Abstract
OBJECTIVES Our objective was to elicit clinicians' and parents' perspectives about decision-making related to hospitalization for children with bronchiolitis and the use of shared decision-making (SDM) to guide these decisions. METHODS We conducted individual, semistructured interviews with purposively sampled clinicians (pediatric emergency medicine physicians and nurses) at 2 children's hospitals and parents of children age <2 years with bronchiolitis evaluated in the emergency department at 1 hospital. Interviews elicited clinicians' and parents' perspectives on decision-making and SDM for bronchiolitis. We conducted an inductive analysis following the principles of grounded theory until data saturation was reached for both groups. RESULTS We interviewed 24 clinicians (17 physicians, 7 nurses) and 20 parents. Clinicians identified factors in 3 domains that contribute to hospitalization decision-making for children with bronchiolitis: demographics, clinical factors, and social-emotional factors. Although many clinicians supported using SDM for hospitalization decisions, most reported using a clinician-guided decision-making process in practice. Clinicians also identified several barriers to SDM, including the unpredictable course of bronchiolitis, perceptions of parents' preferences for engaging in SDM, and parents' emotions, health literacy, preferred language, and comfort with discharge. Parents wanted the opportunity to express their opinions during decision-making about hospitalization, although they often felt comfortable with the clinician's decision when adequately informed. CONCLUSIONS Although clinicians and parents of children with bronchiolitis are supportive of SDM, most hospitalization decision-making is clinician guided. Future investigation should evaluate how to address barriers and implement SDM in practice, including training clinicians in this SDM approach.

Abstract
OBJECTIVE This study aimed to compare the traditional bulb aspirator with a nasal-oral aspirator in the treatment of bronchiolitis. METHODS This was a single-center, single-blind, randomized controlled trial. Patients with bronchiolitis discharged from the emergency department were randomized to receive a bulb or nasal-oral aspirator for home use.Data regarding return visits, hydration, respiratory relief, parental satisfaction, device preference, and adverse events were gathered using a predistribution questionnaire, diary, poststudy questionnaire, and chart review. RESULTS There was not a statistically significant difference in the rate of unscheduled return visits (bulb vs nasal-oral, 28.2% vs 20.7%; P = 0.26). No difference was seen in hydration or respiratory relief in either the diary or poststudy questionnaire. The nasal-oral aspirator had higher satisfaction rates (bulb vs nasal-oral, 68.8% vs 93.9%; P < 0.01). When asked which device was preferred with regard to all devices ever tried, 57.2% of respondents reported the nasal-oral aspirator. More adverse events were seen with the bulb compared with the nasal-oral aspirator (bulb vs nasal-oral, 50.0% vs 17.5%; P < 0.01). CONCLUSIONS No difference was appreciated between the bulb and nasal-oral aspirators in unscheduled return rates. The nasal-oral aspirator demonstrated higher parental satisfaction and preference rates, and fewer adverse effects compared with the bulb aspirator. Medical providers should have a cost-benefit discussion with caregivers when recommending home aspirators for the treatment of bronchiolitis.Registry ClinicalTrials.gov Identifier: NCT03288857.

Abstract
OBJECTIVE To determine 1-year attributable healthcare costs of bronchiolitis. METHODS Using a population-based matched cohort and incidence-based cost analysis approach, we identified infants <12 months old diagnosed in an emergency department (ED) or hospitalized with bronchiolitis between April 1, 2003 and March 31, 2014. We propensity-score matched infants with and without bronchiolitis on sex, age, income quintile, rurality, co-morbidities, gestational weeks, small-for-gestational-age status and pre-index healthcare cost deciles. We calculated mean attributable 1-year costs using a generalized estimating equation model and stratified costs by age, sex, income quintile, rurality, co-morbidities and prematurity. RESULTS We identified 58,375 infants with bronchiolitis (mean age 154±95 days, 61.3% males, 4.2% with comorbidities). Total 1-year mean bronchiolitis-attributable costs were $4,313 per patient (95%CI: $4,148-4,477), with $2,847 (95%CI: $2,712-2,982) spent on hospitalizations, $610 (95%CI: $594-627) on physician services, $562 (95%CI: $556-567)] on ED visits, $259 (95%CI: $222-297) on other healthcare costs and $35 ($27-42) on drugs. Attributable bronchiolitis costs were $2,765 (95%CI: $2735-2,794) vs $111 (95%CI: $102-121) in the initial 10 days post index date, $4,695 (95%CI: $4,589-4,800) vs $910 (95%CI: $847-973) in the initial 180 days and $1,158 (95%CI: $1,104-1213) vs $639 (95%CI: $599-679) during days 181-360. Mean 1-year bronchiolitis costs were higher in infants <3 months old [$5,536 (95%CI: $5,216-5,856)], those with co-morbidities [$17,530 (95%CI: $14,683-20,377)] and with low birthweight [$5,509 (95%CI: $4,927-6,091)]. CONCLUSIONS Compared to no bronchiolitis, bronchiolitis incurs five-time and two-time higher healthcare costs within the initial and subsequent six-months, respectively. Most expenses occur in the initial 10 days and relate to hospitalization.

