provide feedback to the Joint WG if necessary QRDA Implementation Guide Updates based on Category I is in progress Discussion of Category II and Category III Requirements and representation …in a few minutes

RI Update PopMedNet Query Envelope gaps Implementation started (Target completion – June) Continue Working on i2B2 – PMN Integration (Target completion – July) i2B2 Started integration of translators into i2b2 code base Working with NY to baseline the Ontology / CEDD for Pilot hQuery Working on identifying more subset operators required for some of the complex quality measures Started working on generating HQMF v2 using JSON hQuery Model

QRDA Requirements Discussion QRDA Category II and III Common Requirements Link QRDA to the HQMF query (document) Capture the data source providing the response Capture the time the result was created Capture the reporting period that was used to create the result Capture results uniquely for each Population Criteria section in the HQMF HQMF will have at least one Population Criteria section Each Population Criteria section will have at most one IPP, One Denominator, One Numerator, One Exclusions, One Exceptions section. There can be multiple Stratifiers within the Population Criteria section Support Specific Stratification criteria For e.g Count of patients with diabetes stratified by the following age groups Age between 14 and 21 Age between 21 and 30 etc. Support generic Stratification criteria For e.g Count of patients with diabetes stratified by Zip Codes (The Query does not enumerate all the Zip codes)

QRDA Requirements Discussion Cont’d QRDA Category II and III Common Requirements Cont’d Capture what is being counted (e.g patients, encounters, procedures) Category III Specific requirements Supports only Aggregate information and no patient level information. Category II Specific requirements Support Patient level information Only an Identifier for the patient for follow up Unlike Category I, the patient information in Category II must not contain any of the detailed information present in the medical record. So the CCDA Templates and the QDM Data Type Patterns are not applicable for Category II or III Must include all patients who qualify for IPP

QRDA II and III Representation Background: QRDA is based on the CDA document. Schemas used are the baseline CDA schemas (CDA.xsd) QRDA Category I currently in ballot QRDA II and III Header Reporting Parameters Measure Section For Query Health, the results for all the Population Criteria sections would be present within one Measure Section.

QRDA II and III Representation – Header Header Elements: (Common to both Category II and III) realmCode typeId templateId - Changes based on Category II or III Id Code Title EffectiveTime – Time when the report is generated Confidentiality Code – Could change if the Data Source chooses to Language Code RecordTarget External Document Id Reference (New in Category I) Author Informant Custodian LegalAuthenticator Proposing these to be the same for each data source

QRDA II and III Representation – Header Cont’d Header Elements XML: (Common to both Category II and III) QRDA Calculated Summary Report <!-- This is the NQF Number, root is an NQF OID for eMeasure Number and extension is the eMeasure's NQF number -->

QRDA II and III Representation – Header Cont’d Header Elements XML Cont’d: (Common to both Category II and III) Good Health Clinic Good Health Clinic Good Health Clinic Good Health Clinic

QRDA II and III Representation – Reporting Parameters List of Stratifiers from HQMF Query represented as Observations (Ids can be used to link them across QRDA / HQMF if required), Should they be ACT’s ? Present for all Queries (Numerator, Denominator, Exceptions, Exclusions, IPP)

QRDA III Representation – Measure Section ---- For a Particular Population Criteria Section The percentage of patients years of age with diabetes (type 1 or type 2) who had HbA1c > 9.0%. …… For the Next Population Criteria Section Stratifier designated as an ACT and Referencing by id element Aggregate Data Elements represented as Observations supporting the ACT

QRDA II Representation – Measure Section The percentage of patients years of age with diabetes (type 1 or type 2) who had HbA1c > 9.0%. Patient Information Stratifier’s designated as observations Common Aggregate Data Elements (Numerator, Denominator …)
