“…Franke and Neumuth developed three message exchange patterns to provide different devices with contextual information [ 23 ]. Multi-perspective information [ 30 ] is collected by a central Workflow Information System (WIS) [ 31 ] using intraoperative sensors. Medical devices receive contextual information from this WIS for the adaptation to the current intraoperative situation.…”

Purpose Context awareness in the operating room (OR) is important to realize targeted assistance to support actors during surgery. A situation recognition system (SRS) is used to interpret intraoperative events and derive an intraoperative situation from these. To achieve a modular system architecture, it is desirable to de-couple the SRS from other system components. This leads to the need of an interface between such an SRS and context-aware systems (CAS). This work aims to provide an open standardized interface to enable loose coupling of the SRS with varying CAS to allow vendor-independent device orchestrations. Methods A requirements analysis investigated limiting factors that currently prevent the integration of CAS in today's ORs. These elicited requirements enabled the selection of a suitable base architecture. We examined how to specify this architecture with the constraints of an interoperability standard. The resulting middleware was integrated into a prototypic SRS and our system for intraoperative support, the OR-Pad, as exemplary CAS for evaluating whether our solution can enable context-aware assistance during simulated orthopedical interventions. Results The emerging Service-oriented Device Connectivity (SDC) standard series was selected to specify and implement a middleware for providing the interpreted contextual information while the SRS and CAS are loosely coupled. The results were verified within a proof of concept study using the OR-Pad demonstration scenario. The fulfillment of the CAS’ requirements to act context-aware, conformity to the SDC standard series, and the effort for integrating the middleware in individual systems were evaluated. The semantically unambiguous encoding of contextual information depends on the further standardization process of the SDC nomenclature. The discussion of the validity of these results proved the applicability and transferability of the middleware. Conclusion The specified and implemented SDC-based middleware shows the feasibility of loose coupling an SRS with unknown CAS to realize context-aware assistance in the OR.

A workflow-driven cooperative working environment needs to be established in order to successfully unburden the surgeon and the OR staff from technical configuration and information-seeking tasks. An important prerequisite for autonomous situationaware adaptation of medical devices is a comprehensive representation of the operating context regarding the surgical process and situation.We propose a hierarchical structuring of process-related and situation-related information entities and include assessment scores that intraoperative workflow information systems may provide via OR networks. The conducted experiments on the proposed assessment scores included sixty recorded brain tumour removal procedures and considered 344 distinguishable surgical situations.A comprehensive modelling of surgical situations and process context will be a significant pre-requisite for reliable autonomous adaptation of medical devices and systems in digital operating rooms.

The paper presents an unusual design paradigm for the development of advanced operating rooms and its implementation. The aim of this approach is moving forward the state of art in operating room design and management. First, the used paradigm to implement the mentioned design methodology is described comparing the operating room context environment with a music perspective. This approach has inspired the development of independent systems which are linked together thanks to a communication common framework called OPERA. Secondly, the OPERA system consisting of heterogeneous set of novel robotic devices and innovative information technology techniques are described. The OPERA hardware and software subsystems modules perform their peculiar activities as a whole like orchestral musicians performing an opera. In particular robotic subsystems (developed by The
