Towards Interoperability in E-health Systems: a three-dimensional approach based on standards and semantics

Proceedings of: HEALTHINF 2009 (International Conference on Helath Informatics), Porto (Portugal), January 14-17, 2009, is part of BIOSTEC (Intemational Joint Conference on Biomedical Engineering Systems and Technologies)The interoperability problem in eHealth can only be addressed by mean of combining standards and technology. However, these alone do not suffice. An appropiate framework that articulates such combination is required. In this paper, we adopt a three-dimensional (information, conference and inference) approach for such framework, based on OWL as formal language for terminological and ontological health resources, SNOMED CT as lexical backbone for all such resources, and the standard CEN 13606 for representing EHRs. Based on tha framewok, we propose a novel form for creating and supporting networks of clinical terminologies. Additionally, we propose a number of software modules to semantically process and exploit EHRs, including NLP-based search and inference, wich can support medical applications in heterogeneous and distributed eHealth systems.This work has been funded as part of the Spanish nationally funded projects ISSE (FIT-350300-2007-75) and CISEP (FIT-350301-2007-18).

Adaptation driven change management

In solving the global obesity epidemic the realization has come that it is mainly an issue of behavioral change. Benefits have been shown in personalizing the information that induces these changes. At the same time obesity is a heavily researched field in which new discoveries are made every day. This brings the need for maintainability of these personalized information channels. In this paper we propose architecture for a maintainable system for the provision of tailored documents for obesity patients
