Evaluation of point-of-care ultrasound use in the diagnostic approach for right upper quadrant abdominal pain management in the emergency department: a prospective study. Intern Emerg Med 2024; 19:803-811.

Abstract
Point-of-care ultrasound (PoCUS) is commonly used at the bedside in the emergency department (ED) as part of clinical examinations. Studies frequently investigate PoCUS diagnostic accuracy, although its contribution to the overall diagnostic approach is less often evaluated. The primary objective of this prospective, multicenter, cohort study was to assess the contribution of PoCUS to the overall diagnostic approach of patients with right upper quadrant abdominal pain. Two independent members of an adjudication committee, who were blind to the intervention, independently evaluated the diagnostic approaches before and after PoCUS for the same patient. The study included 62 patients admitted to the ED with non-traumatic right upper quadrant abdominal pain from September 1, 2022, to March 6, 2023. The contribution of PoCUS to the diagnostic approach was evaluated using a proportion test assuming that 75% of diagnostic approaches would be better or comparable with PoCUS. Wilcoxon signed-rank tests evaluated the impact of PoCUS on the mean number of differential diagnoses, planned treatments, and complementary diagnostic tests. Overall, 60 (97%) diagnostic approaches were comparable or better with PoCUS (χ2 = 15.9, p < 0.01). With PoCUS, the mean number of differential diagnoses significantly decreased by 2.3 (95% CI - 2.7 to - 1.5) (p < 0.01), proposed treatments by 1.3 (95% CI - 1.8 to - 0.9) (p < 0.01), and complementary diagnostic tests by 1.3 (95% CI - 1.7 to - 1.0) (p < 0.01). These findings show that PoCUS positively impacts the diagnostic approach and significantly decreases the mean number of differential diagnoses, treatments, and complementary tests.

Abstract
BACKGROUND Abdominal pain is common in patients visiting the emergency department (ED). The aim of this study was to assess the diagnostic contribution of point-of-care ultrasound (POCUS) in patients presenting to the ED with acute abdominal pain. METHODS We designed an interventional randomized, controlled, open label, parallel-group, trial in two French EDs. We included adult patients presenting to the ED with acute abdominal pain. Exclusion criteria were a documented end-of-life, an immediate need of life-support therapy and pregnant or breast-feeding women. Patients were randomized in the experimental group (i.e., workup including POCUS) or control group (usual care). The primary objective of the study was to assess the added value of POCUS on diagnostic pathway in the ED, according to the diagnostic established a posteriori by an adjudication committee. The primary endpoint was the proportion of exact preliminary diagnosis between the 2 groups. The preliminary diagnosis made after clinical examination and biological results with POCUS (intervention arm) or without POCUS (usual care) was considered exact if it was similar to the adjudication committee diagnosis. RESULTS Between June 2021 11th and June 2022 23th, 256 patients were randomized, but five were not included in the primary analysis, leaving 125 patients in the POCUS group and 126 patients in the usual care group (130 women and 121 men, median [Q1-Q3] age: 42 [30;57]). There was no difference for exact diagnosis between the two groups (POCUS 70/125, 56% versus control 78/126 (62%), RD 1.23 [95% CI 0.74-2.04]). There was no difference in the accuracy for the diagnosis of non-specific abdominal pain nor number of biological or radiological exams. Diagnostic delays and length of stay in the ED were also similar. CONCLUSIONS In this trial, systematic POCUS did not improve the rate of diagnostic accuracy in unselected patients presenting to the ED with acute abdominal pain. However, as it was a safe procedure, further research should focus on patients with suspected etiologies where POCUS is particularly useful. TRIAL REGISTRATION This trial was registered on ClinicalTrials.gov on 2022/07/20 ( https://clinicaltrials.gov/study/NCT04912206?id=NCT04912206&rank=1 ) (NCT04912206).

Abstract
BACKGROUND Patients with atraumatic abdominal pain are common in the emergency department and have a relatively high hospital mortality, with a very wide spectrum of different causes. Rapid, goal-directed diagnosis is essential in this context. METHODS In a Delphi process with representatives of different disciplines, a diagnostic treatment pathway was designed, which is called the Abdominal Pain Unit (APU). RESULTS The treatment pathway was designed as an extended event process chain. Crucial decision points were specified using standard operating procedures. DISCUSSION The APU treatment pathway establishes a consistent treatment structure for patients with atraumatic abdominal pain. It has the potential to improve the quality of care and reduce intrahospital mortality over the long term.

