Abstract Background Point-of-care ultrasound is becoming a ubiquitous diagnostic tool, and there has been increasing interest to teach novice practitioners. One of the challenges is the scarcity of qualified instructors, and with COVID-19, another challenge is the difficulty with social distancing between learners and educators. The purpose of our study was to determine if ultrasound-naïve operators can learn ultrasound techniques and develop the psychomotor skills to acquire ultrasound images after reviewing SonoSim® online modules. Methods This was a prospective study evaluating first-year medical students. Medical students were asked to complete four SonoSim® online modules (aorta/IVC, cardiac, renal, and superficial). They were subsequently asked to perform ultrasound examinations on standardized patients utilizing the learned techniques/skills in the online modules. Emergency Ultrasound-trained physicians evaluated medical students’ sonographic skills in image acquisition quality, image acquisition difficulty, and overall performance. Data are presented as means and percentages with standard deviation. All P values are based on 2-tailed tests of significance. Results Total of 44 medical students participated in the study. All (100%) students completed the hands-on skills evaluation with a median score of 83.7% (IQR 76.7–88.4%). Thirty-three medical students completed all the online modules and quizzes with median score of 87.5% (IQR 83.8–91.3%). There was a positive association between module quiz performance and the hands-on skills performance (R-squared = 0.45; p < 0.001). There was no statistically significant association between module performance and hands-on performance for any of the four categories individually. In all four categories, the evaluators’ observation of the medical students’ difficulty obtaining views correlated with hands-on performance scores. Conclusions Our study findings suggest that ultrasound-naïve medical students can develop basic hands-on skills in image acquisition after reviewing online modules.

Abstract Background Cardiac point-of-care ultrasound (POCUS) training has been integrated into medical school curricula. However, there is no standardized cardiac POCUS training method for medical students. To address this issue, the American Society of Echocardiography (ASE) proposed a framework for medical student cardiac POCUS training. The objective of this pilot study was to develop a medical student cardiac POCUS curriculum with test scoring systems and test the curriculum feasibility for a future definitive study.Methods Based on the ASE-recommended framework, we developed a cardiac POCUS curriculum consisting of a pre-training online module and hands-on training with a hand-held ultrasound (Butterfly iQ). The curriculum learning effects were assessed with a 10-point maximum skill test and a 40-point maximum knowledge test at pre-, immediate post-, and 8-week post-training. To determine the curriculum feasibility, we planned to recruit 6 pre-clinical medical students. We semi-quantitatively evaluated the curriculum feasibility in terms of recruitment rate, follow-up rate 8 weeks after training, instructional design of the curriculum, the effect size (ES) of the test score improvements, and participant satisfaction. Discriminatory ability of the test scoring systems were assessed by comparing the scores of the medical students, medical interns, and experts.Results Six pre-clinical medical students participated in the curriculum. The recruitment rate was 100% (6/6 students) and the follow-up rate 8 weeks after training was 100% (6/6). ESs of skill and knowledge test score differences between pre- and immediate post-, and between pre- and 8-week post-training were large. The students reported high satisfaction with the curriculum. The test scoring systems demonstrated excellent discriminatory ability between the 3 different performance levels.Conclusions This pilot study confirmed the curriculum design as feasible with instructional design modifications including the hands-on training group size, content of the cardiac POCUS lecture, hands-on teaching instructions, and hand-held ultrasound usage. Based on the pilot study findings, we plan to conduct the definitive study with the primary outcome of long-term skill retention 8 weeks after initial training. The definitive study has been registered in ClinicalTrials.gov (Identifier: NCT04083924).

Abstract Background Point-of-care ultrasound (POCUS) is becoming widely adopted with increasing accessibility of courses. Little is known about the optimal design of the introductory course or longitudinal training programs targeting hospitalists that are critical to success. Methods Hospitalists at four academic sites participated in a two-day introductory course and a longitudinal phase comprising clinical POCUS practice, clip uploading with online feedback, hands-on teaching, and monthly ultrasound conferences. Assessments were performed immediately before and after the two-day course and after 1 year. Results Knowledge increased from baseline to post two-day course (median score 58 and 85%, respectively, p < 0.001) and decreased slightly at 1 year (median score 81%, p = 0.012). After the two-day introductory course, the median score for hands-on image acquisition skills, the principal metric of participant success, was 75%. After 1 year, scores were similar (median score 74%). Confidence increased from baseline to post two-day course (1.5 to 3.1 on a 4 point Likert scale from Not at all confident (1) to Very confident (4), p < 0.001), and remained unchanged after 1 year (2.73). Course elements correlating with a passing score on the final hands-on test included number of clip uploads (r = 0.85, p,0.001), attendance at hands-on sessions (r = 0.7, p = 0.001), and attendance at monthly conferences (r = 0.50, p = 0.03). Conclusions The I-ScaN POCUS training program increased hospitalist knowledge, skill and confidence with maintained skill and confidence after 1 year. Uploading clips and attending hands-on teaching sessions were most correlative with participant success.

