Abstract
The Saudi Initiative for Asthma 2024 (SINA-2024) is the sixth version of asthma guidelines for the diagnosis and management of asthma for adults and children that was developed by the SINA group, a subsidiary of the Saudi Thoracic Society. The main objective of the SINA is to have guidelines that are up-to-date, simple to understand, and easy to use by healthcare workers dealing with asthma patients. To facilitate achieving the goals of asthma management, the SINA Panel approach is mainly based on the assessment of symptom control and risk for both adults and children. The approach to asthma management is aligned for age groups: adults, adolescents, children aged 5-12 years, and children aged <5 years. SINA guidelines have focused more on personalized approaches reflecting a better understanding of disease heterogeneity with the integration of recommendations related to biologic agents, evidence-based updates on treatment, and the role of immunotherapy in management. The medication appendix has also been updated with the addition of recent evidence, new indications for existing medication, and new medications. The guidelines are constructed based on the available evidence, local literature, and the current situation at national and regional levels. There is also an emphasis on patient-doctor partnership in the management that also includes a self-management plan.

[PMID: 35943201 PMCID: PMC10027615 DOI: 10.1080/02770903.2022.2111686] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 07/29/2022] [Accepted: 08/07/2022] [Indexed: 10/15/2022]
Abstract
OBJECTIVE Severe asthma exacerbations account for a large share of asthma morbidity, mortality, and costs. Here, we aim to identify early predictive factors associated with pediatric intensive care unit (PICU) admission. METHODS We performed a retrospective observational study of 5,185 emergency department (ED) encounters at a large children's hospital, including 86 (1.7%) resulting in PICU admission between 10/1/2015 and 8/7/2018 with ICD9/ICD10 codes for "asthma," "bronchospasm," or "wheezing." Vital signs and demographic information were obtained from electronic health record data and analyzed for each encounter. Predictive factors were identified using adjusted regression models, and our primary outcome was PICU admission. RESULTS Higher mean heart rates (HRs) and respiratory rates (RRs), and lower SpO2 within the first hour of ED presentation were independently associated with PICU admission. Odds of PICU admission increased 70% for each 10 beats/min higher HR, 125% for each 10 breaths/min higher RR, and 34% for each 5% lower SpO2. A binary predictive index using 1-h vitals yielded OR 13.4 (95% CI 8.1-22.1) for PICU admission, area under receiver operator characteristic (AUROC) curve 0.84 and overall accuracy of 80.1%. Results were largely unchanged (AUROC 0.84-0.88) after adjusting for surrogates of asthma severity and initial ED management. In combination with a secondary standardized clinical asthma distress score, positive predictive value increased by sevenfold (6.1%-46%). CONCLUSIONS A predictive index using HR, RR, and SpO2 within the first hour of ED presentation accurately predicted PICU admission in this cohort. Automated vital signs trend analysis may help identify vulnerable patients quickly upon presentation.

Abstract
OBJECTIVE There is a lack of objective measures to assess children with acute wheezing episodes. Increased respiratory rate (RR) and pulsus paradoxus (PP) are recognised markers, but poorly recorded in practice. We examined whether they can be reliably assessed from a pulse oximeter plethysmogram ('pleth') trace and predict clinical outcome. PATIENTS AND METHODS We studied 44 children aged 1-7 years attending hospital with acute wheeze, following initial 'burst' bronchodilator therapy (BT), and used custom software to measure RR and assess PP from oximeter pleth traces. Traces were examined for quality, and the accuracy of the RR measurement was validated against simultaneous respiratory inductive plethysmography (RIP). RR and PP at 1 hour after BT were compared with clinical outcomes. RESULTS RR from pleth and RIP showed excellent agreement, with a mean difference (RIP minus pleth) of -0.5 breaths per minute (limits of agreement -3.4 to +2.3). 52% of 1 min epochs contained 10 s or more of pleth artefact. At 1 hour after BT, children who subsequently required intravenous bronchodilators had significantly higher RR (median (IQR) 63 (62-66) vs 43 (37-51) breaths per minute) than those who did not, but their heart rate and oxygen saturation were similar. Children with RR ≥55 per minute spent longer in hospital: median (IQR) 30 (22-45) vs 10 (7-21) hours. All children who subsequently required hospital admission had PP-analogous pleth waveforms 1 hour after BT. CONCLUSION RR can be reliably measured and PP detected from the pulse oximeter pleth trace in children with acute wheeze and both markers predict clinical outcome.

Abstract
BACKGROUND Asthma is a leading cause of pediatric hospitalization in the United States. Children hospitalized with asthma are often managed in different care settings during hospitalization, posing challenges to accurate communication among care providers about illness severity. Our objective was to study the feasibility, reliability, and safety of a new pediatric hospital-wide asthma severity score (HASS) across different care units within a single tertiary-care pediatric center. METHODS 150 patients between the ages of 2 and 18 years hospitalized with a principal diagnosis of status asthmaticus were included in this study. Study patients were followed from the time of initial triage in the emergency department until the time of medical readiness for discharge. Rates of medical errors, early transfers to a higher level of care and medically indicated hospital length of stay (LOS) were compared between 75 patients before and 75 patients after widespread implementation of the HASS using retrospective chart review and anonymous staff reporting. Interrater reliability was determined by collecting independent HASS scores from blinded staff members after tandem or simultaneous patient assessment. RESULTS Interrater reliability among untrained staff members using the HASS was high. Hospital LOS, rates of adverse events, medical errors, and early transfer to a higher level of care were not significantly different before and after widespread HASS implementation. CONCLUSION The HASS is a reliable asthma severity tool that can be used throughout hospitalization and among multiple clinical providers to trend clinical progress and optimize communication, particularly during times of care handoffs.

Abstract
BACKGROUND In chronic asthma treatment, leukotriene receptor antagonists have been recommended, but it is not clear whether montelukast can be used in acute recurrent wheezing attacks in children. OBJECTIVE To investigate the safety and effectiveness of oral montelukast in addition to standard treatment in hospitalized children aged between 6 and 72 months with acute recurrent wheezing attacks. METHOD One hundred patients aged between 6 and 72 months who had wheezing attacks with clinical asthma scores (CAS) ≥3 and were hospitalized were included in this randomized, double-blind, placebo-controlled, parallel-group clinical trial. All the patients included in the study were given 0.15 mg/kg (maximum 5 mg) nebulized salbutamol (8 L/min and with 100% O2 ) with 4 h of intervals, 1 mg/kg prednisolone (maximum 5 days), nebulized ipratropium bromide (total eight doses) with 6 h of intervals. In addition to this treatment, one group received 4 mg montelukast, and the other group received a placebo. The CAS of the patients were evaluated with 4-h intervals. RESULTS Total hospital length of stay (LOS) was not different between the montelukast and placebo groups (p = 0.981). There was no statistically significant difference between the two treatment groups in terms of discharge time, CAS, and oxygen saturation (p ≥ 0.05). CONCLUSION Adding montelukast to standard treatment in patients hospitalized for moderate-to-severe wheezing attacks did not affect hospital LOS and CAS.

Abstract
Background Asthma is the most common chronic disease of childhood and a major source of childhood health burden worldwide. These burdens are particularly marked when children experience characteristic ‘symptom flare-ups’ or acute asthma exacerbations (AAEs). AAE are associated with significant health and economic impacts, including acute Emergency Department visits, occasional hospitalizations, and rarely, death. To treat children with AAE, several medications have been studied and used. Methods We conducted a narrative review of the literature with the primary objective of understanding the evidence of their efficacy. We present this efficacy evidence in the context of a general stepwise management pathway for paediatric AAEs. This framework is developed from the combined recommendations of eight established (inter)national paediatric guidelines. Discussion Management of paediatric AAE centres around four major care goals: (1) immediate and objective assessment of AAE severity; (2) prompt and effective medical interventions to decrease respiratory distress and improve oxygenation; (3) appropriate disposition of patient; and (4) safe discharge plans. Several medications are currently recommended with varying efficacies, including heliox, systemic corticosteroids, first-line bronchodilators (salbutamol/albuterol), adjunctive bronchodilators (ipratropium bromide, magnesium sulfate) and second-line bronchodilators (aminophylline, i.v. salbutamol, i.v. terbutaline, epinephrine, ketamine). Care of children with AAE is further enhanced using clinical severity scoring, pathway-driven care and after-event discharge planning. Conclusions AAEs in children are primarily managed by medications supported by a growing body of literature. Continued efforts to study the efficacy of second-line bronchodilators, integrate AAE management with long-term asthma control and provide fair/equitable care are required.

