ABSTRACT
INTRODUCTION AND OBJECTIVE: Surgical missions are still largely on pause due to COVID-19, leading to missed opportunities for skill sharing between high-income and middle to low-income countries. New commercially available augmented reality (AR) technology facilitates surgical training, allowing mentors in one country to virtually train and skill-share with a mentee in another country during surgical cases in real-time. We hypothesize that AR technology is an effective live surgical training and mentorship modality. METHODS: To evaluate perceived effectiveness of AR technology in global urologic surgery training, surgeon mentors in the USA and UK worked with mentees in Benin performing surgical cases using the Proximie AR system. Proximie includes audiovisual capabilities allowing a mentor in any location to provide a mentee with real-time guidance during the procedure. Following each case, mentor and mentee individually completed a questionnaire assessing the technology. RESULTS: Trainers reported AR technology as easy to set-up and use in 73.3% of cases while the trainee reported easy set-up and use in 100% of cases. The visual quality was acceptable to trainers in 60% of cases and “looks like I'm there” in 40%. Visual input/ability to draw on screen had high impact in 80% of cases, with trainers rating the ability to provide anatomical guidance as invaluable or significant in 93.4% of cases. Audio and anatomical guidance had a significant impact for the trainee in 100% of cases. The quality of virtual training v. in-person training was equivalent in 100% of cases for the trainee while trainers found virtual training inferior in 66.7% of cases and equivalent in only 6.7% of cases. Difficulty connecting occurred often in only 1% of cases for trainers but in 12.5% of cases for the trainee. Trainers reported delay or time lag while using the technology in 40% of cases, with lag being problematic in 12.5% of cases. In contrast, the trainee reported rarely experiencing delay or time lag while using the technology in 100% of cases. CONCLUSIONS: AR technology is useful in facilitating realtime surgical mentorship during the COVID-19 pandemic. The Proximie technology provides visualization that is acceptable and audiovisual capabilities that have significant positive impact on successful case completion. Though AR technology presents its own set of challenges such as difficulty in connecting virtually between trainer and trainee as well as delay or time lag during surgical cases, AR technology may prove a welcome alternative when in-person training is unavailable or limited.
ABSTRACT
INTRODUCTION AND OBJECTIVE: Surgical medical missions allow for the global transfer of surgical skills, knowledge, and resources between high and low to middle-income countries to the benefit of both the health professionals involved and their patients. The ongoing COVID-19 pandemic, travel restrictions, and general hesitancy to travel has drastically reduced these missions, thus putting a pause on the exchange of surgical skills and training between countries. Augmented reality (AR) technology can mitigate some of these obstacles. AR technology allows mentors and mentees to work together virtually during a live surgical case. Introduction of AR into surgical mission partnerships allows for the continuation of teamwork mentorship, and learning between international teams. We hypothesize that global urologic surgical training can be successfully undertaken through augmented reality. METHODS: In order to evaluate this, members of our team performed several surgical cases while using the Proximie virtual reality system. The Proximie system includes a console with a camera, display monitor, and supported computer system that allows the mentor to visualize the procedure that is being undertaken in the mentee's home country and provide guidance, both visually and through auditory means, during the operation. RESULTS: Multiple procedures were accomplished with this technology. In this video, we will demonstrate endoscopic as well as open cases with a mentee in Benin and mentors in the United Kingdom and the United States. Mentors were able to guide mentees through entire procedures using the AR technology. The audio capabilities of Proximie permitted real time conversation for direct verbal feedback. Proximie technology's visual component allowed mentors to see multiple views simultaneously including the procedure itself as well as endoscopic, fluoroscopic, and sonographic images. Visual feedback was possible through touch screen capability enabling the mentor to mark and circle specific anatomical locations. CONCLUSIONS: Augmented reality technology is feasible for long distance mentor-mentee interactions and global urology “hands on” surgical training.
