The independent risk factors that affect the hospitalization of acute bronchiolitis

Abstract

Abstract:Aim: The aim of this study is to find out the independent risk factors that affect the period of hospitalization in acute bronchiolitis. Material and Methods: The patients who were hospitalized with the diagnosis of bronchiolitis at the Pediatric Emergency and Intensive Care Unit were included. Results: 61 (64 %) of the patients were males and 34 (36%) were females. The median age of the patients was 7 (1.5-23) months. The median hospitalization period was 6 (3-18) days. Factors affecting prolonged acute bronchiolitis were premature birth history (p=0.005), infant age group (p=0.03), breastfeeding < 2 months (p=0.02), tachypnea in admission (p<0.001), wheezing in admission (p<0.001), retraction in admission (p=0.045), apnea (p=0.021), cyanosis (p=0.032). In the logistic regression analysis which was conducted for independent risk factors that increased the risk of prolonged acute bronchiolitis, premature birth history, breastfeeding less than 2 months, wheezing in admission and tachypnea in admission were found to be independent risk factors that affected the length of hospitalization. Premature birth history increased acute bronchiolitis risk 3.74 times (95% CI:1.19-11.8; p=0.024), while tachypnea in admission increased the risk 3.54 times (95% CI:1.15-10.9; p=0.028), wheezing increased 3.6 times (95% CI:1.13-11.4; p=0.030) and breastfeeding for less than 2 months increased the risk 3.11 times (95% CI: 1.12-8.6; p=0.03). Conclusion: In conclusion, premature birth history, wheezing in admission, tachypnea in admission and breastfeeding less than 2 months were found to be independent risk factors for prolonged acute bronchiolitis.
