Buckle me up! A randomised controlled trial using a tablet-based emergency department intervention for child car safety education.

BACKGROUND AND OBJECTIVES: Correct child car restraint use significantly reduces risk of death and serious injury in motor vehicle crashes, but millions of US children ride with improper restraints. We created a tablet-based car restraint educational intervention using Computer Intervention Authoring Software (CIAS) and examined its impact on knowledge and behaviours among parents in the paediatric emergency department (PED). METHODS: This was a non-blinded, randomised controlled trial of parents of PED patients ages 0-12 years. Participants were evaluated for baseline car restraint knowledge and behaviour. The intervention group completed an interactive tablet-based module, while the control group received printed handouts on car restraint safety. After 1 week, both groups received a follow-up survey assessing changes in car restraint knowledge and behaviour. Logistic regressions determined predictors of knowledge retention and behavioural changes. Parents in the CIAS group were also surveyed on programme acceptability. RESULTS: 211 parents completed the study with follow-up data. There was no significant difference in baseline car restraint knowledge (74.3% correct in intervention, 61.8% in control, p=0.15), or increase in follow-up restraint knowledge. Significantly more intervention-group caregivers reported modifying their child's car restraint at follow-up (52.5% vs 31.8%,p=0.003), and 93.7% of them found CIAS helpful in learning to improve car safety. CONCLUSION: Parents had overall high levels of car restraint knowledge. Using CIAS led to positive behavioural changes regarding child car restraint safety, with the vast majority reporting positive attitudes towards CIAS. This novel, interactive, tablet-based tool is a useful PED intervention for behavioural change in parents. TRIAL REGISTRATION NUMBER: NCT03799393.

Use of a Rubric for Pediatric Emergency Medicine Fellowship Application Review.

BACKGROUND: There is a need to review a large number of applications for pediatric emergency medicine fellowship in a holistic and systemic, unbiased manner. There exists a need to restructure the application process. We sought to develop and implement a rubric screening rubric for initial evaluation of pediatric emergency medicine fellowship applications that avoided traditionally used metrics that may be biased against racially underrepresented groups who are historically excluded from medicine. METHODS: An interactive process was used by key program leadership with review of prior literature and input from Diversity, Equity, and Inclusivity departmental chair to develop a holistic screening rubric with consensus reached around key factors that aligned with our fellowship program mission. All applications were reviewed with the rubric by the program director or the associate program director. A subset of applications being considered for review were additionally scored by members of the fellowship selection committee. RESULTS: Numerical scores ranged from 2 to 14, with the maximum potential score being 14. Seventy percent of those applicants invited for interview scored 9 or higher. Reliability of scores between the program director and the associate program director was high (intraclass coefficient, 0.89); however, reliability between the program director or associate program director and the selection committee members was low to moderate (intraclass coefficient, 0.46). CONCLUSIONS: Developmental and use of a rubric screening allowed our institution to reflect on our priorities, as well as avoid potential bias. The use of the tool allowed us to communicate about applications in an objective and consistent manner. As we continue to iterate on the rubric, we hope to incorporate additional criteria to better identify highly qualified applicants who may otherwise be overlooked in a traditional screening process and gain familiarity in reviewers use.

Executive summary of the SAEM 2022 consensus conference to address racism in emergency medicine clinical research, training, and leadership.

INTRODUCTION: Racism has not only contributed to disparities in health care outcomes, but also has negatively impacted the recruitment, retention, and promotion of historically excluded groups in academic medicine. The 2022 Society for Academic Emergency Medicine (SAEM) consensus conference, "Diversity, Equity, and Inclusion: Developing a Research Agenda for Addressing Racism in Emergency Medicine," convened a diverse group of researchers, educators, administrative leaders, and health care providers to help address the impact of racism in three domains in academic emergency medicine: clinical research, education and training, and academic leadership. The main goals of the consensus process were to identify current knowledge gaps and create a research agenda within each domain using an iterative consensus-building methodology. METHODS: The planning committee identified three fundamental domains to develop a research agenda and created workgroups who completed a literature search to identify gaps in knowledge. After a consensus building process, potential questions were presented at the in-person consensus conference. Ninety SAEM members representing faculty and trainees participated in breakout groups in each domain to generate consensus recommendations for priority research. RESULTS: For clinical research, three research gaps with six questions (n) were identified: remedies for bias and systematic racism (3), biases and heuristics in clinical care (2), and racism in study design (1). For education and training, three research gaps with seven questions were identified: curriculum and assessment (2), recruitment (1), and learning environment (4). For academic leadership, three research gaps with five questions were identified: understanding the current diversity, equity, and inclusion (DEI) landscape and culture (1), analyzing programs that improve DEI and identifying factors that lead to improved diversity (3), and quantifying the value of professional stewardship activities (1). CONCLUSION: This article reports the results of the consensus conference with the goal of influencing emergency care research, education, and policy and facilitating collaborations, grant funding, and publications in these domains.

