Perspectives of Health Care Personnel on the Benefits of Bronchiolitis Interventions.

Many interventions in bronchiolitis are low-value or poorly studied. Inpatient bronchiolitis management is multidisciplinary, with varying degrees of registered nurse (RN) and respiratory therapist (RT) autonomy. Understanding the perceived benefit of interventions for frontline health care personnel may facilitate deimplementation efforts. Our objective was to examine perceptions surrounding the benefit of common inpatient bronchiolitis interventions. We conducted a cross-sectional survey of inpatient pediatric RNs, RTs, and physicians/licensed practitioners (P/LPs) (eg, advanced-practice practitioners) from May to December of 2021 at 9 university-affiliated and 2 community hospitals. A clinical vignette preceded a series of inpatient bronchiolitis management questions. A total of 331 surveys were analyzed with a completion rate of 71.9%: 76.5% for RNs, 57.4% for RTs, and 71.2% for P/LPs. Approximately 54% of RNs and 45% of RTs compared with 2% of P/LPs believe albuterol would be "extremely or somewhat likely" to improve work of breathing (P < .001). Similarly, 52% of RNs, 32% of RTs, and 23% of P/LPs thought initiating or escalating oxygen in the absence of hypoxemia was likely to improve work of breathing (P < .001). Similar differences in perceived benefit were observed for steroids, nebulized hypertonic saline, and deep suctioning, but not superficial nasal suctioning. Hospital type (community versus university-affiliated) did not impact the magnitude of these differences. Variation exists in the perceived benefit of several low-value or poorly studied bronchiolitis interventions among health care personnel, with RNs/RTs generally perceiving higher benefit. Deimplementation, educational, and quality improvement efforts should be designed with an interprofessional framework.

Antibiotic Use for Inpatient Bronchiolitis: Did National Guidelines Impact Practice at a Pediatric Hospital?

Bronchiolitis is a common lower respiratory tract infection that affects infants and young children. Because of variability in physician practice, inpatient management varies among pediatricians. In 2014, the Canadian Pediatric Society published national guidelines aimed at standardizing the inpatient management of this illness, which included recommending against the need for antibiotics for most patients. The study objective was to evaluate antibiotic prescription and supportive investigations for inpatient management of bronchiolitis before and after the publication of national guidelines. This study was a single-center retrospective chart review of inpatients with bronchiolitis. We included healthy children 1 to 24 months of age who were admitted from November 2011 to October 2016. Those admitted before December 2014 were analyzed in the preguidelines cohort; the remaining, in the postguidelines cohort. The main outcome was antibiotic prescription. The secondary outcome was the frequency of chest radiographs, nasopharyngeal swabs, and blood cultures. A total of 131 patients were included in the first cohort; 71, in the second cohort. The rates of antibiotic initiation were almost equal in both cohorts (∼44%; P = .98). More antibiotics were discontinued during hospitalization in the second cohort compared with the first cohort (10% vs 20%; P = .001). Significantly fewer patients were discharged with antibiotics in the second cohort (31% vs 16%; P = .02). Our study revealed a reduction in antibiotic use after the release of national guidelines, illustrating that antibiotic prescribing practices can change. However, there is still a pressing need for local initiatives to continue to reduce the unnecessary use of antibiotics within the pediatric setting.

Practice variation in the management of children hospitalized with bronchiolitis: A Canadian perspective.

To describe variations in the monitoring, treatment, and discharge of children hospitalized with bronchiolitis among physicians across Canadian paediatric teaching hospitals. We conducted an electronic survey of paediatricians with experience in the management of inpatient bronchiolitis at 20 Canadian paediatric teaching hospitals. Only physicians who worked a minimum of 6 weeks on their hospital inpatient unit in the 2015 calendar year were eligible to participate in the study. The questionnaire explored the monitoring, treatment, and discharge of children with bronchiolitis. Central tendency (mean) and dispersion (SD) statistics were produced for continuous variables and frequency distributions for categorical variables. A total of 142 respondents were included in the analysis. 45.1% reported the routine use of continuous oxygen saturation monitoring. 27.5% used a higher cut-off for oxygen supplementation of 92% and 12.7% use a lower cut-off of 88%. 29.6% routinely used deep nasal suctioning. Seventy-three per cent reported using nebulized therapies. 55.6% reported having preprinted order sheets or guidelines for management of inpatient bronchiolitis at their institutions and 28.2% reported having specific discharge criteria. The length of time required to be off oxygen prior to discharge varied (31% at 12 hours, 27.5% at 24 hours, and 24.6% after the last sleep period without oxygen). There is significant practice variation in the monitoring, treatment, and discharge of children hospitalized with bronchiolitis within and between Canadian paediatric teaching hospitals. Future research is needed to establish best practices, effective knowledge translation, and implementation strategies to standardize care and decrease length of stay.

