BACKGROUND AND OBJECTIVES International guidelines recommend against the use of bronchodilators in bronchiolitis. Despite attempts to address low value care practices in pediatrics, the literature is still evolving regarding which interventions are most effective in low value care reduction. We aim to assess the impact of a multifaceted intervention on rates of bronchodilator prescription in bronchiolitis. METHODS With electronic medical record (EMR) data over a 76- month period, we evaluated changes in bronchodilator prescription among infants aged 1 to 12 months diagnosed with bronchiolitis, using interrupted time series analysis, controlling for preintervention prescribing trends. The setting was the emergency department of a large teaching pediatric hospital. The intervention included education, clinician audit-feedback, and an EMR alert, implemented February 2019. The main outcome measure was rate of bronchodilator prescription per month. RESULTS There were 9576 infants, aged 1 to 12 months, diagnosed in the emergency department with bronchiolitis over the study period. Bronchodilator ordering reduced from 6.9% to 3.2% after the intervention. Once underlying trends were accounted for, the multifaceted intervention was associated with a reduction in the rate of prescribing (inter-rater reliability 0.98, 95% confidence interval 0.96 to 0.99, P = .037). CONCLUSIONS We found that the multifaceted intervention, including an EMR alert, may be an effective method of reducing low value care prescribing in bronchiolitis, accelerating the reduction of unnecessary care and supporting sustainable change.
