Abstract
INTRODUCTION Assessment of left ventricular ejection fraction (LVEF) is one of the primary objectives of echocardiography. The gold standard assessment technique in emergency medicine is eyeballing. A new tool is now available on pocket ultrasound devices (PUD): automatic LVEF. The primary aim of this study was to evaluate the concordance between LVEF values estimated by automatic LVEF with PUD and by cardiac magnetic resonance imaging (MRI). MATERIALS This was a prospective, monocentric, and observational study. All adult patients with an indication for cardiac MRI underwent a point-of-care ultrasound. Blinded to the MRI results, the emergency physician assessed LVEF using the automatic PUD tool and by visual evaluation. RESULTS Sixty patients were included and analyzed. Visual estimation of LVEF was feasible for all patients and automatic evaluation for 52 (87%) patients. Lin's concordance correlation coefficient between automatic ejection fraction with PUD and by cardiac MRI was 0.23 (95% CI, 0.03-0.40). CONCLUSION Concordance between LVEF estimated by the automatic ejection fraction with PUD and LVEF estimated by MRI was non-existent.

Abstract
CONTEXT Point-of-Care Ultrasound (POCUS) has become an important tool in the clinical practice of many specialties, but its use and impact in General Practice in France remains to be explored. OBJECTIVE The objective of this study is to obtain a consensus among experienced French general practitioners on a list of relevant POCUS skills in General Practice in 4 anatomical regions. METHOD We used a two-round Delphi method to obtain a consensus. An initial list of skills was drawn by conducting a literature review. To rate each skill, we used a nine-point Likert scale. An interactive meeting between experts took place between Delphi rounds. POCUS experts in General Practice were defined as general practitioners with theoretical training in ultrasound who regularly perform ultrasound, who have performed ultrasound for more than five years and/or are involved in providing ultrasound training. RESULTS 11 French general practitioners screened 83 skills in 4 anatomical regions: abdominal, urogenital, vascular, gynecology and obstetrics. An agreement was obtained for 36 POCUS skills as to their appropriateness in General Practice. There were 17 skills with a strong appropriate agreement (100% of "7-9" ratings) and 19 skills with a relative agreement (100% of "5-9" ratings). CONCLUSION These skills could serve as a basis for guidelines on the use and curriculum of POCUS in General Practice in France as well as in other countries with similar healthcare systems.

Abstract
ABSTRACT Point-of-care ultrasound (POCUS) curriculum varies among countries. However, the length of training required for physicians is still under debate. We investigated the impact of different training methods: short hands-on courses (STS), long academic training sessions (LTS), or both (mixed training [MTS]), for POCUS daily use and self-reported confidence overall and specific to specific clinical situations. This was a descriptive study conducted over a 3-month period through a Web-based survey designed to assess the influence of different methods of POCUS training among physicians and residents on their daily practice. The survey was sent to 1212 emergency physicians with prior POCUS training; 515 answers (42%) could be analyzed. Participants in the STS group performed POCUS less frequently than physicians in the LTS or MTS group. Daily use in the STS group was 51% versus 82% in the LTS group and 83% in the MTS group ( P < 0.01). The overall self-reported confidence in POCUS was lower in the STS group ( P < 0.01) in all studied clinical situations. There was no significant difference between LTS and MTS groups ( P > 0.05). Method of POCUS training significantly influenced POCUS daily use. Physicians who underwent long training sessions used POCUS more frequently in their routine practice and were significantly more confident in their ability to perform and interpret a POCUS examination.

