About

This is a multi-country, multicentre, observational prospective data collection cross sectional study of patients with stable COPD in Latin America. Primary objective is to assess and characterize COPD symptoms over a period of 24 hours, by collecting information about the respiratory symptoms experienced at different times of the day and night-time in patients with stable COPD under real clinical practice conditions. Correlation between each of these symptoms and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification, adherence to respiratory treatment, level of dyspnea, disease severity, comorbidities and physical activity as well direct costs will be done as secondary objectives. Study population are patients of 40 years and older, smokers or ex smokers of >= 10 pack/years with previous COPD diagnosis, attending outpatient specialists consults in Argentina, Chile, Colombia, Uruguay, Costa Rica, Guatemala and Mexico. Sample size is targeted to 900 enroled patients in order to ensure 860 patients to achieve statistical power to primary objective.

Full description

This is a multi-country, multicentre, observational prospective data collection cross sectional study of patients with stable COPD in Latin America. Primary objective is to describe prevalence, severity and interrelationship of early morning, day and night-time symptoms in patients with stable COPD in Latin America (LatAm). Secondary objectives are to evaluate the relationship between early morning, day and night-time symptoms and 2013 GOLD classification, adherence to respiratory treatment (TAI and Morisky Medicaction Adherence Scale - MMAS-8), level of dyspnea (mMRC), disease severity (BODEX), comorbidities (COTE) and physical activity (IPAQ) as well direct costs by assessing health resources utilization (HRU) and exacerbations during last 12 months and respiratory treatment of last 2 months. Study population are patients of 40 years and older, smokers or ex smokers of >= 10 pack/years with previous COPD diagnosis, attending outpatient specialists consults in Argentina, Chile, Colombia, Uruguay, Costa Rica, Guatemala and Mexico. Sample size is targeted to 900 enroled patients in order to ensure 860 patients to achieve statistical power to primary objective. Data source and study conduct: site staff will retrospectively collect the necessary information from the patient's medical record to determine eligibility. Consecutively, patients with diagnosis and stable COPD will be screened and, if eligible, consented and enrolled. There will be only one study visit. For each patient, the physician will collect the following data at visit (from medical records or interviewing in study visit): social demographics, health insurance system, lifestyle, smoking history, comorbidities, level of dyspnea, disease severity, COPD prescribed treatments including therapeutic class, device, modality (rescue/maintenance) and posology during last past 2 months, exacerbations history and healthcare resources utilisation during last 12 months. In addition, the patient will be asked to provide data on disease-related symptomatology assessed during 24 hs day (early morning, daytime and night time symptoms), adherence to inhalers, health-related quality of life (HRQoL) and physical activity. AstraZeneca will develop Data Management Plan (DMP) and a website database platform for the purpose of this study. Data will be registered by PI directly in a website data platform. The LASSYC study is an observational cross sectional study which does not involve or study a specific medicinal product. Because of the non-interventional nature of this study, a simple monitoring plan is required. 100% of source data verification (SDV) of 10% of total enrolled patients, estimating that one site per country would be enough.The Non-Interventional Study will be performed in accordance with ethical principles that are consistent with the Declaration of Helsinki, International Conference on Harmonization (ICH)and Good Clinical Practice (GCP) and the applicable legislation on Non-Interventional Studies.
