Bronchiolitis management before and after the AAP guidelines

Trends in Low-Value Care Among Children's Hospitals

BACKGROUND AND OBJECTIVES

Longitudinal pediatric low-value care (LVC) trends are not well established. We used the Pediatric Health Information System LVC Calculator, which measures utilization of 30 nonevidenced-based services, to report 7-year LVC trends.

METHODS

This retrospective cohort study applied the LVC Calculator to emergency department (ED) and hospital encounters from January 1, 2016, to December 31, 2022. We used generalized estimating equation models accounting for hospital clustering to assess temporal changes in LVC.

RESULTS

There were 5 265 153 eligible ED encounters and 1 301 613 eligible hospitalizations. In 2022, of 21 LVC measures applicable to the ED cohort, the percentage of encounters with LVC had increased for 11 measures, decreased for 1, and remained unchanged for 9 as compared with 2016. Computed tomography for minor head injury had the largest increase (17%-23%; P < .001); bronchodilators for bronchiolitis decreased (22%-17%; P = .001). Of 26 hospitalization measures, LVC increased for 6 measures, decreased for 9, and was unchanged for 11. Inflammatory marker testing for pneumonia had the largest increase (23%-38%; P = .003); broad-spectrum antibiotic use for pneumonia had the largest decrease (60%-48%; P < .001). LVC remained unchanged or decreased for most medication and procedure measures, but remained unchanged or increased for most laboratory and imaging measures.

CONCLUSIONS

LVC improved for a minority of services between 2016 and 2022. Trends were more favorable for therapeutic (medications and procedures) than diagnostic measures (imaging and laboratory studies). These data may inform prioritization of deimplementation efforts.

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.

Factors associated with nonadherence to the American Academy of Pediatrics 2014 bronchiolitis guidelines: A retrospective study

The latest guideline from the American Academy of Pediatrics for the management of bronchiolitis has helped reduce unnecessary interventions and costs. However, data on patients still receiving interventions are missing. In patients with acute bronchiolitis whose management was assessed and compared with current achievable benchmarks of care, we aimed to identify factors associated with nonadherence to guideline recommendations. In this single-centre retrospective study the management of bronchiolitis pre-guideline (Period 1: 2010 to 2012) was compared with two periods post-guideline (Period 2: 2015 to 2016, early post-guideline; and Period 3: 2017 to 2018, late post-guideline) in otherwise healthy infants aged less than 1 year presenting at the Children's University Hospitals of Geneva (Switzerland). Post-guideline, bronchodilators were more frequently administered to older (>6 months; OR 25.8, 95%CI 12.6-52.6), and atopic (OR 3.5, 95%CI 1.5-7.5) children with wheezing (OR 5.4, 95%CI 3.3-8.7). Oral corticosteroids were prescribed more frequently to older (>6 months; OR 5.2, 95%CI 1.4-18.7) infants with wheezing (OR 4.9, 95% CI 1.3-17.8). Antibiotics and chest X-ray were more frequently prescribed to children admitted to the intensive care unit (antibiotics: OR 4.2, 95%CI 1.3-13.5; chest X-ray: OR 19.4, 95%CI 7.4-50.6). Latest prescription rates were all below the achievable benchmarks of care. In summary, following the latest American Academy of Pediatrics guideline, older, atopic children with wheezing and infants admitted to the intensive care unit were more likely to receive nonevidence-based interventions during an episode of bronchiolitis. These patient profiles are generally excluded from bronchiolitis trials, and therefore not specifically covered by the current guideline. Further research should focus on the benefit of bronchiolitis interventions in these particular populations.

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.

Do the Guidelines Apply?-A Multisite, Combined Stakeholder Qualitative Case Study to Understand Care Decisions in Bronchiolitis

BACKGROUND

Clinical practice guidelines for bronchiolitis recommend against tests and treatments that do not improve outcomes, yet most children admitted with bronchiolitis continue to receive them. An improved understanding of factors that influence care decisions across multiple stakeholders and diverse settings is needed to develop effective strategies to de-implement (or reduce) unnecessary testing and treatment.

METHODS

We explored health care provider, care team, and parent perspectives on testing and treatment in bronchiolitis to develop a combined stakeholder account of care decisions. We conducted a qualitative case study across 2 geographically distinct university affiliated children's hospitals representing a generally low and high test/treatment utilizing hospital respectively from March 2019 to May 2020. We conducted 46 semistructured interviews and 3 focus groups with a total of 74 participants. Data were analyzed using applied thematic analysis and findings were triangulated across participant group and data collection method.

RESULTS

Three themes emerged around care decisions: 1) awareness and perceptions of the guidelines or evidence; 2) perceptions of expected tests or treatments, and 3) organizational culture and existing care processes. Provider and care team participants commonly described parent expectations as drivers of utilization. Conversely, parents generally reported a lack of expectations for tests/treatments and that tests/treatments did not improve their experience of care.

CONCLUSIONS

This study illuminated factors associated with the differential adoption of evidence and targets for future de-implementation strategies. Importantly, incongruent with provider and care team perceptions, parents reported that they desire an evidence-based, less-is-more approach to bronchiolitis care.

Recurrent Wheeze Exacerbations Following Acute Bronchiolitis-A Machine Learning Approach

Introduction: Acute bronchiolitis is one of the most common respiratory infections in infancy. Although most infants with bronchiolitis do not get hospitalized, infants with hospitalized bronchiolitis are more likely to develop wheeze exacerbations during the first years of life. The objective of this prospective cohort study was to develop machine learning models to predict incidence and persistence of wheeze exacerbations following the first hospitalized episode of acute bronchiolitis. Methods: One hundred thirty-one otherwise healthy term infants hospitalized with the first episode of bronchiolitis at a tertiary pediatric hospital in Athens, Greece, and 73 age-matched controls were recruited. All patients/controls were followed up for 3 years with 6-monthly telephone reviews. Through principal component analysis (PCA), a cluster model was used to describe main outcomes. Associations between virus type and the clusters and between virus type and other clinical characteristics and demographic data were identified. Through random forest classification, a prediction model with smallest classification error was identified. Primary outcomes included the incidence and the number of caregiver-reported wheeze exacerbations. Results: PCA identified 2 clusters of the outcome measures (Cluster 1 and Cluster 2) that were significantly associated with the number of recurrent wheeze episodes over 3-years of follow-up (Chi-Squared, p < 0.001). Cluster 1 included infants who presented higher number of wheeze exacerbations over follow-up time. Rhinovirus (RV) detection was more common in Cluster 1 and was more strongly associated with clinical severity on admission (p < 0.01). A prediction model based on virus type and clinical severity could predict Cluster 1 with an overall error 0.1145 (sensitivity 75.56% and specificity 91.86%). Conclusion: A prediction model based on virus type and clinical severity of first hospitalized episode of bronchiolitis could predict sensitively the incidence and persistence of wheeze exacerbations during a 3-year follow-up. Virus type (RV) was the strongest predictor.

Hospital Charges Associated With Critical Bronchiolitis From 2009 to 2019

OBJECTIVES

To evaluate the contribution of PICU care to increasing hospital charges for patients with bronchiolitis over a 10-year study period.

DESIGN

In this retrospective multicenter study, changes in annual hospital charges (adjusted for inflation) were analyzed using linear regression for subjects admitted to the PICU with invasive mechanical ventilation (PICU + IMV) and without IMV (PICU - IMV), and for children not requiring PICU care.

SETTING

Free-standing children's hospitals contributing to the Pediatric Health Information System (PHIS) database.

SUBJECTS

Children less than 2 years with bronchiolitis discharged from a PHIS hospital between July 2009 and June 2019. Subjects were categorized as high risk if they were born prematurely or had a chronic complex condition.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

PICU patients were 26.5% of the 283,006 included subjects but accrued 66% of the total $14.83 billion in charges. Annual charges increased from $1.01 billion in 2009-2010 to $2.07 billion in 2018-2019, and PICU patients accounted for 83% of this increase. PICU + IMV patients were 22% of all PICU patients and accrued 64% of all PICU charges, but PICU - IMV patients without a high-risk condition had the highest relative increase in annual charges, increasing from $76.7 million in 2009-2010 to $377.9 million in 2018-2019 (374% increase, ptrend < 0.001).

CONCLUSIONS

In a multicenter cohort study of children hospitalized with bronchiolitis, PICU patients, especially low-risk children without the need for IMV, were the highest driver of increased hospital charges over a 10-year study period.

