BackgroundSuccessful inhalation therapy depends on the ability of patients with COPD to properly use devices. We explored subjects' COPD knowledge, including education they receive from health care providers, treatment experiences, and practices with inhalation devices.MethodsA multiple-choice online survey, developed by a steering committee of American Thoracic Society clinicians and scientists, was administered to subjects with COPD who were sourced from the Harris Poll Online panel.ResultsOf the 254 respondents (mean age 61.8 y; 49% males), most subjects (82%) claimed to understand their disease and available treatments, yet COPD symptoms and causes were well known to only 45% and 44% of subjects, respectively. Forty-three percent of subjects had ever used a pressurized metered-dose inhaler or dry-powder inhaler. Of the 54% of subjects who had ever used a small-volume nebulizer (SVN), 63% considered this device to be easy to use, 55% considered it to be fast-acting, 53% considered it to be convenient, and 38% considered it to be essential for treatment. Among subjects who had ever used them, SVNs were preferred by 54% over other devices. One third of subjects desired more extensive education during office visits; 25% felt the time was insufficient to cover questions, and 15% felt their concerns about COPD treatment(s) were ignored. Subjects believed physicians (32%), nurses (26%), and no single provider (28%) were primarily responsible for training and assessing proper inhalation technique.ConclusionThe survey showed differences between patients' beliefs and knowledge of COPD; the need for continuous education from health care providers, particularly on inhalation devices; and extensive use of pressurized metered-dose inhalers and dry-powder inhalers despite positive perceptions of SVNs.Copyright © 2018 by Daedalus Enterprises.
