RESUMO
A focused point-of-care abdominal ultrasound is an examination performed at the patient's location and interpreted within the clinical context. This review gives an overview of this examination modality. The objective is to rapidly address predefined dichotomised questions about the presence of an abdominal aortic aneurysm, gallstones, cholecystitis, hydronephrosis, urinary retention, free intraperitoneal fluid, and small bowel obstruction. FAUS is a valuable tool for emergency physicians to promptly confirm various conditions upon the patients' arrival, thus reducing the time to diagnosis and in some cases eliminating the need for other imaging.

BACKGROUND: This scoping review was conducted to provide an overview of the evidence of point-of-care lung ultrasound (LUS) in emergency medicine. By emphasizing clinical topics, time trends, study designs, and the scope of the primary outcomes, a map is provided for physicians and researchers to guide their future initiatives. RESEARCH QUESTION: Which study designs and primary outcomes are reported in published studies of LUS in emergency medicine? STUDY DESIGN AND METHODS: We performed a systematic search in the PubMed/MEDLINE, Embase, Web of Science, Scopus, and Cochrane Library databases for LUS studies published prior to May 13, 2023. Study characteristics were synthesized quantitatively. The primary outcomes in all papers were categorized into the hierarchical Fryback and Thornbury levels. RESULTS: A total of 4,076 papers were screened and, following selection and handsearching, 406 papers were included. The number of publications doubled from January 2020 to May 2023 (204 to 406 papers). The study designs were primarily observational (n = 375 [92%]), followed by randomized (n = 18 [4%]) and case series (n = 13 [3%]). The primary outcome measure concerned diagnostic accuracy in 319 papers (79%), diagnostic thinking in 32 (8%), therapeutic changes in 4 (1%), and patient outcomes in 14 (3%). No increase in the proportions of randomized controlled trials or the scope of primary outcome measures was observed with time. A freely available interactive database was created to enable readers to search for any given interest (https://public.tableau.com/app/profile/blinded/viz/LUSinEM_240216/INFO). INTERPRETATION: Observational diagnostic studies have been produced in abundance, leaving a paucity of research exploring clinical utility. Notably, research exploring whether LUS causes changes to clinical decisions is imperative prior to any further research being made into patient benefits.
RESUMO
INTRODUCTION: In many emergency departments (ED), specialised teams are activated to take care of medical emergency patients (MEP). The aim of this study was to describe the organisation of the management of adult MEPs in Danish EDs. The study examined trigger team activation criteria, training and composition of trigger teams. METHODS: This was a cross-sectional descriptive study. A questionnaire was sent to the head of department and head nurse at each Danish ED. They recruited eligible personnel to answer the questionnaire. Data were obtained between 1 October and 15 December 2021. RESULTS: We included 23 hospitals and 19 responded (82.6%). Most EDs had a trigger call for MEP (89.5%). In 70.6% of the EDs, trigger calls for MEP were activated > 300 times annually. All EDs used red triage (Danish Emergency Process Triage) as activation criteria for MEP calls. Most respondents received simulation training (82.4%). All respondents felt adequately educated to manage MEP. The MEP trigger teams varied from three to 11 members with great variation with respect to team leaders. CONCLUSION: Management of MEP varies greatly in Danish Hospitals. A systematic approach to MEP management in line with management of trauma and stroke patients may potentially serve to improve the quality of care for and outcome of this patient group, but further research is needed. FUNDING: None. TRIAL REGISTRATION: Not relevant.

Focused cardiac ultrasound (FoCUS) is a point-of-care cardiac examination performed and interpreted by the emergency physician in the clinical context. This review summarises the current knowledge of FoCUS. The objective is to answer four predefined clinical questions: Are there any signs of pericardial effusion? Are there any signs of right ventricular dilatation? Are there any signs of reduced or hyperdynamic left ventricular function? Are there any signs of abnormal inferior vena cava? FoCUS is not a replacement for echocardiography but a useful tool in detecting cardiopulmonary pathology and haemodynamic abnormalities in the emergency setting.

