Simulation of medical emergencies with subsequent video-debriefing allows for the training of complex medical scenarios. Several video-feedback-systems are commercially available, but the acquisition can be expensive and could therefore restrict the spreading of medical simulation. To enable potentially patient-saving simulation training also for financially weaker institutions, we tried to establish a high-fidelity video-feedback-system based on open-source software and inexpensive hardware.

After assessing the requirements at an interdisciplinary conference, a student team realized the video-feedback-system.

A combination of audio technology and high-definition network cameras is used for digital recording. The open-source software “VLC media player” merges the video signal, audio signal and the vital sign monitor and generates a video stream. This stream is wirelessly broadcasted and thus playable by almost every device. Bi-directional communication between supervisor und trainees is possible through headsets. The cameras and the recording can be operated using an in-house programmed software. Following the simulation scenario, the recordings are available for debriefing as well as optionally via the internet.

Currently, the newly-established video-feedback-system is under intensive testing and further development. In particular, maintenance effort and reliability have to be evaluated. This fully equipped system costs roughly 9,000€, but the flexible solution will enable significantly more reasonable systems as well.

The open-source based approach represents a low-cost and scalable alternative to commercially available solutions.

A high-quality video-feedback-system can be established with inexpensive hardware and open-source software. Long-term experience has to show reliability and practicability.
