Abstract
BACKGROUND Respiratory rate is a vital physiological measurement used in the immediate assessment of unwell children and adults. Convenient electronic devices exist for the measurement of pulse, blood pressure, oxygen saturation, and temperature. Although devices which measure respiratory rate exist, none have entered everyday clinical practice for acute assessment of children and adults. An accurate and practical device which has no physical contact with the patient is important to ensure readings are not affected by distress caused by the assessment method. OBJECTIVE The aim of this study was to evaluate the use of a thermal imaging method to monitor the respiratory rate in children and adults. METHODS Facial thermal images of adult volunteers and children undergoing elective polysomnography were included. Respiration was recorded for at least 2 min with the camera positioned 1 m from the subject's face. Values obtained using the thermal imaging camera were compared with those obtained from contact methods such as the nasal thermistor, respiratory inductance plethysmography, nasal airflow, and end tidal CO2. RESULTS A total of 61 subjects, including 41 adults (age range 27-46 years) and 20 children (age range 0.5-18 years) were enrolled. The correlation between the respiratory rate measured using thermal imaging and the contact method was r = 0.94. Sequential refinements to the thermal imaging algorithms resulted in the ability to perform real-time measurements and an improvement of the correlation to r = 0.995. CONCLUSION This exploratory study shows that thermal imaging-derived respiratory rates in children and adults correlate closely with the best performing standard method. With further refinements, this method could be implemented in both acute and chronic care in children and adults.

Abstract
Abstract Introduction: Young children are at high risk of respiratory infections. The severity of the disease is based on the assessment of signs and symptoms, although there is a lack of validated scales to the Portuguese population. Objective: The aim of this study was to accomplish the cultural adaptation and validation of the subjective and objective parameters in paediatric respiratory conditions, according to Postiaux. Methods: We ensured the cultural adaptation of the “Paramètres anamnestiques et cliniques utiles au suivi et à l’achèvement de la toilette bronchopulmonaire du nourrisson et de l’enfant”, created by Guy Postiaux. Then we analysed content, conceptual and construct validity, as well as test-retest reliability. The Portuguese version was applied in a sample of 59 children, with a mean age of 23.05 ± 8.34 months, 55.9% male. Results: We stablished semantics and construct validity and adopted the title “Paediatric Respiratory Severity Score” (PRSS). PRSS obtained a good internal consistency (α de Cronbach = 0.80) and an excellent intra-rater reliability (ICC = 0.91). Subjective parameters revealed a Cronbach’ α = 0.80 and an ICC = 0.90. Objective parameters obtained a Cronbach’ α = 0.73 and an ICC = 0.85. The application of PRSS to the sample showed that 37.3% of the children had a normal health condition (PRSS = 8) and 62.7% of the children had a moderate impairment of their health condition (9 ≤ PRSS ≤ 16). Conclusion: Paediatric Respiratory Severity Score is a valid and reliable measure to assess the severity of acute respiratory infections in children under 36 months of age.

Abstract
OBJECTIVE To determine the inter-observer agreement of a respiratory rate (RR) count on a child when assessed by three independent observers. DESIGN The RR of 169 children (age range: 3 days to 15 years) was measured by three independent observers over a 3-month period. The first RR was taken by different healthcare professionals (HCPs) from within the hospital using their own preferred method of measurement. A further count of RR was then taken by two observers from the research team simultaneously within 30 min of the first measurement, using the WHO-recommended method of measurement. RESULTS 507 RR measurements were taken on 169 children. Median RR showed a 4 beats per minute (bpm) difference between the HCP (median RR 32 bpm) and the researchers (median RR 28 bpm). The 95% limits of agreement between the first measurement and second and third measurements were -10.2 to 17.7 bpm and -11.4 to 18.7 bpm, respectively. For simultaneous measurements, the 95% limits of agreement were -7.1 to 7.0 bpm. 81 children had a RR > 95th centile for their age and an even poorer level of agreement was seen in these children than in those whose RR was within normal range. In only 27 of these 81 children (33%) did all three observers agree on the presence of a raised RR. CONCLUSIONS Inter-observer agreement for the measurement of RR in children is poor. The effect that this variation has on the clinical assessment and subsequent management of a child may be significant. These findings highlight the need for a robust review of our current measurement methods and interpretation of an important vital sign.

