Identify barriers to surgical simulation in multiple countries across the income spectrum. Evaluate whether a novel, portable surgical simulator (GlobalSurgBox) would be valuable to surgical trainees and overcome these barriers.

Trainees from high-, middle-, and low-income countries were instructed on how to perform surgical skills using the GlobalSurgBox. Participants were sent an anonymized survey after 1 week to evaluate practicality and helpfulness of the trainer.

Academic medical centers in 3 countries: USA, Kenya, and Rwanda.

48 medical students, 48 surgery residents, 3 medical officers, and 3 cardiothoracic surgery fellows.

99.0% of respondents agreed surgical simulation was an important aspect of surgical education. Despite 60.8% having access to simulation resources, only 3 of 40 (7.5%) US trainees, 2 of 12 (16.7%) of Kenyan trainees, and 1 of 10 (10.0%) Rwandan trainees used these resources routinely. 38 (95.0%) US trainees, 9 (75.0%) Kenyan trainees, and 8 (80.0%) Rwandan trainees with access to simulation resources stated there were barriers to using them. The frequently cited barriers included lack of convenient access and lack of time. After using the GlobalSurgBox, 5 (7.8%) US participants, 0 (0%) Kenyan participants, and 5 (38.5%) Rwandan participants reported lack of convenient access as a continued barrier to simulation. 52 (81.3%) US trainees, 24 (96.0%) Kenyan trainees, and 12 (92.3%) Rwandan trainees stated the GlobalSurgBox was a good facsimile of the operating room. 59 (92.2%) US trainees, 24 (96.0%) Kenyan trainees, and 13 (100%) Rwandan trainees stated the GlobalSurgBox better prepared them for clinical settings.

A majority of trainees across all 3 countries reported multiple barriers to simulation in their current surgical training. The GlobalSurgBox eliminates many of these barriers by providing a portable, affordable, and realistic way to practice skills needed in the operating room.
