Features Associated With Radiographic Pneumonia in Children with SARS-CoV-2

14% of children with SARS-CoV-2 infections had radiographic pneumonia. Hypoxemia, cough, higher temperature, and older age were associated with pneumonias. In children tested, SARS-CoV-2 test results were not associated with radiographic pneumonia.

Characteristics of Transport of Ill Pediatric Patients in the Emergency Department: A Latin America Multicenter Prospective Study

OBJECTIVE

The aim was to describe the characteristics of the transport system of critically ill pediatric patients in the emergency departments (EDs) in Latin America (LA).

METHODOLOGY

This is a prospective cross-sectional study in a 1-year period. Patients were recruited on days 1, 7, 14, 21, and 28 of each month in the EDs in LA. We included ill-pediatric patients aged 1 month to 18 years. Patients who needed transfer for a diagnostic study, with arrival mode not by ambulance, or with the impossibility of interviewing the transfer team were excluded from the study.

RESULTS

A total of 389 patients were included in the study. The majority were males (57%) with a median age of 49 months (interquartile range, 10-116). Thirty-three percent (129) of transfers had the participation of a coordinating center; 97.1% (375) were carried out by road ambulance, and 84.3% (323) were interhospital transfers, with a mean distance traveled of 83.2 km (SD, 105 km). The main reason for transfer in 88.17% (343) was the need for a more complex health center. The main diagnosis was respiratory distress (71; 18.2%), acute abdomen (70; 18%), Traumatic Brain Injury (33; 8.48%), multiple trauma (32; 8.23%), septic shock (31; 7.9%), and COVID-19-related illness (19; 4.8%). A total of 296 (76.5%) patients had peripheral vascular access, and 171 (44%) patients had oxygen support with 49 (28.6%) having invasive ventilation; the most frequent monitoring method (67.8%) was pulse oximetry, and 83.4% (313) did not record adverse events. Regarding the transfer team, 88% (342) had no specialized personnel, and only 62.4% (243) had a physician on their teams.

CONCLUSIONS

In LA, there is great variability in personnel training, equipment for pediatric transport, team composition, and characterization of critical care transport systems. Continued efforts to improve conditions in our countries may help reduce patient morbidity and mortality.

Management and outcomes of bronchiolitis in Italy and Latin America: a multi-center, prospective, observational study

We aimed to describe differences in the epidemiology, management, and outcomes existing between centers located in countries which differ by geographical location and economic status during to post-pandemic bronchiolitis seasons.  This was a prospective observational cohort study performed in two academic centers in Latin America (LA) and three in Italy. All consecutive children with a clinical diagnosis of bronchiolitis were included, following the same data collection form.  Nine hundred forty-three patients have been enrolled: 275 from the two Latin American Centers (San Jose, 215; Buenos Aires, 60), and 668 from Italy (Rome, 178; Milano, 163; Bologna, 251; Catania, 76). Children in LA had more frequently comorbidities, and only rarely received palivizumab. A higher number of patients in LA had been hospitalized in a ward (64% versus 23.9%, p < 0.001) or in a PICU (16% versus 6.2%, p < 0.001), and children in LA required overall more often respiratory support, from low flow oxygen to invasive mechanical ventilation, except for CPAP which was more used in Italy. There was no significant difference in prescription rates for antibiotics, but a significantly higher number of patients treated with systemic steroids in Italy.

CONCLUSIONS

We found significant differences in the care for children with bronchiolitis in Italy and LA. Reasons behind such differences are unclear and would require further investigations to optimize and homogenize practice all over the world.

WHAT IS KNOWN

• Bronchiolitis is among the commest cause of morbidity and mortality in infants all over the world.

WHAT IS NEW

• There are significant differences on how clinicians care for bronchiolitis in different centers and continents. Differences in care can be principally due to different local practices than differences in patients severity/presentations. • Understanding these differences should be a priority to optime and standardize bronchiolitis care globally.

A Multicenter Study on the Clinical Characteristics and Outcomes Among Children With Moderate to Severe Abusive Head Trauma

INTRODUCTION

We aimed to identify clinical characteristics, risk factors for diagnosis, and describe outcomes among children with AHT.

METHODS

We performed an observational cohort study in tertiary care hospitals from 14 countries across Asia and Ibero-America. We included patients <5 years old who were admitted to participating pediatric intensive care units (PICUs) with moderate to severe traumatic brain injury (TBI). We performed descriptive analysis and multivariable logistic regression for risk factors of AHT.

RESULTS

47 (12%) out of 392 patients were diagnosed with AHT. Compared to those with accidental injuries, children with AHT were more frequently < 2 years old (42, 89.4% vs 133, 38.6%, p < 0.001), more likely to arrive by private transportation (25, 53.2%, vs 88, 25.7%, p < 0.001), but less likely to have multiple injuries (14, 29.8% vs 158, 45.8%, p = 0.038). The AHT group was more likely to suffer subdural hemorrhage (SDH) (39, 83.0% vs 89, 25.8%, p < 0.001), require antiepileptic medications (41, 87.2% vs 209, 60.6%, p < 0.001), and neurosurgical interventions (27, 57.40% vs 143, 41.40%, p = 0.038). Mortality, PICU length of stay, and functional outcomes at 3 months were similar in both groups. In the multivariable logistic regression, age <2 years old (aOR 8.44, 95%CI 3.07-23.2), presence of seizures (aOR 3.43, 95%CI 1.60-7.36), and presence of SDH (aOR 9.58, 95%CI 4.10-22.39) were independently associated with AHT.

CONCLUSIONS

AHT diagnosis represented 12% of our TBI cohort. Overall, children with AHT required more neurosurgical interventions and the use of anti-epileptic medications. Children younger than 2 years and with SDH were independently associated with a diagnosis of AHT.

Risk Factors Associated with Intensive Care Admission in Children with Severe Acute Respiratory Syndrome Coronavirus 2-Related Multisystem Inflammatory Syndrome (MIS-C) in Latin America: A Multicenter Observational Study of the REKAMLATINA Network

Background: Multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019 varies widely in its presentation and severity, with low mortality in high-income countries. In this study in 16 Latin American countries, we sought to characterize patients with MIS-C in the pediatric intensive care unit (PICU) compared with those hospitalized on the general wards and analyze the factors associated with severity, outcomes, and treatment received. Study Design: An observational ambispective cohort study was conducted including children 1 month to 18 years old in 84 hospitals from the REKAMLATINA network from January 2020 to June 2022. Results: A total of 1239 children with MIS-C were included. The median age was 6.5 years (IQR 2.5-10.1). Eighty-four percent (1043/1239) were previously healthy. Forty-eight percent (590/1239) were admitted to the PICU. These patients had more myocardial dysfunction (20% vs 4%; P < 0.01) with no difference in the frequency of coronary abnormalities (P = 0.77) when compared to general ward subjects. Of the children in the PICU, 83.4% (494/589) required vasoactive drugs, and 43.4% (256/589) invasive mechanical ventilation, due to respiratory failure and pneumonia (57% vs 32%; P = 0.01). On multivariate analysis, the factors associated with the need for PICU transfer were age over 6 years (aOR 1.76 95% CI 1.25-2.49), shock (aOR 7.06 95% CI 5.14-9.80), seizures (aOR 2.44 95% CI 1.14-5.36), thrombocytopenia (aOR 2.43 95% CI 1.77-3.34), elevated C-reactive protein (aOR 1.89 95% CI 1.29-2.79), and chest x-ray abnormalities (aOR 2.29 95% CI 1.67-3.13). The overall mortality was 4.8%. Conclusions: Children with MIS-C who have the highest risk of being admitted to a PICU in Latin American countries are those over age six, with shock, seizures, a more robust inflammatory response, and chest x-ray abnormalities. The mortality rate is five times greater when compared with high-income countries, despite a high proportion of patients receiving adequate treatment.

Initial dysnatremia and clinical outcomes in pediatric traumatic brain injury: a multicenter observational study

PURPOSE

We aimed to investigate the association between initial dysnatremia (hyponatremia and hypernatremia) and in-hospital mortality, as well as between initial dysnatremia and functional outcomes, among children with traumatic brain injury (TBI).

METHOD

We performed a multicenter observational study among 26 pediatric intensive care units from January 2014 to August 2022. We recruited children with TBI under 18 years of age who presented to participating sites within 24 h of injury. We compared demographics and clinical characteristics between children with initial hyponatremia and eu-natremia and between those with initial hypernatremia and eu-natremia. We defined poor functional outcome as a discharge Pediatric Cerebral Performance Category (PCPC) score of moderate, severe disability, coma, and death, or an increase of at least 2 categories from baseline. We performed multivariable logistic regression for mortality and poor PCPC outcome.