Is gallbladder PoCUS diagnostic accuracy accessible to medical students after PoCUS training exclusively on healthy volunteers? A pilot randomized control trial. Ultrasound J 2023; 15:18. [PMID: 37036612 PMCID: PMC10086079 DOI: 10.1186/s13089-023-00317-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 03/22/2023] [Indexed: 04/11/2023] Open
Abstract
BACKGROUND Point-of-care ultrasound (PoCUS) is increasingly used in clinical practice and is now included in many undergraduate curricula. Here, we aimed to determine whether medical students who participated in a PoCUS teaching program with several practical training sessions involving healthy volunteers could achieve a good level of diagnostic accuracy in identifying gallbladder pathologies. The intervention group (IG) was trained exclusively on volunteers with a healthy gallbladder, whereas the control group (CG) had access to volunteers with a pathological gallbladder as recommended in most PoCUS curricula. MATERIALS AND METHODS Twenty medical students were randomly assigned to the IG and CG. After completing the training program over 2 months, students were evaluated by three independent examiners. Students and examiners were blind to group allocation and study outcome. Sensitivity and specificity of students' PoCUS gallstone diagnosis were assessed. Secondary outcomes were students' confidence, image quality, acquisition time, and PoCUS skills. RESULTS Sensitivity and specificity for gallstone diagnosis were, respectively, 0.85 and 0.97 in the IG and 0.80 and 0.83 in the CG. Areas under the curve (AUC) based on the receiver operating characteristic curve analysis were 0.91 and 0.82 in the IG and CG, respectively, with no significant difference (p = 0.271) and an AUC difference of -0.092. No significant between-group difference was found for the secondary outcomes. CONCLUSIONS Our pilot study showed that medical students can develop PoCUS diagnostic accuracy after training on healthy volunteers. If these findings are confirmed in a larger sample, this could favor the delivery of large practical teaching sessions without the need to include patients with pathology, thus facilitating PoCUS training for students.

Abstract
INTRODUCTION Clinical ultrasonography (US) by infectiologists has only recently been developing, and as now there is little literature on the subject. Our study focuses on the conditions and diagnostic performance of clinical ultrasound imaging by infectiologists in cases of hip and knee prosthetic and native joint infection. METHODS A retrospective study carried out between June 1st 2019 and March 31st 2021 in the University Hospital of Bordeaux, South-Western France. We measured US sensitivity (Se), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV), combined or not with the analysis of articular fluid, compared to the MusculoSketetal Infection Society (MSIS) score in prosthetic joints, or to expert diagnosis in native joints. RESULTS Fifty-four patients underwent US by an infectiologist in an infectious disease ward, including 11 (20.4%) for native joint and 43 (79.6%) for prosthetic joint. Joint effusion and/or periarticular collection were highlighted in 47 (87%) patients, and US led to 44 punctures. In all patients (n=54), Se, Sp, PPV and NPV of US alone were 91%, 19%, 64% and 57%, respectively. When US was combined with fluid analysis, Se, Sp, PPV, NPV were 68%, 100%, 100%, 64% in all patients (n=54), 86%, 100%, 100%, 60% in acute arthritis (n=17) and 50%, 100%, 100% and 65% respectively in non-acute arthritis (n=37). CONCLUSION These results suggest that US by infectiologists effectively diagnoses osteoarticular infections (OAIs). This approach has many applications in infectiology routines. Consequently, it would be interesting to define the contents of a first level of infectiologist competence in US clinical practice.

Abstract
Objectif : Déterminer si la réalisation d’une échographie clinique en médecine d’urgence (ECMU) modifie la prise en charge des patients présentant une douleur abdominale aiguë d’origine non traumatique.
Matériel et méthodes : Étude rétrospective, monocentrique, incluant les patients qui ont consulté aux urgences pour douleur abdominale aiguë d’origine non traumatique entre le 1er juin 2019 et le 31 octobre 2019. Les données recueillies étaient le nombre d’examens complémentaires d’imagerie réalisés, le temps de prise en charge, le taux d’hospitalisation, le diagnostic et le taux de reconsultation à 30 jours. Le critère de jugement principal était le recours aux examens complémentaires d’imagerie spécialisée (parmi lesquels : échographie spécialisée, tomodensitométrie abdominopelvienne et abdomen sans préparation) chez les patients ayant bénéficié d’une échographie clinique (groupe « ECMU ») comparativement aux patients n’ayant pas bénéficié d’échographie (groupe « sans ECMU »).
Résultats : Mille cinquante-trois patients ont été inclus. Parmi ces patients, 16 % ont bénéficié d’une échographie clinique par le médecin urgentiste. Il existait une réduction significative du recours à l’échographie spécialisée dans le groupe ECMU (4 % dans le groupe « avec ECMU » versus 9 % dans le groupe « sans ECMU », OR = 0,45, IC 95 % : [0,17–1,00], p = 0,04), sans différence significative entre les deux groupes concernant le temps de prise en charge, l’orientation, le taux de reconsultation à 30 jours et la concordance diagnostique.
Conclusion : La réalisation d’une ECMU dans l’exploration des douleurs abdominales aiguës d’origine non traumatique entraînait une réduction significative du nombre d’échographies spécialisées, sans pour autant diminuer le temps de prise en charge ni la concordance entre le diagnostic posé aux urgences et celui en fin d’hospitalisation.