Abstract
Asthma is the most common chronic illness in children, with >700,000 emergency department (ED) visits each year. Asthma is a respiratory disease characterized by a combination of airway inflammation, bronchoconstriction, bronchial hyperresponsiveness, and variable outflow obstruction, with clinical presentations ranging from mild to life-threatening. Standardized ED treatment can improve patient outcomes, including fewer hospital admissions. Informed by the most recent guidelines, this review focuses on the optimal approach to diagnosis and treatment of children with acute asthma exacerbations who present to the ED.

Nurse-driven Clinical Pathway Based on an Innovative Asthma Score Reduces Admission Time for Children. Pediatr Qual Saf 2020; 5:e344.

Abstract
We recently demonstrated that an innovative asthma score independent of auscultation could accurately predict the requirement for bronchodilator nebulization compared to the physician's routine clinical judgment to administer bronchodilators. We aimed to standardize inpatient care for children with acute asthma by implementing a clinical pathway based on this innovative asthma score. Methods We designed a nurse-driven clinical pathway. This pathway included standardized respiratory assessments and a protocol for the nursing staff to administer bronchodilators without a specific order from the physician. We compared the length of stay and the number of readmissions to a historical cohort. Results Seventy-nine patients with moderate acute asthma completed the pathway. We obtained a total of 858 Childhood asthma scores in these patients, with a median of 11 scores per patient (interquartile range 8-17). Patients treated according to the nurse-driven protocol were 3.3 times more likely to be discharged earlier (hazard ratio, 3.29; 95% confidence interval, 2.33-4.66; P < 0.05), and length of stay was significantly reduced (median 28 versus 53 h) compared to the historical standard practice. On request, the attending physician assessed the patient's respiratory status 42 times (4.9% of all childhood asthma score assessments). Patient safety was not compromised, and none of the patients were removed from the pathway. In each group, we readmitted two (2.5%) patients within 1 week after discharge. Conclusion This nurse-driven clinical pathway for children with acute asthma based on an asthma score independent of auscultation findings significantly decreased length of stay without compromising patient safety.

Abstract
BACKGROUND Asthma is an illness that commonly affects adults and children, and it serves as a common reason for children to attend emergency departments. An asthma exacerbation is characterised by acute or subacute worsening of shortness of breath, cough, wheezing, and chest tightness and may be triggered by viral respiratory infection, poor compliance with usual medication, a change in the weather, or exposure to allergens or irritants. Most children with asthma have mild or moderate exacerbations and respond well to first-line therapy (inhaled short-acting beta-agonists and systemic corticosteroids). However, the best treatment for the small proportion of seriously ill children who do not respond to first-line therapy is not well understood. Currently, a large number of treatment options are available and there is wide variation in management. OBJECTIVES Main objective - To summarise Cochrane Reviews with or without meta-analyses of randomised controlled trials on the efficacy and safety of second-line treatment for children with acute exacerbations of asthma (i.e. after first-line treatments, titrated oxygen delivery, and administration of intermittent inhaled short-acting beta2-agonists and oral corticosteroids have been tried and have failed) Secondary objectives - To identify gaps in the current evidence base that will inform recommendations for future research and subsequent Cochrane Reviews - To categorise information on reported outcome measures used in trials of escalation of treatment for acute exacerbations of asthma in children, and to make recommendations for development and reporting of standard outcomes in future trials and reviews - To identify relevant randomised controlled trials that have been published since the date of publication of each included review METHODS: We included Cochrane Reviews assessing interventions for children with acute exacerbations of asthma. We searched the Cochrane Database of Systematic Reviews. The search is current to 28 December 2019. We also identified trials that were potentially eligible for, but were not currently included in, published reviews. We assessed the quality of included reviews using the ROBIS criteria (tool used to assess risk of bias in systematic reviews). We presented an evidence synthesis of data from reviews alongside an evidence map of clinical trials. Primary outcomes were length of stay, hospital admission, intensive care unit admission, and adverse effects. We summarised all findings in the text and reported data for each outcome in 'Additional tables'. MAIN RESULTS We identified 17 potentially eligible Cochrane Reviews but extracted data from, and rated the quality of, 13 reviews that reported results for children alone. We excluded four reviews as one did not include any randomised controlled trials (RCTs), one did not provide subgroup data for children, and the last two had been updated and replaced by subsequent reviews. The 13 reviews included 67 trials; the number of trials in each review ranged from a single trial up to 27 trials. The vast majority of comparisons included between one and three trials, involving fewer than 100 participants. The total number of participants included in reviews ranged from 40 to 2630. All studies included children; 16 (24%) included children younger than two years of age. Most of the reviews reported search dates older than four years. We have summarised the published evidence as outlined in Cochrane Reviews. Key findings, in terms of our primary outcomes, are that (1) intravenous magnesium sulfate was the only intervention shown to reduce hospital length of stay (high-certainty evidence); (2) no evidence suggested that any intervention reduced the risk of intensive care admission (low- to very low-certainty evidence); (3) the risk of hospital admission was reduced by the addition of inhaled anticholinergic agents to inhaled beta2-agonists (moderate-certainty evidence), the use of intravenous magnesium sulfate (high-certainty evidence), and the use of inhaled heliox (low-certainty evidence); (4) the addition of inhaled magnesium sulfate to usual bronchodilator therapy appears to reduce serious adverse events during hospital admission (moderate-certainty evidence); (5) aminophylline increased vomiting compared to placebo (moderate-certainty evidence) and increased nausea and nausea/vomiting compared to intravenous beta2-agonists (low-certainty evidence); and (6) the addition of anticholinergic therapy to short-acting beta2-agonists appeared to reduce the risk of nausea (high-certainty evidence) and tremor (moderate-certainty evidence) but not vomiting (low-certainty evidence). We considered 4 of the 13 reviews to be at high risk of bias based on the ROBIS framework. In all cases, this was due to concerns regarding identification and selection of studies. The certainty of evidence varied widely (by review and also by outcome) and ranged from very low to high. AUTHORS' CONCLUSIONS This overview provides the most up-to-date evidence on interventions for escalation of therapy for acute exacerbations of asthma in children from Cochrane Reviews of randomised controlled trials. A vast majority of comparisons involved between one and three trials and fewer than 100 participants, making it difficult to assess the balance between benefits and potential harms. Due to the lack of comparative studies between various treatment options, we are unable to make firm practice recommendations. Intravenous magnesium sulfate appears to reduce both hospital length of stay and the risk of hospital admission. Hospital admission is also reduced with the addition of inhaled anticholinergic agents to inhaled beta2-agonists. However, further research is required to determine which patients are most likely to benefit from these therapies. Due to the relatively rare incidence of acute severe paediatric asthma, multi-centre research will be required to generate high-quality evidence. A number of existing Cochrane Reviews should be updated, and we recommend that a new review be conducted on the use of high-flow nasal oxygen therapy. Important priorities include development of an internationally agreed core outcome set for future trials in acute severe asthma exacerbations and determination of clinically important differences in these outcomes, which can then inform adequately powered future trials.

Abstract
Background Ferguson’s δ and Gini coefficient (GC) are defined as contrasting statistical measures of inequality among members within populations. However, the association and cutting points for these two statistics are still unclear; a visual display is required to inspect their similarities and differences. Methods A simulation study was conducted to illustrate the pertinent properties of these statistics, along with Cronbach’s α and dimension coefficient (DC) to assess inequality. We manipulated datasets containing four item lengths with two number combinations (0 and 33%) in item length if two domains exist. Each item difficulty with five-point polytomous responses was uniformly distributed across a ± 2 logit range. A simulated response questionnaire was designed along with known different structures of true person scores under Rasch model conditions. This was done for 20 normally distributed sample sizes. A total of 320 scenarios were administered. Four coefficients (Ferguson’s δ, GC, test reliability Cronbach’s α, and DC) were simultaneously calculated for each simulation dataset. Box plots were drawn to examine which of these presented the correct property of inequality on data. Two examples were illustrated to present the index on Google Maps for securing the discriminatory power of individuals. Results We found that 1-Ferguson’s δ coefficient has a high correlation (0.95) with GC. The cutting points of Ferguson’s δ, GC, test reliability Cronbach’s α, and the DC are 0.15, 0.50, 0.70, and 0.67, respectively. Two applications are shown on Google Maps with GCs of 0.14 and 0.42, respectively. Histogram legends and Lorenz curves are used to display the results. Conclusion The GC is recommended to readers as an index for measuring the extent of inequality (or lower discrimination power) in a given dataset. It can also show the study results of person measures to determine the inequality in the health-related quality of life outcomes.

