RESUMEN
BACKGROUND/AIMS: Papilloedema is an important sign of serious neurological disease, but it can be difficult to detect on funduscopy. The purpose of this study was to determine the diagnostic accuracy of point-of-care ultrasound (POCUS) and optical coherence tomography (OCT) for detecting papilloedema in children. METHODS: This was a prospective observational study at a tertiary care paediatric hospital. Patients were eligible for the study if they underwent a lumbar puncture with opening pressure and had high-quality POCUS and OCT imaging. RESULTS: A total of 63 eyes from 32 patients were included in the study, 41 (65%) with papilloedema and 22 (35%) without. There were statistically significant differences between the groups in the optic disc elevation (ODE) (p<0.001) and optic nerve sheath diameter (ONSD) (p<0.001) on POCUS, and in the average retinal nerve fibre layer (rNFL) thickness on OCT (p<0.001). Average rNFL thickness had the highest diagnostic accuracy with an area under the curve (AUC) of 0.999 and a 100% sensitivity and 95% specificity for papilloedema (threshold value of ≥108 µm). ODE had an AUC of 0.866 and a 93% sensitivity and 55% specificity (threshold value of ≥0.5 mm). ONSD had an AUC of 0.786 and a 93% sensitivity and 45% specificity (threshold value of ≥5.5 mm). CONCLUSION: Both OCT and POCUS are potentially useful tools to help diagnose papilloedema in children. Larger studies are needed to further define the role and accuracy of POCUS and OCT in assessing papilloedema in children.

STUDY OBJECTIVE: Because number-based standards are increasingly controversial, the objective of this study was to derive a performance-based competency standard for the image interpretation task of point-of-care ultrasound (POCUS). METHODS: This was a prospective study. Operating on a clinically-relevant sample of POCUS images, we adapted the Ebel standard-setting method to derive a performance benchmark in 4 diverse pediatric POCUS applications: soft tissue, lung, cardiac and focused assessment with sonography in trauma (FAST). In Phase I (difficulty calibration), cases were categorized into interpretation difficulty terciles (easy, intermediate, hard) using emergency physician-derived data. In Phase II (significance), a 4-person expert panel categorized cases as low, medium, or high clinical significance. In Phase III (standard setting), a 3x3 matrix was created, categorizing cases by difficulty and significance, and a 6-member panel determined acceptable accuracy for each of the 9 cells. An overall competency standard was derived from the weighted sum. RESULTS: We obtained data from 379 emergency physicians resulting in 67,093 interpretations and a median of 184 (interquartile range, 154, 190) interpretations per case. There were 78 (19.5%) easy, 272 (68.0%) medium, and 50 (12.5%) hard-to-interpret cases, and 237 (59.3%) low, 65 (16.3%) medium, and 98 (24.5%) cases of high clinical significance across the 4 POCUS applications. The panel determined an overall performance-based competency score of 85.0% for lung, 89.5% for cardiac, 90.5% for soft tissue, and 92.7% for FAST. CONCLUSION: This research provides a transparent chain of evidence that derived clinically relevant competency standards for POCUS image interpretation.