Abstract
INTRODUCTION Ultrasound imaging has many clinical applications, but there is a lack of data about its use by infectiologists. The aim of this study was to describe ultrasound performed routinely by infectiologists and to assess the diagnostic performance of ultrasound with aspirate and fluid analysis in prosthetic joint infections. METHODS Retrospective study between 1st June 2019 and 1st June 2020 in an infectious and tropical diseases unit in a tertiary University Hospital. RESULTS One hundred and thirty-one ultrasounds were performed on 127 patients by the infectious diseases team. These included 64 musculoskeletal ultrasounds (31 in native joints and 33 in prosthetic joints including 15 knees, 13 hips and 5 spacers) and 33 led to a fluid aspirate. Fourteen lung ultrasounds were done, 11 confirmed pneumopathy and 7 resulted in pleural puncture. Twenty-three vascular ultrasounds were done, 17 to insert a catheter, and four to perform a blood test. Five ultrasounds explored adenopathy, of which one node tuberculosis and one Bartonella infection were diagnosed. In prosthetic joint infections, sensitivity and specificity of ultrasound with fluid aspirate and analysis were respectively 100% and 100% for the knee and 40% and 100% for the hip. CONCLUSION Ultrasound performed by infectiologists is useful and contributes to a faster diagnosis. Furthermore, the specificity of ultrasound with aspirate and fluid analysis is very high in prosthetic joint infection. Ultrasound training courses should be considered for infectiologists including residents.

Abstract
AIMS To evaluate the implementation of the European Society of Cardiology (ESC) guidelines concerning the diagnostic management of deep vein thrombosis (DVT) in emergency departments (ED); and to estimate the additional financial cost and the increase in the time spent in the ED if the guidelines are not followed. PATIENTS AND METHODS Retrospective, bi-centric study including all patients directly admitted or referred to the ED for a suspected isolated DVT, between April 1, 2019, and July 30, 2019. The diagnostic management was compared to the 2017 ESC's guidelines. RESULTS 107 patients were included, 13 had DVT (12%) and three had superficial venous thrombosis (3%). A total of 26 patients (24%) had a diagnostic management according to guidelines. In 72 patients (67%), no assessment of clinical probability score was found. Among the 35 patients in whom a clinical probability score was calculated, 5 patients had an unnecessary D-dimer assay and 2 patients had unjustified imaging. The median time spent in the ED was 185minutes when the recommendations were followed, and 250minutes when they were not (P=0.317). The total estimated additional cost was €232.20. CONCLUSION The rate of adherence to the guidelines is low, mainly due to the absence of calculation of a clinical probability. This leads, in addition to the risk of diagnostic error, to an increase in the time spent in the EDs and inappropriate use of the technical platform, resulting in additional costs of care.

