Model-guided Therapy and Surgical Workflow Systems are two interrelated research fields, which have been developed separately in the last years. To make full use of both technologies, it is necessary to integrate them and connect them to Hospital Information Systems. We propose a framework for integration of Model-guided Therapy in Hospital Information Systems based on the Electronic Medical Record, and a taskbased Workflow Management System, which is suitable for clinical end users. Two prototypes - one based on Business Process Modeling Language, one based on the serum-board - are presented. From the experience with these prototypes, we developed a novel personalized visualization system for Surgical Workflows and Model-guided Therapy. Key challenges for further development are automated situation detection and a common communication infrastructure.
Informationstechnische Systeme, die den Arbeitsablauf im klinischen Bereich unterstützen, sind aktuell auf organisatorische Abläufe beschränkt. Diese Arbeit stellt einen ersten Ansatz vor, wie solch ein System in den perioperativen Bereich eingebracht werden kann. Hierzu wurde eine Workflow Engine mit einer perioperativen Prozess-Visualisierung verknüpft. Das System wurde nach Modell-View-Controller-Prinzip implementiert. Als „Controller“ kommt die Workflow Engine zum Einsatz; also „Modell“ ein Prozessmodell, mit den erforderlichen klinischen Daten. Der „View“ wurde durch eine abgekoppelte Anwendung realisiert, welche auf Web-Technologien basiert. Drei Visualisierungen, die Workflow Engine sowie die Anbindung beider über eine Datenbankschnittstelle, wurden erfolgreich umgesetzt. Bei den drei Visualisierungen wurden jeweils eine Ansicht für den OP-Koordinator, den Springer und eine Ansicht für die Übersicht einer OP erstellt.
Information systems, which support the workflow in the clinical area, are currently limited to organizational processes. This work shows a first approach of an information system supporting all actors in the perioperative area. The first prototype and proof of concept was a task manager, giving all actors information about their task and the task of all other actors during an intervention. Based on this initial task manager, we implemented an information system based on a workflow engine controlling all processes and all information necessary for the intervention. A second part was the development of a perioperative process visualization which was developed based on a user centered approach jointly with clinicians and OR members.
An operating room is a stressful work environment. Nevertheless, all involved persons have to work safely as there is no space for mistakes. To ensure a high level of concentration and seamless interaction, all involved persons have to know their own tasks and the tasks of their colleagues. The entire team must work synchronously at all times. To optimize the overall workflow, a task manager supporting the team was developed. In parallel, a common conceptual design of a business process visualization was developed, which makes all relevant information accessible in real-time during a surgery. In this context an overview of all processes in the operating room was created and different concepts for the graphical representation of these user-dependent processes were developed. This paper describes the concept of the task manager as well as the general concept in the field of surgery.