OBJECTIVES: The aim of this study was to determine the accuracy and interrater reliability of (1) point-of-care ultrasound (POCUS) image interpretation for identification of intussusception and (2) reliability of secondary signs associated with intussusception among experts compared with novice POCUS reviewers. METHODS: We conducted a planned secondary analysis of a prospective, convenience sample of children aged 3 months to 6 years who were evaluated with POCUS for intussusception across 17 international pediatric emergency departments between October 2018 and December 2020. A random sample of 100 POCUS examinations was reviewed by novice and expert POCUS reviewers. The primary outcome was identification of the presence or absence of intussusception. Secondary outcomes included intussusception size and the presence of trapped free fluid or echogenic foci. Accuracy was summarized using sensitivity and specificity, which were estimated via generalized mixed effects logistic regression. Interrater reliability was summarized via Light's κ statistics with bootstrapped standard errors (SEs). Accuracy and reliability of expert and novice POCUS reviewers were compared. RESULTS: Eighteen expert and 16 novice POCUS reviewers completed the reviews. The average expert sensitivity was 94.5% (95% confidence interval [CI], 88.6-97.5), and the specificity was 94.3% (95% CI, 90.3-96.7), significantly higher than the average novice sensitivity of 84.7% (95% CI, 74.3-91.4) and specificity of 80.4% (95% CI, 72.4, 86.7). κ was significantly greater for expert (0.679, SE 0.039) compared with novice POCUS reviewers (0.424, SE 0.044; difference 0.256, SE 0.033). For our secondary outcome measure of intussusception size, κ was significantly greater for experts (0.661, SE 0.038) compared with novices (0.397, SE 0.041; difference 0.264, SE 0.029). Interrater reliability was weak for expert and minimal for novice reviewers regarding the detection of trapped free fluid and echogenic foci. CONCLUSIONS: Expert POCUS reviewers demonstrate high accuracy and moderate interrater reliability when identifying intussusception via image interpretation and perform better than novice reviewers.

INTRODUCTION: Point-of-care ultrasound (POCUS) is a valuable tool to determine endotracheal tube (ETT) placement; however, few studies have compared it with standard confirmation methods. We evaluated the diagnostic accuracy of POCUS and time-to-interpretation for correct identification of tracheal versus esophageal intubations compared to a composite of standard-of-care methods in neonates. METHODS: A cross-sectional study was conducted in the Neonatal Intensive Care Unit (NICU) at Aga Khan University Hospital Karachi, Pakistan. All required intubations were performed as per NICU guidelines. The clinical team simultaneously determined the ETT placement using standard-of-care methods (auscultation, colorimetric capnography, and chest X-ray) by POCUS. In addition, the clinical team was blinded to the POCUS images. Timings were recorded for each method by independent study staff. RESULTS: A total of 348 neonates were enrolled in the study. More than half (58%) of intubations were in an emergency scenario. POCUS user interpretation showed 100% sensitivity and 94% specificity using an expert as the reference standard. We found a 99.4% agreement (Kappa: 0.96; p < 0.001). Diagnostic accuracy of POCUS compared with at least two standard-of-care methods demonstrated 99.7% sensitivity, 91% specificity, and 98.9% agreement (Kappa:0.93; p < 0.001). The median time required for POCUS interpretation was 3.0 (interquartile range [IQR] 3.0-4.0) seconds for tracheal intubation. The time recorded for auscultation and capnography was 6.0 (IQR 5.0-7.0) and 3.0 (IQR 3.0-4.0), respectively. CONCLUSION: POCUS is a rapid and reliable method of identifying ETT placement in neonates. Early and correct identification of airway management is critical to save lives and prevent mortality and morbidity.

PURPOSE: To determine the interrater reliability of optic nerve sheath diameter (ONSD) and optic disc elevation (ODE) via ocular ultrasound by emergency and neurosurgery providers in children with ventricular shunts, and to explore the feasibility of acquiring and measuring images. METHODS: Two novices who underwent focused training and one expert in ocular ultrasound independently acquired images and measured ONSD and ODE on the same children, 0-18 years with ventricular shunts, blinded to each other's images and measurements. Patient tolerance, image quality, and time-to-complete exams were recorded. Images meeting a priori defined quality metrics were included. Mixed models and bootstrap analysis were used to obtain inter-rater reliability and 95% confidence intervals. RESULTS: Eighty-one children were enrolled from August 2016 to July 2017, with mean age 9.6 years (SD 5.25, range 5 months-17.7 years). High-quality images (≥ 4 on 7-point quality Likert scale) were obtained in 83% of ONSD assessments and 95% of ODE assessments. The ICCONSD was 0.82 (95% CI 0.76-0.91) for right eyes and 0.73 (95% CI 0.69-0.85) for left, while ICCODE was 0.81 (95% CI 0.75-0.89) for right eyes and 0.85 (95% CI 0.79-0.91) for left. Mean study duration (both eyes) was 2:52 min (SD 54 s). CONCLUSION: Clinicians generated high-quality ocular ultrasound images with excellent interrater reliability when acquiring and measuring images of ONSD and ODE in children with ventricular shunts.

