Clinical Effectiveness Of High Frequency Chest Wall Oscillation (HFCWO) In A Bronchiectasis Population

Study Overview
=================
Brief Summary
-----------------
The primary objective is to compare the patient's baseline QoL prior to HFCWO use against the patient's QoL at various study timepoints over a one-year period of HFCWO use.

Detailed Description
-----------------
This study will use a prospective interventional comparative study design using the patient's quality of life (QoL) as the primary study endpoint to determine HFCWO affect. The study will compare the patient's QoL baseline (established at enrollment prior to HFCWO treatment) to the QoL measured at various timepoints (enrollment, 2 months, 6 months and 12 months) over a one-year period whilst receiving HFCWO treatment. In addition, a baseline for the secondary endpoints will established at enrollment for comparison to measurements taken at various timepoints over a one-year period whilst receiving HFCWO treatment. The patient's medical records will be used to establish prior histories of exacerbation rates for comparison to exacerbation rates experienced after one year of HFCWO treatment. Patients will serve as their own control.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of Life (QoL): Quality of Life-Bronchiectasis (QOL-B) questionnaire | The primary endpoint is the subject's quality of life (QoL) using the Quality of Life-Bronchiectasis (QOL-B) questionnaire as the measurement tool. QoL measured at enrollment (baseline) will be compared to QoL measured at 2 months, 6 months and 1 year. The previously validated questionnaire is titled Quality of Life Questionnaire - Bronchiectasis. The Likert style questionnaire asks the subject to subjectively rank their symptoms using a 4 scale base ranging from a lot of difficulty to no difficulty and always to never. | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinical Measurements | Exacerbation rates a. Pre HFCWO exacerbation rates will be established by review of the patient's medical records. Post HFCWO will recorded at 2 months, 6 months and 1 year. Exacerbation frequency The time to the subject's next exacerbation will be recorded for comparison pre to post HFCWO Lung function (FEV1, FVC, FEF25-75) measured by standard spirometry Sputum production measured by using the Breathlessness, Cough and Sputum Scale (BCSS) questionnaire Patient adherence to HFCWO treatment measured by SmartVest Connect wireless feature Six-minute walk test measured using American Thoracic Society standard test guidelines/protocol Radiographic changes compare patient's original high-resolution computerized tomography (HRCT) taken to initially | 1 year |