RESULTS

Among 648 children, 84 (13.0%) and 42 (6.5%) presented with hyponatremia and hypernatremia, respectively. We observed fewer 14-day ventilation-free days between those with initial hyponatremia [7.0 (interquartile range (IQR) = 0.0-11.0)] and initial hypernatremia [0.0 (IQR = 0.0-10.0)], compared to eu-natremia [9.0 (IQR = 4.0-12.0); p = 0.006 and p < 0.001]. We observed fewer 14-day ICU-free days between those with initial hyponatremia [3.0 (IQR = 0.0-9.0)] and initial hypernatremia [0.0 (IQR = 0.0-3.0)], compared to eu-natremia [7.0 (IQR = 0.0-11.0); p = 0.006 and p < 0.001]. After adjusting for age, severity, and sex, presenting hyponatremia was associated with in-hospital mortality [adjusted odds ratio (aOR) = 2.47, 95% confidence interval (CI) = 1.31-4.66, p = 0.005] and poor outcome (aOR = 1.67, 95% CI = 1.01-2.76, p = 0.045). After adjustment, initial hypernatremia was associated with mortality (aOR = 5.91, 95% CI = 2.85-12.25, p < 0.001) and poor outcome (aOR = 3.00, 95% CI = 1.50-5.98, p = 0.002).

CONCLUSION

Among children with TBI, presenting dysnatremia was associated with in-hospital mortality and poor functional outcome, particularly hypernatremia. Future research should investigate longitudinal sodium measurements in pediatric TBI and their association with clinical outcomes.

Analysis of guideline recommendations for treatment of asthma exacerbations in children: a Pediatric Emergency Research Networks (PERN) study

RATIONALE

There is significant practice variation in acute paediatric asthma, particularly severe exacerbations. It is unknown whether this is due to differences in clinical guidelines.

OBJECTIVES

To describe and compare the content and quality of clinical guidelines for the management of acute exacerbations of asthma in children between geographic regions.

METHODS

Observational study of guidelines for the management of acute paediatric asthma from institutions across a global collaboration of six regional paediatric emergency research networks.

MEASUREMENTS AND MAIN RESULTS

158 guidelines were identified. Half provided recommendations for at least two age groups, and most guidelines provided treatment recommendations according to asthma severity.There were consistent recommendations for the use of inhaled short-acting beta-agonists and systemic corticosteroids. Inhaled anticholinergic therapy was recommended in most guidelines for severe and critical asthma, but there were inconsistent recommendations for its use in mild and moderate exacerbations. Other inhaled therapies such as helium-oxygen mixture (Heliox) and nebulised magnesium were inconsistently recommended for severe and critical illness.Parenteral bronchodilator therapy and epinephrine were mostly reserved for severe and critical asthma, with intravenous magnesium most recommended. There were regional differences in the use of other parenteral bronchodilators, particularly aminophylline.Guideline quality assessment identified high ratings for clarity of presentation, scope and purpose, but low ratings for stakeholder involvement, rigour of development, applicability and editorial independence.

CONCLUSIONS

Current guidelines for the management of acute paediatric asthma exacerbations have substantial deficits in important quality domains and provide limited and inconsistent guidance for severe exacerbations.

Neurological involvement in hospitalized children with SARS-CoV-2 infection: a multinational study

BACKGROUND AND OBJECTIVES

Neurological involvement associated with SARS-CoV-2 infection is increasingly recognized. However, the specific characteristics and prevalence in pediatric patients remain unclear. The objective of this study was to describe the neurological involvement in a multinational cohort of hospitalized pediatric patients with SARS-CoV-2.

METHODS

This was a multicenter observational study of children <18 years of age with confirmed SARS-CoV-2 infection or multisystemic inflammatory syndrome (MIS-C) and laboratory evidence of SARS-CoV-2 infection in children, admitted to 15 tertiary hospitals/healthcare centers in Canada, Costa Rica, and Iran February 2020-May 2021. Descriptive statistical analyses were performed and logistic regression was used to identify factors associated with neurological involvement.

RESULTS

One-hundred forty-seven (21%) of 697 hospitalized children with SARS-CoV-2 infection had neurological signs/symptoms. Headache (n = 103), encephalopathy (n = 28), and seizures (n = 30) were the most reported. Neurological signs/symptoms were significantly associated with ICU admission (OR: 1.71, 95% CI: 1.15-2.55; p = 0.008), satisfaction of MIS-C criteria (OR: 3.71, 95% CI: 2.46-5.59; p < 0.001), fever during hospitalization (OR: 2.15, 95% CI: 1.46-3.15; p < 0.001), and gastrointestinal involvement (OR: 2.31, 95% CI: 1.58-3.40; p < 0.001). Non-headache neurological manifestations were significantly associated with ICU admission (OR: 1.92, 95% CI: 1.08-3.42; p = 0.026), underlying neurological disorders (OR: 2.98, 95% CI: 1.49-5.97, p = 0.002), and a history of fever prior to hospital admission (OR: 2.76, 95% CI: 1.58-4.82; p < 0.001).

DISCUSSION

In this study, approximately 21% of hospitalized children with SARS-CoV-2 infection had neurological signs/symptoms. Future studies should focus on pathogenesis and long-term outcomes in these children.

A multicenter observational study on outcomes of moderate and severe pediatric traumatic brain injuries-time to reappraise thresholds for treatment

PURPOSE

Children with moderate traumatic brain injury (modTBI) (Glasgow Coma Scale (GCS) 9-13) may benefit from better stratification. We aimed to compare neurocritical care utilization and functional outcomes between children with high GCS modTBI (hmodTBI, GCS 11-13), low GCS modTBI (lmodTBI, GCS 9-10), and severe TBI (sTBI, GCS ≤ 8). We hypothesized that patients with lmodTBI have higher neurocritical care needs and worse outcomes than patients with hmodTBI and are similar to patients with sTBI.

METHODS

Prospective observational study from June 2018 to October 2022 in 28 pediatric intensive care units (PICU) in Asia, South America, and Europe. We included children (age < 18 years) with modTBI and sTBI admitted to PICU and measured functional outcomes at 3 months using the Glasgow Outcome Scale-Extended Pediatric Revision (GOS-E Peds, scale 1-8, 1 = upper good recovery, 8 = death).

RESULTS

We analyzed 409 patients: 98 (24%) and 311 (76%) with modTBI and sTBI, respectively. Patients with lmodTBI (vs. hmodTBI) were more likely to have invasive ICP monitoring (32.3% vs. 4.5%, p < 0.001), longer PICU stay (days, median [IQR]; 5.00 [4.00, 9.75] vs 4.00 [2.00, 5.00], p = 0.007), and longer hospital stay (days, median [IQR]: 13.00 [8.00, 17.00] vs. 8.00 [5.00, 12, 25], p = 0.015). Median GOS-E Peds scores were significantly different (hmodTBI (1.00 [1.00, 3.00]), lmodTBI (3.00 [IQR 2.00, 5.75]), and sTBI (5.00 [IQR 1.00, 6.00]) (p < 0.001)). After adjusting for age, sex, presence of polytrauma and cerebral edema, lmodTBI, and sTBI remained significantly associated with higher GOS-E scores (adjusted coefficient (standard error): 1.24 (0.52), p = 0.018, and 1.27 (0.33), p < 0.001, respectively) compared with hmodTBI.

CONCLUSIONS

Children with lmodTBI have higher rates of neurocritical care utilization and worse functional outcomes than those with hmodTBI but better than those with sTBI. Children with lmodTBI may benefit from guideline-based management similar to what is implemented in children with sTBI. This work was performed in hospitals within the PACCMAN and LARed networks. No reprints will be ordered.

Core outcomes and factors influencing the experience of care for children with severe acute exacerbations of asthma: a qualitative study

OBJECTIVE

To identify the outcomes considered important, and factors influencing the patient experience, for parents and caregivers of children presenting to hospital with a severe acute exacerbation of asthma. This work contributes to the outcome-identification process in developing a core outcome set (COS) for future clinical trials in children with severe acute asthma.

DESIGN

A qualitative study involving semistructured interviews with parents and caregivers of children who presented to hospital with a severe acute exacerbation of asthma.

SETTING

Hospitals in 12 countries associated with the global Pediatric Emergency Research Networks, including high-income and middle-income countries. Interviews were conducted face-to-face, by teleconference/video-call, or by phone.

FINDINGS

Overall, there were 54 interviews with parents and caregivers; 2 interviews also involved the child. Hospital length of stay, intensive care unit or high-dependency unit (HDU) admission, and treatment costs were highlighted as important outcomes influencing the patient and family experience. Other potential clinical trial outcomes included work of breathing, speed of recovery and side effects. In addition, the patient and family experience was impacted by decision-making leading up to seeking hospital care, transit to hospital, waiting times and the use of intravenous treatment. Satisfaction of care was related to communication with clinicians and frequent reassessment.

CONCLUSIONS

This study provides insight into the outcomes that parents and caregivers believe to be the most important to be considered in the process of developing a COS for the treatment of acute severe exacerbations of asthma.

Impact of SARS-CoV-2 Infection on the Association Between Laboratory Tests and Severe Outcomes Among Hospitalized Children

Background

To assist clinicians with identifying children at risk of severe outcomes, we assessed the association between laboratory findings and severe outcomes among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected children and determined if SARS-CoV-2 test result status modified the associations.

Methods

We conducted a cross-sectional analysis of participants tested for SARS-CoV-2 infection in 41 pediatric emergency departments in 10 countries. Participants were hospitalized, had laboratory testing performed, and completed 14-day follow-up. The primary objective was to assess the associations between laboratory findings and severe outcomes. The secondary objective was to determine if the SARS-CoV-2 test result modified the associations.

