Focused Transthoracic Echocardiography Performed and Interpreted by Medical Residents in the Critically Il

Abstract

Purpose. Intensivist-performed focused echocardiography (FE) is accepted practice. Whether medical residents can perform and interpret quality FE in the critically ill is unknown. Methods. Novice residents trained in an 8-hour module in FE, evaluating ejection fraction (EF), pericardial effusion, right ventricular (RV) strain, valvular pathology, wall motion abnormalities (WMAs), and inferior vena cava collapsibility in patients awaiting comprehensive echocardiograms. The Fleiss kappa (κ), sensitivity, specifi city, positive predictive values, and negative predictive values were calculated against the comprehensive echocardiogram. Results. Seven residents performed 102 FE, demonstrating substantial agreement with cardiologists for EF as decreased versus normal or hyperdynamic (κ =.67, P
