Minimal Clinically Significant Difference (MCID) of Multidimensional Dyspnea Profile (MDP) in COPD Patients Undergoing Respiratory Rehabilitation (DYSCO)
Determination of the Minimal Clinically Significant Difference (MCID) of Multidimensional Dyspnea Profile (MDP) Scores in Chronic Obstructive Pulmonary Disease (COPD) Patients During Pulmonary Rehabilitation

Detailed Description
The aim of the research is to determine the minimal clinically significant difference (MCID) in MDP scores in COPD patients after a respiratory rehabilitation course using the anchoring method :
- The A1 score will be compared with the Borg Affective Dyspnea (BorgA) scale.
- The sensory score will be compared with the Borg Sensory Dyspnea Scale (BorgS).
- The 5 sensory items will be compared with the Borg Sensory Dyspnea scale.
- The emotional score will be compared with the Borg Emotional Dyspnea Scale.
- The 5 emotional items will be compared with the Borg affective dyspnea scale. The various questionnaires will be administered to patients at inclusion, after a constant work-rate cycling exercise test, and at isotime during the same cycling exercise test at the end of the pulmonary rehabilitation course.
The sensitivity study will be conducted using the visual analog dyspnea scale instead of the Borg score. Finally, we will also determine the MCID using the distribution method. The MCID score will be correlated with various quality of life and physical performance scores.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: pulmonary rehabilitation
COPD patients will be admitted for pulmonary rehabilitation, the duration and modalities of which vary from center to center.
|
Description: at the end of pulmonary rehabilitation, a constant work-rate second cycling exercise test will be performed with the same duration as the cycling exercise test at inclusion
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
multidimensional (MDP) questionnaire
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
The multidimensional questionnaire measuring the sensory component of dyspnea (intensity of the 5 respiratory descriptors) and the affective component of dyspnea (immediate discomfort and intensity of emotional responses).
The MDP will be carried out at the end of the constant work-rate cycling exercise test, taking into account the last 30 seconds.
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
sensory Borg scale
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
The two Borg scales will be carried out at the end of the constant work-rate cycling exercise test, taking into account the last 30 seconds.
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
affective Borg scale
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
The two Borg scales will be carried out at the end of the constant work-rate cycling exercise test, taking into account the last 30 seconds.
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Affective and Sensory dyspnea visual analog scale (VAS)
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
Affective and sensory dyspnea VAS will be carried out at the end of the constant work-rate cycling exercise test, taking into account the last 30 seconds.
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
mMRC (Modified Medical Research Council) dyspnea score
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
This 5-level score assesses the intensity of dyspnea.
The consideration period will be one week.
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
Dyspnoea 12
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
Multidimensional dyspnea questionnaire comprising 12 items (7 sensory and 5 affective) that can be rated from 0 (absent) to 3 (severe), i.e. a score from 0 to 36.
This questionnaire measures dyspnoea over the period "these days".
The consideration period will be one week
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
COPD Assessment Test (CAT) score
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
This questionnaire comprises 8 questions on a scale from 0 (best condition) to 5 (worst condition).
The total score corresponds to the sum of the scores for each question: it ranges from 0 to 40.The consideration period will be one week.
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
Hospital Anxiety and Depression scale (HADS)
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
Anxiety and depression, measured by the two subscore of the HADS scale.
Each subscore comprises 7 items rated from 0 (no symptoms) to 3. Seven questions relate to anxiety (total A) and seven questions relate to depression enabling us to obtain the score (maximum score = 42)The consideration period will be one week.
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
Saint George Respiratory Questionnaire (SGRQ)
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
evaluated by a total score and three sub-scores (symptoms, activity and impact).
The total score and each sub-score are scaled from 0 to 100.
The higher the score, the poorer the quality of life.The consideration period will be one week.
|
at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
VQ11
Time Frame: at inclusion and then, up to 6 weeks (at the end of pulmonary rehabilitation course)
|
questionnaire consisting of 11 questions evaluated by a total score and 3 sub-scores (functional - 3 items, psychological: 4 items; relational - 4 items).
Each question has 5 possible response levels, with ratings on a Likert scale ranging from 1 (not at all) to 5 (extremely).
The functional, psychological and relational scores are respectively rated out of 15 for the first and 20 for the last two.
The total score ranges from 11 to 55.
A VQ11 total score greater than or equal to 22 reflects a patient's poor health-related quality of life.
|