Introduction: Point of care ultrasound for assessment of undifferentiated hypotension and shock is part of the clinical scope of Emergency Physicians in Canada. The RUSH Exam outlines a systematic approach to these patients. A RUSH Exam educational model using didactic and hands on practice was developed and implemented for Emergency Medicine (EM) residents. This study evaluated the effectiveness of the module in a simulated setting on the following endpoints: improvement in image acquisition, interpretation, speed, and subjective comfort level, among EM residents with basic ultrasound training. Methods: Approval was received from the institutional health research ethics board for this before and after simulation study. Residents in the -EM Program or CCFP-EM Program from July 2014 to July 2015 were eligible to consent. Participants were excluded if they were unable to complete all portions. All residents were educated to the same level of introductory ultrasound training based on the curriculum in place at our institution. The 8-hour intervention included RUSH didactic and hands on small group sessions. Testing before and after the intervention was performed with the SonoSim Livescan training platform. Two evaluators scored each resident on the accuracy of image acquisition, image interpretation, and time to scan completion. A before and after survey assessed resident comfort level with performing ultrasound on an emergency patient in shock, and basing decisions on ultrasound findings. Statistical analysis was performed using McNemar’s test for image acquisition and interpretation, a paired T test for time, and the Bahpkar test for the questionnaire. Results: 16 EM residents including 11 senior residents and 5 junior residents were enrolled. Improvement was achieved in the categories of IVC image acquisition and interpretation, as well as interpretation for B-lines, lung sliding, cardiac apical and parasternal long axis, and DVT (p<0.05). Subjective comfort level of performing ultrasound in shock and basing decisions on the findings was increased (p<0.0001). Among junior residents, there was an increased speed of image acquisition. Conclusion: With the introduction of the RUSH Exam educational module, EM residents showed improved image acquisition, image interpretation, speed, and comfort level when using ultrasound in critically ill patients.

BACKGROUND Teaching medical ultrasound (US) has gained in popularity in medical schools. Hands-on workshops are an essential part of teaching. The lockdown induced by COVID-19 kept our medical school from conducting these workshops. OBJECTIVE The aim of this paper is to describe an alternative method we used to allow our students to acquire the essential psychomotor skills requisite to produce US images. METHODS Our students should study online US courses. After this study, they had to practice exercises on a virtual simulator, using the mouse of their computer to control a simulated transducer. We measured the precision reached at the completion of simulation exercises. Before and after completion of the courses and simulator’s exercises, students had to complete a questionnaire dedicated to psychomotor skills. A general evaluation questionnaire was also submitted. RESULTS One hundred and ninety three students returned the pre-course questionnaire. One hundred and eighty four performed all the simulator exercises and 181 answered the post-course questionnaire. One hundred and ninety general evaluation questionnaires were sent and 136 returned (76%). The average pre-course score was 4.23 (SD 2.14), after exercising, the average post-course score was 6.36 (SD 1.82), with a significant improvement (p< .001). The post-course score was related to the accuracy with which the simulator exercises were performed (Spearman's rho 0.2664, p< 0.01). Nearly two-thirds (62.6%) of the students said they enjoyed working on the simulator. Seventy-nine (58.0%) students felt that they had achieved the course's objective of reproducing ultrasound images. Inadequate connection speed had been a problem for 40.2% of students. CONCLUSIONS The integration of an online simulator for the practical learning of US in remote mode has allowed substantial acquisitions in the psychomotor field of US diagnosis. Despite the absence of workshops, the students were able to learn and practice how to handle an US probe in order to reproduce standard images. CLINICALTRIAL Not considered as a RCT by our ethics committee (Req-2021-00589)

