Effectiveness of Targeted Interventions on Treatment of Infants With Bronchiolitis: A Randomized Clinical Trial

Review article: A primer for clinical researchers in the emergency department: Part XIII. Strategies to engage staff and enhance participant recruitment in emergency department research

Conducting research in ED is important and necessary to improve emergency care. Effective recruitment is an essential ingredient for the success of a research project and must be carefully monitored. Research coordinators are focused on optimising recruitment to research studies while also ensuring that the needs of participants and their families are met, and the research is acceptable to ED staff. In this paper, a group of experienced research coordinators from Australia and New Zealand have shared their strategies to engage staff and enhance recruitment of participants in emergency research. Although this paper is from a paediatric research network, the findings are applicable for EDs in general, both in Australasia and elsewhere.

Sustainability assessment of a quality improvement initiative on the management of bronchiolitis

BACKGROUND

A bronchiolitis integrated care pathway (BICP) achieved an 87% reduction in the use of medications in our regional health service (RHS) during the 2019-2020 season.

AIM

This study aimed to assess the sustainability of the changes in bronchiolitis management over 3 years after implementation of the BICP.

METHODS

A prospective observational study on rates of medications prescribing in children diagnosed with bronchiolitis in 135 primary care (PC) centres and eight hospital emergency departments (EDs) in the Basque Country, Spain, was conducted during the four bronchiolitis seasons between 2019 and 2023. Over this period, the deployment of BICP-related actions continued in our RHS. In addition, a strategy was designed to enhance the sustainability of the results. The main endpoint was the percentage of children prescribed salbutamol.

RESULTS

Over the 2019-2020 to 2022-2023 epidemic waves, 12 966 infants were diagnosed with bronchiolitis in PC, and 6676 infants in EDs. Rates of salbutamol use over the four waves were 5.04%, 10.54%, 8.51% and 6.05%, respectively, in PC and 3.36%, 10.02%, 7.62% and 5.77% in EDs. Rates of concomitant administration of other medications in EDs over the four waves were 3.2%, 0.2%, 1.0% and 1.9% for epinephrine and 0.4%, 0.7%, 0.3% and 0.4% for corticosteroids, respectively. In PC, prescribing rates were 5.1% and 1.8%, 10.3% and 4.1% for antibiotics and 7.8% and 4.5%, 5.7% and 2.5% for corticosteroids, respectively.

CONCLUSIONS

Reductions in the use of medications for bronchiolitis achieved in 2019 through the implementation of our integrated clinical pathway have been sustained over the three subsequent waves.

Appraisal of Australian and New Zealand paediatric sepsis guidelines

OBJECTIVE

Clinical practice guidelines (CPGs) are an important tool for the management of children with sepsis. The quality, consistency and concordance of Australian and New Zealand (ANZ) childhood sepsis CPGs with the Australian Commission on Safety and Quality in Healthcare (ACSQHC) sepsis clinical care standards and international sepsis guidelines is unclear.

METHODS

We accessed childhood sepsis CPGs for all ANZ states and territories through Paediatric Research in Emergency Departments International Collaborative members. The guidelines were assessed for quality using the AGREE-II instrument. Consistency between CPG treatment recommendations was assessed, as was concordance with the ACSQHC sepsis clinical care standards and international sepsis guidelines.

RESULTS

Overall, eight CPGs were identified and assessed. CPGs used a narrative and pathway format, with those using both having the highest quality overall. CPG quality was highest for description of scope and clarity of presentation, and lowest for editorial independence. Consistency between guidelines for initial treatment recommendations was poor, with substantial variation in the choice and urgency of empiric antimicrobial administration; the choice, volume and urgency of fluid resuscitation; and the choice of first-line vasoactive agent. Most CPGs were concordant with time-critical components of the ACSQHC sepsis clinical care standard, although few addressed post-acute care. Concordance with international sepsis guidelines was poor.

CONCLUSION

Childhood sepsis CPGs in current use in ANZ are of variable quality and lack consistency with key treatment recommendations. CPGs are concordant with the ACSQHC care standard, but not with international sepsis guidelines. A bi-national sepsis CPG may reduce unnecessary variation in care.

Understanding the uptake and adaption of targeted implementation interventions for reducing bronchiolitis investigations and therapies

AIM

To understand and evaluate the uptake and local adaptations of proven targeted implementation interventions that have effectively reduced unnecessary investigations and therapies in infants with bronchiolitis within emergency departments.

METHODS

A multi-centred, mixed-methods quality improvement study in four Australian hospitals that provide paediatric emergency and inpatient care from May to December 2021. All hospitals were provided with the same implementation intervention package and training. Real-time tracking logs of adaptions were completed followed by semi-structured interviews. Interviews were recorded, transcribed and subsequently coded using FRAME-IS to further describe the adaptions made.

RESULTS

Tracking logs were summarised and data from 12 interviews were compared from participating sites. The intervention resulted in 116 education sessions and a total of 23 adaptations made to educational materials, both content and contextual. Shortening education presentations, addition of bronchiolitis definitions, formatting of materials and novel interventions were the most common modifications. Audit and feedback were completed across all sites with varying utilisation. Targeted teaching was noted to dictate adaptions prior to and during implementation.

CONCLUSION

Quantitative and qualitative analysis of clinical 'real-world' adaptations to proven targeted implementation interventions allows invaluable insight for future de-implementation initiatives and national roll-out of implementation packages in the ED setting.

Reducing unwarranted chest x-rays in bronchiolitis: Importance of a robust analysis

AIM

Bronchiolitis is the commonest reason for hospitalisation amongst infants and is often a target for low-value care (LVC) reduction. We aimed to assess the impact of a multifaceted intervention (clinician education, parent engagement, audit-feedback) on rates of chest x-rays (CXR) in bronchiolitis.

