BACKGROUND The diagnosis of pneumonia in children is challenging, given the wide overlap of many of the symptoms and physical examination findings with other common respiratory illnesses. We sought to derive and validate the novel Pneumonia Risk Score (PRS), a clinical tool utilizing signs and symptoms available to clinicians to determine a child's risk of radiographic pneumonia. METHODS We prospectively enrolled children 3 months to 18 years in whom a chest radiograph (CXR) was obtained in the emergency department to evaluate for pneumonia. Before CXR, we collected information regarding symptoms, physical examination findings, and the physician-estimated probability of radiographic pneumonia. Logistic regression was used to predict the presence of radiographic pneumonia, and the PRS was validated in a distinct cohort of children with suspected pneumonia. RESULTS Among 1181 children included in the study, 206 (17%) had radiographic pneumonia. The PRS included age in years, triage oxygen saturation, presence of fever, presence of rales, and presence of wheeze. The area under the curve (AUC) of the PRS was 0.71 (95% confidence interval [CI]: 0.68-0.75), while the AUC of clinician judgment was 0.61 (95% CI: 0.56-0.66) (P < 0.001). Among 2132 children included in the validation cohort, the PRS demonstrated an AUC of 0.69 (95% CI: 0.65-0.73). CONCLUSIONS In children with suspected pneumonia, the PRS is superior to clinician judgment in predicting the presence of radiographic pneumonia. Use of the PRS may help efforts to support the judicious use of antibiotics and chest radiography among children with suspected pneumonia.

BACKGROUND Illness complications are condition-specific adverse outcomes. Detecting complications of pediatric illness in administrative data would facilitate widespread quality measurement, however the accuracy of such detection is unclear. METHODS We conducted a cross-sectional study of patients visiting a large pediatric emergency department. We analyzed those RESULTS We analyzed 1534 encounters. PPVs and NPVs for complications were >80% for 8 of 14 conditions: appendicitis, bacterial meningitis, intussusception, mastoiditis, myocarditis, orbital cellulitis, sepsis, and testicular torsion. Lower PPVs for complications were observed for DKA (57%), empyema (53%), encephalitis (78%), ovarian torsion (21%), and septic arthritis (64%). A lower NPV was observed in stroke (68%). The κ between reviewers was 0.88. CONCLUSIONS An automated method to measure complications by using administrative data can detect complications in appendicitis, bacterial meningitis, intussusception, mastoiditis, myocarditis, orbital cellulitis, sepsis, and testicular torsion. For DKA, empyema, encephalitis, ovarian torsion, septic arthritis, and stroke, the tool may be used to screen for complicated cases that may subsequently undergo manual review.

Background Secondary sonographic findings of appendicitis can aid image analysis and support diagnosis with and without visualization of an appendix. Objective We sought to determine if age affected the test performance of secondary findings for pediatric appendicitis. Materials and methods We performed a medical record review of emergency department patients younger than 19 years of age who had a sonogram for suspected appendicitis. Our primary patient outcome was appendicitis, as determined by pathology or by image-confirmed perforation/abscess. Our primary analysis was test performance of secondary sonographic findings as recorded by sonographers on the final diagnosis of appendicitis stratified by age (

BACKGROUND AND OBJECTIVES Several studies have revealed the success of nonoperative management (NOM) of uncomplicated appendicitis in children. Large studies of current NOM utilization and its outcomes in children are lacking. METHODS We queried the Pediatric Health Information System database to identify children RESULTS We identified 117 705 children with appendicitis over the 9-year study period. Of the 73 544 children with nonperforated appendicitis, 10 394 (14.1%) underwent NOM. The odds of NOM significantly increased (odds ratio 1.10 per study quarter, 95% confidence interval [CI] 1.05–1.15). The 1-year and 5-year failure rates were 18.6% and 23.3%, respectively. Children who experienced failure of NOM had higher rates of perforation at the time of failure than did the general cohort at the time of initial presentation (45.7% vs 37.5%, P < .001). Patients undergoing NOM had higher rates of subsequent related emergency department visits (8.0% vs 5.1%, P < .001) and hospitalizations (4.2% vs 1.4%, P < .001) over a 12-month follow-up period. CONCLUSIONS NOM of nonperforated appendicitis in children is increasing. Although the majority of children who undergo NOM remain recurrence-free years later, they carry a substantial risk of perforation at the time of recurrence and may experience a higher rate of postoperative complications than children undergoing an immediate appendectomy.

OBJECTIVE We aimed to characterize recent trends in bronchiolitis at US children’s hospitals and to compare severity of illness in bronchiolitis in the most recent year to the previous seasonal epidemics. METHODS This is a cross-sectional study of visits for bronchiolitis in infants RESULTS The study included 389 411 emergency visits for bronchiolitis. Median age of infants with bronchiolitis was higher in October 2020 to September 2021 compared to previous epidemics (8 and 6 months, respectively, P < .001) The odds of hospitalization, ICU admission, invasive mechanical ventilation, and noninvasive ventilation did not differ in October 2020 to September 2021 compared to previous epidemics from October 2016 to September 2020 (all P > .05 for unadjusted models and models adjusted for age). Seasonality varied significantly among these 2 periods (P < .001). CONCLUSIONS Although the seasonality of bronchiolitis differed in October 2020 to September 2021, severity of illness in infants with bronchiolitis was consistent with previous epidemics.

Objective Diabetic ketoacidosis (DKA) is a common emergency department presentation of both new-onset and established diabetes mellitus (DM). β-Hydroxybutyrate (BOHB) provides a direct measure of the pathophysiologic derangement in DKA as compared with the nonspecific measurements of blood pH and bicarbonate. Our objective was to characterize the relationship between BOHB and DKA. Methods This is a cross-sectional retrospective study of pediatric patients with DM presenting to an urban pediatric emergency department between January 1, 2016, and September 30, 2018. Analyses were performed on each patient's initial, simultaneous BOHB and pH. Diagnostic test characteristics of BOHB were calculated, and logistic regression was performed to investigate the effects of age and other key clinical factors. Results Among 594 patients with DM, with median age of 12.3 years (interquartile range, 8.7-15.9 years), 176 (29.6%) presented with DKA. The inclusion of age, transfer status, and new-onset in the statistical model did not improve the prediction of DKA beyond BOHB alone. β-Hydroxybutyrate demonstrated strong discrimination for DKA, with an area under the curve of 0.95 (95% confidence interval, 0.93-0.97). A BOHB value of 5.3 mmol/L predicted DKA with optimal accuracy (90.6% of patients were correctly classified). The sensitivity, specificity, and positive and negative predictive values of this cut point were 76.7% (95% confidence interval, 69.8%-82.7%), 96.4% (94.2%-98.0%), 90.0% (84.0%-94.3%), and 90.8% (87.7%-93.3%), respectively. Conclusions β-Hydroxybutyrate accurately predicts DKA in children and adolescents. More importantly, because plasma BOHB is the ideal biochemical marker of DKA, BOHB may provide a more optimal definition of DKA for management decisions and treatment targets.