Reducing Length of Stay and Resource Utilization in the Care of Bronchiolitis Patients at a Community Hospital

AIMS To reduce the length of stay (LOS) of patients admitted with bronchiolitis to a community pediatric inpatient program by 12 hours by March 2017. Additional aim was to decrease the use of medications (albuterol, steroids, antibiotics) and diagnostic tests (Chest radiographs and Viral testing) by 30 percent by the same time. METHODS The QI effort was undertaken by a multidisciplinary team of physicians and nurses at our two inpatient sites using the IHI model for improvement. In the first PDSA cycle (January-April 2016), we used the inpatient bronchiolitis pathway at our affiliated tertiary care hospital …

Sustainability in the AAP Bronchiolitis Quality Improvement Project

Background and objectives Adherence to American Academy of Pediatrics (AAP) bronchiolitis clinical practice guideline recommendations improved significantly through the AAP's multiinstitutional collaborative, the Bronchiolitis Quality Improvement Project (BQIP). We assessed sustainability of improvements at participating institutions for 1 year following completion of the collaborative. Methods Twenty-one multidisciplinary hospital-based teams provided monthly data for key inpatient bronchiolitis measures during baseline and intervention bronchiolitis seasons. Nine sites provided data in the season following completion of the collaborative. Encounters included children younger than 24 months who were hospitalized for bronchiolitis without comorbid chronic illness, prematurity, or intensive care. Changes between baseline-, intervention-, and sustainability-season data were assessed using generalized linear mixed-effects models with site-specific random effects. Differences between hospital characteristics, baseline performance, and initial improvement between sites that did and did not participate in the sustainability season were compared. Results A total of 2275 discharges were reviewed, comprising 995 baseline, 877 intervention, and 403 sustainability- season encounters. Improvements in all key bronchiolitis quality measures achieved during the intervention season were maintained during the sustainability season, and orders for intermittent pulse oximetry increased from 40.6% (95% confidence interval [CI], 22.8-61.1) to 79.2% (95% CI, 58.0- 91.3). Sites that did and did not participate in the sustainability season had similar characteristics. Discussion BQIP participating sites maintained improvements in key bronchiolitis quality measures for 1 year following the project's completion. This approach, which provided an evidence-based best-practice toolkit while building the quality-improvement capacity of local interdisciplinary teams, may support performance gains that persist beyond the active phase of the collaborative.

A Multicenter Collaborative to Reduce Unnecessary Care in Inpatient Bronchiolitis

Evidence-based Guidelines for acute viral bronchiolitis recommend primarily supportive care, but unnecessary care remains well documented. Published quality improvement work has been accomplished in children's hospitals, but little broad dissemination has been reported outside of those settings. We sought to use a voluntary collaborative strategy to disseminate best practices to reduce overuse of unnecessary care in children hospitalized for bronchiolitis in community settings. This project was a quality improvement collaborative consisting of monthly interactive webinars with online data collection and feedback. Data were collected by chart review for 2 bronchiolitis seasons, defined as January, February, and March of 2013 and 2014. Patients aged <24 months hospitalized for bronchiolitis and without chronic illness, prematurity, or intensive care use were included. Results were analyzed using run charting, analysis of means, and nonparametric statistics. There were 21 participating hospitals contributing a total of 1869 chart reviews to the project, 995 preintervention and 874 postintervention. Mean use of any bronchodilator declined by 29% (P = .03) and doses per patient decreased 45% (P < .01). Mean use of any steroids declined by 68% (P < .01), and doses per patient decreased 35% (P = .04). Chest radiography use declined by 44% (P = .05). Length of stay decreased 5 hours (P < .01), and readmissions remained unchanged. A voluntary collaborative was effective in reducing unnecessary care among a cohort of primarily community hospitals. Such a strategy may be generalizable to the settings where the majority of children are hospitalized in the United States.

3% Hypertonic Saline Versus Normal Saline in Inpatient Bronchiolitis: A Randomized Controlled Trial.

Bronchiolitis, the most common reason for hospitalization in children younger than 1 year in the United States, has no proven therapies effective beyond supportive care. We aimed to investigate the effect of nebulized 3% hypertonic saline (HS) compared with nebulized normal saline (NS) on length of stay (LOS) in infants hospitalized with bronchiolitis. We conducted a prospective, randomized, double-blind, controlled trial in an urban tertiary care children's hospital in 227 infants younger than 12 months old admitted with a diagnosis of bronchiolitis (190 completed the study); 113 infants were randomized to HS (93 completed the study), and 114 to NS (97 completed the study). Subjects received 4 mL nebulized 3% HS or 4 mL 0.9% NS every 4 hours from enrollment until hospital discharge. The primary outcome was median LOS. Secondary outcomes were total adverse events, subdivided as clinical worsening and readmissions. Patient characteristics were similar in groups. In intention-to-treat analysis, median LOS (interquartile range) of HS and NS groups was 2.1 (1.2-4.6) vs 2.1 days (1.2-3.8), respectively, P = .73. We confirmed findings with per-protocol analysis, HS and NS groups with 2.0 (1.3-3.3) and 2.0 days (1.2-3.0), respectively, P = .96. Seven-day readmission rate for HS and NS groups were 4.3% and 3.1%, respectively, P = .77. Clinical worsening events were similar between groups (9% vs 8%, P = .97). Among infants admitted to the hospital with bronchiolitis, treatment with nebulized 3% HS compared with NS had no difference in LOS or 7-day readmission rates.