METHODS

Longitudinal study of CXRs ordered in infants (1-12 months) diagnosed with bronchiolitis in the Emergency Department (ED) of an Australian paediatric hospital between May 2016 and February 2023. We used logistic regression to measure the impact of the intervention on unwarranted CXR orders, controlling for other potential impacting variables such as time, patient characteristics (age/sex), clinical variables (fever, hypoxia, tachypnoea), seasonal factors (month, day of the week, business hours) and time passed since intervention.

RESULTS

Ten thousand one hundred and nine infants were diagnosed with bronchiolitis in the ED over the study period, with 939 (9.3%) receiving a CXR, of which 69% (n = 651) were considered unwarranted. Rates of unwarranted CXRs reduced from 7.9% to 5.4% post-intervention (P < 0.0001). Logistic regression showed the intervention had no significant effect (OR 0.89, 95% CI 0.65-1.23) once other variables and underlying time-based trends were accounted for.

CONCLUSIONS

Although pre-post rates appeared significantly improved, a robust analysis demonstrated that our multi-faceted intervention was not effective in reducing CXRs in bronchiolitis. The decision to order CXR was associated with clinical features that overlap with pneumonia suggesting ongoing misconceptions regarding the role of CXR for this indication. Our study highlights the value of large electronic medical record datasets and robust methodology to avoid falsely attributing underlying trends to the LVC intervention.

Outcomes of medically retrieved infants with bronchiolitis in high-income countries: A scoping review

INTRODUCTION

Bronchiolitis is the most common respiratory infection and reason for hospitalisation in infancy; however, outcomes of infants with bronchiolitis who require interhospital transfer by specialist medical retrieval services are poorly understood.

OBJECTIVES

The objective of this study was to summarise current evidence of the rate, therapy, and outcomes of infants with bronchiolitis who required medical retrieval for ongoing management.

REVIEW METHOD

A scoping literature review informed by the Joanna Briggs Institute methodology was used including published studies in any language covering the period 1996 to December 2022 and grey literature sources comprised of reports from retrieval services in high-income countries with comparable healthcare systems.

DATA SOURCES

Medline, CINAHL, and the Cochrane Database of Systematic Reviews electronic databases were the sources for published studies. Grey literature sources were retrieval service web pages/social media sites from Australia, Canada, New Zealand, the United Kingdom, and the United States of America.

RESULTS

Searching identified 12 677 records, with 12 069 ineligible records and 286 duplicates excluded at screening. Of the 72 papers included for title and abstract review, 16 were selected for full-text review. Six papers fulfilled inclusion criteria. Infants with bronchiolitis were the primary focus of three studies. Transfer rate was reported in four studies, ranging from 4.3% to 18.5%. Use of respiratory therapy was variably reported and was associated with prematurity. Outcomes following retrieval such as respiratory therapies, days on therapies, length of stay in the intensive care unit, and hospital length of stay were only reported in two studies. Of 103 identified medical retrieval services and data registries, no reports were found that included information on the number of transfers or outcomes for infants with bronchiolitis.

CONCLUSIONS

Up to one in five infants with bronchiolitis require medical retrieval. Only two published studies and no reports reported on the number and outcomes of infants. Given the frequency and severity of bronchiolitis, understanding indications for medical retrieval and outcomes of those infants may help to better target care and interventions for this common illness. Benefits could include diminishing the costly burden to families and the healthcare system of avoidable medical retrieval and interhospital transfer.

Parent and Clinician Views on Not Using Antibiotics for Mild Community-Acquired Pneumonia

OBJECTIVES

Preschool-aged children with mild community-acquired pneumonia (CAP) routinely receive antibiotics even though most infections are viral. We sought to identify barriers to the implementation of a "no antibiotic" strategy for mild CAP in young children.

METHODS

Qualitative study using semistructured interviews conducted in a large pediatric hospital in the United States from January 2021 to July 2021. Parents of young children diagnosed with mild CAP in the previous 3 years and clinicians practicing in outpatient settings (pediatric emergency department, community emergency department, general pediatrics offices) were included.

RESULTS

Interviews were conducted with 38 respondents (18 parents, 20 clinicians). No parent heard of the no antibiotic strategy, and parents varied in their support for the approach. Degree of support related to their desire to avoid unnecessary medications, trust in clinicians, the emotional difficulty of caring for a sick child, desire for relief of suffering, willingness to accept the risk of unnecessary antibiotics, and judgment about the child's illness severity. Eleven (55%) clinicians were familiar with guidelines specifying a no antibiotic strategy. They identified challenges in not using antibiotics, including diagnostic uncertainty, consequences of undertreatment, parental expectations, follow-up concerns, and acceptance of the risks of unnecessary antibiotic treatment of many children if it means avoiding adverse outcomes for some children.

CONCLUSIONS

Although both parents and clinicians expressed broad support for the judicious use of antibiotics, pneumonia presents stewardship challenges. Interventions will need to consider the emotional, social, and logistical aspects of managing pneumonia, in addition to developing techniques to improve diagnosis.

What works for and what hinders deimplementation of low-value care in emergency medicine practice? A scoping review

OBJECTIVES

Low-value care can harm patients and healthcare systems. Despite a decade of global endeavours, low value care has persisted. Identification of barriers and enablers is essential for effective deimplementation of low-value care. This scoping review is an evidence summary of barriers, enablers and features of effective interventions for deimplementation of low-value care in emergency medicine practice worldwide.

DESIGN

A mixed-methods scoping review was conducted using the Arksey and O'Malley framework.

