Official title
Interpreting COPD Dyspnea Change: Sensitivity, Responsiveness, and Predictive Validity of the Dyspnea Management Questionnaire Computer Adaptive Test (DMQ-CAT)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Dyspnea, or uncomfortable labored breathing, is an important patient-reported outcome (PRO). It is the primary and most disabling symptom of chronic obstructive pulmonary disease (COPD). There is a high priority to improve dyspnea PRO assessment and predict exacerbations. Frequent exacerbations are associated with increased disability, decreased quality of life (QOL), and accelerated lung function decline. Goals: To test the relative sensitivity to change, responsiveness and predictive validity of a comprehensive dyspnea outcome computer adaptive test (CAT) that measures new anxiety and activity avoidance domains and is more efficient to administer than existing dyspnea scales. Expected Outcomes: Investigators expect to: 1. begin to transform how dyspnea is assessed; 2. improve dyspnea symptom management; 3. impact functional status; 4. improve QOL; 5. facilitate the earlier treatment and prevention of exacerbations; 6. improve COPD prognosis and survival; and 7. improve COPD healthcare utilization.
