From: The economic burden of asthma and chronic obstructive pulmonary disease and the impact of poor inhalation technique with commonly prescribed dry powder inhalers in three European countries

Unscheduled healthcare event Increased riska
Hospitalisation 47 %
ED visit 62 %
Course of antimicrobials 50 %
Course of OCS 54 %
Productive day lost 47%b
  1. aBased on the increased risk over patients with correct inhaler technique (odds ratio) of at least one critical inhaler error and self-reported utilisation of healthcare resources used in the year since the critical inhaler error [19]
  2. bConservatively assumed to be equal to the lowest increased risk reported for any unscheduled healthcare event (hospitalisation)
