Initiatives to reduce treatments in bronchiolitis in the emergency department and primary care

Factors associated with salbutamol overuse in bronchiolitis

Numerous studies have shown that quality improvement methods can reduce the use of medications in the management of bronchiolitis. Our objective is to identify factors related to the overuse of salbutamol in the treatment of bronchiolitis before and after an improvement initiative. Observational study of sociodemographic and clinical factors associated with the use of salbutamol in children diagnosed with bronchiolitis. This was a secondary analysis of a prospective cohort study conducted at 135 primary care (PC) centers and eight pediatric emergency departments (ED) in the Osakidetza/Basque Health Service (Spain) in two epidemic seasons between which a bronchiolitis integrated care pathway (BICP) had been implemented: pre-intervention season from October 2018 to March 2019 and post-intervention season from October 2019 to March 2020. Generalized linear mixed models were used to estimate association of studied variables on use of salbutamol over the two seasons. Four thousand one hundred thirty-four ED attendances and 8573 PC visits were included, of which 1936 (46.8%). And 4067 (47.4%) occurred in the post-intervention period respectively. Six independent risk factors were associated with overuse of salbutamol in both seasons: age ≥ 1 year, aOR 2.32 (2.01 to 2.68) in PC centers, and aOR 6.84 (4.98 to 9.39) in EDs; being seen in the last third of the bronchiolitis season, aOR 1.82 (1.51 to 2.18) in PC centers and aOR 1.78 (1.19 to 2.64) in EDs; making more than one visit to the PC center, aOR 4.18 (3.32 to 5.27) or the ED, aOR 2.06 (1.59 to 2.66); being seen by a general practitioner, aOR 1.97 (1.58 to 2.46) in PC centers; and having a more severe episode, aOR 3.01 (1.89 to 4.79) in EDs.     Conclusion:There are factors associated with salbutamol overuse in children diagnosed with bronchiolitis in PC and emergency settings that persist after the deployment of quality improvement initiatives. What is Known: • Quality improvement initiatives have been shown to decrease the use of non-evidence-based treatments and testing in bronchiolitis. • The magnitude and pattern of change in the use of medications linked to the quality improvement initiatives are not uniform across the same health service. What is New: • Children diagnosed with bronchiolitis ≥ 1 year of age, seen in the last third of the bronchiolitis season, attending more than once, treated by a general practitioner, and/or with more severe episodes are more likely to be treated with salbutamol. • These factors may remain present despite the implementation of improvement initiatives focused on reducing the use of medications in the management of bronchiolitis.

Different Pediatric Acute Care Settings Influence Bronchiolitis Management: A 10-Year Retrospective Study

Bronchiolitis is the main cause of hospitalization in infants. Diagnosis is clinical, and treatment is based on hydration and oxygen therapy. Nevertheless, unnecessary diagnostic tests and pharmacological treatments are still very common. This retrospective study aimed to evaluate whether the setting of bronchiolitis care influences diagnostic and therapeutic choices. The management of 3201 infants, referred to our Italian Tertiary Care Center for bronchiolitis between 2010 and 2020, was analyzed by comparing children discharged from the pediatric emergency department (PEDd group) undergoing short-stay observation (SSO group) and hospitalization. Antibiotic use in PEDd, SSO, and ward was 59.3% vs. 51.6% vs. 49.7%, respectively (p < 0.001); inhaled salbutamol was mainly administered in PEDd and during SSO (76.1% and 82.2% vs. 38.3% in ward; p < 0.001); the use of corticosteroids was higher during SSO and hospitalization (59.6% and 49.1% vs. 39.0% in PEDd; p < 0.001); inhaled adrenaline was administered mostly in hospitalized infants (53.5% vs. 2.5% in SSO and 0.2% in PEDd; p < 0.001); chest X-ray use in PEDd, SSO, and ward was 30.3% vs. 49.0% vs. 70.5%, respectively (p < 0.001). In a multivariate analysis, undergoing SSO was found to be an independent risk factor for the use of systemic corticosteroid and salbutamol; being discharged at home was found to be a risk factor for antibiotic prescription; undergoing SSO and hospitalization resulted as independent risk factors for the use of CXR. Our study highlights that different pediatric acute care settings could influence the management of bronchiolitis. Factors influencing practice may include a high turnover of PED medical staff, personal reassurance, and parental pressure.

