Filter by:Consultation time in busy respiratory clinics is inevitably limited and attendance is often disruptive to patients' lives; involves time, expense, travel, and waiting; and can have effects upon occupation. Published work suggests that patient satisfaction with telephone consultations is high and this subject has recently been extensively reviewed by one of the study investigators. In respiratory medicine there is United States (US) data to suggest that the regular telephoning of adolescents with asthma by a specialist nurse can reduce unscheduled use of health service resources. In the United Kingdom (UK), a randomised, controlled trial in primary care has shown that, compared to face to face consultations, use of the telephone can enable greater numbers of patients with asthma to be reviewed. Another of the study investigators has undertaken a feasibility study in a general respiratory clinic and has shown the concept of alternating face to face consultation with telephone consultation to be acceptable to over 80% of patients. Over one third were assessed to be suitable in that they did not need to attend the clinic for either physical examination or for investigations. It is therefore proposed to evaluate the feasibility, acceptability, time savings and safety of the use of telephone consultation in 3 respiratory clinics in the Department of Respiratory Medicine at Charing Cross Hospital.
Some five million people in the United Kingdom (U.K.) have asthma. The British Guidelines on Asthma recommend self management education and the issuing of written personal asthma action plans. The use of such self management education has been shown to be associated with an up to 40% reduction in hospitalisation rates and a 20% reduction in Emergency Department attendances and similar benefits in terms of symptoms and time off work. In asthma, the results are best when the patients are provided with a personalised written action plan explaining how to alter their medications according to a variety of circumstances. Chronic obstructive pulmonary disease is a major cause of hospitalisation in the U.K. and is the fourth biggest single cause of death. A recent Cochrane review regarding the value of self management education in COPD has led to equivocal results although it has shown that those with COPD are willing to take control of their own conditions. The reasons for the different outcomes in asthma and COPD may reflect an inadequate number of trials of the wrong type; interventions that were not appropriate or do not work; lack of the use of written action plans; or assessment of benefit using the wrong outcomes. Given the importance attached to the written action plan, it is essential that such advice is available to all. However, studies of outpatients attending hospitals in the U.K. have shown that 15% may be functionally illiterate and in studies of adults with asthma in the United States (U.S.), 13% have similarly shown to be functionally illiterate. Pictorial advice may therefore be advantageous and, when tested amongst those who are literate, it has been also shown to enhance the recall of spoken medical instructions. The investigators have therefore prepared some pictorial representations which are designed to give advice to those with asthma and COPD about how to recognise the worsening of their conditions and what treatments to alter or initiate as a result. The investigators now need to assess the comprehensibility of those materials amongst a selection of patients with asthma and COPD.
Many studies have shown a high non-attendance rate in hospital outpatient clinics. The investigators have found a non-attendance rate of 25% in their asthma clinics and would like to investigate whether a reminder phone call will improve attendance rates. Patients will be randomised into two groups; one group will receive a reminder phone call one week prior to their hospital consultation and the other group will be managed in the standard manner (i.e. no reminder of any sort). The phone calls will be carried out on a Friday afternoon by a respiratory nurse specialist and a research officer for two asthma clinics based on a Wednesday morning and a Thursday afternoon.
The purpose of this study is to assess the safety and efficacy of the Emphasys Endobronchial Valve (EBV) and procedure (with pulmonary rehabilitation) compared to optimal medical management (with pulmonary rehabilitation) in patients with heterogeneous emphysema.
The purpose of this study is to determine if a program of self management and case management reduces hospitalizations and urgent care visits for patients with chronic obstructive pulmonary disease (COPD).
The goal of this research agenda is to improve the quality of end-of-life care by explicitly identifying values that will guide the decision-making process, with a particular emphasis on the role of ethnic, racial and cultural factors.
Large population-based studies suggest that patients with chronic obstructive pulmonary disease (COPD) are 2 to 3 times at risk for cardiovascular mortality, which accounts for a large proportion of the total number of deaths. How COPD increases the risk of poor cardiovascular outcomes is largely unknown. However, there is growing evidence that persistent low-grade systemic inflammation is present in COPD and that this may contribute to the pathogenesis of atherosclerosis and cardiovascular disease among COPD patients. Inflammation and more specifically, C-reactive protein (CRP), has been linked with all stages of atherosclerosis, including plaque genesis, rupture and subsequent thrombo-fibrosis of vulnerable vessels. Recently, our group has demonstrated in a relatively small study that short-term inhaled corticosteroid (ICS) therapy can repress serum CRP levels in stable COPD patients. Conversely, withdrawal of ICS leads to a marked increase in serum CRP levels. Although very promising, these data cannot be considered definitive because the study was small in size and scope (N=41 patients). Additionally, this study did not address the potential effects of combination therapy with ICS and long-acting β2 agonists (LABA). This is an important short-coming because combination therapy of ICS and LABA have been shown to produce improved clinical outcomes over ICS monotherapy and is commonly used by clinicians in the treatment of moderate to severe COPD. We hypothesize that inhaled fluticasone (Flovent®) reduces systemic inflammation and that combination therapy (Advair®) is more effective than steroids alone in reducing systemic inflammation in COPD. In this proposal, we will implement a randomized controlled trial to determine whether ICS by themselves or in combination with LABAs can: 1. reduce CRP levels in stable COPD patients and 2. reduce other pro-inflammatory cytokines, which have been linked with cardiovascular morbidity and mortality such as interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1)
In this proposal, we will implement a randomized controlled trial to determine whether nocturnal NIMV applied for 3 months: 1) improves (disease-specific) health related quality of life (HRQL) of COPD patients compared to a control group of patients treated with sham NIMV therapy (primary outcome); 2) improves exercise tolerance and walking capacity of COPD patients; and 3) improves heart rate variability and decreases sympathetic tone in COPD.
The purpose of this trial is to study the effects of roflumilast on lung function parameters indicative of hyperinflation in patients with COPD.
The purpose of this study is to evaluate a multifaceted intervention to improve the quality of end-of-life communication between patients with COPD and their primary care providers using information about patients preferences for end of life care and how to communicate and use this information to activate patients, family members, and healthcare providers.