DATA SOURCES

Medline, CINAHL, Embase, EMCare, Scopus and grey literature were searched from inception to 5 December 2022.

ELIGIBILITY CRITERIA

Primary studies which employed qualitative, quantitative or mixed-methods approaches to explore deimplementation of low-value care in an EM setting and reported barriers, enablers or interventions were included. Reviews, protocols, perspectives, comments, opinions, editorials, letters to editors, news articles, books, chapters, policies, guidelines and animal studies were excluded. No language limits were applied.

DATA EXTRACTION AND SYNTHESIS

Study selection, data collection and quality assessment were performed by two independent reviewers. Barriers, enablers and interventions were mapped to the domains of the Theoretical Domains Framework. The Mixed Methods Appraisal Tool was used for quality assessment.

RESULTS

The search yielded 167 studies. A majority were quantitative studies (90%, 150/167) that evaluated interventions (86%, 143/167). Limited provider abilities, diagnostic uncertainty, lack of provider insight, time constraints, fear of litigation, and patient expectations were the key barriers. Enablers included leadership commitment, provider engagement, provider training, performance feedback to providers and shared decision-making with patients. Interventions included one or more of the following facets: education, stakeholder engagement, audit and feedback, clinical decision support, nudge, clinical champions and training. Multifaceted interventions were more likely to be effective than single-faceted interventions. Effectiveness of multifaceted interventions was influenced by fidelity of the intervention facets. Use of behavioural change theories such as the Theoretical Domains Framework in the published studies appeared to enhance the effectiveness of interventions to deimplement low-value care.

CONCLUSION

High-fidelity, multifaceted interventions that incorporated education, stakeholder engagement, audit/feedback and clinical decision support, were administered daily and lasted longer than 1 year were most effective in achieving deimplementation of low-value care in emergency departments. This review contributes the best available evidence to date, but further rigorous, theory-informed, qualitative and mixed-methods studies are needed to supplement the growing body of evidence to effectively deimplement low-value care in emergency medicine practice.

Evaluation of Severe Acute Respiratory Syndrome surveillance caused by respiratory viruses in a pediatric unit, 2013 to 2019

OBJECTIVE

To evaluate severe acute respiratory syndrome surveillance in a pediatric unit.

METHODS

Descriptive study of reported severe acute respiratory syndrome cases with the detection of respiratory viruses in the nasopharyngeal sample of patients hospitalized between 2013 and 2019, in a reference hospital in the Federal District, Brazil.

RESULTS

A total of 269 children had one or more viruses detected, resulting in 280 viruses, of which 152 (54%) were respiratory syncytial virus. The detection of respiratory syncytial virus was higher during the autumn-winter period. Children´s median age was 6.9 months, 156 (58%) were male, 104 (39%) had comorbidity, 197 (73%) required mechanical ventilation, 241 (90%) received antibiotics, and 146 (54%) oseltamivir. There were 19 (7%) deaths. The median time from symptom onset to sample collection was 5 days and the median time from sample collection to final results was 6 days.

CONCLUSIONS

The system needs to reduce the time to deliver results so that inappropriate use of antibiotics and antivirals can be avoided. Moreover, the burden of viral pneumonia was relevant and the system must be flexible enough to include emerging viruses in order to be useful in responding to public health emergencies caused by respiratory viruses.

Qualitative study of emergency clinicians to inform a national guideline on the management of children with mild-to-moderate head injuries

BACKGROUND

Head injury is a common reason children present to EDs. Guideline development to improve care for paediatric head injuries should target the information needs of ED clinicians and factors influencing its uptake.

METHODS

We conducted semi-structured qualitative interviews (November 2017-November 2018) with a stratified purposive sample of ED clinicians from across Australia and New Zealand. We identified clinician information needs, used the Theoretical Domains Framework (TDF) to explore factors influencing the use of head CT and clinical decision rules/guidelines in CT decision-making, and explored ways to improve guideline uptake. Two researchers coded the interview transcripts using thematic content analysis.

RESULTS

A total of 43 clinicians (28 doctors, 15 nurses), from 19 hospitals (5 tertiary, 8 suburban, 6 regional/rural) were interviewed. Clinicians sought guidance for scenarios including ED management of infants, children with underlying medical issues, delayed or representations and potential non-accidental injuries. Improvements to the quality and content of discharge communication and parental discussion materials were suggested. Known risks of radiation from head CTs has led to a culture of observation over use of CT in Australasia (TDF domain: beliefs about consequences). Formal and informal policies have resulted in senior clinicians making most head CT decisions in children (TDF domain: behavioural regulation). Senior clinicians consider their gestalt to be more accurate and outperform existing guidance (TDF domain: beliefs about capabilities), although they perceive guidelines as useful for training and supporting junior staff. Summaries, flow charts, publication in ED-specific journals and scripted training materials were suggestions to improve uptake.

CONCLUSION

Information needs of ED clinicians, factors influencing use of head CT in children with head injuries and the role of guidelines were identified. These findings informed the scope and implementation strategies for an Australasian guideline for mild-to-moderate head injuries in children.

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.

International variation in evidence-based emergency department management of bronchiolitis: a retrospective cohort study

OBJECTIVES

We aimed to evaluate the international variation in the use of evidence-based management (EBM) in bronchiolitis. We hypothesised that management consistent with full-EBM practices is associated with the research network of care, adjusted for patient-level characteristics. Secondary objectives were to determine the association between full-EBM and (1) hospitalisation and (2) emergency department (ED) revisits resulting in hospitalisation within 21 days.

DESIGN

A secondary analysis of a retrospective cohort study.

