“…Specifically, Kirkpatrick classifies studies on 4 levels: (1) reaction, (2) learning, (3) behavior, and (4) results. 5 The study by Pezel et al 1 provides information about both level 1 (reaction to training) and level 2 (learning knowledge and skill). While changes were made to the learner's ability to perform TEE using a simulator 3 months after the course, data are not provided about change in the learner's behavior or performance on an actual TEE after the course, nor are there data about clinical outcomes such as patient safety or completeness of subsequent TEEs.…”