Abstract
Introduction : L’identification du profil hémodynamique des patients septiques au service d’urgence (SU) pourrait permettre d’adapter individuellement les recommandations de la Surviving Sepsis Campaign (SSC). L’objectif de cette étude était de décrire le profil hémodynamique précoce par échocardiographie ciblée chez les patients en sepsis et leur impact thérapeutique.
Méthode : Étude prospective monocentrique incluant les patients septiques (score qSOFA [quick Sepsis-related Organ Failure Assessment] ≥ 2) sur une période de 30 mois. L’échocardiographie était réalisée par des médecins urgentistes de niveau échographie clinique en médecine d’urgence 1 afin de déterminer le profil hémodynamique (hypovolémie, vasoplégie avec hyperkinésie, insuffisance ventriculaire ou profil « normal ») dès le sepsis identifié au SU. L’impact thérapeutique était défini par le nombre de patients pour lesquels l’échocardiographie modifiait le traitement de la SSC.
Résultats : Quatre-vingt-un patients (44 sepsis, 37 chocs septiques) ont été étudiés (âge moyen : 70 ± 15 ans ; hommes [n = 47, 58 %] ; SOFA = 5,3 ± 2,9 ; lactates = 4,6 ± 4,2 mmol/l ; admission en réanimation [n = 30, 37 %] ; mortalité j28 [n = 28, 35 %]) après un remplissage vasculaire médian de 500 ml (écart interquartile : 250–1 500 ml). Les profils hémodynamiques dominants étaient l’hypovolémie (n = 54, 66 %), parfois associée à une vasoplégie (n = 26, 32 %) et l’insuffisance ventriculaire (n = 21, 26 %). L’impact thérapeutique concernait 21 patients (26 %), dont un arrêt précoce du remplissage vasculaire après un volume de 850 ± 740 ml chez huit patients.
Conclusion : La dysfonction ventriculaire précoce est présente chez plus de 20 % des patients septiques. L’impact pronostique d’une évaluation échocardiographique dès l’identification du sepsis au SU reste à déterminer.

Abstract
Abstract
Introduction
Ultrasound is now recognized as a key tool in the practice of medicine in isolated situations. This study aims to evaluate the impact of transthoracic echocardiography (TTE) in a military mission when performed by a trained military practitioner (MP).
Materials and Methods
We conducted a 2-month retrospective observational study on the use of TTE in a French medical complex in Mali with a mission that included providing a medical aid to the population. All patients were included. Every ultrasound performed by the MP was listed, and the epidemiologic data, indication for the exam and results were collected for each TTE.
Results
A total of 349 patients were included, 16 were war-wounded patients and 333 came for a general medical consultation. In all, 153 ultrasounds were performed, including 48 TTEs. Sixteen TTEs were performed to evaluate injuries in war-wounded patients. During the 333 medical consultations, 32 TTEs were realized. The indications were dyspnoea (10), heart murmur (7), acute chest pain (5) and assessment of heart disease (10). TTE permitted a direct positive diagnosis for 18 patients: 7 with acute heart failure and 11 with morphologic problems. The normality of the exam was a supplementary argument to exclude a cardiac implication for eight patients.
Conclusions
TTE can provide important information with a direct impact on the management of patients. Faced with cardiac emergencies, an adapted training can be proposed for the MP. Thereby, the transfer of conventional cardiac views could facilitate the advice of a cardiologist.

Abstract
BACKGROUND Venous limited compression ultrasonography (VLCU) is recommended in case of suspicion of deep venous thrombosis (DVT). Current training pathways are rather long and include experiential phase. This aim of this study was to investigate the efficacy of a short training session for VLCU without experiential phase. The training session was applied in residents without previous ultrasound skills. Program included operation of ultrasound device and interpretation of venous images. Included patients were older than 18 years and had a suspicion of DVT. After realization of VLCU using usual technique, residents reported the dynamic compressibility of the femoral and popliteal veins, the presence or not of a visible thrombus, self-reported difficulty and duration. Patients then underwent a whole leg ultrasonography (WLCU) in the local laboratory which was blinded to VLCU results. The main criterion was the negative-predictive value (NPV) of VLCU for the absence of proximal DVT diagnosed with WLCU. Secondary criteria were VLCU diagnostic performances, rate of inability to conclude, difficulty and duration. For a NPV of 95 ± 6%, the needed number of patients was 96. This study was approved by the ethical committee. RESULTS 102 patients were analyzed. 46 residents were trained. A DVT was diagnosed by WLCU in 18 patients (prevalence of 17.6% [95% CI 11-26%]). VLCU detected 15 DVT (NPV of 96% [95% CI 89-99%]). The positive likelihood ratio was 9.9, the negative likelihood ratio 0.19 and Cohen's Kappa 0.62 [95% CI 0.52-0.71]. The sensitivity was 83% [CI 95% 60-94%] and specificity 88% [CI 95% 79-93%]. The mean number of VLCU by residents was 2.3 ± 2.1, median 2 (minimum 1, maximum 8). Mean duration was 3.4 min, difficulty was 3.7 ± 2. CONCLUSION The principal objective, NPV 96% [95% CI 89-99%], was achieved. However, this short training session was inadequate to allow ruling-out a DVT with sufficient security. Thus, the experiential phase seems to be essential.

