Pulmonary Rehabilitation for COPD Patients: Can Performance Predict Exacerbation?

Study Overview
=================
Brief Summary
-----------------
The aim of pulmonary rehabilitation is to improve exercise capacity and reduce dyspnoea. As well as improving the patient's overall condition, pulmonary rehabilitation provides a means to monitor the patient regularly. During physical exercise, the increased activity of the muscle system increases cardiac and respiratory output. If the patient's respiratory status deteriorates, as occurs, for example, before the onset of an exacerbation, exercise capacity could be reasonably expected to reduce. The investigators hypothesised, therefore, that changes in the physical capacity of patients with COPD during a rehabilitation session could provide a predictive indication regarding the risk of occurrence of exacerbation.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Correlation between the decrease of performance during pulmonary rehabilitation session and the occurrence of pulmonary exacerbation. | The change in performance rehabilitation of patients between the last session will be screen when a patients will be admitted to hospital for a COPD exacerbation. | From admission to the program or first documented session ; to completion of the pulmonary rehabilitation program or occurrence of an exacerbation, up to 104 weeks. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Correlation between the decrease of performance during pulmonary rehabilitation session and the COPD Assessment Test (CAT) questionnaire score. | The change in performance rehabilitation of patients between the last session will be screen and compared to a COPD Assessment Test (CAT) questionnaire score. | Through study completion, at every pulmonary rehabilitation session ; to completion of the pulmonary rehabilitation program or occurrence of an exacerbation, up to 104 weeks. |
