Active clinical trials for "Lung Diseases, Obstructive"

This prospective study intends to investigate the incidence of postoperative pulmonary complications (PPC) or in-hospital mortality in patients with COPD or at risk for COPD undergoing high-risk noncardiac major surgery and to identify relevant risk factors. This study aims to quantify and compare the diagnostic performance of preoperative functional tests, exercise capacity, clinical assessment tests and predictive scoring systems to predict PPC or in-hospital mortality in these patients.

The aim of this study is to examine the association of COPD maintenance inhalation medication (Inhaled Corticosteroid or ICS) adherence with COPD exacerbation healthcare resource utilization among COPD patients with exacerbation history.

This study aims to determine the extent to which pre-existing long-term conditions are associated with survival following a heart attack (acute myocardial infarction) using observational data from the UK's national heart attack register.

Examine the risk of cardiovascular events (cardiac arrhythmia or myocardial ischemia) or all-cause mortality in Chronic Obstructive Pulmonary Disease (COPD) patients who are new users of Olodaterol or other LABAs available for the treatment of COPD.

The investigator will determine a compliance of two diagnostic techniques (EIT and Body plethysmography) in collective of children and teenagers with obstructive lung disease and a matched control group.

Patients with Chronic Obstructive Lung Disease (COPD) often develop muscle problems, particularly in their legs which makes them more limited in what they can do. The Short Physical Performance Battery (SPPB) is a simple test of standing balance, usual walking speed and ability to stand from a chair. The SPPB may be a useful measure to predict leg function. This study aims to evaluate whether the SPPB is comparable with current exercise tests used in COPD patients, and whether it is useful in predicting disability, death and health resource usage over time.

This is a multi-center, prospective, non-interventional study that aims to evaluate in daily clinical practice, the possible corelation between patIent perception of the ability to perform morning activities and physician evaluation; patients with COPD, grade C and D.

Patients with chronic obstructive pulmonary disease (COPD) have an increased risk of cardiovascular disease,osteoporosis, muscle wasting and diabetes mellitus. Cardiovascular disease is a major cause of death in such patients and it may be related to excess stiffening of the walls of major arteries, such as the aorta, and it has been suggested to represent premature aging. However, there is little known of the development of these problems, which were previously considered to be due to smoking and which is now known not to be the only factor. The investigators will study a large group of patients with mild to very severe airflow obstruction based on the NICE 2010 classification of severity and a matched comparator group free of COPD. This study involves three assessments of the development of the complications of COPD over a five year period. The key measure will be the rate of change in the aortic wall stiffness, an accepted indicator of the risk of heart disease. Changes in wall stiffness will be related to the severity of lung disease; other known cardiovascular risk factors, such as high blood pressure, increased blood cholesterol and to cardiovascular events including heart attacks and death; and to the presence of other complications, such as osteoporosis, muscle wasting and diabetes mellitus. These measures will be analysed in the context of changes in bodywide inflammation and metabolic function and the changes in the rate of ageing. This increased knowledge of interacting factors in the complications of COPD is likely to lead to studies of treatments to avoid their development.

Reports suggest that the Medicaid population includes a higher percentage of smokers than the general population. A high prevalence of smokers in a population is likely to lead to a higher burden of chronic obstructive pulmonary disease (COPD). Few studies have evaluated the economic burden of COPD in a Medicaid population. The objective of this observational, retrospective cohort study is to estimate the economic burden of COPD in subjects with a COPD diagnosis who are enrolled in Medicaid and are receiving maintenance treatment covered by Medicaid. Specifically, the null hypothesis for the primary outcome measure is that no difference is observed in all-cause costs between subjects with and without COPD. The test hypothesis is that there is a difference in all-cause costs between subjects with and without COPD. Secondary outcomes to be evaluated include all-cause resource use and COPD-related costs for the COPD cohort. The study uses a medical and pharmacy administrative claims database called MarketScan Medicaid Database that contains the medical, surgical, and prescription drug experience of nearly 7 million Medicaid recipients. This analysis will use data from 8 states.

This is a multi-center, prospective, non-interventional study that aims to evaluate in daily clinical practice the possible correlation between patient perception of the ability to perform morning activities and the physician's assessment during a regular physical exam in patients with Chronic Obstructive Pulmonary Disease (COPD), group C and D.