ABSTRACT: Esophageal duplication cysts are rare congenital anomalies that are often symptomatic because of compression of surrounding structures. They are commonly diagnosed during childhood, with affected patients often presenting with abdominal pain or chest pain. Point-of-care ultrasound can be used as part of the emergency department evaluation of pediatric chest pain. We present a case of a 6-year-old boy who presented to the emergency department with worsening abdominal and chest pain, where point-of-care cardiac ultrasound identified a cystic structure in the posterior mediastinum.

Importance: The wide variation in the accuracy and reliability of the Focused Assessment With Sonography for Trauma (FAST) and the extended FAST (E-FAST) for children after blunt abdominal trauma reflects user expertise. FAST and E-FAST that are performed by experts tend to be more complete, better quality, and more often clinically valuable. Objective: To develop definitions of a complete, high-quality, and accurate interpretation for the FAST and E-FAST in children with injury using an expert, consensus-based modified Delphi technique. Design, Setting, and Participants: This consensus-based qualitative study was conducted between May 1 to June 30, 2021. It used a scoping review and iterative Delphi technique and involved 2 rounds of online surveys and a live webinar to achieve consensus among a 26-member panel. This panel consisted of international experts in pediatric emergency point-of-care ultrasonography. Main Outcomes and Measures: Definitions of complete, high-quality, and accurate FAST and E-FAST studies for children after injury. Results: Of the 29 invited pediatric FAST experts, 26 (15 men [58%]) agreed to participate in the panel. All 26 panelists completed the 2 rounds of surveys, and 24 (92%) participated in the live and asynchronous online discussions. Consensus was reached on FAST and E-FAST study definitions, and the panelists rated these 5 anatomic views as important and appropriate for a complete FAST: right upper-quadrant abdominal view, left upper-quadrant abdominal view, suprapubic views (transverse and sagittal), and subxiphoid cardiac view. For E-FAST, the same FAST anatomic views with the addition of the lung or pneumothorax view were deemed appropriate and important. In addition, the panelists rated a total of 32 landmarks as important for assessing completeness. Similarly, the panelists rated 14 statements on quality and 20 statements on accurate interpretation as appropriate. Conclusions and Relevance: This qualitative study generated definitions for complete FAST and E-FAST studies with high image quality and accurate interpretation in children with injury. These definitions are similar to those in adults with injury and may be used for future education, quality assurance, and research. Future research may focus on interpretation of trace volumes of abdominal free fluid and the use of serial FAST.

STUDY OBJECTIVE: To determine the diagnostic accuracy of point-of-care ultrasound (POCUS) performed by experienced clinician sonologists compared to radiology-performed ultrasound (RADUS) for detection of clinically important intussusception, defined as intussusception requiring radiographic or surgical reduction. METHODS: We conducted a multicenter, noninferiority, observational study among a convenience sample of children aged 3 months to 6 years treated in tertiary care emergency departments across North and Central America, Europe, and Australia. The primary outcome was diagnostic accuracy of POCUS and RADUS with respect to clinically important intussusception. Sample size was determined using a 4-percentage-point noninferiority margin for the absolute difference in accuracy. Secondary outcomes included agreement between POCUS and RADUS for identification of secondary sonographic findings. RESULTS: The analysis included 256 children across 17 sites (35 sonologists). Of the 256 children, 58 (22.7%) had clinically important intussusception. POCUS identified 60 (23.4%) children with clinically important intussusception. The diagnostic accuracy of POCUS was 97.7% (95% confidence interval [CI] 94.9% to 99.0%), compared to 99.3% (95% CI 96.8% to 99.9%) for RADUS. The absolute difference between the accuracy of RADUS and that of POCUS was 1.5 percentage points (95% CI -0.6 to 3.6). Sensitivity for POCUS was 96.6% (95% CI 87.2% to 99.1%), and specificity was 98.0% (95% CI 94.7% to 99.2%). Agreement was high between POCUS and RADUS for identification of trapped free fluid (83.3%, n=40/48) and decreased color Doppler signal (95.7%, n=22/23). CONCLUSION: Our findings suggest that the diagnostic accuracy of POCUS performed by experienced clinician sonologists may be noninferior to that of RADUS for detection of clinically important intussusception. Given the limitations of convenience sampling and spectrum bias, a larger randomized controlled trial is warranted.

