Abstract [en]

This paper relates a study of reliability of coding of surgical procedures in the domain of thoracic surgery. The reliability measured is inter-coder variability in form of agreement. Four classifications were used by four physicians on 100 patient cases. The classifications, having differing granularity and structure, were analyzed using a statistical method (kappa). These results are discussed and related to the differences between the classifications. One of the topics for discussion is how the granularity affects the degree of agreement, coupled to the usefulness of the classification. Also the concept of using formal methods for representing classifications is discussed, how this will affect how classifications are designed and used.

Abstract [en]

Classifications, terminology and terminology services are important in the field of medical informatics. They are needed when building applications such as Computer based Patient Record systems (CPRs). Even though many classifications, nomenclatures and terminology systems have been constructed to this end, e .g. ICD, MeSH and SNOMED, no single system has, so far, covered medicine in its entirety. Several of the aforementioned constructs have grown to the extent that manual maintenance can no longer cope, thus computer based tools are needed for this task.

The main objective of this thesis is to present some computer based terminology tools that have been constructed to facilitate part of the work of building sound terminologies and application systems. The usefulness of such terminologies, terminology tools as well as the importance of being able to integrate the terminology have been reviewed and are discussed. Moreover tools (from GALEN) for maintenance and developme nt of classilications are evaluated.

Two terminology tools are presented that aim to facilitate the access to and the use of terminology and terminology services. One tool is built on a proposal for a concept oriented Swedish national terminology data base model (Spriterm). The other tool is a dedicated client (KOMANTIS) to the GALEN terminology server (TeS) developed as a deliverable within the European GALEN project. It will facilitate the integration of terminologies between the information system and the knowledge base when building Decision Support Systems (DSS).