OBJECTIVES We examined trends in resource use for infants undergoing emergency department evaluation for serious bacterial infection, including lumbar puncture (LP), antibiotic administration, hospitalization, and procalcitonin testing, as well as the association between procalcitonin testing and LP, administration of parenteral antibiotics, and hospitalization. METHODS We performed a cross-sectional study of infants aged 0 to 60 days who underwent emergency department evaluation for serious bacterial infection with blood and urine cultures from 2010 to 2019 in 27 hospitals in the Pediatric Health Information System. We examined temporal trends in LP, antibiotic administration, hospitalization, and procalcitonin testing from 2010 to 2019. We also estimated multivariable logistic regression models for 2017–2019, adjusted for demographic factors and stratified by age ( RESULTS We studied 106 547 index visits. From 2010 to 2019, rates of LP, antibiotic administration, and hospitalization decreased more for infants aged 29 to 60 days compared with infants aged 0 to 28 days (annual decrease in odds of LP, antibiotics administration, and hospitalization: 0 to 28 days: 5%, 5%, and 3%, respectively; 29–60 days: 15%, 12%, and 7%, respectively). Procalcitonin testing increased significantly each calendar year (odds ratio per calendar year 2.19; 95% confidence interval 1.82–2.62), with the majority (91.1%) performed during 2017–2019. From 2017 to 2019, there was no association between hospital-level procalcitonin testing and any outcome studied (all P values > .05). CONCLUSIONS Rates of LP, antibiotic administration, and hospitalization decreased significantly for infants 29 to 60 days during 2010–2019. Although procalcitonin testing increased during 2017–2019, we found no association with hospital-level procalcitonin testing and patterns of resource use.

To investigate the rates of radiographic pneumonia and clinical outcomes of children with suspected pneumonia and subcentimeter, subpleural consolidations on point-of-care lung ultrasound.We enrolled a prospective convenience sample of children aged 6 months to 18 years undergoing chest radiography (CXR) for pneumonia evaluation in a single tertiary-care pediatric emergency department. Point-of-care lung ultrasound was performed by an emergency medicine physician with subsequent expert review. We determined rates of radiographic pneumonia and clinical outcomes in the children with subcentimeter, subpleural consolidations, stratified by the presence of larger (1 cm) sonographic consolidations. The children were followed prospectively for 2 weeks to identify a delayed diagnosis of pneumonia.A total of 188 patients, with a median age of 5.8 years (IQR, 3.5-11.0 years), were evaluated. Of these patients, 62 (33%) had subcentimeter, subpleural consolidations on lung ultrasound, and 23 (37%) also had larger (1 cm) consolidations. Patients with subcentimeter, subpleural consolidations and larger consolidations had the highest rates of definite radiographic pneumonia (61%), compared with 21% among children with isolated subcentimeter, subpleural consolidations. Overall, 23 children with isolated subcentimeter, subpleural consolidations (59%) had no evidence of pneumonia on CXR. Among 16 children with isolated subcentimeter, subpleural consolidations and not treated with antibiotics, none had a subsequent pneumonia diagnosis within the 2-week follow-up period.Children with subcentimeter, subpleural consolidations often had radiographic pneumonia; however, this occurred most frequently when subcentimeter, subpleural consolidations were identified in combination with larger consolidations. Isolated subcentimeter, subpleural consolidations in the absence of larger consolidations should not be viewed as synonymous with pneumonia; CXR may provide adjunctive information in these cases.

BACKGROUND AND OBJECTIVESThere are no effective interventions to prevent hospital admissions in infants with bronchiolitis. The American Academy of Pediatrics recommends against routine bronchodilator use for bronchiolitis. The objective of this study was to characterize trends in and outcomes associated with the use of bronchodilators for bronchiolitis.METHODSThis is a multicenter retrospective study of infants RESULTSA total of 446 696 ED visits of infants with bronchiolitis were included. Bronchodilator use, hospital admissions, and ED return visits decreased between 2010 and 2018 (all P < .001). ICU admissions and invasive and noninvasive ventilation increased over the study period (all P < .001). Hospital-level early bronchodilator use (hospitals with high versus low use) was not associated with differences in patient-level hospital admissions, ICU admissions, ED return visits, noninvasive ventilation, or invasive ventilation (all P > .05).CONCLUSIONSIn a large study of infants at children’s hospitals, bronchodilator therapy decreased significantly from 2010 to 2018. Hospital-level early bronchodilator use was not associated with a reduction in any outcomes. This study supports the current American Academy of Pediatrics recommendation to limit routine use of bronchodilators in infants with bronchiolitis.

Pediatric visits to the Emergency Department (ED) for concussion are common and increasing. ED clinicians evaluating children with concussion should first ensure the absence of more serious injuries requiring immediate intervention, such as intracranial hemorrhage or cervical spine injury. In the ED setting, signs and symptoms of concussion are sometime subtle and often overlooked. A thorough physical exam is warranted but may be normal. Imaging and laboratory studies have no role in concussion diagnosis and should be reserved for cases where an injury requiring immediate intervention is suspected. Symptom management may include avoiding symptom-triggers (such as bright lights triggering headaches) and/or specific treatments such as nonsteroidal anti-inflammatories or antiemetics. Discharge instructions should include a recommendation for a brief period of rest, followed by outpatient management for return-to-activity decisions in conjunction with a primary care provider.

As both fever and pneumonia can be associated with tachypnea, we investigated the relationship between body temperature and respiratory rate (RR) in young children and whether temperature-adjusted RR enhances the prediction of pneumonia.In this retrospective cross-sectional analysis of 91,429 children5 years of age presenting to an urban pediatric emergency department, the relationship between triage RR and temperature was analyzed using regression analysis. We assessed the predictive value of temperature-adjusted RR for the diagnosis of pneumonia; diagnostic performance was evaluated for continuous RR as well as World Health Organization (WHO) age-based RR thresholds.The mean RR increased 2.6 breaths/minute for each 1°C increase in temperature. Interpatient variability was comparatively large; at any temperature, the interquartile range (75th percentile minus 25th percentile) varied from 4 to 16 breaths/minute. For predicting pneumonia, temperature- and age-adjusted RR was superior to age-adjusted RR: area under the curve (AUC) = 0.76 (95% confidence interval [CI], 0.75-0.78) versus AUC = 0.73 (95% CI, 0.72-0.75), respectively. Using WHO RR criteria, temperature-adjusted RR improved diagnostic discrimination, as the AUC increased from 0.58 (95% CI, 0.57-0.59) to 0.72 (95% CI, 0.70-0.73).The effects of temperature on respiratory rate are modest, with a mean increase of 2.6 breaths/minute for each 1°C rise in temperature. Despite considerable interpatient variability in respiratory rates by temperature, temperature adjustment improves the diagnostic value of respiratory rate for pneumonia.

Objectives The aim of this study was to determine the reasons for pediatric emergency department (ED) transfers and the professional characteristics of transferring providers. Methods We performed a multicenter, cross-sectional survey of ED medical providers transferring patients younger than 18 years to 1 of 4 tertiary care children's hospitals. Referring providers completed surveys detailing the primary reasons for transfer and their medical training. Results The survey data were collected for 25 months, during which 641 medical providers completed 890 surveys, with an overall response rate of 25%. Most pediatric patients were seen by physicians (89.4%) with predominantly general emergency medicine training (64.2%). The median age of patients seen was 5.6 years. The 3 most common diagnoses were closed extremity fracture (12.2%), appendicitis (11.6%), and pneumonia (3.7%). The 3 most common reasons for transfer were need for medical/surgical subspecialist consultation (62.6%), admission to the inpatient unit (17.1%), and admission to the intensive care unit (6.5%). When asked about the need for supportive pediatric services, referring providers ranked pediatric subspecialty and pediatric inpatient unit availability as the highest. Conclusions Most pediatric interfacility ED transfers are referred by general emergency medicine physicians who often transfer for inpatient admission or subspecialty consultation. Understanding the needs of the community-based ED providers is an important step to forming more collaborative efforts for regionalized pediatric emergency care.

