RT Journal Article SR Electronic T1 Comparison of an innovative multi-dose inhaler with the attributes of an 'ideal' inhaler: A multicentre randomised controlled trial (RCT) JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP P937 VO 44 IS Suppl 58 A1 Spencer Jones A1 Roger Clarke A1 Stephen Eason A1 Phil Swanbury A1 Alison Scrimgeour A1 Nicky Ellis YR 2014 UL http://erj.ersjournals.com/content/44/Suppl_58/P937.abstract AB Several studies have defined the attributes of an 'ideal' inhaler, which include ease of use and patient (pt) acceptability. A secondary endpoint of a 76-centre global (US, EU and SE Asia) RCT aimed to evaluate the subjects' operation and handling of Forspiro®, an innovative dry powder inhaler. The study involved 373 pts with mild to moderate asthma who had previously used a range of other inhalers. Attributes were assessed via a 10-component questionnaire.Ease of use, pre-dose preparation, cleaning, visibility of remaining doses, comfort and convenience were all considered important or very important attributes by >80% pts. Fishbein multi-attribute analysis showed a high degree of correlation between the attributes of an ideal inhaler and pts' belief of how these apply to Forspiro®. The majority of pts agreed or strongly agreed that overall, Forspiro® is easy to use (98.8%), easy to open and get ready (98.2%), easy to clean (97.3%), comfortable to hold (97.3%), and convenient to carry around (94.7%) (Fig). Over 90% of pts agreed or strongly agreed that they would be satisfied if their current inhaler were replaced with Forspiro®.The Forspiro® device was well received and a high proportion of pts would be satisfied if it replaced their current inhaler. The majority of pts stated that Forspiro® possesses many attributes that correlate with those of an ideal inhaler.
