  1. aThe number of unscheduled healthcare events associated with poor inhalation technique is based on the increased risk of each event as reported by Melani and colleagues [19], taking account of the proportion of patients experiencing an event who have: i) good inhalation technique; ii) poor inhalation technique, but the reason for the event is not due to poor inhalation technique; iii) poor inhalation technique, and the poor inhalation technique is the cause of the event. The cost of poor inhalation technique was calculated by multiplying the number of events occurring per patient due to poor inhalation technique by the weighted cost of the event.bTotal number of unscheduled healthcare events and costs.
