AB  - AimsTechnical skill is associated with improved postoperative outcomes. Adoption of a formalised high-stakes assessment of surgical skill is technically challenging and limited by the financial and human resources available. We aimed to assess the ability to adopt gaze behaviour analysis as an assessment of surgical skill within live open inguinal herniorrhaphy.MethodsSurgeons’ gaze was measured with Tobii Pro eye-tracking Glasses 2 (Tobii AB). All grades of surgeons were included. Primary outcomes were dwell time (%) and fixation frequency (count/s), as markers of cognition, on areas of interest correlated to mean Objective Skill Assessment of Technical Skill score. Secondary outcomes assessed effort and concentration levels through maximum pupil diameter (mm) and rate of pupil change (mm/s) correlated to perceived workload (SURG-TLX). Three operative segments underwent analysis: mesh preparation, fixation and muscle closure. Spearman’s and Pearson’s correlation were performed with significance set at p < 0.05.Results5 cases were analysed, totalling 270 minutes of video footage. All participants were senior surgical trainees and right-hand-dominant. The median number of hernia operations performed was 160 (range:100-500). The median ASA score of each patient participant was 2 (range:1-2). The median operation length was 45 mins (range:40-90 mins). There were no statistically significant primary outcomes from this pilot data (p > 0.05).ConclusionsThis pilot study demonstrated the feasibility of recording gaze behaviours for comparison against formal skills assessment to determine the role of eye tracking in live high stakes technical skills assessment. A full study will now commence based on formal power calculation.
