Intraoperative workload during robotic radical prostatectomy: Comparison between multi da Vinci Xi and da Vinci SP robots

The goal of this study was to quantify and compare prospective self-reported intraoperative workload and teamwork during robot-assisted radical prostatectomy (RARP) for multi-port da Vinci Xi (MP) and single-port da Vinci SP (SP) robots. The self-reported workload (surgeon and surgical team) and teamwork (surgeon) measures were collected and compared between MP and SP RARPs, as well as the learning curve. Results from 25 MP and SP RARPs showed that overall, the NASA-TLX workload subscales were lower, and the teamwork modified NOTECHS subscales were higher for the MP RARPs compared to the SP RARPs. The underlying reason for the significant differences between these two RARP surgical procedures could be other factors (e.g., robot design factors) in addition to the surgeon and surgical team's experience. The results also suggested learning effects through the 25 SP RARPs; however, twenty-five procedures may not be enough to achieve proficiency with the SP system.