OBJECTIVE: Papilledema is often difficult to detect in children. Ocular point-of-care ultrasound (POCUS) measurement of the optic nerve sheath diameter (ONSD) is a non-invasive test for increased intracranial pressure (ICP), but no consensus exists on normal pediatric ONSD values. Detection of optic disc elevation (ODE, a component of papilledema) using POCUS has recently been qualitatively described. We sought to establish the diagnostic accuracy of different ODE cutoffs to detect increased ICP in children who underwent ocular POCUS in our pediatric emergency department (PED). METHODS: We retrospectively reviewed charts of patients ages 0-18 years who received ocular POCUS in our tertiary PED between 2011 and 2016. Patients were included if their archived POCUS examinations were deemed high-quality by a POCUS expert and they underwent ICP determination within 48 h after ocular POCUS. A blinded POCUS expert measured ODE, optic disc width at mid-height (ODWAMH), and ONSD. Receiver-operator curve analysis was performed for various cutoffs for these measurements in detecting increased ICP. RESULTS: 76 eyes from 40 patients met study criteria. 26 patients had increased ICP. The mean ODE of both eyes (ODE-B) generated the largest area under the curve (0.962, 95% CI 0.890-1). The optimal ODE-B cutoff was 0.66 mm, with a sensitivity of 96% (95% CI 79-100%) and a specificity of 93% (95% CI 79-100%). 1/40 (2.5%) of patients with ODE-B < 0.66 had increased ICP. CONCLUSIONS: ODE-B may represent the optimal ocular POCUS measurement for detecting increased ICP in children, and future prospective studies could more accurately describe the diagnostic performance of different pediatric ODE-B cutoffs.

BACKGROUND: Simulators are an extensively utilized teaching tool in clinical settings. Simulation enables learners to practice and improve their skills in a safe and controlled environment before using these skills on patients. We evaluated the effect of a training session utilizing a novel intubation ultrasound simulator on the accuracy of provider detection of tracheal versus esophageal neonatal endotracheal tube (ETT) placement using point-of-care ultrasound (POCUS). We also investigated whether the time to POCUS image interpretation decreased with repeated simulator attempts. METHODS: Sixty neonatal health care providers participated in a three-hour simulator-based training session in the neonatal intensive care unit (NICU) of Aga Khan University Hospital (AKUH), Karachi, Pakistan. Participants included neonatologists, neonatal fellows, pediatric residents and senior nursing staff. The training utilized a novel low-cost simulator made with gelatin, water and psyllium fiber. Training consisted of a didactic session, practice with the simulator, and practice with intubated NICU patients. At the end of training, participants underwent an objective structured assessment of technical skills (OSATS) and ten rounds of simulator-based testing of their ability to use POCUS to differentiate between simulated tracheal and esophageal intubations. RESULTS: The majority of the participants in the training had an average of 7.0 years (SD 4.9) of clinical experience. After controlling for gender, profession, years of practice and POCUS knowledge, linear mixed model and mixed effects logistic regression demonstrated marginal improvement in POCUS interpretation over repeated simulator testing. The mean time-to-interpretation decreased from 24.7 (SD 20.3) seconds for test 1 to 10.1 (SD 4.5) seconds for Test 10, p < 0.001. There was an average reduction of 1.3 s (ß = - 1.3; 95% CI: - 1.66 to - 1.0) in time-to-interpretation with repeated simulator testing after adjusting for the covariates listed above. CONCLUSION: We found a three-hour simulator-based training session had a significant impact on technical skills and performance of neonatal health care providers in identification of ETT position using POCUS. Further research is needed to examine whether these skills are transferable to intubated newborns in various health settings. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03533218 .

