Abstract
• A computer file system was used in our pediatric allergy clinic to assess the value of chest roentgenograms and hemoglobin determinations used in the examination of patients and to correlate exposure to pets and forced hot air with the severity of asthma. Among 889 children with asthma, 20.7% had abnormal chest roentgenographic findings, excluding hyperinflation and peribronchial thickening, and 0.7% had abnormal hemoglobin values. Environmental exposure to pets or forced hot air was not associated with increased severity of asthma, as assessed by five measures of outcome: number of medications administered, requirement for corticosteroids, frequency of clinic visits, frequency of emergency room visits, and frequency of hospitalizations.