Background: Dyspnea caused by pleural effusion is a common reason for admission to the emergency department (ED). In such cases, thoracentesis performed in the ED may allow for swift symptom relief, diagnostics, and early patient discharge. However, the competence level of thoracentesis and training in the ED are currently unclear. This study aimed to describe the current competencies and training in thoracentesis in Danish EDs. Methods: We performed a nationwide cross-sectional study in Denmark. A questionnaire was distributed to all EDs in March 2022 including questions on competencies and thoracentesis training methods. Descriptive statistics were used. Results: In total, 21 EDs replied (response rate 100%) between March and May 2022. Overall, 50% of consultant and 77% of physicians in emergency medicine specialist training were unable to perform thoracentesis independently. Only 2 of 21 EDs (10%) had a formalized training program. In these 2 EDs, there were no requirements of maintaining these competences. Informal training was reported by 14 out 21 (66%) EDs and consisted of ad-hoc bedside procedural demonstration and/or guidance. Among the 19 EDs without formalized training, 9 (47%) had no intention of establishing a formalized training program. Conclusion: We found a major lack of thoracentesis competencies in Danish EDs among both consultant and physicians in emergency medicine specialist training. Moreover, the vast majority of EDs had no formalized thoracentesis training program.
RESUMO
Background: In this study we aimed to assess if a focused lung ultrasound examination predicts the need for mechanical ventilation, admission to an intensive care unit, high-flow oxygen treatment, death from COVID-19 within 30â days and 30-day all-cause mortality in patients with clinical suspicion of COVID-19 or PCR-verified SARS-CoV-2 infection. Methods: A multicentre prospective cohort trial was performed. Film clips from focused lung ultrasound examinations were recorded and rated by blinded observers using different scoring systems. A prediction model was built and used to test relationship between lung ultrasound scores and clinical outcomes. Diagnostic performance of scoring systems was analysed. Results: A total of 3889 film clips of 398 patients were analysed. Patients who had any of the outcomes of interest had a significantly higher ultrasound score than those who did not. Multivariable logistic regression analyses showed that lung ultrasound predicts mechanical ventilation (relative risk 2.44, 95% CI 1.32-5.52), admission to intensive care (relative risk 2.55, 95% CI 1.41-54.59) and high-flow oxygen treatment (relative risk 1.95, 95% CI 1.5-2.53) but not survival when adjusting for sex, age and relevant comorbidity. There was no diagnostic difference in area under the receiver operating characteristic curve between a scoring system using only anterolateral thorax zones and a scoring system that also included dorsal zones. Conclusion: Focused lung ultrasound in patients with clinical suspicion of COVID-19 predicts respiratory failure requiring mechanical ventilation, admission to intensive care units and the need for high-flow oxygen treatment. Thus, focused lung ultrasound may be used to risk stratify patients with COVID-19 symptoms.
RESUMO
Problem framing is critical to developing risk prediction models because all subsequent development work and evaluation takes place within the context of how a problem has been framed and explicit documentation of framing choices makes it easier to compare evaluation metrics between published studies. In this work, we introduce the basic concepts of framing, including prediction windows, observation windows, window shifts and event-triggers for a prediction that strongly affects the risk of clinician fatigue caused by false positives. Building on this, we apply four different framing structures to the same generic dataset, using a sepsis risk prediction model as an example, and evaluate how framing affects model performance and learning. Our results show that an apparently good model with strong evaluation results in both discrimination and calibration is not necessarily clinically usable. Therefore, it is important to assess the results of objective evaluations within the context of more subjective evaluations of how a model is framed.
RESUMO
Point-of-are ultrasound (PoCUS) has become an integrated part of initial diagnostics and procedural guidance after establishing emergency departments and a speciality in emergency medicine in Denmark. Focused PoCUS is a fast examination, which is done and interpreted bedside to answer clinical, predefined dichotomous questions. Emergency physicians have an obligate course in PoCUS as part of their training and must be certified to get speciality recognition. In this review we argue, that the future of PoCUS is continuing the development of the education and training in PoCUS and in further research.