OBJECTIVES: To complement bedside learning of point-of-care ultrasound (POCUS), we developed an online learning assessment platform for the visual interpretation component of this skill. This study examined the amount and rate of skill acquisition in POCUS image interpretation in a cohort of pediatric emergency medicine (PEM) physician learners. METHODS: This was a multicenter prospective cohort study. PEM physicians learned POCUS using a computer-based image repository and learning assessment system that allowed participants to deliberately practice image interpretation of 400 images from four pediatric POCUS applications (soft tissue, lung, cardiac, and focused assessment sonography for trauma [FAST]). Participants completed at least one application (100 cases) over a 4-week period. RESULTS: We enrolled 172 PEM physicians (114 attendings, 65 fellows). The increase in accuracy from the initial to final 25 cases was 11.6%, 9.8%, 7.4%, and 8.6% for soft tissue, lung, cardiac, and FAST, respectively. For all applications, the average learners (50th percentile) required 0 to 45, 25 to 97, 66 to 175, and 141 to 290 cases to reach 80, 85, 90, and 95% accuracy, respectively. The least efficient (95th percentile) learners required 60 to 288, 109 to 456, 160 to 666, and 243 to 1040 cases to reach these same accuracy benchmarks. Generally, the soft tissue application required participants to complete the least number of cases to reach a given proficiency level, while the cardiac application required the most. CONCLUSIONS: Deliberate practice of pediatric POCUS image cases using an online learning and assessment platform may lead to skill improvement in POCUS image interpretation. Importantly, there was a highly variable rate of achievement across learners and applications. These data inform our understanding of POCUS image interpretation skill development and could complement bedside learning and performance assessments.
RESUMEN
Acute inguinal swelling in young children is frequently assumed to be an inguinal hernia, often prompting a bedside reduction attempt. We report 3 cases of inguinal swelling where the use of point-of-care ultrasound changed the patients' management by identifying an alternate diagnosis, thus avoiding unnecessary and painful procedures as well as their associated sedation risks.

Impacted esophageal foreign bodies typically first present to the emergency department, with coins being most common in children and food boluses most common in adults. Controversy exists regarding the best treatment options in these cases. We report two cases, one pediatric and one adult, where the use of a novel substitute Hurst dilator constructed of materials regularly found in all EDs was successfully used to treat impacted esophageal foreign bodies.

BACKGROUND: Endotracheal tube (ETT) placement is a critical procedure for newborns that are unable to breathe. Inadvertent esophageal intubation can lead to oxygen deprivation and consequent permanent neurological impairment. Current standard-of-care methods to confirm ETT placement in neonates (auscultation, colorimetric capnography, and chest x-ray) are time consuming or unreliable, especially in the stressful resuscitation environment. Point-of-care ultrasound (POCUS) of the neck has recently emerged as a powerful tool for detecting esophageal ETTs. It is accurate and fast, and is also easy to learn and perform, especially on children. METHODS: This will be an observational diagnostic accuracy study consisting of two phases and conducted at the Aga Khan University Hospital in Karachi, Pakistan. In phase 1, neonatal health care providers that currently perform standard-of-care methods for ETT localization, regardless of experience in portable ultrasound, will undergo a two-hour training session. During this session, providers will learn to detect tracheal vs. esophageal ETTs using POCUS. The session will consist of a didactic component, hands-on training with a novel intubation ultrasound simulator, and practice with stable, ventilated newborns. At the end of the session, the providers will undergo an objective structured assessment of technical skills, as well as an evaluation of their ability to differentiate between tracheal and esophageal endotracheal tubes. In phase 2, newborns requiring intubation will be assessed for ETT location via POCUS, at the same time as standard-of-care methods. The initial 2 months of phase 2 will include a quality assurance component to ensure the POCUS accuracy of trained providers. The primary outcome of the study is to determine the accuracy of neck POCUS for ETT location when performed by neonatal providers with focused POCUS training, and the secondary outcome is to determine whether neck POCUS is faster than standard-of-care methods. DISCUSSION: This study represents the first large investigation of the benefits of POCUS for ETT confirmation in the sickest newborns undergoing intubations for respiratory support.

