Ideal Sequence of Didactic Lectures and Simulation in Teaching Transesophageal Echocardiography Among Anesthesiologists

Transformative Learning, Priming, and Simulation Timing: A Randomized Controlled Pilot Study Among Emergency Medicine Residents

Background Traditionally, learning is thought to occur best when prerequisite cognitive background information is delivered before simulation training. More recent studies have attempted to analyze the transformative nature of simulation by placing simulation before didactics. However, these studies were flawed as they provided background on the subject before the simulation itself. Our study aims to isolate the transformative effect of simulation and answer the question of whether lecture or simulation should come first. Methodology We designed a novel simulation session and accompanying lecture for 18 Emergency Medicine residents in all three years of training regarding a subject they were entirely unfamiliar with, the emergent management of a left ventricular assist device (LVAD). The residents were randomized into two groups. One group had the lecture (8/18) before their simulation, while the other group (10/18) had the simulation first and the lecture afterward, testing the motivational nature. Thereafter, both groups responded to a post-session survey with Likert-style and open-ended comment questions to assess the reaction to the session and a knowledge-based multiple-choice question test. Results Both groups did not score significantly differently on either the immediate post-test or a retention post-test that we administered four weeks later. Three of eight participants reported in open comments that they were much more comfortable with a lecture-first than a simulation-first format. Conclusions Despite controlling for some of the limitations of previous studies, our results including learners' preferences do not support a transformation in the sequence of clinical skills learning. Until other larger studies prove the opposite, we recommend continuing with the lecture followed by the simulation sequence as per existing conceptual simulation learning frameworks.

An Innovative Curriculum For Teaching Transesophageal Echocardiography (TEE) to Emergency Medicine Residents

BACKGROUND

Focused transesophageal echocardiogram (TEE) can be a valuable tool for emergency physicians (EP) during cardiac arrest.

OBJECTIVES

We sought to demonstrate the ability of emergency medicine (EM) residents without prior TEE experience to perform a simulated four-view TEE following a short, flipped conference curriculum.

METHODS

This was a prospective, simulation-based study where EM residents participated in the following four-view TEE curriculum: 1 h of online content reviewed prior to a 20-min in-person lecture and 30-min hands-on practice using a TEE trainer. Each resident attended four testing sessions over an 8-week period and performed a total of 25 TEE scans. Each TEE scan was graded in real time using a 10-point checklist by a TEE-credentialed EP. Interrater reliability of the checklist was calculated using the kappa coefficient (κ). A random sample of 10% of the TEE scans were reviewed by a TEE expert using a standard ultrasound 1-5 scale for image acquisition quality, with a "3" considered to be satisfactory. Residents completed an online pretest and posttest.

RESULTS

Twenty-four residents participated. Mean pre- and posttest scores were 52% (SD 16) and 92% (SD 12), respectively. Mean TEE scores using the 10-point checklist after sessions one and four were 9.4 (SD 0.4) and 9.7 (SD 0.3), respectively. Mean time to complete each TEE scan after sessions one and four were 118.1 (SD 28.3) and 57.1 (SD 17.0) s, respectively. The κ for the checklist was 1. The median score for the image acquisition review was 3 (interquartile range 3-4).

CONCLUSIONS

This simplified flipped conference curriculum can train EM residents to competently perform TEE in a simulated environment.

Simulation-based training following a theoretical lecture enhances the performance of medical students in the interpretation and short-term retention of 20 cross-sectional transesophageal echocardiographic views: a prospective, randomized, controlled trial

Background

Both simulation-based training and video-based training serve as educational adjuncts for learning TEE among medical students. In the present study, we hypothesized that simulation-based training would better enhance the performance of medical students in the interpretation of 20 cross-sectional views compared to video-based training.

Methods

A total of 120 4th-year undergraduate medical students were enrolled in the present study. The study began with a pre-test of all the participants, followed by a 90-min theoretical lecture and a post-test. Subsequently, the participants were randomly divided into the video-based group (Group V) and simulation-based group (Group S). Next, Group V received 60 min of TEE video learning, while Group S received 60 min of TEE simulator training. After the respective training, both the groups undertook the retention-test 1 and retention-test 2, 1 week and 1 month later, respectively. The performance for each test was evaluated by five views, which were selected randomly and, respectively, from a set of 20 cross-sectional views. The primary outcome was the performance of the retention-test 1. Secondary outcomes included: (1) comparison the performances of the pre-test, post-test, and retention-test 2 between two groups; (2) comparison the performances of pre-test and post-test in the same group; (3) comparison the performances of retention-test 1, and retention-test 2 in the same group.