Results

We included 1817 participants; 522 (28.7%) SARS-CoV-2 test-positive and 1295 (71.3%) test-negative. Seventy-five (14.4%) test-positive and 174 (13.4%) test-negative children experienced severe outcomes. In regression analysis, we found that among SARS-CoV-2-positive children, procalcitonin ≥0.5 ng/mL (adjusted odds ratio [aOR], 9.14; 95% CI, 2.90-28.80), ferritin >500 ng/mL (aOR, 7.95; 95% CI, 1.89-33.44), D-dimer ≥1500 ng/mL (aOR, 4.57; 95% CI, 1.12-18.68), serum glucose ≥120 mg/dL (aOR, 2.01; 95% CI, 1.06-3.81), lymphocyte count <1.0 × 109/L (aOR, 3.21; 95% CI, 1.34-7.69), and platelet count <150 × 109/L (aOR, 2.82; 95% CI, 1.31-6.07) were associated with severe outcomes. Evaluation of the interaction term revealed that a positive SARS-CoV-2 result increased the associations with severe outcomes for elevated procalcitonin, C-reactive protein (CRP), D-dimer, and for reduced lymphocyte and platelet counts.

Conclusions

Specific laboratory parameters are associated with severe outcomes in SARS-CoV-2-infected children, and elevated serum procalcitonin, CRP, and D-dimer and low absolute lymphocyte and platelet counts were more strongly associated with severe outcomes in children testing positive compared with those testing negative.

Regional Perspective of Antimicrobial Stewardship Programs in Latin American Pediatric Emergency Departments

Antibiotic stewardship (AS) programs have become a priority for health authorities to reduce the number of infections by super-resistant microorganisms. The need for these initiatives to minimize the inadequate use of antimicrobials is essential, and the election of the antibiotic in the emergency department usually impacts the choice of treatment if the patients need hospital admission, becoming an opportunity for antibiotic stewardship. In the pediatric population, broad-spectrum antibiotics are more likely to be overprescribed without any evidence-based management, and most of the publications have focused on the prescription of antibiotics in ambulatory settings. Antibiotic stewardship efforts in pediatric emergency departments in Latin American settings are limited. The lack of literature on AS programs in the pediatric emergency departments in Latin America (LA) limits the information available. The aim of this review was to give a regional perspective on how pediatric emergency departments in LA are working towards antimicrobial stewardship.

International perspective on research priorities and outcome measures of importance in the care of children with acute exacerbations of asthma: a qualitative interview study

BACKGROUND

Acute exacerbations of asthma are common in children, however, treatment decisions for severe exacerbations are challenging due to a lack of robust evidence. In order to create more robust research, a core set of outcome measures needs to be developed. In developing these outcomes, it is important to understand the views of clinicians who care for these children in particular, views that relate to outcome measures and research priorities.

METHODS

To determine the views of clinicians, a total of 26 semistructured interviews based on the theoretical domains framework were conducted. These included experienced clinicians from emergency, intensive care and inpatient paediatrics across 17 countries. The interviews were recorded, and later transcribed. All data analyses were conducted in Nvivo by using thematic analysis.

RESULTS

The length of stay in hospital and patient-focused parameters, such as timing to return to school and normal activity, were the most frequently highlighted outcome measures, with clinicians identifying the need to achieve a consensus on key core outcome measure sets. Most research questions focused on understanding the best treatment options, including the role of novel therapies and respiratory support.

CONCLUSION

Our study provides an insight into what research questions and outcome measures clinicians view as important. In addition, information on how clinicians define asthma severity and measure treatment success will assist with methodological design in future trials. The current findings will be used in parallel with a further Paediatric Emergency Research Network study focusing on the child and family perspectives and will contribute to develop a core outcome set for future research.

Adherence to Pediatric Sepsis Treatment Recommendations at Emergency Departments: A Multicenter Study in Latin America

OBJECTIVE

Sepsis is one of the most urgent health care issues worldwide. Guidelines for early identification and treatment are essential to decrease sepsis-related mortality. Our aim was to collect data on the epidemiology of pediatric septic shock (PSS) from the emergency department (PED) and to assess adherence to recommendations for its management in the first hour.

METHODS

A multicenter, prospective, cross-sectional study was conducted evaluating children with PSS seen at the PED of 10 tertiary-care centers in Latin America. Adherence to guidelines was evaluated.

RESULTS

We included 219 patients (median age, 3.7 years); 43% had comorbidities, 31% risk factors for developing sepsis, 74% clinical signs of "cold shock," and 13% of "warm shock," 22% had hypotension on admission. Consciousness was impaired in 55%. A peripheral line was used as initial access in 78% (median placement time, 10 minutes). Fluid and antibiotics infusion was achieved within a median time of 30 minutes (interquartile range [IQR], 20-60 minutes) and 40 minutes (IQR, 20-60 minutes), respectively; 40% responded inadequately to fluids requiring vasoactive drugs (median time at initiation, 60 minutes; IQR, 30-135 minutes). Delay to vasoactive drug infusion was significantly longer when a central line was placed compared to a peripheral line (median time, 133 minutes [59-278 minutes] vs 42 minutes [30-70 minutes], respectively [ P < 0.001]). Adherence to all treatment goals was achieved in 13%. Mortality was 10%. An association between mortality and hypotension on admission was found (26.1% with hypotension vs 4.9% without; P < 0.001).

CONCLUSIONS

We found poor adherence to the international recommendations for the treatment of PSS in the first hour at the PED in third-level hospitals in Latin America.

Accuracy and Interrater Reliability of Point-of-Care Ultrasonography Image Interpretation for Intussusception

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.

SARS-CoV-2 infection in technology-dependent children: a multicenter case series

Purpose

The objective of this study was to describe the clinical course and outcomes in children with technology dependence (TD) hospitalized with SARS-CoV-2 infection.

Methods

Seventeen pediatric hospitals (15 Canadian and one each in Iran and Costa Rica) included children up to 17 years of age admitted February 1, 2020, through May 31, 2021, with detection of SARS-CoV-2. For those with TD, data were collected on demographics, clinical course and outcome.

Results

Of 691 children entered in the database, 42 (6%) had TD of which 22 had feeding tube dependence only, 9 were on supplemental oxygen only, 3 had feeding tube dependence and were on supplemental oxygen, 2 had a tracheostomy but were not ventilated, 4 were on non-invasive ventilation, and 2 were on mechanical ventilation prior to admission. Three of 42 had incidental SARS-CoV-2 infection. Two with end-stage underlying conditions were transitioned to comfort care and died. Sixteen (43%) of the remaining 37 cases required increased respiratory support from baseline due to COVID-19 while 21 (57%) did not. All survivors were discharged home.

Conclusion

Children with TD appear to have an increased risk of COVID-19 hospitalization. However, in the absence of end-stage chronic conditions, all survived to discharge.

Paediatric critical COVID-19 and mortality in a multinational prospective cohort

BACKGROUND

To understand critical paediatric coronavirus disease 2019 (COVID-19) and evaluate factors associated with mortality in children from high and low-middle income countries.

METHODS

Prospective, observational study of critically ill children hospitalised for COVID-19 in 18 countries throughout North America, Latin America, and Europe between April 1 and December 31, 2020. Associations with mortality were evaluated using logistic regression.

FINDINGS

557 patients (median age, 8 years; 24% <2 years) were enrolled from 55 sites (63% Latin American). Half had comorbidities. Invasive (41%) or non-invasive (20%) ventilation and vasopressors (56%) were the most common support modalities. Hospital mortality was 10% and higher in children <2 years old (15%; odds ratio 1·94, 95%CI 1·08-3·49). Most who died had pulmonary disease. When adjusted for age, sex, region, and illness severity, mortality-associated factors included cardiac (aOR 2·89; 95%CI 1·2-6·94) or pulmonary comorbidities (aOR 4·43; 95%CI 1·70-11·5), admission hypoxemia (aOR 2·44; 95%CI 1·30-4·57), and lower respiratory symptoms (aOR 2·96; 95%CI 1·57-5·59). MIS-C (aOR 0·25; 95%CI 0·1-0·61) and receiving methylprednisolone (aOR 0·5; 95%CI 0·25-0·99), IVIG (aOR 0·32; 95%CI 0·16-0·62), or anticoagulation (aOR 0·49; 95%CI 0·25-0·95) were associated with lower mortality although these associations might be limited to children >2 years old.

INTERPRETATION

We identified factors associated with COVID-19 mortality in critically ill children from both high and low-middle income countries, including higher mortality with younger age and COVID-related pulmonary disease but lower mortality in MIS-C. Further research is needed on optimal treatments for younger children and respiratory failure in paediatric COVID-19.

Risk factors for severe PCR-positive SARS-CoV-2 infection in hospitalised children

OBJECTIVE

To identify risk factors for severe disease in children hospitalised for SARS-CoV-2 infection.

DESIGN

Multicentre retrospective cohort study.

SETTING

18 hospitals in Canada, Iran and Costa Rica from 1 February 2020 to 31 May 2021.

PATIENTS

Children<18 years of age hospitalised for symptomatic PCR-positive SARS-CoV-2 infection, including PCR-positive multisystem inflammatory syndrome in children (MIS-C).

