- Medical terminologies such as those in the UMLS are never exhaustive and there is a constant need to enrich them, especially in terms of multilinguality. We present a methodology to acquire new French translations of English medical terms based on word alignment in a parallel corpus - i.e. pairing of corresponding words. We automatically collected a 27.7-million-word parallel, English-French corpus. Based on a first 1.3-million-word extract of this corpus, we detected 10,171 candidate French translations of English medical terms from MeSH and SNOMED, among which 3,807 are new translations of English MeSH terms

- Objective: To present a user-centred method for introducing ICT in health care organisations, taking factors that influence acceptance into account.Methods: User centred methods are used in combination with previous research regarding factors that affect user acceptance, in order to facilitate users' acceptance of new ICT tools.Results: A method is presented that supports the introduction of ICT in team work. The method consists of three major steps; (1) the start-up seminar, (2) end user education and (3) continuous follow-up during the deployment phase. Important results of the start-up seminar are documentation of the users' expectations, and an agreement of ground rules that supports both the social norm factor and the users' perceived behavioural control. Education and follow-up also improve perceived behavioural control, and by involving super users perceived usefulness and ease of use can be improved through subjective norm.Conclusion: Key factors in the deployment process are; user participation, end user experience and education, and continuous follow-up of the process.

Meeting the Challenges : The Role of Medical Informatics in an Ageing Society
- 2006

- The objective of this paper is to identify trends and new technological developments that appear due to an ageing society and to relate them to current research in the field of medical informatics. A survey of the current literature reveals that recent technological advances have been made in the fields of "telecare and home-monitoring", "smart homes and robotics" and "health information systems and knowledge management". Innovative technologies such as wearable devices, bio- and environmental sensors and mobile, humanoid robots do already exist and ambient assistant living environments arc being created for an ageing society. However, those technologies have to be adapted to older people's self-care processes and coping strategies, and to support new ways of healthcare delivery. Medical informatics can support this process by providing the necessary information infrastructure, contribute to standardisation, interoperability and security issues and provide modelling and simulation techniques for educational purposes. Research fields of increasing importance with regard to an ageing society arc, moreover, the fields of knowledge management, ubiquitous computing and human-computer interaction.

- Skin cancer is a spreading disease in the western world. Early detection and treatment are crucial for improving the patient survival rate. In this paper we present two algorithms for computer assisted diagnosis of melanomas. The first is the support vector machines algorithm, a state-of-the-art large margin classifier, which has shown remarkable performances on object recognition and categorization problems. The second method, spin glass-Markov random fields, combines results of statistical physics of spin glasses with Markov random fields. We compared the two approaches using color histograms as features. We benchmarked our methods with another algorithm presented in the literature, which uses a sophisticated segmentation technique and a set of features especially designed for melanoma recognition. To our knowledge, this algorithm represents the state of the art on skin lesions classification. We show with extensive experiments that the support vector machines approach outperforms the existing method and, on two classes out of three, it achieves performances comparable to those obtained by expert clinicians.

- Identifying high-risk breast cancer patients is vital both for clinicians and for patients. Some variables for identifying these patients such as tumor size are good candidates for fuzzification. In this study, Decision Tree Induction (DTI) has been applied to 3949 female breast cancer patients and crisp If-Then rules has been acquired from the resulting tree. After assigning membership functions for each variable in the crisp rules, they were converted into fuzzy rules and a mathematical model was constructed. One hundred randomly selected cases were examined by this model and compared with crisp rules predictions. The outcomes were examined by the area under the ROC curve (AUC). No significant difference was noticed between these two approaches for prediction of recurrence of breast cancer. By soft discretization of variables according to resulting rules from DTI, a predictive model, which is both more robust to noise and more comprehensible for clinicians, can be built.

- When care professionals from different organisations are involved in patient care, their different views on the care process may not be meaningfully integrated.Objective: To use visualisation and interaction design solutions addressing the specific demands of shared care in order to support a collaborative work process.Methods: Participatory design, comprising interdisciplinary seminar series with real users and iterative prototyping, was applied.Results: A set of interaction and visualisation design solutions to address care professionals' requirements in shared home care is presented, introducing support for identifying origin of information, holistic presentation of information, user group specific visualisation, avoiding cognitive overload, coordination of work and planning, and quick overviews. The design solutions are implemented in an integrated virtual health record system supporting cooperation and coordination in shared home care for the elderly. The described requirements are, however, generalized to comprise all shared care work.Conclusion: The presented design considerations allow healthcare professionals in different organizations to share patient data on mobile devices. Visualization and interaction design facilitates specific work situations and assists in handling specific demands in shared care. The user interface is adapted to different user groups with similar yet distinct needs. Consequently different views supporting cooperative work and presenting shared information in holistic overviews are developed.

- Free-text queries are natural entries into the exploration of complex terminology systems. The way search results are presented has impact on the users ability to grasp the overall structure of the system. Complex hierarchies like the one used in SNOMED CT, where nodes have multiple parents (IS-A) and several other relationship types, makes visualization challenging. This paper presents a prototype, Term Viz, applying well known methods like "focus+context" and self-organizing layouts from the fields of Information Visualization and Graph Drawing to terminologies like SNOMED CT and ICD-10. The user can simultaneously focus on several nodes in the terminologies and then use interactive animated graph navigation and semantic zooming to further explore the terminology systems without loosing context. The prototype, based on Open Source Java components, demonstrates how a number of Information Visualisation methods can aid the exploration of medical terminologies with millions of elements and can serve as a base for further development.
