The National Aeronautics and Space Administration‐task load index: <scp>NASA‐TLX</scp>: evaluation of its use in surgery

Abstract

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.
