The REALISE Survey

The REALISE Survey of 8,000 patients with asthma, across 11 European countries, identified significant levels of suboptimal asthma control. A new analysis of the data reveals how patients with differing needs could benefit from targeted approaches in consultations to better manage their asthma1. View this infographic to find out how.

The CRITIKAL study

The CRITIKAL (CRITical Inhaler mistaKes and Asthma controL) study was the first study to investigate the relationship between inhaler technique errors and asthma outcomes2. View this infographic to find out what common errors were identified, and how the right inhaler plus training by healthcare professionals could improve patient outcomes.

Watch this short animation of the results of the REALISE Survey into the extent of uncontrolled asthma in Europe, and the CRITIKAL Study into the association between inhaler technique errors and poor asthma control. Professor David Price then explains their significance and what clinicians can do to improve outcomes for their patients with asthma.
