q3 i? Subgroup analyses found no significant differences in final or change scores between single and multiple VBC sessions, or between simulated and live surgical tasks, with VBC significantly better than controls in all these scenarios. → Anderson Steven Mark 2025

Evidence¶

Anderson Steven Mark 2025¶

Anderson Steven Mark, Gillanders Sarahlouise, Hickey Anne, Offiah Gozie, Davis Niall. (2025). Video Killed the Radio Star—A Meta‐Analysis on Video‐Based Coaching to Improve Surgical Skill. World Journal of Surgery. https://doi.org/10.1002/wjs.12494

q3 · i? · quant-synthesis · r3

Subgroup analyses reported in the Results section assessed number of sessions and simulated versus live surgery as potential confounders of the summary effect; VBC remained significantly better than controls in all scenarios, with no subgroup effect sizes printed.

"No significant differences in final performance scores or change scores were seen whether trainees received single or multiple VBC sessions, or whether the surgical task was performed in a simulated setting or during live surgery, with significantly better scores observed in the VBC groups compared to the controls in all these scenarios"
