ObjectivePerforming a basic perioperative transesophageal echocardiography (TEE) requires 3-dimensional knowledge of cardiac anatomy, psychomotor skills, and image interpretation. Commonly, lectures followed by simulation sequence is used for teaching TEE. Differences may occur among learners when this sequencing of instructional components is altered. The authors investigated the ideal sequence of lectures and simulation in teaching basic perioperative TEE.DesignProspective randomized comparative study.SettingSimulation room in a large academy tertiary care center.ParticipantsNoncardiac anesthesiologists in Singapore with no prior knowledge of TEE.InterventionComparison of acquisition and retention of knowledge and skills between the lecture followed by simulation group (LS) and the simulation followed by lecture (SL) group.Measurements And Main ResultsKnowledge was assessed using multiple-choice questions (MCQs) and skills using a skill test. The primary outcome measured was the MCQ scores (post-course and retest) and the skill test scores (post-course and retest). Of the 43 anesthesiologists who were recruited, 22 were randomized into the LS group and 21 to the SL group. All participants took pre-course and post-course MCQs and post-course skill tests. Post-tests were repeated 1 month after the course to assess retention. There was no significant difference in the post-course MCQ (85.87% v 81.82%) and skill test scores (85.78% v 81.55%) between the SL and LS groups, respectively. The SL group demonstrated significantly better retention of knowledge at 1 month (MCQ score 83.5% v 72.73%; p = 0.003) and skills (skill test score 85.32% v 1.90%; p = 0.016) than the other.ConclusionThis study showed that, for retention (at 1 month) of both knowledge and skills, it is preferable to teach practical skills followed by theoretical knowledge to anesthesiologists who are complete novices to TEE.Copyright © 2019 Elsevier Inc.
