Using real data sets, chapters equip the reader with all of the key knowledge and skills required to design, run, analyse and report an RCT. Coverage includes: · Step-by-step guidance on analysing data · How to assess the reliability and validity of results · Advice on balancing the demands of various stakeholders Essential reading for postgraduate and more experienced researchers, as well as teachers and educationalists seeking to increase their knowledge and understanding of the use of such methods in education.
Download or read book Analysis of Data from Randomized Controlled Trials written by Jos W.R. Twisk and published by Springer Nature. This book was released on 2021-10-15 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a practical guide to the analysis of data from randomized controlled trials (RCT). It gives an answer to the question of how to estimate the intervention effect in an appropriate way. This problem is examined for different RCT designs, such as RCTs with one follow-up measurement, RCTs with more than one follow-up measurement, cluster RCTs, cross-over trials, stepped wedge trials, and N-of-1 trials. The statistical methods are explained in a non-mathematical way and are illustrated by extensive examples. All datasets used in the book are available for download, so readers can reanalyse the examples to gain a better understanding of the methods used. Although most examples are taken from epidemiological and clinical studies, this book is also highly recommended for researchers working in other fields.
Download or read book Randomised Controlled Clinical Trials written by Christopher J. Bulpitt and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bradford Hill has defined a clinical trial as "A carefully and ethically designed experiment with the aim of answering some precisely framed question" [1]. This definition specifies a careful design and requires the provision of adequate controls. Random allocation of treatments to subjects is important to ensure is entitled that the treated and control groups are similar. Therefore this book Randomised Controlled Clinical Trials. We can define a randomised controlled trial by rewriting Bradford Hill's definition as follows, "A carefully and ethi cally designed experiment which includes the provision of adequate and ap propriate controls by a process of randomisation, so that precisely framed questions can be answered. " I am a firm advocate ofRandomised Controlled Clinical Trials but intend to give a balanced view of the advantages and disadvantages of these ethical experiments. This book is directed primarily at the medical research worker, although certain chapters may find a wider application. When discussing a randomised controlled trial, it is neither practicable nor desirable to divorce theory from practice, however the first ten chapters con centrate mainly on theory, and the remainder focus on practice. The segment on trial design is followed by sections on writing the protocol, designing the forms, conducting the trial, and analysing the results. This book is meant to serve both as a reference manual and a practical guide to the design and performance of a trial.

Download or read book Essential Concepts in Clinical Research written by Kenneth Schulz and published by Elsevier Health Sciences. This book was released on 2018-07-19 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical guide speaks to two audiences: those who read and those who conduct research. Clinicians are medical detectives by training. For each patient, they assemble clinical clues to establish causes of signs and symptoms. The task involves both clinical acumen and knowledge of medical research. This book helps guide clinicians through this detective work, by enabling them to make sense of research and to review medical literature critically. It will also be invaluable to researchers who conduct clinical research, particularly randomized controlled trials. Building on previously published, peer-reviewed articles from The Lancet, this handbook is essential for busy clinicians and active researchers interested in research methods. - Written by leaders in the field of clinical research who have published extensively with authorship of hundreds of articles in medical journals. - The authorship includes one of the three authors of the CONSORT guidelines for the reporting of randomized controlled trials. - The book presents the essential concepts to a wide array of topics including randomized control trials, descriptive studies, cohort studies, case-control studies, bias, and screening tests. - The book utilises a readable and humorous prose style, lightening what can be a difficult area for clinical readers. - Derived from decades of teaching clinical research in seminar settings the book will empower clinicians to make sense of, and critically appraise, current medical research and will enable researchers to enrich the quality of their work. For this Second Edition, the authors have revised and updated the original 16 chapters and added six new chapters. For busy clinicians and active researchers interested in research methods, this book provides helpful tools to derive satisfaction - indeed, fun - from clinical science.
Download or read book When Is It Possible to Conduct a Randomized Controlled Trial in Education at Reduced Cost Using Existing Data Sources written by Coalition for Evidence-based Policy and published by . This book was released on 2007 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this Guide is to advise researchers, policymakers, and others on when it is possible to conduct a high-quality randomized controlled trial in education at reduced cost. Well-designed randomized controlled trials are recognized as the gold standard for evaluating the effectiveness of an intervention (i.e., program or practice) in many diverse fields, such as medicine, welfare and employment, psychology, and education. But they have been relatively rare in education, in part because of a perception among policymakers, researchers, and others that such studies are too costly and too administratively burdensome on schools to be practical. This guide explains that, in many circumstances, it may in fact be possible to conduct a randomized controlled trial at modest cost and with minimal burden, by measuring outcomes using school-administered test scores or other administrative data that are already collected for other purposes. This guide includes two main sections: (1) Conditions that offer the opportunity to conduct a randomized controlled trial at reduced cost; and (2) Examples of well-designed randomized controlled trials conducted at reduced cost.
Download or read book Randomized Controlled Trials written by Phyllis Solomon and published by Oxford University Press. This book was released on 2009-02-02 with total page 224 pages. 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.
