PurposeThere are very few studies on primary adherence (i.e., first filling of a prescription) to inhaled corticosteroids (ICS) in asthma patients; two have involved children. Moreover, adherence can be overestimated when considering only secondary adherence (i.e., following the medication recommendations for a defined period) and ignoring primary adherence. We aimed thus to evaluate the real-world primary and secondary adherence to ICS and to develop an integrated primary and secondary adherence (IPSA) measure.
