Purpose: Optimal instruction and assessment of critical care ultrasound (CCUS) skills requires an assessment tool to measure learner competency and changes over time. In this study, a previously published tool was used to monitor the development of critical care echocardiography (CCE) competencies, the attainment of performance plateaus, and the extent to which previous experience influenced learning.

Materials And Methods: A group of experts used the Rapid Assessment of Competency in Echocardiography (RACE) scale to rate a large pool of CCE studies performed by novices in a longitudinal design.

Objectives: Increased use of point-of-care ultrasound (US) requires the development of assessment tools that measure the competency of learners. In this study, we developed and tested a tool to assess the quality of point-of-care cardiac US studies performed by novices.

Methods: In phase 1, the Rapid Assessment of Competency in Echocardiography (RACE) scale was developed on the basis of structured interviews with subject matter experts; the tool was then piloted on a small series of US studies in phase 2.

Background: Emergency physicians frequently employ transthoracic echocardiography (TTE) to assist in diagnosis and therapy for patients with circulatory failure or arrest. In critically ill patients, transesophageal echocardiography (TEE) offers several advantages over TTE, including reliable, continuous image acquisition and superior image quality. Despite these advantages, TEE is not widely used by emergency physicians.
