Advances in Query Health Initiative: HIMSS Showcase and Future Directions

The Query Health initiative recently showcased significant advancements at the HIMSS conference. Two demonstrations were successfully presented at the ONC booth, highlighting distributed queries and data analytics. Special thanks to volunteers who made this possible. The presentations were well-received, generating media interest across various platforms. Future plans include a recorded demo, further integration with i2B2 and PopMedNet, and continuous updates on specifications like HQMF and QRDA for enhanced interoperability. Community engagement remains strong, paving the way for exciting pilot opportunities.

  4. HIMSS Updates • Query Health team presented two demonstrations at • ONC Booth • Interoperability Showcase • Special thanks to the volunteer members who made the demo successful • ( Mike Buck, Keith Boone, Marc Hadley, Rob Rosen, Mike Sullivan, Karen Pearson, Shawn Murphy, Jeff Klann) • Planning to record the demo and post it for the WG’s • Presentation posted at : http://wiki.siframework.org/Query+Health • Well attended and well received, did make a number of media news articles, blog posting and twitter feeds (Some of them are listed here) • http://www.healthdatamanagement.com/news/query-health-distributed-queries-data-analytics-analysis-44013-1.html • http://www.healthcareitnews.com/news/onc-test-population-health-standards-new-york • http://www.govhealthit.com/news/new-york-test-oncs-query-health-standards • http://siframeworkblog.wordpress.com/2012/02/13/query-health-a-big-step-forward/ • http://news.avancehealth.com/2012/02/query-health-distributed-population.html • http://govhealthit.com/news/query-health-demo-round-trip-himss12 • Strong support for the initiative, Community getting stronger, thanks to all of your contributions. • New people interested in contributing to the Initiative • New pilot opportunities being explored

  5. 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

  6. 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

  7. 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 • Discussion from Srinivas

  8. 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.

  9. IHE SVS Profile and Sample • HQMF Samples Referring to Value Sets (Posted in the RI Repository) • Data Criteria section: • <entry> • <localVariableName>HasDiabetes</localVariableName> • <observationCriteria><id extension="HasDiabetes" root="0"/> • <statusCode code="completed"/> • <value xsi:type="CD" valueSet="2.16.840.1.113883.3.464.1.37"/> • <definition> • <observationReferencemoodCode="DEF"><id extension="Problem" root="0"/></observationReference> • </definition> • </observationCriteria> • </entry>

  10. IHE SVS Value Set Example • Value Set sample • Link: SVS.xml posted on the Repository http://code.google.com/p/query-health

  11. 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 • 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
