RESUMEN
Vitamin D's role in immune system regulation and its contribution to host defenses against respiratory infections may have implications for bronchiolitis pathophysiology. This cross-sectional study aimed to determine the association between the clinical severity of bronchiolitis and serum vitamin D levels in infants. Infants aged 1 month to 12 months, diagnosed with bronchiolitis, and healthy controls attending routine immunization were enrolled. Baseline characteristics were recorded, including clinical details, bronchiolitis severity, and course during hospital stay. Bronchiolitis severity score (BSS) was used to score the severity. A 1-2 ml serum sample was obtained for vitamin D levels estimation. The median age of cases (n = 64; 65.6% male) was 5 [3, 8] months, and that of the control group (n = 30) was 3 [2, 9] months. No statistically significant differences were observed between the two groups in age, gender, weight, mode of delivery, family history of atopy/asthma, feeding pattern, smoke exposure, and daily vitamin D supplementation. The median vitamin D levels were not significantly different between the groups (p = 0.68). Among infants with bronchiolitis, 62.5% had vitamin D insufficiency (≤ 20 ng/ml). A significantly higher median BSS indicates that infants with vitamin D insufficiency exhibited more severe disease (p = 0.019). Although a negative correlation between BSS and vitamin D levels was noted, it did not reach statistical significance [rs = (-)0.17; p = 0.16]. CONCLUSION: Infants with Vitamin D insufficiency experienced more severe bronchiolitis with elevated BSS scores. It highlights the potential role of vitamin D deficiency in severe bronchiolitis. WHAT IS KNOWN: ⢠Vitamin D level is low in infants with bronchiolitis. WHAT IS NEW: ⢠Infant with low vitamin D level experienced more severe bronchiolitis.

Background: Severe acute respiratory infections (SARIs) are the leading cause of paediatric death globally, particularly in low- and middle-income countries (LMICs). Given the potential rapid clinical decompensation and high mortality rate from SARIs, interventions that facilitate the early care are critical to improving patient outcomes. Through this systematic review, we aimed to evaluate the impact of emergency care interventions on improving clinical outcomes of paediatric patients with SARIs in LMICs. Methods: We searched PubMed, Global Health, and Global Index Medicus for peer-reviewed clinical trials or studies with comparator groups published before November 2020. We included all studies which evaluated acute and emergency care interventions on clinical outcomes for children (29 days to 19 years) with SARIs conducted in LMICs. Due to observed heterogeneity of interventions and outcomes, we performed narrative synthesis. We assessed bias using the Risk of Bias 2 and Risk of Bias in Non-Randomized Studies of Interventions tools. Results: We screened 20 583, 99 of which met the inclusion criteria. Conditions studied included pneumonia or acute lower respiratory infection (61.6%) and bronchiolitis (29.3%). Studies evaluated medications (80.8%), respiratory support (14.1%), and supportive care (5%). We found the strongest evidence of benefit for decreasing risk of death for respiratory support interventions. Results were inconclusive on the utility of continuous positive airway pressure (CPAP). We found mixed results for interventions for bronchiolitis, but a possible benefit for hypertonic nebulised saline to decrease hospital length of stay. Early use of adjuvant treatments such as Vitamin A, D, and zinc for pneumonia and bronchiolitis did not appear to have convincing evidence of benefit on clinical outcomes. Conclusions: Despite the high global burden of SARI in paediatric populations, few emergency care (EC) interventions have high quality evidence for benefit on clinical outcomes in LMICs. Respiratory support interventions have the strongest evidence for benefit. Further research on the use of CPAP in diverse settings is needed, as is a stronger evidence base for EC interventions for children with SARI, including metrics on the timing of interventions. Registration: PROSPERO (CRD42020216117).

