Developing assessments of surgical skills for the GMC Performance Procedures.

Abstract

The objectives were to: (i) establish how 'typical' consultant surgeons perform on 'generic' (non-specialist) surgical simulations before their use in the General Medical Council's Performance Procedures (PPs); (ii) measure any differences in performance between specialties; and (iii) compare the performance of group of surgeons in the PPs with the 'typical' group. Seventy-four consultant volunteers in gastrointestinal surgery (n=21), vascular surgery (n=11), urology (n=10), orthopaedics (n=15), cardiothoracic surgery (n=10) and plastic surgery (n=7), plus 9 surgeons undertaking phase 2 of the PPs undertook 7 simple simulations in the skills laboratory. The scores of the volunteers were analysed by simulation and specialty using ANOVA. The scores of the volunteers were then compared with the scores of the surgeons in the PPs. There were significant differences between simulations, but most volunteers achieved scores of 75-100%. There was a significant simulation by specialty interaction indicating that the scores of some specialties differed on some simulations. The scores of the group of surgeons in the PPs were significantly lower than the reference group for most simulations. Simple simulations can be used to assess the basic technical skills of consultant surgeons. The simulation by specialty interaction suggests that whilst some skills may be generic, others are not. The lower scores of the surgeons in the PPs suggest that these tests possess criterion validity, i.e. they may help to determine when poor performance is due to lack of technical competence.
