Subclaims¶

q2 i? An RCT found significantly lower mean error counts in the VRT group than the NAT group (1.19 versus 7.38, Z = −2.76, P < 0.006, Mann–Whitney U test). → Humm Gemma; Mohan Helen Peter; Fleming Christina; Harries Rhiannon; Wood Christopher; Dawas Khaled; Stoyanov Danail; Lovat Laurence B 2022 q2 i? An RCT of the first 10 operating-theatre cases found the VRT group made fewer intraoperative errors than the NAT group (mean 28.4 versus 86.2, P = 0.0037). → Humm Gemma; Mohan Helen Peter; Fleming Christina; Harries Rhiannon; Wood Christopher; Dawas Khaled; Stoyanov Danail; Lovat Laurence B 2022 (2)

q2 · i? · quant-synthesis · r3

Single-centre two-arm RCT randomizing 16 participants to VR training or no additional training, assessed on an ex vivo porcine model in a box trainer; "1.19 versus 7.38, Z = −2.76, P < 0.006 Mann–Whitney U test". Gallbladder injury and burns were five times more likely in the NAT group.

"There were statistically significant differences in mean error counts between the VRT and NAT groups (1.19 versus 7.38, Z = −2.76, P < 0.006 Mann–Whitney U test)"

q2 · i? · quant-synthesis · r3

Single-centre two-arm RCT randomizing 13 participants to VR training or no additional training, assessing the first 10 laparoscopic cholecystectomies in the operating theatre (37 procedures in total); "mean 28.4, 95 per cent c.i. 23.51 to 33.32 versus mean 86.2, 95 per cent c.i. 58.18 to 114.12, P = 0.0037". No significant difference in intraoperative phase analyses.

"Significant differences were found in mean error counts between the VRT group, who made fewer intraoperative errors, compared with the NAT group (mean 28.4, 95 per cent c.i. 23.51 to 33.32 versus mean 86.2, 95 per cent c.i. 58.18 to 114.12, P = 0.0037)35"
