A reference model for clinical tumour documentation.

The definition of common system semantics is an explicit and generally accepted precondition for comparability and exchangeability of data from different systems. We have looked back on 15 years of experience with a data model that was developed in a co-operative effort by experts from various hospital cancer registries as the foundation of a new tumour documentation system (GTDS). The data model is based on the definition of a common basic data set for hospital cancer registries which is agreed by the German Association of Comprehensive Cancer Centres (ADT). This paper presents an "entity relationship" view of this model. Since data exchange among registries and with hospital or practice information systems is becoming increasingly important we describe our method to import data from such systems. We discuss the requirements that systems have to have for a most effective way of exchanging data with a hospital cancer registry. The most important feature is the possibility to associate disease phenomena and therapies with each other and with an entity that represents the tumour across encounters. The reference model we present respectively the requirements we propose for other communicating systems might also fit for other chronic diseases.

Representation of medical informatics in the wikipedia and its perspectives.

A wiki is a technique for collaborative development of documents on the web. The Wikipedia is a comprehensive free online encyclopaedia based on this technique which has gained increasing popularity and quality. This paper's work explored the representation of Medical Informatics in the Wikipedia by a search of specific and less specific terms used in Medical Informatics and shows the potential uses of wikis and the Wikipedia for the specialty. Test entries into the Wikipedia showed that the practical use of the so-called WikiMedia software is convenient. Yet Medical Informatics is not represented sufficiently since a number of important topics is missing. The Medical Informatics communities should consider a more systematic use of these techniques for disseminating knowledge about the specialty for the public as well as for internal and educational purposes.

XML-based application interface services--a method to enhance integrability of disease specific systems.

Disease specific systems usually offer excellent functionality for the management of the covered diseases. But the restriction to a certain disease often hampers their wide spread use since they are not optimised for clinical workflow. The Giessener Tumordokumentationssystem (GTDS) is a disease specific system that is not only designed for the use in tumour registries but also to support clinical care. In order to integrate it into hospital information systems, we implemented standard communication interfaces. However, interfaces are not satisfactory since they do not consider aspects of the normal workflow of a clinical user. Therefore, we developed a strategy that should ease the access to the system in the environment of existing systems. From the technical point of view, XML with its capabilities to represent even complex data in a rather simple way helped to implement this strategy. We use XML to communicate with API-like services and created a WWW environment to demonstrate the access to these services. Since HTML based access itself is a means to integrate systems, we intend to expand this environment to an appropriate region based means to improve the communication with registries. Another application using the services is the transfer of data between two registries with common patients.

Plug-and-play XML: a health care perspective.

The application of XML (Extensible Markup Language) is still costly. The authors present an approach to ease the development of XML applications. They have developed a Web-based framework that combines existing XML resources into a comprehensive XML application. The XML framework is model-driven, i.e., the authors primarily design XML document models (XML schema, document type definition), and users can enter, search, and view related XML documents using a Web browser. The XML model itself is flexible and might be composed of existing model standards. The second part of the paper relates the approach of the authors to some problems frequently encountered in the clinical documentation process.
