    IntroductionNumerous studies show that patients with chronic obstructive pulmonary disease (COPD) perform an incorrect inhalation technique (IT). This research aims to describe inhalation errors committed and their clinical importance, and to identify factors related to them.Patients And MethodsA total of 995 patients were recruited in this cross-sectional, descriptive study that was conducted across 20 Andalusian Health Care Centres. The following variables were collected: socio-demographic data, quality of life, mental and cognitive status, spirometry tests, severity, number of IT devices, IT correct performance, previous instruction and clinical importance of errors.ResultsOf the 995 patients, 906 (91,1%) performed an incorrect IT. The most common errors showed moderate errors, which were related to low-cognitive level, low-peak expiratory flow and fewer medical consultations with the pulmonologist. Critical errors were correlated with greater severity, usage of Turbuhaler® and worse quality of life.DiscussionSoaring incorrect technique rate, whose most common errors sparingly compromise the drug effectiveness. These errors are related to the way the patients perform the IT, and not to the difficulty in handling the device. This information demonstrates the relevance of training patients in a proper way.Copyright © 2021 Elsevier España, S.L.U. All rights reserved.
