Summary Objectives: For planning hospital information systems it is important to recognize the interrelation between business processes and the communication needs between supporting application systems. We therefore present an approach to model, visualize and analyze those interdependencies. Methods: The approach is based on the concepts defined in 3LGM2, a meta-model to describe health information systems (HIS). An information process is defined as a sequence of functions using or updating information; a communication path as a sequence of communication links between interfaces belonging to application systems. The search for communication paths belonging to an information process is interpreted as an all-pairs shortest-paths problem. To solve this problem the Floyd-Warshall algorithm is applied. Results: The resulting algorithm has been implemented as function of the 3LGM2 tool, a tool to create 3LGM2 compliant models. With it, it is possible to interactively define information p...

Summary Background: For more than 30 years, there has been close cooperation between Japanese and German scientists with regard to information systems in health care. Collaboration has been formalized by an agreement between the respective scientific associations. Following this agreement, two joint workshops took place to explore the similarities and differences of electronic health record systems (EHRS) against the background of the two national healthcare systems that share many commonalities. Objectives: To establish a framework and requirements for the quality of EHRS that may also serve as a basis for comparing different EHRS. Methods: Donabedian’s three dimensions of quality of medical care were adapted to the outcome, process, and structural quality of EHRS and their management. These quality dimensions were proposed before the first workshop of EHRS experts and enriched during the discussions. Results: The Quality Requirements Framework of EHRS (QRF-EHRS) was defined and co...

Angesichts der zunehmenden Diskussion uber Referenzmodelle fur Informationssysteme aber auch fur Krankenhausinformationssysteme wird in dieser Arbeit untersucht, was Referenzmodelle sind und bei welchen Aufgaben des Managements von Krankenhausinformationssystemen welche Typen von Referenzmodellen hilfreich sind. Hierzu wird eine Typisierung von Referenzmodellen vorgeschlagen. Beispiele einfach strukturierter jedoch fur die Praxis relevanter Referenzmodelle fur das Management von Krankenhausinformationssystemen werden skizziert.

Gesundheitstelematik bzw. E-Health-Anwendungen sind derzeit ein treibender Faktor für Innovation im Gesundheitswesen [Mu08]. Ziel ist es, durch eine umfassende Sicht auf verteilt entstandene Daten und durch Integration innovativer Gesundheitstechnologien in den Alltag, die Prozesse im Gesundheitswesen effizienter zu gestalten sowie die Patienten in ihrer Eigenverantwortung und ihren Rechten zu stärken [Sp07]. Dies erscheint besonders unter Berücksichtigung der aktuellen Diskussion um den demografischen Wandel notwendig, da effiziente Prozesse und die Mitwirkung auch älterer Patienten helfen können, die immer älter werdende Gesellschaft medizinisch zu versorgen [Ko06]. Dafür sind Anwendungen entsprechend altersgerecht zu gestalten [Ma07].

Die Literatur zum Informationsmanagement ist durch eine Vielzahl unterschiedlicher theoretischer Ansatze und praxisorientierter Frameworks gepragt. Zusammenhange zwischen Aspekten des strategischen Informationsmanagements, der IT Governance, des IT Service Managements und dem Informationssystems sind nicht ausreichend formalisiert, um auf deren Grundlage entscheidungsunterstutzende Werkzeuge fur CIOs und Geschaftsleitung zu konstruieren. Insbesondere in Krankenhausern ist der strategische Einsatz von Komponenten des Informationssystems bei geringen IT-Budgets eine herausfordernde Aufgabe. Im Rahmen des Requirements Engineering eines entscheidungsunterstutzenden Werkzeugs fur den CIO soll ein Semantisches Netz des Informationsmanagements im Krankenhaus (SNIK) konstruiert werden. Diese Arbeit skizziert die Methodik zur Konstruktion des SNIK und stellt Ergebnisse der ersten beiden von sechs Schritten auf dem Weg zu SNIK vor. Um sowohl die Werkzeugentwicklung fur den CIO auf Basis von S...

Health information systems (HIS) are one of the most important areas for biomedical and health informatics. In order to professionally deal with HIS well-educated informaticians are needed. Because of these reasons, in 2001 an international course has been established: The Frank - van Swieten Lectures on Strategic Information Management of Health Information Systems. Reporting about the Frank - van Swieten Lectures and about our students' feedback on this course during the last 16 years. Summarizing our lessons learned and making recommendations for such international courses on HIS. The basic concept of the Frank - van Swieten lectures is to teach the theoretical background in local lectures, to organize practical exercises on modelling sub-information systems of the respective local HIS and finally to conduct Joint Three Days as an international meeting were the resulting models are introduced and compared. During the last 16 years, the Universities of Amsterdam, Braunschweig,...