SARS-CoV-2 acute bronchiolitis in hospitalized children: Neither frequent nor more severe

INTRODUCTION

Endemic coronaviruses have been found in acute bronchiolitis, mainly as a coinfecting virus. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been responsible for respiratory illness in hospitalized children. The characteristics of patients with bronchiolitis have not been extensively described.

METHODS

Cross-sectional study of patients with bronchiolitis and SARS-CoV-2 infection enrolled in a prospective multicenter cohort of children hospitalized with COVID-19 in Spain from March 1, 2020 to February 28, 2021.

RESULTS

Twelve of 666 children infected with SARS-CoV-2 who required hospital admission met the diagnostic criteria for bronchiolitis (1.8%). Median age was 1.9 months (range: 0.4-10.1). Six cases had household contact with a confirmed or probable COVID-19 case. Main complaints were cough (11 patients), rhinorrhea (10), difficulty breathing (8), and fever (8). Eleven cases were classified as mild or moderate and one as severe. Laboratory tests performed in seven patients did not evidence anemia, lymphopenia, or high C-reactive protein levels. Chest X-rays were performed in six children, and one case showed remarkable findings. Coinfection with metapneumovirus was detected in the patient with the most severe course; Bordetella pertussis was detected in another patient. Seven patients required oxygen therapy. Albuterol was administered in four patients. One patient was admitted to the pediatric intensive care unit. Median length of admission was 4 days (range: 3-14). No patient died or showed any sequelae at discharge. Two patients developed recurrent bronchospasms.

CONCLUSION

SARS-CoV-2 infection does not seem to be a main trigger of severe bronchiolitis, and children with this condition should be managed according to clinical practice guidelines.

Management of Hospitalized Respiratory Syncytial Virus Bronchiolitis in the Pediatric Ward in Spain: Assessing the Impact of a New Clinical Practice Protocol

BACKGROUND

Bronchiolitis caused by the respiratory syncytial virus (RSV) is the main reason for hospitalization in infants. Supportive care is the mainstay of treatment, and tests are restricted to a few indications. During 2015, our hospital bronchiolitis protocol (2015 HBP) was updated according to the latest practice guidelines.

OBJECTIVE

The objective of this study was to assess implementation of the 2015 HBP and the clinical outcome of children aged ≤ 24 months with RSV bronchiolitis admitted to a pediatric ward.

METHODS

We compared the use of treatments and tests, hospital length of stay (LOS), and oxygen requirements before implementation of the 2015 HBP (2014-2015 and 2015-2016 seasons) and after implementation (2016-2017 and 2017-2018 seasons).

RESULTS

The study population comprised 251 children (44.90%) in the first period and 308 (55.10%) in the second (median age 99 days, interquartile range 44-233). After implementation of the 2015 HBP, a statistically significant reduction was found in the percentage of patients undergoing the following treatments or diagnostic tests: salbutamol, from 57.77 to 31.17% (p < 0.001); epinephrine, from 61.75 to 1.30% (p < 0.001); 3% hypertonic saline, from 70.12 to 6.82% (p < 0.001); antibiotics, from 33.07 to 23.05% (p = 0.008); and chest X-ray, from 43.82 to 31.17% (p = 0.001). No statistically significant reductions were observed in the use of corticosteroids and blood tests. Hospital LOS and oxygen requirements were similar in each period.

CONCLUSIONS

Appropriate implementation of the 2015 HBP in the pediatric ward improves the use of medication and chest X-ray without modifying clinical outcomes. However, further efforts are needed to reduce the use of salbutamol, corticosteroids, and blood tests.

Impact of Guidelines Publication on Acute Bronchiolitis Management: 10-Year Experience from a Tertiary Care Center in Italy

Bronchiolitis is the most common lower respiratory tract infection in infants. According to evidence-based guidelines, diagnosis is clinical, there is no need for routine use of laboratory or instrumental tests and therapy is primarily supportive, based on oxygen and adequate fluid supplementation. Nevertheless, unnecessary diagnostic tests and pharmacological treatments are still very common. The aim of this retrospective cohort study was to evaluate how the management of bronchiolitis has changed in the last ten years in a Tertiary Care Center in Italy, assessing adherence to national guidelines. Considering the publication of the Italian inter-society consensus document in 2014, we compared patients admitted in the prior four epidemic seasons with patients admitted in the latter six epidemic seasons. The comparison between the two groups showed a significant reduction in the prescription of systemic corticosteroids (58.9% vs. 41.8%, p < 0.001), nebulized epinephrine (73.8% vs. 38.3%, p < 0.001) and antibiotics (59.5% vs. 42.3%, p < 0.001), together with a drastic decrease in the use of chest X-ray (92.2% vs. 54.4%, p < 0.001). On the contrary, the use of inhaled salbutamol remained substantially stable over time (39.4% vs. 37.6%, p = 0.505). Despite the encouraging results, further efforts are needed to limit the prescription of ineffective therapies like antibiotics and inhaled salbutamol.

Factors Associated With Bronchiolitis Guideline Nonadherence at US Children's Hospitals

BACKGROUND

The objective with this study was to explore factors associated with nonadherence to national bronchiolitis guidelines at 52 children's hospitals.

METHODS

We included patients 1 month to 2 years old with emergency department (ED) or admission encounters between January 2016 and December 2018 and bronchiolitis diagnoses in the Pediatric Health Information System database. We excluded patients with any intensive care, stay >7 days, encounters in the preceding 30 days, chronic medical conditions, croup, pneumonia, or asthma. Guideline nonadherence was defined as receiving any of 5 tests or treatments: bronchodilators, chest radiographs, systemic steroids, antibiotics, and viral testing. Nonadherence outcomes were modeled by using mixed effects logistic regression with random effects for providers and hospitals. Adjusted odds ratio (aOR) >1 indicates greater likelihood of nonadherence.

RESULTS

A total of 198 028 encounters were included (141 442 ED and 56 586 admission), and nonadherence was 46.1% (ED: 40.2%, admissions: 61.0%). Nonadherence increased with patient age, with both ED and hospital providers being more likely to order tests and treatments for children 12 to 24 months compared with infants 1 ot 2 months (ED: aOR, 3.39; 95% confidence interval [CI], 3.20-3.60; admissions: aOR, 2.97; CI, 2.79-3.17]). Admitted non-Hispanic Black patients were more likely than non-Hispanic white patients to receive guideline nonadherent care (aOR, 1.16; CI, 1.10-1.23), a difference driven by higher use of steroids (aOR, 1.29; CI, 1.17-1.41) and bronchodilators (aOR, 1.39; CI, 1.31-1.48). Hospital effects were prominent for viral testing in ED and admission encounters (intraclass correlation coefficient of 0.35 and 0.32, respectively).

CONCLUSIONS

Multiple factors are associated with national bronchiolitis guideline nonadherence.

Racial and ethnic disparities in bronchiolitis management in freestanding children's hospitals

OBJECTIVE

Variation in bronchiolitis management by race and ethnicity within emergency departments (EDs) has been described in single-center and prospective studies, but large-scale assessments across EDs and inpatient settings are lacking. Our objective is to describe the association between race and ethnicity and bronchiolitis management across 37 U.S. freestanding children's hospitals from 2015 to 2018.

METHODS

Using the Pediatric Health Information System, we analyzed ED and inpatient visits from November 2015 to November 2018 of children with bronchiolitis 3 to 24 months old. Rates of use for specific diagnostic tests and therapeutic measures were compared across the following race/ethnicity categories: 1) non-Hispanic White (NHW), 2) non-Hispanic Black (NHB), 3) Hispanic, and 4) other. The subanalyses of ED patients only and children < 1 year old were performed. Mixed-effect logistic regression was performed to compare the adjusted odds of receiving specific test/treatment using NHW children as the reference group.

RESULTS

A total of 134,487 patients met inclusion criteria (59% male, 28% NHB, 26% Hispanic). Adjusted analysis showed that NHB children had higher odds of receiving medication associated with asthma (odds ratio [OR] = 1.27, 95% confidence interval [CI] = 1.22 to 1.32) and lower odds of receiving diagnostic tests (blood cultures, complete blood counts, viral testing, chest x-rays; OR = 0.78, 95% CI = 0.75 to 0.81) and antibiotics (OR = 0.58, 95% CI = 0.52 to 0.64) than NHW children. Hispanic children had lower odds of receiving diagnostic testing (OR = 0.94, 95% CI = 0.90 to 0.98), asthma-associated medication (OR = 0.92, 95% CI = 0.88 to 0.96), and antibiotics (OR = 0.74, 95% CI = 0.66 to 0.82) compared to NHW children.