SETTING

38 paediatric EDs belonging to the Paediatric Emergency Research Network in Canada, USA, Australia/New Zealand UK/Ireland and Spain/Portugal.

PATIENTS

Otherwise healthy infants 2-11 months old diagnosed with bronchiolitis between 1 January 2013 and 31 December, 2013.

OUTCOME MEASURES

Primary outcome was management consistent with full-EBM, that is, no bronchodilators/corticosteroids/antibiotics, no chest radiography or laboratory testing. Secondary outcomes included hospitalisations during the index and subsequent ED visits.

RESULTS

1137/2356 (48.3%) infants received full-EBM (ranging from 13.2% in Spain/Portugal to 72.3% in UK/Ireland). Compared with the UK/Ireland, the adjusted ORs (aOR) of full-EBM receipt were lower in Spain/Portugal (aOR 0.08, 95% CI 0.02 to 0.29), Canada (aOR 0.13 (95% CI 0.06 to 0.31) and USA (aOR 0.16 (95% CI 0.07 to 0.35). EBM was less likely in infants with dehydration (aOR 0.49 (95% CI 0.33 to 0.71)), chest retractions (aOR 0.69 (95% CI 0.52 to 0.91)) and nasal flaring (aOR 0.69 (95% CI 0.52 to 0.92)). EBM was associated with reduced odds of hospitalisation at the index visit (aOR 0.77 (95% CI 0.60 to 0.98)) but not at revisits (aOR 1.17 (95% CI 0.74 to 1.85)).

CONCLUSIONS

Infants with bronchiolitis frequently do not receive full-EBM ED management, particularly those outside of the UK/Ireland. Furthermore, there is marked variation in full-EBM between paediatric emergency networks, and full-EBM delivery is associated with lower likelihood of hospitalisation. Given the global bronchiolitis burden, international ED-focused deimplementation of non-indicated interventions to enhance EBM is needed.

Is slide-based or video-based eLearning better at achieving behavioural change in bronchiolitis management? A cluster-based randomised control trial

AIM

This cluster-based randomised control trial examines the comparative efficacy of two eLearning programs that teach clinicians evidence-based bronchiolitis management for children less than 12 months of age.

METHODS

Six hospitals, matched for size, were randomly allocated to either video-based (arm A) or slide-based (arm B) eLearning programs. To assess behavioural change, participants (doctors and nurses) were asked to declare how they would manage a video scenario of an infant with bronchiolitis, before and after either eLearning method. Measured outcomes included the number of investigations and treatments ordered, admissions to hospital and discharge planning. Confidence scores and change in understanding for bronchiolitis management were also measured.

RESULTS

Both methods of eLearning instruction resulted in reductions in unnecessary investigations and treatments performed, as well as improved confidence and understanding of bronchiolitis management on the video scenario. Video-based eLearning instruction additionally demonstrated a significant reduction in unnecessary hospital admissions and better discharge planning, based on learners' declarations to the video scenario, relative to slide-based learning.

CONCLUSION

Slide-based and video-based eLearning both demonstrate improvements in reported bronchiolitis management. However, video-based eLearning may yield more significant practice changes, improved clinician confidence in management, as well as improved patient experience.

Prevalence of high flow nasal cannula therapy use for management of infants with bronchiolitis in Australia and New Zealand

AIM

To determine the prevalence of high flow nasal cannula (HFNC) therapy in infants presenting to hospital in Australia and New Zealand with bronchiolitis over four bronchiolitis seasons. Secondary aims were to determine temporal trends in HFNC use, and associations between HFNC, hospital length of stay (LOS) and intensive care unit (ICU) admission.

METHODS

A planned sub-study of a multi-centre international cluster randomised controlled trial investigating knowledge translation strategies for a bi-national bronchiolitis guideline. Demographics, management and outcomes data were collected retrospectively for infants presenting with bronchiolitis to 26 hospitals between 1 May 2014 and 30 November 2017. Prevalence data are presented as absolute frequencies (95% confidence interval (CI)) with differences between groups for continuous and categorical variables analysed using linear and logistic regression, respectively.

RESULTS

11 715 infants were included with 3392 (29.0%, 95% CI (28.1-29.8%)) receiving oxygen therapy; of whom 1817 (53.6%, 95% CI (51.9-55.3%)) received HFNC. Use of oxygen therapy did not change over the four bronchiolitis seasons (P = 0.12), while the proportion receiving HFNC increased (2014, 336/2587 (43.2%); 2017, 609/3720 (57.8%); P ≤ 0.001). Infants who received HFNC therapy were not substantially different to infants who received oxygen therapy without HFNC. HFNC use was associated with increases in both hospital LOS (P < 0.001) and ICU admissions (P < 0.001).

CONCLUSION

Use of HFNC therapy for infants with bronchiolitis increased over 4 years. Of those who received oxygen therapy, the majority received HFNC therapy without improvement in hospital LOS or ICU admissions. Strategies to guide appropriate HFNC use in infants with bronchiolitis are required.

Review article: A primer for clinical researchers in the emergency department: Part XII. Sustainability of improvements in care: An introduction

Despite an increased focus on ways to improve implementation of evidence and de-implementation of practices with no known benefit, there is limited guidance on how to sustain these improvements. This review provides an introduction to sustainability of improvements in care and sustainability research, discussing how to support sustainability in practice and detailing a sustainability research agenda for the emergency medicine setting.

Use of the Theoretical Domains Framework to explore factors influencing paediatric fever management practices and antipyretic use in New Zealand emergency departments

AIM

To explore factors influencing fever management practices and antipyretic use among New Zealand Emergency Department (ED) doctors and nurses using the Theoretical Domains Framework (TDF).

