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(More)
INTRODUCTION This article is part of the Focus Theme of Methods of Information in Medicine on "Using Data from Ambient Assisted Living and Smart Homes in Electronic Health Records". BACKGROUND Concepts of Ambient Assisted Living (AAL) support a long-term health monitoring and further medical and other services for multi-morbid patients with chronic(More)
Information management in hospitals is a complex task. In order to reduce complexity, we distinguish strategic, tactical, and operational information management. This is essential, because each of these information management levels views hospital information systems from different perspectives, and therefore uses other methods and tools. Since all these(More)
OBJECTIVES 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). METHODS In a case study,(More)
More than 10 years ago Haux et al. tried to answer the question how health care provision will look like in the year 2013. A follow-up workshop was held in Braunschweig, Germany, for 2 days in May, 2013, with 20 invited international experts in biomedical and health informatics. Among other things it had the objectives to discuss the suggested goals and(More)
OBJECTIVES We introduce the 3LGM(2) tool, a tool for modeling information systems, and describe the process of modeling parts of the hospital information system of the Leipzig University Hospital (UKL(a)). We modeled the sub information systems of five patient record archiving sections to support the creation of a proposal for governmental financial support(More)
Information processing in hospitals, especially in university hospitals, is currently faced with two major issues: low-cost hardware and progress in networking technology leads to a further decentralization of computing capacity, due to the increasing need for information processing in hospitals and due to economic restrictions, it is necessary to use(More)
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(More)
OBJECTIVE Both regional health information systems (rHIS) and hospital information systems (HIS) need systematic information management. Due to their complexity information management needs a thorough description or model of the managed information system. METHODS The three layer graph-based meta-model (3LGM(2)) and the 3LGM(2) tool provide means for(More)
The large number of inpatients and outpatients in university hospitals leads to high costs of medical documentation and to an increasing number of medical documents. Due to legal regulations, these medical records have to be stored for 30 years. This implies spatial, organizational, and economical problems. At present, conventional archiving in hospitals(More)
