Abstract 11964: Implementation of a Near Peer ECG Didactic Curriculum in an Internal Medicine Residency Program

Abstract

Introduction: Electrocardiogram (ECG) interpretation is a fundamental skill. Near-peer teaching improves knowledge acquisition and learner satisfaction. We previously demonstrated an improvement in resident comfort level in interpreting ECGs following structured didactics. Here, we aim to establish whether a longitudinal didactic curriculum objectively increases resident performance in ECG interpretation. Methods: This prospective cohort study surveyed Internal Medicine residents at University at Buffalo who participated in monthly ECG didactics over a 7-month period. Pre- and post-curriculum surveys were administered. Responses were anonymous and participation voluntary. Data collected included demographics, attendance, exposure to clinical cardiology, interest in cardiology, and number of sessions attended. Residents were asked to interpret sixteen unique ECGs, divided evenly among eight common rhythms into both surveys. Fall 2021 and Spring 2022 cohorts were compared using t-tests and chi-square analyses. Associations between attendance, comfort level in interpretation, and number of correct interpretations were analyzed using Pearson correlations. Multivariate linear regression determined the strongest predictor of the number of correct ECG interpretations. Results: Spring cohort correctly interpreted a significantly greater percentage of ECGs than Fall cohort (74.5% vs. 60.9% , p < 0.001). Didactic attendance was significantly associated with comfort level in interpreting ECGs (r = .328, p = .018) and a showed trend towards increased number of correct interpretations (r = .248, p = .077). Attending three or more sessions resulted in a greater percentage of correct ECG interpretations compared to those who attended two or fewer sessions (80.0% vs. 71.1%, p = 0.48). Number of clinical cardiology blocks taken was significantly associated with correct interpretations (r = .310, p < .001) and was the strongest predictor of accurately interpreting ECGs (β = 0.29, p = .037). Conclusions: Dedicated ECG didactics improve residents’ ability to interpret ECGs. A longitudinal curriculum which contains both didactic sessions and clinical exposure appears to offer the greatest benefit in improving ECG interpretation skills.
