Portable Oxygen Concentrator to Improve Quality of Life in Chronic Obstructive Pulmonary Disease

N/ACompletedNCT01948544

StratiHealth27 enrolled

Overview

* Evaluate subjects in an prospective observational study * Subjects will be administered scientifically validated questionnaires * Determine the affect of the Portable Oxygen Concentrator (POC) on improvements in: 1. Exercise capability, dyspnea and quality of life as primary endpoints 2. Utilize: 1. Baseline Dyspnea Index (BDI) 2. Transitional Dyspnea Index (TDI) 3. Chronic Respiratory Disease Questionnaire (CRQ) 4. Six minute walk test (6MWT) 5. Epworth Sleepiness Scale (ESS) * The secondary endpoints will be: 1. Rate of exacerbations, sleep quality 2. Health care utilization (emergency room encounters, hospital admissions)

Evaluate subjects in an prospective observational study in which subjects will be screened and administered scientifically validated questionnaires at study entry and during the observation period at specified intervals to determine the affect of the Portable Oxygen Concentrator on improvements in exercise capability, dyspnea and quality of life as primary endpoints, utilizing the Baseline Dyspnea Index (BDI), Transitional Dyspnea Index (TDI), the Chronic Respiratory Disease Questionnaire (CRQ) and six minute walk test (6MWT). The secondary endpoints will be rate of exacerbations, sleep quality (reported as number of hours sleep improvement; utilize Epworth Sleepiness Scale \[ESS\]), and health care utilization (emergency room encounters, hospital admissions).

Outcomes

Primary Outcomes

Functional Capacity

Change in functional capability, dyspnea - BDI/TDI • Change in exercise capability - 6MWT

Time frame: 6 months

Quality of Life Using Chronic Respiratory Disease Questionnaire

Quality of life - Chronic Respiratory Disease Questionnaire

Time frame: Measure Dyspnea at baseline upon study entry and change from baseline every two weeks up to three months; Numerical, 7-point modified Likert Scale; Total score and subscores on categories; higher scores indicate better health-related quality of life
