Abstract

Background: Training surgeons is costly and resource intensive, often requiring extended periods of expert supervision. Virtual reality (VR) has shown potential in enhancing surgical skill acquisition, but its use in low- and middle-income countries (LMICs) remains limited. This study aimed to evaluate the feasibility of using smartphone VR for surgical training in LMICs.

Methods: We conducted a prospective randomised controlled feasibility study involving surgical trainees recruited from a government teaching hospital in Freetown, Sierra Leone. Participants were randomised 1:1 VR vs non-VR and received a 2-day hands-on course on lower limb amputation. The VR group received additional VR training consisting of two 30-minute modules with narrated live surgery videos. Feasibility outcomes included recruitment rates, VR intervention adherence, fidelity and acceptability.

Results: A total of 30 participants were randomised, 15 to the VR group and 15 to the control group. The recruitment period lasted 2 days, and 29 participants (96.7%) completed the course. The VR intervention had high fidelity and acceptability, with 100% of participants completing the intervention. There was no unblinding. Compared to the control group, the VR group reported statistically significantly higher engagement during the hands-on course.

Conclusion: Our findings suggest that smartphone VR is technically feasible for surgical training in LMICs, and may improve engagement and perceived learning. With minor modifications to the intervention and assessments, a larger-scale trial is feasible. These results highlight the potential for VR to address the challenges of surgical training in LMICs, where access to expert supervision and costly training resources may be limited.
