Why the study?
The study aimed to determine whether personal resourcefulness can be assessed by monitoring stress and visual attention parameters, and whether these relate to psychomotor skills in surgical education.
Does the presence of stressors affect physiological stress markers and psychomotor skills in surgeons performing a laparoscopic task?
Observational (n=8)
Does the presence of stressors affect physiological stress markers and psychomotor skills in surgeons performing a laparoscopic task?
Physiological stress markers like galvanic skin response correlate with psychomotor performance metrics in surgeons, suggesting personal resourcefulness can be objectively monitored during surgical training.

Stressors may impair laparoscopic performance via physiological changes; leaves open validation of GSR monitoring for resourcefulness training.
Modern surgical education is focused on making use of the available technologies in order to train and assess surgical skill acquisition. Innovative technologies for the automatic, objective assessment of nontechnical skills are currently under research. The main aim of this study is to determine whether personal resourcefulness can be assessed by monitoring parameters that are related to stress and visual attention and whether there is a relation between these and psychomotor skills in surgical education. For this purpose, we implemented an application in order to monitor the electrocardiogram (ECG), galvanic skin response (GSR), gaze and performance of surgeons-in-training while performing a laparoscopic box-trainer task so as to obtain technical and personal resourcefulness' metrics. Eight surgeons (6 nonexperts and 2 experts) completed the experiment. A total of 22 metrics were calculated (7 technical and 15 related to personal resourcefulness) per subject. The average values of these metrics in the presence of stressors were compared with those in their absence and depending on the participants' expertise. The results show that both the mean normalized GSR signal and average surgical instrument's acceleration change significantly when stressors are present. Additionally, the GSR and acceleration were found to be correlated, which indicates that there is a relation between psychomotor skills and personal resourcefulness.
