Objective: There is no definitive consensus on asthma exacerbation scoring for preschool children with recurrent wheezing. The Clinical Asthma Score (CAS) and Asthma Severity Score (ASS) are two scoring systems that can be used in this population. The aim of this study was to evaluate the relationship between CAS and ASS, acute treatment, and exacerbation outcomes in preschool children with wheezing.

Materials and Methods: The study included 70 patients aged 2-5 years who presented to the pediatric emergency department due to an acute wheezing episode. CAS and ASS were evaluated at exacerbation presentation and after initial salbutamol therapy.

Results: Presenting scores were significantly higher among patients who had three or more episodes within the last year (p=0.01 for CAS, p=0.019 for ASS). Presenting scores were significantly higher in patients treated with systemic steroid therapy during the episode compared to those who were not (p=0.006 for CAS; p=0.003 for ASS). CAS and ASS predicted the use of acute steroid therapy with a sensitivity of 73.7% and 52.6%, and predicted hospitalization with a sensitivity of 95% and 82.5%, respectively.

Conclusion: Our data suggest that these scoring systems can be used to judge the need for systemic steroid therapy and that high scores are associated with greater likelihood of hospital admission.