J Asthma 2019; 58:151-159. [PMID: 31608716 DOI: 10.1080/02770903.2019.1680998] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/06/2023]
Abstract
Objective: To determine if the Pediatric Asthma Severity Score (PASS) can distinguish "late-rescues" (transfer to the pediatric intensive care unit [PICU] within 24-hours of general pediatric floor admission), "PICU readmissions" (readmission within 24-h after transfer to a lower inpatient level of care), and unplanned 30-day hospital readmission in children admitted with status asthmaticus.Methods: We performed a single center, retrospective cohort study in 328 children admitted for asthma exacerbation aged 5-18 years from May 2015 to October 2017. We sought to determine if PASS values preceding admission from the emergency department or transfer to the general pediatric unit will be greater in children with late rescues and PICU readmissions and if a cutoff PASS values exist to discriminate these events prior to intrafacility transfer.Results: Nine (5%) late-rescues and 5 (3%) PICU readmissions accounted for 14/328 (4%) composite outcomes. PASS values were greater in children with these events (8 [IQR:5-8] vs. 5 [IQR:3-6], p < .01). Logistic regression of PASS on composite outcome yielded an odds ratio of 1.4 (1.1-1.8, p < .01) and ROC curve of PASS on a composite outcome yielded an AUC of 0.74 (0.61-0.87) with a threshold of ≥ 9. Nine (3%) children experienced unplanned 30-day hospital readmissions but PASS preceding hospital discharge was neither discriminative nor associated with hospital readmission.Conclusions: PASS values ≥ 9 identify children at increased risk for late-rescue and PICU readmission. Applied with traditionally criteria for selection of inpatient level of care, PASS may assist providers in reducing acute inpatient disposition errors.

Abstract
This is the fourth version of the updated guidelines for the diagnosis and management of asthma, developed by the Saudi Initiative for Asthma (SINA) group, a subsidiary of the Saudi Thoracic Society. The main objective of the SINA is to have guidelines that are up to date, simple to understand, and easy to use by healthcare workers dealing with asthma patients. To facilitate achieving the goals of asthma management, the SINA panel approach is mainly based on the assessment of symptom control and risk for both adults and children. The approach to asthma management is now more aligned for different age groups. The guidelines have focused more on personalized approaches reflecting better understanding of disease heterogeneity with integration of recommendations related to biologic agents, evidence-based updates on treatment, and role of immunotherapy in management. The medication appendix has also been updated with the addition of recent evidence, new indications for existing medication, and new medications. The guidelines are constructed based on the available evidence, local literature, and current situation at national and regional levels. There is also an emphasis on patient–doctor partnership in the management that also includes a self-management plan.

Abstract
INTRODUCTION There are countless clinical respiratory scales for acute dyspnoea. Most healthcare professionals choose one based on previous personal experience or following local practice, unaware of the implications of their choice. The lack of critical comparisons between those different tools has been a widespread problem that only recently has begun to be addressed via score validation studies. Here we try to assess and compare the quality criteria of measurement properties of acute dyspnoea scores. Areas covered: A literature review was conducted by searching the PubMed database. Forty-five documents were deemed eligible as they reported the use or building of clinical scales, using at least two parameters, and applied these to an acute episode of respiratory dyspnoea. Our primary focus was the description of the validity, reliability and utility of 41 suitable scoring instruments. Differences in sample selection, study design, rater profiles and potential methodological shortcomings were also addressed. Expert commentary: All acute dyspnoea scores lack complete validation. In particular, the areas of measurement error and interpretability have not been addressed correctly by any of the tools reviewed. Frequent modification of pre-existing scores (in items composition and/or name), differences in study design and discrepancies in reviewed sources also hinder the search for an adequate tool.

Abstract
OBJECTIVE Appropriate delivery of Emergency Department (ED) treatment to children with acute asthma requires clinician assessment of acute asthma severity. Various clinical scoring instruments exist to standardize assessment of acute asthma severity in the ED, but their selection remains arbitrary due to few published direct comparisons of their properties. Our objective was to test the feasibility of directly comparing properties of multiple scoring instruments in a pediatric ED. METHODS Using a novel approach supported by a composite data collection form, clinicians categorized elements of five scoring instruments before and after initial treatment for 48 patients 2-18 years of age with acute asthma seen at the ED of a tertiary care pediatric hospital ED from August to December 2014. Scoring instruments were compared for inter-rater reliability between clinician types and their ability to predict hospitalization. RESULTS Inter-rater reliability between clinician types was not different between instruments at any point and was lower (weighted kappa range 0.21-0.55) than values reported elsewhere. Predictive ability of most instruments for hospitalization was higher after treatment than before treatment (p < 0.05) and may vary between instruments after treatment (p = 0.054). CONCLUSIONS We demonstrate the feasibility of comparing multiple clinical scoring instruments simultaneously in ED clinical practice. Scoring instruments had higher predictive ability for hospitalization after treatment than before treatment and may differ in their predictive ability after initial treatment. Definitive conclusions about the best instrument or meaningful comparison between instruments will require a study with a larger sample size.

[PMID: 27329145 DOI: 10.1016/j.alit.2016.05.008] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2015] [Revised: 05/02/2016] [Accepted: 05/07/2016] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND This study was done to compare the efficacy of a recently developed eosinophil-derived neurotoxin (EDN) ELISA kit ("BioTracer™ K® EDN ELISA Kit") to a commercially available EDN ELISA kit ("MBL EDN ELISA Kit") and demonstrate the usefulness of serum EDN measurement in young asthmatic children. METHODS Forty-eight children with physician-diagnosed asthma (Asthma group) and 31 age-matched normal controls (Control group) were recruited from the Asthma and Allergy Center at Inje University Sanggye Paik Hospital, Seoul, Korea from January 2010 to September of 2012. EDN levels in each serum specimen were measured 2 times using the: 1) BioTracer™ K® EDN ELISA Kit and 2) MBL EDN ELISA Kit at the Inje University Sanggye Paik Hospital laboratory. EDN level measurements in each serum specimen were compared. RESULTS EDN measurements from the BioTracer™ K® EDN ELISA Kit correlated well with those from the MBL EDN ELISA Kit: r = 0.9472 at the Inje University Sanggye Paik Hospital laboratory. These r values were considered both clinically relevant (i.e., r > 0.85) and statistically significant (p < 0.0001). EDN measurements from both kits positively correlated with asthma symptom severity (p < 0.0001). No serious adverse events occurred during the study. CONCLUSIONS The BioTracer™ K® EDN ELISA Kit was accurate and useful in measuring EDN levels in young asthma patient serum. Because of our kit's distinct advantages and utility, we suggest this kit can be used for the timely diagnosis, treatment, and monitoring of asthma in asthma patients of all ages, especially those too young to perform pulmonary function tests.

Abstract
BACKGROUND Asthma triggers >775 000 emergency department (ED) visits for children each year. Approximately 80% of these visits occur in community EDs. We performed this study to measure effects of partnership with a community ED on pediatric asthma care. METHODS For this quality improvement initiative, we implemented an evidence-based pediatric asthma guideline in a community ED. We included patients whose clinical impression in the medical decision section of the electronic health record contained the words asthma, bronchospasm, or wheezing. We reviewed charts of included patients 12 months before guideline implementation (August 2012-July 2013) and 19 months after guideline implementation (August 2013-February 2015). Process measures included the proportion of children who had an asthma score recorded, the proportion who received steroids, and time to steroid administration. The outcome measure was the proportion of children who needed transfer for additional care. RESULTS In total, 724 patients were included, 289 during the baseline period and 435 after guideline implementation. Overall, 64% of patients were assigned an asthma score after guideline implementation. During the baseline period, 60% of patients received steroids during their ED visit, compared with 76% after guideline implementation (odds ratio 2.2; 95% confidence interval, 1.6-3.0). After guideline implementation, the mean time to steroids decreased significantly, from 196 to 105 minutes (P < .001). Significantly fewer patients needed transfer after guideline implementation (10% compared with 14% during the baseline period) (odds ratio 0.63; 95% confidence interval, 0.40-0.99). CONCLUSIONS Our study shows that partnership between a pediatric tertiary care center and a community ED is feasible and can improve pediatric asthma care.