MAIN OUTCOME MEASURE

Severity on the WHO COVID-19 Clinical Progression Scale was used for ordinal logistic regression analyses.

RESULTS

We identified 403 hospitalisations. Median age was 3.78 years (IQR 0.53-10.77). At least one comorbidity was present in 46.4% (187/403) and multiple comorbidities in 18.6% (75/403). Eighty-one children (20.1%) met WHO criteria for PCR-positive MIS-C. Progression to WHO clinical scale score ≥6 occurred in 25.3% (102/403). In multivariable ordinal logistic regression analyses adjusted for age, chest imaging findings, laboratory-confirmed bacterial and/or viral coinfection, and MIS-C diagnosis, presence of a single (adjusted OR (aOR) 1.90, 95% CI 1.13 to 3.20) or multiple chronic comorbidities (aOR 2.12, 95% CI 1.19 to 3.79), obesity (aOR 3.42, 95% CI 1.76 to 6.66) and chromosomal disorders (aOR 4.47, 95% CI 1.25 to 16.01) were independent risk factors for severity. Age was not an independent risk factor, but different age-specific comorbidities were associated with more severe disease in age-stratified adjusted analyses: cardiac (aOR 2.90, 95% CI 1.11 to 7.56) and non-asthma pulmonary disorders (aOR 3.07, 95% CI 1.26 to 7.49) in children<12 years old and obesity (aOR 3.69, 1.45-9.40) in adolescents≥12 years old. Among infants<1 year old, neurological (aOR 10.72, 95% CI 1.01 to 113.35) and cardiac disorders (aOR 10.13, 95% CI 1.69 to 60.54) were independent predictors of severe disease.

CONCLUSION

We identified risk factors for disease severity among children hospitalised for PCR-positive SARS-CoV-2 infection. Comorbidities predisposing children to more severe disease may vary by age. These findings can potentially guide vaccination programmes and treatment approaches in children.

Post-COVID-19 Conditions Among Children 90 Days After SARS-CoV-2 Infection

IMPORTANCE

Little is known about the risk factors for, and the risk of, developing post-COVID-19 conditions (PCCs) among children.

OBJECTIVES

To estimate the proportion of SARS-CoV-2-positive children with PCCs 90 days after a positive test result, to compare this proportion with SARS-CoV-2-negative children, and to assess factors associated with PCCs.

DESIGN, SETTING, AND PARTICIPANTS

This prospective cohort study, conducted in 36 emergency departments (EDs) in 8 countries between March 7, 2020, and January 20, 2021, included 1884 SARS-CoV-2-positive children who completed 90-day follow-up; 1686 of these children were frequency matched by hospitalization status, country, and recruitment date with 1701 SARS-CoV-2-negative controls.

EXPOSURE

SARS-CoV-2 detected via nucleic acid testing.

MAIN OUTCOMES AND MEASURES

Post-COVID-19 conditions, defined as any persistent, new, or recurrent health problems reported in the 90-day follow-up survey.

RESULTS

Of 8642 enrolled children, 2368 (27.4%) were SARS-CoV-2 positive, among whom 2365 (99.9%) had index ED visit disposition data available; among the 1884 children (79.7%) who completed follow-up, the median age was 3 years (IQR, 0-10 years) and 994 (52.8%) were boys. A total of 110 SARS-CoV-2-positive children (5.8%; 95% CI, 4.8%-7.0%) reported PCCs, including 44 of 447 children (9.8%; 95% CI, 7.4%-13.0%) hospitalized during the acute illness and 66 of 1437 children (4.6%; 95% CI, 3.6%-5.8%) not hospitalized during the acute illness (difference, 5.3%; 95% CI, 2.5%-8.5%). Among SARS-CoV-2-positive children, the most common symptom was fatigue or weakness (21 [1.1%]). Characteristics associated with reporting at least 1 PCC at 90 days included being hospitalized 48 hours or more compared with no hospitalization (adjusted odds ratio [aOR], 2.67 [95% CI, 1.63-4.38]); having 4 or more symptoms reported at the index ED visit compared with 1 to 3 symptoms (4-6 symptoms: aOR, 2.35 [95% CI, 1.28-4.31]; ≥7 symptoms: aOR, 4.59 [95% CI, 2.50-8.44]); and being 14 years of age or older compared with younger than 1 year (aOR, 2.67 [95% CI, 1.43-4.99]). SARS-CoV-2-positive children were more likely to report PCCs at 90 days compared with those who tested negative, both among those who were not hospitalized (55 of 1295 [4.2%; 95% CI, 3.2%-5.5%] vs 35 of 1321 [2.7%; 95% CI, 1.9%-3.7%]; difference, 1.6% [95% CI, 0.2%-3.0%]) and those who were hospitalized (40 of 391 [10.2%; 95% CI, 7.4%-13.7%] vs 19 of 380 [5.0%; 95% CI, 3.0%-7.7%]; difference, 5.2% [95% CI, 1.5%-9.1%]). In addition, SARS-CoV-2 positivity was associated with reporting PCCs 90 days after the index ED visit (aOR, 1.63 [95% CI, 1.14-2.35]), specifically systemic health problems (eg, fatigue, weakness, fever; aOR, 2.44 [95% CI, 1.19-5.00]).

CONCLUSIONS AND RELEVANCE

In this cohort study, SARS-CoV-2 infection was associated with reporting PCCs at 90 days in children. Guidance and follow-up are particularly necessary for hospitalized children who have numerous acute symptoms and are older.

Predictors of severe illness in children with multisystem inflammatory syndrome after SARS-CoV-2 infection: a multicentre cohort study

BACKGROUND

SARS-CoV-2 infection can lead to multisystem inflammatory syndrome in children (MIS-C). We sought to investigate risk factors for admission to the intensive care unit (ICU) and explored changes in disease severity over time.

METHODS

We obtained data from chart reviews of children younger than 18 years with confirmed or probable MIS-C who were admitted to 15 hospitals in Canada, Iran and Costa Rica between Mar. 1, 2020, and Mar. 7, 2021. Using multivariable analyses, we evaluated whether admission date and other characteristics were associated with ICU admission or cardiac involvement.

RESULTS

Of 232 children with MIS-C (median age 5.8 yr), 130 (56.0%) were male and 50 (21.6%) had comorbidities. Seventy-three (31.5%) patients were admitted to the ICU but none died. We observed an increased risk of ICU admission among children aged 13-17 years (adjusted risk difference 27.7%, 95% confidence interval [CI] 8.3% to 47.2%), those aged 6-12 years (adjusted risk difference 25.2%, 95% CI 13.6% to 36.9%) or those with initial ferritin levels greater than 500 μg/L (adjusted risk difference 18.4%, 95% CI 5.6% to 31.3%). Children admitted to hospital after Oct. 31, 2020, had numerically higher rates of ICU admission (adjusted risk difference 12.3%, 95% CI -0.3% to 25.0%) and significantly higher rates of cardiac involvement (adjusted risk difference 30.9%, 95% CI 17.3% to 44.4%). At Canadian sites, the risk of ICU admission was significantly higher for children admitted to hospital between December 2020 and March 2021 than those admitted between March and May 2020 (adjusted risk difference 25.3%, 95% CI 6.5% to 44.0%).

INTERPRETATION

We observed that age and higher ferritin levels were associated with more severe MIS-C. We observed greater severity of MIS-C later in the study period. Whether emerging SARS-CoV-2 variants pose different risks of severe MIS-C needs to be determined.

Streptococcus Pyogenes Epiglottitis in a Child: A Case Report

Acute epiglottitis in children is a rare entity since the introduction of the vaccine against Haemophilus influenzae; however, it should be considered as part of the differential diagnosis when facing a patient with evidence of upper airway obstruction. This study describes the case of a three-year-old child who arrived at the emergency department with fever, respiratory distress, and stridor. After ventilatory failure, the patient was intubated and antibiotics were initiated. The results of the bacteria culture confirmed Streptococcus pyogenes infection. This case report intends to describe and review the differential diagnoses of epiglottitis, as well as its management and prognosis.

Triage and resuscitation tools for low and middle income countries: how to catch the killer?

Under-5 mortality rates in low and middle-income countries (LMIC) remain high. One major contributing factor is the failure to recognise critically unwell children when they first present to hospital. This leads to delayed or inadequate resuscitation and an increased risk of death.Triage is a key skill in this setting to sort the queue and prioritise patients, even when staff and equipment are scarce. In LMIC, children generally present late in their illness and often have progressed to some degree of multiorgan dysfunction.Following triage, a structured systematic primary survey is critical to ensure the detection of subtle signs of multiorgan dysfunction. Repeated physiological assessments of the child guide subsequent resuscitation management decisions, which depend somewhat on the resources available.It is possible to achieve significant improvements in survival of critically unwell children presenting for emergency care in the resource-limited setting. The three key steps in the patient's journey that we can influence in emergency care are triage, primary survey and initial stabilisation. Resources that address these steps have been developed for all settings. However, these resources were developed in a specific clinical context, and must therefore be adapted to local structures and processes. A systematic approach to triage and resuscitation saves lives.

