Opportunity New generation of clinical systems beyond efficient record storage and communication –New paradigm with pervasive computerized data analysis and decision support –Widespread use of interoperable services and data, with advanced functions that enable team-based care

Example: Simple ‘If - Then’ rule 4

Patient data ConceptsKnowledge LOINC? Problem list? Coded values? SNOMED CT? Bedside measurements? Lab results? Medications? Rules? Formulas? Classifications?

Availability of data Availability of structured and coded clinical data determines the feasibility of CDS interventions –Data is expensive to generate at the point-of-care (systematically) –Benefits frequently not tangible to data “producers” (extra incentives) Dissemination and exchange of knowledge assets depends on data standardization (structure & semantics) Health IT Data Standards! Natural language processing? Voice recognition? Mobile devices? Knowledge-driven documentation? Semantic expressivity (adaptive)?

Efficient dissemination strategy Stead WW and Lin HS, editors. Computational Technology for Effective Health Care: Immediate Steps and Strategic Directions. National Research Council, Similar model for a Personal Health Records (individuals)

Current dissemination barriers Large scale CDS What will differentiate clinical systems? Process automation? Ease of use? Advanced CDS functions?

How ontologies can help? Shared concepts and logical models (data & knowledge) –Proper domain coverage, but without compromising extensibility and innovation –More accessible methods and tools to enable widespread adoption –Training and demonstration projects Cost-effective semantic interoperability –Lower the cost and overhead of the data & knowledge ‘translation’ every time exchange is necessary Clinical systems that can seamlessly represent and process a complete electronic patient care record –Move beyond interoperability space and start influencing/guiding transactional data and knowledge representation models