Starting in 2022, the American Board of Pediatrics will launch the Maintenance of Certification Assessment for Pediatrics: Pediatric Emergency Medicine (MOCA-Peds: PEM) longitudinal assessment, which will provide an at-home alternative to the point-in-time examination. This longitudinal assessment will help engage PEM physicians participating in continuing certification in a more flexible and continuous lifelong, self-directed learning process while still providing a summative assessment of their knowledge. This commentary provides background information on MOCA-Peds and an introduction to MOCA-Peds: PEM and how it gives the PEM physician another option to participate in continuing certification.

Objective To compare the clinical presentation of intussusception among children younger and older than 24 months of age. Design/methods We performed a retrospective cross-sectional cohort study of children treated in the emergency department, aged 1 month to 6 years, who had an abdominal ultrasound to evaluate for intussusception over a 5-year period. After stratifying by an age cut-point of 24 months, univariate and multivariate analyses were performed. Results One thousand two hundred fifty-eight cases of suspected intussusception were studied; median age was 1.7 years (interquartile range, 0.8, 2.9 years), and 37% were female. Intussusception was identified in 176 children (14%); 153 (87%) were ileocolic, and 23 were ileoileal. Abdominal pain (odds ratio, 4.0; 95% confidence interval [CI], 1.5-10.5), emesis (OR, 3.5; 95% CI, 1.8-6.7), bilious emesis (OR, 2.9; 95% CI, 1.5-5.7), lethargy (OR, 2.3; 95% CI, 1.3-5.7), rectal bleeding (OR, 2.8; 95% CI, 1.4-5.7), and irritability (OR, 0.4; 95% CI, 0.2-0.8) were found to be predictors in those younger than 24 months. In children older than 24 months, male sex was the only predictor identified (OR, 2.0; 95% CI, 1.1-3.7). In cases where abdominal radiographs were obtained (n = 1212), any abnormality on abdominal radiograph was found to be predictive in both age groups (OR, 7.8; 95% CI, 3.8-25.7; and OR, 3.1; 95% CI, 1.8-5.2, respectively). Conclusions Intussusception presents differently in children younger than 24 months compared with older children. "Traditional" clinical predictors of intussusception should be interpreted with caution when assessing children older than 2 years.

Objectives The aim of this study was to describe the resource utilization for children with common pediatric conditions treated in academic and nonacademic emergency departments (EDs). Methods We performed a retrospective, cross-sectional descriptive study using the National Hospital Ambulatory Medical Care Survey Data from 1995 to 2010 including children less than 18 years old with a diagnosis of asthma, bronchiolitis, croup, gastroenteritis, fever, febrile seizure, or afebrile seizure. Academic EDs (A-ED) were those with greater than 25% of patients seen by a trainee. For each condition, we reported the proportion of testing, medications, and disposition between A-ED and nonacademic EDs (NA-ED). Results From 1995 to 2010, approximately 450,000,000 estimated pediatric visits are represented by the survey based on 122,811 actual visits. For most common conditions, testing and disposition were comparable; however, some variation was noted. Among patients with bronchiolitis, a higher proportion of patients was admitted and had radiographs in NA-EDs (18% vs 10% and 56% vs 45%, respectively). For children with croup, radiographs were performed more often at NA-EDs (27% vs 6%). Among those with febrile seizures, more lumbar punctures were performed in NA-EDs (14% vs 0%). In children with afebrile seizures, more head computed tomography scans were obtained at NA-EDs (34% vs 21%). Conclusion Among pediatric patients with croup, bronchiolitis, and febrile and afebrile seizure, higher resource utilization and admissions were observed in NA-EDs. These preliminary findings from a national survey require a more detailed investigation into the variation in care between A-ED and NA-ED settings.

OBJECTIVE To estimate rates of critical medical and neurosurgical interventions and resource utilization for children with traumatic intracranial hemorrhage (ICH). METHODS This was a retrospective study of children younger than 18 years hospitalized in 1 of 35 hospitals in the Pediatric Health Information System from 2009 to 2019 for ICH. We defined critical intervention as a critical medical (hyperosmotic agents and intubation) or neurosurgical intervention. We determined rates of critical interventions, intensive care unit (ICU) admission, and repeat neuroimaging. We used hierarchical logistic regression to identify high-level factors associated with undergoing critical interventions, controlling for hospital-level effects. RESULTS There were 12,714 children with ICH included in the study. Median (interquartile range) age was 4.3 (0.7-11.0) years. Twelve percent (n = 1470) of children underwent a critical clinical intervention. Critical medical interventions occurred in 10% (n = 1219), and neurosurgical interventions occurred in 3% (n = 419). Intensive care unit admission occurred in 44% (n = 5565), whereas repeat neuroimaging occurred in 40% (n = 5072). Among ICU patients, 79% (n = 4366) did not undergo a critical intervention. Of the 11,244 children with no critical interventions, 39% (n = 4366) underwent ICU admission, and 37% (n = 4099) repeat neuroimaging. After controlling for hospital, children with isolated subdural (P = 0.013) and isolated subarachnoid (P < 0.001) hemorrhage were less likely to receive critical interventions. CONCLUSIONS Critical medical interventions occurred in 10% of children with ICH, and neurosurgical interventions occurred in 3%. Intensive care unit admission and repeat neuroimaging are common, even among those who did not undergo critical interventions. Selective utilization of ICU admission and repeat neuroimaging in children who are at low risk of requiring critical interventions could improve overall quality of care and decrease unnecessary resource utilization.

Proficient physician performance is crucial to high-quality health care. Physicians must acquire and apply new knowledge and skills throughout their careers. Successful physician performance improvement requires leadership with vision and a strategic plan, engagement of front line providers, resources and support to improve, and feedback and communication that facilitates a culture of learning and improvement. A fluid and balanced performance dashboard, aligned with local improvement efforts, can inform individuals and groups of physicians, ensure the trust of other stakeholders, and improve the quality of patient care. We propose a framework for the development of a performance program for pediatric emergency physicians and share the experience of development and use of the program at a single tertiary care site.

The approach to febrile young infants remains challenging. This review serves as an update on the care of febrile infants less than 90 days of age with a focus on the changing epidemiology of serious bacterial infection (SBI), refinement of management strategies based on biomarkers, and the development of novel diagnostics.There is high variability in the emergency department management of febrile young infants without significant differences in outcomes. C-reactive protein (CRP) and procalcitonin have emerged as valuable risk-stratification tests to identify high-risk infants. When interpreting automated urinalyses for suspected urinary tract infection (UTI), urine concentration influences the diagnostic value of pyuria. Novel diagnostics including RNA biosignatures and protein signatures show promise in better identifying young febrile infants at risk of serious infection.The majority of febrile infants with an SBI will have a UTI but the diagnosis of invasive bacterial infection in infants continues to be challenging. The use of procalcitonin and CRP as biomarkers in prediction algorithms facilitates identification of low-risk infants.

