[Comparison of adherence as assessed by the Test of Adherence to Inhalers and Pharmacy Refill Records, in Asthma Patients. REFARMA study].

Introduction: Clinical guidelines recommend the combined use of "self-completed questionnaires such as the Test of Adherence to Inhalers (TAI)" and the pharmacy refill rate (PRR) to determine adherence, but evidence based on comparative studies to support these recommendations is limited. Our objective was to determine adherence to inhalers in asthmatic patients, using the TAI and the PRR, as well as the correlation and concordance between both methods.

Methods: Multicentre cross-sectional study including the first 196 consecutive adult asthmatic patients, of whom 183 were on maintenance treatment with Inhaled Corticosteroids (ICS).