BACKGROUND: Infant bronchiolitis has a high death rate in severe cases. In China, traditional Chinese medicine (TCM) is commonly used to treat infant bronchiolitis. However, it has not received enough international attention. OBJECTIVE: We aimed to assess the efficacy and safety of integrated TCM and Western medicine for treating infant bronchiolitis. METHODS: We conducted a systematic review through 7 databases that included randomized controlled trials on integrated TCM and Western medicine for treating bronchiolitis, published in English or Chinese before February 4, 2021. To assess the risk of bias, the Cochrane Collaboration tool was employed to determine the quality of the included studies. We investigated clinical efficacy endpoints, hospitalization time, rates of recurrence, and adverse reactions and meta-analyzed the odds ratio (OR), mean difference (MD), and relative risk (RR), respectively. We assessed the overall certainty of the effect estimates using the GRADE approach. This study is registered with PROSPERO (CRD42021245294). Ethical approval is not required. RESULTS: Forty-six studies (6427 children) were available for inclusion. We used 41 (5490 participants), 11 (1350 participants), 5 (1083 participants), and 11 (1295 participants) studies to analyze clinical efficacy endpoints (OR: 3.31; 95% confidence interval [CI]: 2.93, 3.74; P < .5), hospitalization time (MD: -2.10; 95% CI: -2.87, -1.34; P < .5), recurrence rate (RR: 0·41; 95% CI: 0.30, 0.56; P < .01), and adverse reaction rate (RR: 0.87; 95% CI: 0.55, 1.39; P = .57), respectively. CONCLUSIONS: Integrated TCM and Western medicine is superior to Western medicine alone for treating bronchiolitis in terms of clinical efficacy, hospitalization time, and recurrence rate, with no increase in the adverse reaction rate. TCM is useful as an alternative therapy for viral bronchiolitis. Although further studies are needed to establish specific protocols for the use of TCM in clinical practice, these results may strengthen guideline recommendations regarding the use of TCM.

AIM: Bronchiolitis is an infectious disease, with no effective treatment. Music and Mozart's works specifically are known to have a positive effect on physiological parameters, while noise is considered harmful. We aim to evaluate the short-term effect of environmental noise detachment and/or music listening on the course of bronchiolitis in hospitalised children. METHODS: This is a prospective, double-blinded randomised controlled trial. Patients were divided into three intervention groups: 1-Mozart's Sonata, 2-instrumental music, 3-silence. Music was heard via media players and soundproof headphones. Disease severity was evaluated before and after intervention using the Modified Tal score. RESULTS: Seventy music sessions were included in the analysis (Mozart n = 23, instrumental n = 22, silence n = 25). A one-point drop in the average bronchiolitis severity score was observed in all three groups from 7.1 (CI 95%, 5 to 9.2) to 6.1 (CI 95%, 4.3 to 7.9), p < 0.001. No significant difference was found between the three groups with respect to change in the severity score before and after the intervention. CONCLUSION: Isolation from disturbing sounds heard in paediatric departments could be considered a simple non-invasive intervention in children hospitalised with bronchiolitis. Further studies are warranted to evaluate long-term effects of this intervention and the specific effect of music.

BACKGROUND: Bronchiolitis, the most common cause of hospitalization in infancy has not yet a definitive treatment. This study was conducted to assess the effect of Zinc and vitamin D on treatment of infants with bronchiolitis. METHODS: In this double blind, randomized clinical trial, 94 infants aged 2 to 23 months, admitted in Mousavi Hospital in Zanjan, Iran, with the diagnosis of acute bronchiolitis were randomly assigned into 3 groups. The control group was only treated with hypertonic saline. The two case groups received either 100 unit/kg/day of Vitamin D or 20 mg/day of zinc in addition to hypertonic saline. Wheezing, duration of hospital stay, cough, cyanosis, respiratory distress and the respiratory rate in the first, third and seventh day of hospitalization were evaluated. RESULTS: There was no significant difference between groups in terms of age, sex, weight, passive smoking, wheezing, oxygen saturation, cyanosis and type of delivery. On the third day of hospitalization, the respiratory rate/min in the control group, the groups receiving vitamin D and zinc were 45.2 ± 10.7, 37.8 ± 3.9 and 41.1 ± 9.1 respectively and the result of repeated measure analysis didn't show any significant difference between the 3 groups (P = 0.562). Duration of hospitalization in the group receiving Vitamin D or zinc and in controls were 4.2 ± 2.6, 4.4 ± 2.2 and 5.1 ± 2.4 days respectively and this difference was not significant. Zinc receiving patients did not differ from the control group regarding to respiratory rate, cyanosis and wheezing. CONCLUSION: Vitamin D or zinc administration was not effective in reducing respiratory rate in children with bronchiolitis. Trial registration This project was approved by the Institutional Ethics Committee (IR, ZUMS.REC.1396.50), and registered on IRCT (IRCT20131217015835N7).

