Objectives Differences in emergency care for children exist between general and pediatric emergency departments (EDs). Some pediatric quality measures are available but are not routinely employed nationwide. We sought to create a short list of applied measures that would provide a starting point for EDs to measure pediatric emergency care quality and to compare care between general and pediatric EDs for these measures. Methods Previously reported lists comprising 465 pediatric emergency care quality measures were reconciled. Preset criteria were used to create a diverse list of quality measures measurable using a national database. We used the National Hospital Ambulatory Medical Care Survey from 2010 to 2015 to measure performance. Measures were excluded for total observation counts under a prespecified power threshold, being unmeasurable in the data set, or for missing clear definitions. Using survey-weighted statistics, we reported summary performance (mean, proportion, or count) with 95% confidence intervals for each analyzed quality measure and compared general and pediatric ED performance. Results Among 465 quality measures, 28 (6%) were included in the analysis, including seven condition-specific measures and 21 general measures. We analyzed a sample of 36,430 visits corresponding to 179.0 million survey-weighted ED visits, of which 150.8 million (84.3%) were in general EDs. Performance was better in pediatric EDs for three of seven condition-specific measures, including antibiotics for viral infections (-6.2%), chest X-rays for asthma (-18.7%), and topical anesthesia for wound closures (+25.7%). Performance was similar for four of seven condition-specific measures: computed tomography for head trauma, steroids for asthma, steroids for croup, and oral rehydration for dehydration. Compared with pediatric EDs, general EDs discharged and transferred higher proportions of children, had shorter lengths of stay, and sent patients home with fewer prescriptions. General EDs obtained fewer pain scores for injured children. Pediatric EDs had a lower proportion of pediatric visits in which patients left against medical advice. General and pediatric EDs had similar rates of mortality, left without being seen, incomplete vital signs, labs in nonacute patients, and similar numbers of medications given per patient. Conclusions Using a national sample of ED visits, we demonstrated the feasibility of using nationally representative data to assess quality measures for children cared for in the ED. Differences between pediatric and general ED care identify targets for quality improvement.

OBJECTIVE The use of computed tomography (CT) and ultrasound (US) in patients with acute abdominal pain has substantial variation across pediatric emergency departments (EDs). This study compares the cost of diagnosing and treating suspected appendicitis across a multicenter network of children's hospitals. METHODS This study is a secondary analysis using deidentified data of a prospective, observational study of patients with suspected appendicitis at nine pediatric EDs. The study included patients 3 to 18 years old who presented to the ED with acute abdominal pain of

OBJECTIVE White blood cell (WBC) count and absolute neutrophil count (ANC) are a standard part of the evaluation of suspected appendicitis. Specific threshold values are utilized in clinical pathways, but the discriminatory value of WBC count and ANC may vary by age. The objective of this study was to investigate whether the diagnostic value of WBC count and ANC varies across age groups and whether diagnostic thresholds should be age-adjusted. METHODS This is a multicenter prospective observational study of patients aged 3-18 years who were evaluated for appendicitis. Receiver operator characteristic curves were developed to assess overall discriminative power of WBC count and ANC across three age groups

Objectives The objective was to determine the frequency of postreduction, hospital-level interventions among children with successful reduction of ileocolic intussusception and identify factors that predict the need for such interventions. Methods This was a retrospective cross-sectional study of children who underwent successful enema reduction for ileocolic intussusception at a single emergency department. Hospital-level interventions were included if they occurred within 24 hours of reduction and were further classified as either major (recurrence or possible perforation) or minor (imaging for suspected recurrence or administration of parenteral narcotics or antiemetics). Binary logistic regression was used to identify predictors for hospital-level interventions. Results A total of 464 children underwent enema reduction. The median age was 1.7 years (interquartile range [IQR] = 0.8 to 2.5 years), and 66% were male. A total of 435 (94%) were hospitalized with a median hospital stay of 25 hours (IQR = 19 to 34 hours). Nineteen percent (95% confidence interval [CI] = 15% to 22%) needed postreduction interventions, including 6% (95% CI = 4% to 9%) who required major interventions. The median time to any hospital intervention was 9.9 hours (IQR = 6.3 to 16.4 hours). We identified two independent predictors for hospital-level interventions: duration of symptoms > 24 hours (adjusted odds ratio [OR] = 2.1, 95% CI = 1.3 to 3.4) and location of the intussusception tip at (or proximal to) the hepatic flexure (adjusted OR = 1.9, 95% CI = 1.1 to 3.3); the latter factor was also a predictor of a major intervention. None of the children (95% CI = 0 to 1.0%) had an acute decompensation after an initially successful enema reduction. Conclusions Clinical decompensation is rare and recurrence is relatively low after an uncomplicated reduction of ileocolic intussusception. However, one in five children required hospital-level interventions after reduction. Children with the intussusception tip at (or proximal to) the hepatic flexure, and those with symptoms for longer than 24 hours, are more likely to require subsequent interventions. Although outpatient management appears safe after a period of observation, caregivers should be counseled about the risk of ongoing symptoms and recurrence.

