©2010, Kensaku Kawamoto Presentation Overview  Problem Need for scalable clinical decision support (CDS)  Potential Solution Standards-based, open-source CDS services  OpenCDS  Discussion

©2010, Kensaku Kawamoto The Problem  Despite demonstrated effectiveness, CDS is not widely available  The lack of CDS availability is due in part to the tight coupling of CDS capabilities with specific institutions and health IT systems

©2010, Kensaku Kawamoto The Need  Application-independent CDS resources that can be efficiently leveraged by diverse healthcare systems and health IT settings to improve patient health

©2010, Kensaku Kawamoto Presentation Overview  Problem Need for scalable clinical decision support (CDS)  Potential Solution Standards-based, open-source CDS services  OpenCDS  Discussion

©2010, Kensaku Kawamoto Rationale for Open, Standards-Based CDS Services  Why CDS services? Encapsulates knowledge in highly reusable components Supports multiple knowledge representation approaches Validated by several groups, including users of SEBASTIAN CDS service (see panel in next session)  Why standards-based? To enable interoperability and scalability  Why open source? To foster adoption and collaboration

©2010, Kensaku Kawamoto OpenCDS  Goal Facilitate widespread availability of advanced CDS capabilities through open-source, collaborative development of standards-based DSS infrastructure, tooling, and high-value services  Methods Contribute through Open Health Tools Leverage open-source JBoss Drools rules engine Use modular architecture, enable iterative refinement, support multiple knowledge represent. approaches Develop all components required to author, test, and operationally support standards-compliant DSSs  Goal Facilitate widespread availability of advanced CDS capabilities through open-source, collaborative development of standards-based DSS infrastructure, tooling, and high-value services  Methods Contribute through Open Health Tools Leverage open-source JBoss Drools rules engine Use modular architecture, enable iterative refinement, support multiple knowledge represent. approaches Develop all components required to author, test, and operationally support standards-compliant DSSs

©2010, Kensaku Kawamoto Key Components  Standard interfaces and data models Reference implementation of HL7/OMG DSS interface vMR data model Data mappers (e.g., for CCD  vMR)  Reference DSS knowledge management framework JBoss Drools and associated authoring/knowledge management tools Full-featured terminology support A “domain specific language” for intuitive knowledge authoring  DSS “wrappers” for other CDS engines  Standard interfaces and data models Reference implementation of HL7/OMG DSS interface vMR data model Data mappers (e.g., for CCD  vMR)  Reference DSS knowledge management framework JBoss Drools and associated authoring/knowledge management tools Full-featured terminology support A “domain specific language” for intuitive knowledge authoring  DSS “wrappers” for other CDS engines

©2010, Kensaku Kawamoto Presentation Overview  Problem Need for scalable clinical decision support (CDS)  Potential Solution Standards-based, open-source CDS services  OpenCDS  Discussion

©2010, Kensaku Kawamoto Key Benefits of Approach  Builds on robust open-source community and resources  Provides standard architectural framework for integrating various CDS knowledge resources  Supports full life cycle of knowledge authoring, testing, maintenance, and execution  Provides an open-source framework for collaboration and innovation in CDS

©2010, Kensaku Kawamoto Key Challenges and Potential Solutions ChallengePotential solutions Increased effort required to develop and support knowledge resources for use in multiple contexts  Balance generalizability with resource realities  Spread knowledge development cost over multiple deployment settings  Bottom line assessment: benefits >> challenges Limited content availability  Provide federal funding for content development  Create an interoperable, standards-based market for such knowledge