Abstract
AIM Bronchiolitis is the leading cause of hospitalisation in infants, but parental experiences have not been well described. This study explored parents' experiences and asked them how they wanted to receive information. METHODS A qualitative study was conducted in a tertiary paediatric hospital in Québec, Canada. It consisted of semi-structured interviews with 15 parents of 13 children with bronchiolitis. The interview guide was constructed by a multidisciplinary team that included a parent. The interviews, which were transcribed verbatim, were conducted until no new themes emerged. RESULTS We interviewed eight mothers, three fathers and two couples for 22-70 minutes: six were carried out in person during the bronchiolitis episode, and seven were phone interviews after a median interval time of 107 days. Parents were very worried about their child's health and their lack of knowledge about bronchiolitis contributed to their anxiety. They found education resources informative, but expressed a strong need for support and reassurance from healthcare teams. The two groups provided similar feedback, regardless of when they were interviewed or whether their child was admitted. CONCLUSION Although bronchiolitis is common in infancy, parental knowledge was low. Standardised educational tools were useful, but insufficient to meet all their needs.

Abstract
IMPORTANCE Little is known about the natural course of oxygen desaturation in acute bronchiolitis. Information on risk factors associated with desaturation as well as the time to desaturation in infants with bronchiolitis could help physicians better treat these infants before deciding whether to hospitalize them. OBJECTIVE To prospectively determine the frequency of desaturation in infants with bronchiolitis, along with the time to desaturation and risk factors associated with desaturation, and to compare infants who were hospitalized with those discharged home and evaluate risk factors for rehospitalization. DESIGN, SETTING, AND PARTICIPANTS This cohort study was conducted during the 2017 to 2018 and 2018 to 2019 respiratory syncytial virus seasons in a tertiary care pediatric emergency department in Switzerland. Included individuals were 239 otherwise-healthy infants aged younger than 1 year, diagnosed with acute bronchiolitis and oxygen saturation of 90% or more on arrival. Data were analyzed from July 2019 to October 2020. EXPOSURES After receiving triage care, study participants admitted to the emergency department were equipped with a pulse oximeter to continuously record oxygen saturation (Spo2 levels), regardless of subsequent hospitalization or discharge home. MAIN OUTCOMES AND MEASURES The primary outcome was desaturation (ie, Spo2 < 90%) during the first 36 hours. RESULTS Of 239 infants enrolled, with a median (interquartile range [IQR]) age of 3.9 (1.5-6.5) months, 116 (48.5%) were boys and desaturation occurred in 165 infants (69.0%). Median (IQR) time to desaturation was 3.6 (1.8-9.4) hours. The rate of desaturation was similar between infants hospitalized and those discharged home (137 of 200 infants [68.5%] vs 28 of 39 infants [71.8%]; difference, -3.3%; 95% CI, -18.8% to 12.2%; P = .85). A more severe initial clinical presentation with moderate or severe retractions was the only independent risk factor associated with desaturation (odds ratio, 2.73; 95% CI, 1.49 to 5.02; P = .001). Of 39 infants discharged home, 22 infants (56.4%) experienced major desaturations. However, infants with desaturations, including those with major desaturations, had rates of rehospitalization similar to those of infants without desaturations (8 of 28 infants [28.5%] vs 3 of 11 infants [27.3%]; difference, 1.2%; 95% CI, -29.9% to 32.5; P > .99). CONCLUSIONS AND RELEVANCE These findings suggest that rates of desaturation in infants with acute bronchiolitis were high and similar between infants who were hospitalized and those discharged home. A more severe initial clinical presentation was the only risk factor associated with desaturation. However, for infants discharged home, desaturation was not a risk factor associated with rehospitalization.

Pharmacotherapy in bronchiolitis at discharge from emergency departments within the Pediatric Emergency Research Networks: a retrospective analysis. THE LANCET CHILD & ADOLESCENT HEALTH 2019; 3:539-547.

