CCOW standards have been touted to currently be the best way to integrate disparate clinical applications by passing user identification and passwords as well as patient context between these applications at the desktop. However, nothing has been published in academic journals on the actual realities of implementation of CCOW. In this report, we describe the implementation of CCOW for our three main clinical applications and compare this with the simultaneous development and implementation of a portal session manager for the same purpose. We found the portal session manager much easier to develop and implement than CCOW. The resulting functionality was almost equivalent as judged by our clinical end users who compared both solutions. We now have the portal session manager functional across the institution and have stopped any further work on CCOW.
[Show abstract][Hide abstract] ABSTRACT: Healthcare and medical research in Germany are heading to more interconnected systems. New initiatives are funded by the German government to encourage the development of Integrated Research and Treatment Centers (IFB). Within an IFB new organizational structures and infrastructures for interdisciplinary, translational and trans-sectoral working relationship between existing rigid separated sectors are intended and needed. This paper describes how an IT-infrastructure of an IFB could look like, what major challenges have to be solved and what methods can be used to plan such a complex IT-infrastructure in the field of healthcare. By means of project management, system analyses, process models, 3LGM<sup>2</sup>-models and resource plans an appropriate concept with different views is created. This concept supports the information management in its enterprise architecture planning activities and implies a first step of implementing a connected healthcare and medical research platform.

[Show abstract][Hide abstract] ABSTRACT: The integration of medical information is an important way to solve problems of information island and further data mining. Classical system analyzing and design ways have not met the development of medical information and it is imperative to search for new methods of systems integration. So the healthcare integrating model of medical information system based on agent is presented in this paper. And then the effectiveness and practicability are discussed through example analysis.

[Show abstract][Hide abstract] ABSTRACT: Inter-institutional cooperation among physicians becomes increasingly important. Yet, it is unrealistic to assume that cooperation can be supported via a homogeneous system that is pre-installed in every organization. Instead, physicians will typically have their own autonomous systems that support internal processes. Traditional activity-oriented workflow models do not resolve inter-institutional integration challenges. The goal of the proposed solution is to provide information exchange between strict autonomous healthcare institutions, bridging the gap between primary and secondary care, following traditional paper-based working practice. In large-scale inter-institutional scenarios, it is necessary to decouple cooperation functionality from the existing applications. This thesis presents the alpha-Flow approach for distributed process management, which enables ad hoc cooperation via active electronic documents without the need to integrate local systems. The rationale behind separating content, decision support, and coordination work will be explained. A distributed case file, the alpha-Doc, is used to coordinate cooperating parties. Using this case file does not require any pre-installed system components, so genuine ad hoc information interchange is enabled. The case file contains both the distributed process schema in form of a collective therapy plan as well as arbitrary content documents that are shared among the cooperating parties. To illustrate the approach an inter-institutional use case is provided by cooperative breast-cancer treatment.
