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.
Individuals aged 20 years or older at the time of consent.
Individuals who have been prescribed inhaled medications and have been using them continuously for more than one month.
Prior experience with inhalation instruction is not required.
Individuals who have not been hospitalized within one month prior to study participation due to exacerbation of COPD.
Suffering from other respiratory diseases such as asthma or interstitial pneumonia
Suffering from advanced cancer, including lung cancer
Restricted chest movement due to chest deformity or trauma
Suffering from diseases that cause respiratory distress, such as heart disease
Parallel
inhalation management education
Behavioral* During interviews with researchers, undergo a technical check. Then, practice inhalation techniques. * During interviews with researchers, discuss solutions to symptoms and problems encountered in daily life. * Participants implement the solutions decided upon during the observation period. * During the second intervention, assess whether the solutions were effective and, if not, consider alternative solutions.
The Japanese version of the Pittsburgh Sleep Quality Index： PSQI-J
The PSQI-J is a questionnaire that asks about sleep patterns over the past month. It consists of 19 self-reported items and seven factors: sleep quality, sleep onset time, sleep duration, sleep efficiency, sleep difficulty, use of sleep medication, and daytime sleepiness. A total score of 0 to 3 points (0 to 21 points) is calculated, and the higher the score, the more severe the sleep disorder is considered to be.
Japanese Version of Epworth Sleepiness Scale：JESS
This is a self-assessment of the degree of sleepiness in eight daily-life situations. Each item is scored from 0 to 3(0-24 points), with higher total scores indicating greater daytime sleepiness. If the total score is 11 or higher, it is likely that the patient has SAS (sleep apnea syndrome).
Apnea-Hypopnea Index
Apnea-Hypopnea Index(AHI) is an index used to evaluate sleep apnea syndrome (SAS). It is calculated as the total number of observed apneas and hypopneas during sleep divided by the total sleep time (typically per hour). Diagnose with sleep apnea syndrome based on AHI\>5.
Depth of REM sleep
During REM sleep, estimates include the number and duration of wakefulness episodes and the proportion of REM time spent awake. The more times it occurs, the more it is considered to be disrupting sleep.
ODI
ODI (Oxygen Desaturation Index) is the number of oxygen desaturation events per hour of sleep. The number of events per hour in which SpO₂ drops by a certain percentage, usually 3% or 4%. Usually it's zero times.