Abstract
BACKGROUND The influence of Mycoplasma pneumoniae (MP) infection on bronchiolitis remains unclear. Additionally, reports on the efficacies of leukotriene receptor antagonists in the treatment of bronchiolitis have been inconclusive. METHODS Children with respiratory syncytial virus (RSV)-induced bronchiolitis were divided into two groups: RSV+MP group and RSV group. Each group was randomly divided into two subgroups: one received routine and placebo treatment, while the other received routine and montelukast treatment for 9 months. The cumulative numbers of wheezing episodes and recurrent respiratory tract infections were recorded. Blood parameters were determined. RESULTS Patients in the RSV+MP group exhibited an older average age, fever, more frequent flaky and patchy shadows in chest X-rays, more frequent extrapulmonary manifestations, and longer hospital stays compared with patients in the RSV group. Additionally, higher baseline blood eosinophil counts, eosinophil cationic protein (ECP), total immunoglobulin E (IgE), interleukin (IL)-4, IL-5, IL-4/interferon-γ ratios, leukotriene (LT) B4, and LTC4, and lower baseline lipoxin A4 (LXA4)/LTB4 ratios were observed in the RSV+MP group compared with the RSV group. Montelukast treatment decreased the cumulative numbers of recurrent wheezing episodes and recurrent respiratory tract infections at 9 and 12 months. This efficacy may be related to the montelukast-induced reductions in peripheral eosinophil counts, ECP and total IgE, as well as the montelukast-dependent recovery in T helper (Th) 1/Th2 balance and LXA4/LTB4 ratios in children with bronchiolitis. CONCLUSIONS RSV bronchiolitis with MP infection was associated with clinical and laboratory features that differed from those of RSV bronchiolitis without MP infection. Add-on therapy with montelukast for 9 months was beneficial for children with bronchiolitis at 9 and 12 months after the initiation of treatment.

Abstract
This is an updated guideline for the diagnosis and management of asthma, developed by the Saudi Initiative for Asthma (SINA) group, a subsidiary of the Saudi Thoracic Society. The main objective of SINA is to have guidelines that are up to date, simple to understand and easy to use by nonasthma specialists, including primary care and general practice physicians. SINA approach is mainly based on symptom control and assessment of risk as it is the ultimate goal of treatment. The new SINA guidelines include updates of acute and chronic asthma management, with more emphasis on the use of asthma control in the management of asthma in adults and children, inclusion of a new medication appendix, and keeping consistency on the management at different age groups. The section on asthma in children is rewritten and expanded where the approach is stratified based on the age. The guidelines are constructed based on the available evidence, local literature, and the current situation in Saudi Arabia. There is also an emphasis on patient-doctor partnership in the management that also includes a self-management plan.

Abstract
BACKGROUND In children with acute dyspnoea, the assessment of severity of dyspnoea and response to treatment is often performed by different professionals, implying that knowledge of the interobserver variation of this clinical assessment is important. OBJECTIVE To determine intraobserver and interobserver variation in clinical assessment of children with dyspnoea. METHODS From September 2009 to September 2010, we recorded a convenience sample of 27 acutely wheezing children (aged 3 months-7 years) in the emergency department of a general teaching hospital in the Netherlands, on video before and after treatment with inhaled bronchodilators. These video recordings were independently assessed by nine observers scoring wheeze, prolonged expiratory phase, retractions, nasal flaring and a general assessment of dyspnoea on a Likert scale (0-10). Assessment was repeated after 2 weeks to evaluate intraobserver variation. RESULTS We analysed 972 observations. Intraobserver reliability was the highest for supraclavicular retractions (κ 0.84) and moderate-to-substantial for other items (κ 0.49-0.65). Interobserver reliability was considerably worse, with κ<0.46 for all items. The smallest detectable change of the dyspnoea score (>3 points) was larger than the minimal important change (<1 point), meaning that in 69% of observations a clinically important change after treatment cannot be distinguished from measurement error. CONCLUSIONS Intraobserver variation is modest, and interobserver variation is large for most clinical findings in children with dyspnoea. The measurement error induced by this variation is too large to distinguish potentially clinically relevant changes in dyspnoea after treatment in two-thirds of observations. The poor interobserver reliability of clinical dyspnoea assessment in children limits its usefulness in clinical practice and research, and highlights the need to use more objective measurements in these patients.

Abstract
BACKGROUND Asthma exacerbations lead to frequent emergency visits and hospitalizations, and are associated with high morbidity and occasionally mortality. New therapeutic strategies are needed. We sought to investigate whether the addition of high-dose inhaled budesonide to standard therapy would shorten the length of stay (LOS) in hospital of children admitted for asthma exacerbations. METHODS The study was designed as a single-center, double-blind, placebo-controlled and parallel-group trial. Children aged 7-72 months and admitted with an asthma exacerbation clinical asthma score (CAS) of between 3 and 9 were allocated to either the budesonide (n = 50) or the placebo (n = 50) group. Hospital LOS was compared between children who received 2 mg/day of budesonide versus placebo in addition to standard management of asthma exacerbation involving oxygen inhalation and β2-agonist, anticholinergic and oral corticosteroid therapy. All patients were assessed every 4 h. Children with a CAS <3, a peripheral oxygen saturation >95% and normal pulmonary function, and those with a symptom-free period of at least 4 h after salbutamol treatment were discharged. RESULTS Total hospital LOS was significantly shorter in the budesonide group than in the placebo group (median: 44 vs. 80 h, respectively; p = 0.01). When compared with placebo, the number of inpatients was significantly less in the budesonide group at all the assessed end points (Kaplan-Meier; p = 0.022). Additionally, nebulized budesonide was found to reduce the overall cost of treatment. CONCLUSION We demonstrated that, for children hospitalized for asthma exacerbations, an additional 2 mg/day of nebulized budesonide significantly reduced hospital LOS as well as the overall cost of treatment.

Maekawa T, Oba MS, Katsunuma T, Ishiguro A, Ohya Y, Nakamura H. Modified pulmonary index score was sufficiently reliable to assess the severity of acute asthma exacerbations in children. Allergol Int 2014; 63:603-7. [PMID: 25249062 DOI: 10.2332/allergolint.13-oa-0681] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2013] [Accepted: 05/25/2014] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND The Modified Pulmonary Index Score (MPIS) was developed as an indicator of the severity of acute asthma in children. The objective of this study is to evaluate the reliability and validity of the MPIS for children with acute asthma, including those five years or younger in age. METHODS We evaluated the inter-rater reliability and internal consistency of the MPIS by having at least two trained physicians and a nurse-each of whom was blinded to the others' scores-simultaneously examine inpatients with asthma exacerbation and rate them according to the MPIS. We also evaluated the intraclass correlation coefficient (ICC), kappa, Cronbach's α and correlations between the MPIS and other indicators associated with asthma severity. RESULTS A total of 25 children (median age, five years; 13 patients were five years or younger in age) were enrolled in this study. The MPIS showed excellent inter-rater reliability (all ages: ICC = 0.95, 95% CI = 0.94-0.97; five years or younger: ICC = 0.93, 95% CI = 0.89-0.96) and good internal consistency (all ages: Cronbach's α = 0.87; five years or younger: Cronbach's α = 0.85). The MPIS showed good correlation with a visual analogue scale assessed by the physicians. CONCLUSIONS The MPIS was a sufficiently reliable assessment tool for children with acute asthma, including those five years or younger in age.