Purpose: This study aimed to assess the impact of ultrasound simulation (SonoSim) on educational outcomes of an introductory point-of-care ultrasound course compared to hands-on training with live models alone. Methods: Fifty-three internal medicine residents without ultrasound experience were randomly assigned to control or experimental groups. They participated in an introductory point-of-care ultrasound course covering eight topics in eight sessions from June 23, 2014 until July 18, 2014. Both participated in lecture and hands-on training, but experimental group received an hour of computerized simulator training instead of a second hour of hands-on training. We assessed clinical knowledge and image acquisition with written multiple-choice and practical exams, respectively. Of the 53 enrolled, 40 participants (75.5%) completed the course and all testing. Results: For the 30-item written exam, mean score of the experimental group was 23.1±3.4 (n=21) vs. 21.8±4.8 (n=19), (P>0 .05). For the practical exam, mean score for both groups was 8.7 out of 16 (P>0 .05). Conclusion: The substitution of eight hours of ultrasound simulation training for live model scanning in a 24 hour training course did not enhance performance on written and image acquisition tests in an introductory ultrasound course for residents. This result suggests that ultrasound simulation technology used as a substitute for live model training on an hour-for-hour basis, did not improve learning outcomes. Further investigation into simulation as a total replacement for live model training will provide a clearer picture of the efficacy of ultrasound simulators in medical education.

As point of care ultrasound (PoCUS) becomes increasingly popular and a standard of care in many clinical settings, the interest for integration in medical undergraduate curriculum is also growing [1]. This project aims to assess whether formal bedside Focused Abdominal Scan for Trauma (FAST) exam training of medical students increases their knowledge and comfort with the use of bedside ultrasound in a family medicine setting at Queen’s University. Third year medical students (n=18) were recruited to participate in a training session involving a 1-hour online video and 2-hour hands-on session. Knowledge based surveys were completed before and after the training. A survey was completed 4 months after the teaching session evaluating knowledge retention, comfort, and application of skills. Student knowledge of PoCUS and FAST increased and was maintained (pre-training 56%±20%, post-training 82%±10%, p<0.001). Self-evaluation of comfort performing a FAST examination (5-point Likert scale) similarly increased post-training session (pre-training 1.4±0.8, post-training 3.8±0.9, p<0.005), but decreased 4 months later (3±1.2, p<0.005). Students in this study were unanimously interested in ultrasound training and the methods used effectively increased theoretical knowledge and comfort with use. Students did not retain their comfort levels with FAST exam 4 months after the training session, nor did they have the opportunity to utilize the skills learned. Further evidence is required to identify the applicability of these results to undergraduate curriculum development.

Abstract Introduction Point-of-Care Ultrasound (POCUS) has been shown to be a useful adjunct in assessment of various shock states and utilized to guide resuscitative and post-resuscitation de-escalation efforts. POCUS use for guiding resuscitation in burn injured patient has not be described. Objectives characterize the use of bedside ultrasound examinations performed by advance practice providers and treating physicians in a regional burn intensive care unit Methods Daily beside ultrasound examinations were performed utilizing a bedside ultrasound device by an advanced practice provider prior to rounds POCUS examinations consist of: Ultrasound images were archived to a centralized image repository and reviewed daily during multi-disciplinary rounds. Ultrasonographic volume assessment compared to clinical volume assessment made during daily multidisciplinary rounds. Results 100 examinations were performed of those 32 were within the initial 72 hour window: Conclusions Our results demonstrate that bedside ultrasound aides in guidance of both resuscitative and post-resuscitative efforts. We identified a cohort of patients who appeared hypervolemic clinically but US findings supported hypovolemia, we refer to as pseudohypervolemia US volume assessment provides information that changes management. We believe point of care ultrasound is a viable tool in preventing over-resuscitation as well as to guide post-resuscitative diuresis.

Current experience suggests that artificial intelligence (AI) and machine learning (ML) may be useful in the management of hospitalized patients, including those with COVID-19. In light of the challenges faced with diagnostic and prognostic indicators in SARS-CoV-2 infection, our center has developed an international clinical protocol to collect standardized thoracic point of care ultrasound data in these patients for later AI/ML modeling. We surmise that in the future AI/ML may assist in the management of SARS-CoV-2 patients potentially leading to improved outcomes, and to that end, a corpus of curated ultrasound images and linked patient clinical metadata is an invaluable research resource.
