SANCHEZ D., Ignacio et al. Epidemiological and clinical characteristics of patients hospitalized due to acute bronchiolitis in Santiago. Rev. chil. pediatr. [online]. 2004, vol.75, suppl.1, pp.25-31. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41062004000700005.

Introduction: Acute bronchiolitis (AB) is a frequent respiratory disease in infants. Objectives: To compare epidemiological characteristics of two groups of patients hospitalized due to AB in two hospitals with different SE conditions and to evaluate clinical management and hospital evolution. Methods: We performed a prospective clinical questionnaire between May and October 2002 to parents of infants younger than 2 years admitted with diagnosis of AB at the Pediatric Services of Universidad Católica (HUC) and Sótero del Río (HSR), including general information, epidemiological and previous disease. Clinical presentation and hospital evolution were recorded. Results: A total of 130 questionnaires were done in HSR and 93 in HUC. Mean age was 2,5 ± 0,2 months in HSR vs 6,6 ± 0,6 in HVC (p < 0,0001), with a predominance in males in both centers. Parental education was different (19,2% primary, 70% secondary and 10,7% university in HSR vs 2,15 primary, 37,6% secondary and 60.2 university in HUC p < 0,0001). Day care attendance was different (2,3% in HSR vs 16,1% in HUC, p < 0,0001). Kerosene heating was present in 46,1% in HSR vs 8,6% in HUC (p < 0,001), passive tabacco smoke was 38% in HSR vs 22% in HUC (p < 0,02). Clinical management showed significant differences in several aspects, such as: days of admission (mean of 5,2 days, 4 in HSR vs 4,4 days, in HUC p < 0,001). Adrenaline was given to 81,5% patients in HSR vs 44% in HUC (p < 001) and chest physiotherapy to 86% infants in HSR and 54% in HUC (p < 0,0001). Clinical complications were not different in both groups. Conclusions: Acute bronchiolitis can affect infants independent of their SE conditions. Despite of different SE status, clinical evolution and complications were not different
