Abstract
A review of the evidence on epidemiology, risk factors, etiology and clinical-etiological profile of acute bronchiolitis is presented. The frequency estimates are very heterogeneous; in the population under two years the frequency of admission for bronchiolitis is between 1 and 3.5%, primary care consultations between 4 and 20% and emergency visits between 1 and 2%. The frequency of admissions for respiratory infection by respiratory syncytial virus in the risk population is: in premature infants < or =32 weeks of gestation between 4.4 and 18%, in patients with bronchopulmonary dysplasia between 7.3 and 42%, and in infants with congenital heart disease between 1.6 and 9.8%. The main risk factors are: prematurity, chronic lung disease or bronchopulmonary dysplasia, congenital heart disease and age less than 3-6 months at onset of the epidemic. Other factors are: older siblings or day care attendance, male gender, exposure to smoking, breastfeeding for less than 1-2 months and variables associated with lower socioeconomic status. Respiratory syncytial virus is the dominant etiological agent, constituting just over half the cases (median 56%; interval 27% to 73%). Other viruses implicated, in descending order of frequency, are rhinovirus, adenovirus, metapneumovirus, influenza viruses, parainfluenza, enterovirus and bocavirus. In studies with genomic detection techniques, between 20 and 25% of cases the virus involved is not identified and between 9% and 27% of cases have viral co-infection. Although respiratory syncytial virus bronchiolitis shows more wheezing and retractions, longer duration of respiratory symptoms and oxygen therapy and are associated with lower use of antibiotics. This pattern is associated with the younger age of the patients and does not help us to predict the etiology. In general, the etiological identification is not useful for the management of patients. However, in young infants (<3 months) with febrile bronchiolitis in the hospital environment, conservative management may help these patients and avoid diagnostic and therapeutic procedures.

Abstract
OBJECTIVES Emergency department (ED) length of stay (LOS) is a quality of care measure and, when prolonged, contributes to ED crowding. Bronchiolitis, a common seasonal illness of infants, provides an opportunity to examine factors affecting ED LOS. METHODS We analyzed data from a 30-center prospective cohort study of ED patients younger than 2 years with an attending physician diagnosis of bronchiolitis to determine what factors affect LOS. Researchers conducted a structured interview and chart review. RESULTS Among 1459 children enrolled, ED LOS was available for 1416 children (97%). The median ED LOS was 3.3 hours (interquartile range, 2.3-4.8 hours). Multivariate analysis demonstrated that factors significantly (P < 0.05) associated with ED LOS were larger annual ED visit volume (reference, lowest tertile [< 44,134 visits], 44,134-62,420 [β = 0.74], and ≥ 62,421 [β = 0.63]), Hispanic race/ethnicity (reference, white race, β = 1.43), lack of primary care provider (β = 1.28), duration of symptoms of 4 to 7 days (reference, < 1 day; β = 0.58), presentation of midnight to 7 AM (reference, 4:00-11:59 PM; β = 1.07), decreasing lowest oxygen saturation in ED (β = 0.07), fewer number of A-agonists during the first hour (β = 0.74), unknown oral intake (reference, adequate; β = 0.69), performance of chest x-ray (β = 0.62), and hospital admission (β = 1.11). CONCLUSIONS In this prospective multicenter study of children younger than 2 years with bronchiolitis, multiple factors were associated with longer ED LOS. These factors suggest the following steps to help shorten ED LOS: optimizing translation services, improving primary care provider rates, enhancing overnight patient flow, forgoing chest x-rays, and developing evidence-based admission criteria.

