Abstract Background: Point-of-care ultrasonography (POCUS) is a prompt and simple tool for the urgent diagnosis and treatment of patients in the emergency department (ED). It has contributed to improvements in patient treatment quality, procedural safety, timeliness of care, diagnostic accuracy, and cost reduction. We developed a comprehensive residency-based POCUS training program for ED residents and determined its effect on ultrasound utilization in the ED.Methods: We conducted a retrospective cohort study in the ED of a university-affiliated medical center, evaluating a centralized residency-based POCUS training course from July 2017 to June 2018 for ED residents that included 12 core ultrasound applications: trauma, intrauterine pregnancy, abdominal aortic aneurysm, echocardiography and hemodynamic assessment, hepatobiliary system, urinary tract, deep vein thrombosis, soft tissue and musculoskeletal, thoracic-airway, ocular, bowel, and procedural guidance. Each application comprised a combined lecture and hands-on practice session that lasted for 2 hours. Pre-tests and post-tests, including still image and video interpretation, were performed. Utilization of POCUS among ED residents before and after the POCUS training course (July 2016–June 2017 and July 2018–June 2019) was calculated and analyzed using the Wilcoxon signed-rank test.Results: In total, 16 residents participated and completed the entire training course. The post-test score improved significantly compared to the pre-test score by a median of 12 points (p = 0.04). Utilization of POCUS among the ED residents increased significantly from 0.15 ultrasound studies per patient per year to 0.41 ultrasound studies per patient per year (p < 0.01) after completion of the entire training course. Increased POCUS scanning percentages over the cardiac, soft tissue, abdominal region, vascular system, procedural guidance, and ocular regions were also noted after providing the curriculum.Conclusions: There was a significant increase in POCUS utilization among ED residents after a comprehensive residency-based POCUS training program.

Soft Tissue Infections

Soft tissue ultrasound (ST-USS) has been shown to be of utmost importance in assessing patients with soft tissue infections in the emergency department or critical care unit. It aids in guiding the management of soft tissue infection based on the sonographic findings.

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.

BACKGROUND Lightweight portable ultrasound is widely available, especially in inaccessible geographical areas. It demonstrates effectiveness and diagnosis improvement even in field conditions but no precise information about protocols, acquisition time, image interpretation, and the relevance in changing medical conduct exists. The COVID-19 pandemic implied many severe cases and the rapid construction of field hospitals with massive general practitioner (GP) recruitment. OBJECTIVE This prospective and descriptive study aimed to evaluate the feasibility of telemedicine guidance using a standardized multi-organ sonographic assessment protocol in untrained GPs during a COVID-19 emergency in a field hospital. METHODS Eleven COVID-19 in-patients presenting life-threatening complications, attended by local staff who spontaneously requested on-time teleconsultation, were enrolled. All untrained doctors successfully positioned the transducer and obtained key images guided by a remote doctor via telemedicine, with remote interpretation of the findings. RESULTS Only four (36%) general practitioners obtained the appropriate key heart image on the left parasternal long axis window, and three (27%) had an image interpreted remotely on-time. The evaluation time ranged from seven to 42 minutes, with a mean of 22.7 + 12. CONCLUSIONS Telemedicine is effective in guiding GPs to perform portable ultrasound in life-threatening situations, showing effectiveness in conducting decisions.
