10. RespirTech’s bronchiectasis patient outcomes program consists of follow-up calls at periodic intervals for up to two years to encourage HFCWO adherence and ensure the device is properly set for individual needs.
11. Methodology: Phone surveys at regular intervals with bronchiectasis patients using the InCourage system. Data collection began 10/01/2013. As of 05/31/2021, the total cohort was 23,213 patients; 21,049 patients completed the baseline survey; 13,303 patients in 1-month cohort; 9,569 in 6-month cohort; 7,720 in 12-month cohort