Abstract
AIMS AND OBJECTIVES This study aimed to determine the interobserver reliability between bedside nurses and attending physicians for a paediatric respiratory score as part of an asthma Integrated Care Pathway implementation. BACKGROUND An Integrated Care Pathway is one approach to improving quality of care for children hospitalised with asthma. Prior to implementation of the integrated care pathway, it was necessary to train nursing staff on the use of a respiratory assessment tool and to evaluate the interobserver reliability use of this tool. DESIGN Prospective study using a convenience sample of children hospitalised for a respiratory illness in an academic medical centre. METHODS The respiratory assessment used was the Paediatric Asthma Score. Bedside nurse-attending physician (27 different RNs and three attending paediatric hospitalists) pairs performed 71 simultaneous patient assessments on 20 patients. Intraclass correlation coefficient and kappa statistics were used to assess interobserver reliability. RESULTS The overall intraclass correlation coefficient was nearly perfect where κ = 0·95, 95% CI (0·92, 0·97) and overall kappa for reliability based on clinically relevant score breakpoints was also high with κ = 0·82, 95% CI (0·75, 0·90). The majority of subgroup analyses revealed substantial to almost perfect agreement across a variety of diagnoses, age ranges, and individual score components. CONCLUSIONS Bedside nurses, with support and training from attending physicians, can perform respiratory assessments that agree almost perfectly with those of attending physicians. RELEVANCE TO CLINICAL PRACTICE The use of an Integrated Care Pathway allows for optimal interprofessional collaboration between bedside nurses and attending physicians.

Abstract
BACKGROUND A reliable, valid, and easy-to-use assessment of the degree of wheeze-associated dyspnoea is important to provide individualised treatment for children with acute asthma, wheeze or bronchiolitis. OBJECTIVE To assess validity, reliability, and utility of all available paediatric dyspnoea scores. METHODS Systematic review. We searched Pubmed, Cochrane library, National Guideline Clearinghouse, Embase and Cinahl for eligible studies. We included studies describing the development or use of a score, assessing two or more clinical symptoms and signs, for the assessment of severity of dyspnoea in an acute episode of acute asthma, wheeze or bronchiolitis in children aged 0-18 years. We assessed validity, reliability and utility of the retrieved dyspnoea scores using 15 quality criteria. RESULTS We selected 60 articles describing 36 dyspnoea scores. Fourteen scores were judged unsuitable for clinical use, because of insufficient face validity, use of items unsuitable for children, difficult scoring system or because complex auscultative skills are needed, leaving 22 possibly useful scores. The median number of quality criteria that could be assessed was 7 (range 6-11). The median number of positively rated quality criteria was 3 (range 1-5). Although most scores were easy to use, important deficits were noted in all scores across the three methodological quality domains, in particular relating to reliability and responsiveness. CONCLUSION None of the many dyspnoea scores has been sufficiently validated to allow for clinically meaningful use in children with acute dyspnoea or wheeze. Proper validation of existing scores is warranted to allow paediatric professionals to make a well balanced decision on the use of the dyspnoea score most suitable for their specific purpose.

Abstract
BACKGROUND To evaluate a simplified severity score designed to facilitate decision making in the Emergency Department (ED) regarding hospital admission of young adult patients with acute asthma exacerbation (AAE). METHODS All AAE-related ED encounters during two calendar years of patients aged 17-35 years were retrospectively classified as "mild", "moderate" or "severe", according to vital and readily available signs and symptoms, including pulse rate, presence of respiratory wheezes, rales or prolonged expirium, oxygen saturation, and the use of accessory muscles, measured upon arrival to the ED. All medical records of ED and hospital admissions were reviewed for treatment and outcomes. RESULTS During the study period, 723 AAE-related ED encounters were recorded among 551 asthma patients. Of them, 35.0% were classified as "mild", 37.9% "moderate" and 27.1% "severe". For increasing levels of AAE severity, hospital admission rate increased (11.5%, 42.0%, 61.2%, respectively, p < 0.001). Adjusting for age and sex, odds ratios for hospitalization were 12.2 (95% CI: 7.5-19.9) and 5.6 (95% CI: 3.5-8.9) for the "severe" and "moderate" categories, respectively, compared to the "mild" category. "Mild" asthma patients also had shorter length of hospital stay and none required mechanical ventilation or died during hospitalization. CONCLUSION The simplified asthma severity score requires no additional tests or costs in the ED, and could facilitate the decision of whether to hospitalize or discharge adult AAE patients. Prospective validation of this tool is needed.

Abstract
Children with acute asthma exacerbations frequently present to an emergency department with signs of respiratory distress. The most severe episodes are potentially life-threatening. Effective treatment depends on the accurate and rapid assessment of disease severity at presentation. This statement addresses the assessment, management and disposition of paediatric patients with a known diagnosis of asthma who present with an acute asthma exacerbation, especially preschoolers at high risk for persistent asthma. Guidance includes the assessment of asthma severity, treatment considerations, proper discharge planning, follow-up, and prescription for inhaled corticosteroids to prevent exacerbation and decrease chronic morbidity.

Abstract
OBJECTIVE To determine whether eosinophil-derived neurotoxin (EDN) is a predictive marker of recurrent wheezing episodes in post-respiratory syncytial virus (RSV) bronchiolitis. METHODS EDN levels and recurrent wheezing episodes were serially measured in 200 infants hospitalized with RSV bronchiolitis. RESULTS Serum EDN levels at 3 months correlated significantly with total wheezing episodes at 12 months in the RSV-PLC (n = 71; r = 0.720, p < 0.0001) and RSV-MONT groups (n = 79; r = 0.531, p < 0.001). Positive predictive value of 3-mo EDN level for total wheezing episodes was 57%; negative predictive value, 76%; sensitivity, 72%; specificity, 62%. CONCLUSION EDN levels have predictive value for the development of recurrent wheezing post-RSV bronchiolitis.

Abstract
Asthma is associated with increased levels of eosinophils in tissues, body fluids, and bone marrow. Elevated levels of eosinophil-derived neurotoxin (EDN) and eosinophil cationic protein (ECP) have been noted in asthma patients. Higher levels of EDN and ECP are also associated with exacerbated asthmatic conditions. Thus, EDN, along with ECP, may aid the diagnosis and monitoring of asthma. Several groups have suggested that EDN is more useful than ECP in evaluating disease severity. This may partially be because of the recoverability of EDN (not sticky, 100% recovery rate), as ECP is a sticky and more highly charged protein. In terms of clinical utility, EDN level is a more accurate biomarker than ECP when analyzing the underlying pathophysiology of asthma. As a monitoring tool, EDN has shown good results in children with asthma as well as other allergic diseases. In children too young to fully participate in lung function tests, EDN levels may be useful as an alter native measurement of eosinophilic inflammation. EDN can also be used in adult patients and in multiple specimen types (e.g., serum, sputum, bronchoalveolar lavage fluid, and nasal lavage fluid). These results are repeatable and reproducible. In conclusion, EDN may be a novel biomarker for the diagnosis, treatment, and monitoring of asthma/allergic disease.

Abstract
BACKGROUND Acute asthma is one of the most common medical emergencies in children. Appropriate assessment/treatment and early identification of factors that predict hospitalization are critical for the effective utilization of emergency services. OBJECTIVE To identify risk factors that predict hospitalization and to compare the concordance of the Modified Pulmonary Index Score (MPIS) with the Global Initiative for Asthma (GINA) guideline criteria in terms of attack severity. METHODS The study population was composed of children aged 5-18 years who presented to the Emergency Departments (ED) of the tertiary reference centers of the country within a period of 3 months. Patients were evaluated at the initial presentation and the 1(st) and 4(th) hours. RESULTS Of the 304 patients (median age: 8.0 years [interquartile range: 6.5-9.7]), 51.3% and 19.4% required oral corticosteroids (OCS) and hospitalization, respectively. Attack severity and MPIS were found as predicting factors for hospitalization, but none of the demographic characteristics collected predicted OCS use or hospitalization. Hospitalization status at the 1(st) hour with moderate/severe attack severity showed a sensitivity of 44.1%, specificity of 82.9%, positive predictive value of 38.2%, and negative predictive value of 86.0%; for MPIS ≥ 5, these values were 42.4%, 85.3%, 41.0%, and 86.0%, respectively. Concordance in prediction of hospitalization between the MPIS and the GINA guideline was found to be moderate at the 1(st) hour (κ = 0.577). CONCLUSION Attack severity is a predictive factor for hospitalization in children with acute asthma. Determining attack severity with MPIS and a cut-off value ≥ 5 at the 1(st) hour may help physicians in EDs. Having fewer variables and the ability to calculate a numeric value with MPIS makes it an easy and useful tool in clinical practice.

