Clinical simulation as a training and knowledge technique allows people to experience a likely scenario with the aim of acquiring knowledge, abilities, and increased aptitude. The filming of the staging represents a useful tool to review the decisions and actions taken, with the purpose of highlighting the strengths, weaknesses, and areas for improvement. To evaluate performance, nursing students are placed in clinical simulations and filmed while facing life-like situations. Some students have claimed that the camera might have caused them to commit more errors thereby hindering their overall performance. To test this, a study was designed in which half of the group would be evaluated using the method of filming while the rest would be evaluated without a camera present. This article details the study above carried out with second year nursing students and tries to evaluate the impact of filming on overall performance during clinical simulations.