Abstract
BACKGROUND Clinical guidelines advise against pharmacotherapy in bronchiolitis. However, little is known about global variation in prescribing practices for bronchiolitis at discharge from emergency departments. We aimed to evaluate global variation in prescribing practice (ie, inhaled salbutamol, or oral or inhaled corticosteroids) for infants with bronchiolitis at discharge from emergency departments. METHODS We did a planned secondary analysis of a multinational, retrospective cohort study of the Pediatric Emergency Research Networks. Previously healthy infants (aged <12 months) who were discharged with bronchiolitis between Jan 1 and Dec 31, 2013 from 38 emergency departments in Australia and New Zealand, Canada, Spain and Portugal, the UK and Ireland, and the USA were included. The primary outcome was pharmacotherapy prescription at discharge from the emergency department. Secondary outcomes were revisits to the emergency department or hospitalisations for bronchiolitis within 21 days of discharge. FINDINGS Of 1566 infants discharged from the emergency department, 317 (20%) were prescribed pharmacotherapy. Corticosteroid prescriptions were infrequent, ranging from 0% (0 of 68 infants) in Spain and Portugal to 6% (25 of 452) in the USA. Salbutamol prescriptions ranged from 5% (22 of 432) in the UK and Ireland to 32% (146 of 452) in the USA. Compared with the UK and Ireland, the odds of prescription of pharmacotherapy were increased in Spain and Portugal (odds ratio [OR] 9·22, 95% CI 1·70-49·96), the USA (8·20, 2·79-24·11), Canada (5·17, 1·61-16·67), and Australia and New Zealand (1·21, 0·36-4·10). After adjustment for clustering by site, pharmacotherapy at discharge was associated with older age (per 1 month increase; OR 1·23, 95% CI 1·16-1·30), oxygen saturation (per 1% decrease from 100%; 1·09, 1·01-1·18), chest retractions (1·88, 1·26-2·79), network (p=0·00050), and site (p<0·00090). 303 (19%) of 1566 infants returned to the emergency department and 129 (43%) of 303 were hospitalised. Discharge pharmacotherapy was not associated with revisits (p=0·55) or subsequent hospitalisations (p=0·50). INTERPRETATION Use of ineffective medications in infants with bronchiolitis at discharge from emergency departments is common, with large differences in prescribing practices between countries and emergency departments. Enhanced knowledge translation and deprescribing efforts are needed to optimise and unify the management of bronchiolitis. FUNDING None.

Incidence, characteristics and outcomes of patients that return to Emergency Departments. An integrative review. Australas Emerg Care 2019; 22:47-68.

Abstract
BACKGROUND Unplanned return visits account for up to 5% of Emergency Department presentations in Australia and have been associated with adverse events and increased costs. A large number of studies examine the incidence, characteristics and outcomes of unplanned return visits but few studies examine the reasons for return from a patient perspective. The objective of this integrative review was to determine the incidence, characteristics, outcomes and reasons for unplanned return visits to Emergency Departments. METHOD An integrative literature review design was employed to conduct a structured search of the literature using the databases CINAHL, MEDLINE, PubMed, ProQuest and EMBASE (inception to June 2018). Results were screened using predefined criteria and final studies collated and appraised using a quality assessment tool. RESULTS Fifty-two primary research articles were included in the review. The timeframe used to capture unplanned return visits varied and the incidence ranged between 0.07% and 33%. The majority of patients who return unplanned to the Emergency Department are subsequently discharged (51% and 90%) without an adverse event. CONCLUSION There is no consensus on the timeframe employed to classify unplanned return visits to the Emergency Department and the commonly used 72h lacks evidence. Routine statewide data linkage to capture return visits to other facilities is needed to ensure accurate data about this vulnerable patient group. Further research that focuses on patient and clinician perspectives is required to facilitate the development of local strategies to reduce the incidence of avoidable unplanned return visits.

Abstract
Background Bronchiolitis is the leading cause of hospitalization in children under 2 years of age. Each year in the United States, bronchiolitis results in 287,000 emergency department visits, 32%-40% of which end in hospitalization. Frequently, emergency department disposition decisions (to discharge or hospitalize) are made subjectively because of the lack of evidence and objective criteria for bronchiolitis management, leading to significant practice variation, wasted health care use, and suboptimal outcomes. At present, no operational definition of appropriate hospital admission for emergency department patients with bronchiolitis exists. Yet, such a definition is essential for assessing care quality and building a predictive model to guide and standardize disposition decisions. Our prior work provided a framework of such a definition using 2 concepts, one on safe versus unsafe discharge and another on necessary versus unnecessary hospitalization. Objective The goal of this study was to determine the 2 threshold values used in the 2 concepts, with 1 value per concept. Methods Using Intermountain Healthcare data from 2005-2014, we examined distributions of several relevant attributes of emergency department visits by children under 2 years of age for bronchiolitis. Via a data-driven approach, we determined the 2 threshold values. Results We completed the first operational definition of appropriate hospital admission for emergency department patients with bronchiolitis. Appropriate hospital admissions include actual admissions with exposure to major medical interventions for more than 6 hours, as well as actual emergency department discharges, followed by an emergency department return within 12 hours ending in admission for bronchiolitis. Based on the definition, 0.96% (221/23,125) of the emergency department discharges were deemed unsafe. Moreover, 14.36% (432/3008) of the hospital admissions from the emergency department were deemed unnecessary. Conclusions Our operational definition can define the prediction target for building a predictive model to guide and improve emergency department disposition decisions for bronchiolitis in the future.

Abstract
Bronchiolitis is the most common acute lower respiratory tract infection in infants and the first cause of hospitalization in this age group. Despite it has been studied for over 70 years, its management remains controversial and nowadays the treatment is only supportive. Pediatricians should be well acquainted with the clinical course of the disease. In particular, they should know that the severity of respiratory symptoms peaks between days 3-7 of the disease and dehydration is a key sign to consider for the management. In this review, we will discuss the most controversial points in the management of bronchiolitis according to six evidence-based guidelines, six clinical practice guidelines and five consensus-based reviews.