Development and Validation of a Point-of-Care-Ultrasound Image Quality Assessment Tool: The POCUS IQ Scale.

OBJECTIVES: We aimed to develop a standardized scoring tool to measure point-of-care ultrasound (POCUS) image quality and to determine validity evidence for its use to assess lung ultrasound image quality. METHODS: The POCUS Image Quality (POCUS IQ) scale was developed by POCUS-trained physicians to assess sonographers' image acquisition skills by evaluating image quality for any POCUS application. The scale was piloted using lung images of healthy standardized patients acquired by three expert sonographers compared to three novices before and after training. All images (experts, novices pre-training, novices post-training) were scored on the POCUS IQ scale by three blinded POCUS-trained physicians. Reliability was assessed with fully-crossed generalizability and decision studies. Validity was assessed using Messick's framework. RESULTS: Content validity was supported by the tool's development process of literature review, expert consensus, and pilot testing. Response process was supported by reviewer training and the blinded scoring process. Relation to other variables was supported by scores relating to sonographer experience: median expert score = 10.5/14 (IQR: 4), median novice pre-training score = 6/14 (IQR: 2.25), and novices' improvement after training (median post-training score = 12/14, IQR: 3.25). Internal structure was supported by internal consistency data (coefficient alpha = 0.84, omega coefficient = 0.91) and the generalizability study showing the main contributor to score variability was the sonographer (51%). The G-coefficient was 0.89, suggesting very good internal structure, however, Gwet's AC2  was 0.5, indicating moderate interrater reliability. The D study projected a minimum of 1 reviewer and 2 patients are needed for good psychometric reliability. CONCLUSIONS: The POCUS scale has good preliminary validity evidence as an assessment tool for lung POCUS image acquisition skills. Further studies are needed to demonstrate its utility for other POCUS applications and as a feedback tool for POCUS learners.

Establishing the international research priorities for pediatric emergency medicine point-of-care ultrasound: A modified Delphi study.

BACKGROUND: The Pediatric Emergency Medicine (PEM) Point-of-care Ultrasound (POCUS) Network (P2Network) was established in 2014 to provide a platform for international collaboration among experts, including multicenter research. The objective of this study was to use expert consensus to identify and prioritize PEM POCUS topics, to inform future collaborative multicenter research. METHODS: Online surveys were administered in a two-stage, modified Delphi study. A steering committee of 16 PEM POCUS experts was identified within the P2Network, with representation from the United States, Canada, Italy, and Australia. We solicited the participation of international PEM POCUS experts through professional society mailing lists, research networks, social media, and "word of mouth." After each round, responses were refined by the steering committee before being reissued to participants to determine the ranking of all the research questions based on means and to identify the high-level consensus topics. The final stage was a modified Hanlon process of prioritization round (HPP), which emphasized relevance, impact, and feasibility. RESULTS: Fifty-four eligible participants (16.6%) provided 191 items to Survey 1 (Round 1). These were refined and consolidated into 52 research questions by the steering committee. These were issued for rating in Survey 2 (Round 2), which had 45 participants. At the completion of Round 2, all questions were ranked with six research questions reaching high-level consensus. Thirty-one research questions with mean ratings above neutral were selected for the HPP round. Highly ranked topics included clinical applications of POCUS to evaluate and manage children with shock, cardiac arrest, thoracoabdominal trauma, suspected cardiac failure, atraumatic limp, and intussusception. CONCLUSIONS: This consensus study has established a research agenda to inform future international multicenter PEM POCUS trials. This study has highlighted the ongoing need for high-quality evidence for PEM POCUS applications to guide clinical practice.

Lack of Association Between a Quantified Lung Ultrasound Score and Illness Severity in Pediatric Emergency Department Patients With Acute Lower Respiratory Infections.