Pediatric Emergency Medicine Training: A Survey of Current Status in Latin America

Pediatric emergency medicine (PEM) is a relatively new and rapidly evolving subspecialty in many countries. The purposes of this study were to describe the characteristics and to find common/shared practices in current available PEM fellowship programs across Latin America.

METHODS

An electronic, multicenter survey was created and stored on Google forms. The survey was in Spanish language and included 30 questions about the characteristics of the pediatric emergency program, history of the program, and support expected from the Latin American Pediatric Emergency Society.

RESULTS

A total of 11 PEM programs in 6 countries were acknowledged in Latin America. All programs are placed in pediatric tertiary care hospitals. All PEM programs were approved by the local universities and the Ministries of Health in each country. Difficulties to start a PEM program included a lack of physicians properly trained in PEM who could direct the program, physician instructors in specific topics, places to complete rotations of the future fellows, and getting the local health authorities to acknowledge the importance of the program. With regard to the duration of the program, 72.7% (8) have a 2-year curriculum and 27.3% (3) have a 1-year curriculum. Four (36.4%) program directors mentioned an admission examination as a requirement, 4 (36.4%) needed an examination plus an interview, 3 (27.3%) mentioned that it is necessary just like an interview, and 2 (18.2%) mentioned that the physicians are admitted with a scholarship. With regard to the structure of the programs and rotations included, most of the programs have rotations that are compulsory in different pediatric subspecialties. In 80% of the programs, fellows are evaluated based on different technical skill procedures that they need to learn and perform during PEM fellowship training. The PEM fellowship is recognized by different societies in emergency medicine and pediatrics, except in Dominican Republic where it is only recognized by the Ministry of Health and the university. After completion of the program in 90% (10) of the programs, graduates are not guaranteed a job, and in half, there is no mechanism implemented for recertification of the pediatric emergency physicians by the local medical council.

CONCLUSIONS

In Latin America, postgraduate programs in pediatric emergencies are a response to a need for health systems. Being an innovative specialty, it surpassed each country's own challenges, until it was able to reach an internationally standardized level, with a great diversity of pedagogical methodology, which the product has been to offer a high quality of emergency care to children.

Outcomes of SARS-CoV-2-Positive Youths Tested in Emergency Departments: The Global PERN-COVID-19 Study

IMPORTANCE

Severe outcomes among youths with SARS-CoV-2 infections are poorly characterized.

OBJECTIVE

To estimate the proportion of children with severe outcomes within 14 days of testing positive for SARS-CoV-2 in an emergency department (ED).

DESIGN, SETTING, AND PARTICIPANTS

This prospective cohort study with 14-day follow-up enrolled participants between March 2020 and June 2021. Participants were youths aged younger than 18 years who were tested for SARS-CoV-2 infection at one of 41 EDs across 10 countries including Argentina, Australia, Canada, Costa Rica, Italy, New Zealand, Paraguay, Singapore, Spain, and the United States. Statistical analysis was performed from September to October 2021.

EXPOSURES

Acute SARS-CoV-2 infection was determined by nucleic acid (eg, polymerase chain reaction) testing.

MAIN OUTCOMES AND MEASURES

Severe outcomes, a composite measure defined as intensive interventions during hospitalization (eg, inotropic support, positive pressure ventilation), diagnoses indicating severe organ impairment, or death.

RESULTS

Among 3222 enrolled youths who tested positive for SARS-CoV-2 infection, 3221 (>99.9%) had index visit outcome data available, 2007 (62.3%) were from the United States, 1694 (52.6%) were male, and 484 (15.0%) had a self-reported chronic illness; the median (IQR) age was 3 (0-10) years. After 14 days of follow-up, 735 children (22.8% [95% CI, 21.4%-24.3%]) were hospitalized, 107 (3.3% [95% CI, 2.7%-4.0%]) had severe outcomes, and 4 children (0.12% [95% CI, 0.03%-0.32%]) died. Characteristics associated with severe outcomes included being aged 5 to 18 years (age 5 to <10 years vs <1 year: odds ratio [OR], 1.60 [95% CI, 1.09-2.34]; age 10 to <18 years vs <1 year: OR, 2.39 [95% CI 1.38-4.14]), having a self-reported chronic illness (OR, 2.34 [95% CI, 1.59-3.44]), prior episode of pneumonia (OR, 3.15 [95% CI, 1.83-5.42]), symptoms starting 4 to 7 days prior to seeking ED care (vs starting 0-3 days before seeking care: OR, 2.22 [95% CI, 1.29-3.82]), and country (eg, Canada vs US: OR, 0.11 [95% CI, 0.05-0.23]; Costa Rica vs US: OR, 1.76 [95% CI, 1.05-2.96]; Spain vs US: OR, 0.51 [95% CI, 0.27-0.98]). Among a subgroup of 2510 participants discharged home from the ED after initial testing and who had complete follow-up, 50 (2.0%; 95% CI, 1.5%-2.6%) were eventually hospitalized and 12 (0.5%; 95% CI, 0.3%-0.8%) had severe outcomes. Compared with hospitalized SARS-CoV-2-negative youths, the risk of severe outcomes was higher among hospitalized SARS-CoV-2-positive youths (risk difference, 3.9%; 95% CI, 1.1%-6.9%).

CONCLUSIONS AND RELEVANCE

In this study, approximately 3% of SARS-CoV-2-positive youths tested in EDs experienced severe outcomes within 2 weeks of their ED visit. Among children discharged home from the ED, the risk was much lower. Risk factors such as age, underlying chronic illness, and symptom duration may be useful to consider when making clinical care decisions.

Infants hospitalized for acute COVID-19: disease severity in a multicenter cohort study

Age is the most important determinant of COVID-19 severity. Infectious disease severity by age is typically J-shaped, with infants and the elderly carrying a high burden of disease. We report on the comparative disease severity between infants and older children in a multicenter retrospective cohort study of children 0 to 17 years old admitted for acute COVID-19 from February 2020 through May 2021 in 17 pediatric hospitals. We compare clinical and laboratory characteristics and estimate the association between age group and disease severity using ordinal logistic regression. We found that infants comprised one-third of cases, but were admitted for a shorter period (median 3 days IQR 2-5 versus 4 days IQR 2-7), had a lower likelihood to have an increased C-reactive protein, and had half the odds of older children of having severe or critical disease (OR 0.50 (95% confidence interval 0.32-0.78)).    Conclusion: When compared to older children, there appeared to be a lower threshold to admit infants but their length of stay was shorter and they had lower odds than older children of progressing to severe or critical disease. What is Known: • A small proportion of children infected with SARS-CoV-2 require hospitalization for acute COVID-19 with a subgroup needing specialized intensive care to treat more severe disease. • For most infectious diseases including viral respiratory tract infections, disease severity by age is J-shaped, with infants having more severe disease compared to older children. What is New: • One-third of admitted children for acute COVID-19 during the first 14 months of the pandemic were infants. • Infants had half the odds of older children of having severe or critical disease.

Pediatric Critical Care Transport: Survey of Current State in Latin America. Latin American Society of Pediatric Intensive Care Transport Committee

METHODS

An electronic, anonymous, multicenter survey housed by Monkey Survey was sent to physicians in LA and included questions about hospital and pediatric critical transport, resources available and level of car. Nineteen Latin-American countries were asked to complete the survey.

RESULTS

A total of 212 surveys were analyzed, achieving a representativity of 19 LA countries, being most participants (59.4%, n = 126) from South America (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, Uruguay and Venezuela). Most surveys were conducted by physicians of tertiary level centers (60.8%, n = 129), most of the institutions were classified by the participants as public health care centers (81.6%, n = 173). Most of the surveyed physicians (63.7%, n = 135) reported that there is a coordination center for critical care transport (CCT). In most cases, physicians report that a unified transport system for pediatric critical patients does not exist in their countries (67.45%, n = 143). Only 59 (30.7%) surveys reported the use of an exclusively pediatric critical care transport system. Most of these transport systems are described as a mixture of public and private efforts (51.56%, n = 99), but there is also a considerable involvement of government-funded critical transport systems (43.75%, n = 84). Specific training for personnel devoted to transportation of critically ill patients is reported in 55.6% (90), and the medical equipment necessary to carry out the transport is available in 67.7%. The majority (83.95%, n = 136) mentioned that access to advanced life support courses is possible. Training in triage and disaster is available in 44.1%. Physicians and registered nurse were identified as the transport providers in 41.5%, and only one third were made by pediatricians-pediatric nurse. The main reasons for transfers were respiratory illness, neonatal pathologies, trauma, infectious diseases, and neurological conditions. Overall, pediatric transport was reported as insufficient (70.19%, n = 148) by the surveyed physicians in LA and nonexisting by some of them (6.83%, n = 15). There were no regulations or laws in the majority of the surveyed countries (63.13%), and in the places where physicians reported regulatory laws, there were no dissemination (84.9%) by the local authorities.

CONCLUSIONS

In LA, there is a great variability in personnel training, equipment for pediatric-neonatal transport, transport team composition, and characterization of critical care transport systems. Continued efforts to improve conditions in our countries by generating documents that standardize practices and generating scientific information on the epidemiology of pediatric transfers, especially of critically ill patients, may help reduce patient morbidity and mortality.

