Abstract

PURPOSE
This study was aimed to investigate the clinical and epidemiological characteristics of the patients with acute bronchiolitis who visited in 146 Emergency Departments (EDs) in Korea in 2012.
METHODS
We used the NEDIS (National Emergency Department Information System) database to obtain all children with acute bronchiolitis who visited ED under the age of 3 between January 1, 2012 and December 31, 2012.
RESULTS
Totally 18,313 children with acute bronchiolitis were enrolled at this study. The male to female ratio was 1.55:1 and mean age was 10 months. The peak proportion was 17.3% in November during the whole year. The most common chief complaints were fever (38.5%), cough (37.4%), dyspnea (9.5%), gastrointestinal symptom (6.7%), and wheezing (2.5%). The most common accompanying disease was pneumonia (13.3%). The rate of hospital admission and intensive care unit admission were 34.5% and 0.3%, respectively. A predictor for admission via ED was respiratory difficulty.
CONCLUSION
These data expand our understanding of clinical characteristics of patients with acute bronchiolitis who visited all ED in Korea in 2012.
