Effects of "minimally invasive curricular surgery" - A pilot intervention study to improve the quality of bedside teaching in medical education

Abstract

Background: Bedside teaching is an important element of undergraduate medical education. However, the impact of curricular course structure on student outcome needs to be determined. Aims: This study assessed changes in fourth-year medical students' evaluations of clinical teaching sessions before and after the introduction of a new course format. Method: The curricular structure of bedside teaching sessions in cardiology was modified without changing the amount of teaching time. Clinical teachers were instructed about the new teaching format and learning objectives. The new format implemented for adult but not paediatric cardiology sessions was piloted with 143 students in winter 2007/08. By computing effect sizes, evaluation results were compared to data obtained from 185 students before the intervention. Results: Significant rating increases were observed for adult cardiology teaching sessions (Cohen's d = 0.66) but not paediatric cardiology sessions (d = 0.22). In addition to improving the structure and organization of the course, the intervention significantly impacted on students' perceptions of their learning outcome regarding practical skills (d = 0.69). Conclusions: Minimal curricular changes combined with basic faculty development measures significantly increase students' perception of learning outcome. Curricular structure needs to be considered when planning bedside teaching sessions in medical undergraduate training.