Abstract
Background Abdominal pain is frequent in patients consulting in emergency departments. The aim of this study is to determine the diagnosis efficacy of point-of-care ultrasound (POCUS) in patients consulting in the ED for acute abdominal pain by comparing the rate of exact diagnostic between the two arms (with or without POCUS), according to the index diagnostic established by an adjudication committee. Methods It is a randomized, controlled, open and interventional study in two emergency departments. The included patients will be adults admitted for acute abdominal pain. Exclusion criteria will be a documented end-of-life, an immediate need of life-support therapy and pregnant or breast-feeding women. Patients will be randomized in intervention (POCUS) or control groups. POCUS will only be performed by trained physicians and will be added to the diagnosis procedure in the intervention group. In the control group, the diagnosis will be established after clinical examination and reception of biological analysis results. In the interventional group, the diagnosis will be established after a clinical exam, biological analysis reception and POCUS. An adjudication committee will review all data from case report forms and will determine the index diagnosis which will be used for the analysis. The primary endpoint will be the comparison of the rate of exact diagnostic between the two arms according to the adjudication committee diagnostic. Secondary endpoints will be the comparison between the two groups for diagnostic delay, duration of ED stay, diagnostic performances for non-specific abdominal pain and hospitalization rate. The primary endpoint will be compared between the two groups using a mixed model taking into account the recruiting centre. Delays will be compared by a mixed linear generalized model. Diagnostic performances will be estimated with their 95% confidence intervals. For a correct diagnostic rate of 57% in the control group and 74% in the intervention group with a 0.05 alpha risk and a 80% power, 244 patients will be required. Discussion POCUS diagnostic abilities have been mainly demonstrated in monocentric studies but the level of evidence of its diagnostic efficacy remains controversial in particular in Europe. The aim of this study is to address this question with a rigorous methodology. Trial registration ClinicalTrials.gov NCT04912206. Registered on June 3, 2021.

Abstract
ABSTRACT We report the case of a 3-year-old boy who presented to the pediatric emergency department in undifferentiated shock with an acute abdomen. Point-of-care ultrasound revealed viscous perforation with a large amount of free fluid. Intraoperatively, a single magnet was discovered as the likely cause of bowel perforation and the resulting state of shock.

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
Abdominal pain is a common presentation in the pediatric emergency department and may pose a diagnostic challenge to the physician. Although most abdominal pain is benign, the presence of abdominal pain may represent a surgical emergency. We present an atypical presentation of perforated appendicitis in a child with 2 weeks of abdominal pain, in whom point-of-care ultrasound expedited diagnosis and patient disposition. We then recommend a diagnostic approach for using point-of-care ultrasound in a pediatric patient with undifferentiated abdominal pain.

Abstract
Diagnostic point-of-care ultrasound (POCUS) is a growing field across all disciplines of pediatric practice. Machine accessibility and portability will only continue to grow, thus increasing exposure to this technology for both providers and patients. Individuals seeking training in POCUS should first identify their scope of practice to determine appropriate applications within their clinical setting, a few of which are discussed within this article. Efforts to build standardized POCUS infrastructure within specialties and institutions are ongoing with the goal of improving patient care and outcomes.

Abstract
Background Approximately 5% of emergency department (ED) patients with altered mental status (AMS) have non-convulsive seizures (NCS). Patients with NCS should be diagnosed with EEG as soon as possible to initiate antiepileptic treatment. Since ED physicians encounter such patients first in the ED, they should be familiar with general EEG principles as well as the EEG patterns of NCS/NCSE. We evaluated the utility of a brief training module in enhancing the ED physicians’ ability to identify seizures on EEG. Methods This was a randomized controlled trial conducted in three academic institutions. A slide presentation was developed describing the basic principles of EEG including EEG recording techniques, followed by characteristics of normal and abnormal patterns, the goal of which was to familiarize the participants with EEG seizure patterns. We enrolled board-certified emergency medicine physicians into the trial. Subjects were randomized to control or intervention groups. Participants allocated to the intervention group received a self-learning training module and were asked to take a quiz of EEG snapshots after reviewing the presentation, while the control group took the quiz without the training. Results A total of 30 emergency physicians were enrolled (10 per site, with 15 controls and 15 interventions). Participants were 52% male with median years of practice of 9.5 years (3, 14). The percentage of correct answers in the intervention group (65%, 63% and 75%) was significantly different (p = 0.002) from that of control group (50%, 45% and 60%). Conclusions A brief self-learning training module improved the ability of emergency physicians in identifying EEG seizure patterns.

Abstract
Objectives: This prospective study was performed to evaluate the diagnostic accuracy of bedside point-of-care abdominal ultrasonography performed by emergency physician in patients with non-traumatic acute abdominal pain. Methods: The patients, who were admitted to emergency department due to abdominal pain, were included in this study. The emergency physician obtained a routine history, physical examination, blood draws, and ordered diagnostic imaging. After the initial clinical examinations, all the patients underwent ultrasonography for abdominal pathologies by emergency physician and radiologist, respectively. Point-of-care abdominal ultrasonography compared with abdominal ultrasonography performed by radiologist as the gold standard. Results: The study included 122 patients. Gallbladder and appendix pathologies were the most commonly detected in the abdominal ultrasonography. Compared with abdominal ultrasonography, point-of-care abdominal ultrasonography was found to have 89% sensitivity and 94% specificity in gallbladder pathologies; 91% sensitivity and 91% specificity in acute appendicitis; 79% sensitivity and 97% specificity in abdominal free fluid; 83% sensitivity and 96% specificity in ovarian pathologies. Compared to final diagnosis, preliminary diagnoses of emergency physicians were correct in 92 (75.4%) patients. Conclusion: This study showed that emergency physicians were successful in identifying abdominal organ pathologies with point-of-care abdominal ultrasonography after training.

