• Conditions: Chronic Obstructive Pulmonary Disease Exacerbation; Chronic Pulmonary Disease; Chronic Obstructive Pulmonary Disease With Exacerbation
• Interventions: Device: bubble PEP

• Registration Number: NCT04828837
• Lead Sponsor: National Taipei University of Nursing and Health Sciences

Brief Summary

The morbidity rate of Chronic Obstructive Pulmonary Disease (COPD) is increasing year by year. It is predicted to be the third leading cause of death worldwide in 2030. People with COPD have a high risk of needing a ventilator due to the decline of lung function, the increase of secretions, the dysfunction of airway clearance, and the obstruction and loss of alveolar elasticity.

Detailed Description

This study aimed to explore the effectiveness of cough and sputum assessment and respiratory physiological indicators after training with the Bubble positive expiratory pressure (Bubble PEP) inpatients with COPD. This is a randomization control trial design survey using convenient sampling and will be to select 94 inpatients with COPD in the division of chest ward of two teaching hospital in New Taipei City. The subjects who meet the conditions for admission are explained, and they need to sign a consent form confirming that they understand the risks. More, they are randomly divided into the experimental group (experimental group n=47) and the control group (control group n=47). The experimental group receives the Bubble PEP training; the control group receives the division of chest ward routine care. The study employs a structured questionnaire including a basic demography, COPD domain, COPD assessment test (CAT), cough and sputum assessment test, and check the peak expiratory flow rate (PEFR) using it for data collection. The study needs to be approve by the Institutional Review Board. The two groups agreed to participate in the study, after completing the subject consent form before the intervention, they also received the pre-test as a benchmark for the intervention effect. After completing the 7-day and 30-day intervention, the post-test was performed immediately to understand the intervention immediate effect.

Primary Outcome Measures

Name	Time	Method
The Chinese Version of Chronic Obstructive Pulmonary Disease Assessment Test(CAT)	The pre-tests within 48 hours of hospitalization, which served as the baseline of the intervention (T0). Assessed at 1(T1) and 4(T2) weeks, week 4 was reported.	In the CAT, a total of eight items were used to assess the degree of dyspnea of the patients. Each item had a score ranging from 0 to 5 points, with the lowest total score being 0 points and the highest total score being 40 points. The higher the score, the higher the degree of dyspnea.
The Cough With Sputum Symptoms Assessment Questionnaire(CSSAQ)	The pre-tests within 48 hours of hospitalization, which served as the baseline of the intervention (T0). Assessed at 1(T1) and 4(T2) weeks, week 4 was reported.	CSSAQ is used to assess patients' cough and sputum symptoms. The questionnaire content is based on published literature. It consists of 25 questions, including issues related to cough, sputum, and psychological symptoms and impacts. The scoring uses a four-point Likert scale, with scores ranging from 0 to 4, where higher scores indicate more severe symptoms. The total scale score ranges from a minimum of 0 to a maximum of 100. The content validity index is 1, and the Cronbach's α is 0.97.
Peak Expiratory Flow Rate(PEFR)	The study lasted 30 days with a total of three measurements. The first measurement baseline was 48 hours after hospitalization, the second on day 7 of the study, and the third on day 30 of the study.	The TruZone peak flow meter is used to monitor the patient's Forced Expiratory Volume in the first second (FEV1). For each data collection session, three maximum expiratory flow tests are conducted, and the best value is taken as the result for that session. The measurement unit is ml/sec.

Secondary Outcome Measures

Name	Time	Method
Re-hospitalization Event	Within 14 days after discharge.	The number of patients who were readmitted due to COPD acute exacerbation (COPDAE) within 14 days after discharge during the study.