Opportunities to learn advanced airway management skills on pediatric patients in the emergency department are limited. Current strategies have focused largely on traditional didactics coupled with procedural skills training using simulation. However, these approaches are limited in their exposure to anatomic variation and realism. Here, we describe the development and assessment of an advanced airway curriculum that integrates videolaryngoscopic recordings obtained during actual patient intubations into a series of interactive educational sessions. Trainees and attending physicians were surveyed anonymously to assess the impact of participation in the curriculum. A mixed methods approach to statistical analysis was used. Rating questions were used to evaluate the relative impact of this approach over other traditional strategies and recurrent themes within open-ended questions were identified. Participants reported this to be a highly effective means of learning about pediatric laryngoscopy and endotracheal intubation and regarded it more highly than other traditional educational approaches. Identified benefits included repetitive exposure, approaches to laryngoscopy, the realism of teaching using real and varied anatomy, and the opportunities to identify and troubleshoot difficulty in a learning environment. An advanced pediatric airway curriculum that integrates intubation videos obtained during videolaryngoscopy was highly regarded by pediatric emergency medicine providers. Content emphasis can be shifted to meet the needs of pediatric emergency medicine providers with all levels of skill and experience.

Concerns about radiation exposure have led to a decrease in the use of computed tomography in suspected appendicitis, with increased reliance on ultrasound. Children with suspected appendicitis should be risk stratified using a combination of clinical signs and symptoms, white blood cell count, and ultrasound in order to guide further evaluation and management. Magnetic resonance imaging is a promising imaging modality but remains costly. Ongoing research is evaluating the role of nonoperative management in children with confirmed appendicitis.

Pediatric emergency care research suffers from a generalizability problem. Such research in the United States largely relies on data collected from within academic medical centers or large health systems with the infrastructure to conduct and publish clinical research. Such research also includes studies ranging from trials of fluid infusion rates for diabetic ketoacidosis1 from the Pediatric Emergency Care Applied Research Network to retrospective cohort studies defining the incidence of herpes simplex virus by week of life.2 This research is extremely valuable because it informs how to distribute limited health care resources and where to focus efforts to improve care. However, academic and large health systems are a narrow lens through which to view care because 90% of children do not visit academic pediatric emergency departments (EDs) but rather visit community general EDs.3 Children who visit academic EDs differ from the larger population of children demographically, especially related to their access to, need for, and receipt of acute care. Because of these differences, epidemiological insights cannot always be generalized beyond the populations that academic centers serve. Large, population-based, administrative databases offer 1 solution to this problem. Administrative data are collected in the course of routine clinical operations and include claims, which are billing records. These databases do not typically contain clinical information and instead contain demographics, diagnoses, procedures, and billing information, such as charges. They therefore represent a blurrier but wider field of view than the narrow lens of academia-based investigation, thereby allowing more complete insight into diseases and outcomes. Furthermore, these databases eliminate the selection bias introduced by studying only children who present to academic hospitals, which often outweighs the advantages of prospective data collection. The main advantages of administrative data …

To define and measure complications across a broad set of acute pediatric conditions in emergency departments using administrative data, and to assess the validity of these definitions by comparing resource utilization between children with and without complications.Using local consensus, we predefined complications for 16 acute conditions including appendicitis, diabetic ketoacidosis, ovarian torsion, stroke, testicular torsion, and 11 others. We studied patients under age 18 years using 3 data years from the Healthcare Cost and Utilization Project Statewide Databases of Maryland and New York. We measured complications by condition. Resource utilization was compared between patients with and without complications, including hospital length of stay, and charges.We analyzed 27 087 emergency department visits for a serious condition. The most common was appendicitis (n = 16 794), with 24.3% of cases complicated by 1 or more of perforation (24.1%), abscess drainage (2.8%), bowel resection (0.3%), or sepsis (0.9%). Sepsis had the highest mortality (5.0%). Children with complications had higher resource utilization: condition-specific length of stay was longer when complications were present, except ovarian and testicular torsion. Hospital charges were higher among children with complications (P .05) for 15 of 16 conditions, with a difference in medians from $3108 (testicular torsion) to $13 7694 (stroke).Clinically meaningful complications were measurable and were associated with increased resource utilization. Complication rates determined using administrative data may be used to compare outcomes and improve healthcare delivery for children.

OBJECTIVES:Unlike community-acquired pneumonia (CAP), there is a paucity of data characterizing the patient demographics and hospitalization characteristics of children with aspiration pneumonia. We used a large national database of US children’s hospitals to assess the patient and hospitalization characteristics associated with aspiration pneumonia and compared these characteristics to patients with CAP.METHODS:We identified children hospitalized with a diagnosis of aspiration pneumonia or CAP at 47 hospitals included in the Pediatric Health Information System between 2009 and 2014. We evaluated whether differences exist in patient characteristics (median age and proportion of patients with a complex chronic condition), and hospital characteristics (length of stay, ICU admission, cost, and 30-day readmission rate) between children with aspiration pneumonia and CAP. Lastly, we assessed whether seasonal variability exists within these 2 conditions.RESULTS:Over the 6-year study period, there were 12 097 children hospitalized with aspiration pneumonia, and 121 489 with CAP. Compared with children with CAP, children with aspiration pneumonia were slightly younger and more likely to have an associated complex chronic condition. Those with aspiration pneumonia had longer hospitalizations, higher rates of ICU admission, and higher 30-day readmission rates. Additionally, the median cost for hospitalization was 2.4 times higher for children with aspiration pneumonia than for children with CAP. More seasonal variation was observed for CAP compared with aspiration pneumonia hospitalizations.CONCLUSIONS:Aspiration pneumonia preferentially affects children with medical complexity and, as such, accounts for longer and more costly hospitalizations and higher rates of ICU admission and readmission rates.

The optimal staffing model for emergency departments (EDs) is not known. Improving staffing could lead to more timely, efficient, and effective care. We created a model of staffing to identify times of staffing limitation by provider type.We analyzed data from an academic pediatric ED with 60,000 visits per year. Each 10-minute interval from January 1, 2011, through December 31, 2012, was categorized as nonlimited (no staffing limitation), space limited (≥2 patients in the waiting room with wait times30 minutes and ≥ 80% ED bed occupancy), nurse limited (≥2 patients in the waiting room with wait times30 min and80% ED bed occupancy), or physician limited (≥2 patients in examination rooms who have waited30 minutes for a physician) using computer modeling. We calculated the percentage of time each type of limitation was in effect and the median lengths of stay for patients presenting during times of each category of limitation.The ED was space limited 5.0% of the time, nurse limited 16.1% of the time, and physician limited 0.1% of the time. In nonlimited times, length of stay was 201 minutes (interquartile range, 128-301), whereas patients presenting during space-limited, nurse-limited, and physician-limited times had statistically significantly higher LOS of 265 (187-360), 244 (169-337), and 247 (174-334) minutes, respectively.Times identified as space and staffing limited were associated with longer LOS. This computer model could be used to rapidly identify targeted staffing needs and then measure the effect of modifying staffing.