CONCLUSION

NHB children more often receive corticosteroid and bronchodilator therapies; NHW children more often receive antibiotics and chest radiography. Given that current guidelines generally recommend supportive care with limited diagnostic testing and medical intervention, these findings among NHB and NHW children represent differing patterns of overtreatment. The underlying causes of these patterns require further investigation.

Reducing Chest Radiographs in Bronchiolitis Through High-Reliability Interventions

BACKGROUND AND OBJECTIVES

Bronchiolitis is a leading cause of pediatric hospitalization in the United States, resulting in significant morbidity and health care resource use. Despite American Academy of Pediatrics recommendations against obtaining chest radiographs (CXRs) for bronchiolitis, variation in care continues. Historically, clinical practice guidelines and educational campaigns have had mixed success in reducing unnecessary CXR use. Our aim was to reduce CXR use for children <2 years with a primary diagnosis of bronchiolitis, regardless of emergency department (ED) disposition or preexisting conditions, from 42.1% to <15% of encounters by March 2020.

METHODS

A multidisciplinary team was created at our institution in 2012 to standardize bronchiolitis care. Given success with higher reliability interventions in asthma, similar interventions affecting workflow were subsequently pursued with bronchiolitis, starting in 2017, by using quality improvement science methods. The primary outcome was the percent of bronchiolitis encounters with a CXR. The balancing measure was return visits within 72 hours to the ED. Statistical process control charts were used to monitor and analyze data obtained from an internally created dashboard.

RESULTS

From 2012 to 2020, our hospital had 12 120 bronchiolitis encounters. Preimplementation baseline revealed a mean of 42.1% for CXR use. Low reliability interventions, like educational campaigns, resulted in unsustained effects on CXR use. Higher reliability interventions were associated with sustained reductions to 23.3% and 18.9% over the last 4 years. There was no change in ED return visits.

CONCLUSIONS

High-reliability workflow redesign was more effective in translating American Academy of Pediatrics recommendations into sustained practice than educational campaigns.

Low-Value Diagnostic Imaging in Children with Medicaid

OBJECTIVES

To estimate rates and settings of low-value imaging among pediatric Medicaid beneficiaries and estimate the associated expenditures.

STUDY DESIGN

Retrospective longitudinal cohort study from 2014 to 2016 of children <18 years enrolled in Pennsylvania Medicaid. Outcomes were rates of low-value imaging for 5 conditions identified by diagnosis codes, healthcare settings of imaging performance, and cost based on paid amounts.

RESULTS

Of the 645 767 encounters for the 5 conditions, there were 37 525 (5.8%) low-value imaging services. Per 1000 encounters, there were 246.0 radiographs for bronchiolitis, 174.0 head computed tomography (CT) studies for minor head trauma, 155.0 and 33.3 neuroimaging studies for headache and simple febrile seizure, respectively, and 19.5 abdominal CT scans (without prior ultrasound examination) for abdominal pain. Rates of low-value imaging were highest in non-Hispanic White children and those in rural areas. In adjusted analysis, non-Hispanic White children were more likely to receive a CT scan for abdominal pain, and Black children were more likely to have imaging for bronchiolitis and minor head trauma. For individual conditions, up to 87.9% of low-value imaging (CT scan for minor head trauma) was in the emergency department (ED), with most imaging across all conditions occurring in nonpediatric EDs, up to 42.2% was in the outpatient setting (neuroimaging for headache), and up to 20.7% was during inpatient encounters (neuroimaging for febrile seizure). Outpatient and ED low-value imaging resulted in more than $7 million in Medicaid expenditures.

CONCLUSIONS

Among the studied conditions, more than 1 in 20 encounters included low-value imaging, mostly in nonpediatric EDs and for bronchiolitis, head trauma, and headache. Interventions are needed to decrease the future performance of these low-value services.

A behavioural approach to specifying interventions: what insights can be gained for the reporting and implementation of interventions to reduce antibiotic use in hospitals?

Background

Reducing unnecessary antibiotic exposure is a key strategy in reducing the development and selection of antibiotic-resistant bacteria. Hospital antimicrobial stewardship (AMS) interventions are inherently complex, often requiring multiple healthcare professionals to change multiple behaviours at multiple timepoints along the care pathway. Inaction can arise when roles and responsibilities are unclear. A behavioural perspective can offer insights to maximize the chances of successful implementation.

Objectives

To apply a behavioural framework [the Target Action Context Timing Actors (TACTA) framework] to existing evidence about hospital AMS interventions to specify which key behavioural aspects of interventions are detailed.

Methods

Randomized controlled trials (RCTs) and interrupted time series (ITS) studies with a focus on reducing unnecessary exposure to antibiotics were identified from the most recent Cochrane review of interventions to improve hospital AMS. The TACTA framework was applied to published intervention reports to assess the extent to which key details were reported about what behaviour should be performed, who is responsible for doing it and when, where, how often and with whom it should be performed.

Results

The included studies (n = 45; 31 RCTs and 14 ITS studies with 49 outcome measures) reported what should be done, where and to whom. However, key details were missing about who should act (45%) and when (22%). Specification of who should act was missing in 79% of 15 interventions to reduce duration of treatment in continuing-care wards.

Conclusions

The lack of precise specification within AMS interventions limits the generalizability and reproducibility of evidence, hampering efforts to implement AMS interventions in practice.

Reducing High-flow Nasal Cannula Overutilization in Viral Bronchiolitis

Supplemental Digital Content is available in the text.

Introduction:

Heated high-flow nasal cannula (HHFNC) therapy for bronchiolitis has become increasingly prevalent without evidence that this therapy impacts patient outcomes. Lack of criteria for appropriate use may lead to overutilization, resulting in increased costs without patient benefit. Our primary aim was to decrease use of HHFNC in patients with bronchiolitis over one season.

Methods:

Patients with Bronchiolitis younger than 2 years of age admitted to the Hospital Medicine Service were included in this study. Using the model for improvement framework, we identified key drivers for HHFNC overuse and revised our bronchiolitis protocol to include low-flow nasal cannula trials before HHFNC initiation. We compared preintervention HHFNC utilization (December 2018–April 2019) with postintervention HFNC utilization (December 2019–March 2020).

Results:

One hundred ninety patients met inclusion criteria, 98 of them in the preintervention cohort and 92 in the postintervention cohort. Overall, the median age was 9 months and 65% of patients were male. Our HHFNC utilization rate decreased from 62% (61/98) to 43% (40/92) in the postintervention period. Our SPC analysis suggested special cause variation based on 7 points below the preintervention mean.

Conclusions:

This QI intervention implementing a specified low-flow nasal cannula trial before the initiation of HHFNC shows promise in reducing overall HHFNC use. Future studies should focus on clear initiation and discontinuation criteria for HHFNC use in bronchiolitis.

[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.

The bronchiolitis severity score: An assessment of face validity, construct validity, and interobserver reliability

OBJECTIVE

To assess face validity, interobserver reliability, and the ability to discriminate escalations of care within 24-h of admission (late rescues) for the bronchiolitis severity score (BSS) for children hospitalized for acute bronchiolitis.

HYPOTHESES

The BSS will yield variable face validity, have clinically relevant interobserver reliability (kappa > 0.7), and distinguish late rescues during hospitalization.

METHODS

We performed a combined retrospective and prospective, mixed methods study where (1) interobserver agreement was prospectively assessed by overall and subcategory congruence (kappa) calculations, (2) face value were qualitatively assessed from aggregate questionnaire responses, and (3) construct validity for late rescues were assessed using receiver operator characteristic (ROC) curve analyses.

RESULTS

Face validity, assessed from 39 questionnaire respondents, were generally positive for BSS utility, reliability, and usability. The BSS exhibited weak interobserver reliability (kappa = 0.22, 95% confidence interval [CI]: 0.11-0.31) calculated from 72 sequential, blinded calculations. Retrospectively, 181 children less than 2 years of age admitted to the general pediatric ward for acute bronchiolitis from November 2017 to April 2019 were identified of which 18 (9.9%) experienced late rescues. Admission BSS values were no different for children with and without late rescues (6[3,6] vs. 4[3,6]; p = .09). An ROC curve analysis revealed an area under the curve of 0.61 (95% CI: 0.48-0.75; threshold ≥6 with sensitivity = 56%, specificity = 69%) for BSS to discriminate late rescues.

