Patient perception of metered-dose inhaler use and its implications in
COPD management.
Abstract
Objectives: Literature has shown a high prevalence of poor inhaler
technique among COPD patients throughout the past several decades. We
aim to study patient perspectives on inhaler use to understand how
inhaler therapy can be better approached. Methods: COPD patients who
were regularly using pressurized metered-dose inhaler(s) (pMDI) with or
without spacers were recruited to complete a survey regarding their
perception of inhaler use. Each patient’s inhaler technique was assessed
using the American Thoracic Society (ATS)’s recommended steps on using
pMDIs. Results: One hundred and one patients participated in the study.
91 (90.1%) reported that they use their inhaler correctly and 80
(79.2%) indicated that using their inhaler is easy, however 47 (46.5%)
demonstrated inhaler misuse. 35 (34.7%) indicated that they prefer to
consolidate all of their inhalers into one. When asked about previous
training, 25 (24.8%) reported that they have not been shown how to use
inhalers before. Conclusions: Despite the high prevalence of poor
inhaler use, the majority of COPD patients are confident in their
inhaler technique and find them easy to use. Increasing patient
awareness of poor inhaler technique and providing more frequent coaching
on how to correctly use pMDI’s may be beneficial in improving overall
COPD management.