OBJECTIVES: Lung ultrasound (LUS) may help determine illness severity in children with acute lower respiratory tract infections (LRTI) but limited pediatric studies exist. Our objective was to determine the association between LUS findings and illness severity in children with LRTI. METHODS: We conducted a prospective study of patients <20 years with LRTI. Trained investigators performed standardized LUS examinations of 12 regions. Blinded sonologists reviewed examinations for individual pathologic features and also calculated a Quantified Lung Ultrasound Score (QLUS). We defined focal severity as QLUS of ≥2 in ≥1 region, and diffuse severity as QLUS of ≥1 in ≥3 regions. The primary outcome was the Respiratory component of the Pediatric Early Warning Score (RPEWS), a 14-item scale measuring respiratory illness severity. Secondary outcomes included hospital admission, length of stay, supplemental oxygen, and antibiotic use. RESULTS: We enrolled 85 patients with LRTIs, 46 (54%) whom were hospitalized (5.4% intensive care). Median RPEWS was 1 (interquartile range 2). Neither individual features on ultrasound nor total QLUS were associated with RPEWS, hospitalization, length of stay, or oxygen use. Mean RPEWS was similar for participants regardless of focal (1.46 versus 1.26, P = .57) or diffuse (1.47 versus 1.21, P = .47) severity findings, but those with focal or diffuse severity, or isolated consolidation, had greater antibiotic administration (P < .001). CONCLUSIONS: In children with LRTI, neither individual features nor QLUS were associated with illness severity. Antibiotics were more likely in patients with either focal or diffuse severity or presence of consolidation on ultrasound.

Development of a Consensus-Based Definition of Focused Assessment With Sonography for Trauma in Children.

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.

Patient Outcomes With Febrile Neutropenia Based on Time to Antibiotics in the Emergency Department.

OBJECTIVE: Although bacteremia in pediatric oncology patients with febrile neutropenia (FN) is not uncommon, sepsis and mortality are rare. Because of the lack of clinically meaningful decision tools to identify high-risk patients with bacteremia, time to antibiotic administration (TTA) is increasingly considered an important quality and safety measure in the emergency department. Because little evidence exists suggesting that this benchmark is beneficial, we sought to determine whether TTA of 60 minutes or less is associated with improved outcomes. METHODS: We retrospectively reviewed patients presenting to a pediatric emergency department with FN from November 2013 to June 2016. Clinical outcomes including mortality, pediatric intensive care unit admission, imaging, fluid resuscitation of 40 mL/kg or greater in the first 24 hours, and length of stay were compared between TTA of 60 minutes or less and more than 60 minutes. RESULTS: One hundred seventy-nine episodes of FN were analyzed. The median TTA was 76 minutes (interquartile range, 58-105). The incidence of bacteremia was higher in patients with TTA of more than 60 minutes (12% vs 2%, P = 0.04), but without impact on mortality, pediatric intensive care unit admission, fluid resuscitation, or median length of stay. The median TTA was not different for those who were and were not bacteremic (91 vs 73 minutes, P = 0.11). CONCLUSIONS: Time to antibiotic administration of more than 60 minutes did not increase mortality in pediatric oncology patients with FN. Our study adds to the existing literature that TTA of 60 minutes or less does not seem to improve outcomes in pediatric FN. Further larger studies are required to confirm these findings and determine which features predispose pediatric FN patients to morbidity and mortality.

Short-term outcomes of infants born to mothers with SARS-CoV-2 infection.

OBJECTIVE: The rate of transmission of SARS-CoV-2 from mothers to infants in the peri- and post-natal period remains an area of ongoing investigation. This study aims to determine rates of development of clinically significant COVID-19 disease within 1 month among infants born to symptomatic and asymptomatic SARS-CoV-2 positive mothers. MATERIALS AND METHODS: This was a single-center, retrospective cohort study of all infants born to SARS-CoV-2 positive mothers who were admitted to the Well Baby Nursery (WBN) at New York University Langone Hospital-Brooklyn from 23 March-23 September 2020. Infants born to asymptomatic mothers were allowed to room-in, while infants born to mothers with symptoms of SARS-CoV-2 were isolated and discharged home to an alternate primary caregiver. A phone follow-up program contacted mothers at 2 weeks and 1 month post discharge to inquire about newborn symptoms, maternal symptoms, personal protective equipment (PPE) usage, and any presentations to care. Medical records were also reviewed for clinic and hospital visits to determine if exposed infants developed any symptoms following discharge. RESULTS: Of 1903 deliveries during the study period, 131 mothers (21 symptomatic, 110 asymptomatic) tested positive for SARS-CoV-2 and had infants admitted to the WBN. 57 infants (21 born to symptomatic mothers, 36 born to asymptomatic mothers) were tested prior to discharge, and none were positive. 121 of 133 infants had at least 1 follow up call in the study period. Of these, 31 had symptoms potentially concerning for SARS-CoV-2 infection or Multisystem Inflammatory Syndrome in Children, and 19 presented to medical care for these symptoms. 4 infants had SARS- CoV-2 testing after discharge, and none were positive. 2 infants were admitted to the hospital for fever but neither had a positive SARS-CoV-2 result. 65% of mothers reported always adhering to PPE recommendations. CONCLUSION: Our results suggest that infants born both to symptomatic and asymptomatic mothers are unlikely to develop clinically significant COVID-19 disease in the peri- and post-natal periods.

