Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The purpose of this study is to distribute a questionnaire created for individuals living with chronic obstructive pulmonary disease (COPD) to assess their activities, participation, and healthcare and COPD-related research priorities. The data collected will be compared across diagnosed COPD stages and disease severity to determine the extent to which adults with COPD participate in the listed activities and identify their primary research and healthcare related priorities. The questionnaire was originally developed based on past research then verified by a panel of COPD and participation experts; as well as, individuals living with COPD in the form of focus groups. The questionnaire will now be administered to 200 individuals living COPD (50 in each GOLD stage) at three sites across Montreal where clinical data for each participant will be available. This phase will help establish the reliability of the questionnaire.

Three main classes of inhaled treatment exist for chronic obstructive pulmonary disease (COPD): Beta2-adrenergic agonists (which may be short (SABA) or long (LABA) acting), long-acting muscarinic acetylcholine receptor antagonists (LAMA), and inhaled corticosteroids (ICS). For subjects at higher risk of exacerbation, treatment with all these three classes of medication is recommended. This study aims to explore the potential utility of a device called single inhaler triple combination or fluticasone furoate/ umeclidinium/ vilanterol (FF/UMEC/VI) inhaler containing all three groups of compound. This is a mixed methods study with a qualitative phase and a quantitative Discrete Choice Experiment (DCE) phase and will be conducted in four stages: qualitative concept elicitation, DCE development, DCE piloting and testing, and conduct of the DCE. The study will conducted in the United Kingdom (UK), United States (US) and Germany and approximately 573 subjects with COPD will be included.

This is a prospective study to determine the relationships between pauci-inflammatory exacerbations and diastolic dysfunction, and their implications in hospitalized patients with acute exacerbations of COPD. To assess changes within subjects from stable to acute phase, a number of comparisons will be made in subjects enrolled during acute exacerbation with similar measurements made in the stable phase after recovery from exacerbation after at least 35 days from index hospitalization or prior exacerbation.

Open-label comparative multicentric cohort study in COPD patients with LABA/ICS, switched to either tiotropium/olodaterol and observed for 12 weeks approximately.

The investigators aim to determine the optimal number of measurements required for multiple-breath-washout derived lung function parameters in adults with pulmonary disease as well as in healthy controls

To develop predictive models for short-term readmission (60 days) and medium term (one year) for patients with an exacerbation of COPD (eCOPD) which are admitted to any of the participant hospitals. To identify factors contributing to readmission from the time of discharge from the index admission to the studied readmission time. Methodology. Design: Prospective cohort study with a nested case control study, with follow up to one year. Patients: 1500 patients admitted over a year and a half in any of the 9 participant hospitals by an eCOPD. Methods: During admission, background information on patient situation prior to admission, data of the ED during admission, and discharge planning, will be collected from medical history. The investigators will also survey patients (generic and specific health-related quality life -HRQoL- dependence, social support, presence of fragility). All patients will be followed to determining whether any readmission until 60 and up to one year of discharge from the index admission occurs. Patients readmitted at the first 60 days after discharge will be surveyed on a number of possible causes of readmission (continuity of care, medication, complications, individual and social factors). A one to one control group will be established to compare different factors studied in the case group (readmission). Statistical analysis: predictive models will be developed from the derivation sample, and validated in a validation sample. Also, the factors evaluated in the case-control study will be compared using appropriate test for paired samples.

This study will test how well short questionnaires, with and without a simple breathing test called 'peak flow', can identify people with COPD compared to the gold-standard diagnostic test called spirometry. We will test this in 10,500 people from three low- and middle-income countries, namely Nepal, Peru and Uganda. We will also examine the feasibility of implementing our case-finding intervention at scale.

This study will evaluate the diagnostic measures (including blood eosinophil counts) commonly used by lung specialist's in routine clinical care of subjects with COPD in Germany and how these diagnostic tests influence the physician's treatment decisions. The study will be conducted in three parts. In the first part, lung specialist's, who will not participate in the survey, will develop doctor's questionnaire. The second part is an interventional cross-sectional study, wherein approximately 30 lung specialists will be enrolled and data on their perspective on diagnosis and treatment of COPD subjects will be collected via the revised doctor's questionnaire. The third part is a retrospective non-interventional study where each doctor will collect retrospective data from selected subjects with COPD from the time of informed consent up to 12 months before. The retrospective data will be collected from subject files of approximately 250 subjects with COPD.

The aim of this study is to compare oxygen desaturation during two tests: the 6 minute walk test and the 3 minute step test, for COPD patients.

An open access study that will define and collect digital measures of coughing in multiple populations and public spaces using various means of audio data collection.
