Konferensbidrag (refereegranskat)abstract
- In a net-based society, clinicians can come together for cooperative work and distance learning around a common medical material. This requires suitable techniques for cooperative knowledge management and user interfaces that are adapted to both the group as a whole and to individuals. To support distributed management and sharing of clinical knowledge, we propose the development of an intelligent web community for clinicians within oral medicine. This virtual meeting place will support the ongoing work on developing a digital knowledge base, providing a foundation for a more evidence-based oral medicine. The presented system is founded on the use and development of web services and standards for knowledge modelling and knowledge-based systems. The work is conducted within the frame of a well-established cooperation between oral medicine and computer science.

Konferensbidrag (refereegranskat)abstract
- Medical ontologies like GALEN, the FMA or SNOMED represent a kind of “100% certain” medical knowledge which is not inherent to all medical sub-domains. Clinical radiology uses computerized imaging techniques to make the human body visible and interprets the imaging findings in a clinical context delivering a textual report. For clinical radiology few standardized vocabularies are available. We examined the definitions given in the glossary of terms for thoracic radiology published by the Fleischner Society. We further classified these terms with regard to their definitions in terms of (a) describing visible structures on the image itself, (b) referring to ontological entities of the body (anatomical or pathological), and (c) terms imposing knowledge on structures visible on the image, epistemologically representing ontological entities of the body. Each ontological/epistemological definition was rated on a scale of vague/weak-sound/strong and put in context with the evaluation comments for the use of the terms given in the glossary itself. The result of this distinction shows that clinical radiology uses many terms referring to ontological entities valid for representation in a medical ontology. However, many epistemological terms exist in the terminology which impose epistemological knowledge on ontological entities. The analysis of the evaluation comments reveals that terms classified as sound (ontologically) and strong (epistemologically) are evaluated higher than terms bearing vague or weak definitions. On the basis of this, we argue that the distinction between ontological and epistemological definitions is necessary in order to construct epistemologically-sensitive application ontologies for medical sub-domains, like clinical radiology, where knowledge is fragmented in terms of description, inferred from a description, concluded on the basis of imaging, or other additional information with varying degrees of certainty.

Bokkapitel (refereegranskat)abstract
- The coexistence of different information systems that are unable to communicate with each other is a persistent problem in health care in general, and in shared care in particular. This is especially critical when it comes to information access needed at the point of care, e.g. in the patients home. The purpose of this paper is to present the technical architecture of a virtual health record (VHR) that both integrates information from different electronic health records (EHRs) and allows for documenting at the point of care using mobile devices. The VHR supports a seamless information and communication flow between different care providers giving them mobile access to selected patient-oriented information. A service oriented system architecture where database functionality and services are separated has been implemented. This guarantees flexibility with regard to changed functional demands and allows third party systems to interact with the platform in a standardised way. Major requirements for the VHR have been documentation support at the point of care, integrated presentation of the information from different feeder systems, and the possibility of offline access to the data on handheld devices. Therefore, publishing was chosen for the integration design. A patient centred XML schema is published as an interface for integration with the information broker. The feeder systems deliver their information in XML.-files that are mapped against the ideal schema and inserted into the mediator database. The paper describes both an online web application and an offline solution that was implemented on personal digital assistants (PDAs). The system has been introduced in a Swedish home care district with an established fiber-optical network infrastructure connecting all the locations forming the study site.