Abstract
OBJECTIVE To assess the sensitivity and specificity of emergency physician-performed point-of-care ultrasonography (EP-POCUS) for diagnosing acute appendicitis (AA). MATERIAL AND METHODS The PubMed and EMBASE databases were searched, and the diagnostic performance of EP-POCUS was evaluated using bivariate modeling and hierarchical summary receiver operating characteristic curves. Subgroup analysis was performed for pediatric patients to compare EP-POCUS and radiologist-performed ultrasonography (RADUS). Meta-regression analyses were performed according to patient and study characteristics. RESULTS In 17 studies (2385 patients), EP-POCUS for diagnosing AA exhibited a pooled sensitivity of 84% (95% confidence interval [CI]: 72%-92%) and a pooled specificity of 91% (95% CI: 85%-95%), with even better diagnostic performance for pediatric AA (sensitivity: 95%, 95% CI: 75%-99%; specificity: 95%, 95% CI: 85%-98%). A direct comparison revealed no significant differences (p = 0.18-0.85) between the diagnostic performances of EP-POCUS (sensitivity: 81%, 95% CI: 61%-90%; specificity: 89%, 95% CI: 77%-95%) and RADUS (sensitivity: 74%, 95% CI: 65%-81%; specificity: 97%, 95% CI: 93%-98%). The meta-regression analyses revealed that study location, AA proportion, and mean age were sources of heterogeneity. Higher sensitivity and specificity tended to be associated with an appendix diameter cut-off value of 7 mm and the EP as the initial operator. CONCLUSION The diagnostic performances of EP-POCUS and RADUS were excellent for AA, with EP-POCUS having even better performance for pediatric AA. Accurate diagnoses may be achieved when the attending EP is the initial POCUS operator and uses a 7-mm cut-off value.

Abstract
Point-of-care abdominal ultrasound (US), which is performed by clinicians at bedside, is increasingly being used to evaluate clinical manifestations, to facilitate accurate diagnoses, and to assist procedures in emergency and critical care. Methods for the assessment of acute abdominal pain with point-of-care US must be developed according to accumulated evidence in each abdominal region. To detect hemoperitoneum, the methodology of a focused assessment with sonography for a trauma examination may also be an option in non-trauma patients. For the assessment of systemic hypoperfusion and renal dysfunction, point-of-care renal Doppler US may be an option. Utilization of point-of-care US is also considered in order to detect abdominal and pelvic lesions. It is particularly useful for the detection of gallstones and the diagnosis of acute cholecystitis. Point-of-case US is justified as the initial imaging modality for the diagnosis of ureterolithiasis and the assessment of pyelonephritis. It can be used with great accuracy to detect the presence of abdominal aortic aneurysm in symptomatic patients. It may also be useful for the diagnoses of digestive tract diseases such as appendicitis, small bowel obstruction, and gastrointestinal perforation. Additionally, point-of-care US can be a modality for assisting procedures. Paracentesis under US guidance has been shown to improve patient care. US appears to be a potential modality to verify the placement of the gastric tube. The estimation of the amount of urine with bladder US can lead to an increased success rate in small children. US-guided catheterization with transrectal pressure appears to be useful in some male patients in whom standard urethral catheterization is difficult. Although a greater accumulation of evidences is needed in some fields, point-of-care abdominal US is a promising modality to improve patient care in emergency and critical care settings.

Abstract
Retrograde menstruation is the backward movement of menstrual fluids. The underlying mechanisms remain unknown. The converse current itself is benign, but the result can be abdominal pain caused by peritoneal irritation and, eventually, endometriosis. The case was of a 25-year-old woman with lower abdominal pain accompanied by significant hemoperitoneum. Physical examination and inspection using abdominal ultrasonography and computed tomography failed to reveal a differential diagnosis. Detailed history taking revealed sexual activities during her menstrual period, which allowed for a diagnosis of retrograde menstruation. These findings emphasize the importance of extensive history taking.

Abstract
Cardiovascular and respiratory conditions in acute care require rapid, critical decision making, often with limited clinical information. Focused cardiac ultrasound (FOCUS) can aid in diagnosis by providing information that may not be evident from a patient's medical history, physical examination, and ancillary tests. Eight cases are presented in which FOCUS drastically altered the management of patient care, shortened the differential diagnosis, or allowed for the development of a definitive diagnosis. In 3 cases, diagnoses that were not initially suspected were identified by FOCUS. In the remaining cases, uncommon yet critical diagnoses were established at early stages along the patients' courses of care.
