Introduction / Innovation Concept: In Canada, family physicians (FPs) provide the majority of 1st trimester pregnancy care and are often first to evaluate complications, including threatened and spontaneous abortion and ectopic pregnancy. To receive a same day urgent US, most patients will be sent to the emergency department (ED). With increasing availability and affordability of point of care ultrasound (PoCUS), FPs are starting to use US in their offices, potentially diverting some ED visits for patients with reassuring US findings. To date, no formal certification process exists for FPs who wish to use PoCUS for 1st trimester indications. Methods: The objective of this educational initiative was to implement and evaluate a novel, 2-day didactic and hands-on certification process for FPs utilizing office-based PoCUS to identify intrauterine pregnancy and fetal cardiac activity. The FaMOUS course was modeled after the Canadian Emergency Ultrasound Society Emergency Department Echo (CEUS EDE) curriculum and adapted with permission for FPs. Curriculum, Tool, or Material: The curriculum consisted of a deliberate practice mastery model utilizing on-line materials, seminars and hands-on training. Prior to the 2-day course, FPs completed an e-learning module comprised of core competency material specific to obstetrical practice. Learners were required to score 100% on a post-module exam to participate in the 2-day course. Attendees participated in a 4-hour training session to learn US image generation and interpretation. This was followed by 10 hours of hands-on training with CEUS instructor supervision to complete the certification process (50 determinate scans). Thirteen FPs from 3 family practice units successfully completed the certification process. Cumulative knowledge and skill levels were assessed throughout the 2-day workshop through feedback from CEUS supervisors to confirm key concepts were learned. All 13 participants agreed to utilize PoCUS in their clinical assessments of patients with 1st trimester complaints using handheld PoCUS equipment provided to the sites. FPs will be surveyed at 3 month intervals for 12 months following the FaMOUS course to assess provider confidence, satisfaction and perceived impact on clinical decision-making. Conclusion: The FaMOUS certification course is a standardized curriculum by which FPs can learn PoCUS safely to improve quality and timeliness of care for patients experiencing 1st trimester complaints. If PoCUS is adopted by FPs, lengthy ED visits may be decreased for this patient population.

Point Of Care Ultrasound

Introduction: In Canada, family physicians (FPs) provide the majority of early pregnancy care. To receive a same day US, most patients will be sent to the emergency department (ED). FPs are starting to use point of care ultrasound (POCUS) for a variety of indications. The FaMOUS course was modeled after the Canadian Emergency Ultrasound Society (CEUS) ED Echo (EDE) curriculum and adapted with permission for FPs. The objective of this study was to assess the indications for POCUS use in early pregnancy and determine the diagnostic accuracy of POCUS performed by FPs following FaMOUS certification to detect intrauterine pregnancy (IUP) and fetal cardiac activity (FCA). Methods: This was a prospective, observational study conducted in 3 FP clinics from November 2015 to June 2016. Pregnant women <20 weeks gestational age who underwent a focused, transabdominal POCUS by a FaMOUS-certified FP using a handheld GE VScan were enrolled. FPs documented the presence or absence of IUP and FCA. The reference standard was radiologist-interpreted US performed after the FP POCUS. FPs were surveyed to assess provider confidence using POCUS and perceived impact on clinical decision-making. Results: Of 253 eligible patients, 56 (22.1%) underwent POCUS. Of these, 50 (89.3%) had a radiologist-interpreted US following the office-based FP visit. POCUS was used for the following indications: 11 (19.6%) had vaginal bleeding, 5 (8.9%) had abdominal pain, 7 (12.5%) had both vaginal bleeding and abdominal pain, and the indication for 33 (58.9%) patients was unclear. All patients had a documented IUP, resulting in a sensitivity of 94.0% (95% CI: 83.5%, 98.5%) and 100% positive predictive value. FCA resulted in sensitivity of 82.9% (95% CI: 69.2, 92.4%) and specificity of 100% (95% CI: 29.2%, 100.0%). When surveyed, 100% of FPs were confident performing POCUS and reported POCUS had an overall positive impact on clinical practice. 75% agreed the use of POCUS decreased the need for urgent radiologist-interpreted US. Conclusion: Following a certification process modeled after the CEUS EDE curriculum, FPs used POCUS for both CEUS-defined indications and indications that were unclear. FPs trained in early pregnancy POCUS demonstrated excellent diagnostic accuracy identifying IUP and FCA. Future study should assess the clinical impact of office-based POCUS, including whether its use results in decreased ED visits for this patient population.

