Differential Effect of Modified Medical Research Council Dyspnea, COPD Assessment Test, and Clinical COPD Questionnaire for Symptoms Evaluation Within the New GOLD Staging and Mortality in COPD.
Chest
July 2015
Article Synopsis
- - The study aimed to evaluate how well the COPD Assessment Test (CAT), Clinical COPD Questionnaire (CCQ), and Modified Medical Research Council (mMRC) dyspnea scores predict mortality in patients with Chronic Obstructive Pulmonary Disease (COPD).
- - Researchers analyzed data from 768 COPD patients over an average follow-up of 38 months, finding that higher scores on all three assessments were linked to increased mortality.
- - Although the CAT and CCQ have similar predictive abilities for all-cause mortality, they were not as effective as the mMRC dyspnea scores, leading to suggestions for new scoring thresholds for better risk assessments.
Objective: The COPD Assessment Test (CAT) has been proposed for assessing health status in COPD, but little is known about its longitudinal changes. The objective of this study was to evaluate 1-year CAT variability in patients with stable COPD and to relate its variations to changes in other disease markers.
Methods: We evaluated the following variables in smokers with and without COPD at baseline and after 1 year: CAT score, age, sex, smoking status, pack-year history, BMI, modified Medical Research Council (mMRC) scale, 6-min walk distance (6MWD), lung function, BODE (BMI, obstruction, dyspnea, exercise capacity) index, hospital admissions, Hospital and Depression Scale, and the Charlson comorbidity index.
Rationale: Little is known about the longitudinal changes associated with using the 2013 update of the multidimensional GOLD strategy for chronic obstructive pulmonary disease (COPD).
Objective: To determine the COPD patient distribution of the new GOLD proposal and evaluate how this classification changes over one year compared with the previous GOLD staging based on spirometry only.
Methods: We analyzed data from the CHAIN study, a multicenter observational Spanish cohort of COPD patients who are monitored annually.
