    IHE based Interoperability for Service Oriented Architectures
    (INFORMATIK 2008. Beherrschbare Systeme – dank Informatik. Band 1, 2008) Wozak, Florian; Ammenwerth, Elske; Hörbst, Alexander; Sögner, Peter; Mair, Richard; Schabetsberger, Thomas
    Optimized workflows and communication between institutions involved in a patient’s treatment process can lead to improved quality and efficiency in the healthcare sector. Electronic Health Records (EHRs) provide a patient–centered access to clinical data across institutional boundaries supporting the above mentioned aspects. Interoperability is regarded as vital success factor. However a clear definition of interoperability does not exist. The aim of this work is to define and to assess interoperability criteria as required for EHRs. Methods: The definition and assessment of interoperability criteria is supported by the analysis of existing literature and personal experience as well as by discussions with several domain experts. Results: Criteria for interoperability addresses the following aspects: Interfaces, Semantics, Legal and organizational aspects and Security. The Integrating the Healthcare Enterprises initiative (IHE) profiles make a major contribution to these aspects, but they also arise new problems. Flexibility for adoption to different organizational/regional or other specific conditions is missing. Regional or national initiatives should get a possibility to realize their specific needs within the boundaries of IHE profiles. Security so far is an optional element which is one of IHE greatest omissions. An integrated security approach seems to be preferable. Discussion: Irrespective of the so far practical significance of the IHE profiles it appears to be of great importance, that the profiles are constantly checked against practical experiences and are continuously adapted.

    Meeting EHR security requirements: authentication as a security service
    (perspeGKtive 2010. Workshop „Innovative und sichere Informationstechnologie für das Gesundheitswesen von morgen“, 2010) Katt, Basel; Trojer, Thomas; Breu, Ruth; Schabetsberger, Thomas; Wozak, Florian
    Electronic Health Record (EHR) is a promising concept to collect and manage electronic health information of all citizens. Integration the Heathcare Enterprise (IHE) was one of the first initiatives that aims at standardizing the way healthcare systems exchanging information in a distributed environment. Based on EHR concepts and IHE profiles different approaches have been introduced in the industry and the literature to implement and apply solutions for different stakeholders in the healthcare domain (see e.g., http://www.ith-icoserve.com/). Due to the sensitivity of the data dealt with in these systems, security is a major concern that must be considered. In previous work we have presented a general architectural solution to apply the evolving Security as a Service (SeAAS) paradigm in distributed architectures for EHR in conformance to IHE-proposed profiles. While our architecture proposed is generic and covers all security requirements, we focus in this work on one security requirement, namely, authentication and show how it can be offered as a service while adhering to IHE profiles.1
