This study aims to investigate whether inhalation management education provided by nurses improves sleep quality in patients with COPD. Inhalation management education includes training in inhalation techniques and guidance on how to use medications when symptoms occur.
The main research question is:
・Does inhalation management education improve sleep quality in patients with COPD?
Researchers will determine whether inhalation management education improves sleep quality compared to no education.
Participants will:
* Participate in two interviews with researchers using video conferencing tools.
* Keep a diary recording their symptoms, sleep duration, and the frequency of rescue inhaler use.