BACKGROUND: The use of simulation-based team training has increased over the past decades. Simulation-based team training within emergency medicine and critical care contexts is best known for its use by trauma teams and teams involved in cardiac arrest. In the domain of emergency medicine, simulation-based team training is also used for other typical time-critical clinical presentations. We aimed to review the existing literature and current state of evidence pertaining to non-technical skills obtained via simulation-based team training in emergency medicine and critical care contexts, excluding trauma and cardiac arrest contexts. METHODS: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Before the initiation of the study, the protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database. We conducted a systematic literature search of 10 years of publications, up to December 17, 2019, in the following databases: PubMed/MEDLINE, EMBASE, Cochrane Library, and CINAHL. Two authors independently reviewed all the studies and extracted data. RESULTS: Of the 456 studies screened, 29 trials were subjected to full-text review, and 13 studies were included in the final review. None of the studies was randomized controlled trials, and no studies compared simulation training to different modalities of training. Studies were heterogeneous; they applied simulation-training concepts of different durations and intensities and used different outcome measures for non-technical skills. Two studies reached Kirkpatrick level 3. Out of the remaining 11 studies, nine reached Kirkpatrick level 2, and two reached Kirkpatrick level 1. CONCLUSIONS: The literature on simulation-based team training in emergency medicine is heterogeneous and sparse, but somewhat supports the hypothesis that simulation-based team training is beneficial to teams' knowledge and attitudes toward non-technical skills (Kirkpatrick level 2). Randomized trials are called for to clarify the effect of simulation compared to other modalities of team training. Future research should focus on the transfer of skills and investigate improvements in patient outcomes (Kirkpatrick level 4).
RESUMO
BACKGROUND: Point-of-Care ultrasound (POCUS) changes the management in specific groups of patients in the Emergency Department (ED). It seems intuitive that POCUS holds an unexploited potential on a wide variety of patients. However, little is known about the effect of ultrasound on the broad spectrum of unselected patients in the ED. This study aimed to identify the effect on the clinical management if POCUS was applied on unselected patients. Secondarily the study aimed to identify predictors of ultrasound changing management. METHODS: This study was a blinded observational single center trial. A basic whole body POCUS protocol was performed in extension to the physical examination. The blinded treating physicians were interviewed about the presumptive diagnosis and plan for the patient. Subsequently the physicians were unblinded to the POCUS results and asked to choose between five options regarding the benefit from POCUS results. RESULTS: A total of 403 patients were enrolled in this study. The treating physicians regarded POCUS examinations influence on the diagnostic workup or treatment as following: 1) No new information: 249 (61.8%), 2) No further action: 45 (11.2%), 3) Further diagnostic workup needed: 52 (12.9%), 4) Presumptive diagnosis confirmed 38 (9.4%), and 5) Immediate treatment needed: 19 (4.7%). Predictors of beneficial ultrasound were: (a) triage > 1, (b) patient comorbidities (cardiac disease, hypertension or lung disease), or (c) patients presenting with abdominal pain, dyspnea, or syncope. CONCLUSION: POCUS was found to be potentially beneficial in 27.0% of all patients. High triage score, known cardiac disease, hypertension, pulmonary diseases, a clinical presentation with abdominal pain, dyspnea, or syncope are predictors of this. Future research should focus on patient-important outcomes when applying POCUS on these patients. TRIAL REGISTRATION: The trail was registered prior to patient inclusion with the Danish Data Protection Agency (https://www.datatilsynet.dk/ Case no: 1-16-02-603-14) and Clinical Trials (www.clinicaltrials.gov/ Protocol ID: DNVK1305018).

Minor emergency departments (ED) struggle to access sufficient expertise to supervise learners of lung and cardiac point-of-care ultrasound (POCUS). Using tele-ultrasound (tele-US) for remote supervision may remedy this situation. We aimed to evaluate the feasibility of real-time supervision via tele-US when applied to an everyday ED clinic. We conducted a mixed methods study that assessed practical feasibility, determined performance, and explored users' acceptability of supervision via tele-US. Technical performance was assessed quantitatively by the ratio in mean gray value between images on site and as received by the supervisor, and by after-compression frame rate. Qualitatively, 12 exploratory semi-structured interviews were conducted with exposed junior doctors and supervisors. Remote supervision via tele-US was performed with 10 junior doctors scanning 45 included patients. During performance assessment, neither alternating internet connection nor software significantly changed the mean gray value ratio. The lowest median frame rate of 4.6 (interquartile range [IQR]: 3.1-5.0) was found by using a 4G internet connection; the highest of 28.5 (IQR: 28.5-29.0) was found with alternative computer and local area network internet connection. In interviews, supervisors stressed the importance of preserving frame rate, and junior doctors emphasized a need for shared ultrasound terminology. In the qualitative analysis, setup mobility, accessibility, and time consumption were emphasized as being of key importance for future clinical implementations. Remote supervision via a commercially available and low-cost tele-US setup is operational for both junior doctors and supervisors when applied to lung and cardiac POCUS scans of hospitalized patients.