METHODS

Cross-sectional survey of doctors and nurses across 11 New Zealand EDs. The questionnaire examined eight of 12 TDF domains, based on a generic questionnaire validated to assess TDF-based determinants of health-care professional behaviour. Relevant domains were identified by the frequency of beliefs; the presence of conflicting beliefs within a domain; and the likely strength of impact of a belief on paediatric fever management in the ED.

RESULTS

About 602 participants (243 doctors, 353 nurses and 6 unknown) completed the survey (response rate 47.5%). Over half (351/591, 59.6%, 95% confidence interval (CI) 55.5-63.5%) knew the content of clinical practice guidelines regarding antipyretic use in febrile children (TDF Domain Knowledge), or had been trained to ensure antipyretics are given to febrile children only if they appear distressed (347/592, 58.6%, 95% CI 54.5-62.6%) (Skills). Over 40% (246/590, 95% CI 37.7-45.8%) aim to reduce the fever before discharge (Goals). Most (444/591, 75.1%, 95% CI 71.4-78.6%) participants felt capable of explaining appropriate antipyretic use to parents/care givers (Beliefs about Capabilities). Only a minority (155/584, 26.5%, 95% CI 23.0-30.3%) thought that they can ensure antipyretics are given to febrile children only if they appear distressed when the ED is busy (Environmental Context and Resources).

CONCLUSIONS

Using the TDF, we identified factors influencing fever management practices and antipyretic use in the ED. These factors can guide the design of targeted, theory-informed knowledge translation strategies.

Sustainability of evidence-based practices in the management of infants with bronchiolitis in hospital settings - a PREDICT study protocol

Background

Understanding how and why de-implementation of low-value practices is sustained remains unclear. The Paediatric Research in Emergency Departments International CollaboraTive (PREDICT) Bronchiolitis Knowledge Translation (KT) Study was a cluster randomised controlled trial conducted in 26 Australian and New Zealand hospitals (May-November 2017). Results showed targeted, theory-informed interventions (clinical leads, stakeholder meetings, train-the-trainer workshop, targeted educational package, audit/feedback) were effective at reducing use of five low-value practices for bronchiolitis (salbutamol, glucocorticoids, antibiotics, adrenaline and chest x-ray) by 14.1% in acute care settings. The primary aim of this study is to determine the sustainability (continued receipt of benefits) of these outcomes at intervention hospitals two-years after the removal of study supports. Secondary aims are to determine sustainability at one-year after removal of study support at intervention hospitals; improvements one-and-two years at control hospitals; and explore factors that influence sustainability at intervention hospitals and contribute to improvements at control hospitals.

Methods

A mixed-methods study design. The quantitative component is a retrospective medical record audit of bronchiolitis management within 24 hours of emergency department (ED) presentations at 26 Australian (n = 20) and New Zealand (n = 6) hospitals, which participated in the PREDICT Bronchiolitis KT Study. Data for a total of 1800 infants from intervention and control sites (up to 150 per site) will be collected to determine if improvements (i.e., no use of all five low-value practices) were sustained two- years (2019) post-trial (primary outcome; composite score); and a further 1800 infants from intervention and control sites will be collected to determine sustained improvements one- year (2018) post-trial (secondary outcome). An a priori definition of sustainability will be used. The qualitative component will consist of semi-structured interviews with three to five key emergency department and paediatric inpatient medical and nursing staff per site (total n = 78-130). Factors that may have contributed to sustaining outcomes and/or interventions will be explored and mapped to an established sustainability framework.

Discussion

This study will improve our understanding of the sustainability of evidence-based bronchiolitis management in infants. Results will also advance implementation science research by informing future de-implementation strategies to reduce low-value practices and sustain practice change in paediatric acute care.

Bronchiolitis

Viral bronchiolitis is the most common cause of admission to hospital for infants in high-income countries. Respiratory syncytial virus accounts for 60-80% of bronchiolitis presentations. Bronchiolitis is diagnosed clinically without the need for viral testing. Management recommendations, based predominantly on high-quality evidence, advise clinicians to support hydration and oxygenation only. Evidence suggests no benefit with use of glucocorticoids or bronchodilators, with further evidence required to support use of hypertonic saline in bronchiolitis. Evidence is scarce in the intensive care unit. Evidence suggests use of high-flow therapy in bronchiolitis is limited to rescue therapy after failure of standard subnasal oxygen only in infants who are hypoxic and does not decrease rates of intensive care unit admission or intubation. Despite systematic reviews and international clinical practice guidelines promoting supportive rather than interventional therapy, universal de-implementation of interventional care in bronchiolitis has not occurred and remains a major challenge.

Local healthcare professionals need to work together to implement bronchiolitis guidelines that stop unnecessary tests and treatments

AIM

This mini review summarised studies published over a 10-year period on the impact of guidelines for diagnosing and managing bronchiolitis in children, with a special focus on interventions that enhanced adherence during implementation.

METHODS

PubMed was searched from 1 December 2011 to 31 November 2021 for papers published in English that used the terms bronchiolitis, child or infant, guidelines and either implementation or impact. After the exclusion criteria had been applied, 27 articles were reviewed in more detail. Eight described protocols without any comparisons and were excluded. Ten of the 19 remaining studies evaluated the impact of bronchiolitis guidelines, and 9 examined the effects of interventions linked to their publication.

RESULTS

Just releasing evidence-based guidelines had a poor impact, but this improved when local tailored current care, clinical practice or best-practice guidelines were issued. Even better results were achieved when all the staff treating bronchiolitis patients participated in the preparation and implementation of local guidelines. Adherence to the guidelines was as high as 85% when multidisciplinary, and multifaceted interventions were used to complement the publication of guidelines.

