Concept to Codes

• Last week– Discussion of 4 high level next steps and alignment to CEDD

and Technical Workgroups– Discussion of Key Themes– Introduced the integration points of C2C within the Technical

Expression

• Agenda for 3/6 – – i2B2 Walkthrough

• Discuss how ontologies are represented, where they come from and how it gets used to compose Queries.

– IHE Shared Value Sets (SVS) • Discuss how it applies to Query Composition Standard (HQMF)• What does the standard provide? How can it be used in the

Technical Framework?7

Query Health CEDD Timeline

• Review Query Health CEDD Specification – finalized implementation model alignment (i2b2 (PCIP), PopMedNet (ESP and Mini-Sentinel), and hQuery)– Version 0.2 specification posted to the wiki, and comments being

dispositioned: http://wiki.siframework.org/Query+Health+CEDD+Comments

– Finalize work with Clinical WG Volunteers to capture clinical examples to assist implementers

– Working through additional crosswalk revisions, as shown here: https://docs.google.com/spreadsheet/ccc?key=0ApW4Ox66ml2IdEtYR0lwenlJVWl6RC1vVnZuaEppeWc

– Additional meetings over next 2 weeks to finalize specification for initial consensus

Operations Workgroup Activities and Next Steps

Work Accomplished• Resolved “No” vote with Community member regarding DUA• Created new language to address concerns around the “Destruction

of Data” clause in existing version of DUA• Started Risk Analysis of Technical Approach

Next Steps• Review new “Destruction of Data” clause with workgroup• Continue Risk Analysis of Technical Approach

Pilots Team Activities and Next Steps

Work Accomplished• Continued outreach to vendors and potential pilots

Update from NYC/NYS

Next Steps• Ongoing communication with other potential pilot organizations

Technical Working Group

March 6, 2012

RI Update• RI Repository Link: http://code.google.com/p/query-health• PopMedNet

• Plugin Implementation on the Portal side completed.• http://wiki.siframework.org/Query+Health+Reference+Implementation

• Staging site setup in the cloud owned by Lincoln Peak for testing plug-ins • Release planning currently underway to determine the best time to release this version to the open

source – Mid March timeframe• i2B2

• Design document done, going through internal i2B2 reviews.• Expect to review the document soon.• Next Steps: Integration of PopMedNet – i2B2 is being planned based on the design document.

• hQuery • hQuery Integration with PopMedNet complete• Able to go round trip from query composition to execution and viewing of results• Need to continue testing and improving the integration

• Translators• Keith Boone posted first version of translator for i2B2 XML to HQMF• Marc Hadley and Team working on the HQMF to Java Script converter for execution by hQuery

Gateway

Specification Updates• HQMF

• IG document in progress and hope to review soon.• Draft posted: http://wiki.siframework.org/Query+Health+-+Query+Format

• Query Catalog for sample query representation and validation posted on wiki• Draft posted: http://wiki.siframework.org/Query+Health+-+Query+Format• Need volunteers to fill this out, one query at a time

• Query Envelope• Draft Specification posted

• http://wiki.siframework.org/Query+Health+-+Query+Envelope• Updated Transport / Authentication / Authorization requirements

• CEDD• Draft Specification posted:

• http://wiki.siframework.org/Query+Health+Clinical+Element+Data+Dictionary+%28CEDD%29

QRDA Updates• QRDA

• IG document in progress and hope to review soon.• Draft posted: http://wiki.siframework.org/Query+Health+-+Query+Result

• Srinivas has represented NQF 59 results and is posted on the wiki.• Highlights of the discussion

• Add Business Names• Represent Category II• Link back to HQMF• Need to retain Category I as is• Need to decide on Measure Set / Measure Section etc.

IHE SVS Profile• http://

www.ihe.net/Technical_Framework/upload/IHE_ITI_Suppl_SVS_Rev2-1_TI_2010-08-10.pdf• Trial implementation standard• SVS defines the transmission protocols for a network access to a terminology server

focused specifically on the distribution of Value Sets. 320• Why are we discussing this ?

• Queries in HQMF use value sets either inline or as an external link to a value set• Sharing Value Sets (SVS) becomes very important in this regard.• Should we standardize around this and make it part of our recommended technical

standards ?• Protocol for the Consumer

• Consumer side: Simple HTTP based protocol cane be used to retrieve the value set information

• Use a simple HTTP GET in a RESTful manner• SOAP option also exists.

Next Steps

• Specification Reviews• Review Query Envelope / CEDD / HQMF / QRDA Specification and post comments.

• Specification Usage• Volunteers needed to represent Sample Queries using revised HQMF models and

schemas.• Volunteers requiring access to the code repository

Important Announcements

• Additional community support for reference implementation development continues to be encouraged• HQMF and QRDA representation support for NQF measures• Sample Query Catalog review• CEDD specification review

• Face to Face meeting coming up in April• Focus on technical approach
