Inhaler usability of a pressurized metered dose inhaler and a soft mist inhaler in patients with COPD: A simulated-use study.

ABSTRACT: The objective of this study was to evaluate task performance and handling errors with soft mist inhalers (SMIs) or pressurized metered-dose inhalers (pMDIs) among patients with chronic obstructive pulmonary disease (COPD) experienced with, but not recently trained in, using these devices. This exploratory, noninterventional, simulated-use study (D5970R00004) assessed handling/usability of SMIs and pMDIs in inhaler-experienced patients with COPD (40-78 years; diagnosis ≥6 months). Patients received a device and instruction-for-use leaflet but no training and were recorded while performing tasks required for checking the device, priming, and dosing. Errors that could substantially affect the lung-delivered dose were considered critical. Sixteen of 61 patients (52% male) had used SMIs and 55