Predictors of Critical Care and Mortality in Bronchiolitis after Emergency Department Discharge. J Pediatr 2018; 199:217-222.e1. [PMID: 29747934 DOI: 10.1016/j.jpeds.2018.04.010] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2017] [Revised: 04/03/2018] [Accepted: 04/06/2018] [Indexed: 12/28/2022]
Abstract
OBJECTIVES To identify the epidemiologic predictors and stratify the risk of critical care unit (CCU) admission or death in bronchiolitis following emergency department discharge. This information has not yet been explored. STUDY DESIGN A population-based cohort study using Ontario-wide demographic and healthcare databases linked at the individual level. We assessed all infants with bronchiolitis discharged home from all emergency departments in Ontario, Canada, 2003-2014. Targeted information included plausible demographic and clinical predictors of CCU admission/death within 14 days of emergency department discharge. Using multivariable logistic regression analyses, we identified independent predictors of this outcome and stratified the outcome risk by the type of multivariable predictor. RESULTS Of 34 270 study infants, 102 (0.3%) were admitted to CCU or died after discharge. Predictors of CCU admission/death were: comorbidities (OR 5.33; 95% CI 2.82-10.10), younger age [months] (OR 1.47; 95%CI 1.33-1.61), low income (OR 1.53; 95% CI 1.01-2.34), younger gestational age [weeks] (OR 1.14; 95%CI 1.06-1.22), and emergent presentation (Canadian Triage and Acuity Scale 2) at the index visit (OR 1.55, 95% CI 1.03-2.33). The absolute event risk of CCU admission/death in infants with versus without comorbidities were 1.5% versus 0.26%, respectively (P < .001). The odds of these outcomes in infants with comorbidities plus ≥2 other predictors were 25 times higher than in infants without predictors (OR 25.1, 95% CI 11.4-55.3). CONCLUSIONS Infants with comorbidities plus other predictors discharged from the emergency department with bronchiolitis are at considerable risk of subsequent CCU admission and death. These risk factors should augment current clinical and social considerations determining patient disposition.

Abstract
In a prospective cohort of children hospitalized for bronchiolitis, we examined the rate of and characteristics associated with bronchiolitis relapse. Bronchiolitis relapse was documented in 22 (6%) of 391 children, and median time to relapse was 2 (interquartile range, 1-7) days. Relapse occurred more often in males. Prenatal smoking and smoke exposure in the home were also associated with relapse.

Abstract
The American Academy of Pediatrics' clinical practice guideline in bronchiolitis was last updated in 2014 with recommendations to improve care for pediatric patients with bronchiolitis. As most treatments of bronchiolitis are supportive, the guideline minimizes the breadth of treatments previously used and cautions the use of tests and therapies that have a limited evidence base. Emergency physicians must be familiar with the guidelines in order to apply best practices appropriately.

Abstract
Aim Our goal in this study is to evaluate the effectiveness of our oxygen (O2) protocol to reduce length of stay (LOS) for children hospitalized with bronchiolitis. Methods In this retrospective cohort study, the outcomes of children ≤ 24 months old that were admitted with bronchiolitis and placed on the O2 protocol were compared to historical controls. The primary outcome was hospital length of stay. Secondary outcomes were duration of O2 supplementation, rates of pediatric intensive care unit transfer, and readmission. Results Groups were not significantly different in age, gender, and rates of respiratory distress score assessment. Significantly more severely ill patients were in the O2 protocol group. There were no significant differences between control and O2 protocol groups with regard to mean LOS, rates of pediatric intensive care unit transfer, or seven-day readmission rates. By multiple regression analysis, the use of the O2 protocol was associated with a nearly 20% significant decrease in the length of hospitalization (p = 0.030). Conclusion Use of O2 supplementation protocol increased LOS in the more ill patients with bronchiolitis but decreased overall LOS by having a profound effect on patients with mild bronchiolitis.

Abstract
INTRODUCTION Respiratory viruses causing lower respiratory tract infections (LRTIs) are a major cause of hospital admissions in children. Since the course of these infections is unpredictable with potential fast deterioration into respiratory failure, infants are easily admitted to the hospital for observation. The aim of this study was to examine whether systemic inflammatory markers can be used to predict severity of disease in children with respiratory viral infections. METHODS Blood and nasopharyngeal washings from children <3 years of age with viral LRTI attending a hospital were collected within 24 hours (acute) and after 4-6 weeks (recovery). Patients were assigned to a mild (observation only), moderate (supplemental oxygen and/or nasogastric feeding) or severe (mechanical ventilation) group. Linear regression analysis was used to design a prediction rule using plasma levels of C reactive protein (CRP), serum amyloid A (SAA), pentraxin 3 (PTX3), serum amyloid P component and properdin. This rule was tested in a validation cohort. RESULTS One hundred and four children (52% male) were included. A combination of CRP, SAA, PTX3 and properdin was a better indicator of severe disease compared with any of the individual makers and age (69% sensitivity (95% CI 50 to 83), 90% specificity (95% CI 80 to 96)). Validation in 141 patients resulted in 71% sensitivity (95% CI 53 to 85), 87% specificity (95% CI 79 to 92), negative predictive value of 64% (95% CI 47 to 78) and positive predictive value of 90% (95% CI 82 to 95). The prediction rule was not able to identify patients with a mild course of disease. CONCLUSION A combination of CRP, SAA, PTX3 and properdin was able to identify children with a severe course of viral LRTI disease, even in children under 2 months of age. To assess the true impact on clinical management, these results should be validated in a prospective randomised control study.