Objectives: Biomarkers that can measure illness severity and predict the risk of delayed recovery may be useful in guiding pediatric septic shock. Amino-terminal pro-B-type natriuretic peptide has not been assessed in pediatric septic patients at the time of presentation to the emergency department prior to any interventions. The primary aim was to assess if emergency department amino-terminal pro-B-type natriuretic peptide is associated with worse outcomes and severity of illness. Design: Prospective observational pilot study. Settings: Tertiary free-standing children’s hospital. Patients: Children 0–17 years old with a diagnosis of septic shock were enrolled. Patients with preexisting cardiac and renal dysfunction were excluded. Interventions: None. Measurements and Main Results: Amino-terminal pro-B-type natriuretic peptide analysis was performed on samples obtained in the emergency department prior to any intervention. The association between biomarkers and clinical outcomes and illness severity using Pediatric RISk of Mortality 3 were assessed. Eighty-two patients with septic shock underwent analysis. The median (interquartile range) amino-terminal pro-B-type natriuretic peptide levels was 394 pg/mL (102–1,392 pg/mL). Each decile change increase in amino-terminal pro-B-type natriuretic peptide was associated with a change in ICU length of stay by 8.7%, (95% CI, 2.4–15.5), hospital length of stay by 5.7% (95% CI, 0.4–11.2), organ dysfunction by 5.1% (95% CI, 1.8–8.5), a higher inotropic score at 12, 24, and 36 hours, and longer time requiring vasoactive agents. There was a significant correlation between baseline amino-terminal pro-B-type natriuretic peptide and the Pediatric RISk of Mortality 3 score (Spearman rho = 0.247; p = 0.029). Conclusions: This pilot study shows an association between emergency department amino-terminal pro-B-type natriuretic peptide on presentation and worse septic shock outcomes and amino-terminal pro-B-type natriuretic peptide levels correlates with an ICU severity score.

Vascular endothelial growth factor (VEGF) and its receptor, soluble fms-like tyrosine kinase (sFLT), are biomarkers of endothelial activation. Vascular endothelial growth factor and sFLT have been associated with sepsis severity among adults, but pediatric data are lacking. The goal of this study was to assess VEGF and sFLT as predictors of outcome for children with sepsis. METHODS Biomarkers measured for each patient at time of presentation to the emergency department were compared in children with septic shock versus children with sepsis without shock. For children with septic shock, the associations between biomarker levels and clinical outcome measures, including intensive care unit and hospital length of stay, vasoactive inotrope score, and measures of organ dysfunction, were assessed. RESULTS Soluble fms-like tyrosine kinase and VEGF were elevated in children with septic shock (n = 73) compared with those with sepsis (n = 93). Elevated sFLT but not VEGF was associated with longer intensive care unit length of stay (P = 0.003), longer time requiring vasoactive agents (P < 0.001), higher maximum vasoactive inotrope score (P < 0.001), and higher maximum pediatric logistic organ dysfunction score (P < 0.001). CONCLUSIONS Vascular endothelial growth factor and sFLT measured in the emergency department are elevated in children with septic shock, and elevated sFLT but not VEGF is associated with worse clinical outcomes.

BACKGROUND: Although oral antibiotics are recommended for the management of most urinary tract infections (UTIs), the administration of parenteral antibiotics before emergency department (ED) discharge is common. We investigated the relationship between the administration of a single dose of parenteral antibiotics before ED discharge and revisits requiring admission among children with UTIs. METHODS: A retrospective analysis of administrative data from 36 pediatric hospitals was performed. Patients aged 29 days to 2 years who were evaluated in the ED with a UTI between 2010 and 2016 were studied. Primary outcome was adjusted 3-day ED revisit rates resulting in admission. All revisits, regardless of disposition, served as a secondary outcome. Average treatment effects were estimated by using inverse probability weighted regression, with adjustment for demographic factors, diagnostic testing, ED medications, and hospital-level factors. RESULTS: We studied 29 919 children with a median age of 8.6 (interquartile range: 5.1–13.8) months. Of those studied, 36% of the children received parenteral antibiotics before discharge. Patients who received parenteral antibiotics had similar adjusted rates of revisits leading to admission as those who did not receive parenteral antibiotics (1.3% vs 1.0%, respectively; risk difference: 0.3% [95% confidence interval: −0.01% to 0.6%]), although overall revisit rates were higher among patients who received parenteral antibiotics (4.8% vs 3.3%; risk difference 1.5% [95% confidence interval: 0.9% to 2.1%]). CONCLUSIONS: Among discharged patients, a parenteral dose of antibiotics did not reduce revisits leading to admission, supporting the goal of discharging patients with oral antibiotics alone for most children with UTIs.

BACKGROUND AND OBJECTIVES: The ability of the chest radiograph (CXR) to exclude the diagnosis of pneumonia in children is unclear. We sought to determine the negative predictive value of CXR in children with suspected pneumonia. METHODS: Children 3 months to 18 years of age undergoing CXRs for suspected pneumonia in a tertiary-care pediatric emergency department (ED) were prospectively enrolled. Children currently receiving antibiotics and those with underlying chronic medical conditions were excluded. The primary outcome was defined as a physician-ascribed diagnosis of pneumonia independent of radiographic findings. CXR results were classified as positive, equivocal, or negative according to radiologist interpretation. Children with negative CXRs and without a clinical diagnosis of pneumonia were managed for 2 weeks after the ED visit. Children subsequently diagnosed with pneumonia during the follow-up period were considered to have had false-negative CXRs at the ED visit. RESULTS: There were 683 children enrolled during the 2-year study period, with a median age of 3.1 years (interquartile range 1.4–5.9 years). There were 457 children (72.8%) with negative CXRs; 44 of these children (8.9%) were clinically diagnosed with pneumonia, and 42 (9.3%) were given antibiotics for other bacterial syndromes. Of the 411 children with negative CXRs who were managed without antibiotics, 5 were subsequently diagnosed with pneumonia within 2 weeks (negative predictive value of CXR 98.8%; 95% confidence interval 97.0%–99.6%). CONCLUSIONS: A negative CXR excludes pneumonia in the majority of children. Children with negative CXRs and low clinical suspicion for pneumonia can be safely observed without antibiotic therapy.

BACKGROUND: Patients with septic hip arthritis require surgical drainage, but they can be difficult to distinguish from patients with Lyme arthritis. The ability of synovial fluid white blood cell (WBC) counts to help discriminate between septic and Lyme arthritis of the hip has not been investigated. METHODS: We assembled a retrospective cohort of patients ≤21 years of age with hip monoarticular arthritis and a synovial fluid culture obtained who presented to 1 of 3 emergency departments located in Lyme disease endemic areas. Septic arthritis was defined as a positive synovial fluid culture result or synovial fluid pleocytosis (WBC count ≥50 000 cells per µL) with a positive blood culture result. Lyme arthritis was defined as positive 2-tiered Lyme disease serology results and negative synovial fluid bacterial culture results. All other patients were classified as having other arthritis. We compared median synovial fluid WBC counts by arthritis type. RESULTS: Of the 238 eligible patients, 26 (11%) had septic arthritis, 32 (13%) had Lyme arthritis, and 180 (76%) had other arthritis. Patients with septic arthritis had a higher median synovial fluid WBC count (126 130 cells per µL; interquartile range 83 303–209 332 cells per µL) than patients with Lyme arthritis (53 955 cells per µL; interquartile range 33 789–73 375 cells per µL). Eighteen patients (56%) with Lyme arthritis had synovial fluid WBC counts ≥50 000 cells per µL. Of the 94 patients who underwent surgical drainage, 13 were later diagnosed with Lyme arthritis. CONCLUSIONS: In Lyme disease endemic areas, synovial fluid WBC counts cannot always help differentiate septic from Lyme arthritis. Rapid Lyme diagnostics could help avoid unnecessary operative procedures in patients with Lyme arthritis.