ABSTRACTObjectivesPoint-of-care ultrasound (POCUS) is used increasingly during resuscitation. The aim of this study was to assess whether combining POCUS and electrocardiogram (ECG) rhythm findings better predicts outcomes during cardiopulmonary resuscitation in the emergency department (ED).MethodsWe completed a health records review on ED cardiac arrest patients who underwent POCUS. Primary outcome measurements included return of spontaneous circulation (ROSC), survival to hospital admission, and survival to hospital discharge.ResultsPOCUS was performed on 180 patients; 45 patients (25.0%; 19.2%–31.8%) demonstrated cardiac activity on initial ECG, and 21 (11.7%; 7.7%–17.2%) had cardiac activity on initial POCUS; 47 patients (26.1%; 20.2%–33.0%) achieved ROSC, 18 (10.0%; 6.3%–15.3%) survived to admission, and 3 (1.7%; 0.3%–5.0%) survived to hospital discharge. As a predictor of failure to achieve ROSC, ECG had a sensitivity of 82.7% (95% CI 75.2%–88.7%) and a specificity of 46.8% (32.1%–61.9%). Overall, POCUS had a higher sensitivity of 96.2% (91.4%–98.8%) but a similar specificity of 34.0% (20.9%–49.3%). In patients with ECG-asystole, POCUS had a sensitivity of 98.18% (93.59%–99.78%) and a specificity of 16.00% (4.54%–36.08%). In patients with pulseless electrical activity, POCUS had a sensitivity of 86.96% (66.41%–97.22%) and a specificity of 54.55% (32.21%–75.61%). Similar patterns were seen for survival to admission and discharge. Only 0.8% (0.0–4.7%) of patients with ECG-asystole and standstill on POCUS survived to hospital discharge.ConclusionThe absence of cardiac activity on POCUS, or on both ECG and POCUS together, better predicts negative outcomes in cardiac arrest than ECG alone. No test reliably predicted survival.

Introduction: Coronavirus disease 2019 (COVID-19) is caused by the virus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Several case series from Italy and China have highlighted the lung ultrasound findings of this disease process and may demonstrate its clinical utility during the current pandemic. Case Report: We present a case of a COVID-19 patient who presented to the emergency department twice within a 24-hour period with rapidly progressing illness. A multi-organ point-of-care ultrasound (POCUS) evaluation was used on the return visit and assisted clinical decision-making. Discussion: A multi-organ POCUS exam allows for quick assessment of acute dyspnea in the emergency department. As the lung involvement of COVID-19 is primarily a peripheral process it is readily identifiable via lung ultrasound. We believe that when applied efficiently and safely a POCUS exam can reduce clinical uncertainty and potentially limit the use of other imaging modalities when treating patients with COVID-19. Conclusion: This case highlights the utility of an early multiorgan point-of-care assessment for patients presenting with moderate respiratory distress during the severe SARS-CoV-2 pandemic.

