Subclaims¶

q2 i3 In meta-analysis of trials assessing objective skill scores, simulation was associated with a large standardized improvement of 1.68 points on a five-point scale. → O'Dwyer M 2022

Evidence¶

O'Dwyer M 2022¶

O'Dwyer M, Fleming CA, Ahern S, Barrett S, Raftery NB, Ní Dhonnchú T, Doddakula K. (2022). Objective improvement with coronary anastomosis simulation training: meta-analysis. BJS Open. https://doi.org/10.1093/bjsopen/zrab147

q2 · i3 · quant-synthesis · r3

Random-effects meta-analysis of seven studies (14 groups) comparing five-point-scale skill scores before versus after simulation. The pooled standardized improvement was "1.68 points" (95 per cent c.i. 1.23 to 2.13; P < 0.001), with I2 = 77 per cent and individual effect sizes from 0.51 to 3.14 points.

"Trainees who used simulation had an associated improvement of 1.68 points (95 per cent c.i. 1.23 to 2.13; P < 0.001) (Fig. 4)."
