ORTIZ-ECHEVERRIA, María José  e  AVILA-DE BENEDICTIS, Lydiana. Factors associated with the use of antibiotic therapy in previously healthy children under 2 years old hospitalized for bronchiolitis. Acta méd. costarric [online]. 2022, vol.64, n.3, pp.13-21. ISSN 0001-6002.


Identify the patient characteristics and the factors related to the prescription of antibiotics, in all previously healthy children under 2 years of age hospitalized with a diagnosis of bronchiolitis, during a period of 12 months in a pediatric hospital.


descriptive observational study of the clinical-epidemiological characteristics of previously healthy children under two years of age hospitalized with a diagnosis of bronchiolitis, from January 1 to December 31, 2018 at the National Children's Hospital "Dr. Carlos Sáenz Herrera" of the Costa Rican Social Security, with a comparative analysis between the factors associated with the use or not of antibiotics during hospitalization.


A total of 261 previously healthy children hospitalized with bronchiolitis were included, with a mean age of 7.3 months and a predominance of males (n=160, 61.3%). 24.5% presented exposure to passive smoking. 66.1% of the patients had no history of wheezing prior to hospitalization and 52.2% had a family history of bronchial asthma. It was recorded that 17.2% (n=45) received antibiotics during their hospitalization. Factors associated with the prescription of antibiotics were the presence of pulmonary opacities (p=0.001, OR: 32.2) and bronchopneumonic infiltrates (p=0.002, OR: 2.72) on chest radiography, escalation to high-pressure cannula therapy flow (p<0.001, OR: 4.43) and assisted mechanical ventilation (p=0.001, OR: 7.17).


two factors that lead the physician to prescribe antibiotics in the healthy patient with bronchiolitis, the deterioration of the respiratory pattern that lead to intubation and ventilate the healthy patient with BQL and the presence of radiologic pulmonary opacities and bronchopneumonic infiltrates.