Exposure to elevated levels of diacetyl in flavoring and microwave popcorn production has been associated with respiratory impairment among workers including from a severe lung disease known as obliterative bronchiolitis. Laboratory studies demonstrate damage to the respiratory tract in rodents exposed to either diacetyl or the related alpha-diketone 2,3-pentanedione. Respiratory tract damage includes the development of obliterative bronchiolitis-like changes in the lungs of rats repeatedly inhaling either diacetyl or 2,3-pentanedione. In one flavored coffee processing facility, current workers who spent time in higher diacetyl and 2,3-pentanedione areas had lower lung function values, while five former flavoring room workers were diagnosed with obliterative bronchiolitis. In that and other coffee roasting and packaging facilities, grinding roasted coffee beans has been identified as contributing to elevated levels of diacetyl and 2,3-pentanedione. To reduce worker exposures, employers can take various actions to control exposures according to the hierarchy of controls. Because elimination or substitution is not applicable to coffee production facilities not using flavorings, use of engineering controls to control exposures at their source is especially important. This work demonstrates the use of temporary ventilated enclosures around grinding equipment in a single coffee roasting and packaging facility to mitigate diacetyl and 2,3-pentanedione emissions from grinding equipment to the main production space. Concentrations of diacetyl and 2,3-pentanedione were measured in various locations throughout the main production space as well as inside and outside of ventilated enclosures to evaluate the effect of the enclosures on exposures. Diacetyl and 2,3-pentanedione concentrations outside one grinder enclosure decreased by 95 and 92%, respectively, despite ground coffee production increasing by 12%, after the enclosure was installed. Outside a second enclosure, diacetyl and 2,3-pentanedione concentrations both decreased 84%, greater than the 33% decrease in ground coffee production after installation. Temporary ventilated enclosures used as engineering control measures in this study effectively reduced emissions of diacetyl and 2,3-pentanedione at the source in this facility. These findings motivated management to explore options with a grinding equipment manufacturer to permanently ventilate their grinders to reduce emissions of diacetyl and 2,3-pentanedione.

Nos lactentes, o sistema imunológico ainda é imaturo, o que torna as crianças mais suscetíveis ao vírus sincicial respiratório, o principal causador da bronquiolite. O Reequilíbrio Toraco-abdominal (RTA) é um método de terapia manual que atua sobre o sistema respiratório por meio de uma leitura global em situações de doenças. Objetivos: Avaliar os efeitos do método RTA, comparado à fisioterapia tradicional (FT) em lactentes com bronquiolite. Metodologia: Pesquisa experimental e prospectiva, na qual 24 lactentes foram divididos em dois grupos, FT (n = 12) e RTA (n = 12). Parâmetros fisiológicos (frequência respiratória, frequência cardíaca, saturação de pulso de oxigênio e ausculta pulmonar), desconforto respiratório e desequilíbrio da biomecânica respiratória foram avaliados antes e após os manuseios. Resultados: A idade média foi de 13 (± 11,07) semanas no grupo FT e no grupo RTA 13,3 (± 8,41) semanas. Após os manuseios, obteve diferença estatística no grupo do RTA comparado ao da FT nos seguintes parâmetros: observamos uma diminuição significativa da frequência cardíaca (p = 0,02) e da frequência respiratória (p = 0,0002), no quesito esforço respiratório em tórax superior (p = 0,004) e tórax inferior (p = 0,017) e no escore de Wood-Downes em moderada com (p = 0,0001). Conclusão: O RTA mostrou-se mais eficaz que as técnicas da FT em relação aos benefícios ao lactente. (AU)

