简要总结
This a 70 patient multi-site non blinded randomized control trial evaluating the use of the Vest® System for treatment of Non-Cystic Fibrosis Bronchiectasis (NCFBE) patients in the home setting. The study will assess outcomes in subjects requiring airway clearance therapy randomized to Oscillating Positive Expiratory Pressure (OPEP) therapy as the control group and High Frequency Chest Wall Oscillation (HFCWO) therapy as the intervention group
详细描述
Patients with NCFBE who require regular home airway clearance therapy will be eligible to be screened for inclusion in the study.
After enrollment, baseline data including demographics, pulmonary related medical history including acute exacerbations (pulmonary-related hospitalizations, ED visits and physician office visits) will be collected Pulmonary function tests (PFTs) (spirometry), and a six-minute walk test will be completed. Quality of Life measures and inflammatory markers and will be collected.
Patients will be randomized to HFCWO or OPEP therapy. Each device will be used within the approved product labeling. These will be the primary airway clearance devices for these patients during the 12 months of the study period.
Following enrollment in the study and completion of a baseline visit, subjects will be seen for follow-up visits.
Detailed documentation of health status and medical history will be collected during the 12-month study period and/or at each study visit to document the occurrence of acute exacerbations and to determine time to first exacerbation, number of hospitalizations and hospitalization days, number of ICU admissions and ICU days, and number of outpatient visits (Physician's office visit, Urgent Care Visits, ED visits)

结局指标
主要结局
Frequency of acute exacerbations of bronchiectasis
时间窗: 12 months
