Study summary

This study will evaluate the diagnostic measures (including blood eosinophil counts) commonly used by lung specialist's in routine clinical care of subjects with COPD in Germany and how these diagnostic tests influence the physician's treatment decisions. The study will be conducted in three parts. In the first part, lung specialist's, who will not participate in the survey, will develop doctor's questionnaire. The second part is an interventional cross-sectional study, wherein approximately 30 lung specialists will be enrolled and data on their perspective on diagnosis and treatment of COPD subjects will be collected via the revised doctor's questionnaire. The third part is a retrospective non-interventional study where each doctor will collect retrospective data from selected subjects with COPD from the time of informed consent up to 12 months before. The retrospective data will be collected from subject files of approximately 250 subjects with COPD.

For subjects (Sample 2: 250 COPD subjects from these 30 doctors from sample 1)

  • Written informed consent to use his/her data.
  • Age >=40 years
  • Pack years >10, current or former smoking
  • Duration of COPD: >=1 year since COPD diagnosis record in subject files (also confirmed by spirometry)
  • No concurrent asthma diagnosis
  • At least one year of documented disease history at participating study doctors and have to be under the care of the before mentioned physician during this time because of COPD.

    Other: Doctor's questionnaire

  • Subjects with COPD

    Data from approximately 250 subjects with COPD under supervision of lung specialists enrolled in the study will be analyzed.

    Other: Subject file

Interventions

  • OtherDoctor's questionnaire

    The survey of physicians will be performed using doctor's questionnaire, which will be developed by lung specialists who are not participating in the survey.
