- The development of information and communication technology (ICT) for citizen-centered care requires insight into concrete problems in care processes as well as an understanding of the goals and values that should guide these. In this retrospective study we return to results from two research projects focusing on the needs of senior citizens and stroke patients. We describe the intersections between health care services, social care services and private services, and analyze these with focus on the needs of independence, continuity and participation. The current state of ICT in relation to the identified needs is also addressed. In conclusion, an increasing number of solutions are available to support senior citizens in different parts of their lives, yet they remain isolated and have limited impact. In order to harness value for senior citizens, it is imperative to continue with multidisciplinary research focusing on socio-technical aspects; addressing technological, organizational, legal and business-related aspects.

Knowledge Artifacts as Tools to Communicate and Develop Knowledge in Collaborative User-Driven Design
- 2012
-
In: 25th IEEE International Symposium on Computer-Based Medical Systems (CBMS 2012). - : IEEE Computer Society. - 9781467320511 ; , s. 210-215

Conference paper (peer-reviewed)abstract
- We investigate an ongoing user-driven collaborative knowledge engineering and interaction design process. The anticipated outcomes are knowledge-based support applications for health care professionals and other actors in the dementia domain.The two major goals for the activity in focus are: 1) to accomplish international collaboration across organizational, language and professional boundaries in the modeling of knowledge and design of interaction, and 2) in a local community provide ICT support for collaboration and communication between organizations, increase knowledge development in individual actors and increase the quality of dementia care. The semantic web-based prototype system ACKTUS is introduced as a tool for modeling and communicating knowledge and interaction, and its role in the process is evaluated. The activity is organized as a part of a collaborative work between different organizations to develop their local clinical practice. Obstacles and success factors when enabling the endusers to design their own tools are detected and discussed.

Argumentation Theory in Health Care
- 2012
-
In: 2012 25th IEEE International Symposium on Computer-Based Medical Systems (CBMS). - New York, NY, USA : IEEE. - 9781467320498 - 9781467320511 ; , s. 1-6

Conference paper (peer-reviewed)abstract
- Argumentation theory (AT) has been gaining momentum in the health care arena thanks to its intuitive and modular way of aggregating clinical evidence and taking rational decisions. The basic principles of argumentation theory are described and demonstrated in the breast cancer recurrence problem. It is shown how to represent available clinical evidence in arguments, how to define defeat relations among them and how to create a formal argumentation framework. Argumentation semantics are then applied over the built framework to compute arguments justification status. It is demonstrated how this process can enhance the clinician decision-making process. A encouraging predictive capacity is compared against the accuracy rate of well-established machine learning techniques confirming the potential of argumentation theory in health care.

A novel Bayesian approach to adaptive mean shift segmentation of brain images
- 2012
-
In: Proceedings - IEEE Symposium on Computer-Based Medical Systems. - 1063-7125. - 9781467320511

Conference paper (peer-reviewed)abstract
- We present a novel adaptive mean shift (AMS) algorithm for the segmentation of tissues in magnetic resonance (MR) brain images. In particular we introduce a novel Bayesian approach for the estimation of the adaptive kernel bandwidth and investigate its impact on segmentation accuracy. We studied the three class problem where the brain tissues are segmented into white matter, gray matter and cerebrospinal fluid. The segmentation experiments were performed on both multi-modal simulated and real patient T1-weighted MR volumes with different noise characteristics and spatial inhomogeneities. The performance of the algorithm was evaluated relative to several competing methods using real and synthetic data. Our results demonstrate the efficacy of the proposed algorithm and that it can outperform competing methods, especially when the noise and spatial intensity inhomogeneities are high.

Supporting clinical trials to predict adverse events in the brain trauma domain
- 2012
-
In: IEEE Symposium on Computer-Based Medical Systems. - 9781467320511 ; , s. 6266380-
-
Conference paper (peer-reviewed)abstract
- There are many serious and acute physiological conditions about which we have incomplete medical knowledge. To address this and develop effective treatments it is often the case that a wealth of clinical data is required for collection, analysis and feedback. Whilst such data often exists it is typically held in a variety of different formats and locations. This paper describes the EU FP7-funded Avert-IT project (www.avert-it.org), which has developed an integrated, real-time physiological data infrastructure (ICUnet) to address the specific issue of prediction of hypotensive events in the brain trauma domain. This system has been used to support a major multi-centre clinical trial. In this paper, the implementation and application of the ICUnet system is described, followed by the design and results of the clinical trial.
