NCT02725294
This observational study will examine the care-seeking behaviors of Veterans with chronic obstructive pulmonary disease (COPD) to see whether patients' perceived need for care or lack of access to care leads to delays in getting care for COPD exacerbations. Participants complete a baseline in-person visit and receive calls every two weeks for one year to monitor for COPD exacerbations. Detailed information about each exacerbation and time to care are obtained. A sample of participants and their caregivers participate in in-depth interviews. Approximately half the participants will also use a remote inhaler monitor to record their albuterol inhaler use to see if this approach can identify early exacerbations. Results from this study will be used to develop an intervention that will assist Veterans in the early identification, evaluation, and treatment of exacerbations, and will be integrated with the VA primary care team.
NCT02506504
In patients with severe Chronic Obstructive Pulmonary Disease (COPD), exercise tolerance is severely impaired due to a ventilatory limitation, levelling off the intensity of exercise. This reduces the physiological benefit of pulmonary rehabilitation. In these patients, it is then proposed to add an Inspiratory Pressure Support (IPS) in order to increase the intensity and the duration of every training session. In a preliminary study, the investigators showed that IPS applied during an exhaustive cycling exercise allowed to prevent the onset of post-exercise quadriceps fatigue evaluated by the endurance time to isotonic quadriceps contractions (TlimQ). The aim of this study is to determine the relationship between the prevention of post-exercise fatigue (TlimQ) and the change in training load (intensity x time x number of sessions) during a pulmonary rehabilitation programme. At the beginning of the training programme, 25 patients will be evaluated for TlimQ after a cycling exercise (70% maximal workload) with and without IPS in random order. The training load was then monitored at every exercise session of the programme.
