Does the NASA-TLX score correlate with surgical difficulty and operative metrics?
The NASA-TLX score is a valid tool to assess surgical difficulty and could be used to monitor trainee proficiency.
The NASA TLX score provides a graded numerical score that that correlated significantly with the surgeon's assessment of the technical difficulty, and with operative duration, intra-operative blood loss and previous abdominal surgery. This novel application of this tool could be employed in both research and teaching settings to score surgical difficulty and monitor a trainee's proficiency over time.