CONCLUSION

Although clinicians expressed favorable perceptions of BSS face and content validity, we noted weak interobserver reliability and limited construct validity. Further development and validation are needed to strengthen the BSS before routine use.

Reducing unnecessary antibiotic prescription through implementation of a clinical guideline on self-limiting respiratory tract infections

BACKGROUND

Clinical guidelines (CG) are used to reduce variability in practice when the scientific evidence is sparse or when multiple therapies are available. The development and implementation of evidence-based CG is intended to organize and provide the best available evidence to support clinical decision making in order to improve quality of care. Upper respiratory tract infections (URTI) are the leading cause of misuse of antibiotics and a CG may reduce the unnecessary antibiotic prescription.

METHODS

The aim of this quasi-experimental, before-after study was to analyze the short- and long-term effects of the implementation of a CG to decrease the rate of antibiotic prescription in URTI cases in the emergency department of a third level private hospital in Quito, Ecuador. The study included 444 patients with a main diagnosis of URTI. They were distributed in three groups: a baseline cohort 2011 (n = 114), a first post-implementation cohort 2011 (n = 114), and a later post-implementation cohort 2018 (n = 216). The implementation strategy consisted of five key steps: acceptance of the need for implementation of the CG, dissemination of the CG, an educational campaign, constant feedback, and sustainability of the strategy through continuous training.

RESULTS

The results of this study show a 42.90% of antibiotic prescription rate before the CG implementation. After the implementation of the CG, the prescription rate of antibiotics was significantly reduced by 24.5% (42.9% vs 18.4%, p<0.0001) and the appropriate antibiotic prescription rate was significantly increased by 44.2% (22.4% vs 66.6%, p<0.0001) in the first post-implementation cohort 2011. There was not a significant difference in antibiotic prescription rate and appropriate antibiotic prescription rate between two post-implementation cohorts: 18.4% vs 25.9% (p = 0.125) and 66.6% vs 50% (p = 0.191), respectively.

CONCLUSIONS

The implementation of CGs decreases the rate of antibiotic prescription in URTI cases. The results are remarkable after early implementation, but the effect persists over time. The emphasis must shift from guideline development to strategy implementation.

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.

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

We performed a quality improvement initiative to reduce unnecessary treatments for acute bronchiolitis (AB) in primary care (PC) and the referral paediatric emergency department (ED). The quality improvement initiative involved two seasons: 2016-2017 (preintervention) and 2017-2018 (postintervention). We distributed an evidence-based protocol, informative posters and badges with the slogan 'Bronchiolitis, less is more'. We also held interactive sessions, and paediatricians received weekly reports on bronchodilator prescription. The main outcome was the percentage of infants prescribed salbutamol. Secondary outcomes were epinephrine, antibiotic and corticosteroid prescription rates. Control measures were ED visit and hospitalisation rates, triage level, length of stay, intensive care admission and unscheduled returns with admission. We included 1878 ED and 1192 PC visits of which 855 (44.5%) and 534 (44.7%) occurred in the postintervention period, respectively. In the ED, salbutamol and epinephrine prescription rates fell from 13.8% (95% CI 11.8% to 16%) to 9.1% (95% CI 7.3% to 11.2%) (p<0.01) and 10.4% (95% CI 8.6% to 12.4%) to 9% (95% CI 7.2% to 11.1%) (n.s.), respectively. In PC, salbutamol, corticosteroid and antibiotic prescription rates fell from 38.3% (95% CI 34.6% to 42.0%) to 15.9% (95% CI 12.9% to 19.5%) (p<0.01), 12.9% (95% CI 10.5% to 15.7%) to 3.6% (95% CI 2.2% to 5.7%) (p<0.01) and 29.6% (95% CI 26.2% to 33.2%) to 9.5% (95% CI 7.2% to 12.5%) (p<0.01), respectively. No significant variations were noted in control measures. We safely decreased the use of unnecessary treatments for AB. Collaboration between PC and ED appears to be an important factor for success.

Resource Use and Outcomes of Pediatric Congenital Heart Disease Admissions: 2003 to 2016

Background

Children with congenital heart disease (CHD) are known to consume a disproportionate share of resources, yet there are limited data concerning trends in resource use and mortality among admitted children with CHD. We hypothesize that charges in CHD‐related admissions increased but that mortality improved over time.

Methods and Results

This study, including patients <18 years old with CHD, examined inpatient admissions from the nationally representative Kids' Inpatient Database from 2003 to 2016 in order to assess the frequency, medical complexity, and outcomes of CHD hospital admissions. A total of 859 843 admissions of children with CHD were identified. CHD admissions increased by 31.8% from 2003 to 2016, whereas overall pediatric admissions decreased by 13.4%. Compared with non‐CHD admissions, those with CHD were more likely to be <1 year of age (80.5% versus 63.3%), and to have ≥1 complex chronic condition (39.7% versus 9.3%). For CHD admissions, mortality was higher (2.97% versus 0.31%) and adjusted median charges greater ($48 426 [interquartile range (IQR), $11.932–$161 048] versus $4697 [IQR, $2551–$12 301]) (P<0.0001 for all). Among CHD admissions, whereas adjusted median charges increased from $35 577 (IQR, $9303–$110 439) to $61 696 (IQR, $15 212–$219 237), mortality decreased from 3.2% to 2.7% (P for trend <0.0001). CHD admissions accounted for an increased proportion of all inpatient deaths, from 18.0% in 2003 to 24.5% in 2016.

Conclusions

Children admitted with CHD are 10 times more likely to die than those without CHD and have higher charges. Although the rate of mortality in CHD admissions decreased, children with CHD accounted for an increasing proportion of all pediatric inpatient deaths. Effective resource allocation is critical to optimize outcomes in these high‐risk patients.

Trends Over Time in Use of Nonrecommended Tests and Treatments Since Publication of the American Academy of Pediatrics Bronchiolitis Guideline

IMPORTANCE

Acute viral bronchiolitis is a common and costly pediatric condition for which clinical practice guidelines discourage use of diagnostic tests and therapies.

OBJECTIVE

To evaluate trends over time for use of nonrecommended services for bronchiolitis since publication of the American Academy of Pediatrics clinical practice guideline on bronchiolitis (originally published in October 2006 and updated in November 2014).

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted using interrupted time-series regression analysis adjusting for the hospital providing service, patient demographic characteristics, and payer, with 2014 guideline update publication as the event point. Included patients were children younger than 2 years old discharged from the emergency department (ED) or hospital inpatient setting with a primary diagnosis of bronchiolitis at US Children's Hospitals contributing data to the Pediatric Health Information Systems database. Data were analyzed from June through December 2020.

MAIN OUTCOMES AND MEASURES

Rates of nonrecommended tests (ie, chest radiography, viral testing, and complete blood cell count) and treatments (ie, bronchodilators, corticosteroids, antibiotics) were measured.

RESULTS

Among 602 375 encounters involving children with a primary diagnosis of bronchiolitis, 404 203 encounters (67.1%) were ED discharges and 198 172 encounters (32.9%) were inpatient discharges; 468 226 encounters (77.7%) involved children younger than 12 months, and 356 796 encounters (59.2%) involved boys. In the period after initial guideline publication (ie, November 2006 to November 2014), a negative use trajectory was found in all measures except viral testing in the ED group. Using the 2014 guideline update as the event point, several measures showed decreased use between study time periods. The greatest decrease was in bronchodilator use, which changed by -13.5 percentage points in the ED group (95% CI, -15.2 percentage points to -11.8 percentage points) and -11.3 percentage points in the inpatient group (95% CI, -13.1 percentage points to -9.4 percentage points). In the period after the 2014 guideline update (ie, December 2014 to December 2019), bronchodilators also showed the greatest change in usage trajectory, steepening more than 2-fold in both groups. In the ED group, the negative trajectory steepened from -0.11% monthly (95% CI, -0.13% to -0.09%) in the first guideline period to a new mean monthly slope of -0.26% (95% CI, -0.30% to -0.23%). In the inpatient group, the mean monthly slope steepened from -0.08% (95% CI, -0.10 to -0.05%) to -0.26% (95% CI, 0.30% to -0.22%). Length of stay decreased from 2.0 days (95% CI, 1.9 days to 2.1 days) to 1.7 days (95% CI, 1.7 days to 1.8 days). Hospital admission rate decreased from 18.0% (95% CI, 13.8% to 22.2%) to 17.8% (95% CI, 13.6 to 22.1%).