Abstract
OBJECTIVE To measure the inter-rater reliability of 7 visual and 3 auscultatory respiratory physical examination findings at 36-40 weeks' postmenstrual age in infants born less than 29 weeks' gestation. Physicians also estimated the probability that each infant would remain hospitalized for 3 months after the examination or be readmitted for a respiratory illness during that time. STUDY DESIGN Prospective, multicenter, inter-rater reliability study using standardized audio-video recordings of respiratory physical examinations. RESULTS We recorded the respiratory physical examination of 30 infants at 2 centers and invited 32 physicians from 9 centers to review the examinations. The intraclass correlation values for physician agreement ranged from 0.73 (95% CI 0.57-0.85) for subcostal retractions to 0.22 (95% CI 0.11-0.41) for expiratory abdominal muscle use. Eight (27%) infants remained hospitalized or were readmitted within 3 months after the examination. The area under the receiver operating characteristic curve for prediction of this outcome was 0.82 (95% CI 0.78-0.86). Physician predictive accuracy was greater for infants receiving supplemental oxygen (0.90, 95% CI 0.86-0.95) compared with those breathing in room air (0.71, 95% CI 0.66-0.75). CONCLUSIONS Physicians often do not agree on respiratory physical examination findings in premature infants. Physician prediction of short-term respiratory morbidity was more accurate for infants receiving supplemental oxygen compared with those breathing in room air.

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
OBJECTIVE High-flow humidified nasal cannula is often used to provide noninvasive respiratory support in children. The effect of high-flow humidified nasal cannula on effort of breathing in children has not been objectively studied, and the mechanism by which respiratory support is provided remains unclear. This study uses an objective measure of effort of breathing (Pressure. Rate Product) to evaluate high-flow humidified nasal cannula in critically ill children. DESIGN Prospective cohort study. SETTING Quaternary care free-standing academic children's hospital. PATIENTS ICU patients younger than 18 years receiving high-flow humidified nasal cannula or whom the medical team planned to extubate to high-flow humidified nasal cannula within 72 hours of enrollment. INTERVENTIONS An esophageal pressure monitoring catheter was placed to measure pleural pressures via a Bicore CP-100 pulmonary mechanics monitor. Change in pleural pressure (ΔPes) and respiratory rate were measured on high-flow humidified nasal cannula at 2, 5, and 8 L/min. ΔPes and respiratory rate were multiplied to generate the Pressure.Rate Product, a well-established objective measure of effort of breathing. Baseline Pes, defined as pleural pressure at end exhalation during tidal breathing, reflected the positive pressure generated on each level of respiratory support. MEASUREMENTS AND MAIN RESULTS Twenty-five patients had measurements on high-flow humidified nasal cannula. Median age was 6.5 months (interquartile range, 1.3-15.5 mo). Median Pressure,Rate Product was lower on high-flow humidified nasal cannula 8 L/min (median, 329 cm H2O·min; interquartile range, 195-402) compared with high-flow humidified nasal cannula 5 L/min (median, 341; interquartile range, 232-475; p = 0.007) or high-flow humidified nasal cannula 2 L/min (median, 421; interquartile range, 233-621; p < 0.0001) and was lower on high-flow humidified nasal cannula 5 L/min compared with high-flow humidified nasal cannula 2 L/min (p = 0.01). Baseline Pes was higher on high-flow humidified nasal cannula 8 L/min than on high-flow humidified nasal cannula 2 L/min (p = 0.03). CONCLUSIONS Increasing flow rates of high-flow humidified nasal cannula decreased effort of breathing in children, with the most significant impact seen from high-flow humidified nasal cannula 2 to 8 L/min. There are likely multiple mechanisms for this clinical effect, including generation of positive pressure and washout of airway dead space.