Abstract
L’échographie clinique en médecine d’urgence (ECMU) devient une pratique intégrée à l’exercice de la spécialité. Quatre étapes semblent nécessaires au déploiement de cet outil : l’existence de preuves scientifiques sur sa pertinence clinique, l’implantation d’échographes dans les structures d’urgences (SU), la formation des médecins et l’objectivation d’un impact secondaire à son utilisation. Les preuves sur la pertinence diagnostique des techniques utilisées datent des années 1990 pour la majorité des applications utilisées aujourd’hui. La disponibilité d’un échographe adapté est également nécessaire. Si la majorité des SU disposent aujourd’hui d’un échographe, selon les recommandations françaises, toutes le devraient. Des échographes de mieux en mieux adaptés à la pratique de l’ECMU arrivent sur le marché. L’objectif doit être de permettre des examens rapides et fiables. Pour cela, une ergonomie épurée et l’implication de techniques d’intelligence artificielle semblent être l’avenir. Les médecins doivent également être formés. En France, l’utilisation de l’ECMU va se généraliser grâce à la formation de tous les nouveaux internes de médecine d’urgence. Cependant, beaucoup d’urgentistes exerçant actuellement doivent encore être formés. Pour répondre à cette demande, de nombreuses formations sont aujourd’hui accessibles. Enfin, peu de données sur l’impact clinique secondaire à l’utilisation de cet outil dans les SU sont disponibles. Après avoir défini l’ECMU, l’objectif de ce texte est d’expliquer la place de l’échographie clinique dans la spécialité de médecine d’urgence. Des perspectives d’évolution de l’ECMU sont également proposées.

Abstract
BACKGROUND Focus cardiac ultrasound is a great tool for quick evaluation of cardiac function in acute settings with limited time and expertise in echocardiography. Adequate training is essential for physicians willing to use this imaging technique. AIM The goal of this study was to assess the efficacy of a self-training programme using a cardiac ultrasound simulator. METHODS Thirty-five trainees in cardiology, emergency medicine or anaesthesiology entered the programme, which started with an e-learning lecture on focus cardiac ultrasound, with practice on a simulator, followed by implementation on patients, and ended with self-training in image analysis on an online platform. A post-test evaluation was carried out at the end of the theoretical training, followed by a final live evaluation on patients (timed acquisition of the five reference views used in focus cardiac ultrasound, grading each view on a scale of 1 to 5). Trainees were also evaluated online regarding their interpretation of 20 video clips. RESULTS The median (interquartile range) interpretability scores following simulator training were 5 (4-5) for the parasternal long-axis view, 5 (4-5) for the apical four-chamber view, and 4 (4-5) for the subcostal window. Interpretability was significantly inferior in the live evaluation compared with the post-test evaluation, except for the parasternal long-axis and subcostal views. The mean score for the video clips (out of 20) was 14.5±2.4. CONCLUSIONS After a short self-training programme, trainees were able to acquire the main views of focus cardiac ultrasound with sufficient quality and in a short time period.