Abstract
OBJECTIVE We sought to identify predictors of the major medical intervention (MMI) in infants with bronchiolitis in the Emergency Department (ED) to recognize those in need of hospitalization versus the candidates for discharge. PATIENTS AND METHODS We conducted an analysis of data from a prospective cohort study of previously healthy infants 2-23 months presenting to our ED with first episode of wheeze and respiratory distress. Infants were divided into those with at least one MMI defined as oxygen administration for saturation of <90%, intravenous (IV) fluids of 20 ml/kg, apnea management, or critical care unit (CCU) admission (MMI group) versus those without (no-MMI group). The primary outcome was the association between the MMI versus no-MMI groups and potential risk factors for these outcomes. RESULTS Of 312 study infants, 52 experienced MMI--all received oxygen for saturation <90%, four also received IV fluids and none required apnea management or CCU care. The following four risk factors were associated with MMI: baseline accessory muscle score >or=6/9 [OR 2.44, 95% CI 1.29; 4.62], oxygen saturation <or=92% [OR 2.41, 95% CI 0.96; 6.14], respiratory rate >or=60 [OR 1.85, 95% CI 0.97; 3.54], and poor fluid intake [OR 2.65, 95% CI 1.12; 6.26]. Of the 148 infants without predictors 11 (7.4%) received MMI, 145 required either no MMI or oxygen for <or=6 hr and 130 (87.8%) stayed for <or=12 hr. CONCLUSIONS Infants with bronchiolitis with high-risk predictors should be hospitalized whereas those without can be considered for outpatient management due to low-risk of MMI.

Abstract
OBJECTIVE Infants with respiratory syncytial virus (RSV) infection are at risk for developing apnea. The authors compared patients with RSV infection who develop apnea with those who do not, to help ambulatory physicians risk stratify their patients with RSV infection. METHODS Entry criteria were age less than 1 year, RSV infection, and presentation to the authors' pediatric emergency departments. Random and weighted sampling techniques were used to identify the study group and provide the control sample. Charts were abstracted for 34 clinical variables. RESULTS The study group consisted of 42 patients with apnea, and the control group consisted of 198 patients without apnea. Logistic regression analysis identified 2 independent variables associated with apnea: young age and presentation with apnea. Most patients with apnea were less than 2 months of age and were ill for less than 5 days. CONCLUSIONS Age and duration of illness may help clinicians determine which previously healthy infants are at risk for apnea.

Abstract
OBJECTIVES The authors sought to identify predictors of intensive care unit (ICU) admission among children hospitalized with bronchiolitis for > or =24 hours. METHODS The authors conducted a prospective cohort study during two consecutive bronchiolitis seasons, 2004 through 2006, in 30 U.S. emergency departments (EDs). All included patients were aged <2 years and had a final diagnosis of bronchiolitis. Regular floor versus ICU admissions were compared. RESULTS Of 1,456 enrolled patients, 533 (37%) were admitted to the regular floor and 50 (3%) to the ICU. Comparing floor and ICU admissions, multivariate ED predictors of ICU admission were age <2 months (26% vs. 53%; odds ratio [OR] = 4.1; 95% confidence interval [CI] = 2.1 to 8.3), an ED visit the past week (25% vs. 40%; OR = 2.2; 95% CI = 1.1 to 4.4), moderate/severe retractions (31% vs. 48%; OR = 2.6; 95% CI = 1.3 to 5.2), and inadequate oral intake (31% vs. 53%; OR = 3.3; 95% CI = 1.6 to 7.1). Unlike previous studies, no association with male gender, socioeconomic factors, insurance status, breast-feeding, or parental asthma was found with ICU admission. CONCLUSIONS In this prospective multicenter ED-based study of children admitted for bronchiolitis, four independent predictors of ICU admission were identified. The authors did not confirm many putative risk factors, but cannot rule out modest associations.

Abstract
OBJECTIVES The purpose of our study was to explore the effect of the physician's training level on the emergency management of common illnesses in the pediatric emergency department (ED). Our hypothesis was that physicians in training used more resources than attending physicians did in caring for pediatric patients in the ED. METHODS We retrospectively reviewed all records of patients younger than 18 years who presented to the pediatric section in ED of Taipei Veterans General Hospital between January 1, 2004, and December 31, 2005. The cohort study was composed of patients treated by a pediatric attending physician (group 1) or treated by a resident (group 2). We collected their demographic data, diagnoses, admission and revisiting rates, direct costs (including radiographic, laboratory, and medication costs per visit), and utilization data. RESULTS Admission and 72-hour revisiting rates did not differ between groups. Lengths of ED stay and total, radiographic, and medication costs significantly increased with the residents (all P < 0.001). Residents ordered more radiographic (30.7% vs 23.8%, P < 0.001) and laboratory (37.2% vs 34.6%, P = 0.13) studies than attending physicians did, notably when patients had acute bronchitis and bronchiolitis or noninfectious gastroenteritis and colitis. Residents also ordered more laboratory studies in cases of pneumonia. CONCLUSIONS Residents treating pediatric patients in the ED spent more time and used more medical resources than attending physicians did. An important educational objective is to improve physicians' diagnostic skills to reduce resource utilization and to improve outcomes.

