Subclaims¶

q3 i? Meta-analysis of three RCTs found OSATS scores significantly higher after VR training than after no additional training (MD 6.22, 95%CI 3.81 to 8.36, P < 0.00001). → Humm Gemma; Mohan Helen Peter; Fleming Christina; Harries Rhiannon; Wood Christopher; Dawas Khaled; Stoyanov Danail; Lovat Laurence B 2022 q2 i? A single-centre RCT of deliberate practice on a VR simulator found significantly higher OSATS scores than conventional residency training (median 17.0 versus 12.5, P = 0.03). → Humm Gemma; Mohan Helen Peter; Fleming Christina; Harries Rhiannon; Wood Christopher; Dawas Khaled; Stoyanov Danail; Lovat Laurence B 2022 (2)

q3 · i? · quant-synthesis · r2

Meta-analysis of three RCTs comparing VR training with no additional training, 59 participants randomized to VRT and 38 to NAT, low heterogeneity (I2 = 23 per cent), fixed-effects model favouring VRT with "MD = 6.22, 95 per cent c.i 3.81 to 8.36, P < 0.00001". No effect size printed.

"In a meta-analysis of three studies33,48,50, 59 participants were randomized to VRT and 38 to NAT. Statistical heterogeneity was low (I2 = 23 per cent). Using a fixed-effects model, the combined weighted effected favoured VR training over NAT (MD = 6.22, 95 per cent c.i 3.81 to 8.36, P < 0.00001)"

q2 · i? · causal · r2

Single-centre RCT randomizing 16 general surgery trainees and residents to conventional residency training or personalized deliberate practice on a VR simulator, assessed in the operating theatre; "median 17.0, i.q.r. 15.3–18.5 versus median 12.5, i.q.r. 7.5–14.0, P = 0.03". Excluded from meta-analysis because training was personalized.

"Significantly higher OSATS score were found in the deliberate practice group compared with the control group (median 17.0, i.q.r. 15.3–18.5 versus median 12.5, i.q.r. 7.5–14.0, P = 0.03)43. This study was excluded from meta-analysis because the VR training received was personalized following assessment and feedback"