Abstract
INTRODUCTION To evaluate the usefulness of point-of-care ultrasound (POCUS) performed by young military medicine residents after short training in the diagnosis of medical emergencies. METHODS A prospective study was performed in the emergency department of a French army teaching hospital. Two young military medicine residents received ultrasound training focused on gall bladder, kidneys and lower limb veins. After clinical examination, they assigned a 'clinical diagnostic probability' (CP) on a visual analogue scale from 0 (definitely not diagnosis) to 10 (definitive diagnosis). The same student performed ultrasound examination and assigned an 'ultrasound diagnostic probability' (UP) in the same way. The absolute difference between CP and UP was calculated. This result corresponded to the Ultrasound Diagnostic Index (UDI), which was positive if UP was closer to the final diagnosis than CP (POCUS improved the diagnostic accuracy), and negative conversely (POCUS decreased the diagnostic accuracy). RESULTS Forty-eight patients were included and 48 ultrasound examinations were performed. The present pathologies were found in 14 patients (29%). The mean UDI value was +3 (0-5). UDI was positive in 35 exams (73%), zero in 12 exams (25%) and negative in only one exam (2%). CONCLUSION POCUS performed after clinical examination increases the diagnostic accuracy of young military medicine residents.

Abstract
Objectif : L’échographie clinique en médecine d’urgence (ECMU) est un outil essentiel de notre pratique. L’objectif principal de notre étude était d’évaluer les caractéristiques des médecins pratiquant l’ECMU au sein de notre territoire. L’objectif secondaire était d’analyser les facteurs influençant une pratique régulière.
Matériel et méthodes : Étude descriptive multicentrique et déclarative, réalisée auprès de médecins urgentistes travaillant au sein d’un réseau territorial de médecine d’urgence à l’aide d’un questionnaire en ligne.
Résultats : Cent onze questionnaires sur 120 envoyés ont été renseignés (92 %). Onze services (92 %) étaient dotés en échographe dont neuf (82 %) en dotation propre. Soixantesix médecins (59 %) déclaraient pratiquer l’échographie régulièrement. La FAST (focused assessment with sonography for traumas) était la plus pratiquée (80 médecins, 72 %), suivie de l’exploration hémodynamique (50 médecins, 45 %) et pleurale (44 médecins, 40 %). Dans le groupe des médecins ne pratiquant pas l’ECMU, 17 médecins sur 22 (77 %) l’expliquaient par un manque de formation. Dans le même temps, l’intérêt porté à l’ECMU par les urgentistes était coté à 7 ± 2 sur une échelle de 0 à 9. Les facteurs associés à la fréquence de la pratique de l’ECMU étaient le sexe (p < 0,001), le type d’activité (p = 0,005), le type de formation à l’échographie (p < 0,001) et l’ancienneté d’équipement de son service en échographe (p < 0,001).
Conclusion : Cette enquête a montré que la pratique régulière était majoritaire avec un intérêt porté par les praticiens à l’ECMU élevé. Cependant, le frein principal à son développement était un niveau de formation jugé insuffisant par certains praticiens.

Abstract
La médecine militaire s’adapte aux dernières évolutions médicales, et l’échographie s’inscrit désormais dans les algorithmes de prise en charge des blessés de guerre. Grâce à la plus-value apportée à la clinique dans l’évaluation des blessés associée à l’amélioration des performances et à la miniaturisation des appareils, le positionnement de l’échographie en médecine de guerre a évolué pour trouver sa place « à l’avant », parfois dans des conditions sanitaires très dégradées. Après avoir rappelé les principes du secourisme au combat pour le blessé de guerre dyspnéique, cet article replace l’intérêt diagnostique et thérapeutique de l’échographie dans la « médecine de l’avant » en détaillant la sémiologie échographique des principales pathologies du blessé de guerre dans la phase de réanimation préhospitalière. L’article souligne aussi l’importance opérationnelle qu’occupe l’échographie, que ce soit sur le terrain lors des évacuations sanitaires ou lors d’afflux massif de victimes. Certains aspects de la doctrine militaire d’emploi pourraient s’adapter à la pratique en préhospitalier ou lors des situations d’exception en métropole.

