COPD, Dyspnea, Stress
Conditions
Brief summary
This is a parallel design, randomized, controlled pilot trial comparing a controlled breath intervention (REST) to usual care for reducing stress in individuals with COPD.
Detailed description
This is a parallel design, randomized, controlled pilot trial comparing a controlled breath intervention (REST) to usual care for reducing stress in individuals with chronic obstructive pulmonary disease (COPD). The intervention is based on the breathing techniques of Pranayama. It was developed with patient and stakeholder input and is targeted for individuals with COPD who have moderate levels of stress and symptom burden. The intervention is a 15-minute breathing protocol which will be taught to participants and subsequently evaluated in a clinic setting with surveys, lung function, and cardiac assessments. This intervention will be pre-tested in 6 individuals, revised, and piloted in 30 individuals (15 in intervention group, 15 in control group). This study will answer the question of 1) whether a controlled breath protocol is feasible, acceptable, and safe for patients with COPD and 2) whether any modifications to the intervention are needed for a future multicenter trial to be proposed and conducted after the completion of the pilot trial. We will also 3) obtain sufficient estimates of variability in stress measures to inform statistical planning of a future trial.
Interventions
After randomization, individuals will attend an in-person training session in the REST protocol. This is a 15 minute controlled breath protocol that includes 3 yoga breathing techniques: 3-part dirgha breath, alternate nostril breathing, and 2:1 breathing. Each technique will be completed for 5 minutes, for a total of 15 minutes. After the training session, participants will practice the REST protocol for 15 minutes twice a day with guidance from research staff over zoom (Days 1-7) with daily COPD education including inhaler technique, nutrition, vaccinations, tobacco cessation counseling, and exacerbation education. On Day 8, participants will attend the Trial Session where they will complete the REST protocol (15 minutes) while vitals, lung function, and ECG measurements are taken. Surveys will be administered before and after the REST protocol to document patient reported stress and dyspnea.
After randomization, individuals will attend an in-person education session led by a research coordinator. For the following 7 days, the research staff will call patients daily and provide daily COPD education including inhaler technique, nutrition, vaccinations, tobacco cessation counseling, and COPD exacerbation education. On Day 8, participants will attend the Trial Session where they will do spontaneous breathing (15 minutes) while vitals, lung function, and EKG measurements are taken. Surveys will be administered before and after the spontaneous breathing period to document patient reported stress and dyspnea. After the study, participants will be asked to complete a close out survey and interview over zoom.

| Trial feasibility | 6 months | Rates of screening, enrollment, retention, reasons for exclusion and refusals, and attrition. Attrition goal \<10% throughout study period. |
| Acceptability (qualitative) | 6 months | Post-intervention semi-structured, in-depth interviews by telephone conducted by study coordinator to explore acceptability, barriers, facilitators, and survey burden |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mindful Attention Awareness Scale | Day 0, Day 8 | The MAAS is a 15-item scale designed to assess a core characteristic of dispositional mindfulness, namely, open or receptive awareness of and attention to what is taking place in the present |
| Perceived Stress Scale | Day 0, Day 8 | 10-item questionnaire with a score of 0-40, with higher scores indicating higher levels of stress. |
| Modified Medical Research Council dyspnea scale | Day 0, Day 8 | Self-rating tool to measure the degree of disability that breathlessness poses on day-to-day activities on a scale from 0 to 4 |
