Design outcomes

Primary

MeasureTime frame
Mean number of exacerbations over 52 weeks; exacerbations diagnosed as they occur via interview with patients and completion of the Respiratory and Systemic Symptoms questionnaire (RSSQ)

Secondary

MeasureTime frame
1. Disease-specific health-related quality of life (HRQoL) at 52 weeks measured using the respiratory symptoms domain of quality of life with bronchiectasis (QoL B) questionnaire completed at baseline, 2 weeks, 8 weeks, 26 weeks and 52 weeks 2. Time to next exacerbation post-randomisation measured in days, with exacerbations diagnosed as they occur via interview with patients and completion of the RSSQ 3. Number of days of antibiotics related to exacerbations over 52 weeks assessed via interview with patients at 2, 8, 26 and 52 weeks 4. Generic health-related quality of life (HRQoL) measured using the EQ-5D-5L questionnaire at baseline, 2 weeks, 8 weeks, 26 weeks and 52 weeks 5. Health Service use over 52 weeks assessed via completion of a questionnaire completed at baseline, 2 weeks, 8 weeks, 26 weeks and 52 weeks 6. Quality Adjusted Life Years (QALYs) over 52 weeks calculated by assessment of generic HRQoL measured using the EQ-5D-5L questionnaire completed at baseline, 2 weeks, 8 weeks, 26 weeks and 52 weeks 7. Health impairment measured using the St George’s Respiratory Questionnaire (SGRQ) at baseline, 2 weeks, 8 weeks, 26 weeks and 52 weeks 8. Patient preferences for treatment measured using a Treatment Satisfaction Questionnaire at 2, 8, 26, and 52 weeks 9. Adverse events over 52 weeks recorded as they occur by the PI or designee via interview with patients 10. Lung function over 52 weeks measured by spirometry testing at baseline, 2 weeks, 8 weeks, 26 weeks and 52 weeks 11. Adherence to HTS and carbocisteine over 52 weeks assessed via interview with patients at 2, 8, 26, and 52 weeks
