Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The purpose of this study is to examine genetic factors that influence the development of chronic obstructive pulmonary disease (COPD) in Hispanics, a minority group at high risk for the disease.

To localize within the genome a chronic obstructive pulmonary disease susceptibility gene.

A retrospective cohort study of all patients treated for type II (hypercapnic) respiratory failure with either High-Flow Oxygen Therapy or Non-Invasive Ventilation in a general adult hospital.

This is a pilot study that will evaluate the feasibility of collecting increasing amounts of clinical study data from subjects through sensor and web/app based methods and integrating it with data from their EHR to facilitate more efficient and meaningful research with acceptable quality. Approximately 100 subjects with asthma and 100 subjects with chronic obstructive pulmonary disease (COPD) will be enrolled in this prospective study. The subjects will be identified through integrated EHR records following which eligible subjects will receive study devices and training on proper use of the devices at Baseline visit. Data will be collected remotely from subject reports, devices and sensors over six months.

This non-interventional study aims at assessing stable GOLD C and D COPD patient's perception of daily and weekly symptoms variability and their impact on daily activities. It will also explore the current practice in management of stable GOLD C and D COPD patients.

The agricultural environment presents a unique profile in terms of epidemiology of pulmonary diseases. Certainly due to persistent exposure to organic particles, the prevalence of COPD is higher in farmers than in the general population, despite less smoking. It is likely that the risk of COPD depends on several factors, such as the type of farm, local conditions and the region where the farm is located. It is important to diagnose COPD at an early stage in order to initiate appropriate therapy, and implement secondary prevention with a view to limiting deterioration of respiratory function and reducing complications. In this context, the aims of BM3R project were: (1) to study the epidemiology of COPD in a large representative sample of French farmers, in order to identify the types of farming, working conditions and regions that are associated with the presence of COPD; and (2) to develop a score to identify patients at risk and optimise diagnosis of COPD in the context of a screening programme.

This is a 1 year longitudinal study to establish a related index system for chronic obstructive pulmonary disease(COPD) quality control.Clinical and economic data of COPD patients will be collected and analyzed.

The main purpose of the study is to assess the burden of illness for, COPD using both patient-reported symptom burden and claims-based economic burden, among the subjects treated with single-inhaler dual therapy treatments, Fluticasone/Salmeterol FLUT/SAL; Advair) or Umeclidinium/Vilanterol (UMEC/VI; Anoro) to support Global Initiative for Chronic Lung Disease (GOLD) category B recommendations. The study will use a health plan recruitment strategy and subject's will be recruited using Optum's health plan recruitment strategy to collect information relating to the subject's condition history, current treatment, smoking history, symptoms and symptom severity (Modified Medical Research Council Dyspnoea Scale [mMRC] and COPD Assessment Test [CAT]), and demographic and sociodemographic characteristics. A total of 2700 subject's, are planned to be enrolled in the study to reach the target evaluable sample size, n=770 subjects. Following completion of data collection, results of the survey, will be merged with claims data, covering the 12-month Baseline period for analysis. Pharmacy and medical claims data, will be used to calculate all-cause and COPD-related health care utilization and costs, treatment patterns, and Baseline clinical characteristics. The study duration is estimated to be of 12-months.

This study is a multicentered and non-interventional prospective cohort study. Study centers shall be the institutions where the examinations, adopted in the ACO diagnostic criteria9) from The Japanese Respiratory Society, are performed at least once a year as a part of their regular practice. Physicians participating in the study will consecutively register by means of central registration outpatients who have the characteristics of COPD in the ACO diagnostic criteria9) from The Japanese Respiratory Society, and who have been confirmed to satisfy the inclusion criteria whereas not violating the exclusion criteria.

A prospective multi-center study to define the sensitivity and specificity of CAPTURE for identifying previously undiagnosed patients with clinically significant COPD in a broad range of primary care settings.