Point-of-Care Ultrasound Findings in Multisystem Inflammatory Syndrome in Children: A Cross-Sectional Study.

OBJECTIVES: Multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019 is a novel pediatric condition with significant morbidity and mortality. The primary objective of this investigation was to describe the point-of-care ultrasound (POCUS) findings in patients evaluated in the emergency department (ED) who were diagnosed with MIS-C. METHODS: A retrospective cross-sectional study was conducted including patients <21-years-old who had POCUS performed for clinical care in a pediatric ED and were diagnosed with MIS-C. Point-of-care ultrasound studies were performed by pediatric emergency medicine attending physicians or fellows. Data abstracted by chart review included patient demographics, clinical history, physical examination findings, diagnostic test results, the time POCUS studies and echocardiograms were performed, therapies administered, and clinical course after admission. RESULTS: For the 24 patients included, 17 focused cardiac ultrasound, 9 lung POCUS, 7 pediatric modified rapid ultrasound for shock and hypotension, 1 focused assessment with sonography for trauma, 1 POCUS for suspected appendicitis, and 1 ocular POCUS were performed by 13 physicians. Point-of-care ultrasound identified impaired cardiac contractility in 5 patients, large intraperitoneal free fluid with inflamed bowel in 1 patient, and increased optic nerve sheath diameters with elevation of the optic discs in 1 patient. Trace or small pericardial effusions, pleural effusions, and intraperitoneal free fluid were seen in 3 patients, 6 patients, and 4 patients, respectively. CONCLUSIONS: This study demonstrates the spectrum of POCUS findings in MIS-C. Prospective studies are needed to help delineate the utility of incorporating POCUS into an ED management pathway for patients with suspected MIS-C.

Point-of-Care Ultrasound for the Evaluation and Management of Febrile Infants.

BACKGROUND: Febrile infants frequently present to the emergency department (ED) and account for a vulnerable population at significant risk for serious bacterial infection. Appropriate evaluation and management are key to favorable outcomes but can present challenges for providers, especially in EDs where ill children are infrequently seen and pediatric-trained staff may not be available. Point-of-care ultrasound (POCUS) is integrated into the care of adults in the ED but is less commonly used for infants. OBJECTIVE OF REVIEW: We present a review of the current literature and proposed approach to using POCUS for bladder catheterization, lumbar puncture (LP), and vascular access in the resuscitation and evaluation of febrile infants. DISCUSSION: Point-of-care ultrasound can be a useful adjunct in the evaluation of febrile infants by facilitating higher success rates of infant bladder catheterization, LP, and intraosseous and intravenous (IV) line placement. Ultrasound has been shown to be a reliable method of evaluating bladder volumes before the catheterization of infants, reducing the number of attempts needed to obtain an adequate urine sample for testing and culture. Point-of-care ultrasound has also been shown to improve the yield of LPs in infants. Ultrasound is a rapid and accurate way of identifying the appropriate location and depth of needle insertion. Point-of-care ultrasound has also been shown to facilitate obtaining IV access in infants as well as confirming the proper placement of intraosseous lines. CONCLUSIONS: A growing body of evidence suggests that POCUS is a useful adjunct in the initial evaluation and resuscitation of febrile infants. It is the position of both the American Academy or Pediatrics, American College of Emergency Physicians, and the authors of this article that emergency physicians should be familiar with the indications and applications of POCUS in children. This technology should be used as an adjunct to improve success rates when performing bladder catheterization, LP, and obtaining intravenous/intraosseous access for infants.

Lung Point-of-Care Ultrasound in Pediatric COVID-19: A Case Series.

Lung point-of-care ultrasound (POCUS) has been shown to be useful for identifying pulmonary pathology in adult patients with coronavirus disease 2019 (COVID-19). However, pediatric literature for POCUS in COVID-19 is limited. The objective of this case series was to describe lung POCUS findings in pediatric patients with COVID-19. Three patients with COVID-19 who had lung POCUS performed in a pediatric emergency department were included. Point-of-care ultrasound revealed bilateral abnormalities in all patients, including pleural line irregularities, scattered and coalescing B-lines, consolidations, and pleural effusions. Additional pediatric studies are necessary to gain a broader understanding of COVID-19's sonographic appearance in this age group and to determine whether POCUS may be helpful to facilitate diagnosis and expedite management decisions.

