The short-term prognosis of advanced refractory heart failure is extremely poor and closely correlated with progressive left ventricular dysfunction. The identification of the negative effects of conduction delay on cardiac performance, observed in almost 50% of heart failure patients, disclosed a new research field addressing the correction of electrical(More)
Objective To evaluate effectiveness of physiotherapy management in patients experiencing whiplash associated disorder II, on clinically relevant outcomes in the short and longer term. Design Systematic review and meta-analysis. Two reviewers independently searched information sources, assessed studies for inclusion, evaluated risk of bias and extracted(More)
OBJECTIVES To examine the management of diabetes between 2001 and 2007 in the United Kingdom and to assess whether changes in the quality of care reflect existing temporal trends or are a direct result of the implementation of the quality and outcomes framework. DESIGN Retrospective cohort study. SETTING 147 general practices (annual list size over 1(More)
PURPOSE To develop expert consensus on a suite of reporting standards for HRQL outcomes of RCTs. METHODS A Task Force of The International Society of Quality of Life Research (ISOQOL) undertook a systematic review of the literature to identify candidate reporting standards for HRQL in RCTs. Subsequently, a web-based survey was circulated to the ISOQOL(More)
OBJECTIVE To determine the clinical effectiveness of wound edge protection devices in reducing surgical site infection after abdominal surgery. DESIGN Multicentre observer blinded randomised controlled trial. PARTICIPANTS Patients undergoing laparotomy at 21 UK hospitals. INTERVENTIONS Standard care or the use of a wound edge protection device during(More)
To inform clinical guidelines and patient care we need high quality evidence on the relative benefits and harms of intervention. Patient reported outcome (PRO) data from clinical trials can "empower patients to make decisions based on their values" and "level the playing field between physician and patient". While clinicians have a good understanding of the(More)
BACKGROUND Interim analysis of accumulating trial data is important to protect participant safety during randomized controlled trials (RCTs). Data Monitoring Committees (DMCs) often undertake such analyses, but their widening role may lead to extended use of interim analysis or recommendations that could potentially bias trial results. METHODS Systematic(More)
BACKGROUND The rationale for centre selection in randomised controlled trials (RCTs) is often unclear but may have important implications for the generalisability of trial results. The aims of this study were to evaluate the factors which currently influence centre selection in RCTs and consider how generalisability considerations inform current and optimal(More)
BACKGROUND Patient reported outcomes (PROs) are increasingly assessed in clinical trials, and guidelines are available to inform the design and reporting of such trials. However, researchers involved in PRO data collection report that specific guidance on 'in-trial' activity (recruitment, data collection and data inputting) and the management of(More)
BACKGROUND Recent debate suggests Huntington's disease (HD) may be more prevalent than previously reported. In addition, relatively little is known about current disease management. This study aims to provide epidemiological data and describe the pharmacological management of HD in the United Kingdom. METHODS A primary care research database was accessed(More)