BACKGROUND: Supervision via tele-ultrasound presents a remedy for lacking on-site supervision in focused cardiac ultrasound, but knowledge of its impact is largely absent. We aimed to investigate tele-supervised physicians' cine-loop quality compared to that of non-supervised physicians and compared to that of experts. METHODS: We conducted a single-blinded cluster randomized controlled trial in an emergency department in western Denmark. Physicians with basic ultrasound competence scanned admitted patients twice. The first scan was non-supervised, and the second was non-supervised (control) or tele-supervised (intervention). Finally, experts in focused cardiac ultrasound scanned the same patient. Two blinded observers graded cine-loops recorded from all scans on a 1-5 scale. The outcome was the mean summarized scan gradings compared with a linear mixed-effects model. RESULTS: In each group, 10 physicians scanned 44 patients. From the mean summarized gradings, on a scale from 4 to 20, the second non-supervised scan grading was 10.9 (95% CI 10.2-11.7), whereas the tele-supervised grading was 12.6 (95% CI: 11.8-13.3). From the first to the second scan, tele-supervised physicians moved 9% (1.09; 95% CI: 1.00-1.19; P = 0.041) closer to the experts' quality than the non-supervised physicians. CONCLUSION: Tele-supervised physicians performed scans of better quality than non-supervised physicians. The present study supports the use of tele-supervision for physicians with basic focused ultrasound competence in a setting where on-site supervision is unavailable.

BACKGROUND: Point-of-care ultrasound (POCUS) can improve patient management in the emergency department (ED). However, previous studies have focused only on selected groups of patients, such as trauma, shock, dyspnea, or critically ill patients, or patients with an already known diagnosis. Most patients seen in the ED do not match these criteria. We aim to present total prevalence of positive findings when basic POCUS is applied to the broad population of patients seen in an emergency department. METHODS: We conducted a single-center prospective explorative observational study of 405 unselected patients aged 18 years or over. A structured whole-body ultrasound examination was performed on all patients within 2 h of arrival to the ED. The ultrasound examination consisted of focused cardiac ultrasound, focused abdominal ultrasound, focused assessment with sonography for trauma (FAST), and focused lung ultrasound. RESULTS: We managed to perform 94.5% of all planned examinations. The study revealed positive findings in 39.3% of all included patients. This study presents the prevalence of positive findings among subgroups of patients. Divided among the categories of chief complaint, we found 62 positive examinations in 58 (14.3%; 95% CI, 10.9-17.7) unique patients with orthopedic complaints, 77 positive examinations among 59 (14.6%; 95% CI, 11.1-18.0) unique patients with medical complaints, and 55 positive examinations among 42 (10.4%; 95% CI, 7.4-13.3) unique patients with abdominal surgical complaints. CONCLUSION: POCUS revealed positive findings in more than one third of unselected patients in the emergency department. The study presents the findings and distribution among categories of chief complaints. Future investigations are necessary to elucidate the implication of the findings.