Abstract
This an updated guidelines for the diagnosis and management of asthma, developed by the Saudi Initiative for Asthma (SINA) group, a subsidiary of the Saudi Thoracic Society. The main objective of SINA is to have updated guidelines, which are simple to understand and easy to use by non-asthma specialists, including primary care and general practice physicians. This new version includes updates of acute and chronic asthma management, with more emphasis on the use of Asthma Control Test in the management of asthma, and a new section on "difficult-to-treat asthma." Further, the section on asthma in children was re-written to cover different aspects in this age group. The SINA panel is a group of Saudi experts with well-respected academic backgrounds and experience in the field of asthma. The guidelines are formatted based on the available evidence, local literature, and the current situation in Saudi Arabia. There was an emphasis on patient-doctor partnership in the management that also includes a self-management plan. The approach adopted by the SINA group is mainly based on disease control as it is the ultimate goal of treatment.

Abstract
BACKGROUND The goals of asthma treatment include preventing recurrent exacerbations. Yet there is no consensus about the terminology for describing or defining "exacerbation" or about how to characterize an episode's severity. OBJECTIVE National Institutes of Health institutes and other federal agencies convened an expert group to propose how asthma exacerbation should be assessed as a standardized asthma outcome in future asthma clinical research studies. METHODS We used comprehensive literature reviews and expert opinion to compile a list of asthma exacerbation outcomes and classified them as either core (required in future studies), supplemental (used according to study aims and standardized), or emerging (requiring validation and standardization). This work was discussed at a National Institutes of Health-organized workshop in March 2010 and finalized in September 2011. RESULTS No dominant definition of "exacerbation" was found. The most widely used definitions included 3 components, all related to treatment, rather than symptoms: (1) systemic use of corticosteroids, (2) asthma-specific emergency department visits or hospitalizations, and (3) use of short-acting β-agonists as quick-relief (sometimes referred to as "rescue" or "reliever") medications. CONCLUSIONS The working group participants propose that the definition of "asthma exacerbation" be "a worsening of asthma requiring the use of systemic corticosteroids to prevent a serious outcome." As core outcomes, they propose inclusion and separate reporting of several essential variables of an exacerbation. Furthermore, they propose the development of a standardized, component-based definition of "exacerbation" with clear thresholds of severity for each component.

Abstract
STUDY OBJECTIVE This study was designed to investigate the possible role of IFN-γ in eosinophil degranulation that occurs during respiratory syncytial virus (RSV) bronchiolitis. METHODS Sixty-seven infants, 2-24 months old and hospitalized with their first episode of acute RSV bronchiolitis, were selected for this study. Eosinophil-active cytokine and chemokine profiles in nasal lavage supernatants taken within the first 48 h of admission were determined by a multiplex bead array system (Luminex). Comparisons were made with control (Control group) subjects (n = 20). RESULTS Nasal IFN-γ levels were significantly higher (P < 0.0001) in RSV bronchiolitis (median = 4.4 pg/ml) infants compared to controls (0.0 pg/ml). IFN-γ levels correlated significantly with the levels of nasal eotaxin (r = 0.566, P < 0.0001), RANTES (r = 0.627, P < 0.0001), GM-CSF (r = 0.849, P < 0.0001), and EDN (r = 0.693, P < 0.001). Nasal interleukin (IL)-4, IL-5, and IL-13 were below sensitivity levels in most RSV bronchiolitis and control subjects. CONCLUSION These results suggest that IFN-γ may play an important role in eosinophilic inflammation in RSV bronchiolitis.

Abstract
BACKGROUND Asthma in the pediatric population imposes a significant burden on the Australian health care system. The lack of a standardized asthma assessment tool is an area that needs to be addressed. OBJECTIVE To validate the pulmonary index score (PIS) against the National Asthma Council Guidelines (NACG) asthma assessment. METHODS The project was approved by The Children's Hospital at Westmead Human Research Ethics Committee. Sixty-five patients aged 1 to 12 years with acute asthma were assessed independently using both the PIS and the NACG on presentation to the emergency department. RESULTS These results indicate that the PIS (1) has high internal consistency (Cronbach α = .835); (2) correlates well with the NACG, with significant differences in PIS values across different NACG severity categories; (3) predicts with good sensitivity (85% for nonmild cases and 88% for severe cases) and specificity (75% for nonmild cases and 77% for severe cases) the various categories of asthma severity according to the NACG; and (4) significantly differs between admitted (mean PIS = 8.4) and nonadmitted (mean PIS = 5.0) patients. CONCLUSION Use of the PIS may provide an objective and standardized approach to the assessment and monitoring of asthma in children.

Abstract
INTRODUCTION Environmental tobacco smoke (ETS) and allergens are risk factors in children with critical status asthmaticus. Genetic studies support that ETS-associated asthma is a special inflammatory entity, causing significant number of hospital admissions and relapses. Accordingly, the course and outcome of patients with ETS-induced status asthmaticus might also be different. HYPOTHESIS We hypothesized that the progression, course, and outcome of patients with ETS-induced status asthmaticus would be worse than those of patients without ETS exposure. METHODS Medical records of children who were admitted to the Pediatric Intensive Care Unit (PICU) with the diagnosis of asthma at the Children's Hospital of Winnipeg, Manitoba, over 10 years were audited after Institutional Review Board (IRB) approval. Two hundred thirty records were reviewed. We extracted data including demographics and analyzed the patient's deterioration defined as clinical asthma score (CAS) drift between the ED and PICU. We computed the treatment response, expressed as length of stay (LOS) in the PICU and in hospital. The risk factors were stratified as none, ETS exposure, allergies, and ETS with allergies. RESULTS There were 55 (25%) patients with no risk factors, 66 (30%) with ETS exposure only, 46 (21%) with allergies only, and 53 (24%) with both. There was a 25% decrease in CAS deterioration when patients were exposed to ETS (P < 0.05). For patients with or without allergies but with exposure to ETS, both the PICU and overall hospital LOS were ∼15% longer (P < 0.05) than for those not exposed to ETS. Stratifying for gender and race in multivariate analysis did not alter the results. CONCLUSIONS Patients with ETS-associated critical status asthmaticus deteriorate and recover slower than non-ETS-exposed patients.

Abstract
BACKGROUND Eosinophil numbers and eosinophil cationic protein (ECP) levels have been proposed as markers of disease activity; however, the usefulness of eosinophil-derived neurotoxin (EDN)--another eosinophil granular protein--as a marker in pediatric asthma has not been established. OBJECTIVE The authors compared the concentrations of blood eosinophil counts (TECs), serum ECP, and serum EDN to asthma symptom severity in young children. METHODS Forty-three young children with asthma (Asthma group: mean age, 2.9 years; range, 1.4-5.0 years) were evaluated during both the acute and stable phases of disease. Asthma severity was measured using a symptom-scoring technique, and serum eosinophil indices (EDN and ECP levels and TECs) were determined. Nineteen age-matched controls (Control group: mean age, 2.7 years; range, 1.0-5.0 years) were used for comparison. RESULTS Levels of serum EDN, serum ECP, and TECs were significantly higher in children with acute asthma compared with Controls (p < .0001). However, in stable asthma only EDN and ECP levels differed significantly when compared to Controls (p < .0001 and p < .001, respectively). When comparing acute and stable phases, EDN and TECs differed significantly (p < .0001), whereas ECP did not. Symptom scores correlated significantly with EDN (r = 0.850, p < 0.0001), ECP (r = 0.374, p < 0.01) and TECs (r = 0.457, p < 0.01) in acute asthma patients. When symptom scores were divided into three subgroups based on severity, only EDN levels showed significant differences amongst the three groups. CONCLUSION These findings suggest that serum EDN is a useful marker for identifying disease activity in children with asthma. EDN levels may better reflect disease severity than ECP levels or total eosinophil counts.