Not only architects but also information managers need models and modeling tools for their subject of work. Especially for supporting strategic information management in hospitals, the meta model 3LGM2 is presented as an ontological basis for modeling the comprehensive information system of a hospital (HIS). In a case study, requirements for modeling HIS have been deduced. Accordingly 3LGM2 has been designed to describe HIS by concepts on three layers. The domain layer consists of enterprise functions and entity types, the logical tool layer focuses on application components and the physical tool layer describes physical data processing components. In contrast to other approaches a lot of inter-layer-relationships exist. 3LGM2 is defined using the Unified Modeling Language (UML). Models of HIS can be created which comprise not only technical and semantic aspects but also computer-based and paper-based information processing. A software tool supporting the creation of 3LGM2 compliant...

This article is part of the Focus Theme of Methods of Information in Medicine on the German Medical Informatics Initiative. "Smart Medical Information Technology for Healthcare (SMITH)" is one of four consortia funded by the German Medical Informatics Initiative (MI-I) to create an alliance of universities, university hospitals, research institutions and IT companies. SMITH's goals are to establish Data Integration Centers (DICs) at each SMITH partner hospital and to implement use cases which demonstrate the usefulness of the approach. To give insight into architectural design issues underlying SMITH data integration and to introduce the use cases to be implemented. SMITH implements a federated approach as well for its governance structure as for its information system architecture. SMITH has designed a generic concept for its data integration centers. They share identical services and functionalities to take best advantage of the interoperability architectures and of ...

The project KoRegIT (funded by TMF e.V.) aimed to develop a generic catalog of requirements for research networks like cohort studies and registers (KoReg). The catalog supports such kind of research networks to build up and to manage their organizational and IT infrastructure. To make transparent the complex relationships between requirements, which are described in use cases from a given text catalog. By analyzing and modeling the requirements a better understanding and optimizations of the catalog are intended. There are two subgoals: a) to investigate one cohort study and two registers and to model the current state of their IT infrastructure; b) to analyze the current state models and to find simplifications within the generic catalog. Processing the generic catalog was performed by means of text extraction, conceptualization and concept mapping. Then methods of enterprise architecture planning (EAP) are used to model the extracted information. To work on objective a) questionn...

The SNIK project converts textbooks about information management in hospitals to a domain ontology that provides a shared vocabulary for institutions to model and integrate processes, data and infrastructure. To accommodate user groups with different requirements and technical backgrounds, and to support incremental and cooperative development, we create a system architecture to publish, visualize, browse and query the ontology, as well as to evaluate and improve the data quality.

A national German funding initiative for Medical Informatics focusing at data integration for medicine gives an opportunity to reopen a window to Germany. In the open window appears a best paper selection of the 2015 annual conference of the German Society of Medical Informatics, Biometry and Epidemiology and papers of the German journal GMS Medical Informatics, Biometry and Epidemiology (MIBE). The publications in focus deal with data integration by transferring clinical routine data into an electronic data capture (EDC) system, using natural language processing to make unstructured date processable, measuring quality of record linkage, and by using a unified metadata scheme for integrated documentation in laboratories. Two additional papers present methods for data analysis especially for change point detection in binary sequences and for analyzing categorial data.

In medical education and practice, smartphone apps are increasingly becoming popular. In general practice, apps could play an important future role in supporting medical education and practice. To explore medical students' perceptions regarding the potential of a general practice app for training and subsequent work as a physician. Cross-sectional survey among Leipzig fourth-year medical students who were provided with an app prototype for a mandatory general practice course. Response rate was 99.3% (n = 305/307); 59.0% were female and mean age was 24.5 years. Students certified that the app had a higher potential than textbooks in both education (57.4% vs. 18.0%) and practice (47.1% vs. 22.8%). Students' most desired possible app extensions when anticipating its use for subsequent work as a physician were looking up information for diagnostics, therapy and prediction (85.1%), access to electronic patient files (48.1%), communication and networking (44.3%), organization of m...

Health information systems in general and hospital information systems in particular are sometimes compared to large tankers crossing the oceans. Like tankers, these information systems need careful and long-term planning (planning its course), they need continual monitoring to ensure their course is still followed (staying on course), and they react only very slowly to directing (steering) activities.

Computer-based clinical decision support systems (CDSSs) are still today not in widespread use, although there has been extensive research and development for several decades. We have, based on the literature of the last years, summarised some of the problems that may lead to low user acceptance and that should be addressed more extensive in future developments of CDSSs. We describe different aspects of the usefulness of CDSSs according to the elements (relevance, validity, and work) of a formula of usefulness of information, and, in a short section, refer to the discussion about clinical guidelines.
