Medical errors rank high amongst leading causes of death. Especially in emergency care, when there is limited time to think, the "human factor", the interface between human action and the environmental system, has been recognized to be a critical part that determines the outcome. Recent models of human error are based on the principle that critical incidents are of multifactorial origin and reflect insufficiencies of the underlying system itself. The Human Simulation Center (HSC) was built specifically to train interaction between medical teams and to investigate the human factor in medical emergencies. In the following article we present "MevidIO", a live-monitoring and debriefing application framework. Developed for a full-scale simulation center designed to model error transduction in medical emergency care process chains, the framework integrates educational and scientific aspects.