Abstract
OBJECTIVE Bronchiolitis is the leading cause of hospitalization for infants. Our objective was to identify factors associated with safe discharge to home from the emergency department. METHODS We conducted a prospective cohort study during 2 consecutive bronchiolitis seasons, from 2004 to 2006. Thirty US emergency departments contributed data. All patients were < 2 years of age and had a final emergency department attending physician diagnosis of bronchiolitis. Using multivariate logistic regression, a low-risk model was developed with a random half of the data and then validated with the other half. RESULTS Of 1456 enrolled patients, 837 (57%) were discharged home from the emergency department. The following factors predicted safe discharge to home: age of > or = 2 months, no history of intubation, a history of eczema, age-specific respiratory rates (< 45 breaths per minute for 0-1.9 months, < 43 breaths per minute for 2-5.9 months, and < 40 breaths per minute for 6-23.9 months), no/mild retractions, initial oxygen saturation of > or = 94%, fewer albuterol or epinephrine treatments in the first hour, and adequate oral intake. The importance of each factor varied slightly according to age, but the comprehensive model (developed and validated for all children < 2 years of age) yielded an area under the receiver operating characteristic curve of 0.81, with a good fit of the data. CONCLUSIONS This large multicenter study of children presenting to the emergency department with bronchiolitis identified several factors associated with safe discharge, including cut points for respiratory rate and oxygen saturation. Although the low-risk model requires further study, we believe that it will assist clinicians evaluating children with bronchiolitis and may help reduce some unnecessary hospitalizations.

Abstract
OBJECTIVE In 1996, the American Academy of Pediatrics published practice parameters for the acute management of febrile seizure. These guidelines emphasize the typically benign nature of the condition and discourage aggressive neurodiagnostic evaluation. The extent to which these suggestions have been adopted by general emergency medicine practitioners is unknown. We sought to describe recent patterns of the emergency department (ED) evaluation of febrile seizures with respect to these parameters. METHODS A retrospective review of records of children between 6 month and 6 years of age diagnosed with "febrile seizure" (International Classification of Diseases, Ninth Revision, Clinical Modification 780.31) at 42 community hospital general EDs nationwide was performed. Electronic records of an ED physician billing service from October 2002 to September 2003 were used to identify relevant records. Data had been entered into a proprietary template documentation system, and all charts were reviewed by a professional coder blinded to outcomes of interest. Rates of resource utilization (including lumbar puncture, radiography, hospital admission) were noted. RESULTS A total of 1029 charts met inclusion criteria. The overall rate of lumbar puncture was 5.2%, and variations were strongly associated with age (8.4% <18 months old vs 3.3% >18 months old). This low rate and age discrimination were consistent with the guidelines of the American Academy of Pediatrics. Although not recommended in the routine evaluation of febrile seizure, computed tomography was part of the evaluation in 11%. The overall rate of admissions or transfers was 12%. CONCLUSIONS Six years after publication of practice parameters, the use of lumbar puncture in the evaluation of febrile seizure is uncommon and most patients are discharged home. However, the relatively frequent use of head computed tomography is inconsistent with these practice guidelines and merits further investigation.

Abstract
INTRODUCTION Research into childhood attendance at EDs in the UK has focused mainly on injury rather than medical conditions and studies have been relatively small. This study looks at all types of ED attendance by children across a large population. DATA AND METHODS Routine data on all new attendances by children under 16 years were available for 12 EDs in the West Midlands (period: 1 April 2002 to 31 March 2004, 365 695 records). The data were split into four age groups (<1, 1-4, 5-9, and 10-15 years). RESULTS Injury related conditions increased with age (with the exception of head injury). Respiratory and gastrointestinal were the most common medical conditions decreased with age. 11.5% of children were admitted to hospital and this varied from 8.2% (10-15 years) to 24.2% (<1 year). CONCLUSIONS This study has shown substantial variations in ED attendance by age and has given an insight into the variation among hospitals. This is the largest study of childhood ED attendance undertaken in the UK, and it is hoped that the questions raised will prompt more research in this field.