BACKGROUND: Clinicians may be reluctant to feed patients on high-flow nasal cannula (HFNC) therapy, despite studies suggesting it is beneficial and safe. We describe the implementation of a feeding protocol for patients with bronchiolitis on HFNC and determine its effect on nutrition goals. METHODS: Prospective bedside data on enteral volume, feed interruptions, and aspiration events were collected on patients with bronchiolitis who were <24 months of age, treated with HFNC, and fed per a developed protocol. Exclusion criteria included history of prematurity <32 weeks, congenital heart disease, or positive-pressure ventilation before feeding. Length of intensive care unit and hospital stay was compared with both a concurrent cohort (CC) of patients not fed per the protocol and a retrospective cohort (RC) admitted prior to protocol creation. RESULTS: Seventy-eight patients met the criteria for the prospective study arm: 24 patients were included in the CC, and 74 were included in the RC. Seventy-one percent of prospective patients received enteral nutrition (EN) on HFNC day 1 vs 42% of the CC. In the prospective cohort, feed interruption occurred in 23% of patients and was associated with higher flow rates; however, no aspiration events occurred. Patients fed per protocol were fed 8-10 h sooner and discharged 1 day earlier than those in the RC. CONCLUSION: The use of a feeding protocol for patients with bronchiolitis on HFNC was safe and associated with shorter time to initiate EN and shorter length of hospital stay.

BACKGROUND/AIM: Acute bronchiolitis is mostly caused by viral agents in children under 2 years of age. The disease mostly has a mild clinical course however severe cases are not uncommon. Vitamin D is known to exert immune-regulatory functions. We aimed to examine the association between the clinical severity of acute bronchiolitis and serum vitamin D levels in infants. MATERIALS AND METHODS: A total of 182 children with acute bronchiolitis were prospectively enrolled. The disease severity was assessed using the Modified Tal Scoring System and their vitamin D levels were evaluated. RESULTS: Vitamin D deficiency or insufficiency was as high as 47.8% in infants with bronchiolitis. Infants with low vitamin D levels comprised a significantly larger proportion of patients with severe bronchiolitis (p = 0.002). Infants admitted to intensive care unit had significantly higher degrees of vitamin D deficiency or insufficiency (p < 0.001). CONCLUSION: Vitamin D deficiency is closely linked with severe bronchiolitis and the need for intensive care unit admission in infants. We believe that assessment of vitamin D levels in infants prior to bronchiolitis season and appropriate supplementation may have a protective effect against severe bronchiolitis.

OBJECTIVES: To analyze the impact of an integrated care pathway on reducing unnecessary treatments for acute bronchiolitis. METHODS: We implemented an evidence-based integrated care pathway in primary care (PC) centers and the referral emergency department (ED). This is the third quality improvement cycle in the management of acute bronchiolitis implemented by our research team. Family and provider experiences were incorporated by using design thinking methodology. A multifaceted plan that included several quality improvement initiatives was adopted to reduce unnecessary treatments. The primary outcome was the percentage of infants prescribed salbutamol. Secondary outcomes were prescribing rates of other medications. The main control measures were hospitalization and unscheduled return rates. Salbutamol prescribing rate data were plotted on run charts. RESULTS: We included 1768 ED and 1092 PC visits, of which 913 (51.4%) ED visits and 558 (51.1%) PC visits occurred in the postintervention period. Salbutamol use decreased from 7.7% (interquartile range [IQR] 2.8-21.4) to 0% (IQR 0-1.9) in the ED and from 14.1% (IQR 5.8-21.6) to 5% (IQR 2.7-8) in PC centers. In the ED, the overall epinephrine use rate fell from 9% (95% confidence interval [CI], 7.2-11.1) to 4.6% (95% CI, 3.4-6.1) (P < .001). In PC centers, overall corticosteroid and antibiotic prescribing rates fell from 3.5% (95% CI, 2.2-5.4) to 1.1% (95% CI, 0.4-2.3) (P =.007) and from 9.5% (95% CI; 7.3-12.3) to 1.7% (95% CI, 0.9-7.3) (P <.001), respectively. No significant variations were noted in control measures. CONCLUSIONS: An integrated clinical pathway that incorporates the experiences of families and clinicians decreased the use of medications in the management of bronchiolitis.

