“…In [67,71], the design and implementation of a surgical workflow management system based on SPMs that can provide a robust guidance for surgical activities was described. The number of required iSPMs was investigated by a randomized selection of iSPMs to create a gSPM and subsequent testing of a disjunct iSPM against the gSPM.…”

Due to the rapidly evolving medical, technological, and technical possibilities, surgical procedures are becoming more and more complex. On the one hand, this offers an increasing number of advantages for patients, such as enhanced patient safety, minimal invasive interventions, and less medical malpractices. On the other hand, it also heightens pressure on surgeons and other clinical staff and has brought about a new policy in hospitals, which must rely on a great number of economic, social, psychological, qualitative, practical, and technological resources. As a result, medical disciplines, such as surgery, are slowly merging with technical disciplines. However, this synergy is not yet fully matured. The current information and communication technology in hospitals cannot manage the clinical and operational sequence adequately. The consequences are breaches in the surgical workflow, extensions in procedure times, and media disruptions. Furthermore, the data accrued in operating rooms (ORs) by surgeons and systems are not sufficiently implemented. A flood of information, "big data", is available from information systems. That might be deployed in the context of Medicine 4.0 to facilitate the surgical treatment. However, it is unused due to infrastructure breaches or communication errors. Surgical process models (SPMs) alleviate these problems. They can be defined as simplified, formal, or semiformal representations of a network of surgery-related activities, reflecting a predefined subset of interest. They can employ different means of generation, languages, and data acquisition strategies. They can represent surgical interventions with high resolution, offering qualifiable and quantifiable information on the course of the intervention on the level of single, minute, surgical work-steps. The basic idea is to gather information concerning the surgical intervention and its activities, such as performance time, surgical instrument used, trajectories, movements, or intervention phases. These data can be gathered by means of workflow recordings.These recordings are abstracted to represent an individual surgical process as a model and are an essential requirement to enable Medicine 4.0 in the OR. Further abstraction can be generated by merging individual process models to form generic SPMs to increase the validity for a larger number of patients. Furthermore, these models can be applied in a wide variety of use-cases. In this regard, the term "modeling" can be used to support either one or more of the following tasks: "to describe", "to understand", "to explain", to optimize", "to learn", "to teach", or "to automate". Possible use-cases are requirements analyses, evaluating surgical assist systems, generating surgeon-specific training-recommendation, creating workflow management systems for ORs, and comparing different surgical strategies. The presented chapter will give an introduction into this challenging topic, presenting different methods to generate SPMs from the workflow in the OR, as well as various...

“…A comprehensive representation of the operating context is an important prerequisite for situationaware adaptation of medical devices [5], [6]. Intelligent system's behavior does not solely depend on low-level tasks, but requires a more general kind of understanding of the surgical situation.…”

A workflow-driven cooperative operating room needs to be established in order to successfully unburden the surgeon and the operating room staff very time-consuming information-seeking and configuration tasks. We propose an approach towards the integration of intraoperative surgical workflow management and integration technologies. The concept of rule-based behavior is adapted to situation-aware medical devices. A prototype was implemented and experiments with sixty recorded brain tumor removal procedures were conducted to test the proposed approach. An analysis of the recordings indicated numerous applications, such as automatic display configuration, room light adaptation and pre-configuration of medical devices and systems.
