The NATO Centre of Excellence for Military Medicine in Budapest, Hungary, introduced high-fidelity patient simulation into its training courses in 2011. In October, under the direction of MILMED COE Training Branch Chief Dr. Colonel Laszlo Fazekas, the center hosted a “train the trainer” course for military personnel who manage advanced first aid for battle casualties. Twelve experienced NATO medical instructors from Germany, Holland, Hungary and Romania participated in both classroom and field training. Using the CAE Caesar trauma patient simulator, they reviewed practical usage of tourniquets, bandaging and chest needle decompression.
