  1. Towards a Flexible Integration of Clinical Guideline Systems With Medical Ontologies and Medical Information Systems Gianluca Correndo1, Paolo Terenziani2 1DI, Università di Torino, Corso Svizzera 184, 10149 Torino, Italy 2DI, Univ. Piemonte Orientale “A. Avogadro”, Spalto Marengo 33, Alessandria, Italy

  2. Outline • Need for data integration • Knowledge Sharing • Guideline standardization • External ontology integration • GLARE proposal • Translation Services • Comparisons

  3. Need for Data Integration Clinical Guideline GLARE Execution Environment Patients’ Data DB If ECG is altered for patient then … SELECT exam FROM … WHERE …

  4. b a Knowledge Sharing • a) Centralized View: • One Ontology • Every IS adheres to it • b) Decentralized View: • Different Ontologies • Every IS particularize its data access in order to adhere to the choosed ontology

  5. Guidelines Standardization Different Standard Vocabularies GLARE Different IS SNOMED UMLS ICD-9 . . .

  6. Domain Ontology #1 DB Ontology Mapping #1 Domain Ontology #2 Mapping #2 DB External Ontology Integration General DB concepts Particular DB description

  7. Knowledge Sharing Information System a Information System b Personal DB Ontology a b SNOMED UMLS ICD-9

  8. GLAREs’ Proposal System KIS User Physician Expert Physician Browser Module Metadata Acquisition Interface Execution Interface DB Ontology Medical Ontology Mapping Extraction Module Query Compiler Acquisition Execution XML XML XML DBMS Instance DB CGL DB Clinical DB Patient DB