CONCLUSIONS AND RELEVANCE

This cohort study with interrupted time-series analysis found that use of most nonrecommended bronchiolitis services decreased continuously after 2006. The rate of decline in bronchodilator use increased more than 2-fold after the 2014 guideline update. These findings support potential associations of practice guidelines with improved bronchiolitis care.

The Association of Seasonality With Resource Use in a Large National Cohort of Infants With Bronchiolitis

OBJECTIVES

Examine the degree of seasonal variation in nonrecommended resource use for bronchiolitis management subsequent to publication of the American Academy of Pediatrics (AAP) 2014 guidelines.

METHODS

We performed a multicenter retrospective cohort study using the Pediatric Health Information System database, examining patients aged 1 to 24 months, diagnosed with bronchiolitis between November 2015 and November 2018. Exclusions included presence of a complex chronic condition, admission to the PICU, hospital stay >10 days, or readmission. Primary outcomes were use rates of viral testing, complete blood count, blood culture, chest radiography, antibiotics, albuterol, and systemic steroids. Each hospital's monthly bronchiolitis census was aggregated into hospital bronchiolitis census quartiles. Mixed-effect logistic regression was performed, comparing the primary outcomes between bronchiolitis census quartiles, adjusting for patient age, race, insurance, hospitalization status, bacterial coinfection, time since publication of latest AAP bronchiolitis guidelines, and clustering by site.

RESULTS

In total, 196 902 bronchiolitis patient encounters across 50 US hospitals were analyzed. All hospitals followed a similar census pattern, with peaks during winter months and nadirs during summer months. Chest radiography, albuterol, and systemic steroid use were found to significantly increase in lower bronchiolitis census quartiles, whereas rates of viral testing significantly decreased. No significant variation was found for complete blood count testing, blood culture testing, or antibiotic use. Overall adherence with AAP guidelines increased over time.

CONCLUSIONS

Resource use for patients with bronchiolitis varied significantly across hospital bronchiolitis census quartiles despite adjusting for potential known confounders. There remains a need for greater standardization of bronchiolitis management.

Inappropriate antibiotic prescribing for acute bronchiolitis in Colombia: a predictive model

Introduction

Acute bronchiolitis is the leading cause of hospitalization in the pediatric population. The inappropriate prescription of antibiotics in acute bronchiolitis is associated with bacterial resistance, higher costs, and risk of adverse effects in this population. The objective of this work is to develop a predictive model of inappropriate use of antibiotics in children with acute bronchiolitis in Colombia.

Methods

A retrospective cohort study was conducted in patients under 2 years of age with a diagnosis of acute bronchiolitis from two hospitals in Rionegro, Colombia. To identify factors independently associated with inappropriate use of antibiotics, we used logistic regression and estimated odds ratios (ORs). To assess discrimination, area under the curve (AUC) was estimated with a 95% confidence interval and plotted using AUC–ROC plots. To correct sampling bias of variance parameters and to evaluate the internal validity of the model, repeated curved validation “tenfold cross-validation” was used, comparing the area under the ROC curve obtained in the repetitions with that observed in the model

Results

A total of 415 patients were included. 142 patients (34.13%) had a prescription of some antibiotic during their hospital stay. In 92 patients (64.78%, 95% CI 56.3 to 72.6%) the prescription of antibiotics was classified as inappropriate. Age older than 1 year, chest retractions, temperature between 37.5 °C and 38.5 °C and leukocyte count between 10,000 and 15,000 million/mm³ were the predictive variables of inappropriate use of medications in this population.

Conclusion

The presence of fever between 37.5 °C and 38.5 °C, leukocytosis between 10,000 and 15,000 million/mm³, and age older than 1 year and presence of chest retractions, should alert the physician regarding the high risk of inappropriate prescription of antibiotics. Patients with acute bronchiolitis with a score on our scale greater than 2 should be carefully evaluated regarding the need for the use of antibiotics, if prescribed.

Cost-effectiveness analysis of phenotypic-guided versus guidelines-guided bronchodilator therapy in viral bronchiolitis

OBJECTIVES

Although recent evidence suggests that management of viral bronchiolitis requires something other than guidelines-guided therapy, there is a lack of evidence supporting the economic benefits of phenotypic-guided bronchodilator therapy for treating this disease. The aim of the present study was to compare the cost-effectiveness of phenotypic-guided versus guidelines-guided bronchodilator therapy in infants with viral bronchiolitis.

METHODS

A decision analysis model was developed to compare the cost-effectiveness of phenotypic-guided versus guidelines-guided bronchodilator therapy in infants with viral bronchiolitis. Phenotypic-guided bronchodilator therapy was defined as the administration of albuterol in infants exhibiting a profile of increased likelihood of response to bronchodilators. The effectiveness parameters and costs of the model were obtained from systematic reviews of the literature with meta-analyses and electronic medical records. The main outcome was the avoidance of hospital admission after initial care in the emergency department.

RESULTS

Compared to guidelines-guided strategy, treating patients with viral bronchiolitis with the phenotypic-guided bronchodilator therapy strategy was associated with lower total costs (US$250.99; 95% uncertainty interval [UI]: US$184.37 to $336.51 vs. US$263.46; 95% UI: US$189.81 to $349.19 average cost per patient) and a higher probability of avoidance of hospital admission (0.7902; 95% UI: 0.7315-0.8356 vs. 0.7638; 95% UI: 0.7062-0.8201), thus leading to dominance. Results were robust to deterministic and probabilistic sensitivity analyses.

CONCLUSIONS

Compared to guidelines-guided strategy, treating infants with viral bronchiolitis using the phenotypic-guided bronchodilator therapy strategy is a more cost-effective strategy, because it involves a lower probability of hospital admission at lower total treatment costs.

Associations Between Quality Measures and Outcomes for Children Hospitalized With Bronchiolitis

OBJECTIVES

To use adherence to the Pediatric Respiratory Illness Measurement System (PRIMES) indicators to evaluate the strength of associations for individual indicators with length of stay (LOS) and cost for bronchiolitis.

METHODS

We prospectively enrolled children with bronchiolitis at 5 children's hospitals between July 1, 2014, and June 30, 2016. We examined associations between adherence to each individual PRIMES indicator for bronchiolitis and LOS and cost. Sixteen indicators were included, 9 "overuse" indicators for care that should not occur and 7 "underuse" indicators for care that should occur. We performed mixed effects linear regression to examine the association between adherence to each individual indicator and LOS (hours) and cost (dollars). All models controlled for patient demographics, patient complexity, and hospital.

RESULTS

We enrolled 699 participants. The mean age was 8 months; 56% were male, 38% were white, and 63% had public insurance. Three indicators were significantly associated with shorter LOS and lower cost. All 3 indicators were overuse indicators and related to laboratory testing: no blood cultures (adjusted mean difference in LOS: -24.3 hours; adjusted mean cost difference: -$731, P < .001), no complete blood cell counts (LOS: -17.8 hours; cost: -$399, P < .05), and no respiratory syncytial virus testing (LOS: -16.6 hours; cost: -$272, P < .05). Two underuse indicators were associated with higher cost: documentation of oral intake at discharge ($671, P < .01) and documentation of hospital follow-up ($538, P < .05).

CONCLUSIONS

A subset of PRIMES quality indicators for bronchiolitis are strongly associated with improved outcomes and can serve as important measures for future quality improvement efforts.

Use of interrupted time series methods in the evaluation of health system quality improvement interventions: a methodological systematic review

BACKGROUND

When randomisation is not possible, interrupted time series (ITS) design has increasingly been advocated as a more robust design to evaluating health system quality improvement (QI) interventions given its ability to control for common biases in healthcare QI. However, there is a potential risk of producing misleading results when this rather robust design is not used appropriately. We performed a methodological systematic review of the literature to investigate the extent to which the use of ITS has followed best practice standards and recommendations in the evaluation of QI interventions.

METHODS

We searched multiple databases from inception to June 2018 to identify QI intervention studies that were evaluated using ITS. There was no restriction on date, language and participants. Data were synthesised narratively using appropriate descriptive statistics. The risk of bias for ITS studies was assessed using the Cochrane Effective Practice and Organisation of Care standard criteria. The systematic review protocol was registered in PROSPERO (registration number: CRD42018094427).