[Latin American Consensus on Pediatric Cardiopulmonary Resuscitation. An Executive Summary from the CPR Committee, Latin American Society of Pediatric Intensive Care (SLACIP)]

Cardiopulmonary Resuscitation (CPR) is a critical procedure with potential consequences over futu re vitality and functionality in survivors. In this document, we present a pragmatic and regional point of view on diagnosis, management, and prognostication in pediatric CPR developed by the Com mittee on CPR of the Latin American Society of Pediatric Intensive Care (SLACIP). We have chosen the main CPR topics with the aim of contribute for a better prevention and management of CPR, standardize the management of the post-cardiac arrest syndrome and neuro-prognostication, and identify opportunities for regional research. We have followed the Executive Summary published in 2020 by the International Liaison Committee on Resuscitation, ILCOR, adapted it to our reality, and developed this narrative review of pediatric CPR with the contribution of Latin American experts.

Latin American Consensus on the Management of Sepsis in Children: Sociedad Latinoamericana de Cuidados Intensivos Pediátricos [Latin American Pediatric Intensive Care Society] (SLACIP) Task Force: Executive Summary

OBJECTIVE

The aim of this study was to develop evidence-based recommendations for the diagnosis and treatment of sepsis in children in low- and middle-income countries (LMICs), more specifically in Latin America. Design: A panel was formed consisting of 27 experts with experience in the treatment of pediatric sepsis and two methodologists working in Latin American countries. The experts were organized into 10 nominal groups, each coordinated by a member. Methods: A formal consensus was formed based on the modified Delphi method, combining the opinions of nominal groups of experts with the interpretation of available scientific evidence, in a systematic process of consolidating a body of recommendations. The systematic search was performed by a specialized librarian and included specific algorithms for the Cochrane Specialized Register, PubMed, Lilacs, and Scopus, as well as for OpenGrey databases for grey literature. The GRADEpro GDT guide was used to classify each of the selected articles. Special emphasis was placed on search engines that included original research conducted in LMICs. Studies in English, Spanish, and Portuguese were covered. Through virtual meetings held between February 2020 and February 2021, the entire group of experts reviewed the recommendations and suggestions. Result: At the end of the 12 months of work, the consensus provided 62 recommendations for the diagnosis and treatment of pediatric sepsis in LMICs. Overall, 60 were strong recommendations, although 56 of these had a low level of evidence. Conclusions: These are the first consensus recommendations for the diagnosis and management of pediatric sepsis focused on LMICs, more specifically in Latin American countries. The consensus shows that, in these regions, where the burden of pediatric sepsis is greater than in high-income countries, there is little high-level evidence. Despite the limitations, this consensus is an important step forward for the diagnosis and treatment of pediatric sepsis in Latin America.

How Are Clinicians Treating Children With Sepsis in Emergency Departments in Latin America?: An International Multicenter Survey

OBJECTIVE

Guidelines adherence in emergency departments (EDs) relies partly on the availability of resources to improve sepsis care and outcomes. Our objective was to assess the management of pediatric septic shock (PSS) in Latin America's EDs and to determine the impact of treatment coordinated by a pediatric emergency specialist (PEMS) versus nonpediatric emergency specialists (NPEMS) on guidelines adherence.

METHODS

Prospective, descriptive, and multicenter study using an electronic survey administered to PEMS and NPEMS who treat PSS in EDs in 14 Latin American countries.

RESULTS

We distributed 2164 surveys with a response rate of 41.5%, of which 22.5% were PEMS. Overall American College of Critical Care Medicine reported guidelines adherence was as follows: vascular access obtained in 5 minutes, 76%; fluid infusion technique, 60%; administering 40 to 60 mL/kg within 30 minutes, 32%; inotropic infusion by peripheral route, 61%; dopamine or epinephrine in cold shock, 80%; norepinephrine in warm shock, 57%; and antibiotics within 60 minutes, 82%. Between PEMS and NPEMS, the following differences were found: vascular access in 5 minutes, 87.1% versus 72.7% (P < 0.01); fluid infusion technique, 72.3% versus 55.9% (P < 0.01); administering 40 to 60 mL/kg within 30 minutes, 42% versus 29% (P < 0.01); inotropic infusion by peripheral route, 75.7% versus 56.3% (P < 0.01); dopamine or epinephrine in cold shock, 87.1% versus 77.3% (P < 0.05); norepinephrine in warm shock, 67.8% versus 54% (P < 0.01); and antibiotic administration within first 60 minutes, 90.1% versus 79.3% (P < 0.01), respectively. Good adherence criteria were followed by 24%. The main referred barrier for sepsis care was a failure in its recognition, including the lack of triage tools.

CONCLUSIONS

In some Latin American countries, there is variability in self-reported adherence to the evidence-based recommendations for the treatment of PSS during the first hour. The coordination by PEMS support greater adherence to these recommendations.

Acute Abdomen and Appendicitis in 1010 Pediatric Patients With COVID-19 or MIS-C: A Multinational Experience from Latin America

BACKGROUND

To date, there are only sporadic reports of acute abdomen and appendicitis in children with coronavirus disease 2019 (COVID-19) and multisystem inflammatory syndrome in children (MIS-C).

METHODS

Children 17 years of age or younger assessed in 5 Latin American countries with a diagnosis of microbiologically confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and children fulfilling MIS-C definition were included. For children with acute abdomen, we investigate main radiologic patterns, surgical treatment and intraoperative findings, outcomes.

FINDINGS

One-thousand ten children were enrolled. Forty-two children (4.2%) had a clinical diagnosis of acute abdomen. Four (9.5%) were diagnosed with MIS-C and did not undergo surgery. The remaining 38 children (3.8%) underwent abdominal surgery due to suspected appendicitis, 34 of them (89.7%) had an intraoperative diagnosis of acute appendicitis (AA), while 4 of them had nonsurgical findings. Eight children died (0.8%), none of them being diagnosed with appendicitis. Children with AA were significantly older than those without (P < 0.0001). Children with complicated appendicitis had more frequently fever (85.7% vs. 60%), intestinal distension on the abdominal radiograph (7.1% vs. none), leukocytosis (85.7% vs. 40%) and high levels of C-reactive protein (35.7% vs. 5%), although differences were not statistically significant.

CONCLUSIONS

Our study showed that children may present with acute abdomen during COVID-19 or MIS-C, which is not always associated with intraoperative findings of appendicitis, particularly in case of MIS-C. Further studies are needed to better characterize children with acute abdomen during COVID-19 or MIS-C, to avoid delay in diagnosis of surgical conditions and at the same time, minimize unnecessary surgical approaches.

Validation of the Pediatric Canadian Triage and Acuity Scale at the Emergency Department of a Tertiary Children's Hospital in Costa Rica

Background: The Pediatric Canadian Triage and Acuity Scale (PedCTAS) is a recognized system that prioritizes care by the severity of illness. The goal of this study was to describe and analyze the results from the implementation of the PedCTAS in a tertiary children’s hospital in Costa Rica.

Methods: This was a retrospective observational study of children presenting to the emergency department (ED) from 1st January to 31st December of 2019 in the only children’s hospital in Costa Rica. Outcome measures were hospitalization, ICU admission, waiting times from triage to physician time (TPT), left without being seen (LWBS), length of stay (LOS), in relation to the triage level, and final disposition.

Results: A total of 93,001 patients were admitted to the ED. The proportion for hospitalizations according to triage category was 85.3%, 40%, 14%, 4.3%, and 2% for patients triaged at CTAS levels I, II, III, IV, and V respectively. A total of 2045 (2.19%) patients were LWBS. Some 585 (0.62%) patients were admitted to ICU. Median TPT for each category was for levels I:12 min, II:20 min, III:22 min, IV:34 min, and V:54 min. The LOS in the ED patients triaged as levels I and II stayed longer and the mortality rate was also higher in patients classified as levels I and II. The mortality rate was for level I patients 44.2% (23 patients) and level II 1.4% (8 patients).

Conclusions: This study shows evidence of validation of the PedCTAS in a developing country in Latin America. Implementation of a validated triage tool in our country helps us to provide improvements in the care of pediatric patients in the ED.

Diagnostic Accuracy of Point-of-Care Ultrasound for Intussusception: A Multicenter, Noninferiority Study of Paired Diagnostic Tests

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.

