Proposal for Requirements Driven Design Science Research

Design Science Research DSR still reveals several methodical shortcomings, which need to be remedied in order to enhance the maturity of DSR and its derived artifacts. For instance, there is a remarkable lack in methodical support for problem formulation. Also, DSR does not provide detailed procedure models, which can be operationalized appropriately. This compromises rigor within the design process and hampers demarcation from professional practice. In order to tackle these issues, we propose the adaptation of Requirements Engineering for structuring the problem space and deriving design decisions systematically. Requirements are also intended to work as glue between single design stages in order to keep the design process comprehensible and transparent. We therefore justify an ontology-based analogy between requirements analysis and DSR parts and provide a requirements-driven DSR framework based on a four-part ontology that especially focuses problem analysis and design preparation. Moreover, a detailed state of the art is presented and our approach is discussed within a critical appraisal.

Certification of Service-oriented eHealth Platforms

Certification of interoperability is an important quality measure, which can foster the success of eHealth projects. Often these projects test and certify interoperability for specific purposes. The achievement of long-term interoperability is often not in the scope of these projects. In this paper we describe the importance of expandability for the long-term interoperability. Further we show, how a structured criteria catalogue for the certification process can be derived for these two quality factors.

Clinical processes from various angles - amplifying BPMN for integrated hospital management

The design and management of information systems is driven by model-oriented approaches on different levels of abstraction. For instance, enterprise models link the organizational action system and corresponding information systems. Enterprise models are generally perceived as measures to close the gap between business and IT, as it is in the healthcare domain. Clinical Pathways (CPs) represent value-added processes of hospitals and are typically described by respective process modeling languages like BPMN. However, a solitary focus on processes is insufficient for utilizing the potential of the model. Instead, it is rather advisable to consider various perspectives in order to completely represent the organizational action system of a hospital. We therefore propose to extend clinical process models with accordingly required perspectives for the representation of satellite objects, e.g. medical resources. Based on previous work, this paper motivates the approach of (process-based) integrated hospital modeling and presents the architecture and design of a revised BPMN extension for multi-perspective modeling. The applicability of the proposed BPMN extension is demonstrated by modeling a CP part for the treatment of stroke patients, which explicitly integrates the process and resource perspective.

Towards Adaptive Pathways: Reference Architecture for Personalized Dynamic Pathways

The usage of clinical pathways to describe and organize the treatment of patients in inter-sectoral care has been established through the last decade. In particular, engaging the patient in the treatment process has become more important. Adequate tools and concepts are needed to improve the integration of patients into inter-sectorial care processes. Personalized dynamic pathways form patient-specific extensions for clinical pathways as a flexible instrument that goes beyond traditional application of pathways. They support customizing care for patient-specific requirements as well as adding patient interaction to the care process. This paper adapts the concept of personalized dynamic pathways and proposes a reference architecture for integrating personalized dynamic pathways into existing inter-organizational healthcare information systems.

Nachhaltigkeit von E-Health-Projekten

Der Einsatz von Informations- und Kommunikationstechnik im Gesundheitswesen, kurz E-Health, wird schon langer als Moglichkeit gesehen, das Gesundheitswesen effektiver zu gestalten und dadurch Kosten zu sparen sowie die Qualitat der Versorgung zu verbessern. Die Verstetigung innovativer, auf modernen E-Health-Technologien basierender intersektoraler medizinischer Versorgung scheitert in Deutschland heute jedoch haufig an der fehlenden Verwertungsbasis und dem Pilotcharakter durchgefuhrter E-Health-Projekte, die wiederum als Negativbeispiel fur eine breitenwirksame Ubertragung von Losungen herangezogen werden.