OBJECTIVE: To investigate the association of serum vitamin D and nasal secretion antimicrobial peptides (AMPs) levels with the severity of acute bronchiolitis. STUDY DESIGN: We conducted a prospective single pediatric tertiary care center cohort study of inpatients aged 0-18 months with a first episode of acute bronchiolitis from November 1st 2014 to April 30th 2017. Disease severity was determined by the length of hospitalization and supplemental hospital data. Qualitative measurements included serum 25(OH)D and nasal secretion LL-37 and ß-defensin-2 levels. Correlations were examined with the Mann-Whitney and Kruskal-Wallis criteria for qualitative and the correlation coefficient Spearman's rho for quantitative factors. Multiple linear and logarithmic regression were performed to adjust for confounding factors. RESULTS: The study population consisted of 153 infants and toddlers with median age 3.1 months (interquartile range:1.6-4.9). No association was found between serum 25(OH)D and AMPs nasal secretions levels. Serum 25(OH)D and nasal secretion ß-defensin-2 levels were not associated with the severity of bronchiolitis. In contrast, LL-37 levels were inversely associated with the length of hospitalization (rho = -0.340, p = .001), the need for medication use (p = .001), as well as the duration of oxygen supplementation (rho = -0.339, p = .001), and intravenous fluid administration (rho = -0.323, p = .001). This association remained significant after adjustment for potential confounders. CONCLUSION: A significant association between LL-37 nasal secretions levels with the severity of acute bronchiolitis was found in hospitalized infants and toddlers. The role of LL-37 in the pathogenesis of bronchiolitis merits further investigation.