RESULTS

Of 4061 potential studies and 2028 unique records screened for inclusion, 120 eligible studies assessed eight QI strategies and were from 25 countries. Most studies were published since 2010 (86.7%), reported data using monthly interval (71.4%), used ITS without a control (81%) and modelled data using segmented regression (62.5%). Autocorrelation was considered in 55% of studies, seasonality in 20.8% and non-stationarity in 8.3%. Only 49.2% of studies specified the ITS impact model. The risk of bias was high or very high in 72.5% of included studies and did not change significantly over time.

CONCLUSIONS

The use of ITS in the evaluation of health system QI interventions has increased considerably over the past decade. However, variations in methodological considerations and reporting of ITS in QI remain a concern, warranting a need to develop and reinforce formal reporting guidelines to improve its application in the evaluation of health system QI interventions.

Trends and Variation in Care and Outcomes for Children Hospitalized With Acute Gastroenteritis

OBJECTIVES

Assess trends in inpatient acute gastroenteritis (AGE) management across children's hospitals and identify elements of AGE management associated with resource use.

METHODS

We examined inpatient stays for children 6 months to 18 years hospitalized with AGE from 2009 to 2018 using the Pediatric Health Information System database. We characterized demographics, hospital-level resource use (ie, medications, laboratories, and imaging), and outcomes (ie, cost per case, 14-day revisit rates, and length of stay [LOS]). We compared demographic characteristics and resource use between 2009 to 2013 and 2014 to 2018 using χ2 and Wilcoxon rank-sum tests. We grouped hospitals on the basis of 2009 use of each resource and trended use over time using logistic regression. Annual change in mean cost and LOS were estimated by using models of log-transformed data.

RESULTS

Across 32 354 hospitalizations at 38 hospitals, there was a high use of electrolyte testing (85.4%) and intravenous fluids (84.1%) without substantial changes over time. There were significant reductions in the majority of laboratory, medication, and imaging resources across hospitals over the study period. The most notable reductions were for rotavirus and stool testing. Many hospitals saw a decrease in LOS, with only 3 noting an increased revisit rate. Reductions in cost per case over time were most associated with decreases in imaging, laboratory testing, and LOS.

CONCLUSIONS

Significant variation in resource use for children hospitalized with AGE coupled with high use of resources discouraged in AGE guidelines highlights potential opportunities to improve resource use that may be addressed in future AGE guidelines and quality improvement initiatives.

Pediatricians' Attitude in Management of Acute Bronchiolitis: Did Guidelines Overcome Practices?

Background: Acute bronchiolitis is one of the most common diseases of early childhood. There are many recent changes in the treatment of acute bronchiolitis. The aim of this study is to evaluate treatment approaches to acute bronchiolitis among clinicians and to observe compliance with clinical guidelines. Materials and Methods: Our study was designed as a multicenter cross-sectional descriptive study. A cohort of pediatric residents, fellows, and attendants were surveyed with a questionnaire including general and occupational characteristics of pediatricians and treatment choices in acute bronchiolitis. Results: A total of 713 questionnaires were collected. Most commonly applied treatment among pediatricians was inhaled salbutamol, followed by intravenous hydration, hypertonic saline, and inhaled steroid. Most commonly preferred treatment in the management of mild bronchiolitis was oral hydration and inhaled salbutamol in severe bronchiolitis. Conclusion: Although recent guidelines for the treatment of acute bronchiolitis does not support the use of many different therapies, pediatricians still tend to use them, especially bronchodilators, corticosteroids, and antibiotics.

Management of severe bronchiolitis: impact of NICE guidelines

OBJECTIVE

To understand the impact of the National Institute for Health and Care Excellence (NICE) bronchiolitis guidelines on the management of children referred to paediatric intensive care unit (PICU) with bronchiolitis.

DESIGN AND SETTING

Data were collected on all children referred to a regional PICU transport service with the clinical diagnosis of bronchiolitis during the winter prior to the NICE consultation period (2011-2012) and during the winter after publication (2015-2016). Management initiated by the referring hospital was assessed.

RESULTS

There were 165 infants referred with bronchiolitis in epoch 1 and 187 in epoch 2. Nebuliser use increased from 28% in epoch 1 to 53% in epoch 2. Increased use of high-flow nasal cannula oxygen and reduction in continuous positive airway pressure use were observed. The use of antibiotics did not change between epochs.

CONCLUSION

The use of nebulised therapies has increased in the management of severe bronchiolitis despite national guidance to the contrary.

Language Barriers and the Management of Bronchiolitis in a Pediatric Emergency Department

OBJECTIVE

Language barriers may influence the management of pediatric emergency department (PED) patients who may not align with evidence-based guidelines from the American Academy of Pediatrics. Our objective was to determine if a family's preferred language of Spanish versus English was associated with differences in management of bronchiolitis in the PED.

METHODS

We conducted a retrospective study of children ≤2 years old diagnosed with bronchiolitis in a PED over a 7-year period. Rates of PED testing, interventions, and disposition among children whose families' preferred language was Spanish were compared to children whose families' preferred language was English. Primary outcomes were frequencies of chest x-ray and bronchodilator orders. Secondary outcomes were diagnostic testing, medication orders, and disposition. Logistic regression was used to calculate adjusted odds ratios after controlling for age, emergency severity index, prior visit, and nesting within attending physicians.

RESULTS

A total of 13,612 encounters were included. Spanish-speaking families were more likely to have chest x-rays (35.8% vs 26.7%, P < .0001; adjusted odds ratio [aOR] 1.5; 95% confidence interval [CI] 1.2-1.9), complete blood counts (8.2% vs 4.9%, P < .005; aOR 1.7; 95% CI 1.2-2.5), and blood cultures ordered (8.1% vs 5.0%, P < .05; aOR 1.7; 95% CI 1.2-2.4). No other differences in bronchodilators, medication orders, or disposition were found between the 2 groups.

CONCLUSIONS

Among children diagnosed with bronchiolitis, Spanish-speaking families were more likely to have chest x-rays, complete blood counts, and blood cultures ordered compared to English-speaking families. Further research on how clinical practice guidelines and equity-focused guidelines can impact disparities in diagnostic testing within the PED is warranted.

Impact of the Choosing Wisely® Campaign Recommendations for Hospitalized Children on Clinical Practice: Trends from 2008 to 2017

BACKGROUND

The Choosing Wisely^® Campaign (CWC) was launched in 2012. Five recommendations to reduce the use of "low-value" services in hospitalized children were published in 2013.

OBJECTIVES

The aim of this study was to estimate the frequency and trends of utilization of these services in tertiary children's hospitals five years before and after the publication of the recommendations.

METHODS

We conducted a retrospective, longitudinal analysis of hospitalizations to 36 children's hospitals from 2008 to 2017. The "low-value" services included (1) chest radiograph (CXR) for asthma, (2) CXR for bronchiolitis, (3) relievers for bronchiolitis, (4) systemic steroids for lower respiratory tract infection (LRTI), and (5) acid suppressor therapy for uncomplicated gastroesophageal reflux (GER). We estimated the annual percentages of the use of these services after risk adjustment, followed by an interrupted time series (ITS) analysis to compare trends before and after the publication of the recommendations.

RESULTS

The absolute decreases in utilization were 36.6% in relievers and 31.5% in CXR for bronchiolitis, 24.1% in acid suppressors for GER, 20.8% in CXR for asthma, and 2.9% in steroids for LRTI. Trend analysis showed that one "low-value" service declined significantly immediately (use of CXR for asthma), and another decreased significantly over time (relievers for bronchiolitis) after the CWC.

CONCLUSIONS

There was some decrease in the utilization of "low-value" services from 2008 to 2017. Limited changes in trends occurred after the publication of the recommendations. These findings suggest a limited impact of the CWC on clinical practice in these areas. Additional interventions are required for a more effective dissemination of the CWC recommendations for hospitalized children.

Bronchiolitis at a specialist paediatric centre: The electronic medical record helps to evaluate low-value care

AIM

Low-value care (LVC) is common. We aimed, using infants presenting to a major tertiary paediatric hospital with bronchiolitis between April 2016 and July 2018, to: (i) assess rates of chest X-ray (CXR) and medication use; (ii) identify associated factors; and (iii) measure the harm of not performing these practices.

