Abstract : Surgical suite management plays a key role in the endeavor of hospitals: patients’ health at sustainable cost. Computerization and automation of processes are conventional solutions to support resource management and efficiency. However, unsuitable support might not improve the management activity, and can even be detrimental to it. Our hypothesis is that usable and flexible interactivity tuned to local particularities can create a working environment in which the medical staff can cope with unexpected surgery events and appropriate the technology. Our contributions comprise an analysis of the activity of the surgical team, based on interviews, observations, review of the literature and an analogy with civil aviation. We participated in the construction of a mathematical model of the surgical workflow and a visualization of the mathematical model. We conducted an experimentation to identify bottlenecks of workflow inefficiencies and delays. We identified scenarios, requirements and design principles necessary to the development, integration and acceptation of a tool to support surgical workflow activities. We designed multi-users interactions on a large surface and made a prototype of electronic whiteboard, OnBoard, for the surgical suite which demonstrates the integration of the specifications and technical challenges. OnBoard belongs to a larger cyber physical system including activity sensors in every operating room of the surgical suite. Finally, we deployed the prototype in a surgical suite and evaluated it. The OnBoard experience suggests that the design of interactions is paramount to provide the medical staff an efficient collaborative environment.
