title: Inhaler use in chronic obstructive pulmonary disease.
abstract: Inhaler technique is a common problem, particularly in the elderly. We have assessed the ability to use seven common inhaler devices in 20 patients with chronic obstructive pulmonary disease (COPD). Techniques were taught in a standard fashion in random order and assessed immediately and one hour later by two observers. Fourteen patients had a fault that would result in no drug delivery at some time during the study, and such a fault occurred at some point for each inhaler device. These faults were most common with the diskhaler. Accuhaler, autohaler and turbohaler scored highest and diskhaler lowest. Overall scores declined by one hour after instruction. Patients ranked the metered dose inhaler and accuhaler highest for ease of use and preference. These results show that it is useful to have a small range of devices for patients with COPD and that it is important to review inhaler technique regularly.