METHODS

We extracted data from the electronic medical record for all children aged 1-12 months given a diagnosis of bronchiolitis in the emergency department. Factors potentially associated with LVC practices were extracted, including patient demographics, ordering physician characteristics, order indication, medications prescribed and admission ward. To assess for harm, a radiologist, blinded to CXR indication, reviewed all CXRs ordered over the winter of 2017 for infants with bronchiolitis.

RESULTS

A CXR was ordered for 439 (11.2%) infants, most commonly to rule out consolidation and collapse (65%). CXRs were more likely to be ordered for admitted infants (40.9% admitted to the general medical ward), and 62% were ordered by emergency department staff. Salbutamol was prescribed for 9.3% (n = 199). Amongst those who had a CXR, 28% were prescribed an antibiotic compared to 2.1% for those who did not. In an audit of 98 CXRs ordered over the winter of 2017, there were no CXR findings that meaningfully affected patient outcomes.

CONCLUSION

Using electronic medical record data, we found that CXR and medication use in bronchiolitis were higher than expected given our hospital guideline advice. Future research needs to understand why and develop interventions to reduce LVC.

Bronchiolitis clinical practice guidelines implementation: surveillance study of hospitalized children in Jordan

INTRODUCTION

Bronchiolitis is a leading cause of hospital admissions and death in young children. Clinical practice guidelines (CPG) to diagnose and manage bronchiolitis have helped healthcare providers to avoid unnecessary investigations and interventions and to provide evidence-based treatment. Aim of this study is to determine the effect of implementing CPG for the diagnosis and management of bronchiolitis in a tertiary hospital in Jordan.

METHODS

The study compared children (age <24 months) diagnosed with bronchiolitis and who required admission to King Abdullah University Hospital in Irbid during the winter of 2017 (after CPG implementation) and age-matched children admitted in the winter of 2016. The proportion of patients receiving diagnostic tests and treatments in the two groups were compared.

RESULTS

Eighty-eight and 91 patients were diagnosed with bronchiolitis before and after CPG implementation, respectively. Respiratory syncytial virus rapid antigen detection testing decreased after CPG implementation [n=64 (72.7%) vs n=46 (50.5%), p=0.002]. However, there was no significant change in terms of other diagnostic tests. The use of nebulized salbutamol [n=44 (50%) vs n=29 (31.9%), p=0.01], hypertonic saline [n=39 (44.3%) vs n=8 (8.8%), p<0.001], and inappropriate antibiotics [n=31 (35.2%) vs n=15 (16.5%), p=0.004] decreased after CPG implementation. There was no difference in mean LOS (standard deviation; SD) between the pre- and post-CPG groups [3.5(2) vs 4 (3.4) days, p=0.19]. The mean cost of stay (SD) was 449.4 (329.1) US dollars for pre-CPG compared to 507.3 (286.1) US dollars for the post-CPG group (p=0.24).

CONCLUSION

We observed that the implementation of CPG for bronchiolitis diagnosis and management helped change physicians' behavior toward evidence-based practices. However, adherence to guidelines must be emphasized to improve practices in developing countries, focusing on the rational use of diagnostic testing, and avoiding use of unnecessary medications when managing children with a diagnosis of bronchiolitis.

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

BACKGROUND AND OBJECTIVES

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.

METHODS

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.

RESULTS

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).

CONCLUSIONS

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.

Management of bronchiolitis in Portugal, 2000-2015: Do guidelines have an impact?

BACKGROUND

Several studies report an excessive use of diagnostic tests and procedures in bronchiolitis, not supported by guidelines.

OBJECTIVES

We aimed to evaluate medical interventions in children hospitalized with bronchiolitis in public Portuguese hospitals, from 2000 to 2015, to evaluate the impact of the national guideline, published in December 2012, and assess variations between regions.

METHODS

Data was collected retrospectively from an administrative database that contains all hospitalizations in mainland public hospitals. Cases were selected using the ICD-9-CM codes 466.11 (bronchiolitis due to respiratory syncytial virus) and 466.19 (bronchiolitis due to other infectious organisms), in children under 2 years of age. For statistical analysis we used the χ² test and logistic regression.

RESULTS

In the 80 491 hospitalizations due to bronchiolitis, we found a high mean use rate of nonrecommended diagnostic and treatment procedures: chest x-ray (66.5%), blood analysis (56.5%) and respiratory secretions analysis (12.7%); nebulized therapy (83.5%), intravenous (IV) corticosteroids (24.2%), IV antibiotics (26.0%), electrolytes infusion (37.6%), and chest physiotherapy (20.4%). Over time, there was a gradual change in attitudes (P_trend  < .001), with significant variation between regions. Center region registered the lowest mean rates of routinely nonrecommended procedures.

CONCLUSIONS

In this first national study, rates of the nonrecommended diagnostic and treatment attitudes in bronchiolitis were higher than desirable, although there was a modest decreasing trend in their use over time. The observed variations were mainly dependent on the region, with no clear impact of the national guideline in attitude changing, highlighting the need for more active measures.

Targeted Education Across Clinical Settings Improves Adherence to Evidence-Based Interventions for Bronchiolitis

Bronchiolitis remains a leading cause of hospitalization of infants. Despite evidence-based recommendations, wide variation in practice remains. A pre-post educational intervention was implemented to improve adherence to bronchiolitis guidelines in emergency and inpatient settings. Among children meeting inclusion criteria (136 pre-intervention, 185 post-intervention), emergency department (ED) bronchodilator use decreased by 64% (P < .001). Steroid use decreased by 71% (P = .002). There was no difference in viral testing, antibiotic use, or chest radiograph acquisition. No differences were seen in the inpatient setting. There was no difference in rate of intensive care unit transfer or length of stay. Post-intervention, children were less likely to receive a bronchodilator in the ED (odds ratio [OR] = 0.15, P < .001). Children with a family history of asthma were more likely to receive a bronchodilator in the ED (OR = 4.25, P < .001). Targeted education across settings contributed to reducing bronchodilator use in the ED. Family history appeared to influence medical decision making.

Choosing Wisely Campaign: Report Card and Achievable Benchmarks of Care for Children's Hospitals

OBJECTIVES

In 2013, the Society of Hospital Medicine (SHM) released 5 pediatric recommendations for the Choosing Wisely Campaign (CWC). Our goals were to develop a report card on the basis of those recommendations, calculate achievable benchmarks of care (ABCs), and analyze performance among hospitals participating in the Pediatric Health Information System.

METHODS

Children hospitalized between January 2013 and September 2015 from 32 Pediatric Health Information System hospitals were studied. The quality metrics in the report card included the use of chest radiograph (CXR) in asthma and bronchiolitis, bronchodilators in bronchiolitis, systemic corticosteroids in lower respiratory tract infections (LRTI), and acid suppression therapy in gastroesophageal reflux (GER). ABCs were calculated for each metric.

RESULTS

Calculated ABCs were 22.3% of patients with asthma and 19.8% of patients with bronchiolitis having a CXR, 17.9% of patients with bronchiolitis receiving bronchodilators, 5.5% of patients with LRTIs treated with systemic corticosteroids, and 32.2% of patients with GER treated with acid suppressors. We found variation among hospitals in the use of CXR in asthma (median: 34.7%, interquartile range [IQR]: 28.5%-45.9%), CXR in bronchiolitis (median: 34.4%, IQR: 27.9%-49%), bronchodilators in bronchiolitis (median: 55.4%, IQR: 32.3%-64.9%), and acid suppressors in GER (median: 59.4%, IQR: 49.9%-71.2%). Less variation was noted in the use of systemic corticosteroids in LRTIs (median: 13.5%, IQR: 11.1%-17.9%).

CONCLUSIONS

A novel report card was developed on the basis of the SHM-CWC pediatric recommendations, including ABCs. We found variance in practices among institutions and gaps between hospital performances and ABCs. These findings represent a roadmap for improvement.

Pediatric Inpatient Antimicrobial Stewardship Program Safely Reduces Antibiotic Use in Patients with Bronchiolitis Caused by Respiratory Syncytial Virus: A Retrospective Chart Review

Bronchiolitis is a common lower respiratory tract illness in young children often caused by the respiratory syncytial virus (RSV). Antimicrobials are not recommended in infants with bronchiolitis unless there is strong evidence that a bacterial coinfection exists.

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

Objectives

To describe variations in the monitoring, treatment, and discharge of children hospitalized with bronchiolitis among physicians across Canadian paediatric teaching hospitals.

