  1. Impact of ontologies in healthcare and biomedical researchImpacto de las ontologías en la asistencia y en la investigación biomédica Ronald Cornet, PhD Dept of Medical Informatics, AMCDept of Biomedical Engineering, Linköping Univ

  2. What is an Little agreement… • “Strict” definition • a specification of a conceptualization • “Loose” definition • a model for describing the world that consists of a set of types, properties, and relationship types

  3. Whyontologies?

  4. 1. Fromlanguageto meaning • Language is ambiguous;homonyms • DRE = DilatedRetinalExamination • DRE = Digital RectalExamination • #HOF?= ??? • Synonymshidesimilarmeaning • Heartattack • Myocardial infarct

  5. 2. Levels of abstraction • Bridging generic and specificconcepts • Guidelines mayrefer to“cardiorespiratory disorder” • Patient records containspecific diagnoses, e.g.,COPD • Is COPD a cardiorespiratorydisorder?

  6. 3. Query byrelationships • No fixed ordering necessary • Lung tumor: site=lung; morph=tumor • Lung infection: site=lung; process=infection • Brain tumor: site=brain; morph=tumor • Brain infection: site=brain; process=infection • Querying by site, morphology or process

  7. Impact in healthcare (&) research Currentprocess Health data

  8. Gartner Research CDR = clinical data repository CDS = clinical decision support CMV = controlled medical vocabulary CPOE = computer-based physician order entry KM = knowledge management WF = workflow framework

  9. Controlled Medical Vocabulary≈Ontology

  10. 5 generations of Electronic Patient Records (Gartner, June 2007)

  11. Gartner Hype Cycle for Healthcare Provider Applicationsand Systems, 2012

  12. Examplesfor healthcare

  13. Conclusion • Ontologies are key to (re)usable data • Third+-generation records • Level 2+ healthcare analytics • Evidence-based medicine& • Medicine-basedevidence
