OBJECTIVES For patients hospitalized with bronchiolitis, many hospitals have implemented clinical practice guidelines to decrease variability in care. Our hospital updated its bronchiolitis clinical pathway by lowering goal oxygen saturation from 90% to 88%. We compared clinical outcomes before and after this change within the context of the pathway update. METHODS This was a retrospective analysis of patients <24 months old admitted to a pediatric tertiary care center from 2019 to 2021 with bronchiolitis. Patients with congenital heart disease, asthma, home oxygen, or admitted to an ICU were excluded. The data were stratified for patients admitted before and after the clinical pathway update. Statistical methods consisted of 2 group comparisons using the χ-square test for categorical variables, the Wilcoxon rank-sum test for continuous variables, and multiple regression analysis. RESULTS A total of 1386 patients were included, 779 preupdate and 607 postupdate. There was no statistically significant difference in the admission rate of patients presenting to the emergency department with bronchiolitis between the 2 groups (P value .60). The median time to room air was 40.0 hours preupdate versus 30.0 hours postupdate (P value < .001). The median length of stay was 48.0 hours preupdate versus 41.0 hours postupdate (P value < .001). Readmission rate was 2.7% within 7 days of discharge preupdate, and 2.1% postupdate (P value .51). CONCLUSIONS Decreasing goal oxygen saturation to 88% was associated with a statistically significant decrease in time spent on oxygen and length of stay for patients admitted with bronchiolitis with no increase in readmissions.
