In several fields of the medical domain guidelines are used, opening up scope of actions for the medical practitioner. However, there is a gap between the theoretical knowledge they provide and practical solutions performed by the medical expert. Furthermore, barriers of implementation can arise. We propose a framework for modeling medical guidelines which takes these challenges into account. It is based on activities of the Unified Modeling Language (UML). These UML activities serve as an interface for more complex models, that can be used for advanced assistance functions. In this report we focus on translation rules transferring UML activities into Yet Another Workflow Language (YAWL).