OBJECTIVES: We sought to develop and validate a clinical calculator that can be used to quantify risk for appendicitis on a continuous scale for patients with acute abdominal pain. METHODS: The pediatric appendicitis risk calculator (pARC) was developed and validated through secondary analyses of 3 distinct cohorts. The derivation sample included visits to 9 pediatric emergency departments between March 2009 and April 2010. The validation sample included visits to a single pediatric emergency department from 2003 to 2004 and 2013 to 2015. Variables evaluated were as follows: age, sex, temperature, nausea and/or vomiting, pain duration, pain location, pain with walking, pain migration, guarding, white blood cell count, and absolute neutrophil count. We used stepwise regression to develop and select the best model. Test performance of the pARC was compared with the Pediatric Appendicitis Score (PAS). RESULTS: The derivation sample included 2423 children, 40% of whom had appendicitis. The validation sample included 1426 children, 35% of whom had appendicitis. The final pARC model included the following variables: sex, age, duration of pain, guarding, pain migration, maximal tenderness in the right-lower quadrant, and absolute neutrophil count. In the validation sample, the pARC exhibited near perfect calibration and a high degree of discrimination (area under the curve: 0.85; 95% confidence interval: 0.83 to 0.87) and outperformed the PAS (area under the curve: 0.77; 95% confidence interval: 0.75 to 0.80). By using the pARC, almost half of patients in the validation cohort could be accurately classified as at 8. CONCLUSIONS: In our validation cohort of patients with acute abdominal pain, the pARC accurately quantified risk for appendicitis.

BACKGROUND: Emergency department (ED) revisits are used as a measure of care quality. Many EDs measure only revisits to the same facility, underestimating true rates. We sought to determine the frequency, location, and predictors of ED revisits to the same or a different ED. METHODS: We studied ED discharges for children RESULTS: Revisits across 261 EDs occurred after 5.9% of 4.3 million discharges. A per-ED median 21.9% of revisits were DHRs (interquartile range 14.2%–34.6%). Measuring only same-hospital revisits underestimated total revisits by 17.4%. The proportions of revisits that were DHRs by increasing volume quartile were 28.1%, 25.5%, 22.6%, and 14.5%. The adjusted risk of DHR was lower for increasing quartiles of pediatric volume (adjusted odds ratio for highest versus lowest quartile 0.27; 95% confidence interval, 0.19–0.36). CONCLUSIONS: Measuring ED revisits only at the index ED significantly underestimates total revisits. Lower pediatric volume is associated with higher DHRs as a proportion of revisits. When using revisits as a measure of emergency care quality, effort should be made to assess revisits to different EDs.

Isolated amnesia is an uncommon presenting complaint in the pediatric age group. We report the case of an 18-year-old woman who presented with the acute onset of memory difficulty and an otherwise normal neurologic examination. Brain magnetic resonance imaging demonstrated inflammation in the bilateral temporal lobes. Serum and cerebrospinal fluid testing ultimately revealed a diagnosis of autoimmune encephalitis. Although rare, the acute onset of isolated amnesia deserves a prompt, comprehensive evaluation.

Objective The objective of this study was to determine the incidence and recent trends in serious pediatric emergency conditions. Methods We conducted a cross-sectional study of the Nationwide Emergency Department Sample from 2008 through 2014, and included patients with age below 18 years with a serious condition, defined as each diagnosis group in the diagnosis grouping system with a severity classification system score of 5. We calculated national incidences for each serious condition using annualized weighted condition counts divided by annual United States census child population counts. We determined the highest-incidence serious conditions over the study period and calculated percentage changes between 2008 and 2014 for each serious condition using a Poisson model. Results The 2008 incidence of serious conditions across the national child population was 1721 visits per million person-years (95% confidence interval, 1485-1957). This incidence increased to 2020 visits per million person-years (95% confidence interval, 1661-2379) in 2014. The most common serious conditions were serious respiratory diseases, septicemia, and serious neurologic diseases. Anaphylaxis was the condition with the largest change, increasing by 147%, from 101 to 249 visits per million person-years. Conclusions The most common serious condition in children presenting to United States emergency departments is serious respiratory disease. Anaphylaxis is the fastest increasing serious condition. Additional research attention to these diagnoses is warranted.

Oral antibiotics effectively treat most pediatric urinary tract infections (UTIs); however, children with UTIs are frequently admitted. We examined variation and trends in admission for children with UTIs plus investigated the relationship between admission and emergency department (ED) revisits for those initially managed on an outpatient basis. We hypothesized that hospitals would have similar 3-day revisit rates regardless of the admission rate at the index visit.This was a retrospective analysis of 36 hospitals in the Pediatric Health Information System. ED visits for children aged2 years presenting with UTI between 2010 and 2016 were studied. Main outcomes were age-stratified and included admission and 3-day ED revisit rates. Regression analyses were used to test hospital-level associations between outcomes and linear temporal trends.A total of 41,792 visits were studied. The overall admission rate was 27%. The admission rate was 89% for children aged2 months and 15% for those aged 2 to 24 months. Interhospital admission rates varied from 6% to 64%. Admission and revisit rates were inversely related (mean change, -0.07; 95% confidence interval [CI], -0.13 to -0.02 per 1% increase in admission rate); however, lower admission rates were not associated with increased revisits leading to admission (mean change, -0.02; 95% CI, -0.07 to 0.03). Over the study period, admission rates were stable (test for linear trend: adjusted odds ratio [aOR], 0.99; 95% CI, 0.95-1.02); however, among infants aged2 months, admissions decreased (aOR, 0.92; 95% CI, 0.88-0.97).A substantial variation in admission rates exists for children with UTI. Although hospitals with lower admission rates had higher revisit rates, those hospitals did not have an increase in revisits with subsequent admission, supporting the goal of outpatient management.

Objective To determine the predictive value of ultrasonography (US) for appendicitis in children when combined with clinical assessment based on the Pediatric Appendicitis Score (PAS). Study design Observational study of children aged 3-18 years who had an US examination for possible appendicitis. A PAS was calculated on the basis of historical elements, examination, and laboratory studies and was used to classify patients into 3 risk groups (low, medium, high). The predictive value of the PAS for appendicitis was calculated and stratified by the result of the US (positive, negative, or equivocal). Results A total of 728 children with a median age 11.7 (IQR 7.8-14.9) years were studied; 29% had appendicitis. The negative predictive value of US decreased with increasing PAS-based risk assignment: low risk 1.00 (95% CI, 0.97-1.00), medium risk 0.94 (0.91-0.97), and high risk 0.81 (0.73-0.89). With increasing PAS, the positive predictive value increased: low risk 0.73 (0.47-0.99), medium risk 0.90 (0.82-0.98), and high risk 0.97 (0.95-1.0). Among children with equivocal ultrasound results, the proportion with appendicitis ranged from 0.09 (0.0-0.19) for low-risk patients to 0.47 (0.33-0.61) among for high-risk patients. Conclusion Ultrasound findings in children with possible appendicitis should be integrated with clinical assessment, such as a clinical score, to determine next steps in management. Rates of false-negative US increase with increasing PAS, and false-positive US results occur more often with lower PAS. When discordance exists between US results and the clinical assessment, serial examinations or further imaging are warranted.