Abstract
La Société française de médecine d’urgence a élaboré en 2016 des recommandations formalisées d’experts définissant le premier niveau de compétence en échographie clinique en médecine d’urgence. Ce niveau est maintenant complété par un deuxième niveau correspondant à une pratique plus avancée utilisant des techniques non envisagées dans le premier niveau comme l’utilisation du Doppler et nécessitant aussi une pratique et une formation plus poussées. Des champs déjà présents dans le premier référentiel sont complétés, et de nouveaux champs sont envisagés. La méthodologie utilisée est issue de la méthode « Recommandations par consensus formalisé » publiée par la Haute Autorité de santé et de la méthode Delphi pour quantifier l’accord professionnel. Ce choix a été fait devant l’insuffisance de littérature de fort niveau de preuve dans certaines thématiques et de l’existence de controverses. Ce document présente les items jugés appropriés et inappropriés par les cotateurs. Ces recommandations définissent un deuxième niveau de compétence en ECMU.

Abstract
BACKGROUND Ultrasound (US) has been a regular practice in emergency departments for several decades. Thus, train our students to US is of prime interest. Because US image acquisition ability can be very different from a patient to another (depending on image quality), it seems relevant to adapt US learning curves (LCs) to patient image quality using tools based on cumulative summation (CUSUM) as the risk-adjusted LC CUSUM (RLC). OBJECTIVES The aim of this study was to monitor LC of medical students for the acquisition of abdominal emergency US views and to adapt these curves to patient image quality using RLC. METHODS We asked medical students to perform abdominal US examinations with the acquisition of 11 views of interest on emergency patients after a learning session. Emergency physicians reviewed the student examinations for validation. LCs were plotted and the student was said proficient for a specific view if his LC reached a predetermined limit fixed by simulation. RESULTS Seven students with no previous experience in US were enrolled. They performed 19 to 50 examinations of 11 views each. They achieve proficiency for a median of 9 (6-10) views. Aorta and right pleura views were validated by seven students; inferior vena cava, right kidney, and bladder by six; gallbladder and left kidney by five; portal veins and portal hilum by four; and subxyphoid and left pleura by three. The number of US examinations required to reach proficiency ranged from five to 41 depending on the student and on the type of view. LC showed that students reached proficiency with different learning speeds. CONCLUSIONS This study suggests that, when monitoring LCs for abdominal emergency US, there is some heterogeneity in the learning process depending on the student skills and the type of view. Therefore, rules based on a predetermined number of examinations to reach proficiency are not satisfactory.

Abstract
Background Point-of-Care Ultrasound (PoCUS) is recommended by emergency medicine societies for the detection of hydronephrosis. Training of certified Emergency Physicians (EP) without prior ultrasound experience remains debated. We investigate performance of a brief training session for the detection of hydronephrosis with PoCUS performed by EP without previous ultrasound experience. Patients and methods This was a prospective observational study of a convenience sample of patients older than 18 years with presumed renal colic, acute pyelonephritis or documented acute renal failure. Exclusion criteria were pregnancy and documented end of life.After inclusion and informed consent, a PoCUS was performed. A radiologist’s renal ultrasound (RRUS) was then conducted, the radiologist being blind to PoCUS result.The objective was to determine the diagnostic performance of PoCUS performed by EP for the detection of hydronephrosis using RRUS as gold standard. Results Six EP participated in this study. 55 patients were included, five secondary excluded for lack of RRUS. Age was 47 ± 22 years, sex ratio 1. Hydronephrosis prevalence was 38% (CI 95% [26–52%]). Sensitivity of PoCUS was 100% (CI 95% [82–100%]) while its specificity was 71% (CI 95% [52–86%]) with a NPV of 100% (CI 95% [85–100%]) and a 68% (CI 95% [48–84%]) PPV. Kappa coefficient was 0.65 (CI 95% [0.45–0.85]). Discussion We demonstrated that a short training program enables EP without previous ultrasound skills to rule out hydronephrosis with satisfactory performances. The main limitation was the absence of collection of the number of PoCUS by EP. After this didactic course, an experiential phase must be carried out.
