Student-led curricular approaches in medical education: the educational effects of a virtual fundamentals of COVID-19 course.

BACKGROUND: As the field of education was adapting to virtual learning during the COVID-19 pandemic, a need quickly emerged for a course to prepare medical students for future clinical practice. This call to action was answered by creating an innovative Fundamentals of COVID-19 course at the Indiana University School of Medicine (IUSM). As a group of medical student leaders at IUSM, we developed this online course in order to support our fellow students and the community. METHODS: The study examined the educational effects of completing the Fundamentals of COVID-19 course. In order to examine these effects, the study asked enrolled students to complete both a pre- and post-course self-assessment survey. Students were asked an identical set of questions on each survey about their knowledge, skills, and abilities (KSA) regarding COVID-19. Composite scores were created for each KSA learning domain. Responses were provided using a five-point Likert scale ranging from 1 = strongly disagree to 5 = strongly agree. RESULTS: Out of the 724 students enrolled, 645 students completed both the pre- and post-course assessment surveys. Findings show that there were both meaningful and statistically significant differences in students' responses to the pre- and post-course surveys. Results show 1.) a significant mean increase in the knowledge composite score of 1.01, 95% CI [0.95, 1.06], t(644) = 36.4, p < .001, d = 1.43; 2.) a significant mean increase in the skills composite score of .55, 95% CI [0.50, 0.60], t(644) = 20.70, p < .001, d = 0.81. and 3.) a significant mean increase of the abilities composite score of 1.02, 95% CI [.97, 1.07], t(644) = 36.56, p < .001, d = 1.44. CONCLUSIONS: These findings demonstrate that the student-developed, online Fundamentals of COVID-19 course resulted in notable and statistically significant educational effects. The increase in students' self-reported ratings, especially in the knowledge and abilities domains, indicate that meaningful learning occurred within the course. These findings have notable implications for medical student training during healthcare emergencies, such as a pandemic, as well as within modern clerkship environments. Overall, our findings provide evidence that student-led curricular design and virtual delivery of course content can be effective tools in undergraduate medical education.

Integrating evidence-based medicine skills into a medical school curriculum: a quantitative outcomes assessment.

OBJECTIVES: This research project aims to determine the potential differential impact of two curricular approaches to teaching evidence-based medicine (EBM) on student performance on an EBM assignment administered during the first year of clerkship. A meaningful result would be any statistically significant difference in scores on the assignment given to measure student performance. DESIGN: In order to assess and compare student learning under the different curricula, the principal investigator and a team of five faculty members blinded to assignment date and other possibly identifying details used a modified version of the previously validated Fresno rubric to retrospectively grade 3 years' worth of EBM assignments given to students in clerkship rotations 1-3 (n=481) during the Internal Medicine clerkship. Specifically, EBM performance in three separate student cohorts was examined. SETTING: The study took place at a large Midwestern medical school with nine campuses across the state of Indiana. PARTICIPANTS: Study participants were 481 students who attended the medical school and completed the Internal Medicine clerkship between 2017 and 2019. INTERVENTIONS: Prior to the inception of this study, our institution had been teaching EBM within a discrete 2-month time period during medical students' first year. During a large-scale curricular overhaul, the approach to teaching EBM was changed to a more scaffolded, integrated approach with sessions being taught over the course of 2 years. In this study, we assess the differential impact of these two approaches to teaching EBM in the first 2 years of medical school. MAIN OUTCOME MEASURES: We used clerkship-level EBM assignment grades to determine whether there was a difference in performance between those students who experienced the old versus the new instructional model. Clerkship EBM assignments given to the students used identical questions each year in order to have a valid basis for comparison. Additionally, we analysed average student grades across the school on the EBM portion of step 1. RESULTS: Four hundred and eighty-one assignments were graded. Mean scores were compared for individual questions and cumulative scores using a one-way Welch Analysis of Variance test. Overall, students performed 0.99 of a point better on the assignment from year 1 (Y1), prior to EBM curriculum integration, to year 3 (Y3), subsequent to EBM integration (p≤0.001). Statistically significant improvement was seen on questions measuring students' ability to formulate a clinical question and critically appraise medical evidence. Additionally, on the United States Medical Licensing Examination (USMLE) step 1, we found that student scores on the EBM portion of the examination improved from Y1 to Y3. CONCLUSIONS: Results of this study suggest that taking a scaffolded, curriculum-integrated approach to EBM instruction during the preclinical years increases, or at the very least does not lessen, student retention of and ability to apply EBM concepts to patient care. Although it is difficult to fully attribute students' retention and application of EBM concepts to the adoption of a curricular model focused on scaffolding and integration, the results of this study show that there are value-added educational effects to teaching EBM in this new format. Overall, this study provides a foundation for new research and practice seeking to improve EBM instruction. TRIAL REGISTRATION NUMBER: IRB approval (Protocol number 1907054875) was obtained for this study.