BACKGROUND AND OBJECTIVES: Migraine headache is a common pediatric complaint among emergency department (ED) patients. There are limited trials on abortive therapies in the ED. The objective of this study was to apply a comparative effectiveness approach to investigate acute medication regimens for the prevention of ED revisits. METHODS: Retrospective study using administrative data (Pediatric Health Information System) from 35 pediatric EDs (2009–2012). Children aged 7 to 18 years with a principal diagnosis of migraine headache were studied. The primary outcome was a revisit to the ED within 3 days for discharged patients. The primary analysis compared the treatment regimens and individual medications on the risk for revisit. RESULTS: The study identified 32 124 children with migraine; 27 317 (85%) were discharged, and 5.5% had a return ED visit within 3 days. At the index visit, the most common medications included nonopioid analgesics (66%), dopamine antagonists (50%), diphenhydramine (33%), and ondansetron (21%). Triptans and opiate medications were administered infrequently (3% each). Children receiving metoclopramide had a 31% increased odds for an ED revisit within 3 days compared with prochlorperazine. Diphenhydramine with dopamine antagonists was associated with 27% increased odds of an ED revisit compared with dopamine antagonists alone. Children receiving ondansetron had similar revisit rates to those receiving dopamine antagonists. CONCLUSIONS: The majority of children with migraines are successfully discharged from the ED and only 1 in 18 required a revisit within 3 days. Prochlorperazine appears to be superior to metoclopramide in preventing a revisit, and diphenhydramine use is associated with increased rates of return.

Objectives Screening for urinary tract infection (UTI) includes urinary nitrite testing by dipstick urinalysis. Gram-negative enteric organisms produce urinary nitrite and represent the most common uropathogens. Enterococcus, a less common uropathogen, does not produce nitrite and has a unique antibiotic resistance pattern. Whether to adjust empiric antibiotics in the absence of urinary nitrite has not been established. Our primary objective was to determine prevalence of enterococcal UTI among young children with a nitrite negative urinalysis. Methods A retrospective study of children aged less than 2 years evaluated in the emergency department for possible UTI and had a paired urinalysis and urine culture was performed. Urinary tract infection was defined by catheterized culture yielding greater than or equal to 50,000 colony-forming units per milliliter of a single uropathogen. Prevalence of uropathogens among nitrite negative samples was studied. Results A total of 7599 children were studied. Median (interquartile range) age was 5.6 (2.3-11.2) months, and 57% were female. Prevalence of UTI was 8.1%. Enterococcus was the uropathogen in 2.1% of UTIs, and all cases had negative dipstick nitrite. Among nitrite negative UTIs, 95.6% of uropathogens were gram-negative and only 3.2% (confidence interval, 1.8%-5.3%) were enterococcus. None of the 200 UTIs with positive nitrite yielded enterococcus (upper confidence interval, 1.4%). Among children with positive leukocyte esterase and negative nitrite, only 0.7% of cases had enterococcal UTI. Conclusions Only 3% of nitrite negative UTIs were caused by enterococcus. Given the low prevalence of enterococcal UTI, the absence of dipstick nitrite should not affect routine empiric antibiotic choice for presumptive UTI in young children.

BACKGROUND AND OBJECTIVES: Pediatric out-of-hospital cardiac arrest (OHCA) has a low rate of survival to hospital discharge. Understanding whether pediatric emergency departments (EDs) have higher survival than general EDs may help identify ways to improve care for all patients with OHCA. We sought to determine if OHCA survival differs between pediatric and general EDs. METHODS: We used the 2009–2014 Nationwide Emergency Department Sample to study children under 18 with cardiac arrest. We compared pediatric EDs (those with >75% pediatric visits) to general EDs on the outcome of survival to hospital discharge or transfer. We determined unadjusted and adjusted survival, accounting for age, region, and injury severity. Analyses were stratified by nontraumatic versus traumatic cause. RESULTS: The incidences of nontraumatic and traumatic OHCA were 7.91 (95% confidence interval [CI]: 7.52–8.30) and 2.67 (95% CI: 2.49–2.85) per 100 000 person years. In nontraumatic OHCA, unadjusted survival was higher in pediatric EDs than general EDs (33.8% vs 18.9%, P < .001). The adjusted odds ratio of survival in pediatric versus general EDs was 2.2 (95% CI: 1.7–2.8). Children with traumatic OHCA had similar survival in pediatric and general EDs (31.7% vs 26.1%, P = .14; adjusted odds ratio = 1.3 [95% CI: 0.8–2.1]). CONCLUSIONS: In a nationally representative sample, survival from nontraumatic OHCA was higher in pediatric EDs than general EDs. Survival did not differ in traumatic OHCA. Identifying the features of pediatric ED OHCA care leading to higher survival could be translated into improved survival for children nationally.

BACKGROUND AND OBJECTIVES: Nonoperative management (NOM) of uncomplicated pediatric appendicitis has promise but remains poorly studied. NOM may lead to an increase in resource utilization. Our objective was to investigate the trends in NOM for uncomplicated appendicitis and study the relevant clinical outcomes including subsequent appendectomy, complications, and resource utilization. METHODS: Retrospective analysis of administrative data from 45 US pediatric hospitals. Patients RESULTS: 99 001 children with appendicitis were identified, with a median age of 10.9 years. Sixty-six percent were diagnosed with nonperforated appendicitis, of which 4190 (6%) were managed nonoperatively. An increasing number of nonoperative cases were observed over 6 years (absolute difference, +20.4%). During the 12-month follow-up period, NOM patients were more likely to have the following: advanced imaging (+8.9% [95% confidence interval (CI) 7.6% to 10.3%]), ED visits (+11.2% [95% CI 9.3% to 13.2%]), and hospitalizations (+43.7% [95% CI 41.7% to 45.8%]). Among patients managed nonoperatively, 46% had a subsequent appendectomy. CONCLUSIONS: A significant increase in NOM of nonperforated appendicitis was observed over 6 years. Patients with NOM had more subsequent ED visits and hospitalizations compared with those managed operatively at the index visit. A substantial proportion of patients initially managed nonoperatively eventually had an appendectomy.

Objectives The aims of this study were to (1) assess the reasons for pediatric interfacility transfers as identified by transferring providers and review the emergency medical care delivered at the receiving facilities and (2) investigate the emergency department (ED) care among the subpopulation of patients discharged from the receiving facility. Methods We performed a multicenter, cross-sectional survey of ED medical providers transferring patients younger than 18 years to 1 of 4 US tertiary care pediatric hospitals with a subsequent medical record review at the receiving facility. Referring providers completed surveys detailing reasons for transfer. Results Eight hundred thirty-nine surveys were completed by 641 providers for 25 months. The median patient age was 5.7 years. Sixty-two percent of the patients required admission. The most common reasons for transfer as cited by referring providers were subspecialist consultation (62%) and admission to a pediatric inpatient (17%) or intensive care (6%) unit. For discharged patients, plain radiography (26%) and ultrasonography (12%) were the most common radiologic studies. Procedural sedation (16%) was the most common ED procedure for discharged patients, and 55% had a subspecialist consult at the receiving facility. Ten percent of interfacility transfers did not require subspecialty consult, ED procedure, radiologic study, or admission. Conclusions Approximately 4 of 10 interfacility transfers are discharged by the receiving facility, suggesting an opportunity to provide more comprehensive care at referring facilities. On the basis of the care provided at the receiving facility, potential interventions might include increased subspecialty access and developing both ultrasound and sedation capabilities.

