What this trial studies

This clinical trial aims to evaluate the effectiveness of a hand-held airways clearance device (OPEP) versus traditional chest physiotherapy exercises in patients with Chronic Obstructive Pulmonary Disease (COPD) who are experiencing excessive sputum production. Participants will be recruited from hospitals during exacerbations of COPD and will be randomized to receive one of the two interventions. The study will assess various outcomes including symptoms, quality of life, treatment burden, and hospital admissions over the course of one year. The goal is to determine which method is more effective in managing sputum clearance and improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 40-90 with a diagnosis of COPD, experiencing regular sputum production and currently admitted to the hospital or recently treated for an exacerbation.

Not a fit: Patients with contraindications to the OPEP device, unstable cardiac conditions, or a life expectancy of less than 12 months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective method for managing sputum clearance in COPD patients, potentially reducing hospital admissions and improving quality of life.

How similar studies have performed: While there is limited strong evidence supporting the effectiveness of cough clearance techniques, this study aims to fill a gap in the literature by directly comparing two methods in a randomized controlled setting.