Effectiveness of quality improvement in hospitalization for bronchiolitis: a systematic review.

Bronchiolitis causes nearly 20% of all acute care hospitalizations for young children in the United States. Unnecessary testing and medication for infants with bronchiolitis contribute to cost without improving outcomes. The goal of this study was to systematically review the quality improvement (QI) literature on inpatient bronchiolitis and to propose benchmarks for reducing unnecessary care. Assisted by a medical librarian, we searched Medline, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library. Studies describing any active QI intervention versus usual care in hospitalized children <2 years of age were included. Data were extracted and confirmed by multiple investigators and pooled by using a random effects model. Benchmarks were calculated by using achievable benchmarks of care methods. Fourteen studies involving >12000 infants were reviewed. QI interventions resulted in 16 fewer patients exposed to repeated doses of bronchodilators per 100 hospitalized (7 studies) (risk difference: 0.16 [95% confidence interval: 0.11-0.21]) and resulted in 5.3 fewer doses of bronchodilator given per patient (95% confidence interval: 2.1-8.4). Interventions resulted in fewer hospitalized children exposed to steroids (5 per 100), chest radiography (9 per 100), and antibiotics (4 per 100). No significant harms were reported. Benchmarks derived from the reported data are: repeated bronchodilator use, 16%; steroid use, 1%; chest radiography use, 42%; and antibiotic use, 17%. The study's heterogeneity limited the ability to classify specific characteristics of effective QI interventions. QI strategies have been demonstrated to achieve lower rates of unnecessary care in children hospitalized with viral bronchiolitis than are the norm.

Impact of Inpatient Bronchiolitis Clinical Practice Guideline Implementation on Testing and Treatment

To determine the association between institutional inpatient clinical practice guidelines (CPGs) for bronchiolitis and the use of diagnostic tests and treatments. A multicenter retrospective cohort study of infants aged 29 days to 24 months with a discharge diagnosis of bronchiolitis was conducted between July 2011 and June 2012. An electronic survey was sent to quality improvement leaders to determine the presence, duration, and method of CPG implementation at participating hospitals. The Wilcoxon rank-sum test was used to perform bivariate comparisons between hospitals with CPGs and those without CPGs. Multivariable analysis was used to determine associations between CPG characteristics and the use of tests and treatments; analyses were clustered by hospital. The response rate to our electronic survey was 77% (33 of 43 hospitals). The majority (85%) had an institutional bronchiolitis CPG in place. Hospitals with a CPG had universal agreement regarding recommendations against routine tests and treatments. The presence of a CPG was not associated with significant reductions in the use of tests and treatments (eg, complete blood count, chest radiography, bronchodilator use, steroid and antibiotic use). A longer interval duration since CPG implementation and presence of an easily accessible online CPG document were associated with significant reductions in the performance of complete blood count and chest radiography and the use of corticosteroids. Other implementation factors demonstrated mixed results. Most children's hospitals have an institutional bronchiolitis CPG in place. The content of these CPGs is largely uniform in practice recommendations against tests and treatments. The presence of institutional CPGs did not significantly reduce the ordering of tests and treatments. Online accessibility of a written CPG and prolonged duration of implementation reduce tests and treatments.

Unnecessary Care for Bronchiolitis Decreases With Increasing Inpatient Prevalence of Bronchiolitis

To measure the association between inpatient bronchiolitis prevalence (IBP) and the delivery of unnecessary tests and treatments to patients hospitalized with bronchiolitis. A multicenter, retrospective, cohort study was performed using the Pediatric Hospital Information System database. All patients 2 months to 2 years of age hospitalized with bronchiolitis during 2004-2008 at participating pediatric hospitals were included. Main outcome measures were the probability of receiving potentially unnecessary care for bronchiolitis, including steroids, intravenously administered antibiotics, chest or neck radiographs, and any laboratory tests during hospitalization. During winter months, with each 1% absolute increase in IBP, patients were less likely to receive steroids (incidence rate ratio: 0.968 [95% confidence interval: 0.960-0.976]; P < .001), radiographs (incidence rate ratio: 0.988 [95% confidence interval: 0.984-0.992]; P < .001), and laboratory tests (incidence rate ratio: 0.992 [95% confidence interval: 0.988-0.995]; P < .001). During summer months, similar associations were observed for steroids and radiographs. No association between IBP and antibiotic use was observed during either time period. The frequency with which several types of unnecessary care were delivered to patients with bronchiolitis seemed to decrease with increasing IBP. This finding suggests that an association exists between contextual information and care delivery during the management of acute illness, and it highlights the importance of such information for delivery of high-quality health care.
