BACKGROUND AND OBJECTIVE: Bronchiolitis is a common disease in early childhood with increasing healthcare utilization. We aim to study how well a simple and improved respiratory score (the modified Respiratory Index Score [RIS]) would perform when predicting for a warranted admission. METHODS: This is an observational prospective study, from June 2015 to December 2015 in a paediatric emergency department (ED) of a large tertiary hospital in Singapore. We included @entity1 aged less than 2 years old, presenting with typical symptoms and signs of @entity5924 but excluded @entity1 with four or more previous wheezes, a gestation of <35 weeks, and known @entity66 . We also performed a sensitivity analysis for @entity1 presenting with their first wheeze. We defined a warranted admission as a composite of: The need for airway intervention, intravenous hydration, and a hospital stay of 2 days or more. RESULTS: Among 1,818 @entity1 , the median age was 10.8 months (IQR 7.2-15.9). The median modified RIS score was 4.0 (IQR 3.0-5.0). A total of 19 (1.0%) @entity1 required respiratory support, 101 (5.6%) received intravenous hydration, and 571 (31.4%) required a hospital stay of 2 days or more. After adjusting for age and duration of illness, a modified RIS score of >4 predicted significantly for a warranted admission (adjusted Odds Ratio: 3.28, 95% confidence interval: 2.62-4.12). The association remained significant among @entity1 presenting with their first wheeze. CONCLUSIONS: This simple respiratory tool predicts for the need for respiratory support, intravenous hydration, and a significant hospital stay of 2 days or more.
