Making the Best Residency Program: Incorporating a Business Model of Improvement to General Surgery Residency

Abstract

INTRODUCTION: Cumulative Sum (CuSum) is a real-time proficiency-monitoring tool adapted for simulation-based training. This study's purpose was to investigate long-term effects of a randomized prospective trial conducted on medical students assessing CuSum-guided curriculum against volume-based standards. METHODS: Prior study participants completed a survey assessing confidence, exposure, and feedback at 12 to 18 months post trial completion. They underwent triplicate testing of suturing, intubation, and central line placement (CVC), which was video-recorded and assessed by an expert evaluator. Baseline characteristics among repeat subjects were compared using chi-square tests. Retention and initial trial outcomes were compared using parametric statistical methods and linear regression to control for confounders.