CONCLUSION

Healthcare professionals need to work together to avoid children receiving bronchiolitis management that is unnecessary and not based on evidence.

Can targeted interventions change the factors influencing variation in management of infants with bronchiolitis? A survey of Australian and New Zealand clinicians: A paediatric research in emergency departments international collaborative (PREDICT) study

AIM

This study aimed to determine whether targeted interventions, proven to be effective at improving evidence-based bronchiolitis management, changed factors previously found to influence variation in bronchiolitis management.

METHODS

This survey assessed change in factors influencing clinicians' (nurses and doctors) bronchiolitis management at baseline and post-intervention in a cluster randomised controlled trial of targeted, theory-informed interventions aiming to de-implement non-evidence-based bronchiolitis management (no use of chest X-ray, salbutamol, antibiotics, glucocorticoids and adrenaline). Survey questions addressed previously identified factors influencing bronchiolitis management from six Theoretical Domains Framework domains (knowledge; skills; beliefs about consequences; social/professional role and identity; environmental context and resources; social influences). Data analysis was descriptive.

RESULTS

A total of 1958 surveys (baseline = 996; post-intervention = 962) were completed by clinicians from the emergency department and paediatric inpatient units from 26 hospitals (intervention = 13; control = 13). Targeted bronchiolitis interventions significantly increased knowledge of the Australasian Bronchiolitis Guideline (intervention clinicians = 74%, control = 39%, difference = 34.7%, 95% confidence interval (CI) = 25.6-43.8%), improved skills in diagnosing (intervention doctors = 89%, control = 76%, difference = 12.6%, 95% CI = 6.2-19%) and managing bronchiolitis (intervention doctors = 87%, control = 76%, difference = 9.9%, 95% CI = 3.7-16.1%), positively influenced both beliefs about consequences regarding salbutamol use (intervention clinicians = 49%, control = 29%, difference = 20.3%, 95% CI = 13.2-27.4%) and nurses questioning non-evidence-based bronchiolitis management (chest X-ray: intervention = 71%, control = 51%, difference = 20.8%, 95% CI = 11.4-30.2%; glucocorticoids: intervention = 64%, control = 40%, difference = 21.9%, 95% CI = 10.4-33.5%) (social/professional role and identity). A 14% improvement in evidence-based bronchiolitis management favouring intervention hospitals was demonstrated in the cluster randomised controlled trial.

CONCLUSION

Targeted interventions positively changed factors influencing bronchiolitis management resulting in improved evidence-based bronchiolitis care. This study has important implications for improving bronchiolitis management and future development of interventions to de-implement low-value care.

Using theories and frameworks to understand how to reduce low-value healthcare: a scoping review

BACKGROUND

There is recognition that the overuse of procedures, testing, and medications constitutes low-value care which strains the healthcare system and, in some circumstances, can cause unnecessary stress and harm for patients. Initiatives across dozens of countries have raised awareness about the harms of low-value care but have had mixed success and the levels of reductions realized have been modest. Similar to the complex drivers of implementation processes, there is a limited understanding of the individual and social behavioral aspects of de-implementation. While researchers have begun to use theory to elucidate the dynamics of de-implementation, the research remains largely atheoretical. The use of theory supports the understanding of how and why interventions succeed or fail and what key factors predict success. The purpose of this scoping review was to identify and characterize the use of theoretical approaches used to understand and/or explain what influences efforts to reduce low-value care.

METHODS

We conducted a review of MEDLINE, EMBASE, CINAHL, and Scopus databases from inception to June 2021. Building on previous research, 43 key terms were used to search the literature. The database searches identified 1998 unique articles for which titles and abstracts were screened for inclusion; 232 items were selected for full-text review.

RESULTS

Forty-eight studies met the inclusion criteria. Over half of the included articles were published in the last 2 years. The Theoretical Domains Framework (TDF) was the most commonly used determinant framework (n = 22). Of studies that used classic theories, the majority used the Theory of Planned Behavior (n = 6). For implementation theories, Normalization Process Theory and COM-B were used (n = 7). Theories or frameworks were used primarily to identify determinants (n = 37) and inform data analysis (n = 31). Eleven types of low-value care were examined in the included studies, with prescribing practices (e.g., overuse, polypharmacy, and appropriate prescribing) targeted most frequently.

CONCLUSIONS

This scoping review provides a rigorous, comprehensive, and extensive synthesis of theoretical approaches used to understand and/or explain what factors influence efforts to reduce low-value care. The results of this review can provide direction and insight for future primary research to support de-implementation and the reduction of low-value care.

Cough and cold medicine prescription rates can be significantly reduced by active intervention

Our aim was to construct and test an intervention programme to eradicate cough and cold medicine (CCM) prescriptions for children treated in a nationwide healthcare service company. The study was carried out in the largest private healthcare service company in Finland with a centralised electronic health record system allowing for real-time, doctor-specific practice monitoring. The step-by-step intervention consisted of company-level dissemination of educational materials to doctors and families, educational staff meetings, continuous monitoring of prescriptions, and targeted feedback. Outreach visits were held in noncompliant units. Finally, those physicians who most often prescribed CCM were directly contacted. During the intervention period (2017-2020), there were more than one million paediatric visits. Prescriptions of CCMs to children were completely eradicated in 41% of units and the total number of CCM prescriptions decreased from 6738 to 744 (89%). During the fourth intervention year, CCMs containing opioid derivatives were prescribed for only 0.2% of children aged < 2 years. The decrease in prescriptions was greatest in general practitioners (5.2 to 1.1%). In paediatricians, the prescription rates decreased from 1.5 to 0.2%. The annual costs of CCMs decreased from €183,996 to €18,899 (89.7%). For the intervention, the developers used 343 h and the attended doctors used 684 h of work time during the 4-year intervention. The costs used for developing, implementing, reporting, evaluating, communicating, and data managing formed approximately 11% of total intervention costs.

