Objectives
Synthesize evidence on (1) transfer of skills acquired with virtual reality robotic surgery simulators (VR-RSS) to nonvirtual settings, (2) equivalence or noninferiority versus nonvirtual training, and (3) downstream clinical outcomes.
Design
PRISMA-conformant systematic review with a prospectively registered protocol. Risk of bias was appraised with RoB 2 (RCTs) and ROBINS-I (nonrandomized studies); certainty of evidence used GRADE with an imprecision adaptation (decision-threshold confidence intervals and scaled optimal information size).
Setting
Searches of major bibliographic databases and grey sources through September 2025; studies conducted in academic skills labs, simulation centers, or clinical environments, with nonvirtual outcome assessments (bench/animal/cadaveric tasks, simulated or live operations, or patient outcomes).
Participants
Medical students, surgical residents, or practicing surgeons trained on commercially available VR-RSS devices and evaluated on nonvirtual tasks or clinical endpoints.
Results
Twenty-five studies met criteria (13 randomized, 5 nonrandomized comparatives, 7 single-group pre/post). Across designs, VR-RSS training improved proximal nonvirtual performance—faster task completion, fewer errors, and higher GEARS/OSATS/GOALS scores. Two randomized trials found no important difference versus control; these null results were internally coherent and did not contradict the overall direction of benefit. Evidence for translation to live operative performance or patient-level outcomes was limited and heterogeneous. Risk of bias varied—generally lower in recent randomized trials—while imprecision was pervasive due to small samples, absent confidence intervals, and undefined minimally important differences. Overall certainty was low–moderate for educational outcomes and low for clinical endpoints.
Conclusions
VR-RSS improves proximal nonvirtual technical performance and merits integration within structured curricula. Claims of equivalence to nonvirtual training and of patient-level benefit remain provisional. Preregistered, adequately powered trials with blinded, standardized nonvirtual endpoints and explicit decision thresholds are needed to establish educational and clinical value.
