WHAT THIS STUDY ADDS:In this study, antibiotic use was found to be 1.9 times more frequent in children who were treated with asthma drugs than those who were not. Among children who received an asthma drug, 35.6% were dispensed an antibiotic on the same day. abstract BACKGROUND: In children, antibiotics as well as asthma drugs are frequently prescribed. We investigated the effects of the codispensing of antibiotics and asthma drugs to children.
METHODS:Using a health insurance database, we examined dispensing and codispensing of antibiotics and asthma drugs for the period of a 1 year in 892 841 Belgian children aged Ͻ18 years.
RESULTS:For a 1-year period, an antibiotic was dispensed to 44.21% of children: 73.05% aged Ͻ3 years; 49.62% aged 3 to 7 years; and 34.21% aged 8 to Ͻ18 years. An asthma drug was dispensed to 16.04% of children: 44.81% aged Ͻ3 years; 17.90% aged 3 to 7 years; and 7.64% aged 8 to Ͻ18 years. Overall, an antibiotic was dispensed without an asthma drug to 38.62% of children versus with an asthma drug to 73.50% of children (P Ͻ .0001). More frequent dispensing of antibiotics to children who received an asthma drug (odds ratio: 1.90; 95% confidence interval: 1.89 -1.91) occurred in all age categories (P Ͻ .0001). In 35.64% of children with an asthma drug dispensed, an antibiotic was dispensed on the same day.
CONCLUSIONS:In all age groups, dispensing of antibiotics is more likely in children who have an asthma drug dispensed in the same year. In all age groups, codispensing of antibiotics and asthma drugs is a common practice. Efforts to decrease antibiotic use in children could be improved by focusing on children who are being treated with asthma drugs.
