Cardio-pulmonary Rehabilitation and Sleep Quality
Cardio-pulmonary Rehabilitation and Its Impact on Sleep Quality; a Prospective Analysis

Detailed Description
Sleep disorders including poor quality of sleep are common in patients with heart failure, chronic obstructive pulmonary disease (COPD) and, possibly, other chronic lung disorders. These patients complain of difficulty sleeping and sleep fragmentation, often related to symptoms such as cough, sputum production or shortness of breath. Patients with COPD and heart failure commonly have other abnormalities such as nocturnal oxygen desaturation that may further worsen sleep disturbances. Moreover, sleep disordered breathing (SDB), like obstructive sleep apnea syndrome (OSA), has been linked to higher morbidity and mortality if COPD is present (known as Overlap syndrome). In patients with COPD and heart failure, cardio-pulmonary rehabilitation has important health benefits such as improvement in disease related symptoms, exercise tolerance, and health-related quality of life. However, the effect of cardio-pulmonary rehabilitation on sleep quality is controversial. Disturbed sleep is associated with frequent exacerbations, increase in the severity of disease and increased mortality in COPD and heart failure patients.
The investigators hypothesize that cardio-pulmonary rehabilitation results in improved sleep quality in patients with chronic lung disease and heart failure, this may be an important contributor to improved health outcomes after completion of cardio-pulmonary rehabilitation program.
The study will use data from questionnaires filled by the patients before and after completion of cardio-pulmonary rehabilitation. A 3-month follow up survey using the same questionnaires will be conducted to determine the longevity of improved sleep quality (if present). The questionnaires that will be used include Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), Berlin questionnaire, COPD assessment test (CAT) for COPD patients, Kansas city cardiomyopathy questionnaire (KCCQ) for heart failure patients, hospital induced anxiety and depression scale (HADS) and insomnia severity index (ISI).

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Patient with chronic lung or cardiac diseases
This study will focus on patients with obstructive or restrictive lung diseases eligible for pulmonary rehabilitation. Patient with cardiac disease such as heart failure, coronary artery disease or cardiomyopathies who are eligible for cardiac rehabilitation will also be included. |
Patients will undergo standardized cardio-pulmonary rehabilitation program.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Improvement in sleep quality using Pittsburgh sleep quality index
Time Frame: 8 weeks on average
|
Pittsburgh sleep quality index is validated questionnaire and will be used to determine improvement in sleep quality before and after completion of cardiopulmonary rehabilitation. Pittsburgh sleep quality index comprises of seven components. Each component is marked from 0 to 3, with a maximum total score of 21 and a minimum total score of 0. A score of less than 5 indicates good overall sleep quality and a score of 5 and more indicates poor sleep quality. From literature review using Pittsburgh sleep quality index, minimal clinically important difference was determined to be 3 between before and after measurements. |
8 weeks on average
|
Sleep apnea screening using Berlin questionnaire.
Time Frame: Through study completion which is approximately one year.
|
Berlin questionnaire will be used to screen for sleep apnea in individuals who are to begin cardiopulmonary rehabilitation and do not have a known diagnosis of sleep apnea.
Investigators will specifically look for the percentage of patients who are at high risk for sleep apnea based on Berlin questionnaire (positive score on 2 out of 3 categories of the questionnaire) in the cardio-pulmonary cohort.
|
Through study completion which is approximately one year.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Effect of cardio-pulmonary rehabilitation on disease specific health related quality of life.
Time Frame: 8 weeks
|
Hospital anxiety and depression scale is self-reported questionnaire tool to screen for anxiety and depression with two subscales (one of anxiety and one for depression). Each subscale has a minimum score of 0 and maximum score of 21. A cut-off of 11 or more indicates probable mood disorder. COPD assessment test will be used for COPD patients. COPD assessment test consists of 8 items with a minimum score of 0 and a maximum score of 40. A score of 10 or more suggests presence of significant lung disease. Kansas city cardiomyopathy questionnaire consists of 23 items with a minimum score of 0 and a maximum score of 100. A score of less than 25 signifies presence of poor heart function. Change in mean scores before and after rehabilitation will be determined and paired student t-test will be used to determine if the change in scores is significant. |
8 weeks
|
Correlation between sleep quality and disease specific health related quality of life.
Time Frame: 8 weeks
|
Correlation between change in disease specific health status as determined by the questionnaires (HADS, CAT and KCCQ) after cardio-pulmonary rehabilitation and change in sleep quality as determined by Pittsburgh sleep quality index will be determined by using Pearson's correlation coefficient (r).
|
8 weeks
|
Change in insomnia severity index
Time Frame: 8 weeks.
|
Insomnia severity index will be determined before and after cardiopulmonary rehabilitation.
Insomnia severity index consists of 7 items with a minimum total score of 0 and maximum total score of 28 with a score of 8 or more suggesting presence of insomnia.
A 6 point change is considered significant (minimum significant important difference) as determined by literature.
Paired student t-test will be used to compare means before and after cardio-pulmonary rehabilitation
|
8 weeks.
|
Longevity of sleep improvement
Time Frame: 3 months.
|
Pittsburgh sleep quality index questionnaire will be administer 3-months after completion of cardio-pulmonary rehabilitation if there is improvement in sleep quality at the end of cardio-pulmonary rehabilitation.
The mean scores from end of rehabilitation and 3-months after completion of cardio-pulmonary rehabilitation will be compared using paired student t-test.
|
3 months.
