Filter by:Bundled payment is a new payment reform that encourages health care providers to improve quality and contain costs of care. These arrangements are being rapidly expanded across the country, but evidence about their impact are lacking. This study will use Medicare claims data to evaluate the effect of participation in a large Medicare bundled payment program on the quality and costs of care for common medical and surgical conditions.
This clinical pharmacology study is performed to evaluate the total systemic exposure and the lung availability of CHF 5993 DPI and pMDI with and without valved holding chamber, in healthy volunteers.
The aim of Patient-Centred Innovations for Persons With Multimorbidity (PACE in MM) study is to reorient the health care system from a single disease focus to a multimorbidity focus; centre on not only disease but also the patient in context; and realign the health care system from separate silos to coordinated collaborations in care. PACE in MM will propose multifaceted innovations in Chronic Disease Prevention and Management (CDPM) that will be grounded in current realities (i.e. Chronic Care Models including Self-Management Programs), that are linked to Primary Care (PC) reform efforts. The study will build on this firm foundation, will design and test promising innovations and will achieve transformation by creating structures to sustain relationships among researchers, decision-makers, practitioners, and patients. The Team will conduct inter-jurisdictional comparisons and is mainly a Quebec (QC) - Ontario (ON) collaboration with participation from 4 other provinces: British Columbia (BC); Manitoba (MB); Nova Scotia (NS); and New Brunswick (NB). The Team's objectives are: 1) to identify factors responsible for success or failure of current CDPM programs linked to the PC reform, by conducting a realist synthesis of their quantitative and qualitative evaluations; 2) to transform consenting CDPM programs identified in Objective 1, by aligning them to promising interventions on patient-centred care for multimorbidity patients, and to test these new innovations' in at least two jurisdictions and compare among jurisdictions; and 3) to foster the scaling-up of innovations informed by Objective 1 and tested/proven in Objective 2, and to conduct research on different approaches to scaling-up. This registration for Clinical Trials only pertains to Objective 2 of the study.
This study will examine the inflammatory response to exercise encompassed as part of a standard pulmonary rehabilitation programme in patients with chronic obstructive pulmonary disease (COPD). Patients will be split into two groups, frequent exacerbators or infrequent exacerbators, dependent upon exacerbation history to compare responses to pulmonary rehabilitation amongst phenotypes.
This prospective, multicenter, cohort study is designed to validate Anxiety Inventory Respiratory Disease questionnaire in patients with Chronic Obstructive Pulmonary Disease (COPD). The primary purpose of this study is to assess the validity of the Anxiety Inventory Respiratory (AIR) scale in detecting anxiety in relation to the DSM-V criteria in patients with COPD. - To evaluate associations between COPD symptom scores assessed by the CAT questionnaire and MMRC dyspnea scale and measures of depression and anxiety - To evaluate associations between physiologic measures of lung function (spirometry) and exercise tolerance (6 minute walk) and measures of depression and anxiety - To evaluate associations between exacerbations of COPD and the prevalence of anxiety and depression in a cohort of COPD patients
In Colorado, marijuana is currently used for both recreational and medicinal purposes.To learn more about the positive and negative long term medical effects of marijuana use. Information obtained during this study may identify new markers that influence the development of lung diseases such as COPD. The Investigators are also interested in learning more about the effects of marijuana use for insomnia and how it may or may not affect sleep.
The purpose of this study is to determine the MRI characteristics of Chronic Obstructive Pulmonary Disease subjects both at baseline and yearly for a period of 5 years, and to correlate these biomarkers with pulmonary function tests, CT scan, 6 Minute-walk tests, and respiratory questionnaires. The central hypothesis is that quantitative assessment of the lung through magnetic resonance imaging of hyperpolarized 3He can detect early alterations in structure and function which are precursors to clinically apparent COPD and that these precursors can be used to predict progression of disease earlier and better than established clinical methods. Novel assessments using 3He MRI will lead to new information about COPD and will be critical for characterizing disease response to therapy. A secondary hypothesis is that a variety of technical improvements in the techniques of hyperpolarized gas MRI will accelerate the translation of this relatively new modality to clinical use.
Respiratory dysfunction following cardiac surgery is well documented and due in part to the location of the incision and nature of the surgery. Post-operative pulmonary complications (PPCs) remain a significant problem following cardiac surgery, sometimes causing prolonged length of stay in hospital as well as increased morbidity and mortality; with the greater risk to older adults and individuals with obstructive lung disease. Positive expiratory pressure (PEP) therapy is thought to increase lung volumes and facilitate secretion clearance. The purpose of this study is to investigate whether the addition of oscillating PEP therapy to standard postoperative treatment is more effective in decreasing the incidence of PPCs and increasing functional capacity at time of discharge in 'high risk' patients undergoing elective cardiac surgery.
The purpose of our study is to establish whether domiciliary use of the Airvo warm passover humidifier can reduce the number of exacerbations in patients with respiratory insufficiency. Participants must have a diagnosis of chronic obstructive pulmonary disease (COPD) and be in long term oxygen therapy (LTOT). The following questions will be investigated: Do outpatients receiving long term oxygen therapy benefit if this is delivered through an Airvo humidification system. The proposed benefits under investigation are: 1. a reduction in the number of exacerbations and thus hospital admissions? 2. an increase in quality of life (QOL)? 3. an improved lung function and thus increased physical activity?
This is a web-based randomized survey to evaluate management of respiratory symptoms among physicians in Sweden. The aim of this study is to determine if there is a gender bias in the diagnosis of COPD and how often physicians identify that chronic refractory breathlessness requires treatment as compared to refractory pain.
