The 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.

Most respondents were confident in their knowledge about treating COPD. Fewer respondents were confident about the use and maintenance of inhalation devices, and most respondents desired to learn more about inhalation devices.
