An Innovative Curriculum For Teaching Transesophageal Echocardiography (TEE) to Emergency Medicine Residents

Abstract

BackgroundFocused transesophageal echocardiogram (TEE) can be a valuable tool for emergency physicians (EP) during cardiac arrest. ObjectivesWe sought to demonstrate the ability of emergency medicine (EM) residents without prior TEE experience to perform a simulated four-view TEE following a short, flipped conference curriculum. MethodsThis was a prospective, simulation-based study where EM residents participated in the following four-view TEE curriculum: 1 h of online content reviewed prior to a 20-min in-person lecture and 30-min hands-on practice using a TEE trainer. Each resident attended four testing sessions over an 8-week period and performed a total of 25 TEE scans. Each TEE scan was graded in real time using a 10-point checklist by a TEE-credentialed EP. Interrater reliability of the checklist was calculated using the kappa coefficient (κ). A random sample of 10% of the TEE scans were reviewed by a TEE expert using a standard ultrasound 1–5 scale for image acquisition quality, with a “3” considered to be satisfactory. Residents completed an online pretest and posttest. ResultsTwenty-four residents participated. Mean pre- and posttest scores were 52% (SD 16) and 92% (SD 12), respectively. Mean TEE scores using the 10-point checklist after sessions one and four were 9.4 (SD 0.4) and 9.7 (SD 0.3), respectively. Mean time to complete each TEE scan after sessions one and four were 118.1 (SD 28.3) and 57.1 (SD 17.0) s, respectively. The κ for the checklist was 1. The median score for the image acquisition review was 3 (interquartile range 3–4). ConclusionsThis simplified flipped conference curriculum can train EM residents to competently perform TEE in a simulated environment.