Point-of-Care Ultrasound Assessment of Bladder Fullness for Female Patients Awaiting Radiology-Performed Transabdominal Pelvic Ultrasound in a Pediatric Emergency Department: A Randomized Controlled Trial.

STUDY OBJECTIVE: Radiology-performed transabdominal pelvic ultrasound, used to evaluate female patients with suspected pelvic pathology in the pediatric emergency department (ED), is often delayed by the need to fill the bladder. We seek to determine whether point-of-care ultrasound assessment of bladder fullness can predict patient readiness for transabdominal pelvic ultrasound more quickly than patient sensation of bladder fullness. METHODS: We performed a randomized controlled trial of female patients aged 8 to 18 years who required transabdominal pelvic ultrasound in a pediatric ED. Patients were randomized to usual care or point-of-care ultrasound and then assessed every 30 minutes for subjective bladder fullness (0 to 4 ordinal scale) and qualitative bladder fullness by point-of-care ultrasound. Patients were sent for pelvic ultrasound when they reported 3 or 4 on the subjective fullness scale (usual care) or a large bladder was visualized (point-of-care ultrasound). Primary outcome was time from enrollment to completion of pelvic ultrasound. Secondary outcome was success rate of pelvic ultrasound on first attempt. RESULTS: One hundred twenty patients were randomized and 117 had complete outcomes (59 usual care, 58 point-of-care ultrasound). Kaplan-Meier curves differed between groups (P<.001). Median time to successful completion of pelvic ultrasound was 139 minutes (usual care) and 87.5 minutes (point-of-care ultrasound), with difference in medians 51.5 minutes (95% confidence interval [CI] 23.4 to 77.2 minutes). All point-of-care ultrasound patients had successful transabdominal pelvic ultrasound on the first attempt compared with 84.7% in the usual care group, with difference -15.3% (95% Bayesian credible interval -5.3% to -25.0%). Weighted κ for interrater agreement was 0.83 (95% CI 0.79 to 0.87). CONCLUSION: Point-of-care ultrasound assessment of bladder fullness decreases time to transabdominal pelvic ultrasound and improves first-attempt success rate for female patients in the pediatric ED.

Measuring the Transrectal Diameter on Point-of-Care Ultrasound to Diagnose Constipation in Children.

OBJECTIVES: The aim of the study was to determine the test performance characteristics for point-of-care ultrasound in diagnosing constipation, through measuring the transrectal diameter (TRD). We sought to develop a sonographic numeric cutoff value for diagnosing constipation. Secondary objectives included whether certain patient characteristics would affect the TRD measurement and the accuracy of the TRD in comparison with abdominal radiographs. METHODS: We conducted a prospective, cohort study of pediatric patients between the age of 4 and 17 years, presenting with abdominal pain to a pediatric emergency department. A point-of-care ultrasound was performed with a phased array transducer (5-1 MHz). In addition to a thorough history and physical examination, each patient was administered with the Rome III questionnaire, which served as the criterion standard for the diagnosis of constipation. Radiographs and enema treatments were performed at the discretion of the treating attending physician. When enemas were administered, a postenema TRD measurement was obtained. RESULTS: Fifty subjects were "constipated" or "nonconstipated," as determined by the Rome III questionnaire. A TRD cutoff of 3.8 cm or greater correlated with the diagnoses of constipation (P < 0.001). Ultrasound-diagnosed constipation had a sensitivity of 86% (95% confidence interval, 69%-96%), specificity of 71% (95% CI, 53%-85%), negative predictive value of 0.87 (95% CI, 0.68-0.95), and positive predictive value of 0.70 (95% CI, 0.52-0.84). The TRD measurement was not affected by patient physical characteristics or bladder fullness. In 7 patients, an enema was administered. There was an overall mean (SD) decrease of 1.22 (1.62) cm; this difference was not statistically significant (P = 0.093). Abdominal radiographs were performed in 25 patients. When compared with abdominal radiographs, ultrasound had a higher specificity of 71% (95% CI, 53%-85%), but this difference was not statistically significant. Ultrasound performed similarly to abdominal radiographs with regard to sensitivity 86% (95% CI, 67%-95%), positive predictive value of 0.70 (95% CI, 0.52-0.84), and negative predictive value of 0.87 (0.68-0.95). In 22 of 25 patients who received radiographs, the ultrasound diagnosis was the same as the radiologist read of the radiographs. Potentially, 88% of radiographs could have been avoided in these patients. CONCLUSIONS: In pediatric patients with abdominal pain, there is a strong correlation of an enlarged TRD with constipation. Our results suggest that point-of-care ultrasound is a useful adjunct for diagnosing constipation and has the potential to replace the use of abdominal radiographs.
