Clinical COPD questionnaire (CCQ) in patients with COPD / 中国医师杂志

ABSTRACT

The overall impact of chronic obstructive pulmonary disease (COPD) on individuals is multifaceted and it causes impairment not only in lungs but also in other organs,and even in psychological conditions that result in multiple symptomatic effects and poorer quality of life.Therefore,it is critical to e valuate patients'quality of life in the clinical practice.Besides modified Medical British Research Council (mMRC) and COPD assessment test (CAT),the clinical COPD questionnaire (CCQ),a self-administered questionnaire was also recommended by GOLD2013 to assess patients'health status.Compared to the wide spread use of mMRC and CAT,CCQ was paid less attention in our clinical work.This study focused on the development,reliability,validity and responsiveness of the CCQ among subjects with COPD.We found that CCQ was easily understood with good reliability,validity and responsiveness and the use of the CCQ should be promoted as a health status measurement in more countries and regions.