CONCLUSION

The study showed that a nationwide systematic intervention to change cough medicine prescription practices is feasible and requires only modest financial investments.

WHAT IS KNOWN

• Cough and cold medicines (CCM) are not effective or safe, especially for children aged 6 years. • Although the use of CCMs has been declining, caregivers continue to administer CCMs to children, and some physicians still prescribe them even for preschool children.

WHAT IS NEW

• A nationwide systematic intervention can significantly and cost effectively change CCM prescription habits of paediatricians, general practitioners, and other specialists. • Electronic health records provide additional tools for operative guideline implementation and real-time quality monitoring, including recommendations of useless or harmful treatments.

Current treatment practice of functional abdominal pain disorders in children: A multicenter survey

BACKGROUND

Approximately 90% of the children with chronic abdominal pain are diagnosed as having functional abdominal pain disorder (FAPD). The Dutch guideline "functional abdominal pain" provides a stepwise approach to treat FAPD. The aim of this survey was twofold first, to determine adherence to the Dutch guideline, and second to determine current management of FAPDs in clinical practice.

METHODS

A multicenter survey was designed. The survey was sent to pediatricians and pediatric residents in December 2020. The study ran from October 2020 until March 2021. Participants in ten hospitals in the western region of The Netherlands were invited to complete this survey. Respondents who indicated not to treat children with FAPDs or respondents who completed less than 3 steps of the survey were excluded.

RESULTS

In total, 85/174 (48.9%) respondents completed the survey. We included 80 respondents, 68 pediatricians and 12 pediatric residents, for analysis. Overall, self-reported guideline adherence was 85%. Self-reported adherence was higher than actual adherence. Only 50% of all respondents followed the first three steps of the guideline. The reported non-pharmacological and pharmacological treatments were diverse and varied between different age groups. The average follow-up duration was between 2 and 6 months, and the most regularly used outcome measures were attendance at school, quality of life, and adequate pain relief/reassurance.

CONCLUSION

We reportedly observed a large variation in the management of children with FAPDs, due to low guideline adherence among clinicians. Improved guideline adherence may be accomplished by updating the guideline with specific recommendations per subtype, follow-up and outcome measures as well measures to improve guideline implementation.

COVID-19 Lesson for Respiratory Syncytial Virus (RSV): Hygiene Works

Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory tract infections (LRTIs) in infants worldwide. The global direct medical cost associated with RSV LRTIs reaches billions of dollars, with the highest burden in low–middle-income countries. Many efforts have been devoted to improving its prevention and management, including both non-pharmaceutical and pharmaceutical strategies, often with limited routine use in high-income countries due to high costs. During the ongoing COVID-19 pandemic, a dramatic decrease in RSV infections (up to 70–90%) has been reported around the globe, directly related to the implementation of containment measures (face masks, hand hygiene, and social distancing). Primary prevention has demonstrated the highest cost effectiveness ratio in reducing the burden of a respiratory infection such as RSV, never reached before. Thus, we emphasize the importance of non-pharmaceutical preventive hygiene measures that should be implemented and maintained even after the COVID-19 outbreak.

Process evaluation of a cluster randomised controlled trial to improve bronchiolitis management - a PREDICT mixed-methods study

BACKGROUND

Bronchiolitis is the most common reason for hospitalisation in infants. All international bronchiolitis guidelines recommend supportive care, yet considerable variation in practice continues with infants receiving non-evidence based therapies. We developed six targeted, theory-informed interventions; clinical leads, stakeholder meeting, train-the-trainer, education delivery, other educational materials, and audit and feedback. A cluster randomised controlled trial (cRCT) found the interventions to be effective in reducing use of five non-evidence based therapies in infants with bronchiolitis. This process evaluation paper aims to determine whether the interventions were implemented as planned (fidelity), explore end-users' perceptions of the interventions and evaluate cRCT outcome data with intervention fidelity data.

METHODS

A pre-specified mixed-methods process evaluation was conducted alongside the cRCT, guided by frameworks for process evaluation of cRCTs and complex interventions. Quantitative data on the fidelity, dose and reach of interventions were collected from the 13 intervention hospitals during the study and analysed using descriptive statistics. Qualitative data identifying perception and acceptability of interventions were collected from 42 intervention hospital clinical leads on study completion and analysed using thematic analysis.

RESULTS

The cRCT found targeted, theory-informed interventions improved bronchiolitis management by 14.1%. The process evaluation data found variability in how the intervention was delivered at the cluster and individual level. Total fidelity scores ranged from 55 to 98% across intervention hospitals (mean = 78%; SD = 13%). Fidelity scores were highest for use of clinical leads (mean = 98%; SD = 7%), and lowest for use of other educational materials (mean = 65%; SD = 19%) and audit and feedback (mean = 65%; SD = 20%). Clinical leads reflected positively about the interventions, with time constraints being the greatest barrier to their use.

CONCLUSION

Our targeted, theory-informed interventions were delivered with moderate fidelity, and were well received by clinical leads. Despite clinical leads experiencing challenges of time constraints, the level of fidelity had a positive effect on successfully de-implementing non-evidence-based care in infants with bronchiolitis. These findings will inform widespread rollout of our bronchiolitis interventions, and guide future practice change in acute care settings.

Targeted Interventions Improve Bronchiolitis Management in Infants

According to this study: Targeted interventions improved the treatment of infants with bronchiolitis by reducing the use of non-evidence-based therapies without any identified negative consequences.

