Objective:
Medical education has been severely disrupted by the COVID-19 pandemic, with many in-person educational activities transitioned to distance learning. To overcome this challenge, we utilized telesimulation to conduct an endoscopic sinus surgery (ESS) dissection course. Our objectives were to evaluate the effectiveness and acceptability of telesimulation as an alternative to in-person dissection courses for resident training.
Study Design:
Cross-sectional study.
Setting:
Academic medical centers.
Methods:
The course, consisting of lectures and hands-on dissection, was conducted entirely over the Zoom platform. The participants were allocated outpatient clinic rooms at 2 hospitals, while the instructors supervised remotely. We utilized the camera systems in the clinics and 3-dimensional-printed sinus models for the dissection. Laptops with cameras were used to capture the endoscopic image and the dissector. We evaluated the effectiveness of telesimulation, the surgical skills of the participants, and the course by way of pre- and posttest and a questionnaire.
Results:
A total of 8 participants and 7 instructors participated in the study. Telesimulation was found to be effective in helping participants gain knowledge and skills in ESS. All participants improved on their pretest scores (31.5% vs 73.4%, P = .003) and felt more comfortable with ESS postcourse (1.9 vs 3.2, P = .008). Participants and instructors opined that telesimulation is an acceptable alternative to in-person dissection courses.
Conclusion:
Telesimulation is an effective, acceptable, and viable alternative to in-person dissection courses. It also has the advantage of overcoming temporal and geographic constraints to surgical training in residency.