Download or read book Taming Randomized Controlled Trials in Education written by Keith Morrison and published by Routledge. This book was released on 2020-07-07 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a recent surge in the use of randomized controlled trials (RCTs) within education globally, with disproportionate claims being made about what they show, ‘what works’, and what constitutes the best ‘evidence’. Drawing on up-to-date scholarship from across the world, Taming Randomized Controlled Trials in Education critically addresses the increased use of RCTs in education, exploring their benefits, limits and cautions, and ultimately questioning the prominence given to them. While acknowledging that randomized controlled trials do have some place in education, the book nevertheless argues that this place should be limited. Drawing together all arguments for and against RCTs in a comprehensive and easily accessible single volume, the book also adds new perspectives and insights to the conversation; crucially, the book considers the limits of their usefulness and applicability in education, raising a range of largely unexplored concerns about their use. Chapters include discussions on: The impact of complexity theory and chaos theory. Design issues and sampling in randomized controlled trials. Learning from clinical trials. Data analysis in randomized controlled trials. Reporting, evaluating and generalizing from randomized controlled trials. Considering key issues in understanding and interrogating research evidence, this book is ideal reading for all students on Research Methods modules, as well as those interested in undertaking and reviewing research in the field of education.
Download or read book Control and the Therapeutic Trial written by Martin Edwards and published by BRILL. This book was released on 2015-07-14 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Listen to podcast with the author How do doctors decide whether their drugs, or other treatments, actually work? In practice this can be fiendishly difficult. Nowadays the gold standard is the randomised controlled trial (RCT). But the RCT is a recent invention, and the story of how it came to dominate therapeutic evaluation from the latter half of the twentieth century involves acrimony, confrontation, and manipulation of the powerful rhetoric of ‘control’. Control and the Therapeutic Trial examines the development of the RCT from the eclectic collection of methodologies available to practitioners in the early-twentieth century. In particular, it explores the British Medical Research Council’s (MRC) exploitation of the term ‘controlled’ to help establish its own ‘controlled trials’ as the gold standard for therapeutic evaluation, and, ultimately, the MRC itself as the proper authority to adjudicate on therapeutic efficacy. This rhetorical power still clings, and is exploited today. Control and the Therapeutic Trial will be of interest not only to historians of twentieth-century medicine and practising clinicians who take therapeutic decisions, but to anyone who seeks a broader insight into the forces that shaped, and control, the modern controlled trial.
Download or read book Critical Thinking in Clinical Research written by Felipe Fregni and published by Oxford University Press. This book was released on 2018-03-13 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most crucial skills a clinician, scientist, or student can learn is to create, conduct, and interpret the conclusions of a clinical study. Critical Thinking in Clinical Research teaches these fundamentals in four distinct sections, called "units": the first unit focuses on issues surrounding the design of a study such as population, question selection, randomization, and blinding; Unit 2 presents statistical methods such as analyzing data collected, how to present and discuss the data concisely; the third unit covers practical aspects such as methodology, organizational considerations, principles of trial conduct and reporting; and the final unit delves into study designs, providing the advantages and drawbacks of each design style. Each chapter begins with a short introduction, followed by a hypothetical case that challenges the reader to make decisions, to consider pros and cons of specific approaches, and to evaluate options based on specific conditions. Knowing how to critically read and understand scientific papers and to collect, analyze, and interpret research data, which they in turn can then present in their own scientific manuscript makes this book the perfect resource for anyone looking to contribute to the wealth of scientific and medical inquiry.

Divided into three parts, the book provides a deconstruction of key texts related to evidence based practice, weaving together contemporary themes in healthcare research. Deconstructing Evidence Based Practice is essential reading for nurses and other health practitioners who need to understand more about evidence-based practice and who want to learn methods of critical thinking that will be invaluable in judiciously informing their practice.
Download or read book Ending Medical Reversal written by Vinayak K. Prasad and published by JHU Press. This book was released on 2015-11 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medications such as Vioxx and procedures such as vertebroplasty for back pain are among the medical "advances" that turned out to be dangerous or useless. What Dr. Vinayak K. Prasad and Dr. Adam S. Cifu call medical reversal happens when doctors start using a medication, procedure, or diagnostic tool without a robust evidence base—and then stop using it when it is found not to help, or even to harm, patients. In Ending Medical Reversal, Drs. Prasad and Cifu narrate fascinating stories from every corner of medicine to explore why medical reversals occur, how they are harmful, and what can be done to avoid them. They explore the difference between medical innovations that improve care and those that only appear to be promising. They also outline a comprehensive plan to reform medical education, research funding and protocols, and the process for approving new drugs that will ensure that more of what gets done in doctors' offices and hospitals is truly effective. "Every doctor should read this book."—JAMA Internal Medicine "[A]n excellent and realistic discussion of some of the horror stories that occur in medical practice . . . Highly recommended."—Choice "Ending Medical Reversal goes far in teaching medical students and practicing physicians alike how to learn on our own."—The Lancet "This has to be on the reading list for medical and nursing students."—Nursing Times "Ending Medical Reversal presents persuasive evidence that many current standard-of-care treatments are probably ineffective or harmful, thoroughly explains how such treatments came to be accepted, and proposes a number of ways to address the general problem (only some of which involve avaricious companies and mercenary physicians) and minimize its impact on a specific patient."—Journal of Clinical Research Best Practices "Dr. Prasad and Dr. Cifu offer a five-step plan, including pointers for determining if a given treatment is really able to do what you want it to do, and advice on finding a like-minded doctor who won't object to a certain amount of back-seat driving."—The New York Times "When I describe Ending Medical Reversal as revolutionary, I don't use the term lightly. Go out and read it—right now."—Common Sense Family Doctor "Should be considered for undergraduate reading lists. Keep a copy in the pharmacy or your briefcase as a great icebreaker or discussion point with other local healthcare professionals."—The Pharmaceutical Journal
