Abstract
INTRODUCTION: Bronchiolitis is a leading cause of infant hospitalization with wide variation in its diagnosis and management, especially in smaller community hospitals. The objective of this study is to describe children admitted to a community-based hospital emergency department (ED) for bronchiolitis and explore alternate assessments of illness severity. METHODS: A retrospective chart review (January to September 2014) of 100 children, < 2 years old and meeting International Classification of Diseases 10 for bronchiolitis. Outcomes included demographics, symptoms, and interventions. In addition, the Respiratory Distress Assessment Instrument (RDAI) score was calculated using documented assessments of wheezing and retractions. Descriptive and comparative statistics were completed with p < 0.05 considered significant. RESULTS: The mean (standard deviation) age 10.6 (8.4) months, n = 41 females. Sixty-seven percent had a chest X-ray (CXR), 17% oral antibiotics, 65% bronchodilators, and 19% oral steroids; 19% were admitted in hospital. There was a significant difference in RDAI score between those given oral antibiotics (mean (95% CI), 6.35 (4.96-7.75)) versus not (4.70 (4.20-5.20)), p = 0.01. Those who received a CXR had a significantly higher oxygen flowrate (1.4 (0.6-2.1) litres per minute (lpm)) and worse physical appearance (tri-pod position, head bobbing) versus those who did not (0.15 (-0.05 to 0.35) lpm), p = 0.002 and p = 0.04, respectively. CONCLUSIONS: A large number of children admitted to a community-based ED for bronchiolitis received unnecessary CXR and medications. Assessing physical and respiratory distress may be more effective at determining illness severity compared with radiological or laboratory testing. Local clinical practice guidelines may aid in optimal management of bronchiolitis for community-based EDs.