Development of targeted, theory-informed interventions to improve bronchiolitis management

BACKGROUND

Despite international guidelines providing evidence-based recommendations on appropriate management of infants with bronchiolitis, wide variation in practice occurs. This results in infants receiving care of no benefit, with associated cost and is potentially harmful. Theoretical frameworks are increasingly used to develop interventions, utilising behaviour change techniques specifically chosen to target factors contributing to practice variation, with de-implementation often viewed as harder than implementing. This paper describes the stepped process using the Theoretical Domains Framework (TDF) to develop targeted, theory-informed interventions which subsequently successfully improved management of infants with bronchiolitis by de-implementing ineffective therapies. Explicit description of the process and rationale used in developing de-implementation interventions is critical to dissemination of these practices into real world clinical practice.

METHODS

A stepped approach was used: (1) Identify evidence-based recommendations and practice variation as targets for change, (2) Identify factors influencing practice change (barriers and enablers) to be addressed, and (3) Identification and development of interventions (behaviour change techniques and methods of delivery) addressing influencing factors, considering evidence of effectiveness, feasibility, local relevance and acceptability. The mode of delivery for the intervention components was informed by evidence from implementation science systematic reviews, and setting specific feasibility and practicality.

RESULTS

Five robust evidence-based management recommendations, targeting the main variation in bronchiolitis management were identified: namely, no use of chest x-ray, salbutamol, glucocorticoids, antibiotics, and adrenaline. Interventions developed to target recommendations addressed seven TDF domains (identified following qualitative clinician interviews (n = 20)) with 23 behaviour change techniques chosen to address these domains. Final interventions included: (1) Local stakeholder meetings, (2) Identification of medical and nursing clinical leads, (3) Train-the-trainer workshop for all clinical leads, (4) Local educational materials for delivery by clinical leads, (5) Provision of tools and materials targeting influencing factors, and prompting recommended behaviours, and (6) Audit and feedback.

CONCLUSION

A stepped approach based on theory, evidence and issues of feasibility, local relevance and acceptability, was successfully used to develop interventions to improve management of infants with bronchiolitis. The rationale and content of interventions has been explicitly described allowing others to de-implement unnecessary bronchiolitis management, thereby improving care.

The Pediatric Emergency Research Network (PERN): A decade of global research cooperation in paediatric emergency care

OBJECTIVES

The Pediatric Emergency Research Network (PERN) was launched in 2009 with the intent for existing national and regional research networks in paediatric emergency care to organise globally for the conduct of collaborative research across networks.

METHODS

PERN has grown from five to eight member networks over the past decade. With an executive committee comprising representatives from all member networks, PERN plays a supportive and collaborative rather than governing role. The full impact of PERN's facilitation of international collaborative research, although somewhat difficult to quantify empirically, can be measured indirectly by the observed growth of the field, the nature of the increasingly challenging research questions now being addressed and the collective capacity to generate and implement new knowledge in treating acutely ill and injured children.

RESULTS

Beginning as a pandemic response studying H1N1 influenza risk factors in children, PERN research has progressed to multiple observational studies and ongoing global randomised controlled trials (RCTs). As a recent example, PERN has developed sufficient network infrastructure to enable the rapid initiation of a prospective observational study in response to the current COVID-19 pandemic.

CONCLUSIONS

Following its success with developing global research, the PERN goal now is to promote the implementation of scientific advances into everyday clinical practice by: (i) expanding the capacity for global RCTs; (ii) deepening the focus on implementation science; (iii) increasing attention to healthcare disparities; and (iv) expanding PERN's reach into resource-restricted regions. Through these actions, PERN aims to meet the needs of acutely ill and injured children throughout the world.

The Pediatric Emergency Research Network: A Decade of Global Research Cooperation in Pediatric Emergency Care

OBJECTIVES

The Pediatric Emergency Research Network (PERN) was launched in 2009 with the intent for existing national and regional research networks in pediatric emergency care to organize globally for the conduct of collaborative research across networks.

METHODS

The Pediatric Emergency Research Network has grown from 5- to 8-member networks over the past decade. With an executive committee comprising representatives from all member networks, PERN plays a supportive and collaborative rather than governing role. The full impact of PERN's facilitation of international collaborative research, although somewhat difficult to quantify empirically, can be measured indirectly by the observed growth of the field, the nature of the increasingly challenging research questions now being addressed, and the collective capacity to generate and implement new knowledge in treating acutely ill and injured children.

RESULTS

Beginning as a pandemic response with a high-quality retrospective case-controlled study of H1N1 influenza risk factors, PERN research has progressed to multiple observational studies and ongoing global randomized controlled trials. As a recent example, PERN has developed sufficient network infrastructure to enable the rapid initiation of a prospective observational study in response to the current coronavirus disease 2019 pandemic. In light of the ongoing need for translation of research knowledge into equitable clinical practice and to promote health equity, PERN is committed to a coordinated international effort to increase the uptake of evidence-based management of common and treatable acute conditions in all emergency department settings.

CONCLUSIONS

The Pediatric Emergency Research Network's successes with global research, measured by prospective observational and interventional studies, mean that the network can now move to improve its ability to promote the implementation of scientific advances into everyday clinical practice. Achieving this goal will involve focus in 4 areas: (1) expanding the capacity for global randomized controlled trials; (2) deepening the focus on implementation science; (3) increasing attention to healthcare disparities and their origins, with growing momentum toward equity; and (4) expanding PERN's global reach through addition of sites and networks from resource-restricted regions. Through these actions, PERN will be able to build on successes to face the challenges ahead and meet the needs of acutely ill and injured children throughout the world.
