The document discusses the challenges of creating a web of clinical knowledge, emphasizing the need for standards to facilitate the sharing and processing of healthcare information. It highlights the efforts of the DODTAPS research project to convert clinical content into RDF format and improve interoperability through technologies like FHIR. The document calls for community engagement to further develop and expose reusable clinical knowledge.

- 1. Towards a Web of Clinical Knowledge Experience gained from DoDTAPS Research Project Claude Nanjo December 2014 SemanticWeb.com
- 2. Overview •The healthcare challenge •Exposing clinical knowledge on the Web as RDF •Transforming clinical content –An example from the DoDTAPS project •Getting closer to this vision
- 3. The Challenge The US Healthcare System is highly heterogeneous. How do we converge?
- 4. The Rapid Growth of Health Knowledge Information will need to be sharable and machine-processableif it is to scale

- 18. Why we need standards to guide clinical capture •RDF makes the processing of clinical information staight-forward. –Lots of tooling –It is a known semantic model with a number of supported representations (RDF/XML, Turtle, …) •RDF cannot solve all problems –Transformations are expensive even with RDF –Hard to maintain –Transformations are lossyand not always deterministic •Need standards to converge on –Standards that allows convergence towards a common clinical baseline. –Great strides being made in the standards world –Customization and localization increase TCO
- 19. A few encouraging developments •The adoption of FHIR (Fast Healthcare Interoperability Resources) –an implementer-friendly resource-oriented, REST-based clinical resource framework –http://www.hl7.org/implement/standards/fhir/summary.html •The RDF Semantic Interoperability SWG at HL7 –Goal: To help expose HL7 standards using OWL/RDF –Discussion on an OWL ontology for FHIR and a FHIR RDF representation •Convergence of two existing communities –HL7 –W3C Semantic Web for Health Care and Life Sciences Group –http://wiki.hl7.org/index.php?title=RDF_for_Semantic_Interoperability

- 23. Encouraging developments •ONC’s Clinical Quality Framework Initiative –The harmonization of CDS and Clinical Quality models through FHIR –CDS ontologies? •CDS Collaborative –Collaboration between the University of Utah (OpenCDS) and Cognitive Medical Systems (Socratic Grid) –Declarative rules to be exposed on the Web –Enable access to clinical decision support services that leverage the web and RDF