Tendencias en las consultas a los servicios de emergencias durante la pandemia por covid-19

  Objetivo: En Costa Rica se observó una disminución en las atenciones en los Servicios de Emergencias al inicio de la pandemia por lo que el objetivo de este estudio es la descripción de este fenómeno, su duración, así como implicaciones en nuestro país.Métodos: Es un estudio descriptivo observacional retrospectivo de las atenciones en los Servicios de Emergencias de los Hospitales pertenecientes a la Caja Costarricense del Seguro Social durante el 1 de enero al 31 de diciembre del 2020.Resultados: Se incluyeron 25 Servicios de Emergencias. Las atenciones durante el periodo de estudio fueron de 1.549.024 millones de visitas y la cantidad de revaloraciones a 4,038,029. El rango de atenciones en los diferentes SEM tuvo un rango de 19070 mil a 122251 mil durante el periodo del estudio. Se observó que 850 707 (54,9%) eran del sexo femenino. La mayor cantidad de pacientes atendidos en los SEM tenían edades entre los 20 a 44 años con 693 379 (44.7%) atenciones, seguido del grupo entre los 45 a 64 años con 328 979 (21.2%). Lo que respecta a la clasificación de la agudeza de los pacientes por medio del sistema de triaje canadiense, un 40% (620 449) fueron catalogados como categoría 3, un 39.8%(616 855) categoría 4, 14%(218 124), 5.3%(82 360) categoría 2 y por último 0.6%(9206) pacientes como categoría 1. Respeto a pacientes con el diagnóstico asociado a SARS CoV-2 se observó que 88 793 en los Servicios de Emergencias tuvieron dichos diagnósticos durante el periodo del estudio.Conclusiones: La tendencia a la baja en las consultas al Servicio de Emergencias en Costa Rica, reproduce las tendencias reportadas en la bibliografía a nivel mundial. La explicación para este fenómeno es multifactorial. Existen una gran cantidad de cambios “estructurales” tanto en los servicios de emergencias como en hospitalización y el sistema de salud en general, que con mucha probabilidad deberán cambiarse de manera definitiva y prioritaria. No solo para la atención de esta pandemia sino con miras a que dichos sistemas se encuentren mejor preparados para próximos eventos infecciosos de cualquier tipo.

[Epidemiology, clinical manifestations and microbiology of children with necrotizing fasciitis in a Costa Rican pediatric hospital]

BACKGROUND

Despite the significant associated morbidity of necrotizing fasciitis (NF), few studies have been published and this is the larger pediatric series in Latin America.

AIM

To describe the epidemiology, clinical characteristics and microbiology of NF in Costa Rican children.

METHODS

Review of clinical and pathological records, period April 2002 to April 2014, in patients under 13 years of age.

RESULTS

19/22 patients met the inclusion requirement, 12 had co-morbidity: 26% with a history of recent surgery and 21% were neonates. Etiology was documented in blood cultures in 26% and by tissue culture in 63% (one third of them polymicrobial). Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus were the three most common etiologic agents. Case fatality rate was 42%, one of the highest in our region.

CONCLUSION

NF is a serious, unusual pathology, frequently associated with neonatology and post-surgical patients, with a mixed etiology that requires the association of antimicrobials and early surgery. Its lethality is high in our setting, over previously published series.

Differentiating arterial ischaemic stroke from migraine in the paediatric emergency department

AIM

To estimate the strengths of association between clinical features and migraine or arterial ischaemic stroke (AIS) in children presenting to the emergency department.

METHOD

Eighty-four children with migraine, prospectively recruited from 2009 to 2010, were compared with 55 children with AIS, prospectively/retrospectively recruited from 2003 to 2010. Odds ratios were calculated via logistic regression to measure associations between clinical features and process-of-care factors, and migraine and AIS.

RESULTS

Median age was 13 years 5 months (interquartile range 12y 11mo-13y 10mo) for migraine and 5 years (interquartile range 3y 7mo-8y) for patients with AIS. All cases of AIS and 30% of migraine cases underwent neuroimaging. Over 40% of children with migraine had vomiting, numbness, or visual disturbance; other symptoms were uncommon. Fifty-five per cent had no signs on physician assessment. Weakness or speech disturbance were common in patients with AIS. Significant clinical features associated with increased odds of AIS included sudden symptom onset, weakness, seizures, speech disturbance, and ataxia, and signs of face, arm, or leg weakness, inability to walk, dysarthria, dysphasia, and altered consciousness (p<0.05). Significant features associated with decreased odds of AIS included older age, vomiting, visual, sensory, other symptoms, and absent focal signs on assessment (p<0.05).

INTERPRETATION

Presenting features can discriminate childhood AIS from migraine. These differences inform decisions about urgency and type of neuroimaging in children presenting to the emergency department with brain attack symptoms.

WHAT THE PAPER ADDS

Weakness, seizures, ataxia, speech, or walking difficulties are more frequent in arterial ischaemic stroke (AIS). Vomiting, visual, or sensory disturbance and absent focal signs are more frequent in migraine. Identifying features of AIS and migraine guides neuroimaging in children with brain attack symptoms.

The current prevalence of asthma, allergic rhinitis, and eczema related symptoms in school-aged children in Costa Rica

OBJECTIVE

Asthma prevalence in Costa Rica is among the highest worldwide. We aimed to determine the prevalence of asthma among school-age children in the Central Highland Area of Costa Rica.

METHODS

Cross-sectional study using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was performed. Parents or guardians of children aged 6-13 years completed written questionnaires.

RESULTS

Total of 2817 school-aged children returned these questionnaires (74.1% return rate). The prevalence of asthma, rhinitis, and eczema was 21.9%, 42.6%, and 19.2%, respectively. The co-existence of the 3 diseases was seen in 22.6% of children with asthma. Boys had a slightly higher prevalence of these conditions, and younger children had higher prevalence of asthma and eczema, but lower prevalence of rhinitis than older children. The use of acetaminophen and antibiotics in the first 12 months of life showed a significant association with the prevalence of asthma, rhinitis, and eczema. Wheezing with exercise, dry cough at night, and ever rhinitis was highly associated with asthma symptoms in the last 12 months. In contrast, no association was found between children exposed to smoking at home. Frequent traffic next to the house was reported more frequently by the parents of children with asthma, although no significant association was found.

CONCLUSION

The prevalence of asthma showed a significant decrease compared to previous studies. However, there was an unexpected high prevalence of rhinitis. Exposure to acetaminophen and antibiotic during the first year of life was highly associated with asthma symptoms.

Accuracy and Reliability of Stroke Diagnosis in the Pediatric Emergency Department

BACKGROUND AND PURPOSE

Access to acute stroke interventions in the emergency department (ED) relies on correct clinical diagnosis. Our aims were to determine the accuracy and reliability of pediatric ED physician diagnosis of childhood stroke and other conditions presenting with brain attack symptoms.

METHODS

Prospective study of consecutive children aged 1 month to 18 years presenting to the ED from June 2009 to December 2010 with focal neurological deficits. Accuracy (sensitivity, specificity, and receiver operator characteristic curves [ROCs]) and interrater agreement (κ) were determined, between ED physician diagnoses, as recorded in the electronic hospital administrative software system, and final neurological diagnosis, after completion of diagnostic work-up.

RESULTS

Two-hundred eighty-seven children with 301 consecutive presentations were recruited. The most common final brain attack diagnoses included migraine in 84 children, first seizure in 48, Bell's palsy in 29, stroke in 21, and conversion disorders in 18 children. Sensitivity of ED physician stroke diagnosis was 62%, and specificity was 98% (ROC, 0.8). Inter-rater agreement for ED physician and final stroke diagnosis was substantial (κ=0.61). ED physician diagnostic accuracy and reliability was highest for Bell's palsy (ROC=0.98; κ=0.96), and lowest for central nervous system demyelination (ROC=0.5; κ=-0.01) and cerebellitis (ROC=0.50; κ=0.50).

CONCLUSIONS

ED physician diagnostic accuracy and reliability varies considerably across disorders presenting with brain attack symptoms. Clinical recognition tools are required to assist pediatric ED physicians with diagnosis of stroke and other serious neurological disorders.

Abstract WMP110: Differentiating Childhood Arterial Ischemic Stroke From Migraine in the Pediatric Emergency Department

Objective: Migraine, a typically benign disorder, is the most common stroke mimic in children presenting with brain attacks. We aimed to identify clinical features which discriminate childhood arterial ischaemic stroke (AIS) from migraine.

Methods: Fifty-five consecutive children with AIS, presenting to a tertiary pediatric emergency department (ED), prospectively/retrospectively recruited from 2003-2010, were compared to 84 children with migraine, prospectively recruited from 2009-2010.

Results: Health professional referral, (odds ratio (OR), 5.71, 95% confidence intervals 2.54-12.81), ambulance transport (OR 2.95, 1.45-5.97), high triage category assignment (OR 2.41, 1.06-5.49), sudden onset (OR 2.74, 1.18-6.39), symptoms of focal weakness (OR 6.96, 3.24-14.93), seizures (OR 7.44, 1.99-27.81), speech disturbance (OR 3.06, 1.48-6.32), and ataxia (OR 4.88, 1.63-14.65) were significantly associated with increased odds of AIS diagnosis. Signs of face (OR 155.37, 20.03-1205.33), arm (OR 15.58, 6.41-37.84), or leg weakness (OR 15.40, 5.75-41.27), inability to walk (OR 14.18, 3.07-65.41), dysarthria (OR 47.21, 6.07-367.13), dysphasia (OR 12.76, 1.52-106.97) and altered consciousness (OR 2.45, 1.03-5.85) were also significantly associated with increased odds of AIS diagnosis, In contrast, vomiting (OR 0.23, 0.10-0.53), visual symptoms (OR 0.24, 0.10-0.57), other symptoms (OR 0.06, 0.01-0.48) and absence of neurological signs on ED physician assessment (OR 0.05, 0.01-0.17) were associated with decreased odds of AIS diagnosis.

