Oral corticosteroid prescription patterns for asthma in France, Germany, Italy and the UK.


ABSTRACT: Oral corticosteroids (OCS) are used to manage asthma exacerbations and severe, uncontrolled asthma, but OCS use is associated with adverse effects. We aimed to describe the patterns of OCS use in the real-world management of patients with asthma in western Europe.We used electronic medical records from databases in France, Germany, Italy and the United Kingdom from July 2011 through February 2018. Patients aged ?12?years with an asthma diagnosis, at least one non-OCS asthma medication within ±6?months of diagnosis, and available data ?6?months prior to and ?90?days after cohort entry were included. High OCS use was defined as OCS ?450?mg prescribed in a 90-day window during follow-up. Baseline characteristics and OCS use during follow-up were described overall and by OCS use status.Of 702?685 patients with asthma, 14-44% were OCS users and 6-9% were high OCS users at some point during follow-up. Annual prevalence of high OCS use across all countries was ?3%. High OCS users had a mean of between one and three annual OCS prescriptions, with an average daily OCS dosage of 1.3-2.2?mg. For patients who continued to meet the high-use definition, daily OCS exposure was generally stable at 5.5-7.5?mg for ?2?years, increasing the risk of adverse effects.Our study demonstrates that OCS use is relatively common across the four studied European countries. Data from this study may provide decisive clinical insights to inform primary care physicians and specialists involved in the management of severe, uncontrolled asthma.