BACKGROUND: Point-of-care ultrasound (POCUS) is the core competency in the Emergency Medicine (EM) residency training. However, there are many methods that can be used to evaluate this competency, and the best practices for teaching ultrasonography to residents have yet to be determined. AIM: The researchers aimed at evaluating the POCUS knowledge and skills of the EM residents after having participated in the POCUS training during their first ultrasound rotation in the Emergency Department. METHODS: A curriculum was developed in the form of a 2-week rotation in the EM residency program at the Department of EM at Khon Kaen University’s Srinagarind Hospital. It consisted of didactic lectures, bedside ultrasound trainings, the journal club, and the process of reviewing the images. Tools were developed, which included a knowledge exam. For each resident, the assessments were administered before and after the rotation. Furthermore, an ultrasound skills test was developed to be used at the end of the 1st year EM residency program. RESULTS: Nine EM residents completed their rotations and the tests. The average pre-training score and post-training scores were 5.25 ± 1.03 and 8.50 ± 1.20, respectively. The mean difference score between pre- and post-test was 3.25 ± 1.28. (95% CI −4.321, −2.178). In terms of the ultrasound skills test, the average total score was 26.13 out of 30 (87.1%). Moreover, the residents had higher scores in the aspects of image acquisition (87.5%) and image interpretation (87.5%). However, for the aspect of clinical decision-making, the average score was 75%. The survey questions indicated that with respect to all of the academic activities, the “Bedside ultrasound,” which had encouraged the residents to learn POCUS, was given the highest score (4.75 of 5). CONCLUSIONS: The 2-week ED ultrasound rotation had improved the residents’ EM ultrasound knowledge and skills.

ABSTRACTOcular complaints prompt a significant number of emergency department (ED) visits, and they can range from benign to sight-threatening. Detailed fundoscopic examination is difficult, even for experienced providers. Point-of-care ultrasound (POCUS) is increasingly utilized in the ED for numerous applications, including ocular evaluation. We present a case in which ocular POCUS was used to diagnose a submacular hemorrhage in a patient who presented with acute painless loss of vision. Ocular POCUS can be readily employed to assess for myriad clinically significant pathologies.

Point-of-care ultrasound (POCUS) is an important tool for diagnosis and management across medical specialties. This scoping review consolidates POCUS education literature, examining how curricula are developed, implemented, and assessed. We identify literature gaps, explore directions for further research, and provide recommendations for curriculum development, implementation, and improvement. MethodsWe conducted a scoping review per the framework outlined by Arksey & O’Malley. A systematic search of the MEDLINE, EMBASE, Cochrane, ERIC, Web of Science, and Scopus databases was conducted to identify published, English language literature, on POCUS education in undergraduate or graduate medical training.ResultsOf 6,164 articles identified, 421 were analyzed in depth. Curricular content included diverse diagnostic and therapeutic applications, varying significantly by specialty. Teaching modalities included in-person didactics (74%), human models (58%), simulation (33%), and web-based didactics (18%). Several studies showed better outcomes for structured vs. apprenticeship curricula, hands-on teaching vs. didactic lectures, and human models vs. simulators. Web-based didactics were as effective as in-person didactics and conveyed benefits in reusability, cost, and instructor time. Dedicated electives and boot-camps were identified as effective. Few curricula assessed knowledge retention (5%), clinical decision making (3%), learner behavior (12%), or patient outcomes (6%). ConclusionScholarly POCUS education literature is expanding. Curricular content varies and should be tailored to specialty needs. Structured curricula utilizing hands-on learning, electives, and boot-camps can enhance educational outcomes. Higher-level outcomes such as knowledge retention, clinical decision making, learner behavior, and patient outcomes, are lacking and should be a focus of further researchResumeL’échographie au point de service (POCUS) est un outil important pour le diagnostic et la gestion dans toutes les spécialités médicales. Cette étude de portée consolide la littérature éducative POCUS, en examinant comment les programmes d’enseignement sont élaborés, mis en œuvre et évalués. Nous identifions les lacunes de la littérature, explorons les directions à prendre pour des recherches plus approfondies et fournissons des recommandations pour le développement, la mise en œuvre et l’amélioration des programmes d’enseignement. MéthodesNous avons procédé à un examen de portée conformément au cadre défini par Arksey & O’Malley. Une recherche systématique dans les bases de données MEDLINE, EMBASE, Cochrane, ERIC, Web of Science et Scopus a été effectuée afin d’identifier les publications en langue anglaise sur l’enseignement POCUS dans le cadre de la formation médicale de premier ou de deuxième cycle. RésultatsSur les 6 164 articles identifiés, 421 ont fait l’objet d’une analyse approfondie. Le contenu des programmes d’études comprenait diverses applications diagnostiques et thérapeutiques, variant considérablement selon les spécialités. Les modalités d’enseignement comprenaient la didactique en personne (74 %), les modèles humains (58 %), la simulation (33 %) et la didactique basée sur le web (18 %). Plusieurs études ont montré de meilleurs résultats pour les programmes structurés par rapport aux programmes d’apprentissage, l’enseignement pratique par rapport aux cours magistraux didactiques, et les modèles humains par rapport aux simulateurs. La didactique basée sur le web était aussi efficace que la didactique en personne et présentait des avantages en termes de réutilisation, de coût et de temps de l’instructeur. Les cours optionnels et les camps d’entraînement ont été jugés efficaces. Peu de programmes ont évalué la rétention des connaissances (5 %), la prise de décision clinique (3 %), le comportement des apprenants (12 %) ou les résultats pour les patients (6 %). ConclusionLa littérature éducative POCUS est en pleine expansion. Le contenu des programmes d’études varie et doit être adapté aux besoins spécifiques. Des programmes structurés utilisant un apprentissage pratique, des cours optionnels et des camps d’entraînement peuvent améliorer les résultats scolaires. Des résultats de plus haut niveau, tels que la rétention des connaissances, la prise de décision clinique, le comportement de l’apprenant et les résultats pour le patient, font défaut et devraient faire l’objet de recherches plus approfondies.

