    IMPORTANCE: In developed countries, bronchiolitis is the most common reason for infants to be admitted to the hospital, and all international bronchiolitis guidelines recommend supportive care; however, significant variation in practice continues with infants receiving non-evidence-based therapies. Deimplementation research aims to reduce the use of low-value care, and advancing science in this area is critical to delivering evidence-based care. OBJECTIVE: To determine the effectiveness of targeted interventions vs passive dissemination of an evidence-based bronchiolitis guideline in improving treatment of infants with bronchiolitis. DESIGN, SETTING, AND PARTICIPANTS: This international, multicenter cluster randomized clinical trial included 26 hospitals (clusters) in Australia and New Zealand providing tertiary or secondary pediatric care (13 randomized to intervention, 13 to control) during the 2017 bronchiolitis season. Data were collected on 8003 infants for the 3 bronchiolitis seasons (2014-2016) before the implementation period and 3727 infants for the implementation period (2017 bronchiolitis season, May 1-November 30). Data were analyzed from November 16, 2018, to December 9, 2020. INTERVENTIONS: Interventions were developed using theories of behavior change to target key factors that influence bronchiolitis management. These interventions included site-based clinical leads, stakeholder meetings, a train-the-trainer workshop, targeted educational delivery, other educational and promotional materials, and audit and feedback. MAIN OUTCOMES AND MEASURES: The primary outcome was compliance during the first 24 hours of care with no use of chest radiography, albuterol, glucocorticoids, antibiotics, and epinephrine, measured retrospectively from medical records of randomly selected infants with bronchiolitis who presented to the hospital. There were no patient-level exclusions. RESULTS: A total of 26 hospitals were randomized without dropouts. Analysis was by intention to treat. Baseline data collected on 8003 infants for 3 bronchiolitis seasons (2014-2016) before the implementation period were similar between intervention and control hospitals. Implementation period data were collected on 3727 infants, including 2328 boys (62%) and 1399 girls (38%), with a mean (SD) age of 6.0 (3.2) months. A total of 459 (12%) were Māori (New Zealand), and 295 (8%) were Aboriginal/Torres Strait Islander (Australia). Compliance with recommendations was 85.1% (95% CI, 82.6%-89.7%) in intervention hospitals vs 73.0% (95% CI, 65.3%-78.8%) in control hospitals (adjusted risk difference, 14.1%; 95% CI, 6.5%-21.7%; P < .001). CONCLUSIONS AND RELEVANCE: Targeted interventions led to improved treatment of infants with bronchiolitis. This study has important implications for bronchiolitis management and the development of effective interventions to deimplement low-value care.

    Understanding factors that contribute to variations in bronchiolitis management in acute care settings: a qualitative study in Australia and New Zealand using the Theoretical Domains Framework.
    (BioMed Central Limited, 1/05/2020) Haskell L; Tavender EJ; Wilson C; Babl FE; Oakley E; Sheridan N; Dalziel SR; Paediatric Research in Emergency Departments International Collaborative (PREDICT) nectwork, Australia
    BACKGROUND: Bronchiolitis is the most common reason for infants under one year of age to be hospitalised. Despite management being well defined with high quality evidence of no efficacy for salbutamol, adrenaline, glucocorticoids, antibiotics or chest x-rays, substantial variation in practice occurs. Understanding factors that influence practice variation is vital in order to tailor knowledge translation interventions to improve practice. This study explores factors influencing the uptake of five evidence-based guideline recommendations using the Theoretical Domains Framework. METHODS: Semi-structured interviews were undertaken with clinicians in emergency departments and paediatric inpatient areas across Australia and New Zealand exploring current practice, and factors that influence this, based on the Theoretical Domains Framework. Interview transcripts were coded using thematic content analysis. RESULTS: Between July and October 2016, 20 clinicians (12 doctors, 8 nurses) were interviewed. Most clinicians believed chest x-rays were not indicated and caused radiation exposure (beliefs about consequences). However, in practice their decisions were influenced by concerns about misdiagnosis, severity of illness, lack of experience (knowledge) and confidence in managing infants with bronchiolitis (skills), and parental pressure influencing practice (social influences). Some senior clinicians believed trialling salbutamol might be of benefit for some infants (beliefs about consequences) but others strongly discounted this, believing salbutamol to be ineffective, with high quality evidence supporting this (knowledge). Most were concerned about antibiotic resistance and did not believe in antibiotic use in infants with bronchiolitis (beliefs about consequences) but experienced pressure from parents to prescribe (social influences). Glucocorticoid use was generally believed to be of no benefit (knowledge) with concerns surrounding frequency of use in primary care, and parental pressure (social influences). Nurse's reinforced evidence-based management of bronchiolitis with junior clinicians (social/professional role and identity). Regular turnover of medical staff, a lack of 'paediatric confident' nurses and doctors, reduced senior medical coverage after hours, and time pressure in emergency departments were factors influencing practice (environmental context and resources). CONCLUSIONS: Factors influencing the management of infants with bronchiolitis in the acute care period were identified using the Theoretical Domains Framework. These factors will inform the development of tailored knowledge translation interventions.