Emergency department (ED) crowding may affect disposition decision-making. The objective was to measure the effect of ED crowding on probability of admission and return visit to the ED after discharge.The authors studied a historical cohort at a large pediatric ED over 40 months. Each patient was assigned a score on arrival based on the ED occupancy rate (the ratio of patients to beds). Patients were divided into quintiles by occupancy rate. The proportion admitted for each quintile was compared to the least crowded quintile adjusting for acuity, hospital occupancy, and time of arrival. The same analysis was performed for return visits to the ED within 48 hours. The analyses were repeated for the subsets of patients with asthma and with gastroenteritis and/or dehydration.From the 40 months of historical data, 198,778 visits were analyzed. The adjusted odds ratio (aOR) for admission among the whole cohort was 0.85 (95% confidence interval [CI]=0.81 to 0.89) comparing the highest to the lowest crowding quintiles (occupancy rate1.17 and0.54, respectively). For asthma patients, aOR=0.93 (95% CI=0.72 to 1.20), and for gastroenteritis patients, aOR=0.87 (95% CI=0.65 to 1.17). The aOR of return visits comparing the highest to the lowest crowding quintiles for all patients was aOR=0.87 (95% CI=0.79 to 0.97), for asthma patients was aOR=1.52 (95% CI=0.95 to 2.46), and for gastroenteritis patients was aOR=0.83 (95% CI=0.54 to 1.28).Increasing ED crowding is associated with a lower likelihood of hospital admission and lower frequency of return visits within 48 hours.

Objectives: To compare the interexaminer reliability and ability to predict appendicitis between pediatric emergency physicians (EPs) and senior surgical residents. Methods: The authors conducted a prospective cohort study of children aged 3 to 18 years of age with signs and symptoms suspicious for appendicitis. Patients were initially examined by a pediatric EP attending and then by a consulting senior surgical resident. Physicians reported the presence or absence of specific historical and physical exam findings and predicted the likelihood the patient had appendicitis. Interexaminer reliability of historical and physical exam findings was compared (kappa statistic). Distributions and median probabilities of appendicitis were calculated for pediatric EP and surgeon predictions. Results: The authors evaluated 350 patients with acute abdominal pain. Historical questions revealed slight to very good agreement (kappa statistic range 0.33–0.82) between physician types, whereas physical examination findings exhibited poor to fair agreement (range 0.14–0.48). Physicians predicted similar median probabilities of appendicitis for patients who were ultimately diagnosed with appendicitis (75% vs. 70%; p = 0.73) and patients without appendicitis (25% vs. 30%; p = 0.59). For a subset of patients given a ‡ 90% predicted probability of appendicitis, pediatric EPs and senior surgical residents had similar accuracy (80% vs. 79%; p = 0.92). Similarly, among patients with £ 10% predicted probability, pediatric EPs were correct in 95% and senior surgical residents correct in 94% of patients (p = 0.63). Conclusions: Pediatric EPs and senior surgical residents elicit historical findings from patients with suspected appendicitis with a greater degree of similarity than physical examination findings, which exhibit a wide degree of variability. Pediatric EPs and senior surgical residents do not differ in their ability to clinically predict appendicitis. These findings may be helpful in developing institutional management protocols.

Background: Rapid intravenous (IV) rehydration in the emergency department (ED) is required for certain children with acute gastroenteritis (AGE). Objectives: To determine whether the amount of IV dextrose administered is related to a return visit with admission (RVA) in children with AGE and dehydration, and to determine which clinical, laboratory, and treatment parameters are associated with an RVA. Methods: The investigators performed a case control study of children aged 6 months to 6 years who presented to an urban ED with AGE and dehydration and who received IV rehydration before discharge from the ED. Dehydration was defined a priori on the basis of parameters used in prior studies. Cases were defined as those patients who had an RVA within 72 hours of an original visit for ongoing symptoms. Controls were defined as those patients who met inclusion criteria who did not have an RVA. The authors studied whether the amount of IV dextrose administered at the initial visit was related to an RVA as well as which other clinical and treatment parameters were associated with an RVA. Results: A total of 56 cases and 112 controls were studied. Patients who had an RVA received significantly less IV dextrose (mean: 399 mg/kg vs. 747 mg/kg, p < 0.001) than those who did not have an RVA. Patients who received no IV dextrose had 3.9 times greater odds of having a return visit with admission than those who received some dextrose. Controlling for fluid volume, the amount of dextrose administered remained statistically significant by logistic regression; for every 500 mg/kg of IV dextrose administered, the patient was 1.9 times less likely to have an RVA. Patients with length of symptoms less than or equal to one day were more likely to have an RVA than were those with symptom length of two or more days. No other historical or physical exam findings or laboratory parameters (including mean serum bicarbonate) were associated with a return visit requiring admission. Conclusions: Administration of larger amounts of IV dextrose is associated with reduced return visits requiring admission in children with gastroenteritis and dehydration.