Abstract
INTRODUCTION Unscheduled reattendances at the paediatric emergency department may contribute to overcrowding, which may increase financial burdens. The objectives of this study were to determine the rate of reattendances and characterise factors influencing these reattendances and hospital admission during the return visits. METHODS Medical records of all patients who attended the emergency department at KK Women's and Children's Hospital, Singapore, from 1 June 2013 to 31 May 2014 were retrospectively reviewed. We collected data on patient demographics, attendance data and clinical characteristics. Planned reattendances, recalled cases, reattendances for unrelated complaints and patients who left without being seen were excluded. A multivariate analysis was conducted to determine the odds ratio of variables associated with hospital admission for reattendances. RESULTS Of 162,566 children, 6,968 (4.3%) returned within 72 hours, and 2,925 (42.0% of reattendance group) were admitted on their return visits. Children more likely to reattend were under three years of age, Chinese, triaged as Priority 2 at the first visit, and were initially diagnosed with respiratory or gastrointestinal conditions. However, children more likely to be admitted on their return visits were over 12 years of age, Malay, had a higher triage acuity or were uptriaged, had the presence of a comorbidity, and were diagnosed with gastrointestinal conditions. CONCLUSION We identified certain subgroups in the population who were more likely to be admitted if they reattended. These findings would help in implementing further research and directing strategies to reduce potentially avoidable reattendances and admissions.

Abstract
Recent publications have established the pulse oxygen saturation (SpO2) threshold of 90% for the hospitalization and discharge of infant patients with bronchiolitis. However, there is no clear recommendation regarding the Emergency Department (ED) observation period necessary before allowing safe home discharge for patients with SpO2 above 90%-92%. Our primary aims were to evaluate the risk factors associated with delayed desaturation in infants with SpO2 ≥ 92% on arrival at the ED as well as the ED observation period necessary before allowing safe home discharge. A secondary aim was to identify the risk factors for ED readmission. Of 581 episodes of bronchiolitis in patients < 1 year old admitted to the ED, only 47 (8%) had SpO2 < 92% on arrival there, although 106 (18%) exhibited a delayed desaturation (to < 92%) during ED observation. Female sex, age < 3 months old, ED readmission, more severe initial clinical presentation, and higher pCO2 level (> 6KPa) were risk factors for delayed desaturation with OR varying from 1.7 to 7.5. In patients < 3 months old, mean desaturation occured later than in older patients [6.0 hours (IQR 3.0–14.0) vs. 3.0 hours (IQR 2.0–6.0), P = 0.0018]. In 95% of patients with a delayed desaturation this decrease occurred within 25 hours for patients < 3 months old and within 11 hours for patients ≥ 3 months old. In patients < 3 months old with respiratory rates above the normal range for their age the desaturation occurred earlier than in patients < 3 months with normal respiratory rates [4.4 hours (IQR 3.0–11.7) vs. 14.6 hours (IQR 7.6–22.2), P = 0.037]. Based on the present study’s results, we propose a five step guide for pediatricians on discharging children with bronchiolitis from the ED. By using the threshold of an 11 hour ED observation period for patients ≥ 3 months old and a 25 hour period for patients < 3 months old we are able to detect 95% of the patients with bronchiolitis who are at risk of delayed desaturation.

