A Novel Rating System Effectively Differentiates Resident Surgical Performance on a Gastrectomy Animal Model

INTRODUCTION: Current evaluation of trainee operative performance is based on overall impressions and rarely involves objective rating systems. We hypothesized that a new rating system would objectively differentiate between residents of variable surgical skill performing a series of standardized operative steps.
METHODS: Upper level residents were instructed using an open Billroth II porcine gastrectomy model. The procedure was deconstructed into a series of discrete steps and a standardized reporting form was developed for performance evaluation of each step by a trained observer using Likert scales for different components of the procedure.
RESULTS: Two residents injured the common bile duct during division of the proximal duodenum and these were scored as major errors. Resident task performance was divided into thirds for the purpose of analysis. The table shows that the difference in scores between the Top, Middle and Bottom performing residents was highly significant (p
