The Development and Validation of a Cough Control Questionnaire
Chronic cough (\>8 weeks in duration) affects 5-12% of the global population, and is associated with considerable health status impairment and comorbidities. Currently, there are validated severity and impact outcome measures whilst objective measures with cough frequency monitoring is not available in routine clinical practice. Unlike other chronic respiratory diseases, namely asthma, there are no validated dedicated tools to assess the control of cough as a disease. This study aims to develop a validated patient-focused tool to assess the control of cough, which may be useful to evaluate the benefit and value of treatments in both clinical and research settings.
• Adult patients aged 18 and over with acute and chronic cough (including refractory chronic cough and unexplained chronic cough) and able to read and write in English. A smaller number (n =20) of healthy volunteers will also be included with no evidence of significant respiratory disease.
