Towards pervasive computing in health care – A literature review

Carsten Orwat; Andreas Graefe; Timm Faulwasser

BackgroundThe evolving concepts of pervasive computing, ubiquitous computing and ambient intelligence are increasingly influencing health care and medicine. Summarizing published research, this literature review provides an overview of recent developments and implementations of pervasive computing systems in health care. It also highlights some of the experiences reported in deployment processes.MethodsThere is no clear definition of pervasive computing in the current literature. Thus specific inclusion criteria for selecting articles about relevant systems were developed. Searches were conducted in four scientific databases alongside manual journal searches for the period of 2002 to 2006. Articles included present prototypes, case studies and pilot studies, clinical trials and systems that are already in routine use.ResultsThe searches identified 69 articles describing 67 different systems. In a quantitative analysis, these systems were categorized into project status, health care settings, user groups, improvement aims, and systems features (i.e., component types, data gathering, data transmission, systems functions). The focus is on the types of systems implemented, their frequency of occurrence and their characteristics. Qualitative analyses were performed of deployment issues, such as organizational and personnel issues, privacy and security issues, and financial issues. This paper provides a comprehensive access to the literature of the emerging field by addressing specific topics of application settings, systems features, and deployment experiences.ConclusionBoth an overview and an analysis of the literature on a broad and heterogeneous range of systems are provided. Most systems are described in their prototype stages. Deployment issues, such as implications on organization or personnel, privacy concerns, or financial issues are mentioned rarely, though their solution is regarded as decisive in transferring promising systems to a stage of regular operation. There is a need for further research on the deployment of pervasive computing systems, including clinical studies, economic and social analyses, user studies, etc.

This paper discusses three crucial factors for the adoption of pervasive computing in healthcare: proof of medical benefit, user participation, and financial clarification. This system could also differentiate healthy from unhealthy people by measuring the participants step amplitude and velocity.

ZusammenfassungSoftware regelt immer mehr zwischenmenschliche Interaktionen. Üblicherweise werden die Funktionsmechanismen, Wirkungen und Gestaltungsoptionen von Regeln in der Institutionenforschung behandelt. In diesem Artikel soll beleuchtet werden, inwieweit sich Ansätze der Institutionenforschung auf Software anwenden lassen und was sich aus dieser Forschungsperspektive zu den Regelungswirkungen und Gestaltungsoptionen von Software ableiten lässt.

Stand, Perspektiven und Folgen des E-Commerce

Ulrich Riehm; Carsten Orwat; Thomas Petermann

Im Auftrag des Ausschusses fur Bildung Forschung und Technikfolgenabschatzung des Deutschen Bundestages fuhrte das Buro fur Technikfolgen-Abschatzung beim Deutschen Bundestag (TAB) in Kooperation mit dem Institut fur Technikfolgenabschatzung und Systemanalyse (ITAS) in den Jahren 2000 bis 2002 das Projekt „E-Commerce“ durch. Entsprechend dem Konzept der Technikfolgenabschatzung wurden die okonomischen sozialen und okologischen Folgen des elektronischen Handels in einzelnen Wirtschaftsbereichen untersucht und politische Handlungsoptionen ausgearbeitet. In diesem Beitrag wird zunachst der gegenwartige Stand des E-Commerce im Allgemeinen dargestellt und anschliesend werden ausgewahlte Branchen betrachtet. Anhand der Lebensmittelbranche wird mit einer Beispielrechnung auf die Verkehrsfolgen des E-Commerce hingedeutet. Mit dem elektronischen Versandhandel von Arzneimitteln verbinden sich einerseits Hoffnungen auf Kosteneinsparungen im Gesundheitswesen andererseits muss mit eine Verringerung der Zahl der Apotheken gerechnet werden was eine andere Modellrechnung zeigt. Gegenlaufige positive und negative Beschaftigungseffekte zeigen sich auch beim elektronischen Handel mit digitalisierten Informationsprodukten und Dienstleistungen.
