Many of the available disability outcome measures used in clinical trials of multiple sclerosis are insensitive to change over time, inadequately validated, or insensitive to patient-perceived health status or quality of life. Increasing focus on therapies that slow or reverse disability progression makes it essential to refine existing measures or to develop new tools. Major changes to the exp...

BACKGROUND Use of core outcome sets in research has been proposed as a method for countering the problems caused by heterogeneity of outcome measure reporting. Heterogeneity of outcome measure reporting occurs in Hirschsprung's disease (HD) research and is limiting the development of a robust evidence base to support clinical practice. METHODS Candidate outcome measures have been identified t...

OBJECTIVES The aim of this study was to examine the efficacy of budesonide administered once daily compared to twice daily in asthma. METHODOLOGY Meta-analysis of randomised controlled trials comparing budesonide administered once versus twice a day that presented data on at least one clinical outcome measure was conducted. RESULTS A total of 10 studies, with 1922 children and adults with a...

Have state-of-the-art clinical trials failed to deliver treatments for neurodegenerative diseases because of shortcomings in the rating scales used? This Review assesses two methodological limitations of rating scales that might help to answer this question. First, the numbers generated by most rating scales do not satisfy the criteria for rigorous measurements. Second, we do not really know wh...

Elderly pneumonia patients have various underlying diseases and social backgrounds, and it is difficult to predict their mortality using the current severity assessment tools. However, aspiration is a risk factor for mortality in pneumonia patients. In the evaluation of aspiration, endoscopic and video fluoroscopic methods are reliable but cannot be performed in all pneumonia patients. We evalu...

BACKGROUND Use of automated systems to aid identification of patient deterioration in routine hospital practice is limited and their impact on patient outcomes remains unclear. This study was designed to evaluate the feasibility of implementing an electronic observation chart with automated early warning score (EWS) calculation in the high-acuity area of an emergency department. METHODS This ...

BACKGROUND With the help of a measurement feedback system, the treatment strategy for individual patients with rheumatoid arthritis (RA) can be adjusted to achieve optimal control of disease activity. OBJECTIVE To study whether a measurement feedback system is effective in reducing disease activity in patients with RA. METHODS Forty eight rheumatologists and 264 patients participated in a c...

BACKGROUND Poor adherence to antihypertensive drug regimens is believed to be a major contributor to treatment failure. Electronic monitoring of adherence may improve adherence and allow differentiation between those who are nonadherent and those who are pharmacologically nonresponsive. This study was designed to evaluate the effectiveness of electronic monitoring of adherence in lowering blood...

PURPOSE To produce an internationally valid tool to assess skill in performing strabismus surgery. METHODS A panel of 7 content experts adapted a previously published tool for assessing phacoemulsification by using a modified Dreyfus scale of skill acquisition and providing behavioral descriptors for each level of skill in each category. The tools were then reviewed by 12 international conten...

BACKGROUND Randomised controlled trials are becoming increasingly costly and time-consuming. In 2011, Royston and colleagues proposed a particular class of multi-arm multi-stage (MAMS) designs intended to speed up the evaluation of new treatments in phase II and III clinical trials. Their design, which controls the type I error rate and power for each pairwise comparison, discontinues randomisa...