UPDATE - 2022 Italian guidelines on the management of bronchiolitis in infants

Bronchiolitis is an acute respiratory illness that is the leading cause of hospitalization in young children. This document aims to update the consensus document published in 2014 to provide guidance on the current best practices for managing bronchiolitis in infants. The document addresses care in both hospitals and primary care. The diagnosis of bronchiolitis is based on the clinical history and physical examination. The mainstays of management are largely supportive, consisting of fluid management and respiratory support. Evidence suggests no benefit with the use of salbutamol, glucocorticosteroids and antibiotics with potential risk of harm. Because of the lack of effective treatment, the reduction of morbidity must rely on preventive measures. De-implementation of non-evidence-based interventions is a major goal, and educational interventions for clinicians should be carried out to promote high-value care of infants with bronchiolitis. Well-prepared implementation strategies to standardize care and improve the quality of care are needed to promote adherence to guidelines and discourage non-evidence-based attitudes. In parallel, parents' education will help reduce patient pressure and contribute to inappropriate prescriptions. Infants with pre-existing risk factors (i.e., prematurity, bronchopulmonary dysplasia, congenital heart diseases, immunodeficiency, neuromuscular diseases, cystic fibrosis, Down syndrome) present a significant risk of severe bronchiolitis and should be carefully assessed. This revised document, based on international and national scientific evidence, reinforces the current recommendations and integrates the recent advances for optimal care and prevention of acute bronchiolitis.

Reducing Unnecessary Treatment of Bronchiolitis Across a Large Regional Health Service in Spain

OBJECTIVES

A bronchiolitis integrated care pathway (BICP) proved useful in reducing the use of unnecessary medications at a local level. The aim of this study was to reduce overtreatment by scaling up the BICP across our regional health service in the 2019 and 2020 bronchiolitis season.

METHODS

We conducted a quality improvement (QI) initiative in 115 primary care (PC) centers and 7 hospitals in the Basque Country, Spain, from October 2019 to March 2020. The primary outcome measure was the percentage of children prescribed salbutamol comparing the rate to that in the previous bronchiolitis season (October 2018-March 2019). Secondary outcomes were the use of other medications. Balancing measures were hospitalization and unscheduled return rates.

RESULTS

We included 8153 PC visits, 3424 emergency department (ED) attendances, and 663 inpatient care episodes, of which 3817 (46.8%), 1614 (47.1%), and 328 (49.4%) occurred in the postintervention period, respectively. Salbutamol use decreased from 27.1% to 4.7%, 29.5% to 3.0%, and 44.4% to 3.9% (P &lt; .001) in PC centers, Eds, and hospital wards, respectively. In PC, corticosteroid and antibiotic prescribing rates fell from 10.1% to 1.7% and 13.7% to 5.1%, respectively (P &lt; .001). In EDs and hospital wards, epinephrine use rates fell from 14.2% to 4.2% (P &lt; .001) and 30.4% to 19.8% (P = .001), respectively. No variations were noted in balancing measures.

CONCLUSIONS

The scaling up of the BICP was associated with significant decreases in the use of medications in managing bronchiolitis across a regional health service without unintended consequences.

Patient, Provider, and Health Care System Characteristics Associated With Overuse in Bronchiolitis

BACKGROUND AND OBJECTIVES

The American Academy of Pediatrics recommends against the routine use of β-agonists, corticosteroids, antibiotics, chest radiographs, and viral testing in bronchiolitis, but use of these modalities continues. Our objective for this study was to determine the patient, provider, and health care system characteristics that are associated with receipt of low-value services.