Background: The utility of chest radiographs (CXRs) for detecting occult pneumonia (OP) among pediatric patients without lower respiratory tract signs has been previously studied, but no predictors other than white blood cell count (WBC) and height of fever have been investigated. Objectives: To identify predictors of OP in pediatric patients in the postconjugate pneumococcal vaccination era. Methods: This was a retrospective cross sectional study that was conducted in a large urban pediatric hospital. Physician records of emergency department (ED) patients of age 10 years or less who presented with fever (≥38°C) and had a CXR obtained for suspected pneumonia were reviewed. Patients were classified into two groups: “signs of pneumonia” and “no signs of pneumonia” on the basis of the presence or absence of respiratory distress, tachypnea, or lower respiratory tract findings. Occult pneumonia was defined as radiographic pneumonia in a patient without signs of pneumonia. Results: Two thousand one hundred twenty-eight patients were studied. Among patients categorized as having no signs of pneumonia (n = 1,084), 5.3% (95% CI = 4.0% to 6.8%) had OP. Presence of cough and longer duration of cough (greater than 10 days) had positive likelihood ratios (LR+) of 1.24 (95% CI = 1.15 to 1.33) and 2.25 (95% CI = 1.21 to 4.20), respectively. Absence of cough had a negative likelihood ratio (LR−) of 0.19 (95% CI = 0.05 to 0.75). The likelihood of OP increased with increasing duration of fever (LR+ for more than three days and more than five days of fever, respectively: 1.62; 95% CI = 1.13 to 2.31 and 2.24; 95% CI = 1.35 to 3.71). When obtained (56% of patients), WBC was a predictor of OP, with a LR+ of 1.76 (95% CI = 1.40 to 2.22) and 2.17 (95% CI = 1.58 to 2.96) for WBC of >15,000/mm3 and >20,000/mm3, respectively. Conclusions: Occult pneumonia was found in 5.3% of patients with fever and no lower respiratory tract findings, tachypnea, or respiratory distress. There is limited utility in obtaining a CXR in febrile children without cough. The likelihood of pneumonia increased with longer duration of cough or fever or in the presence of leukocytosis.

Background The diagnosis of appendicitis remains challenging in children. Delays in diagnosis, or misdiagnosis, have important medical and legal implications. The typical, or classic, presentation of pediatric appendicitis has been modeled after adult disease; however, many children present atypically with subtle findings or unusual signs. Objectives To determine the frequency of atypical clinical features among pediatric patients with appendicitis and to investigate which atypical features are the strongest negative predictors for appendicitis among patients being evaluated for appendicitis. Methods Children and adolescents with suspected appendicitis were enrolled over 20 consecutive months. Pediatric emergency physicians completed standardized data collection forms on eligible patients. Final diagnosis was determined by pathology or follow-up telephone call. Typical and atypical findings were defined strictly a priori. Results Seven hundred fifty-five patients were enrolled. The median age was 11.9 years (interquartile range [IQR]: 8.5, 14.9 yr); 36% of patients were diagnosed with appendicitis. Among patients with appendicitis, the most common atypical features included absence of pyrexia (83%), absence of Rovsing's sign (68%), normal or increased bowel sounds (64%), absence of rebound pain (52%), lack of migration of pain (50%), lack of guarding (47%), abrupt onset of pain (45%), lack of anorexia (40%), absence of maximal pain in the right lower quadrant (32%), and absence of percussive tenderness (31%). Forty-four percent of patients with proven appendicitis had six or more atypical characteristics. The median number of atypical features for patients with proven appendicitis was five (IQR: 4.0, 7.0). The greatest negative predictors, on the basis of likelihood ratios, were as follows: white blood cell count (WBC) of

Objective: To determine whether parenteral antibiotics are superior to oral antibiotics in preventing serious bacterial infections in children with Streptococcus pneumoniae occult bacteremia. Methods: Using the MEDLINE database, the English language literature was searched for all publications concerning bacteremia, fever, or Streptococcus pneumoniae from 1966 to January 1, 1997. All nondupli-cative studies with a series of children with S. pneumoniae occult bacteremia having both orally treated and parenterally treated groups were reviewed. Children were excluded from individual studies if at the time of their initial evaluation they were immuno-compromised, had a serious bacterial infection, underwent a lumbar puncture, or did not receive antibiotics. Results: Only 4 studies met study criteria. From these studies, 511 total cases of S. pneumoniae occult bacteremia were identified. Ten of 290 (3.4%) in the oral group and 5 of 221 (2.3%) in the parenteral antibiotic group developed serious bacterial infections (pooled p-value = 0.467, pooled OR = 1.48; 95% CI, 0.5–4.3). Two patients in the oral group (0.7%) and 2 patients in the parenteral group (0.9%) developed meningitis (pooled p-value = 0.699, pooled OR = 0.67; 95% CI, 0.1–5.1). Conclusion: The rates of serious bacterial infections and meningitis did not differ between children who were treated with oral and parenteral antibiotics. The extremely low rate of complications observed in both groups suggests no clinically significant difference between therapies. A study with > 7,500 bacteremic children (or >300,000 febrile children) would be needed to have 80% power to prove parenteral antibiotics are superior to oral antibiotics in preventing serious bacterial infections.