Introduction: The use of cardiac point of care ultrasound (PoCUS) to assess cardiac arrest patients is widespread, although not mandated by advanced cardiac life support (ACLS) guidelines. This study aims to examine if the use of ultrasound, along with the findings on ultrasound are associated with a difference in outcomes of cardiac arrest patients in the emergency department (ED). Methods: A retrospective database and chart analysis was completed for patients arriving to a tertiary ED in asystole or PEA cardiac arrest, between 2010 and 2014. Patients were excluded if aged under 19, or with a previous DNR order. Patients were grouped based on whether PoCUS was used during ACLS (PoCUS group) and those without PoCUS (control group). Multiple data were abstracted from charts using a standardized form. Data was analyzed for the return of spontaneous circulation (ROSC), survival to hospital admission (SHA), and survival to hospital discharge (SHD), as well as initial cardiac activity findings on PoCUS. Results: 230 patients met the study inclusion criteria, with 44 (19%) in the control group, and 186 (81%) in the PoCUS group. In the PoCUS group 20 (11%) had cardiac activity (Positive PoCUS) and 166 (89%) had no cardiac activity recorded. The control group had a higher rate of SHA than the PoCUS group (27%; 95% CI 15-43% vs. 10%: 6-15%, p = 0.0046), however there was no difference in frequency of ROSC (control: 37%; 24-55% vs. PoCUS 26%; 20-33%, p = 0.1373) or SHD (control: 7%, 95% CI 1-19%; PoCUS: 2%, 95% CI 0-5%, p = 0.0858). Positive PoCUS patients had a higher frequency of ROSC (75%; 50-91% vs. 20%; 15-27%, p < 0.001) and SHA (25%; 9-49% vs. 8%; 4-13%, p = 0.0294) than patients with no PoCUS cardiac activity, however there was no difference in the rate of SHD between the positive PoCUS patients (0%; 0-17%) and patients with no PoCUS cardiac activity (2%; 0-5%, p = 1.0000). Conclusion: Our results suggest that there is no difference in survival between cardiac arrest patients receiving PoCUS and those who do not. Although finding positive cardiac activity on PoCUS is associated with greater ROSC and survival to hospital admission, it does not identify patients with a final outcome of survival to hospital discharge.

