Medical informatics education needs information system practicums in health care settings–experiences and lessons learned from 32 practicums at four universities in two countries
Management of health information systems

Abstract (Expand)

OBJECTIVES: To report about the themes and about experiences with practicums in the management of information systems in health care settings (health information management) for medical informatics … students. METHODS: We first summarize the topics of the health information management practicums/projects that the authors organized between 1990 and 2003 for the medical informatics programs at Heidelberg/Heilbronn, Germany, UMIT, Austria, as well as for the informatics program at the University of Leipzig, Germany. Experiences and lessons learned, obtained from the faculty that organized the practicums in the past 14 years, are reported. RESULTS: Thirty (of 32) health information management practicums focused on the analysis of health information systems. These took place inside university medical centers. Although the practicums were time-intensive and required intensively tutoring students with regard to health information management and project management, feedback from the students and graduates was mainly positive. DISCUSSION: It is clearly recommended that students specializing in medical informatics need to be confronted with real-world problems of health information systems during their studies.

Modeling Interdependencies between Information Processes and Communication Paths in Hospitals
Management of health information systems

Abstract (Expand)

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 3LGM(2), 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 3LGM(2) tool, a tool to create 3LGM(2) compliant models. With it, it is possible to interactively define information processes at the domain layer and to analyze step by step whether the infrastructure at the logical tool layer is sufficient to communicate necessary data between application systems. Conclusions: The presented approach enables the representation and analysis of dependencies between information processes and communication paths. With it, the HIS architecture is directly associated with the business needs. This is an important condition for the systematic planning of hospital information systems.

Assessing the integration of information system components
Management of health information systems

Abstract (Expand)

This paper presents formal approaches for assessing the integration of information system components. They were developed to support decisions in the strategic management of information systems. The … fulfillment of integration requirements, the dependency of information system components on each other, and the heterogeneity of the integration infrastructure are the major assessment criteria.The meta-model 3LGM2A is the (semi-)formal base for methods introduced here. The fulfillment of integration requirements is checked by matching sets of application components that have specific requirements (requirements domains) with sets of application components that exchange data or call operations related to the requirements (communication domains). Requirements categories support the handling of the numerous specific requirements.For assessing the complexity of an information system or its subsystems the figures degree of informational dependence, degree of functional dependence, and degree of heterogeneity are defined.