Conclusion: Differing presenting symptoms and signs allow discrimination of childhood AIS from migraine. These findings can inform decisions about urgency and type of diagnostic neuroimaging in the ED for children presenting with brain attack symptoms.

Abstract 173: Accuracy and Reliability of Brain Attack Diagnoses Including Stroke in the Pediatric Emergency Department

Objectives: Access to acute stroke interventions in the emergency department (ED) relies on correct clinical diagnosis. Our aims were to determine the accuracy and reliability of pediatric ED physician diagnosis of childhood stroke and other conditions presenting with brain attack symptoms.

Methods: Prospective study of consecutive children aged one month-18 years presenting to the ED from June 2009-December 2010 with focal neurological deficits. Accuracy (sensitivity, specificity, receiver operator characteristic curves (ROCs)), and inter-rater agreement (kappa (κ )) were determined, between ED physician diagnoses, as recorded in the electronic hospital administrative software system, and final neurological diagnosis, following completion of diagnostic work-up.

Results: Two-hundred-eighty seven children with 301 consecutive presentations were recruited. The most common final brain attack diagnoses included migraine in 84 children, first seizure in 48, Bell’s palsy in 29, stroke in 21, and conversion disorders in 18 children. Sensitivity of ED physician stroke diagnosis was 62% and specificity was 98% (ROC 0.8). Inter-rater agreement for ED physician and final stroke diagnosis was substantial (κ 0.61). ED physician diagnostic accuracy and reliability was highest for Bell’s palsy (ROC 0.98, κ 0.96), and lowest for CNS demyelination (ROC 0.5, κ -0.01) and cerebellitis (ROC 0.50, κ 0.50).

Conclusions: ED physician diagnostic accuracy and reliability varies considerably across disorders presenting with brain attack symptoms. Clinical recognition tools are required to assist pediatric ED physicians with diagnosis of stroke and other serious neurological disorders.

Differentiating Childhood Stroke From Mimics in the Emergency Department

BACKGROUND AND PURPOSE

Clinical identification of stroke in the pediatric emergency department is critical for improving access to hyperacute therapies. We identified key clinical features associated with childhood stroke or transient ischemic attack compared with mimics.

METHODS

Two hundred and eighty consecutive children presenting to the emergency department with mimics, prospectively recruited over 18 months from 2009 to 2010, were compared with 102 children with stroke or transient ischemic attack, prospectively/retrospectively recruited from 2003 to 2010.

RESULTS

Cerebrovascular diagnoses included arterial ischemic stroke (55), hemorrhagic stroke (37), and transient ischemic attack (10). Mimic diagnoses included migraine (84), seizures (46), Bell's palsy (29), and conversion disorders (18). Being well in the week before presentation (odds ratio [OR] 5.76, 95% confidence interval [CI] 2.25-14.79), face weakness (OR 2.94, 95% CI 1.19-7.28), arm weakness (OR 8.66, 95% CI, 2.50-30.02), and inability to walk (OR 3.38, 95% CI 1.54-7.42) were independently associated with increased odds of stroke diagnosis. Other symptoms were independently associated with decreased odds of stroke diagnosis (OR 0.28, 95% CI 0.10-0.77). Associations were not observed between seizures or loss of consciousness. Factors associated with stroke differed by arterial and hemorrhagic subtypes.

CONCLUSIONS

Being well in the week before presentation, inability to walk, face and arm weakness are associated with increased odds of stroke. The lack of positive or negative association between stroke and seizures or loss of consciousness is an important difference to adults. Pediatric stroke pathways and bedside tools need to factor in differences between children and adults and between stroke subtypes.

Abstract T MP61: Diagnostic Accuracy of Adult Bedside Stroke Recognition Tools in Childhood Stroke

Objective: Bedside stroke recognition tools improve diagnostic accuracy in adult stroke. Our aim was to assess the diagnostic utility of the CPSS and ROSIER tools in children presenting to the emergency department (ED) with brain attack symptoms.

Methods: The Cincinnati Prehospital Stroke Scale (CPSS ) and the Recognition of Stroke in the Emergency Room (ROSIER) tool were retrospectively applied to 101 consecutive children with stroke, presenting from 2003-2010, and 279 children with mimics, presenting to the ED from 2009-2010. A positive CPSS was defined as ≥1 positive sign (face or arm weakness, speech disturbance). A positive ROSIER was defined as a score of ≥1. Diagnostic accuracy of the tools in determining the patients’ true status were estimated for arterial (AIS), hemorrhagic (HS) and combined stroke subtypes versus mimics.

Results: The CPSS and ROSIER tools correctly discriminated combined stroke subtypes from mimics (diagnostic odds ratio (DOR) 5.6 and 4.7 respectively) and AIS from mimics (DOR 15.1 and 13.4 respectively) but not HS from mimics (DOR 1.2 for both tools). CPSS and ROSIER accuracy were fair for AIS versus mimics (ROC 0.79 and 0.77 respectively), fair to poor for combined stroke subtypes versus mimics (ROC 0.70 and 0.68 respectively) and failed for HS versus mimics (ROC 0.51 and 0.52 respectively). Reasons for limited accuracy include different spectrum of mimics, lower overall prevalence, higher proportion of HS subtype and common seizure occurrence in childhood stroke.

Conclusions: Adult stroke recognition tools correctly discriminate combined stroke types and AIS subtype from mimics but their limited accuracy suggest further modifications are required to improve diagnostic utility for identification of childhood stroke in the ED.

Abstract 37: Pediatric Brain Attacks: Differentiating Between Stroke and Mimics in the Emergency Room

Objective: Timely recognition of stroke in the pediatric emergency room (ER) is critical to improving access to hyper-acute therapies. We aimed to identify key clinical features which discriminate between stroke and non-stroke brain attacks (mimics).

Methods: Two-hundred and eighty consecutive children presenting to the ER with non-stroke brain attacks, prospectively recruited over 18 months in 2009-2010, were compared to 104 children with stroke, prospectively/retrospectively recruited from 2003-2010. Brain attack was defined as acute onset focal brain dysfunction with ongoing symptoms or signs on arrival to the ER. Exclusion criteria included known epilepsy, hydrocephalus, head trauma and isolated headache.

Results: Stroke diagnoses included arterial ischemic stroke (AIS) (55), hemorrhagic stroke (HS) (37), TIA (10) and sinovenous thrombosis (2). The most common mimic diagnoses included migraine (87), first seizure (46), Bell’s palsy (29) and conversion disorder (18). Children with stroke were more likely to have sudden onset of symptoms (85% vs. 71%), arrive by ambulance (63% vs. 33%) and receive higher triage category (43% vs. 23%) than mimics (p<0.001 all variables). Symptoms with good discriminatory value (stroke vs. mimic) included focal weakness (58% vs. 34%), altered consciousness (31% vs. 19%) and speech disturbance (36% vs. 16%) (p<0.001 all variables). Signs with good discriminatory value included focal weakness of the face (45% vs. 14%), arm (47% vs. 13%) or leg (38% vs. 15%), dysarthria (22% vs. 5%), dysphasia (11% vs 3%) and altered consciousness (43% vs. 23%) (p<0.001 all variables). Absence of focal neurological signs (20% stroke vs 35% mimic) on examination predicted mimic (p=0.005).

Conclusions: Focal weakness and speech disturbance predict stroke diagnosis in children with brain attack symptoms, findings which are similar to adults. These findings will inform the development of pediatric bedside stroke recognition tools to improve rapid recognition of stroke by emergency physicians.

Can the FAST and ROSIER adult stroke recognition tools be applied to confirmed childhood arterial ischemic stroke?

Background

Stroke recognition tools have been shown to improve diagnostic accuracy in adults. Development of a similar tool in children is needed to reduce lag time to diagnosis. A critical first step is to determine whether adult stoke scales can be applied in childhood stroke.

Our objective was to assess the applicability of adult stroke scales in childhood arterial ischemic stroke (AIS)

Methods

Children aged 1 month to < 18 years with radiologically confirmed acute AIS who presented to a tertiary emergency department (ED) (2003 to 2008) were identified retrospectively. Signs, symptoms, risk factors and initial management were extracted. Two adult stroke recognition tools; ROSIER (Recognition of Stroke in the Emergency Room) and FAST (Face Arm Speech Test) scales were applied retrospectively to all patients to determine test sensitivity.

Results

47 children with AIS were identified. 34 had anterior, 12 had posterior and 1 child had anterior and posterior circulation infarcts. Median age was 9 years and 51% were male. Median time from symptom onset to ED presentation was 21 hours but one third of children presented within 6 hours. The most common presenting stroke symptoms were arm (63%), face (62%), leg weakness (57%), speech disturbance (46%) and headache (46%). The most common signs were arm (61%), face (70%) or leg weakness (57%) and dysarthria (34%). 36 (78%) of children had at least one positive variable on FAST and 38 (81%) had a positive score of ≥1 on the ROSIER scale. Positive scores were less likely in children with posterior circulation stroke.

Conclusion

The presenting features of pediatric stroke appear similar to adult strokes. Two adult stroke recognition tools have fair to good sensitivity in radiologically confirmed childhood AIS but require further development and modification. Specificity of the tools also needs to be determined in a prospective cohort of children with stroke and non-stroke brain attacks.
