[What is Important for Diagnosis and Therapy Follow-up in Chronic Cough?]. / Was ist für die Diagnostik und Therapieverlaufskontrolle von chronischem Husten wichtig?

Within the last years there has been significant progress in the field of chronic cough. So far, the analysis and evaluation of chronic cough was done mainly on the basis of subjective methods such as manual counts of cough events, questionnaires and diaries. Testing cough hypersensitivity and monitoring 24 h cough represent objective criteria. Validated questionnaires on cough frequency and quality of life represent the impact of chronic cough. Cough frequency monitoring, the preferred tool to objectively assess cough, should be used as primary end-point in clinical trials. It will also be possible to discriminate between productive and non-productive cough. The relationship with subjective measures of cough is weak. In the future, cough and its therapy should therefore be assessed with a combination of subjective and objective tools.
