INTRODUCTION: Simulation-based training in transesophageal echocardiography (TEE) seems promising. However, data are limited to non-randomized or single-center studies. To assess the impact of simulation-based vs. traditional teaching on TEE knowledge and performance for medical residents in cardiology. Pezel et al. SIMULATOR Study: TEE Simulation Training.
MATERIALS AND METHODS: Nationwide prospective randomized multicenter study involving 43 centers throughout France allowing for the inclusion of >70% of all French cardiology residents. All cardiology residents naive from TEE will be included. Randomization with stratification by center will allocate residents to either a control group receiving theoretical knowledge by e-learning only, or to an intervention group receiving two simulation-based training sessions on a TEE simulator in addition.
RESULTS: All residents will undergo both a theoretical test (0–100 points) and a practical test on a TEE simulator (0–100 points) before and 3 months after the training. Satisfaction will be assessed by a 5-points Likert scale. The primary outcomes will be to compare the scores in the final theoretical and practical tests between the two groups, 3 months after the completion of the training.
CONCLUSION: Data regarding simulation-based learning in TEE are limited to nonrandomized or single-center studies. The randomized multicenter SIMULATOR study will assess the impact of simulation-based vs. traditional teaching on TEE knowledge and performance for medical residents in cardiology, and whether such an educational program should be proposed in first line for TEE teaching.
Does the virtual simulation training improve the learning of pelvic ultrasound performed in gynecological emergencies?

OBJECTIVES: To compare the contribution of training using virtual simulation with theoretical instruction alone in the learning of pelvic ultrasound for gynecological emergencies in non‐experienced students.
METHODS: A unicentre randomised controlled trial was conducted. The participants were students in the last year of medical studies during their internship in the obstetrics and gynecology department at the University Hospital Center of Angers. Twenty participants were randomised to a 1:1 ratio in the training group and control group of 10 students each. All participants received a two hours theoretical course on the physical basis of ultrasound, the use of probes, as well as the basic principles of an trans‐vaginal ultrasound examination centreed on the different standardised images to be given to gynecologic emergencies. For the training group an additional 20‐minute pelvic ultrasound training on a trans‐vaginal virtual simulator was performed. The participants were evaluated on images taken from patients consulting our gynecological emergencies centre. The pictures evaluated were sagittal and coronal sections of the uterus, left and right ovarian sections and a Morrison pouch view. The primary outcome was based on picture quality scores described by Salomon et al. with the French Society for the Improvement of Ultrasound Practices (SFAPE) and by Popowski et al. for Standardisation Acute Female Echography (SAFE). Secondaries outcomes focused on the general ultrasound skills and the duration of acquisition of the pictures.
RESULTS: The mean SFAPE and SAFE scores were significantly higher in the training group than in the control group (14.5 ± 3.1, p = 0.046 and 10.1 ± 2.08, p = 0.016, respectively).
CONCLUSIONS: After a very short training session, using virtual simulation, inexperienced students produce proper pictures for the management of gynecological emergencies and better quality ultrasound pictures than students trained only theoretically.

BACKGROUND: Clinical lung ultrasound (LUS) is a fast bedside diagnostic tool which can assist clinicians in decisions regarding the treatment and monitoring of patients with respiratory symptoms. LUS training and education differ widely, and is often done in a clinical setting, with potential risks for patients if decisions are made based on the wrong interpretations. No clear guidelines or recommendations for objective and standardized assessment of LUS skills exist, and those that do are often based on a fixed time-frame or an arbitrary number of examinations performed; this does not ensure adequate competencies.
OBJECTIVES: The study aimed to develop and gather validity evidence for a practical, simulation-based test in LUS.
METHODS: Nine cases were developed in collaboration with Surgical Science Healthcare, representing the most common diagnosis and sonographic findings in patients with respiratory symptoms. Thirty-six participants with different levels of competence in LUS, completed the test. The participants were divided into groups, i.e., novices, intermediates, and experienced, according to their experience with LUS, the number of examinations they had performed, and any research they had conducted. Their answers were used for item analyses.
RESULTS: The intraclass correlation coefficient, Cronbachs’ α, was 0.69 summarized, and there was a statistically significant difference (p < 0.001) between the novices and the trained participants (intermediates and experienced). A pass/fail score of 16 points was calculated according to the contrasting-groups method.
CONCLUSION: We developed a test for the assessment of clinical competencies in LUS. The test proved solid validity evidence, and a pass/fail standard without any false-negatives, and only 2 explained false-positives.

PURPOSE: Critical care transesophageal echocardiography (cTEE) is an important component of advanced critical care echocardiography. Experiential training in cTEE requires greater than 30 real case patients to achieve competence1. The effectiveness of high fidelity TEE simulator (simulator) training to achieve competence is unknown. We studied the effectiveness of using a simulator to train pulmonary/critical care medicine fellows (fellows) in cTEE image acquisition and interpretation.
METHODS: We trained 12 fellows with no experience in cTEE using a simulator. Using a standardized cTEE image acquisition format, trainees performed 14 complete studies, with image acquisition testing on the 15th study. We used a validated system for scoring the operative and interpretive skills of the trainees 2. Once competent on the simulator1, they performed cTEEs under direct attending supervision on patients. Each patient cTEE was graded using the same scoring system as for the simulator. Successful training outcome was defined as a score of >35/401.
RESULTS: Twelve fellows received training with the simulator, consisting of a 3 hour training period. All fellows achieved perfect performance in image acquisition on the simulator at the 15th cTEE study. Eight fellows have further performed at least 5 patient cTEEs. Six fellows achieved a score of >35/40 on their first patient cTEE. The other 2 fellows required an average of 3 studies to achieve a score >35/40.
CONCLUSIONS: Training fellows to perform cTEE using a simulator is effective and may reduce the number of real patient cTEEs needed for training purposes.
CLINICAL IMPLICATIONS: Simulator training can accelerate the training curve for cTEE in fellows. Further studies need to be performed in order to establish the minimum number of cTEEs to be performed to achieve competency. References: 1.Charron, C et al.