Abstract
BACKGROUND In young children, bronchiolitis is the most common illness resulting in hospitalization. For children less than age 2, bronchiolitis incurs an annual total inpatient cost of $1.73 billion. Each year in the United States, 287,000 emergency department (ED) visits occur because of bronchiolitis, with a hospital admission rate of 32%-40%. Due to a lack of evidence and objective criteria for managing bronchiolitis, ED disposition decisions (hospital admission or discharge to home) are often made subjectively, resulting in significant practice variation. Studies reviewing admission need suggest that up to 29% of admissions from the ED are unnecessary. About 6% of ED discharges for bronchiolitis result in ED returns with admission. These inappropriate dispositions waste limited health care resources, increase patient and parental distress, expose patients to iatrogenic risks, and worsen outcomes. Existing clinical guidelines for bronchiolitis offer limited improvement in patient outcomes. Methodological shortcomings include that the guidelines provide no specific thresholds for ED decisions to admit or to discharge, have an insufficient level of detail, and do not account for differences in patient and illness characteristics including co-morbidities. Predictive models are frequently used to complement clinical guidelines, reduce practice variation, and improve clinicians' decision making. Used in real time, predictive models can present objective criteria supported by historical data for an individualized disease management plan and guide admission decisions. However, existing predictive models for ED patients with bronchiolitis have limitations, including low accuracy and the assumption that the actual ED disposition decision was appropriate. To date, no operational definition of appropriate admission exists. No model has been built based on appropriate admissions, which include both actual admissions that were necessary and actual ED discharges that were unsafe. OBJECTIVE The goal of this study is to develop a predictive model to guide appropriate hospital admission for ED patients with bronchiolitis. METHODS This study will: (1) develop an operational definition of appropriate hospital admission for ED patients with bronchiolitis, (2) develop and test the accuracy of a new model to predict appropriate hospital admission for an ED patient with bronchiolitis, and (3) conduct simulations to estimate the impact of using the model on bronchiolitis outcomes. RESULTS We are currently extracting administrative and clinical data from the enterprise data warehouse of an integrated health care system. Our goal is to finish this study by the end of 2019. CONCLUSIONS This study will produce a new predictive model that can be operationalized to guide and improve disposition decisions for ED patients with bronchiolitis. Broad use of the model would reduce iatrogenic risk, patient and parental distress, health care use, and costs and improve outcomes for bronchiolitis patients.

Abstract
OBJECTIVES Bronchiolitis is the leading cause of hospital admission for infants, but few studies have examined management of this condition in community hospital settings. We reviewed the management of children with bronchiolitis presenting to community hospitals in Ontario. METHODS We retrospectively reviewed a consecutive cohort of infants less than 12 months old with bronchiolitis who presented to 28 Ontario community hospitals over a two-year period. Bronchiolitis was defined as first episode of wheezing associated with signs of an upper respiratory tract infection during respiratory syncytial virus season. RESULTS Of 543 eligible children, 161 (29.7%, 95% Confidence Interval (CI) 22.3 to 37.0%) were admitted to hospital. Hospital admission rates varied widely (Interquartile Range 0%-40.3%). Bronchodilator use was widespread in the emergency department (ED) (79.7% of patients, 95% CI 75.0 to 84.5%) and on the inpatient wards (94.4% of patients, 95% CI 90.2 to 98.6%). Salbutamol was the most commonly used bronchodilator. At ED discharge 44.7% (95% CI 37.5 to 51.9%) of patients were prescribed a bronchodilator medication. Approximately one-third of ED patients (30.8%, 95% CI 22.7 to 38.8%), 50.3% (95% CI 37.7 to 63.0%) of inpatients, and 23.5% (95% CI 14.4 to 32.7) of patients discharged from the ED were treated with corticosteroids. The most common investigation obtained was a chest x-ray (60.2% of all children; 95% CI 51.9 to 68.5%). CONCLUSIONS Infants with bronchiolitis receive medications and investigations for which there is little evidence of benefit. This suggests a need for knowledge translation strategies directed to community hospitals.

Abstract
Background Respiratory viral infections follow an unpredictable clinical course in young children ranging from a common cold to respiratory failure. The transition from mild to severe disease occurs rapidly and is difficult to predict. The pathophysiology underlying disease severity has remained elusive. There is an urgent need to better understand the immune response in this disease to come up with biomarkers that may aid clinical decision making. Methods In a prospective study, flow cytometric and genome-wide gene expression analyses were performed on blood samples of 26 children with a diagnosis of severe, moderate or mild Respiratory Syncytial Virus (RSV) infection. Differentially expressed genes were validated using Q-PCR in a second cohort of 80 children during three consecutive winter seasons. FACS analyses were also performed in the second cohort and on recovery samples of severe cases in the first cohort. Results Severe RSV infection was associated with a transient but marked decrease in CD4+ T, CD8+ T, and NK cells in peripheral blood. Gene expression analyses in both cohorts identified Olfactomedin4 (OLFM4) as a fully discriminative marker between children with mild and severe RSV infection, giving a PAM cross-validation error of 0%. Patients with an OLFM4 gene expression level above -7.5 were 6 times more likely to develop severe disease, after correction for age at hospitalization and gestational age. Conclusion By combining genome-wide expression profiling of blood cell subsets with clinically well-annotated samples, OLFM4 was identified as a biomarker for severity of pediatric RSV infection.

Virologic testing in bronchiolitis: does it change management decisions and predict outcomes? Eur J Pediatr 2014; 173:1429-35.

Abstract
UNLABELLED The aim of this study was to evaluate the clinical, therapeutic, laboratory, and radiological differences between respiratory syncytial virus (RSV) and non-RSV bronchiolitis in order to assess if the prior knowledge of viral etiology changed management decisions and would be able to predict outcomes. Medical charts of children <1 year admitted to the emergency department with bronchiolitis during two RSV seasons (2010-2012) were reviewed. We analyzed 221 episodes of bronchiolitis. The percentage of exams performed (95 % confidence interval (CI) 0.74-2.52), abnormal laboratory and radiological findings (95 % CI 0.53-16.89) did not differ between groups. RSV bronchiolitis had a more severe clinical course. However, virologic testing for RSV had low specificity in identifying at-risk patients for hospitalization, longer hospital length of stay, and need of oxygen therapy and nasogastric tube (44, 40, 42, and 35 %, respectively), and while statistically significant, the positive likelihood ratios were only slightly greater than 1. CONCLUSION Although RSV bronchiolitis has a more severe clinical course, virologic testing does not help in management decisions, and at an individual level, as a performance test, it seems insufficient to precisely predict outcomes.