Results

Better performances were observed in Group S in both retention-test 1 (Group V: 63.2 [52.6, 77.6] vs. Group S: 89.5 [68.4, 100.0], P < 0.001) and retention-test 2 (Group V: 58.0 [48.0, 72.0] vs. Group S: 74.0 [64.0, 80.0], P < 0.001) compared to Group V. No statistically significant differences were observed in the performances of pre-test (Group V: 8.3 [4.2, 12.5] vs. Group S: 8.3 [4.2, 12.5], P = 0.825) or post-test (Group V: 46.2 [38.5, 57.7] vs. Group S: 44.2 [38.5, 56.7], P = 0.694) between the two groups. The improvement had been observed in the post-test, compared with pre-test in the same group, respectively (Group V in post-test: 46.2 [38.5, 57.7] vs. Group V in pre-test: 8.3 [4.2, 12.5], P < 0.001; Group S in post-test: 44.2 [38.5, 56.7] vs. Group S in pre-test: 8.3 [4.2, 12.5], P < 0.001). However, the performance in retention-test 2 was significantly reduced, compared with retention-test 1 in the same group, respectively (Group V in retention-test 2: 58.0 [48.0, 72.0] vs. Group V in retention-test 1: 63.2 [52.6, 77.6] P = 0.005; Group S in retention-test 2: 74.0 [64.0, 80.0] vs. Group S in retention-test 1: 89.5 [68.4, 100.0], P < 0.001).

Conclusions

Following a 90-min theoretical lecture, simulation-based training better enhanced the performance of medical students in the interpretation and short-term retention of 20 cross-sectional views compared to video-based training.

Rational and Design of the SIMULATOR Study: A Multicentre Randomized Study to Assess the Impact of SIMULation-bAsed Training on Transoesophageal echocardiOgraphy leaRning for Cardiology Residents

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. 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 non-randomized 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.

Training and Accreditation Pathways in Critical Care and Perioperative Echocardiography

In recent years, there has been a dramatic rise in the use of echocardiography in perioperative and critical care medicine. It is now recommended widely as a first-line diagnostic tool when approaching patients in shock, due to its ability to identify shock etiology and response to treatment noninvasively. To match the increasing training demand, and to ensure maintenance of high-quality and reproducible scanning, several accreditation pathways have been developed worldwide. Critical care echocardiography training pathways can include both transthoracic and transesophageal scanning and range from basic focused protocols to advanced comprehensive scans. The complexity of each individual training program is reflected in its accreditation process. While basic accreditations may require only course attendance and a relatively brief logbook, comprehensive accreditations often require extensive logbooks and written and practical examinations. Currently, the use of transoesophageal echocardiography remains restricted largely to cardiothoracic anesthesia and critical care; however, its use in the general intensive care setting is growing. This narrative review summarizes the most common training pathways, their curricula, and accreditation requirements. The authors initially focus on echocardiography training in the United Kingdom, and then go on to describe similar international accreditations available in Europe, North America, and Australasia.

A BEME systematic review of teaching interventions to equip medical students and residents in early recognition and prompt escalation of acute clinical deteriorations: BEME Guide No. 62

Background: Current educational interventions and teaching for acute deteriorations seem to address acute care learning in discreet segments. Technology enhanced and team training methodologies are in vogue though well studied in the nursing profession, teaching avenues for junior 'doctors in training' seem to be a lacuna.Aims: The BEME systematic review was designed to (1) appraise the existing published evidence on educational interventions that are intended for 'doctors in training' to teach early recognition and prompt escalation in acute clinical deteriorations (2) to synthesise evidence & to evaluate educational effectiveness.Methodology: The method applied was a descriptive, justification & clarification review. Databases searched included PubMed, PsycINFO, Science Direct and Scopus for original research and grey literature with no restrictions to year or language. Abstract review, full text decisions and data extraction were completed by two primary coders with final consensus by a third reviewer.Results: 5592 titles and abstracts were chosen after removal of 905 duplications. After exclusion of 5555 studies, 37 full text articles were chosen for coding. 22 studies met final criteria of educational effectiveness, relevance to acute care. Educational platforms varied from didactics to blended learning approaches, small group teaching sessions, simulations, live & cadaveric tissue training, virtual environments and insitu team-based training. Translational outcomes with reduction in long term (up to 3-6 years) morbidity & mortality with financial savings were reported by 18% (4/22) studies. Interprofessional training were reported in 41% (9/22) of studies. Recent evidence demonstrated effectiveness of virtual environment and mobile game-based learning.Conclusions: There were significant improvements in teaching initiatives with focus on observable behaviours and translational real patient outcomes. Serious game-based learning and virtual multi-user collaborative environments might enhance individual learners' cognitive deliberate practice. Acute care learning continuum with programmatic acute care portfolios could be a promise of the future.