Children with recurrent urinary tract infections (rUTI) often show no identifiable cause of their infections. Neutrophil gelatinase-associated lipocalin (NGAL) is known to be upregulated within the uroepithelium and kidney of patients with UTI and exhibits a localized bacteriostatic effect through iron chelation. We hypothesize that some patients with rUTI without an identifiable cause of their recurrent infections have locally deficient NGAL production. We therefore explored whether a lack of NGAL production may be a factor in the pathogenesis of rUTI.Patients seen in the urology clinic for rUTI who were21 years of age were enrolled. Patients were excluded if they had UTI at the time of enrollment, evidence of renal disease, decreased renal function, known anatomic abnormality of the genitourinary tract, or other reasons that predispose to UTI, such as neurogenic bladder, the need for intermittent catheterization, or unrepaired posterior urethral valves. Control patients were healthy children enrolled from the emergency department with no history of UTI or renal dysfunction, normal urinalysis at the time of enrollment, and presenting no diagnosis associated with increased NGAL levels, such as acute kidney injury or infection. NGAL was measured by immunoblot.Fifteen cases and controls were enrolled. Median urinary NGAL levels were significantly decreased in rUTI patients compared with controls [15 (14-29) ng/ml vs 30 (27-61) ng/ml; p = 0.002)] Although comparatively diminished, measurable NGAL levels were present in all patients with rUTI.Urinary NGAL is significantly decreased in patients with compared with patients without rUTI. These data suggest that some patients with rUTI may be predisposed to UTI because of a relative local deficiency in urinary NGAL production.

BACKGROUND: Provision of high-quality care to acutely ill and injured children is a challenge to US hospitals because many have low pediatric volume. Delineating national trends in definitive pediatric acute care would inform improvements in care. METHODS: We analyzed emergency department (ED) visits by children between 2008 and 2016 in the Nationwide Emergency Department Sample, a weighted sample of 20% of EDs nationally. For each hospital annually, we determined the Hospital Capability Index (HCI) to determine the frequency of definitive acute care, defined as hospitalization instead of ED transfer. Hospitals were classified annually according to 2008 HCI quartiles to understand shifts in pediatric capability. RESULTS: The national median HCI was 0.06 (interquartile range: 0.01–0.17) in 2008 and 0.02 (interquartile range: 0.00–0.09) in 2016 (P CONCLUSIONS: Across the United States from 2008 to 2016, hospital provision of definitive acute pediatric care decreased, and ED visits to the hospitals least likely to provide definitive care increased. Systems improvements are needed to support hospital-based acute care of children.

To investigate the risk of critical illness by age group among young children without a chronic condition presenting to the emergency department (ED) with suspected influenza.Retrospective study of patients aged2 years presenting to the ED with suspected influenza (defined by diagnostic codes for influenza or influenza-like illness) from 2009 to 2017 in 49 hospitals in the Pediatric Health Information System. Patients with chronic conditions were excluded. The main clinical outcomes were intensive care unit (ICU) admission, ventilatory support, vasopressor administration, and mortality, which were compared independently by age group (3 months, 3 to6 months, 6 to12 months, and 12 to24 months). To compare outcomes by age, we estimated the prevalence of each outcome by age group after fitting logistic regression models to control for demographic differences between groups.A total of 55 986 children were studied. Overall admission and ICU admission rates were 20% and 2%, respectively. After adjustment for demographic variables, infants aged3 months had higher rates of ICU admission (2.7%; 95% CI, 2.0%-3.3%; P .001 compared with other age groups) and ventilatory support (2.5%; 95% CI, 1.9%-3.2%; P .001 compared with other age groups); however, there were no differences in vasopressor administration. The overall case fatality rate was low (0.007%) and thus could not be compared across age groups.Infants aged3 months with suspected influenza are at greatest risk for critical illness. Although critical illness is uncommon, these findings should be incorporated into acute management decisions, including the need for specified outpatient follow-up or hospitalization, and public health efforts should focus on prevention and disease-modifying interventions in this high-risk population.

To improve the prediction of pediatric pneumonia by developing a series of models based on clinically distinct subgroups. We hypothesized that these subgroup models would provide superior estimates of pneumonia risk compared with a single pediatric model.We conducted a secondary analysis of a prospective cohort being evaluated for radiographic pneumonia in an urban pediatric emergency department (ED). Using multivariate modeling, we created 4 models across subgroups stratified by age and presence of wheezing to predict the risk of pneumonia.A total of 2351 patients were included in the study. In this series, the prevalence of pneumonia was 8.5%, and 21.6% were hospitalized. The highest prevalence of pneumonia was in children aged2 years without wheezing (13.3%). Children aged2 years with wheezing had the lowest prevalence of pneumonia (4.0%). The most accurate model was for children aged2 years with wheezing (area under the curve [AUC], 0.80), and the poorest performing model was for those aged2 years without wheezing (AUC, 0.64). The AUC of a combination of the 4 subgroup models was 0.76 (95% CI, 0.72-0.80). The precision of the models' estimates (expected vs observed) was ± 3.7%.Using 4 complementary prediction models for pediatric pneumonia, an accurate risk of pneumonia can be calculated. These models can provide the basis for clinical decision making support to guide the use of chest radiographs and promote antibiotic stewardship.

OBJECTIVE Providing meaningful evaluation to trainees rotating through the pediatric emergency medicine is important yet challenging. Information systems can be used to autopopulate an electronic case log, which can be leveraged to assist in the evaluation process. The objective of this study was to determine if a novel educational initiative using an automated case log improved faculty evaluation of trainees. METHODS This retrospective study examined faculty completion rate, as well as the content of medical student evaluations over a 3-academic-year study period. Three phases of evaluation were utilized: written, electronic, and electronic enhanced with individualized case reports created with the automated case log. The primary outcome was faculty response rate. Secondary outcomes included word count and the number of themes identified following qualitative analysis of narrative responses. Logistic regression was performed. RESULTS Forty-one faculty members completed evaluations of 43 students. The rates of completion for the written, electronic, and automated case log phases were 18%, 16%, and 62%, respectively. Faculty in the automated case log phase were significantly more likely to complete evaluations compared with those in the written evaluation phase (odds ratio, 7.6; 95% confidence interval, 4.5-13.0). The median word counts across the 3 phases were 19, 36, and 43, respectively. The median numbers of themes identified during the 3 phases were 3, 4, and 5, respectively. The differences in the word count and median number of themes between the written and automated case log phases were significantly different (P < 0.001). CONCLUSIONS The process of trainee evaluation can be improved by utilizing an automated case log to provide faculty members with individualized reports of shared patient encounters.
