Predictors of Outcome of Bronchiolitis in Children Using Children Hospital of Wisconsin Respiratory Score: An Experience of a Tertiary Care Hospital

Abstract

Objective: To study the correlation of CHWR score and its various clinical markers with the length of stay in hospital bronchiolitis. Study Design: Cross-sectional analytical study. Place and Duration of Study: Department of Pediatrics Combined Military Hospital, Lahore Pakistan, from Nov 2018 to Apr 2019. Methodology: This study included children aged 2 to 24 months, clinically diagnosed with bronchiolitis. The Receiver Operator Characteristic (ROC) was used to determine the discriminative validity of the CHWR score in predicting the length of stay. Results: One hundred thirty-eight children of either gender were enrolled in the study. The median age of the study population was 10.8 (9) months. ROC curve showed significant discriminate validity of CHWR score and its component criterion on admission. CHWR score of >10.5 predicted a longer stay (>24 hours) in ICU. Pearson correlation showed a statistically significant positive correlation between CHWR score at admission and length of stay (r=0.831, p=<0.001). Conclusion: CHWR scoring system on admission is an easy, safe and effective way to classify bronchiolitis severity and thus help predict the length of stay.
