A Non-pharmacological Cough Control Therapy

Cough Clinical Trial

Official title: A Non-pharmacological Cough Control Therapy as an Adjuvant of Pulmonary Rehabilitation in People With Interstitial Lung Diseases and Chronic Cough - A Feasibility Study

Status Recruiting

Clinical Trial Summary

Coughing affects almost all individuals with ILD leading to physical, psychological and social distress and prevents individuals from performing their activities of daily living, working or socialising in public places. Unfortunately, there are no licensed medications available to treat chronic cough and the few drugs that have been tried resulted in little efficacy and significant side effects. Drug-free cough control interventions have shown promise in reducing the severity and impact of coughing on patients' lives but have not been tested in individuals with ILD. This study aims to explore the feasibility and effectiveness of a non-pharmacological cough control therapy, as an adjuvant of pulmonary rehabilitation, in patients with ILD and chronic cough (>8 weeks in duration).

Clinical Trial Description

Research questions and hypotheses

i) Is a non-pharmacological cough control therapy feasible to treat chronic cough in patients with ILD? Hypothesis: Given the results of previous non-pharmacological interventions in patients with refractory cough, we predict that this intervention will be feasible and well accepted in patients with ILD.

ii) Is a non-pharmacological cough control therapy more effective than pulmonary rehabilitation (PR) alone to treat chronic cough in patients with ILD? Hypotheses: Given the results of previous non-pharmacological interventions in patients with refractory cough, we predict that improvements observed in participants receiving the non-pharmacological intervention will exceed those receiving PR alone. Improvements are expected in HRQOL (exceeding the minimal clinically important difference), intensity of cough-related sensations and symptoms of fatigue.

Research Design The proposed research is a feasibility pre-post intervention study.

Study details:

Adults with ILD and chronic cough will be enrolled in this study. Potential eligible patients will be recruited from the outpatient PR program at West Park Healthcare Centre and St. Joseph's Healthcare. As the outpatient pulmonary rehabilitation program at West Park Healthcare Center and St. Joseph's Healthcare will transition partially to virtual meetings, the interactions between the research team and patients will be completed via phone calls or online.

This research study will be delivered online using the Zoom Healthcare Plan, an online platform that is available at West Park Healthcare Centre, and is used for telerehabilitation programs. Participants will be enrolled into a PR program composed of aerobic and strengthening exercises, disease-specific education and self-management, as part of their usual care. Two weeks before termination of PR, participants will start the non-pharmacological cough control therapy, following the intervention proposed by Chamberlain colleagues (2017). Participants will attend four virtual sessions of 45 to 60 minutes of educational and self-management

This study will measure several clinical outcomes.

1. Feasibility will be reflected by the number of eligible patients enrolling (enrolment rate of at least 75%) and completing the intervention (attendance rate of at least 80%), compliance with the sessions and adverse events.

2. Leicester cough questionnaire

3. The King's Brief Interstitial Lung Disease (KBILD)

4. Modified Borg scale (mBorg

5. Cough Hypersensitivity Questionnaire (CHQ)

6. Functional Assessment of Chronic Illness Therapy Fatigue Scale (FACIT-F)

7. Global rating of change questionnaire (GRCQ)

8. Satisfaction Semi-structured interviews using open-ended questions will be conducted before and after the cough control intervention to capture participants' expectations and perspectives about the cough control therapy. ;
