About
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:
Full description
●Research participants, eligibility criteria, and exclusion criteria The study will include stable COPD patients who are outpatients at Kumamoto University Hospital, Kounan Hospital, or Iwakuni City Nishiki Central Hospital, which specialize in internal and respiratory medicine. Eligible participants must meet all of the following criteria and must not meet any exclusion criteria.
【Eligibility Criteria】
【exclusion criterias】
Presence of other respiratory diseases such as asthma or interstitial pneumonia.
Presence of advanced cancer, including lung cancer.
Restricted chest movement due to chest deformity or trauma
Sleep-disordered breathing with a central apnea-hypopnea index (AHI) exceeding 50%.
Sleep-disordered breathing with a central AHI of more than half
Diagnosis of dementia or other psychiatric disorders.
Following the pre-established random allocation table, participants will be sequentially assigned to each treatment group in the order of case registration, and a registration confirmation form will be issued, indicating the participant's registration number and treatment group. The allocation table will be retained by the allocation officer and will not be disclosed to the principal investigator or co-investigators.
●Sample size Target number of participants (Total: 34 cases) Intervention group: 17 cases Control group: 17 cases Number of participants expected to enroll(Total: 60 cases) Intervention group: 30 cases Control group: 30 cases There are no previous studies measuring the effect of inhalation management education on sleep quality. In previous studies, the average PSQI score for COPD patients was 8.3-11.5 points, and the PSQI cutoff value is 5.5 points. Assuming a change of 5.0 points in the average PSQI-J score after 3 months in the intervention group, the sample size required to maintain a two-sided test (significance level 5%) with 80% power is 17 cases per group. Considering that many participants are elderly and may have difficulty continuing to use computers or video conferencing tools, a higher dropout rate than usual is anticipated. Therefore, 30 participants per group, totaling 60 participants, will be enrolled in the study.
●Criteria for exclusion from analysis The definition of the analysis population is as follows.
-Full Analysis Set (FAS) The FAS consists of all study subjects who provided informed consent, excluding the following study subjects.
The PPS is defined as the FAS excluding the following subjects:
• Cases with unavailable measurements of the primary endpoint
• Cases with major protocol violations (e.g., allocation errors, failure to meet eligibility criteria, non-compliance with medication)
This study will clearly identify the breakdown of cancellations and dropouts by compiling data on the number of registered subjects who were excluded from the analysis population and the reasons for their exclusion, broken down by analysis population.
●Analysis and statistical methods for verifying evaluation items Statistical analysis will be performed using JMP Pro 18, with a significance level set at 5%.
-Analysis of primary endpoints Primary endpoint: Change in PSQI-J at 3 months before and after the educational intervention The primary endpoint will be analyzed using the FAS. The change in PSQI-J scores will be calculated for each group, and independent t-tests will be performed to compare groups at a significance level (two-sided) of 5%. A similar analysis will be conducted using PPS as the analysis population as a secondary analysis.
-Using FAS as the analysis population, the difference in the mean change in JESS, Japanese CAT, and HADS scores between groups will be analyzed using a paired t-test at a significance level of 5%. Similar analyses will also be conducted using PPS as the analysis population.
In this study, baseline data for the primary outcome measure, PSQI, were missing at study registration. If PSQI-J was measured within one month of baseline (prior to the first intervention), that data was used to impute baseline data for PSQI-J. This method of data imputation may result in the presence of data from different measurement time points at baseline.
However, since the PSQI-J reflects sleep quality over the past month and no interventions were conducted during that period, this method of data supplementation is considered appropriate. For other items, missing values will not be supplemented.
Information on patients obtained at baseline from participants who withdrew from the study or withdrew their consent will be used for analysis if consent is obtained from the participants themselves, as it constitutes valuable data on inhalation techniques, inhalation education, and methods for current COPD patients.
●Criteria for discontinuing participation in research The principal investigator or co-investigator shall terminate the study if they determine that it is impossible to continue the study for any of the following reasons.
<Termination Criteria>
• If a research subject withdraws from the study or revokes their consent
• If it is determined after registration that the subject no longer meets the eligibility criteria (inclusion/exclusion criteria)