Abstract
Upper and lower respiratory infections are encountered commonly in the emergency department. Visits resulting from occurrences of respiratory disease account for 10% of all pediatric emergency department visits and 20% of all pediatric hospital admissions. Causes of upper airway infections include croup, epiglottitis, retropharyngeal abscess, cellulitis, pharyngitis, and peritonsillar abscesses. Lower airway viral and bacterial infections cause illnesses such as pneumonia and bronchiolitis. Signs and symptoms of upper and lower airway infections overlap, but the differentiation is important for appropriate treatment of these conditions. This article reviews the varied clinical characteristics of upper and lower airway infections.

Abstract
OBJECTIVE Hypoxia is a common reason for hospital admission in infants and children with acute bronchiolitis. No study has evaluated discharge from the emergency department (ED) on home oxygen. This study evaluated the feasibility and safety of ED discharge on home oxygen in the treatment of acute bronchiolitis. METHODS This was a prospective, randomized trial of infants and children with acute bronchiolitis and hypoxia (room-air saturations of < or =87%) aged 2 to 24 months presenting to an urban, academic, tertiary care children's hospital ED from December 1998 to April 2001. Subjects received inpatient admission or home oxygen after an 8-hour observation period in the ED. We measured the failure to meet discharge criteria during the observation period, return for hospital admission, and incidence of serious complications. RESULTS Ninety-two patients were enrolled. Fifty three (58%) were randomly assigned to home and 39 (42%) to inpatient admission. There were no differences between the groups in age, initial room-air saturation, and respiratory distress severity score. Of 53 patients, 37 (70%) randomly assigned to home oxygen completed the observation period and were discharged from the hospital. The remaining 16 patients were excluded from the study (6), resolved their oxygen requirement (5), or failed to meet the discharge criteria and were admitted (5). One discharged patient (2.7%) returned to the hospital and was admitted for a cyanotic spell at home after the 24-hour follow-up appointment. The patient had an uncomplicated hospital course with a length of stay of 45 hours. The remaining 36 patients (97%) were treated successfully as outpatients with home oxygen. Satisfaction with home oxygen was high from the caregiver and the primary care provider. CONCLUSIONS Discharge from the ED on home oxygen after a period of observation is an option for patients with acute bronchiolitis. Secondary to the low incidence of complications, the safety of this practice will require a larger study.

Abstract
BACKGROUND In an attempt to reduce the burden of influenza-like illness (ILI) on health resources, the Italian Ministry of Health released clinical practice guidelines (CPGs) on ILI management that include specific indications for the admission of children to the hospital. The aim of this study was to evaluate whether application of these CPGs reduced the rate of inappropriate hospital admissions. METHODS In the first phase, 2 independent observers recorded the number and clinical condition of children presenting with ILI to the emergency department (ED) of a large urban pediatric hospital and the main reasons for hospital admission. The latter were compared with the CPG indications for hospital admission to evaluate appropriateness. One year later (phase 2), we recorded the number of children with ILI admitted to the hospital by pediatricians trained in a 3-hour course on CPGs and by "untrained" control pediatricians. RESULTS In phase 1 of the study, 854 children accessed the ED; 318 (37.2%) had ILI. Of the latter, 26.2% were admitted to the hospital, and 33.7% of admissions were inappropriate according to CPG criteria. In phase 2, 16% of the children with ILI were admitted by CPG-trained pediatricians and 25.8% by control pediatricians. The number of inappropriate hospital admissions was higher among control than among CPG-trained pediatricians. CONCLUSIONS ILI in children is associated with a high rate of inappropriate hospital admissions. Training of ED pediatricians in the application of a specific CPG may result in a substantial decrease of the admission rate and of inappropriate admissions.
