Objective:
The assessment of surgical technical skills has become an important topic in recent years. This study presents the validation of a 6-task skills examination for junior surgical trainees (at the level of the Membership of the Royal College of Surgeons).
Summary Background Data:
Six tasks were evaluated in a project that also examined the feasibility of this method of assessment. The tasks were knowledge of sutures and instruments; knowledge of surgical devices; knot formation; skin-pad suturing, closure of an enterotomy; excision of a skin lesion; and laparoscopic manipulation. Comparisons were made between a group of junior trainees (n = 13), and a group of seniors (n = 8).
Results:
Each of the 6 tasks was able to be used to discriminate between the 2 groups. In all, there were 19 primary analyses across the 6 tasks, and 17 of these showed significant differences between the groups (P values ranging from 0.037 to < 0.001). There was generally a strong correlation between the analyses, and when a mean rank was calculated, the difference between groups was significant (P = 0.005 on Mann-Whitney U test; mean ranks 13.9 and 6.3 [of 21], for juniors and seniors respectively). Reliability of the 6-task assessment was very good at 0.70 (Cronbach's Alpha).
Conclusions:
A skills examination is a feasible and effective method of assessing the technical ability of basic surgical trainees.