OBJECTIVES: Neck masses are a common reason for presentations to the pediatric emergency department (PED). We sought to determine the agreement and time difference between point-of-care ultrasound (POCUS) imaging by pediatric emergency physicians compared to radiology department imaging for children with neck masses in the PED. METHODS: We performed a retrospective study of patients aged 0 to 18 years presenting to our tertiary PED who received both POCUS by a pediatric emergency physician and radiology department imaging. Charts were reviewed for POCUS diagnoses, final diagnoses, and imaging time metrics. RESULTS: Seventy-five patients met the study criteria. In 58 of 75 cases there was agreement between the POCUS diagnosis and final diagnosis (κ = 0.71; 95% confidence interval, 0.6-0.83). There was agreement in 25 of the 28 cases in which POCUS examinations were performed by PED physicians with fellowship training in POCUS (κ = 0.87; 95% confidence interval, 0.72-1.00). The results for POCUS were generated in a median of 115 minutes (interquartile range, 68-185 minutes) before radiology department imaging results. CONCLUSIONS: Point-of-care ultrasound imaging by pediatric emergency physicians for children with neck masses is a promising new POCUS application that may be able to save time in the PED.

OBJECTIVE: Point-of-care ultrasound has become an important adjunct for diagnostic assessment in pediatric emergency medicine. In this case series, we demonstrate how ocular point-of-care ultrasound is used to correctly diagnose ocular pathologies and to expedite care. METHODS/RESULTS: We present a series of cases in which the point-of-care ultrasound ocular examination proved valuable in the timely diagnosis of pathologies involving the lens, vitreous, retina, and retrobulbar segment of the eye. CONCLUSION: Point-of-care ultrasound may facilitate diagnosis in children with ocular complaints, even in young and uncooperative patients, and should be considered in children of all ages.

Point-of-care ultrasound can be used to screen for malrotation with and without volvulus in the newborn with bilious vomiting, as well as children with unexplained intermittent abdominal pain. We discuss cases where infants and children presenting to pediatric emergency departments with bilious vomiting and/or intermittent abdominal pain were initially screened for small bowel pathology with point-of-care ultrasound. Bedside findings suggestive of midgut volvulus were confirmed with radiology-performed ultrasound or upper gastrointestinal fluoroscopy. In all cases, operative findings were consistent with malrotation of the small bowel with or without evidence of midgut volvulus.

OBJECTIVES: Point-of-care lung ultrasonography (US) is an alternative to chest radiography for imaging of suspected community-acquired pneumonia (CAP) in children. We compared pediatric emergency department (ED) time metrics between children who received point-of-care lung US versus chest radiography. Secondary objectives were comparisons of health system costs and other resources in these imaging groups. METHODS: This work was a retrospective matched cohort study of children aged 0 to 18 years in an academic urban pediatric ED who were imaged for suspected CAP with either point-of-care lung US or chest radiography. RESULTS: A total of 202 patients (101 in each group) were included in the study. The point-of-care lung US group spent a mean of 75.9 (SE, 14.3) minutes less from physician assessment to discharge (P < .0001) and 60.9 (SE, 18.1) minutes less in the overall ED length of stay (P = .0008). Physician billings and facility fees were both significantly lower (P < .0001) in the point-of-care lung US group, for a mean health systems savings of CAN$187.1 (SE, CAN$21.9). CONCLUSIONS: In children undergoing imaging for suspected CAP in our pediatric ED, point-of-care lung US by pediatric emergency medicine physicians was associated with decreased time and cost compared with chest radiography.