Abstract
BACKGROUND Hypoxia associated with bronchiolitis is not always easy to assess on clinical grounds alone. The aim of this study was to determine the value of food intake during the previous 24h (bottle and spoon feeding), as a percentage of usual intake (24h FI), as a marker of hypoxia, and to compare its diagnostic value with that of usual clinical signs. METHODS In this observational, prospective, multicenter study, 18 community pediatricians, enrolled 171 infants, aged from 0 to 6 months, with bronchiolitis (rhinorrhea+dyspnea+cough+expiratory sounds). Infants with risk factors (history of prematurity, chronic heart or lung disorders), breast-fed infants, and infants having previously been treated for bronchial disorders were excluded. The 24h FI, subcostal, intercostal, supracostal retractions, nasal flaring, respiratory rate, pauses, cyanosis, rectal temperature and respiratory syncytial virus test results were noted. The highest stable value of transcutaneous oxygen saturation (SpO2) was recorded. Hypoxia was noted if SpO2 was below 95% and verified. RESULTS 24h FI greater or equal to 50% was associated with a 96% likelihood of SpO2 greater or equal to 95% [95% CI, 91-99%]. In univariate analysis, 24h FI less than 50% had the highest odds ratio (13.8) for SpO2 less than 95%, compared to other 24h FI values and other clinical signs, as well as providing one of the best compromises between specificity (90%) and sensitivity (60%) for identifying infants with hypoxia. In multivariate analysis with adjustment for age, SpO2 less than 95% was related to the presence of intercostal retractions (OR=9.1 [95% CI, 2.4-33.8%]) and 24h FI less than 50% (OR=10.9 [95% CI, 3.0-39.1%]). Hospitalization (17 infants) was strongly related to younger age, 24h FI and intercostal retractions. CONCLUSION In practice, the measure of 24h FI may be useful in identifying hypoxia and deserves further study.

Abstract
BACKGROUND Viral laryngotracheobronchitis croup is the most common cause of acute upper airway obstruction in young children. Clinical assessment of children with croup is often performed using 'croup scores'; however, these scores have not been validated outside of the research setting. OBJECTIVE To determine the reliability of clinical observation items in croup scores in a paediatric emergency department (ED) setting. DESIGN Literature review identified 12 observation items (level of consciousness or mental status, inspiratory breath sounds, air entry, stridor, cough, cyanosis or colour, anxiety or air hunger, retractions and/or flaring, respiratory rate and heart rate, oxygen saturation and respiratory distress); overlapping items were combined, yielding 10 variables. In a prospective cohort study over 13 months, patients presenting with croup were observed independently, and croup scores were assigned by the triage nurse, ED nurse and the ED physician before treatment. Agreement among observers for clinical observations was analysed using Cohen's quadratic weighted kappa. SETTING University-affiliated, paediatric hospital ED providing primary care to an urban area (population 330,000). PATIENTS Children aged three months to five years presenting with viral croup (preceding history of at least one day of upper respiratory tract symptoms associated with barking cough and/or hoarseness and/or stridor). RESULTS One hundred fifty-eight children meeting inclusion criteria for croup were assessed by three observers within 1 h of each other's assesments and before treatment. Interobserver agreement among the three observers using weighted kappa was greater than chance for all clinical observation items and ranged from fair to moderate (0.2 to 0.4 and 0.4 to 0.6, respectively). CONCLUSIONS In the busy practice setting of a paediatric ED, substantial interobserver variability exists among health care providers in the measurement of respiratory signs associated with croup in young children. Based on the present study in a practice setting and two research studies, the most reliable items of all of the published items included in croup scoring systems were stridor and retractions.

Abstract
We present a review of the evidence on prognosis of acute bronchiolitis, risk factors for severe forms, symptom or severity scores and risk of post-bronchiolitis asthma. Documented risk factors of long stay or PICU admission in hospitalized patients are: bronchopulmonary dysplasia and/or chronic lung disease, prematurity, congenital heart disease and age less than 3 months. Other less well documented risk factors are: tobacco exposure, history of neonatal mechanical ventilation, breastfeeding for less than 4 months, viral co-infection and other chronic diseases. There are several markers of severity: toxic appearance, tachypnea, hypoxia, atelectasis or infiltrate on chest radiograph, increased breathing effort, signs of dehydration, tachycardia and fever. Although we have some predictive models of severity, none has shown sufficient predictive validity to recommend its use in clinical practice. While there are different symptom or severity scores, none has proven to be valid or accurate enough to recommend their preferable application in clinical practice. There seems to be a consistent and strong association between admission due to bronchiolitis and recurrent episodes of wheezing in the first five years of life. However it is unclear whether this association continues in subsequent years, as there are discordant data on the association between bronchiolitis and asthma.