BACKGROUND: Acute bronchiolitis is a significant burden on children, their families and healthcare facilities. It mostly affects children younger than two years of age. Treatment involves adequate hydration, humidified oxygen supplementation, and nebulisation of medications, such as salbutamol, epinephrine, and hypertonic saline. The effectiveness of magnesium sulphate for acute bronchiolitis is unclear. OBJECTIVES: To assess the effects of magnesium sulphate in acute bronchiolitis in children up to two years of age. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, LILACS, CINAHL, and two trials registries to 30 April 2020. We contacted trial authors to identify additional studies. We searched conference proceedings and reference lists of retrieved articles. Unpublished and published studies were eligible for inclusion. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs, comparing magnesium sulphate, alone or with another treatment, with placebo or another treatment, in children up to two years old with acute bronchiolitis. Primary outcomes were time to recovery, mortality, and adverse events. Secondary outcomes were duration of hospital stay, clinical severity score at 0 to 24 hours and 25 to 48 hours after treatment, pulmonary function test, hospital readmission within 30 days, duration of mechanical ventilation, and duration of intensive care unit stay. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. We used GRADE methods to assess the certainty of the evidence. MAIN RESULTS: We included four RCTs (564 children). One study received funding from a hospital and one from a university; two studies did not report funding sources. Comparator interventions differed among all four trials. Studies were conducted in Qatar, Turkey, Iran, and India. We assessed two studies to be at an overall low risk of bias, and two to be at unclear risk of bias, overall. The certainty of the evidence for all outcomes and comparisons was very low except for one: hospital re-admission rate within 30 days of discharge for magnesium sulphate versus placebo. None of the studies measured time to recovery, duration of mechanical ventilation, duration of intensive care unit stay, or pulmonary function. There were no events of mortality or adverse effects for magnesium sulphate compared with placebo (1 RCT, 160 children). The effects of magnesium sulphate on clinical severity are uncertain (at 0 to 24 hours: mean difference (MD) on the Wang score 0.13, 95% confidence interval (CI) -0.28 to 0.54; and at 25 to 48 hours: MD on the Wang score -0.42, 95% CI -0.84 to -0.00). Magnesium sulphate may increase hospital re-admission rate within 30 days of discharge (risk ratio (RR) 3.16, 95% CI 1.20 to 8.27; 158 children; low-certainty evidence). None of our primary outcomes were measured for magnesium sulphate compared with hypertonic saline (1 RCT, 220 children). Effects were uncertain on the duration of hospital stay in days (MD 0.00, 95% CI -0.28 to 0.28), and on clinical severity on the Respiratory Distress Assessment Instrument (RDAI) score at 25 to 48 hours (MD 0.10, 95% CI -0.39 to 0.59). There were no events of mortality or adverse effects for magnesium sulphate, with or without salbutamol, compared with salbutamol (1 RCT, 57 children). Effects on the duration of hospital stay were uncertain (magnesium sulphate: 24 hours (95% CI 25.8 to 47.4), magnesium sulphate + salbutamol: 20 hours (95% CI 15.3 to 39.0), and salbutamol: 24 hours (95% CI 23.4 to 76.9)). None of our primary outcomes were measured for magnesium sulphate + epinephrine compared with no treatment or normal saline + epinephrine (1 RCT,120 children). Effects were uncertain for the duration of hospital stay in hours (MD -0.40, 95% CI -3.94 to 3.14), and for RDAI scores (0 to 24 hours: MD -0.20, 95% CI -1.06 to 0.66; and 25 to 48 hours: MD -0.90, 95% CI -1.75 to -0.05). AUTHORS' CONCLUSIONS: There is insufficient evidence to establish the efficacy and safety of magnesium sulphate for treating children up to two years of age with acute bronchiolitis. No evidence was available for time to recovery, duration of mechanical ventilation and intensive care unit stay, or pulmonary function. There was no information about adverse events for some comparisons. Well-designed RCTs to assess the effects of magnesium sulphate for children with acute bronchiolitis are needed. Important outcomes, such as time to recovery and adverse events should be measured.

INTRODUCTION: Statistical data on the structure of acute respiratory diseases incidence in the paediatric population are still scarce. The demand for such data results mainly from the need to constantly implement new systemic and economic solutions. The aim of the study was to attempt to use reported data for an assessment of the incidence of acute respiratory diseases in various age groups. MATERIAL AND METHODS: An analysis of selected acute respiratory diseases was conducted in relation to diagnoses reported from 1 January to 31 December 2014 to the National Health Fund (NFZ, Narodowy Fundusz Zdrowia) in accordance with the codes of the International Statistical Classification of Diseases and Related Health Problems, 10th Revision. The study was conducted under the Knowledge Education Development operational programme co-funded by the European Social Fund. RESULTS: A total of 101,000 children were hospitalised due to acute respiratory diseases, which amounted to 1,554 hospitalisa-tions per 100.000. The most common causes of hospitalisation were pneumonia and bronchitis/bronchiolitis. Boys were hospital-ised more often in each age group. The shortest average length of stay (ALOS) was 5.21 days and concerned hospitalisation due to bronchitis. The longest length of stay for children was due to tuberculosis (14.3 days). The highest age average of a child was recorded in pleural diseases (10.51 years) and the lowest in bronchitis (2.93 years). Rehospitalisation was necessary in children in whom tuberculosis or pleural diseases were diagnosed (1.43 vs 1.34). A total of 67 inpatient deaths were recorded, of which 19 were due to pneumonia or its complications. CONCLUSIONS: Epidemiological data reported to the National Health Fund (NFZ) seem quite reliable and do not differ significantly from those reported in other European countries. The analysed data may be useful in estimating health needs in paediatrics.

