Jan 11, 2007 Healthcare Services Specification Project Decision Support Service (DSS) Update for CDS TC Kensaku Kawamoto, Ph.D. Duke University kawam001@mc.duke.edu
Brief Review • Part of HL7-OMG Healthcare Services Specification Project (HSSP) • HL7 defines Service Functional Model (SFM) • OMG defines technical specification based on SFM • DSS functionality • Takes patient data as the input and returns patient-specific inferences as the output • Generates inferences using knowledge modules • HL7 DSS SFM adopted as DSTU in Sept 2006 cycle • Post-reconciliation tally: 51 aff., 2 neg. (96% aff.)
Discussion Today • Upcoming OMG Request for Proposals (RFP) for DSS • OMG RFP process • Review of DSS RFP draft • Future work on specification of semantic profiles • Potential process • Potential foci for specification
HSSP Process Goal: issue at 3/07 OMG meeting Identify standardization candidates Specify Service Functional Model (SFM) [defines functionality, interfaces, and semantics*] HL7 Process (~1.0 - 1.5 yrs) Adopt SFM as HL7 Draft Standard for Trial Use (DSTU) Issue OMG request for technical specifications Vendors generate common service interface specification OMG Process (~1.5 - 2.0 yrs) Technical service specification adopted as OMG standard Commercial service implementations available *Service semantics also specified in separately balloted semantic profiles
Review of DSS RFP Draft • Based on RLUS and EIS RFPs (approved by OMG board in December 2006) • Available on project wiki • http://hssp-dss.wikispaces.com/space/showimage/DSS+OMG+RFP%2C+v2006-12-19.doc
Future Work on Specifying Semantic Profiles • Potential Process • http://hssp-dss.wikispaces.com/space/showimage/Proposed+process+for+leveraging+HL7+v3+content+as+payloads+in+HSSP+services%2C+v2006-11-21.pdf • Potential Foci • Topics with existing HL7 domain content and community interest in using DSS approach • E.g., immunizations, clinical genomics • Other topics of interest to CDS community • E.g., basic medication decision support
Upcoming Timeline (Tentative) • Timeline for OMG process • March 2007: Issue OMG RFP for DSS • June 2007 (?): Letters of Intent due • Early 2008 (?): Initial submissions due • Timeline for specifying semantic profiles • Ongoing: identify topics amenable to standardized semantics and establish process for defining profiles
