Innovation Concet : 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 high-fidelity simulator.  Methods : Emergency medicine residents with no prior TEE experience that were rotating through a university-affiliated emergency department 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 as determined by two blinded reviewers using an anchored scoring tool. Secondary outcomes included time to scan completion and diagnostic accuracy on the transfer test. Assessment scores were compared using a two-tailed t-test.  Curriculum, Tool or Material : 22 of 25 (88%) of invited residents agreed to participate in the study. Percentage of successful views increased from 44.5% (SD 27.9) at baseline to 98.6% (SD 3.5) after training (p &amp;lt; 0.001), and was 86.8% (SD 12.1) on transfer testing (p &amp;lt; 0.001). Time to complete the scan was 330 seconds at baseline, 125 seconds after training (p &amp;lt; 0.001), and 184 seconds (p &amp;lt; 0.001) in the transfer test. Participants made the correct diagnosis in 75% (SD 25.6) of the cases in the simulated patient encounter. The descending aorta view had the highest success rate (93.2%) and the midesophageal long axis view had the lowest success rate (75.0%).  Conclusion : A brief simulation-based workshop was effective for teaching emergency medicine residents a five-view resuscitative TEE protocol. Future studies are needed to determine optimal methods for long-term skill retention.
