De-escalation of High-flow Respiratory Support for Children Admitted with Bronchiolitis: A Quality Improvement Initiative.

Academic Article


  • UNLABELLED: Bronchiolitis is the most common cause for hospitalization in the first year of life, with hypoxemia and acute respiratory failure as major determinants leading to hospitalization. In addition, the lack of existing guidelines for weaning and discontinuing supplemental oxygen, including high-flow nasal cannula, may contribute to prolonged hospitalization and increased resource utilization. METHODS: This single-center quality improvement initiative assessed the effect of implementing a standardized care process for weaning and discontinuing high-flow oxygen for patients hospitalized with bronchiolitis. Patients aged 1-24 months with bronchiolitis admitted to the general wards or ICU step-down unit from February 1, 2018, and January 31, 2020 were included in the study. Primary outcomes included length of stay and time on supplemental oxygen, with time on high-flow oxygen and length of time in ICU step-down unit as secondary outcomes. Balancing measures included transfer rate to Pediatric Intensive Care Unit, intubation rate, 7- and 30-day readmission rates, and 7- and 30-day ED visits after discharge. RESULTS: Following the standardized care process implementation, the mean length of stay decreased from 60.7 hours to 46.7 hours (P < 0.01). In addition, the mean time on any supplemental oxygen decreased by 47% (P < 0.01), the mean time on high-flow oxygen decreased by 45% (P < 0.01), and the mean time in the ICU step-down unit decreased by 27% (P =< 0.01). Balancing measures remained unchanged with no statistically significant differences. CONCLUSION: Implementing a standardized care process for weaning and discontinuing high-flow oxygen may reduce the length of stay and resource utilization for patients hospitalized with bronchiolitis.