METHODS

Using the Virginia All-Payers Claims Database, we conducted a retrospective cross-sectional study of children aged 0 to 23 months with bronchiolitis (code J21, International Classification of Diseases, 10th Revision) in 2018. We recorded medications within 3 days and chest radiography or viral testing within 1 day of diagnosis. Using Poisson regression, we identified characteristics associated with each type of overuse.

RESULTS

Fifty-six percent of children with bronchiolitis received ≥1 form of overuse, including 9% corticosteroids, 17% antibiotics, 20% β-agonists, 26% respiratory syncytial virus testing, and 18% chest radiographs. Commercially insured children were more likely than publicly insured children to receive a low-value service (adjusted prevalence ratio [aPR] 1.21; 95% confidence interval [CI]: 1.15-1.30; P < .0001). Children in emergency settings were more likely to receive a low-value service (aPR 1.24; 95% CI: 1.15-1.33; P < .0001) compared with children in inpatient settings. Children seen in rural locations were more likely than children seen in cities to receive a low-value service (aPR 1.19; 95% CI: 1.11-1.29; P < .0001).

CONCLUSIONS

Overuse in bronchiolitis remains common and occurs frequently in emergency and outpatient settings and rural locations. Quality improvement initiatives aimed at reducing overuse should include these clinical environments.

The Evolution of Quality Benchmarks for Bronchiolitis

BACKGROUND AND OBJECTIVES

Evidence suggests that average performance on quality measures for bronchiolitis has been improving over time, but it is unknown whether optimal performance, as defined by Achievable Benchmarks of Care (ABCs), has also changed. Thus, we aimed to compare ABCs for established bronchiolitis quality measures between 2 consecutive time periods. As a secondary aim, we evaluated performance gaps, defined as the difference between median performance and ABCs, to identify measures that may benefit most from targeted quality initiatives.

METHODS

We used hospital administrative data from the Pediatric Health Information System database to calculate ABCs and performance gaps for nonrecommended bronchiolitis tests and treatments in 2 groups (patients discharged from the emergency department [ED] and those hospitalized) over 2 time periods (2006-2014 and 2014-2019) corresponding to publication of national bronchiolitis guidelines.

RESULTS

Substantial improvements were identified in ABCs for chest radiography (ED -8.8% [confidence interval (CI) -8.3% to -9.4%]; hospitalized -17.5% [CI -16.3% to -18.7%]), viral testing (hospitalized -14.6% [CI -13.5% to -15.7%]), antibiotic use (hospitalized -10.4% [CI -8.9% to -11.1%]), and bronchodilator use (ED -9.0% [CI -8.4% to -9.6%]). Viral testing (ED 11.5% [CI 10.9% to 12.1%]; hospitalized 21.5% [CI 19.6% to 23.4%]) and bronchodilator use (ED 13.8% [CI 12.8% to 14.8%]; hospitalized 22.8% [CI 20.6% to 25.1%]) demonstrated the largest performance gaps.

CONCLUSIONS

Marked changes in ABCs over time for some bronchiolitis quality measures highlight the need to reevaluate improvement targets as practice patterns evolve. Measures with large performance gaps, such as bronchodilator use and viral testing, are recommended as targets for ongoing quality improvement initiatives.

[Decrease in the use of bronchodilators in the management of bronchiolitis after applying improvement initiatives]

INTRODUCTION

In the treatment of patients with acute bronchiolitis there is great variability in clinical practice. Treatments whose efficacy has not been demonstrated are frequently used despite the recommendations contained in the Clinical Practice Guidelines.