Abstract
OBJECTIVES To compare the effect of nebulized racemic epinephrine to nebulized racemic albuterol on successful discharge from the emergency department (ED). METHODS Children up to their 18th month of life presenting to two teaching hospital EDs with a clinical diagnosis of bronchiolitis who were ill enough to warrant treatment but did not need immediate intubation were eligible for this double-blind randomized controlled trial (RCT). Patients received either three doses of racemic albuterol or one dose of racemic epinephrine plus two saline nebulizers. Disposition was decided 2 hours after the first nebulizer. Successful discharge was defined as not requiring additional bronchodilators in the ED after study drug administration and not subsequently admitted within 72 hours. Adjusted relative risks (aRR) were estimated using the modified Poisson regression with successful discharge as the dependent variable and study drug and severity of illness as exposures. Secondary analysis was performed for patients aged less than 12 months and first presentation. RESULTS The authors analyzed 703 patients; 352 patients were given albuterol and 351 epinephrine. A total of 173 in the albuterol group and 160 in the epinephrine group were successfully discharged (crude RR = 1.08, 95% confidence interval [CI] = 0.92 to 1.26). When adjusted for severity of illness, patients who received albuterol were significantly more likely than patients receiving epinephrine to be successfully discharged (aRR = 1.18, 95% CI = 1.02 to 1.36). This was also true among those with first presentation and in those less than 12 months of age. CONCLUSIONS In children up to the 18th month of life, ED treatment of bronchiolitis with nebulized racemic albuterol led to more successful discharges than nebulized epinephrine.

Abstract
UNLABELLED Population-based incidence data from Europe on the disease burden of lower respiratory tract infections (LRTI) due to respiratory syncytial viruses (RSV), parainfluenza viruses (PIV) and influenzaviruses (IV) are lacking, especially with respect to the disease burden. In a 2-year prospective multicentre study of children aged <3 years in Germany, we registered population-based cases as outpatients (n=2386), inpatients (n=2924), and nosocomially-acquired (n=141). Nasopharyngeal secretions were tested for viral RNA. The annual incidence for physician visits per 100 children for all LRTI was 28.7, RSV 7.7, PIV 3.8 and IV 1.1. Annual hospitalisation rates per 10(5) children were for all LRTI 2941, RSV 1117, PIV 261 and IV 123. Annual nosocomial cases per 10(5) hospital days were for all LRTI 79, RSV 29, PIV 9 and IV 1.5. All five children (0.27%) who died had an underlying disease and four were nosocomially acquired. CONCLUSION Hospitalisation rates due to lower respiratory tract infections in healthy children were similar to those reported elsewhere; the rates for outpatient visits were approximately ten times higher.

Abstract
OBJECTIVE It is uncertain whether pediatric and general emergency departments have different admitting practices regarding children with bronchiolitis. The objective of this study was to quantify the differences in admission practices between pediatric and general emergency departments of children with bronchiolitis in 1 North American metropolitan area, controlling for various factors such as clinical severity, comorbid conditions, and socioeconomic status. DESIGN Retrospective cohort review of emergency department visits from April 1992 to March 1997. SETTING Five emergency departments (1 pediatric and 4 general) serving the Calgary Health Region, which encompasses approximately 850 000 people. PATIENTS All children residing within the region who visited a regional emergency department and were diagnosed to have bronchiolitis (International Classification of Diseases, Ninth Revision code 466.1, primary or secondary diagnosis). MAIN OUTCOME MEASURE Population-standardized estimates of admission rates. RESULTS The medical charts of 3091 children diagnosed to have bronchiolitis during the study period were reviewed. Of this number, 2496 children were evaluated at the pediatric emergency department, and 629 (25%) were admitted. The remaining 595 (19%) were evaluated at the general emergency departments, and 221 (37%) were admitted. Controlling for age, gender, estimated family income based on postal code, medical comorbidity, and clinical severity estimated by presenting respiratory rate and room air oxygen saturation, population-standardized estimates for admission rates at the pediatric and general emergency departments were 24% (standard error: 1%) and 43% (standard error: 2%), respectively. CONCLUSION Children diagnosed to have bronchiolitis at the Calgary Health Region's pediatric emergency department were about half as likely to be admitted to the hospital as children diagnosed at the region's general emergency departments.