Respiratory syncytial virus (RSV) infection is associated with oxidative lung injury, decreased levels of antioxidant enzymes (AOEs), and the degradation of the transcription factor NF-E2-related factor 2 (NRF2), a master regulator of AOE expression. Single nucleotide polymorphisms (SNPs) in AOE and NRF2 genes have been associated with various lung disorders. To test whether specific NRF2 and/or AOE gene SNPs in children with RSV lower respiratory tract infection were associated with disease severity, one hundred and forty one children <24 month of age with bronchiolitis were assessed for seven AOE and two NRF2 SNPs, and data were correlated with disease severity, which was determined by need of oxygen supplementation and intensive care support. One SNP in the promoter region of the catalase gene, rs1001179, which is associated with higher enzyme expression, was significantly underrepresented (p = 0.01, OR 0.38) among patients with moderate to severe RSV bronchiolitis, suggesting a protective effect against disease severity. Our results suggest that increasing catalase expression/activity could exert a protective role in the context of RSV infection and represent a potential novel therapeutic target to ameliorate viral-induced lung disease.

OBJECTIVES: In 2014, the American Academy of Pediatrics published bronchiolitis guidelines recommending against the use of bronchodilators. For the winter of 2015 to 2016, we aimed to reduce the proportion of emergency department patients with bronchiolitis receiving albuterol from 43% (previous winter rate) to <35% and from 18% (previous winter rate) to <10% in the inpatient setting. METHODS: A team identified key drivers of albuterol use and potential interventions. We implemented changes to our pathway and the associated order set recommending against routine albuterol use and designed education to accompany the pathway changes. We monitored albuterol use through weekly automated data extraction and reported results back to clinicians. We measured admission rate, length of stay, and revisit rate as balancing measures for the intervention. RESULTS: The study period included 3834 emergency department visits and 1119 inpatient hospitalizations. In the emergency department, albuterol use in children with bronchiolitis declined from 43% to 20% and was <3 SD control limits established in the previous year, meeting statistical thresholds for special cause variation. Inpatient albuterol use decreased from 18% to 11% of patients, also achieving special cause variation and approaching our goal. The changes in both departments were sustained through the entire bronchiolitis season, and admission rate, length of stay, and revisit rates remained unchanged. CONCLUSIONS: Using a multidisciplinary group that redesigned a clinical pathway and order sets for bronchiolitis, we substantially reduced albuterol use at a large children's hospital without impacting other outcome measures.

OBJECTIVE: This study aimed (1) to reduce use of ineffective testing and therapies in children with bronchiolitis across outpatient settings in a large pediatric health care system and (2) to assess the cost impact and sustainability of these initiatives. METHODS: We designed a system-wide quality improvement project for patients with bronchiolitis seen in 3 emergency departments (EDs) and 5 urgent care (UC) centers. Interventions included development of a best-practice guideline and education of all clinicians (physicians, nurses, and respiratory therapists), ongoing performance feedback for physicians, and a small physician financial incentive. Measures evaluated included use of chest x-ray (CXR), albuterol, viral testing, and direct (variable) costs. Data were tracked using statistical process control charts. RESULTS: For 3 bronchiolitis seasons, albuterol use decreased from 54% to 16% in UC and from 45% to 16% in ED. Chest x-ray usage decreased from 29% to 9% in UC and from 21% to 12% in the ED. Viral testing in UC decreased from 18% to 2%. Cost of care was reduced by $283,384 within our system in the first 2 seasons following guideline implementation. Improvements beginning in the first bronchiolitis season were sustained and strengthened in the second and third seasons. Admissions from the ED and admissions after return to the ED within 48 hours of initial discharge did not change. CONCLUSION: A system-wide quality improvement project involving multiple outpatient care settings reduced the use of ineffective therapies and interventions in patients with bronchiolitis and resulted in significant cost savings. Improvements in care were sustained for 3 bronchiolitis seasons.

