Book Synopsis Design and Analysis of Cluster Randomization Trials in Health Research by : Allan Donner

Download or read book Design and Analysis of Cluster Randomization Trials in Health Research written by Allan Donner. This book was released on 2010-05-17. Available in PDF, EPUB and Kindle. Book excerpt: A cluster randomization trial is one in which intact social units, or clusters of individuals, are randomized to different intervention groups. Trials randomizing clusters have become particularly widespread in the evaluation of non-therapeutic interventions, including lifestyle modification, educational programmes and innovations in the provision of health care. The increasing popularity of this design among health researchers over the past two decades has led to an extensive body of methodology on the subject. This is the first book to present a systematic and united treatment of this topic; it contains distinctive chapters on the history of cluster randomized trials, ethical issues and reporting guidelines.

Book Synopsis Randomized Controlled Trials by : Phyllis Solomon

Download or read book Randomized Controlled Trials written by Phyllis Solomon. This book was released on 2009-02-02. Available in PDF, EPUB and Kindle. Book excerpt: Randomized controlled trials (RCTs) have been the gold standard for health and social service research for generations of professionals. However, even with the development of methods to accommodate a large number of professional perspectives and fields of intervention, there is still no comprehensive resource for learning how to deal with the complex nature of RCTs conducted in community settings. In this book, the authors draw on their extensive experience conducting randomized controlled trials to compile a practical and accessible guide to RCTs in community-based practice settings.

Book Synopsis A Practical Guide to Cluster Randomised Trials in Health Services Research by : Sandra Eldridge

Download or read book A Practical Guide to Cluster Randomised Trials in Health Services Research written by Sandra Eldridge. This book was released on 2012-01-09. Available in PDF, EPUB and Kindle. Book excerpt: Cluster randomised trials are trials in which groups (or clusters) of individuals are randomly allocated to different forms of treatment. In health care, these trials often compare different ways of managing a disease or promoting healthy living, in contrast to conventional randomised trials which randomise individuals to different treatments, classically comparing new drugs with a placebo. They are increasingly common in health services research. This book addresses the statistical, practical, and ethical issues arising from allocating groups of individuals, or clusters, to different interventions. Key features: Guides readers through the stages of conducting a trial, from recruitment to reporting. Presents a wide range of examples with particular emphasis on trials in health services research and primary care, with both principles and techniques explained. Topics are specifically presented in the order in which investigators think about issues when they are designing a trial. Combines information on the latest developments in the field together with a practical guide to the design and implementation of cluster randomised trials. Explains principles and techniques through numerous examples including many from the authors own experience. Includes a wide range of references for those who wish to read further. This book is intended as a practical guide, written for researchers from the health professions including doctors, psychologists, and allied health professionals, as well as statisticians involved in the design, execution, analysis and reporting of cluster randomised trials. Those with a more general interest will find the plentiful examples illuminating.

Book Synopsis Cluster Randomised Trials by : Richard J. Hayes

Download or read book Cluster Randomised Trials written by Richard J. Hayes. This book was released on 2017-07-06. Available in PDF, EPUB and Kindle. Book excerpt: Cluster Randomised Trials, Second Edition discusses the design, conduct, and analysis of trials that randomise groups of individuals to different treatments. It explores the advantages of cluster randomisation, with special attention given to evaluating the effects of interventions against infectious diseases. Avoiding unnecessary mathematical detail, the book covers basic concepts underlying the use of cluster randomisation, such as direct, indirect, and total effects. In the time since the publication of the first edition, the use of cluster randomised trials (CRTs) has increased substantially, which is reflected in the updates to this edition. There are greatly expanded sections on randomisation, sample size estimation, and alternative designs, including new material on stepped wedge designs. There is a new section on handling ordinal outcome data, and an appendix with descriptions and/or generating code of the example data sets. Although the book mainly focuses on medical and public health applications, it shows that the rigorous evidence of intervention effects provided by CRTs has the potential to inform public policy in a wide range of other areas. The book encourages readers to apply the methods to their own trials, reproduce the analyses presented, and explore alternative approaches.
