Brief 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).

Outcome Measures

Primary Outcomes (1)

  • Feasibility of intervention

    intervention 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.

    through study completion, average 1 year

Secondary Outcomes (7)

  • Leicester cough questionnaire

    through study completion, average 1 year

  • The King's Brief Interstitial Lung Disease (KBILD)

    through study completion, average 1 year

  • Modified Borg scale (mBorg)

    through study completion, average 1 year

  • Cough Hypersensitivity Questionnaire (CHQ)

    through study completion, average 1 year

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

    through study completion, average 1 year

  • +2 more secondary outcomes

Study Arms (1)

Non-pharmacological Cough control therapy

EXPERIMENTAL

Participants will attend four virtual sessions of 45 to 60 minutes of educational and self-management. Sessions will be designed to target participants' needs and expectations according to the semi-structured theme. Session 1 General assessment Prescription of cough technique Session 2 Cough principles of cough Cough control Session 3 Breathing pattern retraining and laryngeal hygiene Session 4 Reinforcement of cough control therapies

Other: Non-pharmacological Cough control Therapy

Interventions

Participants will attend four virtual sessions of 45 to 60 minutes of educational and self-management. Session 1 General assessment Prescription and taught of one cough suppression technique. Session 2 Cough principles: mechanism, cough reflex, chronic cough, the importance of cough and negative effects of repeated coughing. Cough control: identify triggers, use cough suppressions and distractions techniques. Session 3 Breathing pattern retraining and laryngeal hygiene: reinforce nasal breathing and pursed lips breathing as strategies to avoid the urge to cough, identification of risk factors for laryngeal dehydration and hydration education. Session 4 Reinforcement: Clarification of doubts, techniques' reinforcement and application during daily life situations.