INTRODUCTION: With the increasing use of recreational trampolines, more injuries are seen in emergency depart-ments (ED). Little is known about the relationship between adherence to safety precautions and injuries. This retro-spective study aims to describe the types of injuries and the precautions taken when using trampolines, and to investigate the relationship between injuries and safety precautions. METHODS: We reviewed patient lists and the medical records of children younger than 18 years who were treated between 1 April and 30 September 2014 at the ED of Hospital Unit West, Denmark. Demographic data and type of injury were recorded. Patients or guardians were contacted for a structured telephone interview to describe the safety precautions they had taken before the injury occurred. A total of 113 patients were identified, and 100 patients were included in the phone interviews. A total of 13 patients were excluded due to incorrect/missing phone numbers or lack of a Danish home address. RESULTS: 6% of all children treated in the ED had trampoline-related injuries. A total of 58 (51.3%) patients had fracture injuries, and 55 (48.7%) patients had non-fracture injuries. 4% had complied with all five recommended safety precautions. CONCLUSIONS: This study describes types of injuries and safety precautions related to trampoline use. 6% of all children in the ED had an injury related to trampoline use. 4% complied with all five recommended safety precautions. FUNDING: none. TRIAL REGISTRATION: not relevant.

BACKGROUND: Point-of-care ultrasound (PoCUS) is spreading throughout Emergency Medicine, Critical Care and Pre-hospital Care. However, there is an underlying inherited conflict with the established specialties performing comprehensive examinations. It has been stated that PoCUS is disruptive innovation. If this is true the definition might open up for a new perspective on differentiating comprehensive ultrasound from PoCUS. PoCUS in the light of disruptive innovation is a different perspective on ultrasound that has not before been academically scrutinized. METHODS: In this paper we investigate if PoCUS is in fact disruptive innovation. This is done by comparative analysis with the point of departure in disruptive innovation theory known from the business world. RESULTS: We find that a disruptive innovation process is happening. This new knowledge allows us to put forward advice for the stakeholders in the field of ultrasound. It also allows us to challenge the conventional pyramid of expertise used to describe different types of ultrasound. The perspective of this paper is mutual understanding of similarities and differences between conventional and point-of-care ultrasound. Only with this understanding the stakeholders can collaborate and use the full spectrum of ultrasound for the benefit of the patient.
RESUMO
BACKGROUND: Trauma is a leading cause of death among adults aged < 44 years, and optimal care is a challenge. Evidence supports the centralization of trauma facilities and the use multidisciplinary trauma teams. Because knowledge is sparse on the existing distribution of trauma facilities and the organisation of trauma care in Denmark, the aim of this study was to identify all Danish facilities that care for traumatized patients and to investigate the diversity in organization of trauma management. METHODS: We conducted a systematic observational cross-sectional study. First, all hospitals in Denmark were identified via online services and clarifying phone calls to each facility. Second, all trauma care manuals on all facilities that receive traumatized patients were gathered. Third, anesthesiologists and orthopedic surgeons on call at all trauma facilities were contacted via telephone for structured interviews. RESULTS: A total of 22 facilities in Denmark were found to receive traumatized patients. All facilities used a trauma care manual and all had a multidisciplinary trauma team. The study found three different trauma team activation criteria and nine different compositions of teams who participate in trauma care. Training was heterogeneous and, beyond the major trauma centers, databases were only maintained in a few facilities. CONCLUSION: The study established an inventory of the existing Danish facilities that receive traumatized patients. The trauma team activation criteria and the trauma teams were heterogeneous in both size and composition. A national database for traumatized patients, research on nationwide trauma team activation criteria, and team composition guidelines are all called for.

Evidence-based standards in proficiency are needed for ultrasound-guided peripheral intravenous access. In this study, we explored the validity of the Peripheral Ultrasound-Guided Vascular Access (P-UGVA) Rating Scale.We recruited 3 groups of physicians (5 novices, 5 intermediates, and 5 experts) of increasing proficiency in peripheral ultrasound-guided intravenous access. All participants performed 3 peripheral ultrasound-guided intravenous accesses on three different patients. Performance was video-recorded by 3 cameras and the ultrasound image. Synchronized and anonymized split-screen film clips were rated using the P-UGVA rating scale by 2 assessors, which also assessed overall performance on a 1-5 Likert-scale. Evidence of validity was explored using the contemporary validity framework by Messick (content, response process, internal structure, relations to other variables, and consequences).Content and response process was ensured in the development of the rating scale and validity study. Internal consistency of the P-UGVA rating scale was excellent and sufficient high for certification purposes (Cronbach's alpha = 0.91). Proficiency groups were successfully discriminated by the UPGIVA rating scale (P = .029, one-way ANOVA), and the P-UGVA rating scale scores also correlated strongly with the overall performance evaluations (rhoâ=â0.87, Pâ<â.001, Pearson correlation). We calculated a pass/fail score of 29, which lead to a theoretical false positive rate of 26.5% and false negative rate of 8.5%.We present validity evidence for the P-UGVA rating scale and an evidence-based standard in proficiency for ultrasound-guided peripheral intravenous access.