Abstract
BACKGROUND AND OBJECTIVE Bronchiolitis is the leading cause of hospitalization for US infants and is associated with increased risk of childhood asthma. Although studies have shown differences in the presentation and management of asthma across race/ethnicity, it is unclear if such differences are present for bronchiolitis. We examined if racial/ethnic differences exist in the presentation and management of severe bronchiolitis. METHODS We performed a 16-center, prospective cohort study from 2007 to 2010. Children <2 years old hospitalized with a diagnosis of bronchiolitis were included. A structured interview, chart review, and 1-week phone follow-up were completed. Multivariable logistic regression was used to examine the independent association between race/ethnicity and diagnostic imaging, treatment (eg, albuterol, corticosteroids, and continuous positive airway pressure/intubation), management (eg, intensive care unit admission and length of stay), discharge on inhaled corticosteroids, and bronchiolitis relapse. RESULTS Among 2130 patients, 818 (38%) were non-Hispanic white (NHW), 511 (24%) were non-Hispanic black (NHB), and 801 (38%) were Hispanic. Compared with all groups, NHB children were most likely to receive albuterol before admission (odds ratio [OR]: 1.58; 95% confidence interval [CI]: 1.20-2.07) and least likely to receive chest x-rays during hospitalization (OR: 0.66; 95% CI: 0.49-0.90). Hispanic children were most likely to be discharged on inhaled corticosteroids (OR: 1.92; 95% CI: 1.19-3.10). CONCLUSION We observed differences between NHW and minority children regarding preadmission albuterol use, inpatient diagnostic imaging, and prescription of inhaled corticosteroids at discharge, practices that deviate from the American Academy of Pediatrics guidelines. The causes of these differences require further study, but they support implementation of care pathways for severe bronchiolitis.

Abstract
BACKGROUND It is unclear whether the infectious etiology of severe bronchiolitis affects short-term outcomes, such as posthospitalization relapse. We tested the hypothesis that children hospitalized with rhinovirus (RV) bronchiolitis, either as a sole pathogen or in combination with respiratory syncytial virus (RSV), are at increased risk of relapse. METHODS We performed a 16-center, prospective cohort study of hospitalized children age <2 years with bronchiolitis. During the winters of 2007-2010, researchers collected clinical data and nasopharyngeal aspirates from study participants; the aspirates were tested using real-time polymerase chain reaction. The primary outcome was bronchiolitis relapse (urgent bronchiolitis visit or scheduled visit at which additions to the bronchiolitis medications were made) during the 2 weeks after hospital discharge. RESULTS Among 1836 enrolled children with 2-week, follow-up data, the median age was 4 months and 60% were male. Overall, 48% had sole RSV infection, 8% had sole RV infection, and 13% had RSV/RV coinfection. Compared with children with sole RSV infection, and adjusting for 10 demographic and clinical characteristics and clustering of patients within hospitals, children with sole RV infection did not differ in their likelihood of relapse (odds ratio: 0.99; 95% confidence interval: 0.52-1.90; P = 0.98), whereas those with RSV/RV coinfection were more likely to have relapse (odds ratio: 1.54; 95% confidence interval: 1.03-2.30; P = 0.03). CONCLUSIONS In this prospective, multicenter, multiyear study of children hospitalized with bronchiolitis, we found that RSV/RV coinfection was independently associated with a higher likelihood of bronchiolitis relapse. Present data support the concept that the infectious etiology of severe bronchiolitis affects short-term outcomes.

A systematic review of predictive modeling for bronchiolitis. Int J Med Inform 2014; 83:691-714.

Abstract
PURPOSE Bronchiolitis is the most common cause of illness leading to hospitalization in young children. At present, many bronchiolitis management decisions are made subjectively, leading to significant practice variation among hospitals and physicians caring for children with bronchiolitis. To standardize care for bronchiolitis, researchers have proposed various models to predict the disease course to help determine a proper management plan. This paper reviews the existing state of the art of predictive modeling for bronchiolitis. Predictive modeling for respiratory syncytial virus (RSV) infection is covered whenever appropriate, as RSV accounts for about 70% of bronchiolitis cases. METHODS A systematic review was conducted through a PubMed search up to April 25, 2014. The literature on predictive modeling for bronchiolitis was retrieved using a comprehensive search query, which was developed through an iterative process. Search results were limited to human subjects, the English language, and children (birth to 18 years). RESULTS The literature search returned 2312 references in total. After manual review, 168 of these references were determined to be relevant and are discussed in this paper. We identify several limitations and open problems in predictive modeling for bronchiolitis, and provide some preliminary thoughts on how to address them, with the hope to stimulate future research in this domain. CONCLUSIONS Many problems remain open in predictive modeling for bronchiolitis. Future studies will need to address them to achieve optimal predictive models.

