Patterns of topical corticosteroids prescriptions in children with asthma

Abstract

Objectives: To study topical corticosteroid use in Dutch asthmatic children using pharmacy dispensing data and to assess whether Dutch physicians prescribe topical corticosteroids in this population according to clinical guidelines. Methods: Medication histories of children using asthma medication were extracted from the pharmacy dispensing system in 100 Dutch community pharmacies. The incidence rate and the potency of topical corticosteroid prescriptions per age were assessed. The topical corticosteroid incidence rates of the different age groups were compared using the Pearson chi-square test. Generalized linear models were used to study the prescription behavior of general practitioners and atopic dermatitis-related specialists regarding different classes of topical corticosteroids. Results: Thirty percent of the infants received a topical corticosteroid prescription, compared with 15%-18% of the children aged 4 and older. Similarly, the mean number of topical corticosteroid prescriptions in infants was 2.2 per year, compared with 1.6-1.9 in children aged 4 and older. In concordance with the clinical guidelines, we observed that atopic dermatitis-related specialists more often prescribed first prescriptions of potent and very potent topical corticosteroids than general practitioners (relative risk = 2.55, 95% confidence interval = 1.79-3.63).
