What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
CASA-Q Score	assessed with validated Coughing and Sputum Assessment Questionnaire (CASA-Q). Score between 0 and 100, with higher scores meaning less symptoms and less impact.	Baseline, 3 months, 6 months, 9 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of involuntary coughs per 24 hours	Patient reported, recorded by tally sheeting	Baseline, 3 months, 6 months, 9 months
Forced Expectoration	Patient reported, recorded by tally sheeting	Baseline, 3 months, 6 months, 9 months
Quality of Life by EQ-5D-5L	patient reported, the descriptive system assesses health in five dimensions, from which a health state index score is calculated, range from 0 to 1, with higher scores indicating higher health utility	Baseline, 3 months, 6 months, 9 months
Jenkins sleep evaluation questionnaire	Patient reported to assess sleep quality. Score between 0 and 20, with higher score the more sleep disturbances	Baseline, 3 months, 6 months, 9 months
Questionnaire to assess Shortness of Breath	from Ackerstaff et al., 1993	Baseline, 3 months, 6 months, 9 months
Voice handicap Index	patient reported outcome, score from 0-40, with higher scores indicating greater voice-related handicap.	Baseline, 3 months, 6 months, 9 months
Consumption of medical devices (Number of devices used)	Number of devices used, by use of patient diary recoding number of devices used	Baseline, 3 months, 6 months, 9 months