Objectives Viral bronchiolitis is the most common cause of infant hospitalization. Folic acid supplementation is important during the periconceptional period to prevent neural tube defects. An area of investigation is whether higher prenatal folate is a risk factor for childhood respiratory illnesses. We investigated the association between maternal 2nd trimester plasma folate levels and infant bronchiolitis. Methods We conducted a retrospective cohort analysis in a subset of mother-infant dyads (n = 676) enrolled in the Conditions Affecting Neurocognitive Development and Learning in Early Childhood study and Tennessee Medicaid. Maternal folate status was determined using 2nd trimester (16-28 weeks) plasma samples. Bronchiolitis diagnosis in the first year of life was ascertained using International Classification of Diagnosis-9 codes from Medicaid administrative data. We used multivariable logistic regression to assess the adjusted association of prenatal folate levels and infant bronchiolitis outcome. Results Half of the women in this lower-income and predominately African-American (84%) study population had high levels of folate (median 2nd trimester level 19.2 ng/mL) and 21% of infants had at least one bronchiolitis healthcare visit. A relationship initially positive then reversing between maternal plasma folate and infant bronchiolitis was observed that did not reach statistical significance (poverall = .112, pnonlinear effect = .088). Additional adjustment for dietary methyl donor intake did not significantly alter the association. Conclusions for Practice Results did not confirm a statistically significant association between maternal 2nd trimester plasma folate levels and infant bronchiolitis. Further work is needed to investigate the role of folate, particularly higher levels, in association with early childhood respiratory illnesses.

BACKGROUND AND OBJECTIVES: We sought to implement systematic tobacco dependence interventions for parents and/or caregivers as secondary aims within 2 multisite quality improvement (QI) collaboratives for bronchiolitis. We hypothesized that iterative improvements in tobacco dependence intervention strategies would result in improvement in outcomes between collaboratives. METHODS: This study involved 2 separate yearlong, multisite QI collaboratives that were focused on care provided to inpatients with a primary diagnosis of bronchiolitis. In each collaborative, we provided tools and training in tobacco dependence treatment and expert coaching on interventions for parents as a secondary aim. Data were collected by chart review and results analyzed by using analysis of means and statistical process control analysis. Outcomes between collaboratives were compared by using relative risks. RESULTS: Between both collaboratives, 56 hospitals participated and 6258 inpatient charts were reviewed. In the first collaborative, 22% of identified parents who smoke received tobacco dependence interventions at baseline. This rate increased to 51% during the postintervention period, with special cause revealed by analysis of means. In the second collaborative, 31% of parents who smoke received baseline interventions. This rate increased to 53% by the conclusion of the collaborative, with special cause revealed by statistical process control analysis. The relative risk for providing any cessation intervention in 1 collaborative versus the other was 0.9 (confidence interval 0.8-1.1). CONCLUSIONS: Tobacco dependence treatment of parents and/or caregivers can be integrated into bronchiolitis QI by using relatively low-resource strategies. Using a more intensive QI intervention did not alter the rates of screening or intervention for caregivers who smoke.

Bronchiolitis is the leading cause of morbidity and hospitalization in infants under the age of one year. Supportive treatments and regular assessment remain the mainstay of care for infants admitted to hospital. Nurses play an important role in the assessment of infants with bronchiolitis; however, this is not well described in the literature and consequently little is known about what strategies nurses employ in assessing infants with bronchiolitis. The aim of this study was to explore bronchiolitis assessment in the context of nursing practice. A naturalistic inquiry study was undertaken using think aloud and retrospective probing data collection methods. The results revealed that the information gathered by nurses in their assessment of infants with bronchiolitis was varied and the process of acquiring and evaluating this information was multifaceted and holistic in nature. A close partnership between the nurse and mother was identified, and the mother's expert knowledge and ability to identify subtle changes in the infant's clinical condition over time was essential to the assessment process. The assessment partnership with families provides nurses with the most comprehensive and holistic view of the infant's clinical condition and vital assessment information could be lost if this partnership does not occur.
