Filter by:Negative pressure ventilation (NPV) is a non-invasive ventilation mode which provide better lung expansion. The major complication of NPV is decrease blood pressure and affects the hemodynamics. The effects of NPV on chronic obstructive pulmonary disease (COPD) patients with pulmonary rehabilitation program remains unknown.
The balance, gait and pain in Chronic Obstructive Pulmonary Disease (COPD) study will aim to investigate the link between balance and gait impairment, and high rates of pain in people with COPD. This cross-sectional observational study will compare balance and gait outcomes for people with COPD who have pain, to those who are pain free.
The purpose of the LINQ™ for COPD study is to characterize Reveal LINQ™ derived data from patients with COPD by assessing the relationship between changes in LINQ™ derived data with COPD exacerbation events.
This prospective study intends to development and validation a patient self-assessment questionnaire. The aim of the self-assessment, by questionnaire, is to estimate the risk of postoperative pulmonary complications (PPC).
A clinical study to investigate if a single dose of an approved drug product (glycopyrrolate Inhalation Solution) reduces trapped air in the lungs of participants with chronic obstructive pulmonary disease. This study is accepting male and female participants over the age of 40. The study will be conducted at one site located in the United States.
Elastosonography is an advanced ultrasound technique, nowadays available in many portable systems, allowing to measure elasticity and stiffness of parenchymatous organs. Its main current applications concern the advanced diagnostics of liver, thyroid and breast nodules. Few studies have applied elastosonography to the respiratory system, and to date no-one has evaluated the elasticity of lung parenchyma in COPD and only one in pulmonary fibrosis. The primary aim of this study is to compare the elasticity features of lung parenchyma, measured by bedside ultrasound integrated with ultrasonography, among three groups of subjects: 1. patients with COPD and/or lung fibrosis; 2. smokers with no functional evidence of COPD or fibrosis; 3. healthy non-smoking volunteers. The secondary aim is to verify the possible correlation of elastosonography-related parameters of lung elasticity/stiffness with results of lung function tests. One hundred and thirty-eight subjects (46 per group) will be enrolled in this experimental study, on both inpatient and outpatient basis. The presence or absence of COPD or fibrosis will be assessed integrating personal history, imaging tests and functional tests prior to enrolment. Smoking habits will also be carefully investigated. Excluded from the study will be all subjects with acute COPD flares, acute respiratory failure, inability to undergo lung ultrasound examination and lung function tests, cognitive impairment, severe motoric disability, cancer, poor survival prognosis. Each participant will undergo standard lung function tests and bediside ultrasound examination integrated with lung elastosonography during the same day. Lung function tests will be performed with a Carefusion MSC Body spirometer following standard procedures. Lung ultrasound will be performed by a skilled physician, using the convex probe of an Esaote Mylab Seven ultrasound system (Esaote, Genova, Italy), equipped with strain elastography module ElaXto©. The participant will remain in the sitting position for the whole ultrasound/elastography procedure, with the examiner systematically scanning intercostal spaces on both sides of the back thorax. After performing a standard lung ultrasound scan to verify the absence of consolidations or signs of respiratory diseases other than COPD, the examiner will activate the elastography module, performing little compressions with the wrist on the convex probe, to obtain adequate elastography images combining ranges of red, green and blue colors. Images will then be analyzed with the software ElaXto©, to obtain the percentage of stiffness in areas of interest of lung parenchyma. Statistical analyses will be focused on comparison of stiffness index across different groups, and on correlation of elastosonographic parameters with lung function tests (FEV1, Tiffeneau index).
This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.
This research work is focused on building and evaluating one of the first evidence-based clinical decision support tools for homecare in the United States. The results of this study have the potential to standardize and individualize nursing decision making using cutting-edge technology and to improve patient outcomes in the homecare setting.
This study is designed to evaluate the effectiveness and implementation of the Assessment of Burden of Chronic Conditions (ABCC)-tool for patients with COPD, asthma, diabetes mellitus type 2 or heart failure (and any combination of these conditions) in real-life routine practice. The ABCC-tool consists of a questionnaire, a visualisation using balloons that is based on cut-off points, and treatment advice. The ABCC-tool is intended to be used in daily healthcare practice, is designed to monitor a patient's integrated health status over time, to facilitate shared decision making, and to stimulate self-management. The study has a pragmatic clustered quasi-experimental design with two arms. The intervention group will use the ABCC-tool and the control group will receive usual care. The study will be implemented at a general practice-level, and has a follow-up period of 18 months. The primary outcome is change in perceived quality of care, as measured with the Patient Assessment of Chronic Illness Care (PACIC), as compared to usual care after 18 months. It is hypothesized that the change in perceived quality of care is significantly higher in the group using the ABCC-tool as compared to the group that receives usual care. Additionally the implementation of the ABCC-tool in general practices will be evaluated in 12 general practices. The implementation study will evaluate the context of caregivers with the Consolidated Framework for Implementation Research, the process of implementation with the RE-AIM framework, and fidelity to the intervention with the fidelity framework.
Purpose: to evaluate the immediate effect of automated oxygen titration compared to usual fixed-dose oxygen treatment during exercise in patients with COPD on long-term oxygen treatment. Methods: The study will be conducted as a double blinded randomized crossover trial with two arms. 40 ambulatory patients with COPD and home oxygen treatment will be included from AHH Hospital's catchment area. The patients will conduct two Endurance Shuttle Walk Tests (ESWT) in a crossover design using an O2matic device to deliver a variable oxygen dosage set at an SpO2-target of 90-94% and an O2-flow of 0 - 15 liters/min and using the patients´ usual fixed-dose oxygen delivery, in a randomized order. In both arms O2matic will monitor pulse rate and SpO2 continuously during the test, but only in the automated oxygen titration arm will O2matic adjust oxygen flow. The patient and the physiotherapist supervising the tests will be blinded to the oxygen dose. Primary outcome is the changes in perceived dyspnea intensity using Borg CR10 scale between walking with automated titration compared to fixed-dose treatment. Secondary outcomes are differences in walking time, the average oxygen consumption between automated oxygen titration and fixed-dose treatment and difference in time spent within acceptable SpO2-interval.
