LO23: A brief educational session is effective for teaching emergency medicine residents resuscitative transesophageal echocardiography

Introduction: Resuscitative clinician-performed transesophageal echocardiography (TEE) is a relatively new ultrasound application that has the potential to guide the management of critically ill patients in the emergency department. The objective of this study was to determine the effectiveness of a brief training workshop for teaching a resuscitative TEE protocol to emergency medicine residents using a simulator. Methods: Emergency medicine residents with no prior TEE experience from a university-affiliated hospital were invited to participate in the study. Participants completed a questionnaire and baseline skill assessment using a high-fidelity simulator. The training session included a 20-minute lecture followed by 10 simulated repetitions of a 5-view TEE sequence with instructor feedback. Learning was evaluated by a skill assessment immediately after training and a transfer test 1-2 weeks after the training session. Ultrasound images and transducer motion metrics were captured by the simulator for blinded analysis. The primary outcome of this study was the percentage of successful views before and after training. Secondary outcomes included confidence level, image quality, percentage of correct diagnoses, and efficiency of movement. Assessment scores were compared using a two-tailed t-test. Results: 10 of 11 (91%) of invited residents agreed to participate in the study. Confidence level on a 10-point numeric rating scale (NRS) increased from a baseline of 1.0 (SD 0) to 7.0 (SD 1.9) after training (p
