Brief summary
The Time-based Register and Analysis of COPD Endpoints (TRACE) study is prospective cohort study aiming at evaluating COPD patients using simple basic tools normally used in the clinic at hand of any physician. The objective of the study is to accomplish specific aims. 1) describing the disease variation over time. 2) defining different disease behaviours; and 3) evaluating the impact of different therapeutic approaches on this behaviour in the different patient types. TRACE is a single center non-interventional prospective observational cohort study of COPD patients. Upon identification of cases, patients are followed-up in yearly visits sine die until death or lost to follow-up. Starting in 2012, during the yearly visits clinical, functional, radiological and analytical information is recorded via a standardized questionnaire. Variables recorded were: socio-demographics, tobacco history, comorbidities, clinical presentation during the previous year, exacerbations and hospitalization in the previous year, current pharmacological and non-pharmacological treatments, and complementary tests, including at least chest radiology, pre- and post-bronchodilator spirometry, and analytical results. Endpoints include a variety of clinically relevant variables including disease phenotypic expression, diagnostic measures and therapeutic responses.
Detailed description
The Time-based Register and Analysis of COPD Endpoints (TRACE) study is prospective cohort study aiming at evaluating COPD patients using simple basic tools normally used in the clinic at hand of any physician. To include new cases, a retrospective review of patients who meet the inclusion / exclusion criteria will be done. For this, proceed as follows: the COPD-dedicated outpatient clinic of the principal investigator will be reviewed to evaluate all the patients that were evaluated in this consultation. Once identified, those who are still in follow-up will be selected and the data will be collected for inclusion. Subsequently, the patients included will be followed up prospectively with annual visits until their death or loss of follow-up, as per clinical practice in our institution
