Correlation between workload and teamwork among residents in DIEP Flap surgery

The goal of this study was to evaluate residents’ workload and teamwork and the correlation between their workload and teamwork subscales during deep inferior epigastric perforator (DIEP) flap surgery. Ten residents who assisted during DIEP flap procedures completed an electronic survey following each DIEP flap procedure from July 2019 to August 2020. The survey contained items from the NASA-TLX and SURG-TLX and questions to measure teamwork subscales. Across 29 surgical cases, 38 surveys were recorded. Overall, the means of workload subscales were mostly greater than 10 and less than 15 (range=020) and the means of all teamwork subscales were greater than 15 (range=0-20). Good teamwork was correlated with lower distractions (Rs=-0.36 to-0.48) and better performance (Rs=0.35 to 0.52). Also, all the teamwork subscales were highly correlated (Rs= 0.59 to 0.92). Our findings suggest that good teamwork, low distractions, and successful performance are generally observed together; however, a causative relationship could not be established based on these results.
