Video recordings 14 simulated video recordings will be made showing general surgeons "acting" in their own roles during surgery. The scenarios will be scripted to display various scenarios of routine (such as unnoticed prolongation of a laparoscopic appendectomy) and non-routine situations (such as unexpected bleeding during open surgery). The scenarios will be designed after a specific structure aiming at a specific variation in the surgeons' non-technical performance according to the four categories of NOTSSdk.
