Prevalence Study and Regular Practice Among General Practitioners in Populations at Risk of Chronic Obstructive Pulmonary Disease (COPD) in Latin America

Study Overview
=================
Brief Summary
-----------------
PUMA is an observational, multicentre, multinational, cross-sectional study with primary care physicians (primary care, general and family physicians). Participants will be selected sequentially among patients at risk for Chronic Obstructive Pulmonary Disease (COPD) who attend primary care consultation (primary care, general and family physicians). The inclusion visit will be a regularly scheduled or spontaneous consultation for patients, and this appointment with the physician will not depend on the study. During the appointment, data will be collected from the patient and the physician.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants with an affirmative response to specific categories on the PUMA questionnaire. | PUMA Questionnaire: Based on the PLATINO questionnaire. Applied to patients to describe different aspects potentially related to Chronic Obstructive Pulmonary Disease (COPD) such as: respiratory symptoms, smoking, respiratory medication, health care resources usage, comorbidieties, etc., as well as the registration of procedures (spirometry and oximetry) carried out and anthropometric data. | Baseline | 
| FEV1 spirometry measures. | FEV1 is the volume of air expelled from the lungs in 1 second. The second visit will be scheduled only for those patients who do not meet criteria for deferring spirometry. | Baseline and visit 2 up to 4 weeks after baseline (if applicable) | 
| SaO2 (Arterial Oxygen Saturation) - pulse oximetry. | The second visit will be scheduled only for those patients who do not meet criteria for deferring spirometry. | Baseline and visit 2 up to 4 weeks after baseline (if applicable) | 
| Number of participants with an affirmative response to specific categories on the Medical History Questionnaire (if applicable). | Questionnaire based on the patient's personal medical history at the site. Its application will be subject to the existence of a prior medical history for the patient at site. If the patient has no prior medical history at site, then this questionnaire will not apply. | Baseline | 
| FEV1/FVC spirometry measures. | Ratio of Forced Expiratory Volume in 1 second (volume of air expelled from the lungs in 1 second) by the Forced Vital Capacity (FVC, the volume of air that can forcibly be blown out after full inspiration) is a spirometric measure (lung function test) used to demonstrate airway obstruction. The second visit will be scheduled only for those patients who do not meet criteria for deferring spirometry. | Baseline and visit 2 up to 4 weeks after baseline (if applicable) | 
| Heart rate (HR) - pulse oximetry. | The second visit will be scheduled only for those patients who do not meet criteria for deferring spirometry. | Baseline and visit 2 up to 4 weeks after baseline (if applicable) |
