Administrative Reminders • All the F2F material, meeting minutes and discussions are posted at: • http://wiki.siframework.org/S%26I+2012+Face+to+Face+%28F2F%29+Meeting+-+Query+Health+Meetings
F2F Summary – Single Slide • Established clear goals to deliver Query Health Specifications, RI and Pilots. • Specifications • HQMF – Agreed on IG outline and key areas that need to be further analyzed/flushed out before completing the IG. • QRDA – Identified areas and deficiencies of the current IG • Query Envelope – Release for Consensus on 4/20/2012 • Reference Implementation • HQMF Translators – Identified intermediate UML/XML model that simplifies the ability to translate from HQMF to procedural outputs • Pilots • Established near term timeline and milestones • Made key decisions for NY Pilot ontology and vocabulary • Made decisions on conceptual / physical architecture for the pilot.
F2F Summary • Thursday Morning RI and Coding Sessions: • Reviewed existing SQL Translator • Reviewed Java Script Translator • Discussed the complexity of translating from HQMF to implementation languages like SQL / Java Script etc. • Key Outcome: Outlined approach to solve the problem in a generic way such that it is easier to accomplish the required translation. • HQMF Intermediate Model (UML and XML) Implementation Language • Intermediate Model based on translation experience gained through SQL and Java Script Translators. • Model captures the required elements for the translation and reduces the amount of RIM/HL7 Expertise required. • Thursday Morning HQMF and QRDA Sample Representation Sessions • Provided overview of HQMF and QRDA to volunteers and community participants • Received a number of good comments based on current QRDA ballot and made notes on changes required
F2F Summary Cont’d • Thursday Morning Pilot Sessions: (NY DOH) • Discussed Pilot Plans and other activities. • Key Outcomes: • Create an Ontology Tree for Queries in i2B2 based on Green CDA representation. • Vocabularies to be based on a combination of i2B2 SHRINE, i2B2 SMART and i2B2 Demo ontologies. • Capture creation of ontologies and mapping of e-Clinical Works data model process to add to the CEDD Implementation Guidance sections to guide future efforts • Decided on the Pilot Architecture for instantiating the test system.

F2F Summary Cont’d • Thursday Afternoon Session – HQMF Review • Key Activity : Reviewed HQMF issues list and Sample Measures from NQF • Key Outcomes: • Identified Areas that need to be flushed out further with samples and additional work: • Expression Formats • Analyze Java Scripts availability on various platforms before finalizing recommendation • Temporally Related ActRelationship needs to further flushed out with examples • Add Header Element to address Patient Level Queries • Support Multiple Population criteria elements within a Query but constrain HQMF to carry a single query. • Ability to count things other than patients like encounters • Ratio and Continuous Variable Measures from NQF: • These are complex measures and require the ability to perform MATH calculations such as average, median etc. • Need to re-evaluate the needs of these capabilities from a pilot / CQM coverage standpoint.
F2F Summary Cont’d • Friday Morning Session – QRDA Review • Key Activity: Reviewed QRDA IG • Key Outcomes: • Synchronize IG with current ballot modifications for QRDA Level 1 • Add definitions and concepts to IG and align with HQMF • Define XML Structure for stratification of results • Define XML Structure for multiple numerators/denominators within a query • Define XML structure for linking to HQMF document • Add examples for queries and their results
HQMF Translator – UML Model • From the F2F we decided to translate from HQMF to Implementation languages it would be really efficient to have a UML Model that can be used as a standard. • HQMF UML Model (Implemented as XSD) SQL / Java Script etc.
Next Steps • Consensus Voting • Please submit your votes for Query Envelope when the consensus call is issued • Specification Usage • Review the HQMF To Procedural Translator UML Model and provide comments • Volunteers needed to represent Sample Queries using revised HQMF models and schemas. • Volunteers requiring access to the code repository • Please sign up for a google account at http://code.google.com • Project Repository - http://code.google.com/p/query-health/ • Sign up for the RI at http://wiki.siframework.org/Query+Health+Reference+Implementation