Abstract
BACKGROUND Acute lower respiratory tract infection (LRTI) including bronchiolitis, is one of the leading causes of pediatric hospital admissions worldwide. Recent studies have demonstrated that some children with acute bronchiolitis can be successfully managed using home oxygen therapy. AIM To report the impact of a Hospital in The Home Oxygen therapy program (HiTHOx) for selected infants and young children with acute bronchiolitis and other LRTI. FINDINGS The HiTHOx program appears to be a safe model of care for carefully selected infants and young children with acute bronchiolitis and LRTI that reduces the hospital length of stay. CONCLUSIONS The HiTHOx program provides an alternative model of care for infants and young children with acute LRTI. Implementation of models of care similar to that of the HiTHOx program in other pediatric health services may have the potential to create additional bed capacity, at the time of year when it is most needed.

Abstract
BACKGROUND Current tools to predict the severity of respiratory syncytial virus (RSV) infection might be improved by including immunological parameters. We hypothesized that a combination of inflammatory markers would differentiate between severe and mild disease in RSV-infected children. METHODS Blood and nasopharyngeal samples from 52 RSV-infected children were collected during acute infection and after recovery. Retrospectively, patients were categorized into three groups based on disease severity: mild (no supportive treatment), moderate (supplemental oxygen and/or nasogastric feeding), and severe (mechanical ventilation). Clinical data, number of flow-defined leukocyte subsets, and cytokine concentrations were compared. RESULTS Children with severe RSV infection were characterized by young age; lymphocytopenia; increased interleukin (IL)-8, granulocyte colony-stimulating factor (G-CSF), and IL-6 concentrations; and decreased chemokine (C-C motif) ligand (CCL-5) concentrations in plasma. The combination of plasma levels of IL-8 and CCL-5, and CD4+ T-cell counts, with cutoff values of 67 pg/ml, 13 ng/ml, and 2.3 × 10(6)/ml, respectively, discriminated severe from mild RSV infection with 82% sensitivity and 96% specificity. CONCLUSION This study demonstrates that the combination of CD4+ T-cell counts and IL-8 and CCL-5 plasma concentrations correlates with disease severity in RSV-infected children. In addition to clinical features, these immunological markers may be used to assess severity of RSV infection and guide clinical management.

Abstract
Matrix metalloproteinases (MMPs) play an important role in respiratory inflammatory diseases, such as asthma and chronic obstructive pulmonary disease. It was hypothesized that MMP-8 and MMP-9 may function as biological markers to assess disease severity in viral lower respiratory tract infections in children. MMP-8 and MMP-9 mRNA expression levels in peripheral blood mononuclear cells (PBMCs) and granulocytes obtained in both the acute and recovery phase from 153 children with mild, moderate, and severe viral lower respiratory tract infections were determined using real-time PCR. In addition, MMP-8 and MMP-9 concentrations in blood and nasopharyngeal specimens were determined during acute mild, moderate, and severe infection, and after recovery using ELISA. Furthermore, PBMCs and neutrophils obtained from healthy volunteers were stimulated with RSV, LPS (TLR4 agonist), and Pam3Cys (TLR2 agonist) in vitro. Disease severity of viral lower respiratory tract infections in children is associated with increased expression levels of the MMP-8 and MMP-9 genes in both PBMCs and granulocytes. On the contrary, in vitro experiments showed that MMP-8 and MMP-9 mRNA and protein expression in PBMCs and granulocytes is not induced by stimulation with RSV, the most frequent detected virus in young children with viral lower respiratory tract infections. These data indicate that expression levels of the MMP-8 and MMP-9 genes in both PBMCs and neutrophils are associated with viral lower respiratory tract infections disease severity. These observations justify future validation in independent prospective study cohorts of the usefulness of MMP-8 and MMP-9 as potential markers for disease severity in viral respiratory infections.

Abstract
PURPOSE OF REVIEW Bronchiolitis impacts millions of infants worldwide. Although several therapeutic options stem from highly plausible theoretical rationales for success and some may even offer modest short-term symptom relief, none has been conclusively shown to alter the course of the disease or its major outcomes. However, several recent papers shed light on which treatments show promising preliminary evidence and offer insight into future research endeavors on this topic. This review will summarize bronchiolitis therapy in view of this recent evidence. RECENT FINDINGS The agents in which theory promises but treatment does not deliver include systemic corticosteroids alone, inhaled bronchodilators alone and antileukotrienes. The most promising combination to date appears to be that of oral dexamethasone and inhaled epinephrine but numerous related issues need to be clarified further. Caretakers need to be counselled about the usual protracted clinical course of bronchiolitis. SUMMARY Because bronchiolitis is a highly heterogeneous entity, future research challenges should include detailed characterization of infants most likely to benefit from given interventions. In the meantime, stick with the good old time-honored supportive route!
