Ergonomic assessment of robotic general surgeons: a pilot study.

Inadequacies exist in the ergonomics of upper body positioning of robotic surgeons; these deficits in biomechanical efficacy predispose surgeons to musculoskeletal injury. Ergonomics and biomechanics may be objectively measured using the Rapid Entire Body Assessment (REBA) and the Rapid Upper Limb Assessment (RULA) to quantify ergonomic efficacy. The purpose of this study is to use validated ergonomic tools to assess the posture of robotic surgeons to examine deficiencies. Four robotic surgeons using the da Vinci model were observed for a minimum of 30 min each. An Xbox connect camera was positioned 10 feet away from the surgeon console. Kinetisense software measured position of the head, shoulders, mid-spine, hips, and knees. One image was captured every 30 s. The software measured the positions in centimeters that deviated from an ideal central postural line (plumb line). RULA and REBA were also employed to assess posture using a still image at 15 min. The average RULA score for the four surgeons was 4.75 (range 3-6). The average REBA score for the four surgeons was 7 (range 5-8). The average RULA score of 4.5/7 and the average REBA of 7/15 qualify as medium risk with the recommendation that action is needed to improve ergonomics. While this pilot study is limited in size, it demonstrates the need for further investigation. With more than half of surgeons reporting musculoskeletal pain after robotic surgery (McDonald et al. in Gynecol Oncol 134:243-247, 2014), poor posture may offer an explanation.

A Standardized Robotic Training Curriculum in a General Surgery Program.

BACKGROUND AND OBJECTIVES: The general surgery residency at the University of Illinois College of Medicine at Peoria has a long tradition of integrating robotic surgery into training since 2002. The purpose of this paper is to investigate our curriculum and evaluation system, which was designed to achieve a standardized format for education in general robotic surgery. METHODS: The curriculum consists of two phases: phase 1 (PGY 1-2): Complete 4 robotic surgery training modules; read two assigned robotic surgery articles; and practice simulation modules on the robot. phase 2 (PGY 3-5): Refresh training modules, score >90% on the simulator modules every 6 months; bedside assist minimum of 4 robotic procedures; and act as console surgeon for a minimum of 10 procedures with 2 separate attending surgeons. The required simulator modules were specially selected to incorporate all of the skills categories documented in the simulator. The faculty evaluate the resident's operative performance using the Global Evaluative Assessment of Robotic Skills validated rubric. RESULTS: Since the curriculum was instituted in June 2017, 73 evaluations from 8 surgeons have been collected. We examined data from 6 residents who had at least 5 Global Evaluative Assessment of Robotic Skills assessments completed. Correlation coefficient scores showed a positive correlation ranging from 0.476 to 0.862 for average skills and 0.334 to 0.866 for overall performance scores. DISCUSSION: The preliminary results suggest an improvement of resident robotic surgical skills through tailored education. This curriculum is designed to enhance robotic general surgery education that could potentially produce general surgeons able to operate robotically without needing a robotic/MIS (Minimally Invasive Surgery) fellowship.
