简要总结
The purpose of this study is to assess the efficacy of an internet-mediated pedometer based intervention that is designed to increase walking and improve function among veterans with chronic obstructive pulmonary disease (COPD). The Specific Aims are: 1) to test the effectiveness of an automated internet-mediated walking program for veterans with COPD with a primary outcome of improvement in health-related quality of life at four-months and at one year in a randomized controlled trial (RCT) with a wait list control. 2) to estimate the effect of internet-mediated walking program for veterans with COPD on all cause days of hospitalization over one year following randomization. 3) to compare intervention reach, participation and satisfaction outcomes between rural and urban veterans among those randomized to the intervention arm. The long-term objective of this research is to develop, evaluate and disseminate effective, low-cost interventions that improve quality of life for veterans, particularly rural veterans, managing complex chronic conditions.
详细描述
Background:
Low levels of physical activity are common in patients with chronic obstructive pulmonary disease (COPD), and a sedentary lifestyle is associated with poor outcomes including increased mortality, frequent hospitalizations, and poor health-related quality of life. Individuals with COPD who undergo a facility-based, exercise-focused pulmonary rehabilitation program experience significant improvements in health related quality of life, dyspnea, and exercise tolerance as well as reduced rates of hospitalization. Unfortunately, only a small percent of individuals with COPD who could benefit from pulmonary rehabilitation have access to and participate in such programs. Moreover, the benefits of short-term pulmonary rehabilitation programs tend to diminish rapidly after the program ends. Rural veterans are less likely to have access to facility-based pulmonary rehabilitation than urban veterans. Health related quality of life in rural veterans with COPD is significantly worse than for veterans with COPD who live in urban areas.
Objectives:
The primary objective of this study was to assess the efficacy of an Internet-mediated, pedometer-based intervention designed to increase walking and health related quality of life for Veterans with COPD. The specific aims of this randomized controlled trial (RCT) with a wait list control were: 1) To test the effectiveness of an automated internet-mediated walking program for veterans with COPD with a primary outcome of improvement in health related quality of life at four months and at one year; 2) to estimate the effect of the internet-mediated walking program for veterans with COPD on all cause days of hospitalization over one year following randomization; and 3) to compare intervention reach, participation and satisfaction outcomes between rural and urban veterans among those randomized to the intervention arm.