Methods

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.

Results

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).

Conclusion

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.

Assessing physical and respiratory distress in children with bronchiolitis admitted to a community hospital emergency department: A retrospective chart review

Introduction

Bronchiolitis is a leading cause of infant hospitalization with wide variation in its diagnosis and management, especially in smaller community hospitals. The objective of this study is to describe children admitted to a community-based hospital emergency department (ED) for bronchiolitis and explore alternate assessments of illness severity.

Methods

A retrospective chart review (January to September 2014) of 100 children, < 2 years old and meeting International Classification of Diseases 10 for bronchiolitis. Outcomes included demographics, symptoms, and interventions. In addition, the Respiratory Distress Assessment Instrument (RDAI) score was calculated using documented assessments of wheezing and retractions. Descriptive and comparative statistics were completed with p < 0.05 considered significant.

Results

The mean (standard deviation) age 10.6 (8.4) months, n = 41 females. Sixty-seven percent had a chest X-ray (CXR), 17% oral antibiotics, 65% bronchodilators, and 19% oral steroids; 19% were admitted in hospital. There was a significant difference in RDAI score between those given oral antibiotics (mean (95% CI), 6.35 (4.96–7.75)) versus not (4.70 (4.20–5.20)), p = 0.01. Those who received a CXR had a significantly higher oxygen flowrate (1.4 (0.6–2.1) litres per minute (lpm)) and worse physical appearance (tri-pod position, head bobbing) versus those who did not (0.15 (–0.05 to 0.35) lpm), p = 0.002 and p = 0.04, respectively.

Conclusions

A large number of children admitted to a community-based ED for bronchiolitis received unnecessary CXR and medications. Assessing physical and respiratory distress may be more effective at determining illness severity compared with radiological or laboratory testing. Local clinical practice guidelines may aid in optimal management of bronchiolitis for community-based EDs.

Pharmacotherapy in bronchiolitis at discharge from emergency departments within the Pediatric Emergency Research Networks: a retrospective analysis

BACKGROUND

Clinical guidelines advise against pharmacotherapy in bronchiolitis. However, little is known about global variation in prescribing practices for bronchiolitis at discharge from emergency departments. We aimed to evaluate global variation in prescribing practice (ie, inhaled salbutamol, or oral or inhaled corticosteroids) for infants with bronchiolitis at discharge from emergency departments.

METHODS

We did a planned secondary analysis of a multinational, retrospective cohort study of the Pediatric Emergency Research Networks. Previously healthy infants (aged <12 months) who were discharged with bronchiolitis between Jan 1 and Dec 31, 2013 from 38 emergency departments in Australia and New Zealand, Canada, Spain and Portugal, the UK and Ireland, and the USA were included. The primary outcome was pharmacotherapy prescription at discharge from the emergency department. Secondary outcomes were revisits to the emergency department or hospitalisations for bronchiolitis within 21 days of discharge.

FINDINGS

Of 1566 infants discharged from the emergency department, 317 (20%) were prescribed pharmacotherapy. Corticosteroid prescriptions were infrequent, ranging from 0% (0 of 68 infants) in Spain and Portugal to 6% (25 of 452) in the USA. Salbutamol prescriptions ranged from 5% (22 of 432) in the UK and Ireland to 32% (146 of 452) in the USA. Compared with the UK and Ireland, the odds of prescription of pharmacotherapy were increased in Spain and Portugal (odds ratio [OR] 9·22, 95% CI 1·70-49·96), the USA (8·20, 2·79-24·11), Canada (5·17, 1·61-16·67), and Australia and New Zealand (1·21, 0·36-4·10). After adjustment for clustering by site, pharmacotherapy at discharge was associated with older age (per 1 month increase; OR 1·23, 95% CI 1·16-1·30), oxygen saturation (per 1% decrease from 100%; 1·09, 1·01-1·18), chest retractions (1·88, 1·26-2·79), network (p=0·00050), and site (p<0·00090). 303 (19%) of 1566 infants returned to the emergency department and 129 (43%) of 303 were hospitalised. Discharge pharmacotherapy was not associated with revisits (p=0·55) or subsequent hospitalisations (p=0·50).

INTERPRETATION

Use of ineffective medications in infants with bronchiolitis at discharge from emergency departments is common, with large differences in prescribing practices between countries and emergency departments. Enhanced knowledge translation and deprescribing efforts are needed to optimise and unify the management of bronchiolitis.

FUNDING

None.

Emergency Department Management of Bronchiolitis in the United States

OBJECTIVE

The aim of this study was to examine differences between general and pediatric emergency departments (PEDs) in adherence to the American Academy of Pediatrics bronchiolitis management guidelines.

METHODS

We conducted a nationally representative study of ED visits by infants younger than 24 months with bronchiolitis from 2002 to 2011 using the National Hospital Ambulatory Medical Care Survey. Diagnostic testing (complete blood counts, radiographs) and medication use (albuterol, corticosteroids, antibiotics and intravenous fluids) in general emergency departments (GEDs) were compared with those in PEDs before and after 2006 American Academy of Pediatrics guideline publication. Weighted percentages were compared, and logistic regression evaluated the association between ED type and resource use.

RESULTS

Of more than 2.5 million ED visits for bronchiolitis from 2002 to 2011, 77.3% occurred in GEDs. General emergency departments were more likely to use radiography (62.7% vs 42.1%; adjusted odds ratio [aOR], 2.4; 95% confidence interval [CI], 1.4-4.1), antibiotics (41.3% vs 18.8%; aOR, 2.8; 95% CI, 1.5-5.2), and corticosteroids (24.3% vs 12.5%; aOR, 2.1; 95% CI, 1.0-4.5) compared with PEDs. Compared with preguideline, after guideline publication PEDs had a greater decrease in radiography use (-19.7%; 95% CI, -39.3% to -0.03%) compared with GEDs (-12.2%; 95% CI, -22.3% to -2.1%), and PEDs showed a significant decline in corticosteroid use (-12.4%; 95% CI, -22.1% to -2.8%), whereas GEDs showed no significant decline (-4.6%; 95% CI, -13.5% to 4.3%).

CONCLUSIONS

The majority of ED visits for bronchiolitis in the United States occurred in GEDs, yet GEDs had increased use of radiography, corticosteroids, and antibiotics and did not show substantial declines with national guideline publication. Given that national guidelines discourage the use of such tests and treatments in the management of bronchiolitis, efforts are required to decrease ED use of these resources in infants with bronchiolitis, particularly in GEDs.

Timely Data for Targeted Quality Improvement Interventions: Use of a Visual Analytics Dashboard for Bronchiolitis

BACKGROUND

Standard methods for obtaining data may delay quality improvement (QI) interventions including for bronchiolitis, a common cause of childhood hospitalization.

OBJECTIVE

To describe the use of a dashboard in the context of a multifaceted QI intervention aimed at reducing the use of chest radiographs, bronchodilators, antibiotics, steroids, and viral testing in patients with bronchiolitis.

METHODS

This QI initiative took place at Children's Minnesota, a large, not-for-profit children's health care organization. A multidisciplinary bronchiolitis workgroup developed a local clinical guideline and order-set. Delays in obtaining baseline data prompted a pediatric hospitalist and information technology specialist to modify a vendor's dashboard to display data related to bronchiolitis guideline metrics. Patients 2 months to 2 years old with a bronchiolitis emergency department (ED)/inpatient encounter in the period October 1, 2014 to April 30, 2018 were included. The primary outcome was a functioning dashboard; a process measure was the percentage of ED clinician logins. Outcome measures included the percent use of guideline metrics (e.g., bronchodilators) displayed on statistical process control charts (ED vs. inpatient). Balancing measures included length of stay, charge ratios, and hospital revisits.

RESULTS

A workgroup (formed October 2015) implemented a bronchiolitis order-set and guideline (February 2016) followed by a bronchiolitis dashboard (August 2016) consolidating disparate data sources loaded within 2 to 4 days of discharge. In total, 35% of ED clinicians logged in. Leaders used the dashboard to target and track interventions such as a bronchodilator order alert. There were improvements in most outcome metrics; however, timing did not suggest direct dashboard impact. ED balancing measures were lower after implementation.

CONCLUSION

We described use of a dashboard to support a multifaceted QI initiative for bronchiolitis. Leaders used the dashboard for targeted interventions but the dashboard did not directly impact the observed improvements. Future studies should assess reasons for low individual dashboard use.
