Workshop on semantic interoperability prerequisites for efficient e-health systems. How to support convergence of ontology, standards in health informatics for clinical terminologies,classifications, coding systems and e health records. A strategy for a top down approach Brussels 14-15/02/05 Jean marie Rodrigues rodrigues@univ-st-etienne.fr
WHY A TOP TOP DOWN APPROACH 1 BETWEEN 2 OPPOSITE POSSIBLE ERRORS 11 11 IDEAL SOLUTIONS No No chances before we we are are all all dead dead 12 12 PRAGMATIC RESIGNATION So So difficult let let us us go go our our old old traditional way way (ex (ex procedures coding systems) 2 DIVERGENT BOTTOM UP UP INITIATIVES See See before 3 SEMANTIC INTEROPERABILITY PERCEIVED AS AS A RISING PRIORITY BUT BUT 31 31 No No clear understanding by by decision makers 32 32 Underestimation of of the the complexity of of the the whole and and of of some parts 33 33 Mixing not not optimal between industry and and academic
WHERE WE WE ARE The The different aspects of of interoperability (Electronic Health Records, messages, security, terminology and and languages, data data types, information models, architectures, archetypes, standards,etc.) are are addressed by by divergent initiatives aiming at at exchanging not not only only data data or or information, but but also also at at transferring meaning: in in healthcare, such a practice is is related to to risk. risk.
WHERE WE WE ARE Advanced technologies in in computer and and other disciplines, such as as artificial intelligence, allow for for much more complex problems solving in in routine: this this is is possible through the the use use of of such tools as as ontologies and and formal representations, hidden within the the computer for for terminology, or or personal microprocessor cards for for security.