BACKGROUND: The Focused Assessment with Sonography in Trauma (FAST) protocol is considered beneficial in emergent evaluation of trauma patients with blunt or penetrating injury and has become integrated into the Advanced Trauma Life Support (ATLS) protocol. No guidelines exist as to the use of ultrasonography in trauma in Denmark. We aimed to determine the current use of ultrasonography for assessing trauma patients in Denmark. METHODS: We conducted a nation-wide cross-sectional investigation of ultrasonography usage in trauma care. The first phase consisted of an Internet-based investigation of existing guidelines, and the second phase was a series of structured interviews of orthopedic surgeons, anesthesiologists, and radiologists on call in all hospitals receiving traumatized patients in Denmark. RESULTS: Guidelines were obtained from all 22 hospitals receiving traumatized patients in Denmark. Twenty-one (95.5%) of the guidelines included and recommended FAST as part of trauma assessment. The recommended person to perform the examination was the radiologist in n = 11 (50.0%), the surgeon in n = 6 (27.3%), the anesthesiologist in n = 1 (4.5%), and unspecified in n = 3 (13.6%) facilities. FAST indications varied between circulatory instability n = 8 (36.4%), team leader's discretion n = 6 (27.3%), abdominal trauma n = 3 (13.6%), and not specified n = 6 (27.3%). Telephone interviews revealed that exams were always n = 8 (36.4%) or often n = 4 (18.2%) registered in the patients' charts. The remaining n = 10 (45.5%) facilities either never registered n = 2 (9.1%), it was not possible to register n = 1 (4.5%), or unknown by the trauma leaders n = 7 (31.8%). Images were often stored in n = 1 (4.5%), never stored in n = 10 (45.5%), not possible to store in n = 2 (9.1%), and unknown in n = 9 (40.9%) facilities. CONCLUSION: Ultrasonography was used in a non-uniform fashion by multiple specialties in Danish trauma facilities. Very few images from FAST examinations were stored and documentation was scanty. National guidelines on application and documentation of ultrasonography in trauma are called for.
RESUMO
INTRODUCTION: Peripheral vascular access is vital for treatment and diagnostics of hospitalized patients. Ultrasound-guided vascular access (UGVA) is superior to the landmark technique. To ensure competence-based education, an assessment tool of UGVA competence is needed. We aimed to develop a global rating scale (RS) for assessment of UGVA competence based on opinions on the content from ultrasound experts in a modified Delphi consensus study. METHODS: We included experts from anesthesiology, emergency medicine and radiology across university hospitals in Denmark. Nine elements were drafted based on existing literature and recommendations from international societies. In a multi-round survey, the experts rated the elements on a five-point Likert scale according to importance, and suggested missing elements. The final Delphi round occurred when >80% of the experts rated all elements ≥4 on the Likert scale. RESULTS: Sixteen experts consented to participate in the study, one withdrew consent prior to the first Delphi round, and 14 completed all three Delphi rounds. In the first Delphi round the experts excluded one element from the scale and changed the content of two elements. In the second Delphi round, the experts excluded one element from the scale. In the third Delphi round, consensus was obtained on the eight elements: preparation of utensils, ergonomics, preparation of the ultrasound device, identification of blood vessels, anatomy, hygiene, coordination of the needle, and completion of the procedure. CONCLUSIONS: We developed an RS for assessment of UGVA competence based on opinions of ultrasound experts through a modified Delphi consensus study.

Focused emergency ultrasound is rapidly evolving as a clinical skill for bedside examination by physicians at all levels of education. Ultrasound is highly operator-dependent and relevant training is essential to ensure appropriate use. When supplementing hands-on focused ultrasound courses, e-learning can increase the learning effect. We developed an emergency ultrasound app to enable onsite e-learning for trainees. In this paper, we share our experiences in the development of this app and present the final product.