MATERIAL AND METHODS

A quality improvement strategy is implemented in the care of patients with acute bronchiolitis in the Emergency Department, which is maintained for five years and is periodically updated to be increasingly restrictive regarding the use of bronchodilators. To evaluate the impact of the intervention, a retrospective study of the rates of prescription of bronchodilators in children diagnosed with acute bronchiolitis in the month of December of four epidemic periods (2012, 2014, 2016 and 2018) was carried out.

RESULTS

1767 children are included. There were no differences regarding age, respiratory rate, oxygen saturation or the estimated severity in each of the study seasons. The use of salbutamol in the Emergency Department decreased from 51.2% (95% CI: 46.6%-55.8%) in 2012 to 7.8% (95% CI: 5.7%-10.5%) in 2018 (P<.001) and epinephrine prescription rates fell from 12.9% (95% CI: 10.1%-16.3%) to 0.2% (95% CI: 0-1.1%) (P<.001). At the same time, there was a decrease in the median time of attendance in the Emergency Department and in the admission rate without changing the readmission rate in 72h.

CONCLUSIONS

The systematic and continuous deployment over time of actions aimed at reducing the use of salbutamol and epinephrine in the treatment of bronchiolitis, prior to the epidemic period, seems an effective strategy to reduce the use of bronchodilators in the Emergency Department.

Reducing Unnecessary Treatments for Acute Bronchiolitis Through an Integrated Care Pathway

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.

Impact of bronchiolitis guidelines publication on primary care prescriptions in the Italian pediatric population

In Italy, two clinical practice guidelines for the diagnosis and treatment of bronchiolitis were published in October 2014 and December 2015. We evaluated prescriptions for bronchiolitis in children aged 0–24 months before (December 2012–December 2014), in between (December 2014–December 2015) and after (December 2015–December 2018) the guidelines publications. Data were retrieved from the Pedianet database; the measured outcomes were prescriptions rates of antibiotics, corticosteroids, β2-agonists, and other respiratory drugs. In 1011 out of 1581 episodes, patients received at least one treatment, with a total of 2003 prescriptions. The rate of treated bronchiolitis decreased from 66% to 57% (p < 0.001) after the publication of the second guideline; the highest reduction was in younger patients (from 57% to 44%, p = 0.013). Overall antibiotic prescriptions rate did not change, with 31.6% of the patients still receiving them. Our results confirm unnecessary non-evidence-based treatments in the primary care setting, with few changes after the guidelines publications.

Treatment for acute bronchiolitis before and after implementation of new national guidelines: a retrospective observational study from primary and secondary care in Oslo, Norway

BACKGROUND

Acute bronchiolitis treatment guidelines changed in Norway in 2013, no longer recommending the use of nebulised epinephrine. We aimed to assess whether these changes were successfully implemented in both primary and secondary care. Secondary aims were to compare the difference in management of acute bronchiolitis patients in primary and secondary care between 2009 and 2017.

METHODS

We retrospectively registered data on demographics, clinical features and management from electronic medical records of all infants (<12 months of age) diagnosed with acute bronchiolitis at a primary care centre (Oslo Accident and Emergency Outpatient Clinic) and a secondary care centre (Oslo University Hospital) in Norway in 2009, 2014 and 2017. All patient records were individually reviewed to ensure data accuracy.

RESULTS

We included 680 (36.3%) patients from primary care and 1195 (63.7%) from secondary care. There was a reduction in the use of nebulised epinephrine from 2009 to 2017 from 66.9% to 16.1% of cases (p<0.001) in primary care and from 59.1% to 4.9% (p<0.001) in secondary care. In parallel, there was an increase in the use of nebulised saline treatment, from 0.8% to 53.8% (p<0.001) in primary care and from 39.3% to 65.3% (p<0.001) in secondary care. The decrease in the use of nebulised racemic epinephrine occurred earlier in secondary care than in primary care; 13.4% vs 56.1%, respectively, in 2014.

CONCLUSIONS

Implementation of the new guidelines on the treatment of acute bronchiolitis was successfully implemented in both primary and secondary care.
