Overview
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.

Outcomes
Primary Outcomes
Acceptability (qualitative)
Time Frame: 6 months
Post-intervention semi-structured, in-depth interviews by telephone conducted by study coordinator to explore acceptability, barriers, facilitators, and survey burden
Acceptability (quantitative)
Time Frame: 6 months
Post-intervention survey on intervention acceptability with Likert scale rated 1 to 10; 10 being most acceptable. Overall average score ≥8 of 10 defined as acceptable. Will assess patient reported enjoyment, difficulty, and adherence
Intervention Feasibility
Time Frame: 6 months
IG: Completion of 2 in-person sessions (1 training, 1 trial) along with \>80% of daily individual practice of breathing protocol (15 minute twice daily)
Trial feasibility
Time Frame: 6 months
Rates of screening, enrollment, retention, reasons for exclusion and refusals, and attrition. Attrition goal \<10% throughout study period.
Secondary Outcomes
- Modified Medical Research Council dyspnea scale(Day 0, Day 8)
- Mindful Attention Awareness Scale(Day 0, Day 8)
- Perceived Stress Scale(Day 0, Day 8)