Abstract
OBJECTIVES The objective was to evaluate the discriminatory ability of two clinical asthma scores, the Preschool Respiratory Assessment Measure (PRAM) and the Pediatric Asthma Severity Score (PASS), during an asthma exacerbation. METHODS This was a prospective cohort study in an academic pediatric emergency department (ED; 60,000 visits/year) conducted from March 2006 to October 2007. All patients 18 months to 7 years of age who presented for an asthma exacerbation were eligible. The primary outcome was a length of stay (LOS) of >6 hours in the ED or admission to the hospital. Clinical findings and components of the PRAM and the PASS were assessed by a respiratory therapist (RT) at the start of the ED visit and after 90 minutes of treatment. RESULTS During the study period, 3,845 patients were seen in the ED for an asthma exacerbation. Of these, 291 were approached to participate, and eight refused. Moderate levels of discrimination were found between a LOS of >6 hours and/or admission and PRAM (area under the receiver-operating characteristic curve [AUC] = 0.69, 95% confidence interval [CI] = 0.59 to 0.79) and PASS (AUC = 0.70, 95% CI = 0.60 to 0.80) as calculated at the start of the ED visit. Significant similar correlations were seen between the physician's judgment of severity and PRAM (r = 0.54, 95% CI = 0.42 to 0.65) and PASS (r = 0.55, 95% CI = 0.43 to 0.65). CONCLUSIONS The PRAM and PASS clinical asthma scores appear to be measures of asthma severity in children with discriminative properties.

Abstract
OBJECTIVE To investigate the effect of montelukast on eosinophil degranulation and recurrent wheezing episodes in post-respiratory syncytial virus (RSV) bronchiolitis. STUDY DESIGN Two hundred infants (age, 6-24 months) who were hospitalized with their first episode of acute RSV bronchiolitis were randomized in a double-blind, placebo-controlled, parallel comparison of 4-mg montelukast granules (RSV-MONT group) or matching placebo (RSV-PLC group) administered for 3 months. Serum eosinophil-derived neurotoxin (EDN) levels were measured (primary outcome), and recurrent wheezing was documented (secondary outcome) for 12 months. Comparisons were made with control subjects (control group, n = 50). RESULTS At the end of the 3-month treatment period, the RSV-PLC group (n = 71) exhibited significantly elevated EDN levels (P < .0001), and the RSV-MONT group (n = 79) showed significantly decreased EDN levels (P < .01) when compared with the initial levels. As a result, EDN levels in the 2 RSV groups significantly differed at this point (P < .0001) and remained different for the entire 12-month follow-up period. Cumulative recurrent wheezing episodes at 12 months were significantly lower in the RSV-MONT group (P = .039). CONCLUSION Montelukast treatment reduces eosinophil degranulation and is associated with a decrease in recurrent wheezing episodes in post-RSV bronchiolitis.

Abstract
INTRODUCTION Adverse outcomes following clinical deterioration in children admitted to hospital wards is frequently preventable. Identification of children for referral to critical care experts remains problematic. Our objective was to develop and validate a simple bedside score to quantify severity of illness in hospitalized children. METHODS A case-control design was used to evaluate 11 candidate items and identify a pragmatic score for routine bedside use. Case-patients were urgently admitted to the intensive care unit (ICU). Control-patients had no 'code blue', ICU admission or care restrictions. Validation was performed using two prospectively collected datasets. RESULTS Data from 60 case and 120 control-patients was obtained. Four out of eleven candidate-items were removed. The seven-item Bedside Paediatric Early Warning System (PEWS) score ranges from 0-26. The mean maximum scores were 10.1 in case-patients and 3.4 in control-patients. The area under the receiver operating characteristics curve was 0.91, compared with 0.84 for the retrospective nurse-rating of patient risk for near or actual cardiopulmonary arrest. At a score of 8 the sensitivity and specificity were 82% and 93%, respectively. The score increased over 24 hours preceding urgent paediatric intensive care unit (PICU) admission (P < 0.0001). In 436 urgent consultations, the Bedside PEWS score was higher in patients admitted to the ICU than patients who were not admitted (P < 0.0001). CONCLUSIONS We developed and performed the initial validation of the Bedside PEWS score. This 7-item score can quantify severity of illness in hospitalized children and identify critically ill children with at least one hours notice. Prospective validation in other populations is required before clinical application.

Abstract
Care providers for children with bronchiolitis use various tools to evaluate respiratory status. The use of a single tool by different types of care provider requires a high level of inter-observer agreement, an aspect rarely studied. This study, involving 82 physicians, nurses, and respiratory therapists aimed to evaluate inter-observer agreement for clinical evaluations in children hospitalized for a first episode of bronchiolitis. Respiratory evaluation included three frequently reported parameters of respiratory status: respiratory rate, retraction signs, and wheezing. The frequency of concordance for observers from the same and from different care provider groups was assessed using a weighted kappa statistic and considering all possible combinations of care providers. We also calculated inter-provider agreement as a function of patient age, regardless of care provider type. Overall inter-observer agreement for all provider pairs was 93.1%, with a weighted kappa statistic of 0.72 (95% CI, 0.66-0.78), indicating substantial agreement, with no difference as a function of pair composition. Inter-observer agreements for the various age groups ranged from 87% to 93%, with kappa scores ranging from 0.62 to 0.78. We conclude that a simple clinical evaluation for respiratory status assessment has a high level of inter-observer agreement within and between physicians, nurses and respiratory therapists. Thus, once the validity of this test has been confirmed in a large population sample, it should be possible to use this test to monitor children hospitalized with bronchiolitis and as an endpoint in clinical trials.

Abstract
OBJECTIVES This preliminary investigation represents the first step in developing a clinical decision rule (CDR) to assist out-of-hospital providers in caring for older patients in respiratory distress. The specific aims of the study were: 1) to identify up to ten candidate clinical indicators of severe respiratory distress in older out-of-hospital patients and 2) to determine the feasibility of obtaining data on these indicators from out-of-hospital treatment records, and of obtaining a measure of severe respiratory distress from the emergency department (ED) medical record. METHODS This mixed-methods study included a qualitative component to list possible clinical indicators of severe respiratory distress, and a Delphi survey N = six experts) to reduce the comprehensive list that resulted (aim 1). The feasibility of gathering clinical indicators and a measure of severe distress was evaluated using a retrospective chart review (N = 640) of out-of-hospital and ED medical records (aim 2). RESULTS Nine clinical indicators were identified: level of consciousness/mentation, inability to speak in full sentences, position of the patient on arrival, decreased oxygen saturation, accessory muscle use, dyspnea, increased respiratory effort, altered respiratory rate, and retractions. There were sufficient data available on all indicators except dyspnea and retractions; a measure of severe distress was readily obtained from the ED medical record. CONCLUSION Medical record data were available on seven out-of-hospital clinical indicators and an ED measure of severe distress. Further work needs to be done to refine the operational definitions of the indicators and to standardize the way they are documented in the out-of-hospital medical record.

Abstract
This paper describes the development of a tree-based decision model to predict the severity of pediatric asthma exacerbations in the emergency department (ED) at 2 h following triage. The model was constructed from retrospective patient data abstracted from the ED charts. The original data was preprocessed to eliminate questionable patient records and to normalize values of age-dependent clinical attributes. The model uses attributes routinely collected in the ED and provides predictions even for incomplete observations. Its performance was verified on independent validating data (split-sample validation) where it demonstrated AUC (area under ROC curve) of 0.83, sensitivity of 84%, specificity of 71% and the Brier score of 0.18. The model is intended to supplement an asthma clinical practice guideline, however, it can be also used as a stand-alone decision tool.

In very young infants severity of acute bronchiolitis depends on carried viruses. PLoS One 2009; 4:e4596.

