Abstrakt

Exchange and re-use of data and information is key when seeking semantic interoperability across heterogeneous EHRs. In eHealth communities there is a great focus on designing and implementing interoperable and useful EHRs. Furthermore, a focus on development of comprehensive terminology systems to achieve a common description of clinical concepts exists. However, these efforts are done in parallel and unknown pitfalls surface when integrating massive systems. The objective of this paper addresses the role of terminology systems and EHRs when seeking semantic interoperability across heterogeneous EHRs. We highlight pitfalls and the consequences of these. The methodology used consists of a review of the scientific literature on EHRs and terminology systems followed by a workshop with practitioners conformed to the result of the review. The results indicate one major pitfall: ambiguity. This pitfall has more facets; both multiple mappings and semantic ambiguity. A severe consequence of these can be misinterpretation of meaning and intend with a given concept.
