The role of inhalation delivery devices in COPD: Perspectives of patients and health care providers

Background: Inhaled medications form the foundation of pharmacologic treatment for chronic obstructive pulmonary disease (COPD). The Delivery Makes a Difference (DMaD) project was conducted to better understand health care provider (HCP) and patient perspectives about the role of inhalation delivery devices in COPD, and to examine the nature of educational efforts between HCPs and patients on proper device technique. Methods: Data were derived from 2 original quantitative, web-based, descriptive, cross-sectional surveys distributed to HCPs who manage COPD (n=513) and patients with COPD (n=499) in the United States. Descriptive statistics were used to assess data across important demographic variables. Inferential statistics were used to assess differences in attitudinal, descriptive, and behavioral measures that were cross-tabulated with demographic data. Results: When prescribing medication for newly diagnosed patients with stable or unstable COPD, only 37% of HCPs considered type of device to be highly important, with only 45% of HCPs assessing device technique in every newly diagnosed patient. Patients with COPD were also relatively unconcerned with proper device technique (64% never concerned), regardless of their COPD severity. Although patients did not identify education as a significant impediment to proper device use, they reported inconsistent educational experiences. Conclusions: We found that HCPs and patients prioritize medication over device when selecting treatments, showing limited concerns about proper device use. These results highlight the need to coordinate professional education with patient-directed educational efforts to further promote proper device selection and use in COPD management.
