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 precondition for systematic information management is a strategic information management plan that has to be monitored constantly. In general, such a plan is a paper document that goes out of date fast, what reduces the acceptance among the users even faster. Moreover, in the majority of cases no systematic monitoring of whether the goals described in(More)
An approach to reduce the complexity of information management is to distinguish it into strategic, tactical and operational management with each of the levels using its own software tools. In practice, the management levels are tightly connected and interact closely. The most evident information that has to be interchanged between the management levels is(More)
The correct manipulation of semantic information is essential for the development and implementation of medical guideline server. This is a knowledge based information system for computer-aided processing of clinical practice guidelines. In this study the following core functions are involved in the data processing of guideline server: (1) information(More)
To avoid the problem of knowledge acquisition bottleneck a process oriented method for knowledge acquisition was developed. The approach is based on so called scenarios. A scenario describes a certain step within the decision process to be elicited from the medical expert. By using scenario techniques the knowledge engineer is able to represent the elicited(More)
