Predictive factors of asthma development in patients diagnosed with bronchiolitis include:
- Male sex (OR 1.3)
- Family history of asthma (OR 1.6)
- Age greater than 5 months at the time of bronchiolitis diagnosis (OR 1.4)
- More than 2 episodes of bronchiolitis (OR 2.4)
- Allergies (OR 1.6)
This was a retrospective study of 1991 children younger than 2 years that presented between 2000-2010 who were diagnosed with bronchiolitis. Primary care records were reviewed 1 year after their visit to the ED to see if the patient had a primary care diagnosis of asthma.
Of the initial study population, 817 patients had received a diagnosis of asthma at 1 year.
Since these patients were only followed up at 1 year, the amount of children who were later diagnosed with asthma may be underestimated.
