Overview
Brief Summary
Pulmonary rehabilitation is well established as a treatment in COPD. After exacerbations of COPD, rehabilitation is associated with reduced frequency of exacerbations and improved exercise capacity. No data are available in bronchiectasis.
This study will randomly assign patients with bronchiectasis exacerbations to pulmonary rehabilitation or standard care. The hypothesis is that exercise capacity will be improved by pulmonary rehabilitation at 8 weeks.
Detailed Description
Background: Pulmonary rehabilitation is an effective treatment after exacerbations of COPD to prevent future exacerbations and to improve breathlessness and quality of life. Its effectiveness after exacerbations of bronchiectasis has never been demonstrated. Aims: To determine if a 6 week course of pulmonary rehabilitation improves exercise capacity at 8 weeks after exacerbation. Study Design: Randomised controlled trial. Methods: The study will take place in NHS Tayside. 40 patients with a history of bronchiectasis confirmed by HRCT will be included. Patients will be monitored using diary cards for exacerbations. At the onset of an exacerbation patients will be treated with a standard 14 day course of antibiotic therapy and randomised to one of two arms: Pulmonary rehabilitation or standard care. Patients randomised to pulmonary rehabilitation will undergo a 6 week course of supervised pulmonary rehabilitation. Patients will undergo study assessments (6-minute walk test, Quality of life questionnaires, pulmonary function tests (FEV1, FVC, FEF 25-75), symptoms recorded by symptom diaries and sputum microbiology).Assessments will be performed at the start and end of exacerbations, at 6-8 weeks post exacerbation (after completion of pulmonary rehabilitation in patients randomised to rehabilitation) and at 12 weeks. Outcome: The primary outcome is 6 minute walk distance at 8 week post exacerbation Expected Conclusion: We will determine the effectiveness of pulmonary rehabilitation after exacerbations of bronchiectasis.
