The independent risk factors that affect the hospitalization of acute bronchiolitis

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.

Breastfeeding and family history of atopy as predictors of clinical course for acute uncomplicated bronchiolitis in infants: a prospective, longitudinal, cohort study.

“…Epidemiological evidence has shown that breastfeeding human milk is a protective factor against the development of multiple diseases, including AB, due to the high transmission of immunological factors present in breast milk. [23][24][25][26] A recent systematic review showed that exclusive and partial breastfeeding reduces the severity of the disease, length of hospital stay and supplemental oxygen requirement. This review demonstrated that hospitalized infants were signi cantly more likely to be breastfed for less than 6 months.…”
