Evaluation of the Multidimensional Dyspnea Profile (MDP)
Evaluation of the Multidimensional Dyspnea Profile (MDP)
Aim of this multicenter prospective cohort study is the evaluation of the multidimensional
 qualities of dyspnea in a number of diseases using the Multidimensional Dyspnea Profile
 (Banzett et al, ERJ 2015).
The study sites will examine patients with COPD (Chronic obstructive pulmonary disease) in
 state of acute exacerbation and in stable state, patients with congestive heart failure (CHF)
 in state of acute decompensated cardiac insufficiency, and patients newly diagnosed with
 obstructive sleep apnea (OSA) as a control group.

 In the acute setting of COPD and CHF, the questionnaire will be given at the day of hospital
 admission and at the day of discharge. The patients will additionally fill the Severe
 Respiratory Insufficiency (SRI) Questionnaire (in COPD) or the Physical Activity
 Questionnaire 50+ (in CHF).

 In stable state of COPD, the questionnaires will be given once during a routine control visit
 at the hospital or the medical practice.

 In OSA, the questionnaire will be given once during the first visit in the sleep laboratory.
Inclusion Criteria:

 -  COPD patients with acute exacerbation (Group I)

 -  CHF patients with acute decompensation (group II)

 -  stable COPD patients (group III)

 -  OSA patients with AHI>15 (group IV)

 Exclusion Criteria:

 -  Other severe acute diseases that contradict the participation in a clinical trial

 -  Simultaneous participation in another clinical trial

 -  Not capable of giving consent

 -  Language abilities and other disabilities that contradicts the understanding or
 completing of a clinical questionnaire
