However, poor asthma control is common, despite available effective treatment .This is partially related to low adherence and to difficulties in using inhaler devices. Among patients with chronic respiratory disorders, 18% discontinued the prescribed inhaler treatment because of troubles with the device (Santus 2012). Some devices are not easy to handle, or require breathing abilities, which reduce the effectiveness in real life, especially in elderly.Since mistakes in inhaler technique are very common affecting drug delivery and efficacy, a correct inhaler technique training is fundamental. A single site study in 2012 (Press 2012) found that patients given verbal and written instructions followed by demonstrations of inhaler use had better inhaler technique than patients given verbal and written instructions only. The authors concluded that larger multi-centred studies were needed to evaluate hospital-based-education.
