Pilot Point-of-Care Ultrasound Curriculum at Harvard Medical School: Early Experience
Introduction: Point-of-care ultrasound (POCUS) is expanding across all medical specialties. As the benefits of US technology are becoming apparent, efforts to integrate US into pre-clinical medical education are growing. Our objective was to describe our process of integrating POCUS as an educational tool into the medical school curriculum and how such efforts are perceived by students. Methods: This was a pilot study to introduce ultrasonography into the Harvard Medical School curriculum to first- and second-year medical students. Didactic and hands-on sessions were introduced to first-year students during gross anatomy and to second-year students in the physical exam course. Student-perceived attitudes, understanding, and knowledge of US, and its applications to learning the physical exam, were measured by a post-assessment survey. Results: All first-year anatomy students (n=176) participated in small group hands-on US sessions. In the second-year physical diagnosis course, 38 students participated in four sessions. All students (91%) agreed or strongly agreed that additional US teaching should be incorporated throughout the four-year medical school curriculum. Conclusion: POCUS can effectively be integrated into the existing medical school curriculum by using didactic and small group hands-on sessions. Medical students perceived US training as valuable in understanding human anatomy and in learning physical exam skills. This innovative program demonstrates US as an additional learning modality. Future goals include expanding on this work to incorporate US education into all four years of medical school

Using Lung Point-of-care Ultrasound in Suspected COVID-19: Case Series and Proposed Triage Algorithm
Introduction: First detected in December 2019, the severe acute respiratory syndrome coronavirus 2 pandemic upended the global community in a few short months. Diagnostic testing is currently limited in availability, accuracy, and efficiency. Imaging modalities such as chest radiograph (CXR), computed tomography, and lung ultrasound each demonstrate characteristic findings of coronavirus disease 2019 (COVID-19). Lung ultrasound offers benefits over other imaging modalities including portability, cost, reduced exposure of healthcare workers as well as decreased contamination of equipment such as computed tomography scanners.Case Series: Here we present a case series describing consistent lung ultrasound findings in patients with confirmed COVID-19 despite variable clinical presentations and CXR findings. We discuss a triage algorithm for clinical applicability and utility of lung point-of-care ultrasound in the setting of COVID-19 and advocate for judicious and targeted use of this tool.Conclusion: Lung point-of-care ultrasound can provide valuable data supporting diagnostic and triage decisions surrounding suspected cases of COVID-19. Prospective studies validating our proposed triage algorithm are warranted

Dyspnea in an Otherwise Healthy 18-year-old: The Importance of Point-of-care Ultrasonography
A healthy 18-year-old male presented to the emergency department with chest pain, palpitations, and dyspnea. His exam was unremarkable; however, point-of-care ultrasound (POCUS) revealed right ventricular strain with a D-sign and enlarged right ventricle. He subsequently reported a history of factor V Leiden. His D-dimer was markedly elevated, and a computed tomography angiogram of the chest demonstrated submassive pulmonary embolism (PE). He was taken to the catheterization lab for directed thrombolysis and was discharged in good condition two days later. Factor V Leiden is the most common genetic cause of venous thromboembolism. POCUS can facilitate rapid diagnosis and risk stratification of patients with acute PE
Focused Assessment with Sonography in Trauma and Abdominal Computed Tomography Utilization in Adult Trauma Patients: Trends over the Last Decade
Objective. We sought to describe the trend in abdominal CT use in adult trauma patients after a point-of-care emergency ultrasound program was introduced. We hypothesized that abdominal CT use would decrease as FAST use increased. Methods. We performed a retrospective study of 19940 consecutive trauma patients over the age of 18 admitted to our level one trauma center from 2002 through 2011. Data was collected retrospectively and recorded in a trauma registry. We plotted the rate of FAST and abdominal CT utilization over time. Head CT was used as a surrogate for overall CT utilization rates during the study period. Results. Use of FAST increased by an average of 2.3% (95% CI 2.1 to 2.5, P<0.01) while abdominal CT use decreased by the same rate annually. The percentage of patients who received FAST as the sole imaging modality for the abdomen rose from 2.0% to 21.9% while those who only received an abdominal CT dropped from 21.7% to 2.3%. Conclusions. Abdominal CT use in our cohort declined while FAST utilization grew in the last decade. The rising use of FAST may have played a role in the reduction of abdominal CT performed as decline in CT utilization appears contrary to overall trends
SonoGames: an innovative approach to emergency medicine resident ultrasound education
SonoGames was created by the Academy of Emergency Ultrasound for the 2012 annual meeting of the Society for Academic Emergency Medicine. The assessment of resident knowledge and of the performance of point-of-care ultrasound examinations is an integral component of ultrasound education and is required in emergency medicine residency training. With that in mind, game organizers sought to assess and improve emergency medicine residents’ point-of-care ultrasound knowledge, hands-on skills, and integration of knowledge into clinical decision making. SonoGames is an annual 4-hour competition consisting of 3 rounds. In this article, we provide a description of SonoGames and provide a blueprint for an effective and successful educational event

Nitrous oxide inhalant abuse and massive pulmonary embolism in COVID-19
A patient presented to the emergency department with altered mental status and lower extremity weakness in the setting of nitrous oxide inhalant abuse and Coronavirus Disease-2019 (COVID-19) infection. He subsequently developed hypotension and severe hypoxia, found to have a saddle pulmonary embolus (PE) with right heart strain requiring alteplase (tPA)
Interdisciplinary approach to enhance trauma residents education of Extended-Focused Assessment for Sonography in Trauma in the emergency department
© 2020 Royal Australasian College of Surgeons Background: Despite the utilization of point-of-care ultrasound (POCUS) by trauma surgeons, formal POCUS requirements do not exist for general surgery residents. We sought to evaluate surgery resident comfort with performing and interpreting of Extended-Focused Assessment for Sonography in Trauma (E-FAST) scans after a brief educational session. Methods: A pre-survey, sent to PGY-2 and -3 surgical residents before their trauma rotation, evaluated comfort with eight components of the E-FAST. Residents were then required to watch a 15-min online video and attend a 1-h bedside training session moderated by emergency medicine ultrasound fellows during which residents practised E-FAST image acquisition and interpretation. After the rotation, residents completed a post-survey evaluating their comfort with the E-FAST. Results: All 27 residents rotating on the trauma service during the 2017–2018 academic year were eligible and, therefore, approached by the study team. Twenty-one (77.78%) residents completed the pre-survey, training and post-survey. Initially, only 52% (13/25) of residents reported feeling confident in performing the E-FAST. After the session, all (100%) reported feeling confident in their training in E-FAST. Self-reported mean comfort with each of the eight components of the E-FAST showed a statistically significant (P \u3c 0.01) increase from pre–post survey for all residents. Isolating only the residents who initially reported feeling confident in E-FAST still showed a statistically significant (P \u3c 0.01) increase in mean comfort. Conclusion: A single POCUS training programme has been shown to improve surgical residents\u27 comfort in performing and interpreting the E-FAST. This interdisciplinary approach can enhance collaboration and bridge gaps between emergency medicine and surgery residency programmes