Introduction: The use of cardiac point of care ultrasound (PoCUS) to assess cardiac arrest patients is widespread, although not mandated by advanced cardiac life support (ACLS) guidelines. This study aims to examine if the use of ultrasound is associated with a difference in the length of resuscitation and the frequency of interventions during ACLS in the emergency department (ED). Methods: A retrospective database and chart analysis was completed for patients arriving to a tertiary ED in cardiac arrest, between 2010 and 2014. Patients were excluded if aged under 19, or with a previous DNR order. Patients were grouped based on whether PoCUS was used during ACLS (PoCUS group) and those without PoCUS (control group). Multiple data were abstracted from charts using a standardized form. Data was analyzed for the length of resuscitation, frequency of common ACLS interventions such as endotracheal intubation, administration of epinephrine, and defibrillation, as well as initial cardiac activity findings on PoCUS. Results: 263 patients met the study inclusion criteria, with 51 (19%) in the control group, and 212 (81%) in the PoCUS group. In the PoCUS group 23 (11%) had cardiac activity (Positive PoCUS) and 189 (89%) had no cardiac activity recorded. Positive PoCUS patients had longer mean resuscitation times (26.13 min, 95% CI 17.80-34.46 min) compared to patients with no PoCUS cardiac activity (12.63 min, 95% CI 11.07-14.19 min, p < 0.05) as well as to the control group (14.20 min, 95% CI 10.30-18.09 min, p < 0.05). Positive PoCUS patients were more likely to receive endotracheal intubation (91%, 95% CI 72-99%), and epinephrine (100%, 95% CI 85-100%) than patients with no PoCUS cardiac activity (ET: 47%, 95% CI 40-54%, p < 0.0001; Epi: 81%, 95% CI 75-86%, p < 0.0172) and than the control group (ET: 65%, 95% CI 50-78%, p < 0.0227; Epi: 80%, 95% CI 67-90%, p < 0.0258). There was no difference in numbers receiving defibrillation between groups. Conclusion: Our results suggest emergency physicians may be making increased resuscitative effort for patients with positive cardiac activity findings on PoCUS compared to those with negative findings or when no PoCUS was performed.

Introduction: Point-of-care ultrasound (POCUS) has become standard practice in emergency departments ranging from remote rural hospitals to well-resourced academic centres. To facilitate quality assurance, the Canadian Association of Emergency Physicians (CAEP) recommends image archiving. Due in part to poor infrastructure and lack of a national standard, however, archiving remains uncommon. Our objective was to establish a minimum standard archiving protocol for the core emergency department POCUS indications. Methods: Itemization of potential archiving standards was created through an extensive literature review. An online, three-round, modified Delphi survey was conducted with the thirteen POCUS experts on the national CAEP Emergency Ultrasound Committee tasked with representing diverse practice locations and experiences. Participants were surveyed to determine the images or clips, measurements, mode, and number of views that should comprise the minimum standard for archiving. Consensus was pre-defined as 80%. Results: All thirteen experts participated fully in the three rounds. In establishing minimum image archiving standards for emergency department POCUS, complete consensus was achieved for first trimester pregnancy, hydronephrosis, cardiac activity versus standstill, lower extremity deep venous thrombosis, and ultrasound-guided central line placement. Consensus was achieved for the majority of statements regarding abdominal aortic aneurysm, extended focused assessment with sonography in trauma, pericardial effusion, left and right ventricular function, thoracic B-line assessment, cholelithiasis and cholecystitis scans. In total, consensus was reached for 58 of 69 statements (84.1%). This included agreement on 41 of 43 statements (95.3%) describing mandatory images for archiving in the above indications. Conclusion: Our modified Delphi-derived consensus represents the first national standard archiving requirements for emergency department POCUS. Depending on the clinical context, additional images may be required beyond this minimum standard to support a diagnosis.
