Abstract

Health services research (HSR) is a scientific field analyzing personal health services regarding quality and efficiency. In particular, it focuses on discovering and analyzing health care processes. Of special interest are the factors of influence like the age of the patients and their impact on the processes. Multidimensional process mining is a way to discover health care processes according to certain factors of influence. Because the existing approach for multidimensional process mining from literature is unsatisfactory (e.g., missing separation of process model and visualization), a novel approach is developed. The basic idea is to move the multidimensional aspects directly into the event log which is a record of all events of the process activities serving as a foundation for process mining. OLAP operations are defined to select traces as input for usual process discovery algorithms. For a representation of results adequate to the user needs, several kinds of visualization are provided. During an optional step of consolidation it is possible to reduce the complexity of the mining results, e.g., by clustering process models. This paper motivates this approach and outlines its basic ideas at the early stage of PhD work.
