We developed and evaluated the utility and feasibility of 2 endoscopic monitor screen overlays designed to standardize directional instruction. METHODS: For a baseline perspective on laparoscopic instruction, we video-recorded and qualitatively analyzed 20 teaching cases. We then designed and printed 2 transparent endoscopic monitor overlays: an alphanumeric grid (AG) and a clock. In a laparoscopic simulation lab, 63 medical students were randomized into 3 groups of 21: control, AG, and clock. AG and clock groups were given overlay-specific instructions. All groups completed 3 trials of 6 transfer tasks. Completion and error rates were recorded. We then trialed the overlays in 44 teaching cases in urology and general surgery (30 AG and 14 clock). All cases were video recorded, transcribed, and qualitatively analyzed. Participants completed follow-up experiential surveys with 6-point Likert scales of agreement and space for comments. RESULTS: In the baseline cases, instructors often used directional terms (e.g., screen left/right; up/down) and pointed to the screen during instruction. In the simulation study, the AG group demonstrated the lowest error rates which became significant by trial 3 (p=0.01). 6 instructors and 21 residents from urology (n=14) and general surgery (n=7) participated in the intraoperative evaluation of the overlays. Instructors rated the AG higher than the clock in improving efficiency and hand-eye coordination (p’s<0.001) and agreed that it should be used in the residency program. Trainees rated the AG higher in improving operative technique and confidence in the OR (p’s<0.001). Instructors were more likely to recommend use of the AG over the clock (p=0.004). CONCLUSIONS: We showed that an AG overlay used with standardized commands significantly improved instruction and learning during simulated and live laparoscopic cases. Further work will involve the evaluation of the economy of motion and errors while using the overlay. This could lead to the use of a heads-up display for laparoscopic and robotic training. Further exploration of instructor-trainee discourse is necessary when considering the development and implementation of new methods to improve intraoperative teaching in the era of competency-based medical education.