Abstract
Identification of variables that predict duration of RSV-associated hospitalization may be useful in the identification of preventive and therapeutic strategies. A recently published prediction model (Michigan model) for the duration of hospitalization in RSV infection demonstrated good discrimination between children with and without an increased likelihood of a hospital stay >or= 7 days, based on variables such as log weight, congenital heart disease, failure to thrive, premature birth, bronchopulmonary dysplasia, other pulmonary diseases, miscellaneous conditions, early mechanical ventilation, and early ribavirin treatment (receiver operating characteristic (ROC) area, 0.89). Validation of this model is of particular interest for Europe, since the mean duration of hospitalization in The Netherlands is approximately twice that in the USA. The objective of the current study was 1) to validate the Michigan model for RSV hospitalized patients in a large university hospital in The Netherlands, and 2) to develop our own prediction model for a prolonged hospital stay. Data from 177 children younger than 12 months of age admitted with confirmed RSV infection to the Sophia Children's Hospital Rotterdam between 1992-1995, were used for valiation of the Michigan model and derivation of the Rotterdam model. Mean duration of hospitalization for the Rotterdam database was 10.3 (+/-6.3) days, with a median of 9 days; 138 (78%) patients had a hospital stay >or= 7 days. The Michigan model performed poorly when applied to the Rotterdam database, with an ROC area of 0.65 (95% CI, 0.57-0.73). The Rotterdam prediction model (hospital stay >or= 9 days, the median in our database) considered weight and need for oxygen supplementation. The ROC area was 0.65 (95% CI, 0.57-0.73). When using data from patients for the 1995-1996 season, the ROC area was 0.52 (95% CI, 0.34-0.72). The Michigan and the Rotterdam models failed to identify a considerable number of patients who had a prolonged hospital stay, with a low false-positive rate. We conclude that neither the Michigan, nor the Rotterdam model reliably predicted the duration of hospitalization based on demographic and clinical variables.

Abstract
OBJECTIVE To determine nosocomial transmission of respiratory syncytial virus (RSV) in Canadian pediatric hospitals, outcomes associated with nosocomial disease, and infection control practices. DESIGN A prospective cohort study in the 1992 to 1994 winter respiratory seasons. SETTING Nine Canadian pediatric university-affiliated hospitals. PARTICIPANTS Hospitalized children with symptoms of lower respiratory tract infection (at least one of cough, wheezing, dyspnea, tachypnea, and apnea) and RSV antigen identified in a nasopharyngeal aspirate. RESULTS Of 1516 children, 91 (6%) had nosocomial RSV (NRSV), defined as symptoms of lower respiratory tract infection and RSV antigen beginning >72 hours after admission. The nosocomial ratio (NRSV/[com-munity-acquired RSV {CARSV})] + NRSV) varied by site from 2.8% to 13%. The median length of stay attributable to RSV for community-acquired illness was 5 days, but 10 days for nosocomial illness. Four children with NRSV (4. 4%) died within 2 weeks of infection, compared with 6 (0.42%) with CARSV (relative risk = 10.4, 95% confidence interval: 3.0, 36.4). All sites isolated RSV-positive patients in single rooms or cohorted them. In a multivariate model, no particular isolation policy was associated with decreased nosocomial ratio, but gowning to enter the room was associated with increased risk of RSV transmission (incidence rate ratio 2.81; confidence interval: 1.65, 4.77). CONCLUSIONS RSV transmission risk in Canadian pediatric hospitals is generally low. Although use of barrier methods varies, all sites cohort or isolate RSV-positive patients in single rooms. Children with risk factors for severe disease who acquire infection nosocomially have prolonged stays and excess mortality.

Abstract
OBJECTIVES To quantify the cost and distribution of health care resources consumed annually in management of Canadian children from birth to 4 years of age with respiratory syncytial virus (RSV) infection. STUDY DESIGN Estimates of direct medical expenditures (in 1993 U.S. dollars) were collected from a prospective cohort study of hospitalized children with RSV and from national and provincial databases. RESULTS The annual cost of RSV-associated illness was almost $18 million. The largest component of direct expenditures (62%) was for inpatient care for the estimated 0.7% of all infected children ill enough to require admission. Physician fees comprised only 4% of inpatient expenses. Expenditures for ambulatory patients accounted for 38% of direct costs. CONCLUSIONS The greatest reductions in the economic cost of RSV infections will be found in interventions that reduce duration of or prevent hospital stay. Costs for management of RSV infection in children in the Canadian health care system are considerably less than charges reported in the United States.