Abstract
Background RT amplification reaction has revealed that various single viruses or viral co-infections caused acute bronchiolitis in infants, and RV appeared to have a growing involvement in early respiratory diseases. Because remaining controversial, the objective was to determine prospectively the respective role of RSV, RV, hMPV and co-infections on the severity of acute bronchiolitis in very young infants. Methods and Principal Findings 209 infants (median age: 2.4 months) were enrolled in a prospective study of infants <1 year old, hospitalized for a first episode of bronchiolitis during the winter epidemic season and with no high risk for severe disease. The severity was assessed by recording SaO2% at admission, a daily clinical score (scale 0–18), the duration of oxygen supplementation and the length of hospitalization. Viruses were identified in 94.7% by RT amplification reaction: RSV only (45.8%), RV only (7.2%), hMPV only (3.8%), dual RSV/RV (14.3%), and other virus only (2%) or coinfections (9%). RV compared respectively with RSV and dual RSV/RV infection caused a significant less severe disease with a lower clinical score (5[3.2–6] vs. 6[4–8], p = 0.01 and 5.5[5–7], p = 0.04), a shorter time in oxygen supplementation (0[0–1] days vs. 2[0–3] days, p = 0.02 and 2[0–3] days, p = 0.03) and a shorter hospital stay (3[3–4.7] days vs.6 [5–8] days, p = 0.001 and 5[4–6] days, p = 0.04). Conversely, RSV infants had also longer duration of hospitalization in comparison with RSV/RV (p = 0.01) and hMPV (p = 0.04). The multivariate analyses showed that the type of virus carried was independently associated with the duration of hospitalization. Conclusion This study underlined the role of RV in early respiratory diseases, as frequently carried by young infants with a first acute bronchiolitis. RSV caused the more severe disease and conversely RV the lesser severity. No additional effect of dual RSV/RV infection was observed on the severity.

Abstract
OBJECTIVE The aim of this pilot study was to assess whether long standing asthma affects growth in prepubertal Egyptian children before initiation of long-term corticosteroid therapy. METHODS Children with asthma were divided into two groups according to asthma severity, moderate (n=24) and severe (n=14) and were compared for their physical and skeletal growth with a control group (n=15) using standard deviation score (SDS) and one-way ANOVA (analysis of variance) test. RESULTS No statistically significant differences were found between various growth parameters (weight, height, BMI, upper segment lower segment ratio, and skin fold thickness in asthmatic and normal children, although a positive correlation was found between the age at which the asthma presented and the height in all asthmatic children, r= 0.288, p= 0.036. The bone age standard deviation scores (SDS) were 0.97 mean, -0.165 and -0.572 for controls, moderate and severe asthmatics respectively (P< 0.05), and significant inter group difference between the 2 asthmatic groups (moderate and severe) and the controls was found. CONCLUSION The authors conclude that there was no significant major effect of asthma per se on growth parameters in children, but that skeletal maturation was influenced by long standing asthma.

Abstract
Status asthmaticus (SA) in the pediatric ICU (PICU) can progress to a life-threatening emergency. The goal of management is to improve hypoxemia, improve bronchoconstriction, and decrease airway edema through the administration of continuous nebulized beta2 adrenergic agonist with intermittent anticholinergics, corticosteroids, and oxygen. Adjunctive therapies, such as magnesium, methylxanthines, intravenous beta-agonists, heliox, and noninvasive ventilation should be considered in the child who fails to respond to initial therapies. The restoration of adequate pulmonary functions, resolution of airway obstruction, and avoidance of mechanical ventilation should guide management. This article reviews the pathophysiology, assessment, and management of the child who has SA in the PICU to provide the critical care nurse with current information to facilitate optimal care.

Abstract
The aim of this study was to investigate whether the changes that occurred in the clinical asthma score (CAS) correlated with the changes in the respiratory electromyographic (EMG) activity over the days during admission to hospital in dyspneic infants and toddlers. Sixteen infants and toddlers (9 males) were studied during admission and 7 days after discharge. The CAS was used to assess the severity of dyspnea and consists of five items: respiration rate, wheezing, retractions, observed dyspnea, and inspiration-to-expiration ratio. Each item was scaled 0, 1, or 2, with a maximum score of 10. Electrical activity from the diaphragm (di) and intercostal muscles (int) was derived from surface electrodes. The logarithm of the EMG-Activity-Ratio (log EMGAR; ratio of mean peak-to-bottom EMG activity during admission to the hospital, to that at baseline, 7 days after discharge) was used as EMG parameter. For assessing the association between the repeated observations of the CAS and the EMG measurements we used the quantity r2 obtained with analysis of covariance. On the day of admission the patients had a mean CAS of 5.9 +/- 1.2. On the day of discharge the mean CAS decreased significantly to 2.1 +/- 1.6, indicating that the CAS returned to normal values. In line with this observation, a significant decrease in the log EMGARdi and log EMGARint was observed during the stay in the hospital. Over all subjects the correlation coefficient (r) of log EMGARdi versus CAS was 0.71, log EMGARint versus CAS was 0.67, and the mean log EMGAR versus CAS was 0.75 (p < 0.01, for all values). The correlation coefficients of subjects of < or = 1 year seemed to be lower than those of subjects of > 1 year of age (p < 0.01) and female subjects showed higher correlation coefficients than males. This study showed a moderate, but significant, relationship between the changes that occurred in the CAS and the changes in respiratory EMG activity during admission to hospital in dyspneic infants and toddlers. Moreover, the correlation coefficients of the combined leads of the intercostals and diaphragm (mean log EMGAR) were higher than those of the separate leads. The EMG measurements would extend diagnostic possibilities and would provide an objective measure to evaluate the clinical course of the disease and the efficacy of therapy in infants and toddlers with recurrent wheezing disorders.

Abstract
BACKGROUND Several clinical asthma scores have been derived from combinations of physical findings in pediatric asthmatic patients. OBJECTIVE To test the reproducibility and validity of one such score, the Modified Pulmonary Index Score (MPIS), and to evaluate its predictive value in children hospitalized for asthma. METHODS In the MPIS, 6 categories are evaluated: oxygen saturation, accessory muscle use, inspiratory to expiratory flow ratio, degree of wheezing, heart rate, and respiratory rate. For each of these 6 measurements or observations, a score of 0 to 3 is assigned. To evaluate the reproducibility of the MPIS, inpatients with status asthmaticus were examined by an attending physician, nurse, and respiratory therapist who were blinded to the other observers' scores. To evaluate the validity of the MPIS as a scale of severity of illness in asthmatic patients, the score at admission was compared with selected outcomes in the same patients. RESULTS A total of 30 patients participated in this study (mean +/- SD age, 7.6 +/- 5.5 years). Our finding revealed that the MPIS is highly reproducible with a high degree of interrater reliability across caregiver groups (physician to nurse: r = 0.98; 95% confidence interval [CI], >0.96; physician to respiratory therapist: r = 0.95; 95% CI, >0.92; nurse to respiratory therapist: r = 0.94; 95% CI, >0.90). The admission MPIS positively correlated with intensive care unit admission (P < .001), days of continuous albuterol therapy (P = .002), days of supplemental oxygen (P = .002), and length of hospital stay (P = .004). CONCLUSIONS The MPIS is a highly reproducible and valid indicator of severity of illness in children with asthma. To our knowledge, this is the first pediatric clinical asthma score demonstrated to be reproducible across groups of health care professionals who treat pediatric patients with asthma.

Abstract
OBJECTIVE To evaluate the measurement properties of asthma severity scores for use in preschool children. METHODS A Medline search was used to identify published asthma severity scores for use in preschool children. The measurement properties of the scores (item development, reliability, validity, responsiveness, and usability) were evaluated using a published framework. RESULTS Ten asthma severity scores were identified, with 19 different clinical variables used as items. Interrater agreement was assessed by five scores. Only two scores--Clinical Asthma Score (CAS) and Respiratory Distress Assessment Index (RDAI)--reported good agreement based on weighted kappa-statistics (0.64-0.90). Construct validity was reported by the CAS, Clinical Asthma Evaluation Score (CAES), the Clinical Symptom Grading System (CSGS), and the Preschool Respiratory Assessment Measure (PRAM). Correlation coefficients between asthma severity scores and clinical measures (length of stay, drug dosing interval, O2 saturation, health professional assessment, PaO2, PaCO2) ranged from 0.47 to 0.70. Responsiveness was formally demonstrated for two scales (PRAM, CAS). CONCLUSIONS Most asthma severity scales for use in preschool children have been informally developed. Recently developed scores (CAS, PRAM) have more rigorously evaluated their measurement properties. Research is needed to directly compare the asthma severity scores developed for use in preschool children.
