About this study
In May 2023, the French National Authority for Health published a solution for patient safety regarding tunnel vision. This concept, which is uncommon in the medical field, is defined as any situation in which a professional's attention is so focused on a goal that they do not hear or see warning signs that should prompt them to change their approach or even stop before an adverse event associated with care occurs.
To better understand the causes of medical errors, the research will assess surgeons' mental fatigue and the factors associated with it. This fatigue, which occurs after or during prolonged periods of intense cognitive activity, is associated with a temporary inability to maintain optimal cognitive performance. Assessing mental fatigue is crucial in surgeons, as it can directly affect their ability to perform complex procedures and make critical decisions. The aim of this research is to examine the factors that may influence the level of mental fatigue and cognitive load in surgeons during surgical procedures.
