Comparative assessment of surgical training using objective criteria.

The aims of the study were to develop and validate an objective method of assessing the operative experience of surgical trainees. Data were retrieved from a prospectively recorded computer database of operating activity in a single surgical unit over a three-year period. Operations were weighted using intermediate equivalent (IE) values. The number of operations performed (caseload), IE workload, consultant involvement and a subjective assessment of operative ability by consultant was obtained for each of 3 SHO IIIs and 7 SHO Is. The total caseload correlated poorly with subjective grading. The total workload correlated well with the subjective assessment of the SHO IIIs and, excluding minor operations, with the SHO Is. SHO IIIs' workload consisted of a higher number of more complex procedures than SHO Is' and for both types of trainee the degree of complexity increased during the tenure of each one year post. A consultant was the assistant in 50 per cent of the intermediate and major operations performed by the SHO Is in the first quarter of each one year post dropping to 30 per cent in the remaining three-quarters. In conclusion an objective assessment was easily obtained and interpreted. Similar data from other surgical units are required to place this work in perspective and to allow formulation of guidelines.
