Introduction To evaluate the impact of non-technical skills (NTS) on team performance, workload and clinical outcomes.

Methods The operating room (OR) environment of 20 robot-assisted radical prostatectomies performed by three different surgeons was recorded. Trained observers assessed NTS utilising the Non-Technical Skills for Surgeons (NOTSS) questionnaire. Associations between NOTSS scores, teamwork attributes (anticipation and inconveniences), workload (measured by National Aeronautics and Space Administration-Task Load Index (NASA-TLX)) and clinical outcomes (operative time, blood loss and surgical complexity) were determined using logistic regression and Pearson correlation.

Results 1780 requests were observed, 703 (39%) were non-verbal. Utilisation of non-verbal requests differed significantly among surgeons (26%, 36% and 44%, p<0.001). Anticipation was significantly associated with ‘Situational Awareness’ (OR 2.59, 95% CI 1.52 to 4.38, p<0.001), ‘Decision Making’ (OR 0.42, 95% CI 0.33 to 0.55, p<0.001) and ‘Communication and Teamwork’ (OR 0.43, 95% CI 0.25 to 0.74, p=0.002) domains. Inconveniences were significantly associated with ‘Situational Awareness’ (OR 0.21, 95% CI 0.08 to 0.59, p=0.003), ‘Decision Making’ (OR 2.73, 95% CI 1.53 to 4.86, p<0.001), and ‘Leadership’ (OR 0.62, 95% CI 0.41 to 0.94, p=0.03). There was a significant positive correlation between NOTSS scores and perceived physical and mental workload measures of NASA-TLX, as well as self-perceived performance. There was no significant association between NOTSS scores and any of the investigated clinical outcomes.

Conclusion NTS in the OR were associated with team efficiency, fewer surgical flow disruptions and an improved self-perceived performance.
