    Fraud-Detection im Gesundheitswesen: Data-Mining zur Aufdeckung von Abrechnungsbetrug
    (HMD Praxis der Wirtschaftsinformatik: Vol. 54, No. 1, 2017) Könsgen, Raoul; Stock, Steffen; Schaarschmidt, Mario
    Im Gesundheitswesen belaufen sich die Betrugskosten auf circa 5,6 Prozent, die Tendenz ist weiter steigend (Neuber 2011). Für Deutschland würde dies im Jahr 2014 etwa 18,3 Mrd. Euro an Betrugskosten bedeuten (Statistisches Bundesamt 2016). Steigende Krankenversicherungsbeiträge und eine neue Auffassung von gesetzlicher medizinischer Grundversorgung sind die Folgen. Es handelt sich bei Abrechnungsbetrug um eine besonders sozialschädliche Form der Wirtschaftskriminalität, da die Integrität des Gesundheitswesens insgesamt negativ beeinflusst wird (Bundeskriminalamt 2004). Zudem stehen Krankenversicherungen in einer dynamischen Umwelt und bei stetig steigendem Konkurrenzdruck vor der Herausforderung ihre Kosten zu senken. Die Abrechnungsdatensätze der Ärzte unterliegen regelmäßiger Änderungen und werden zunehmend komplexer. Dies führt dazu, dass es für die Rechenzentren der Krankenversicherungen zunehmend schwieriger sein wird, Informationen zur Aufdeckung von Abrechnungsbetrug zu extrahieren. Data-Mining zählt zu den Analysemethoden von Business Analytics und wird zur Mustererkennung in großen Datenbeständen verwendet. Die vorliegende Arbeit liefert einen Erkenntnisbeitrag zu Umsetzungsmöglichkeiten eines Fraud-Detection-Systems, auf Basis einer Data-Mining-Assoziationsanalyse.AbstractThe health care fraud costs in Germany totaled 21 bn euro in 2014 (Statistisches Bundesamt 2016) and the numbers continue to grow. Rising health care contributions and a new view with regard to basic medical care are the consequences. From the the German Federal Criminal Office point of view, accounting fraud is a socially harmful conduct. At the same time, health insurances face the challenge to reduce their costs. The accounting data from medical doctors are subjected to continuous change and become increasingly complex. Due to this, it becomes more difficult to extract useful information out of this enormous volume of data. Data-mining is part of the analysis methods of business analytics and is used to pattern recognition. The intention of this paper a new contribution to implementation possibilities of a fraud-detection-system that is based on data-mining-association-analysis.

    Living Labs als Forschungsinstrument für Ambient Assisted Living Technologien
    (i-com: Vol. 11, No. 3, 2012) Rashid, Asarnusch; Reichelt, Christian; Röll, Natalie; Zentek, Tom
    Seit über vier Jahren setzt das FZI Forschungszentrum Informatik die Living Lab Methode zur Forschung an Ambient Assisted Living (AAL) Technologien ein. Ca. 15 wissenschaftliche Mitarbeiter aus unterschiedlichen Projekten und Disziplinen arbeiten hier zusammen, um innovative Assistenzsysteme für ältere bzw. körperlich und kognitiv eingeschränkte Menschen zu entwickeln. Das Living Lab erwies als sehr hilfreich, um zum einen techni-sche Möglichkeiten aufzuzeigen und zum anderen Benut-zerakzeptanzanalysen und Usability Tests von AAL Tech-nologien durchzuführen. Dieser Beitrag beschreibt den theoretischen Rahmen der Living Lab Methodik und die Erfahrungen mit der Umsetzung des Living Lab zur For-schung an AAL Technologien.

    Lösungsarchitektur für die Einführung der elektronischen Gesundheitskarte und der auf ihr basierenden Anwendungen
    (Wirtschaftsinformatik: Vol. 47, No. 3, 2005) Frießem, Paul; Kalmring, Dirk; Reichelt, Peter
    In Germany it is intended that each insurant in the compulsory health insurance will get a Patient Data Card by 2006-01-01. This project report characterizes the present state of the system architecture for the telematics infrastructure elaborated by the self-administration of German health care. The introduction of the Patient Data Card aims at increasing the quality in medical care as well as improvement of cost effectiveness and transparency of health care output. The great deal of actors and the high amount of requirements concerning law including data privacy, and engineering including security and reliability cause a highly complex project. The overall system architecture is based on legacy systems which are connected to the telematics infrastructure and its new services by special modules.

    Virtual Reality in Health Care Education: A Study about the Effects of Presence on Acceptance and Knowledge Improvement among Health Care Students
    (DELFI 2020 – Die 18. Fachtagung Bildungstechnologien der Gesellschaft für Informatik e.V., 2020) Plotzky, Christian; Lindwedel-Reime, Ulrike; Bejan, Alexander; König, Peter; Kunze, Christophe
    With an ever-increasing need of skilled healthcare workers, efficient learning methods like Virtual Reality are becoming increasingly important. A VR simulation for endotracheal suction intervention was developed and tested. The aim of this pilot study is to examine the VR simulation’s acceptance and knowledge improvement. Furthermore, the effect of presence on acceptance and knowledge improvement was investigated. A total of 51 students participated in the pilot study, using pre-post-test design. A modified Unified Theory of Acceptance and Use of Technology (UTAUT) and Igroup Presence Questionnaire (IPQ) were used. Correlation and regression analysis were performed. Pre- and post-tests showed a significant knowledge improvement (p<0.001). Correlation between presence and behavioural intention was highly positive (r=0.52, p<0.001). Performance and effort expectancy are dominant in effect on behavioural intention of using VR learning simulation. The results indicate that a simulation, which conveys a higher sense of presence, is more likely to be accepted.

    Virtual Reality in Healthcare Skills Training: The Effects of Presence on Acceptance and Increase of Knowledge
    (i-com: Vol. 20, No. 1, 2021) Plotzky, Christian; Lindwedel, Ulrike; Bejan, Alexander; König, Peter; Kunze, Christophe
    With an ever-increasing need of skilled healthcare workers, efficient learning methods like Virtual Reality (VR) are becoming increasingly important. We developed and tested a VR simulation for endotracheal suctioning. The aim of this pilot study was to examine the VR simulation’s acceptance and increase of knowledge among participants. Furthermore, the effects of presence on acceptance and increase of knowledge were investigated. A total of 51 students participated in the pilot study, using a quasi-experimental pre-post-test design. A modified Unified Theory of Acceptance and Use of Technology (UTAUT) and the Igroup Presence Questionnaire (IPQ) were used. Correlation and regression analyses were performed. Pre- and post-tests showed a significant increase of knowledge (p < 0.001). The correlation between presence and behavioural intention was highly positive (r = 0.52, p < 0.001). Performance and effort expectancy are dominant effects on behavioural intention of using the VR simulation as an educational tool. The results indicate that a simulation which conveys a higher sense of presence is more likely to be accepted by learners. Regarding outcomes of presence on increase of knowledge, we found no significant correlation. Based on our study, we propose a design for a future mixed reality simulation with haptic elements and a plan on how to assess skills improvement.
