Predictive Questionnaires for Risk of Acute COPD (Chronic Obstructive Pulmonary Disease) Exacerbations
COPD patients frequently suffer intermittent exacerbations of their disease characterised by acute deterioration of symptoms. Acute exacerbations of COPD (AECOPD) are associated with significant impairment of health status, use of health care resources, poor prognosis and increased mortality. The development of simple and practical predictive tools would help to identify COPD patients at greater risk of suffering exacerbations, which is important since those patients would need more intense and early treatment.
This one-year prospective cohort non-drug study will evaluate several COPD-specific questionnaires as predictive tools and the presence of cardiovascular comorbidities as risk factors, for the composite events in study cohorts. The trial duration consists of a screening period (4-6 weeks) and a follow-up period (12 months), 4 visits in total along the study.

|Official Title:||Comparative Evaluation of COPD Specific Quality of Life Assessment Questionnaires (the COPD Assessment Test, the Clinical COPD Questionnaire, the COPD Severity Score and the Airways Questionnaire 20 as Predictive Tools for Risk of Acute COPD Exacerbations|
- Comparative evaluation of the predictive value of the COPD Assessment Test (CAT), Clinical COPD Questionnaire (CCQ), COPD Severity Score (COPDSS) and the Airways Questionnaire 20 (AQ20) questionnaires (in hospital) [ Time Frame: one year ]Comparative evaluation of the predictive value of the CAT, CCQ, COPDSS and the AQ20 questionnaires for the composite event of mortality and re-hospitalization for COPD, in a one year follow-up of a cohort of COPD patients admitted for an exacerbation, enrolled in hospital.
- Comparative evaluation of the predictive value of the CAT, CCQ, COPDSS and the AQ20 questionnaires (in primary care) [ Time Frame: one year ]Comparative evaluation of the predictive value of the CAT, CCQ, COPDSS and the AQ20 questionnaires for the composite event of any exacerbation, mortality and hospitalization for COPD, in a one-year follow-up of a cohort of COPD patients enrolled in primary care.
- To evaluate cardiovascular comorbidities as risk factors for the composite events in the hospital and the primary care cohorts. [ Time Frame: one year ]
