Subclaims¶

q3 i2 In a meta-analysis of nine RCTs, average final performance scores were significantly higher for VBC participants than controls (SMD 0.71, 95% CI 0.37–1.04, p < 0.0001). → Anderson Steven Mark 2025

q3 · i2 · quant-synthesis · r3

Meta-analysis of nine RCTs reporting final performance scores, with 94 VBC and 89 control participants; only final OSATS scores were used where multiple assessments existed. The pooled effect size was SMD 0.71 (95% CI 0.37, 1.04), showing scores "significantly higher than the controls".

"Overall, the average performance scores for VBC were significantly higher than the controls, with a SMD of 0.71 (95% CI 0.37, 1.04, Z = 4.15, p < 0.0001, and Figure 3)."

Discussion¶

Related Claims¶

• VBC advantage over controls is largest against no-specific-feedback controls and non-significant against controls receiving supplementary training material — a narrower finding that bears on this claim
• VBC outperforms controls whether delivered in single or multiple sessions and in simulated or live surgery — a narrower finding that bears on this claim
• Video-based coaching produces significantly larger improvement from baseline to final assessment than control feedback — related
• Use of a previously validated coaching model yields significantly higher change scores but not significantly higher final performance scores — related
• The overwhelming majority of VBC participants across the studies found VBC a useful training tool — related
• VBC session length of over 20 minutes is likely optimal, with shorter sessions more often failing to show significant benefit — related
