Ex vivo technical skills training transfers to the operating room and enhances cognitive learning: a randomised controlled trial. Ann Surg 2011; 253: 886–889.

Published: 27th September 2011

Authors: Palter VN, Grantcharov T, Harvey A, Macrae HM.

Conclusion

Eighteen inexperienced trainees were taught the basics of fascial closure, and practised once on a low technology model. Half were randomly allocated to continue practise with the model until they were proficient: this group performed significantly better when the technique was taken in vivo (P=0.04).
